A display time 423 indicates a time during which display is continued in the display pattern of the image attribute information 413 including the display time 423. In the example of FIG. 4, when the display time 423 is “infinite”, the display of the display pattern of the image attribute information 413 including the display time 423 is displayed while the warning is displayed. A display position 424 indicates a position on the display device 112 of the icon display device 11 where the image data of the image ID 421 of the image attribute information 413 including the display position 424 is displayed.

  The animation information 414 has a repetition 431, a period 432, and the like. The repeat 431 indicates whether or not to repeatedly display the display pattern indicated by each image attribute information 413 included in the same image set data 402. In the example of FIG. 4, the repetition 431 “present” indicates that the display pattern is repeatedly displayed. The repetition 431 “None” indicates that the display pattern is not repeatedly displayed. A period 432 indicates a period in which the repeated display is performed when the repetition 431 included in the same animation information 414 is “present”.

  A display priority 415 indicates the priority of the display image set data 402.

  In the example of FIG. 4, it is assumed that the image attribute information 413 included in one image set data 402 is sorted in the display order. When a plurality of image data starts to be displayed simultaneously, the display time difference 422 is set to the same value. Here, it is assumed that the same image group having the display time difference 422 is displayed at the same time by superimposing them in the sorted display order.

  Here, a specific example of the image set data 402 of the image set management data 163 will be described with reference to FIG. 5, FIG. 6, and FIG. FIG. 5 is a specific example of the image set data 402 for warning an engine failure. FIG. 6 is a specific example of the image set data 402 for warning a tire puncture. FIG. 7 is a specific example of the image set data 402 for warning the tire pressure drop. In order to omit the description, the same reference numerals are given to the same items as those in the image set management data 163 in FIG. 4 described above in FIGS.

  First, an example of the image set data 402 in FIG. 5 will be described.

  In FIG. 5, image set data 402 for warning an engine failure includes four pieces of image attribute information 413. That is, four display patterns are used to warn of engine failure. As described above, since the image attribute information 413 is sorted in the display order, in the example of FIG. 5, in the order of the image ID 421 “1001”, the image ID 421 “1002”, the image ID 421 “1003”, and the image ID 421 “1004”. Is displayed.

  Here, since the display time difference 422 is “0 s”, both the image with the image ID 421 “1001” and the image with the image ID 421 “1002” are displayed at the same time from the start of the engine failure warning display. . Further, both the image with the image ID 421 “1001” and the image with the image ID 421 “1002” indicate that the display time 423 is “infinite”, so that the engine failure is always displayed while the warning is displayed.

  The image with the image ID 421 “1003” starts to be displayed after the display time difference 422 “3 s” from the start of the display of the engine failure warning, and further the display time 423 “3 s” from the start of the image display with the image ID 421 “1003”. Indicates to continue displaying.

  Similarly, the display of the image with the image ID 421 “1004” starts after the display time difference 422 “6s” from the start of the display of the engine failure warning, and further the display time 423 “4s” from the start of the image display with the image ID 421 “1004”. Indicates that display will continue for a while.

  Since the repetition 431 of the animation information 414 is “present” and the period 432 is “10 s”, the image ID 421 “1001”, the image ID 421 “1002”, the image ID 421 “1003”, and the image ID 421 “1004” described above. Is repeatedly displayed with a period of “10 s”. Here, as described above, the image ID 421 “1001” and the image ID 421 “1002” are displayed while the engine failure warning is displayed. The image with the image ID 421 “1003” is displayed for “3 s” after “3 s” from the start of the display of the engine failure. Furthermore, the image with the image ID 421 “1004” is displayed for “4 s” after starting display after “6 s” from the start of display of the engine failure. Therefore, in the example of FIG. 5, the images with the image ID 421 “1001” and the image ID 421 “1002” are displayed throughout the display of the engine failure warning, and the image with the image ID 421 “1003” and the image ID 421 “1004” are displayed. Images are displayed alternately.

  Next, an example of the image set data 402 in FIG. 6 will be described.

  In FIG. 6, image set data 402 for warning a tire puncture includes three pieces of image attribute information 413. That is, three display patterns are used to warn of tire punctures. As described above, since the image attribute information 413 is sorted in the display order, the image ID 421 “2101”, the image ID 421 “2102”, and the image ID 421 “2103” are displayed in the order shown in FIG. Show.

  Here, since the display time difference 422 is “0 s”, the image with the image ID 421 “2101” is displayed first, and further displayed for the display time 423 “2 s” from the start of displaying the tire puncture warning. .

  The image with the image ID 421 “2102” starts to be displayed after the display time difference 422 “2s” from the start of the display of the tire puncture warning, and is further displayed for the display time 423 “2s” from the start of the image display with the image ID 421 “2102”. Indicates that it will continue.

  Similarly, the image with the image ID 421 “2103” starts to be displayed after the display time difference 422 “4s” from the start of the display of the tire puncture warning, and further, between the display time 423 “2s” from the start of the image display with the image ID 421 “2103”. Indicates to continue displaying.

  Since the repetition 431 of the animation information 414 is “present” and the period 432 is “6s”, the above-described image ID 421 “2101”, image ID 421 “2102”, and image ID 421 “2103” are set in the “6s” period. Indicates repeated display. Here, as described above, the image ID 421 “2101” is continuously displayed for “2 s” from the start of displaying the tire puncture warning. Further, the image with the image ID 421 “2102” starts to be displayed “2 s” after the start of displaying the tire puncture warning, and then continues to be displayed for “2 s”. Further, the image with the image ID 421 “2103” is displayed for “2 s” after starting display after “4 s” from the start of displaying the tire puncture warning. Accordingly, the example of FIG. 6 indicates that the image with the image ID 421 “2101”, the image with the image ID 421 “2102”, and the image with the image ID 421 “2103” are displayed alternately.

  An example of the image set data 402 in FIG. 7 will be described.

  In FIG. 7, the image set data 402 for warning the tire pressure drop includes two pieces of image attribute information 413. That is, two display patterns are used to warn of a decrease in tire air pressure. As described above, since the image attribute information 413 is sorted in the display order, the example in FIG. 7 indicates that only the image ID 421 “2101” is displayed at a different display position 424.

  Here, the image of the image ID 421 “2201” to be displayed first has a display time difference 422 of “0 s”, a display time 423 of “1 s”, and a display position 424 “(20, 20)”. This indicates that the display is continued at the position defined by “(20, 20)” for “1 s” from the start of the warning display.

  Further, the image with the image ID 421 “2201” to be displayed later is because the display time difference 422 is “1 s”, the display time 423 is “1 s”, and the display position 424 “(20, 40)”. After “1 s” from the start of display of the warning of decrease, it indicates that the display is continued at the position defined by “(20, 40)” for “1 s”.

  Further, since the repetition 431 of the animation information 414 is “present” and the period 432 is “2s”, it indicates that the above-described display is repeatedly displayed at the “2s” period. Here, as described above, the image ID 421 “2101” to be displayed first is displayed at a position defined by “(20, 20)”. The image ID 421 “2101” to be displayed later is displayed at a position defined by “(20, 40)”. Therefore, the example of FIG. 7 indicates that images with the same image ID 421 “2101” are alternately displayed at different positions.

