[0013]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a diagram showing an embodiment of a guide system according to the present invention, FIG. 2 is a diagram for explaining guidance start conditions, FIG. 3 is a diagram for explaining guidance points for one property,
FIG. 4 is a diagram for explaining setting of already-guided properties, and FIG. 5 is a diagram for explaining an example of guided properties.

In FIG. 1, the operation means 1 switches the map image displayed on the display output means 8 to an enlarged detailed view or a wide area view, and changes the display orientation with north facing up to the opposite orientation with south facing up. It has a key to operate for switching or switching to the map image while displaying the guidance image,
For example, a remote controller including keys as shown in FIG. 12 is used. The display output means 8 displays and outputs the guide video and map image of the property to be guided, and the voice output means 9
The guidance voice of the article to be guided is output. The map image data storage unit 2 stores map image data of roads and guide properties that are mesh-divided, and the guide data storage unit 3 displays an image that guides properties along the road, streets, and local properties. This is the one that stores audio guide data. The current position detecting means 5 detects the current position of north latitude, east longitude, running road, etc., approach direction, vehicle speed, etc. using a GPS (satellite navigation system) receiving device, vehicle speed sensor, snake angle sensor, gyro sensor, geomagnetic sensor, etc. However, it will be tracked further. The map image output means 4 reads the map image data based on the current position from the map image data storage means 2 and outputs the map image and the display signal of the approach direction. The guide output means 6 determines the current position, approach direction, vehicle speed,
The guide property is determined based on the information such as roads, the guide data is read from the guide data storage means 3, and this is converted into a video signal and a voice signal of the guide and output. The switching unit 7 switches the display output of the display output unit 8 to the map image by the map image output unit 4 or the image of the guide by the guide output unit 6, and the current position is detected by the current position detection unit 5 while traveling. Detects approach direction, vehicle speed, etc.,
Further tracking is performed, the current position and approach direction are displayed on the map image, and when the guide property is searched and the guide start point is reached, the guide output means 6 is switched to the video signal of the guide, and the video and audio are displayed. To start the guidance. Further, when the map display key of the operating means 1 is operated in this state, the guide image is switched to the map image.

In the guide system of the present invention having the above structure, when the power is turned on at ACC-ON, a title image is displayed on the screen of the display output means 8, and the power is turned off at ACC-OFF. Then, the C that stored the program when the power was turned on
If the D-ROM is set, the program is started, and if the CD-ROM is set after the power is turned on, the program is started by operating the operation means 1.
When the guide program is started, the current position is sequentially detected and tracked as the vehicle travels, and a map image displaying the approach direction arrow with the north at the center of the current position is displayed and output means 8
When the guide property is searched from the current position, the traveling direction, and the vehicle speed and the guide property is extracted from the guide data storage unit 3, the guide property is appropriately displayed.

[0016] The guide properties include facilities and buildings, spot properties such as monuments, line properties such as bridges and streets, lakes and other large-scale facilities with width, national parks and plains, and other regional zones. It can be divided into properties. For point properties, the timing of starting guidance is limited, but line properties and zone properties can be selected within a certain range. Therefore, relatively, line properties are given priority over zone properties, and point properties are given priority over line properties, and line properties and zone properties have a margin to output with delay even after priority information for important point properties is output. Can have For example, the priority may be set so that the line property or zone property is extracted when there is no point property to guide, and first, if the point property is not searched, the line property is searched, and if there is no line property. You may make it explore a zone property.

The guide retrieves the guide property stored in the guide data storage means 3 from the information such as the current position, approach direction, vehicle speed, etc., and when the vehicle approaches the guide property, the guide output means 6 automatically guides the guide property. The image and the guidance voice are output, but this guidance start is when the guide output unit 6 determines that the guidance start point set for each guidance property satisfies all the following conditions. The guidance start condition is shown in Fig. 2 (a).
When the vehicle traveling direction is within ± A ° of the guide start point approaching direction as shown in Fig. 2 and when the vehicle position is within Bm after considering the vehicle speed from the guide point coordinates as shown in Fig. 2B, It means that the property is an unvisited property and is not in the process of guiding other properties. Further, by instructing the manual guide through the operating means 1, the vicinity of the current position (vehicle) (guide start point approaching direction ± A '°, distance between guide point and current position within B'm: A' ° ≧ A
It is possible to guide any of the properties of °, B ′ ≧ B).