  Next, an example of the image element management data 164 will be described with reference to FIG.

  In FIG. 8, the image element management data 164 includes one display image number 801, a plurality of display image elements 802, and the like. Here, it is assumed that display image elements 802 are set by the number of images output to the icon display device 11.

  The display image number 801 is the number of display image elements 802 included in the image element management data 164.

  Each display image element 802 includes an image ID 811, image data 812, and the like. The image ID 811 is image data identification information. Image data 812 is image data itself.

  Next, information in the ROM 114 of the icon display device 11 will be described with reference to FIG.

  In FIG. 9, the ROM 114 stores correspondence management data 901, image management data 902, display image data 903, and the like.

  The correspondence management data 901 stores management information such as warning information displayed on the display device 112. The image management data 902 stores image data to be displayed on the display device 112. The display image data 903 stores an image to be displayed on the icon display regardless of a warning image, a sign image, and the like such as a character frame and a background. Since the information in the display image data 903 is the same as that of the prior art icon device, the description thereof is omitted here.

  Next, an example of the correspondence management data 901 will be described with reference to FIG.

  In FIG. 10, the correspondence management data 901 includes one correspondence data number 1001 and a plurality of correspondence data 1002. The number of correspondence data 1001 indicates the number of correspondence data 1002 in the correspondence management data 901.

  Each correspondence data 1002 includes a display code 1011, an image ID 1012, text data 1013, a display position 1014, an image deletion flag 1015, and the like. The display code 1011 is a display code. This display code is the same as the display code 212 of the above-described sign information 201 and the display code 311 of the display content data 302. The image ID 1012 and the text data 1013 are image identification information and text data displayed on the display device 112 when the display code 1011 included in the same correspondence data 1002 is input. A display position 1014 indicates the display position on the display device 112 of the image with the image ID 1012 included in the same correspondence data 1002. The image deletion flag 1015 indicates whether or not to delete the image with the image ID 1012 and the text data 1013 included in the same correspondence data 1002 when an image from the navigation system 14 is input. In the example of FIG. 10, the image deletion flag 1015 “0” indicates that deletion is not performed, and the image deletion flag 1015 “1” indicates deletion.

  In the example of FIG. 10, when there is no need to display image or text data on the icon display in each correspondence data 1002, the image ID 1012 and text data 1013 included in the correspondence data 1002 are indicated by “NULL”. .

  Next, an example of the image management data 902 will be described with reference to FIG.

  In FIG. 11, the image management data 902 includes one display image number 1101, a plurality of display image elements 1102, and the like. Here, display image elements 1102 are set as many as the number of images to be displayed.

  The display image number 1101 is the number of display image elements 1102 in the image management data 902. Each display image element 1102 includes an image ID 1111, image data 1112, and the like. The image ID 1111 is image identification information. The image data 1112 is image data itself.

  Next, an operation example will be described.

  Here, a sequence example will be described first, and then an operation example of each device alone will be described.

  First, a sequence example when the ECU 17 detects an abnormality will be described with reference to FIG.

  When detecting an abnormality (S1201), the abnormality detection unit 181 of the ECU 17 outputs a display code for notifying the detected abnormality to both the navigation system 14 and the icon display device 11 (S1202, S1203).

  The icon display device 11 reads out image data, text data, and the like for warning of an abnormality in the input display code from the correspondence management data 901 and the image management data 902 in the ROM 114, and displays them on the display device 112 (S1204). ).

  On the other hand, the navigation system 14 acquires display information for warning the abnormality of the input display code from the secondary storage device 142 (S1205). Next, the navigation system 14 sequentially extracts text data or image data with an earlier display order from the acquired display information (S1206), and outputs it to the icon display device 11 (S1207). The navigation system 14 repeats this data extraction and output until all of the text data and image data included in the extracted display information are output.

  When the information from the navigation system 14 is input, the icon display device 11 sequentially displays the information on the display device 112 (S1208).

  Next, an example of a sequence for displaying a road sign installed on the shoulder of the road will be described with reference to FIG.

  When the navigation system 14 acquires the position of the vehicle (S1301), the navigation system 14 performs map matching to detect a road that is running (S1302). The navigation system 14 determines whether there is a sign to be displayed on the road (S1303). If there is no sign, the process is terminated. If there is a sign, the process is continued.

  Here, when there are a plurality of corresponding signs, the navigation system 14 selects a sign to be displayed according to the priority or the like, and acquires display information of the sign (S1304).

  The navigation system 14 determines whether or not the display information acquired in S1304 is a setting for displaying text data (S1305).

  As a result of the determination in S1305, when the acquired display information is set to display text data, the navigation system 14 extracts text data to be displayed from the acquired display information and outputs it to the icon display device 11 (S1306). ).

  The icon display device 11 to which the text data has been input displays the text data on the display device 112 (S1307).

  As a result of the determination in S1305, if the acquired display information is not set to display text data, or after outputting the text data, the navigation system 14 sequentially selects image data and the like of the extracted display information (S1308), It outputs to the icon display apparatus 11 (S1309). The navigation system 14 repeats acquisition and output of this data until all image data included in the extracted display information is output.

  When the image data from the navigation system 14 is input, the icon display device 11 sequentially displays the image data on the display device 112 (S1310).

  Next, an operation example of a single device will be described.

  First, an operation example of the navigation system 14 alone will be described.

  First, referring to FIG. 14, an operation example when a display code is input from the ECU 17 will be described. This operation example corresponds to the above-described S1205 to S1207.

  As described above, when detecting an abnormality, the ECU 17 outputs a display code for notifying the detected abnormality to each of the icon display device 11 and the navigation system 14.

  In FIG. 14, the display code receiving unit 151 of the navigation system 14 receives the display code (S1401).

  The display information acquisition unit 152 acquires display information for notifying abnormality of the received display code (S1402). For this purpose, for example, the display information acquisition unit 152 refers to the display content management data 162 in the secondary storage device 142 and reads the display content data 302 including the display code 311 that matches the display code received in S1401. Further, the display information acquisition unit 152 reads the image set data 402 including the display image set ID 411 that matches the display image set ID 312 of the read display content data 302 from the image set management data 163. The display information acquisition unit 152 stores the read display content data 302, image set data 402, and the like in a predetermined area of the memory 143. Further, the display information acquisition unit 152 reads the display image element 802 including the image ID 811 that matches the image ID 421 included in each of the image attribute information 413 of each read image set data 402 from the image element management data 164, and stores the memory. 143 is stored in a predetermined area.

  Specifically, for example, a case where the display code “E00001” is received in the process of S1401 will be described. In this case, the display information acquisition unit 152 refers to the display content management data 162 shown as an example in FIG. 3 and reads the display content data 302 including the display code 311 “E00001”. Further, the display information acquisition unit 152 reads the image set data 402 including the image set ID 412 “G-001” included in the display content data 302 from the image set management data 163. The image set data 402 is an example shown in FIG.

  Here, when there are a plurality of received display codes, the display information of the display code with the highest priority may be acquired. Therefore, for example, the display information acquisition unit 152 acquires the image set data 402 for each display code by the same processing as described above, and compares the display priorities 415 included in the respective image set data 402 to obtain the priority. High display information may be specified. Further, information for determining the priority may be included in the display code, and the display information acquisition unit 152 may specify display information with a high priority from this information.

  The display information output unit 153 determines whether or not the received display code abnormality is text data display (S1403). For this purpose, for example, the display information acquisition unit 152 determines whether or not the text data 313 included in the display content data 302 read out in the process of S1402 is “NULL”.

  Specifically, for example, when the display code “E00021” is received in the process of S1401, the display information output unit 153 refers to the display content management data 162 shown in FIG. 3 as an example, and displays the display code 311 “E00021”. It is determined whether or not the text data 313 of the display content data 302 to be included is “NULL”. In the case of the example in FIG. 3, since the text data 313 “the tire on the left front wheel is puncture” and not “NULL”, the display information output unit 153 determines that the text data is to be displayed.

  If the result of the determination in S1403 is to display text data, the display information output unit 153 outputs the text data to be displayed to the icon display device 11 (S1404). For this purpose, for example, the display information output unit 153 reads the text data 313 included in the display content data 302 read out in the process of S1402 described above, and outputs it to the icon display device 11 together with the display ID received in S1401.

  Specifically, for example, as described above, when the display code “E00021” is received in the process of S1401, the display information output unit 153 refers to the display content management data 162 shown in FIG. Text data 313 “left front wheel tire is punctured” in the display content data 302 including 311 “E00021” is output to the icon display device 11.

  As a result of the determination in S1403, if the text data is not to be displayed, or after the processing in S1404, the display information output unit 153 selects image data to be displayed in order from the earliest display order (S1405). . For this purpose, the display information output unit 153 refers to each of the image attribute information 413 in the image set data 402 acquired in the above-described processing of S1402 with reference to the memory 143, for example. The display information output unit 153 selects the image attribute information 413 that has not been selected in the processing of S1405 and includes the one having the smallest display time difference 521. The image indicated by the image ID 421 in the image attribute information 413 selected here is the image data selected in S1405. Note that when there are two or more corresponding image attribute information 413, the display information output unit 153 selects the one in the display order. As described above, here, the image attribute information 413 is sorted in descending order of display order.

  Specifically, for example, as described above, an example in which the display code “E00001” is received in the process of S1401 will be described. Here, an example in which the image attribute information 413 has not been selected in the processing of S1405 will be described. Each of the image attribute information 413 in this case shows an example in FIG. In the example of FIG. 5, the smallest display time difference 521 is “0 s”. Since there are two corresponding ones including the image ID 421 “1001” and one including the image ID 421 “1002”, the display information output unit 153 is in the area where the display information acquired by the memory 143 is stored. The image data of the image ID 421 “1001” of the image attribute information 413 with the earlier display order is selected.

  The display information output unit 153 outputs the image data selected in S1405 to the icon display device 11 (S1406). For this purpose, the display information output unit 153 displays a display image element 802 including an image ID 811 that matches the image ID 512 included in the image attribute information 413 selected in S1405 from the area where the acquired display information is stored in the memory 143. select. The display information output unit 153 includes the image attribute information 413 selected in S1405, the image data 812 included in the selected display image element 802, the animation information 414 included in the image set data 402 read out in the above-described processing of S1402, and the like. The display code or the like received in is output to the icon display device 11. Here, after the output to the icon display device 11 is completed, the display information output unit 153 starts the image attribute information 413, the display image element 802, and the image attribute information 413 output this time from the area storing the acquired display information in the memory 143. The animation information 414 and the like may be deleted.

  Note that if the information is output for the second time or later in the process of S1406, the display information output unit 153 may not output the animation information 414.

  In addition, when the information is output for the second time or later in the process of S1406 and image data with the same image ID has been output before, the display information output unit 153 does not output the image data. good.

  Next, the display information output unit 153 determines whether all information has been output (S1407). For this purpose, for example, the display information output unit 153 determines whether or not all of the image attribute information 413 in the area storing the acquired display information in the memory 143 has been selected in the above-described processing of S1405.

  If all the information is not output as a result of the determination in S1407, the display information output unit 153 performs the processes in S1405 and subsequent steps again.

  If all the information is output as a result of the determination in S1407, the display information output unit 153 ends the process.

  Next, with reference to FIG. 15, an operation example in the case where the presence / absence of a sign is detected and displayed will be described. This operation example corresponds to S1301 to S1304 described above.

  The own vehicle position acquisition unit 154 of the navigation system 14 acquires the current position of the vehicle from the information acquired from the position measurement device 144 (S1501). This process is the same as the navigation system of the prior art, and is not particularly limited, so the description is omitted.

  The map match processing unit 155 performs a map match from the current position acquired in S1501 (S1502). That is, the map match processing unit 155 acquires from the map data 161 where the current position is located on the map, more specifically, on which road the vehicle is traveling. Since this map matching process is the same as the navigation system of the prior art, detailed description is omitted.

  The determination unit 156 determines whether there is a sign within a predetermined range from the current position (S1503). Therefore, the determination unit 156 refers to the position 211 of each line of the sign information 201, is located on the road on which the vehicle travels acquired in S1502, and is within a predetermined range from the current position with respect to the traveling direction of the vehicle. It is determined whether or not what is located is included.

  If there is no sign as a result of the determination in S1503, the determination unit 156 ends the process.

  As a result of the determination in S1503, when there is a sign, the determination unit 156 selects the corresponding signs in descending order of priority (S1504). Therefore, the determination unit 156 reads the display code 212 of the line including the position 211 determined to be applicable in the processing of S1503 described above from the sign information 201. When there is a corresponding sign, the determination unit 156 performs this process for each sign. The determination unit 156 selects the display content data 302 including the display code 311 that matches each read display code 212 from the display content management data 162, and reads the display image set ID 312 included in the display content data 302. Next, the determination unit 156 selects the image set data 402 including the display image set ID 411 that matches the read display image set ID 312 from the image set management data 163. The determination unit 156 reads the display priority 415 from each selected image set data 402. The determination unit 156 reads the display priority 415 for each corresponding indicator. The determination unit 156 selects a label with the highest priority among the read display priorities 415.

  The determination unit 156 instructs display processing of the sign selected in S1504. The display information acquisition unit 152 and the like perform display instruction processing for the selected sign according to this instruction (S1505). This processing example is the operation described with reference to FIG. 14 described above except that the display code is input from the ECU 17 or the display code of the sign selected by the navigation system 14 itself. Since it is the same as an example, description is abbreviate | omitted.

  Here, the display information output unit 153 may change the output process according to the type of the sign when outputting text data and image data for notifying the sign to the icon display device 11. That is, if the sign to be output is a warning sign such as “with crossing”, the display information output unit 153 outputs the text data and the image data in the operation example described with reference to FIG. If it is something other than a warning sign, both text data and image data may be output simultaneously. For example, information indicating the label type of the display code 212 in the same line is added to each line of the label information 201 in advance, and the display information output unit 153 corresponds to the label type in the process of S1503 described above. Then, the determination may be made by referring to the label type of the line including the determined position 211.

  Next, an operation example of the icon display device 11 alone will be described.

  First, with reference to FIG. 16, an operation example of displaying display information stored therein when a display code from the ECU 17 is input will be described. Note that this operation example corresponds to the above-described S1204 and the like.

  In FIG. 16, the display code receiving unit 121 of the icon display device 11 receives a display code from the ECU 17 (S1601). Here, the display code receiving unit 121 may perform an image source switching process. That is, when the display code is received, if at least one of the display code notifying other abnormality from the EUC 17 and the display code notifying the sign from the navigation system 14 is already received, It may be determined whether to display any of them. For this determination criterion, for example, a table (not shown) in which display priorities are set in advance may be referred to, and the display code may include information serving as the determination criterion.

  Next, the display information acquisition unit 122 acquires display information stored therein (S1602). For this purpose, the display information acquisition unit 122 extracts correspondence data 1002 including the display code 1011 that matches the display code received in S1601 from the correspondence management data 901 in the ROM 114, for example. Next, the display information acquisition unit 122 extracts the image ID 1012 from the extracted correspondence data 1002. The processing unit 112 reads a display image element 1102 including an image ID 1111 that matches the extracted image ID 1012 from the image management data 902.

  Specifically, for example, a case where the display code “E00001” is received in the process of S1601 will be described. In this case, the display information acquisition unit 152 reads the correspondence data 1002 including the display code 1011 “E00001” with reference to the correspondence management data 901 shown in FIG. Furthermore, the display information acquisition unit 152 reads the display image element 1102 including the image ID 11112 “i001” included in the read correspondence data 1002 from the table 1103 illustrated in FIG.

  The display information output unit 123 causes the display device 112 to display the display information acquired in S1602 (S1603). For this purpose, for example, the display information output unit 123 extracts the text data 1013 from the correspondence data 1002 read in S1602 and displays the text data 1013 at a predetermined position on the display device 112. Further, the display information output unit 123 extracts the display position 1014 from the correspondence data 1002 read in S1602, and extracts the image data 1112 from the display image element 1102 read in S1602. The display information output unit 123 causes the display device 112 to display the extracted image data 1112 at the extracted display position 1014.

  Specifically, for example, when the display code “E00001” is received in the process of S1601, the display information acquisition unit 152 reads the text from the correspondence relationship data 1002 including the display code 1011 “E00001” as shown in FIG. Data 1013 “engine failure” is extracted and displayed at a predetermined position on the display device 112. The display information acquisition unit 152 extracts the display position 1014 “(10, 10)” from the same correspondence data 1002. Furthermore, the display information acquisition unit 152 extracts image data 1112 from the display image element 1102 including the image IS1211 “i001”, which is an example shown in FIG. The display information acquisition unit 152 causes the display device 112 to display the extracted image data 1112 at the extracted display position 1014 “(10, 10)”.

  Here, as described above, the navigation system 14 to which the display code from the ECU 17 is input outputs information including image data and the like. When the input of information from the navigation system 14 is received (S1604), the display information output unit 123 determines whether or not to erase already displayed information (S1605). Therefore, for example, the display information output unit 123 refers to the image erasure flag 1015 included in the correspondence data 1002 read in S1602 and determines whether or not erasure is indicated.

As a result of the determination in S1605, in the case of setting to delete already displayed information, the display information output unit 123 clears the display (S1606).
As a result of the determination in S1605, when the setting is made not to delete the already displayed information, or after the processing in S1606, the process proceeds to a display update process described later.

  Next, an operation example of the display update process will be described with reference to FIGS. This operation example corresponds to the above-described S1208, S1307, S1310, and the like.

  As described above, the navigation system 14 sequentially outputs information including text data or image data to the icon display device 11. The icon display device 11 stores the input display information in the RAM 113.

  First, with reference to FIG. 17, an operation example until text data and image data output from the navigation system 14 are first displayed will be described.

  In FIG. 17, the update unit 124 determines whether text data has been received from the information input from the navigation system 14 (S1701). Here, the text data of the input information is the text data 313 of the display content data 302 output from the navigation system 14 by the above-described processing.

  As a result of the determination in S1701, if the text data is accepted, the update unit 124 causes the display device 112 to display the text data (S1702).

  As a result of the determination in S1701, if the text data is not received, or after the processing in S1702, the update unit 124 selects a display pattern to be displayed first (S1703). As described above, the navigation system 14 outputs the image attribute information 413, the image data 812, the animation information 414, the display code, and the like in one combination. For example, the update unit 124 refers to each of the image attribute information 413 included in each of these combinations, and selects the one including the display time difference 422 “0s”. If there are multiple applicable items, select all combinations. The display pattern indicated by the image attribute information 413 included in each combination is the display pattern that is displayed first.

  The update unit 124 displays the display pattern selected in S1703 on the display device 112 (S1704). Further, the display information output unit 123 starts counting the display time of each of the cycle time and the displayed image (S1705). Here, the cycle time is indicated by a variable “Ts”, and the display time of the first displayed display pattern is indicated by a variable “T1”. In this case, the display information output unit 123 sets “Ts = 0”, “T1 = 0”, and the like, for example.

  For the same display pattern, the display time of the display pattern may be indicated by the same variable. The same display pattern means that the display time difference 422 and the display time 423 of the image attribute information 413 are the same.

  After the process of S1705 described above, the update unit 124 activates the operation of FIG.

  Next, an operation example for updating the image data to be displayed will be described with reference to FIG. Note that the operation example shown in FIG. 18 is an operation that is activated every predetermined time.

  In FIG. 18, the update unit 124 updates the cycle time and the display time of each display pattern (S1801). Specifically, the updating unit 124 sets “Ts = Ts + t” and “T1 = T2 + t”, for example. Here, “t” is a predetermined time during which the operation example shown in FIG. 18 is activated. In addition, when the display of a new display pattern is started by the process described later, the update unit 124 also updates the display time of the display pattern. For example, when the display time of another display pattern is indicated by a variable “T2”, the updating unit 124 sets “T2 = T2 + t”. Hereinafter, the display time of each display pattern is collectively referred to as “Tn”.

  The update unit 124 determines whether there is any display pattern for which the display time has elapsed (S1802). For this purpose, for example, the updating unit 124 selects one displayed display pattern, and compares the display time 423 included in the image attribute information 413 of the display pattern with the display time “Tn” of the display pattern. To do. As a result of the comparison, when the display time “Tn” is equal to or greater than the value of the display time 423, the update unit 124 determines that the display time of the display pattern has elapsed. The updating unit 124 performs this process for all the displayed display patterns.

  If there is a display pattern for which the display time has passed as a result of the determination in S1802, the updating unit 124 deletes the image data of the display pattern and clears the display time “Tn” of the display pattern (S1803). .

  As a result of the determination in S1802, when there is no display pattern for which the display time has elapsed, or after the processing in S1803, the update unit 124 displays the display start time among the display patterns of each combination output from the navigation system 14. It is determined whether or not there is any (S1804). For this purpose, the update unit 124 compares the display time difference 422 included in the image attribute information 413 of each combination with the cycle time “Ts”. As a result of this comparison, when there is a match between the display time difference 422 and the cycle time “Ts”, it is determined that the display pattern of the combination including the display time difference 422 is the display start time. The update unit 124 performs this process for all combinations input from the navigation system 14.

  If there is a display pattern that has reached the display start time as a result of the determination in S1804, the updating unit 124 starts displaying the image data of the display pattern and starts counting the display time of the display pattern (S1805). . For this purpose, for example, the update unit 124 extracts the image data 812 from the combination including the display pattern determined to have reached the display start time in the determination in S1804 described above, and causes the display device 112 to display the image data. Further, the updating unit 124 initializes a variable “Tn” for counting the display time of the display pattern, and sets “Tn = 0”. Specifically, for example, when the display pattern display time variables “T1” and “T2” are set in the processing step of S1805, the updating unit 124 sets the display time display variable of the new display pattern. It is assumed that “T3” and “T3 = 0”.

  If there is no display pattern that has reached the display start time as a result of the determination in S1804, or after the processing in S1805, the updating unit 124 determines whether or not the display is set to be repeatedly displayed (S1806). For this purpose, for example, the update unit 124 refers to the repetition 431 included in the animation information 414 input from the navigation system 14 and determines whether or not there is a repeated display.

  As a result of the determination in S1806, when it is not set to repeatedly display, the updating unit 124 ends this display processing. The icon display device 11 erases the displayed image, text, and the like when a command for instructing to stop the display is input.

  As a result of the determination in S1806, when it is set to repeatedly display, the update unit 124 determines whether or not the time from the start of display of the first display pattern has become a period time (S1807). For this purpose, for example, the updating unit 124 compares the period 432 included in the animation information 414 input from the navigation system 14 with the period time “Ts”. As a result of this comparison, when the cycle time “Ts” is equal to or greater than the value of the cycle 432, the update unit 124 determines that the time from the start of display of the first display pattern has become the cycle time.

  As a result of the determination in S1807, when the time from the start of display of the first display pattern is the cycle time, the updating unit 124 initializes the cycle time “Ts” and the display time “Tn” of each display pattern ( S1808). Therefore, the updating unit 124 sets “Ts = 0”, “Tn = 0”, and the like, for example.

  As a result of the determination in S1807, when the time from the start of display of the first display pattern is not a periodic time, or after the processing in S1808 described above, the updating unit 124 ends the current processing and a predetermined time has elapsed. Later, the processing after S1801 is performed again.

  After displaying a warning or the like as described above, the icon display device 11 clears the display on the display device 112 when a command for stopping the warning display is input or when the engine is stopped or the like. The information input from the navigation system 14 is deleted.

  Here, an example of the appearance of the icon display device 11 in the vicinity of the display device 112 will be described with reference to FIG.

  In FIG. 19, the display device 112 is located between a vehicle speed meter display area 1901 and an engine speed meter display area 1902. An audio information display area 1903 is provided above the display area 1905 displayed by the display device 112. A shift lever position information display area 1904 is provided below the display area 1905.

  Next, an example of screen transition of the display device 112 of the icon display device 11 will be described.

  First, an example of screen transition when the ECU 17 detects an abnormality “engine failure” will be described with reference to FIGS. 20 and 21. In this case, the ECU 17 outputs a display code “E00001” to each of the icon display device 11 and the navigation system 14.

  FIG. 20 is an example of screen transition while the icon display device 11 performs the operations of FIGS. 16 and 17 described above.

The icon display device 11 performs a normal display (S2001). When a display code for notifying the occurrence of an abnormality is input, the icon display device 11 extracts an image for notifying the abnormality from the ROM 114 and displays the image on the display device 112 (S2002). As described above, in the example of the correspondence management data 901 shown in FIG. 10, the text data for notifying “engine abnormality” in the icon display device 11 is the correspondence data 1002 including the display code 1011 “E00001”. The text data 1013 is “engine failure”. Further, in the example of the image management data 902 shown in FIG. 11, the image data for notifying “engine abnormality” in the icon display device 11 is the image data with the image ID 1111 “i001”. The icon display device 11 displays this image data on the display device 112. Further, the icon display device 11 displays text data 1013 “engine failure” read from the correspondence management data 901 on the display device 112 (S2003).

  Here, as described above, when the code for notifying the occurrence of abnormality is input and the text data notifying the abnormality exists, the navigation system 14 first outputs the text data to the icon display device 11. Next, the image data notifying the abnormality is sequentially output to the icon display device 11. In the case of “engine failure”, the navigation system 14 does not output text data but outputs only image data.

  Next, when display information including image data (hereinafter referred to as image data 1) is input from the navigation system 14, the icon display device 11 draws the image data 1 in the drawing buffer (S2004).

  Next, when display information including image data (hereinafter referred to as image data 2) is input from the navigation system 14, the icon display device 11 displays the image data 2 in the image data already drawn in the drawing buffer. 1 is overwritten (S2005).

  In the example shown in FIG. 4 and FIG. 5 described above, in the navigation system 14, the first output of the image data notifying “engine abnormality” is the image data (image data) of the image ID “1001”. 1), and the second output is the image data (image data 2) of the image ID “1002”. In these image data, the display time difference 422 is both “0 s”. That is, both the image data 1 with the image ID “1001” and the image data 2 with the image ID “1002” are displayed simultaneously from the beginning. Accordingly, when the drawing of the image data 2 is completed, the icon display device 11 overwrites the content of the drawing buffer on the display device 112 (S2006). Here, in the example of the correspondence management data 901 shown as an example in FIG. 10, since the image deletion flag 1015 “0” of the correspondence data 1002 including the display code 1011 “E00001” is displayed, the icon display device 11 has already displayed. The image ID 1111 “i001” displayed on the device 112 is overwritten with the image data 1 and the image data 2. The icon display device 11 sets the variable “Ts” indicating the cycle time to “Ts = 0”, further sets the variable indicating the display time of this display pattern to “T1”, and sets “T1 = 0”.

  In this way, the source for notifying abnormality or the like first is stored by itself, and a more detailed source is acquired from another device. As a result, when an abnormality occurs, a simple display can be immediately displayed, and a detailed image can be displayed thereafter.

  FIG. 21 is an example of screen transition while the icon display device 11 performs the above-described operation of FIG. The icon display device 11 also updates the times of “Ts” and “T1” during data input and drawing described below.

  On the display device 112 of the icon display device 11, the image data of the image ID “i001”, the image data 1, and the image data 2 are displayed by being overwritten by the above-described processing (S2101).

  As described above, the navigation system 14 sequentially outputs image data and the like for notifying the abnormality that has occurred to the icon display device 11. In the example shown in FIG. 4 and FIG. 5 described above, in the navigation system 14, among the image data that notifies “engine abnormality”, the third output is the image data with the image ID “1003”. The fourth output is image data with an image ID “1004”.

  When display information including image data (hereinafter referred to as image data 3) is input from the navigation system 14, the icon display device 11 draws the image data 3 in the drawing buffer (S2102).

  When display information including image data (hereinafter referred to as image data 4) is input from the navigation system 14, the icon display device 11 draws the image data 4 in the drawing buffer (S2103).

  Here, in the example shown in FIGS. 4 and 5, the display time difference 422 of the image data 3 (image data of the image ID “1003”) is “3 s”, the display time 423 is “3 s”, and the image The display time difference 422 of data 4 (image data of image ID “1004”) is “6 s”, and the display time 423 is “4 s”. In addition, the repetition 431 included in the animation information 414 indicates that there is repetition, and the period 432 is “10 s”. Accordingly, the icon display device 11 displays the image data 3 on the display device 112 after “3 s” from the start of the display of S2101 (S2005), that is, when “Ts = 3” (S2104). Further, the icon display device 11 sets “T2” as a variable indicating the display time of the display pattern of the image data 3, and sets “T2 = 0”. Thereafter, as described above, the icon display device 11 activates the operation of FIG. 18 every predetermined time, and updates each of “Ts”, “T1”, and “T2”. The icon display device 11 clears the image data 3 and the display time “T2” after “3 s” from the start of the display of S2104, that is, when “Ts = 6” and “T2 = 3”, Data 4 is displayed on the device 112 (S2105). Further, the icon display device 11 sets “T3” as a variable indicating the display time of the display pattern of the image data 4, and sets “T3 = 0”. Thereafter, as described above, the icon display device 11 activates the operation of FIG. 18 every predetermined time and updates each of “Ts”, “T1”, and “T3”.

  In the example shown in FIGS. 4 and 5, the repetition 431 included in the animation information 414 indicates that there is repetition, and the period 432 is “10 s”. Accordingly, the icon display device 11 clears the image data 4 and the display time “T3” after “4 s” from the start of the display of S2105, that is, when “Ts = 10” and “T3 = 4”. The display returns to S2103 again. The icon display device 11 sets “Ts = 0” and “T1 = 0”, and repeats the display of S2103, S2104, and S2105 by the same operation as described above.

  Next, an example of screen transition when the ECU 17 detects an abnormality “tire puncture” will be described with reference to FIG. 22. In this case, the ECU 17 outputs a display code “E00021” to each of the icon display device 11 and the navigation system 14.

  FIG. 22 shows an example of screen transition while the icon display device 11 performs the operations of FIGS. 16, 17, and 18 described above.

  The icon display device 11 performs a normal display (S2201). When the code for notifying the occurrence of an abnormality is input, the icon display device 11 extracts text data and an image for notifying the abnormality from the ROM 114, and displays them on the display device 112 (S2202). As described above, in the example of the correspondence management data 901 shown in FIG. 10, the text data for notifying “tire puncture” in the icon display device 11 is the correspondence data 1002 including the display code 1011 “E00021”. The text data 1013 is “tire is punctured”. In the example of the image management data 902 shown in FIG. 11 as an example, in the icon display device 11, the image data notifying “tire puncture” is the image data with the image ID 1111 “i021”. The icon display device 11 displays the text data and image data on the display device 112.

  Here, as described above, when the code for notifying the occurrence of abnormality is input and the text data notifying the abnormality exists, the navigation system 14 first outputs the text data to the icon display device 11. Next, the image data notifying the abnormality is sequentially output to the icon display device 11.

  When the display information including the text data from the navigation system 14 is input, the icon display device 11 displays the text data on the display device 112 (S2103).

  Next, when display information including image data (hereinafter referred to as image data 1) is input from the navigation system 14, the icon display device 11 draws the image data 1 in the drawing buffer (S2104).

  Next, when display information including image data (hereinafter referred to as image data 2) is input from the navigation system 14, the icon display device 11 draws the image data 2 in the drawing buffer (S2105).

  Next, when display information including image data (hereinafter referred to as image data 3) is input from the navigation system 14, the icon display device 11 draws the image data 3 in the drawing buffer (S2106).

  In the example shown in FIGS. 4 and 6 described above, in the navigation system 14, the image data with the image ID “2101” that is output first is the image data that notifies “tire puncture”. (Image data 1) The second output is the image data with the image ID “2102” (image data 2), and the third output is the image data with the image ID “2103” (image data 3). is there. In the example shown in FIGS. 4 and 6, the display time difference 422 of the image data with the image ID “2101” is “0 s”, and the display time 423 is “2 s”. Further, the display time difference 422 of the image data with the image ID “2102” is “2 s”, and the display time 423 is “2 s”. The display time difference 422 of the image data with the image ID “2103” is “4 s”, and the display time 423 is “2 s”. Accordingly, the icon display device 11 first displays the image data 1 on the display device 112 (S2107). Here, in the example of the correspondence management data 901 shown as an example in FIG. 10, since the image deletion flag 1015 “1” of the correspondence data 1002 including the display code 1011 “E00021” is displayed, the icon display device 11 has already displayed. The image ID 1111 “i021” displayed on the device 112 is cleared, and the image data 1 is displayed. The icon display device 11 sets the variable “Ts” indicating the cycle time to “Ts = 0”, further sets the variable indicating the display time of this display pattern to “T1”, and sets “T1 = 0”. Thereafter, as described above, the icon display device 11 activates the operation of FIG. 18 every predetermined time to update each of “Ts” and “T1”.

  The icon display device 11 clears the image data 1 and the display time “T1” after “2 s” from the start of the display of S2207, that is, when “Ts = 2” and “T1 = 2”, and the image data 2 is displayed on the display device 112 (S2208). Further, the icon display device 11 sets “T2” as a variable indicating the display time of the display pattern of the image data 2 and “T2 = 0”. Thereafter, as described above, the icon display device 11 activates the operation of FIG. 18 every predetermined time to update each of “Ts” and “T2”.

  The icon display device 11 clears the image data 2 and the display time “T2” after “2s” from the start of the display of S2208, that is, when “Ts = 4” and “T2 = 2”, and the image data 3 is displayed on the device 112 (S2209). Further, the icon display device 11 sets “T3” as a variable indicating the display time of the display pattern of the image data 3 and “T3 = 0”. Thereafter, as described above, the icon display device 11 activates the operation of FIG. 18 every predetermined time to update each of “Ts” and “T3”.

  In the example shown in FIGS. 4 and 6, the repetition 431 included in the animation information 414 indicates that there is a repetition, and the period 432 is “6s”. Accordingly, the icon display device 11 clears the image data 3 and the display time “T3” after “2 s” from the start of the display in S2209, that is, when “Ts = 6” and “T3 = 2”. The display returns to S2207 again. The icon display device 11 sets “Ts = 0” and “T1 = 0” and repeats the display of S2207, S2208, and S2209 by the same operation as described above.

  Next, an example of screen transition when the ECU 17 detects an abnormality “decrease in tire air pressure” will be described with reference to FIG. In this case, the ECU 17 outputs a display code “E00022” to each of the icon display device 11 and the navigation system 14.

  FIG. 23 shows an example of screen transition while the icon display device 11 performs the operations of FIGS. 16, 17, and 18 described above.

  The icon display device 11 performs a normal display (S2301). When a code for notifying the occurrence of an abnormality is input, the icon display device 11 extracts text data and an image for notifying the abnormality from the ROM 114, and displays them on the display device 112 (S2302). As described above, in the example of the correspondence management data 901 shown as an example in FIG. 10, the text data informing the “tire pressure reduction” in the icon display device 11 is the correspondence data 1002 including the display code 1011 “E00022”. Is the text data 1013 of “tire pressure reduction”. In the example of the image management data 902 shown in FIG. 11, the image data for notifying “decrease in tire air pressure” in the icon display device 11 is the image data with the image ID 1111 “i021”. The icon display device 11 displays the text data and image data on the display device 112.

  Here, as described above, when the code for notifying the occurrence of abnormality is input and the text data notifying the abnormality exists, the navigation system 14 first outputs the text data to the icon display device 11. Next, the image data notifying the abnormality is sequentially output to the icon display device 11.

  When the display information including the text data from the navigation system 14 is input, the icon display device 11 displays the text data on the display device 112 (S2303).

  Next, when display information including image data (hereinafter referred to as image data 1) is input from the navigation system 14, the icon display device 11 draws the image data 1 in the drawing buffer (S2304).

  Here, in the example shown in FIG. 4 and FIG. 7 described above, in the navigation system 14, the image data with the image ID “2101” that is output first is the image data that notifies “decrease in tire air pressure”. It is data. 4 and 7, the image data of the image ID “2101” is displayed with a display time difference 422 “0 s”, a display time 423 “1 s”, and a display position 424 “(20, 20)”. Image attribute information to be displayed, display time difference 422 “1s”, display time 423 “1s”, and image attribute information to be displayed at display position 424 “(20, 40)”. Since the image attribute information is sorted in the display order as described above, the image attribute information including the display position 424 “(20, 20)” is displayed first, and the display position 424 “(20, 40) is displayed. ) ”Will be displayed later. Accordingly, the icon display device 11 displays the image data 1 with the image ID “2101” on the display device 112 so as to be at the display position 424 “(20, 20)” (S2105). Here, in the example of the correspondence management data 901 shown as an example in FIG. 10, since the image deletion flag 1015 “1” of the correspondence data 1002 including the display code 1011 “E00022”, the icon display device 11 has already displayed. The image ID 1111 “i021” displayed on the device 112 is cleared, and the image data 1 is displayed. The icon display device 11 sets the variable “Ts” indicating the cycle time to “Ts = 0”, further sets the variable indicating the display time of this display pattern to “T1”, and sets “T1 = 0”. Thereafter, as described above, the icon display device 11 activates the operation of FIG. 18 every predetermined time to update each of “Ts” and “T1”.

  The icon display device 11 displays the image data displayed at the display position 424 “(20, 20)” after “1 s” from the start of the display of S2304, that is, when “Ts = 1” and “T1 = 1”. 1 and the display time “T1” are cleared, and the image data 1 is displayed on the display device 112 so as to be the display position 424 “(20, 40)” (S2106). Further, the icon display device 11 sets “T2” as a variable indicating the display time of the display pattern of the image data 1 and “T2 = 0”. Thereafter, as described above, the icon display device 11 activates the operation of FIG. 18 every predetermined time to update each of “Ts” and “T2”.

  In the example shown in FIGS. 4 and 7, the repetition 431 included in the animation information 414 indicates that there is repetition, and the period 432 is “2s”. Therefore, the icon display device 11 displays the display position 424 “(20, 40)” after “1 s” from the start of the display of S2306, that is, when “Ts = 2” and “T2 = 1”. The image data 1 and the display time “T2” are cleared, and the display returns to S2305 again. The icon display device 11 sets “Ts = 0” and “T1 = 0” and repeats the display of S2305 and S2306.

  Next, an example of screen transition when the navigation system 14 detects a sign that exists within a predetermined range from the current position will be described with reference to FIG.

  FIG. 24 shows an example of screen transition while the icon display device 11 performs the operations of FIGS. 16, 17 and 18 described above.

  The icon display device 11 performs normal display (S2401).

  Here, as described above, the navigation system 14 detects a sign existing within a predetermined range from the current position, and when there is text data notifying the presence of the sign, the text data is first displayed as an icon display device. 11 is output. Next, image data notifying the presence of the sign is sequentially output to the icon display device 11.

  When the display information including the text data from the navigation system 14 is input, the icon display device 11 displays the text data on the display device 112 (S2402).

  Next, when display information including image data is input from the navigation system 14, the icon display device 11 displays the image data on the display device 112 (S2403). Here, since the example in which a plurality of display patterns are set as described above for the image data of the sign to be notified is the same as described above, the description is omitted.

  In this way, the source for notifying abnormality or the like first is stored by itself, and a more detailed source is acquired from another device. As a result, when an abnormality occurs, a simple display can be immediately displayed, and a detailed image can be displayed thereafter.

Also, even if you want to display image data with a large data capacity or if you want to display animations, the data to be displayed is displayed after a simple display of the requirements to be notified first. Even if it takes time before the data can be displayed, the display of the minimum information to be notified is not delayed.
<Second Embodiment>
Next, a second embodiment will be described.

  The second embodiment differs from the first embodiment described above in that the navigation system 14 stores the display information of the sign in the icon display device 11. At this time, the navigation system 14 acquires the free capacity of the storage device of the icon display device 11, and stores the display information of the sign only for the data that can be stored in the storage device. Hereinafter, the same reference numerals are given to the same components as those in the first embodiment, and the description thereof is omitted.

  First, a configuration example of the second embodiment will be described with reference to FIG.

  In FIG. 25, the difference from the first embodiment described above is that the icon display device 11 further includes a free capacity providing unit 2501 and a display information output unit 2502 instead of the display information acquisition unit 122. The navigation system 14 further includes a free capacity acquisition unit 2511 and a display information output unit 2512 instead of the display information output unit 153. The navigation system 14 further includes free capacity management data 2521 and output information management data 2522.

  The free space acquisition unit 2511 of the navigation system 14 requests the free space of the RAM 113 from the icon display device 11. Further, the display information output unit 2512 outputs the display information of the sign to the icon display device 11 according to the free space of the RAM 113.

  The free space providing unit 2501 of the icon display device 11 acquires the free space in the RAM 113 in accordance with a request from the navigation system 14 and outputs the free space to the navigation system 14. The display information output unit 2502 stores the display information from the navigation system 14 in the RAM 113. The display information output unit 2502 acquires text data, image data, and the like for notifying the sign from the RAM 113.

  The free capacity management data 2521 stores the free capacity of the RAM 113 acquired from the icon display device 11. In the output information management data 2522, the display code of the sign stored in the RAM 113 is stored.

  Note that the RAM 113 of the second embodiment may or may not hold the stored contents even when the power is turned off. When the RAM 113 is non-existent, the processing described below may be performed only once when the navigation system 14 is activated for the first time.

  Next, an operation example will be described.

  First, a sequence example in which the navigation system 14 outputs and stores sign display information will be described with reference to FIG.

  The free space acquisition unit 2511 of the navigation system 14 requests the free space of the RAM 113 from the icon display device 11 (S2601).

  Upon receiving this request, the free space providing unit 2501 of the icon display device 11 acquires the free space of the RAM 113 (S2602), and outputs the acquired free space to the navigation system 14 (S2603).

  The free space acquisition unit 2511 of the navigation system 14 stores the input free space in the free space management data 2521.

  Next, the display information output unit 2512 of the navigation system 14 sorts the display information of the signs in descending order of priority (S2604). For this purpose, for example, the display information output unit 2512 selects, from among the image set data 402 in the image set management data 163 of the secondary storage device 142, the one that stores the marker information. In order to determine whether or not each image set data 402 stores sign information, for example, a flag indicating whether or not each image set data 402 stores sign information is provided in advance. It may be determined by this flag. Next, the display information output unit 2512 sorts the image set data 402 in descending order of priority based on the display priority 415 included in each of the selected image set data 402.

  The display information output unit 2512 determines whether or not the free space of the RAM 113 in the free space management data 2521 is equal to or greater than a predetermined value (S2605). This predetermined value may be arbitrary, and may be a value that can be determined to be sufficient for storing display information, such as “0”, for example. Further, the data amount of the display information acquired in the process of S2606 described below may be set as a predetermined value.

  As a result of the determination in S2605, when the free space is equal to or larger than the predetermined value, the display information output unit 2512 selects one of the image set data 402 sorted in the process of S2604 from the highest priority and selects the selected image. Display information of the set data 402 is acquired (S2606) and output to the icon display device 11 (S2607). For this purpose, for example, the display information output unit 2512 extracts the display image set ID 411 from the image set data 402 selected one in descending order of priority. The display information output unit 2512 extracts the display content data 302 including the display image set ID 312 that matches the extracted display image set ID 411 from the display content management data 162. Further, the display information output unit 2512 extracts a display image element 802 including an image ID 811 that matches each of the image IDs 421 included in each of the image attribute information 413 of the selected image set data 402 from the image element management data 164. . The display information output unit 2512 outputs the selected image set data 402, the extracted display content data 302, the display image element 802, and the like as display information to the icon display device 11.

  Further, the display information output unit 2512 updates the free capacity of the RAM 113 in the free capacity management data 2521, the display code in the output information management data 2522, and the like (S2608). Therefore, the display information output unit 2512 stores a value obtained by subtracting the data capacity of the display information output this time from the free capacity in the free capacity management data 2521 as a new free capacity in the free capacity management data 2521. Further, the display information output unit 2512 adds the display code 311 and the like included in the output display content data 302 to the output information management data 2522.

  On the other hand, the display information output unit 2502 of the icon display device 11 stores the display information transmitted from the navigation system 14 in the RAM 113 (S2609).

  The display information output unit 2512 determines whether display information of all the signs has been output (S2610).

  As a result of the determination in S2610, when the display information of all the signs has not been output, the display information output unit 2512 performs the above-described processing after S2605 again.

  If the display information of all the signs is output as a result of the determination in S2610, or if the free capacity is not equal to or greater than the predetermined value as a result of the determination in S2605, the display information output unit 2512 ends the process.

  Next, a sequence example when the navigation system 14 detects a sign to be displayed will be described with reference to FIG. Hereinafter, only operations different from those in the first embodiment will be described in detail.

  The own vehicle position acquisition unit 154 of the navigation system 14 acquires the own vehicle position (S2701). The determination unit 156 performs map matching to detect a road that is running (S2702). The navigation system 14 determines whether there is a sign to be displayed on the road (S2703).

  If the result of determination in S2703 is that there is no sign, processing is terminated.

  If there is a sign as a result of the determination in S2703, the display information output unit 2512 selects the display ID of the sign to be displayed (S2704). This operation example is the same as described above. In addition, when there are a plurality of corresponding signs, the display information output unit 2512 is the same as described above in that a sign to be displayed is selected based on the priority or the like.

  The display information output unit 2512 refers to the output information management data 2522 of the free space management data 2521, and determines whether or not a display ID that matches the display ID selected in S2704 is included (S2705).

  When the display ID of the selected sign is included as a result of the determination in S2705, the display information output unit 2512 outputs only the display ID to the icon display device 11 (S2706).

  The display information output unit 2502 of the icon display device 11 extracts display information including a display ID 411 that matches the input display ID from the RAM 113. The update unit 124 displays the extracted display information on the display device 112 (S2707). This display processing itself is the same as described above.

  As a result of the determination in S2705, the processing in the case where the display ID of the selected sign is not included is the same as described above, and will be described briefly.

  The navigation system 14 determines whether or not the selected sign is set to display text data (S2708).

  If the result of determination in S2708 is that the selected sign is set to display text data, the navigation system 14 acquires text data to be displayed from the secondary storage device 142 and outputs it to the icon display device 11 (S2709). ).

  The icon display device 11 to which the text data has been input displays the text data on the display device 112 (S2710).

  As a result of the determination in S2708, if the selected sign is not set to display text data, or after the process in S2709, the navigation system 14 sequentially extracts the image data and the like of the selected sign from the secondary storage device 142. (S2711), it outputs to the icon display device 11 (S2712). The navigation system 14 repeats such extraction and output of the image data until all information for notifying the sign is output.

  When the information from the navigation system 14 is input, the icon display device 11 sequentially displays the information on the display device 112 (S2713).

  Here, an example of screen transition of the second embodiment will be described with reference to FIG.

  In the normal state, display information including image data, text data, and the like is stored in the RAM 113 according to the above-described operation example (S2801).

  When a display ID is input from the navigation system 14, image data, text data, etc. are extracted from the RAM 113 based on the display ID and displayed on the display device 112 (S2802).

  This makes it possible to immediately display a warning sign image that requires urgency.

  Here, in general, the storage device of the icon display has a small capacity due to a cost problem. Therefore, the conventional icon display can only perform simple display such as displaying only one image. Therefore, according to the above-described embodiment, even if the capacity of the storage device is small, it is possible to display decorative information for the purpose of wearing the icon display. Moreover, according to this embodiment, it becomes easy to display the detailed information regarding a failure.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design changes and the like within a scope not departing from the gist of the present invention.

  For example, in the above-described embodiment, an example in which animation information is not set for a sign has been described. However, the present invention is not limited to this. Animation information may also be set for the sign.

  Further, for example, in the above-described embodiment, only the case of notifying a vehicle abnormality, a sign, or the like has been described, but the information displayed on the icon display is not limited thereto. For example, you may notify arbitrary information, such as an accident vehicle attention and the occurrence of traffic jams.