The guide termination condition is basically that the guide data being output is output to the end. However, when the guide stop switch is operated by the operation means 1 or when the user comes to another property guide point, If the priority of the guide unit of the property currently being guided is compared with that of the first guide unit of another property and the priority of the other property is higher, the guide unit being guided is stopped. In other words, the guide data is composed of a plurality of guide units each consisting of, for example, one image and several seconds of sound, and it is determined whether or not guidance is to be executed or canceled for each guide unit, and further, by setting a priority, When a plurality of guide properties satisfy the guide start condition, selection of execution of guide, adjustment of its length or shortness, and cancellation may be determined based on this priority.

There are a plurality of guide points for one guide property, for example, 3 as shown in FIG. 3 if they are near a T-junction.
It will have two guide points, and the position according to east longitude and north latitude and the approach direction of the vehicle will be specified. Then, among such guided properties, the properties that have been guided are stored as already-guided properties so that the same property will not be duplicated. In this case, as shown in FIG. 4, the property for which one or more guide units have finished guiding may be an already-guided property, or on condition that a predetermined high-priority guide unit has completed guiding, or for the guide unit. It may be an already announced property for each item.

Next, a specific example of guidance will be briefly described. FIG. 5 shows a situation in which a vehicle passes near the Kaminarimon gate in Asakusa. For the Kaminarimon of the guide property, for example, the guide image as shown and the guide voice of the Kaminarimon are the guide data storage means 3
It is stored in. Therefore, the guide output unit 6 searches the guide data storage unit 3 for an article satisfying the guide start condition described above based on the current position of the vehicle, the approach direction, and the vehicle speed obtained from the current position detection unit 5. And
When Kaminarimon is searched as a guide property, the guide data of the guide video and guide voice of Kaminarimon is read out, converted into each signal and output. When the guide image signal is output, the switching unit 7 outputs the guide image as shown in the figure from the display output unit 8 by switching the map image display signal from the map image output unit 4 to the guide image signal. A guidance voice such as "in Edo emotion ..." is output to the output means 9. When such guidance is completed, the guide output means 6 stores the Kaminarimon as an already-introduced property, so that even if the Kaminarimon passes through the Kaminarimon again from a different direction, it is possible to prevent redundant guidance.

However, when such property guidance is started, the current position of the vehicle, the position of the property, and the surrounding conditions of the property may not be known. In such a case, according to the present invention,
When the map key is operated by operating the map key by the operation means 1, the guide output means 6 in the switching means 7
It is possible to switch from the guide video signal by the display image signal of the map image output means 4 to the map image as shown in FIG. Although the guidance voice is output during this period, the guidance voice may be stopped. By doing so, it is possible to switch to the map image and obtain information such as the position of the property and the surrounding conditions of the property at any time even after the property guidance is started.

Further, a concrete example of the structure of the guide output means will be described.

Next, an outline of the whole operation will be described. First,
When the system is activated, the CD information storage unit 30 issues a read command to read and store the CD information from each guide CD. Then prepare for the start of the guide. When the current position information is obtained from the current position tracking unit 22, the CD information storage unit 30 issues a read command of the property data included in a predetermined area including the current position by referring to the CD information, and the property data is read. It is stored in the storage unit 32. Then, the property point extraction processing unit 31 extracts the property point data from the property point data stored in the property data storage unit 32 excluding the existing guidance information. Property exploration processor 3
3 is the property number to be guided based on the current position and approach direction from the property point data extracted by the property point extraction processing unit 31. To explore.

The guidance control processing unit 35 determines the property number. Based on this, a read command is issued to the CD drive control processing unit 27 by referring to the property address stored in the property data storage unit 32. By this read command, the guide video (compressed) and audio (compressed) data is input to the video / audio output processing unit 36 from the guide CD. The video / audio output processing unit 36 receives the guidance command from the guidance control processing unit 35 and outputs the guidance video (compressed) and audio (compressed) data to the TV.
The guide video signal of the monitor 38 and the guide audio signal of the speaker 39 are decoded and transmitted. At the same time, the guidance control processing unit 3
The guidance status is sent to 5. By sending this guidance status to the output control processing section 37 through the guidance control processing section 35, in the output control processing section 37, the video signal to the TV monitor 38 outputs the map image from the current position tracking unit 22 as the video / audio. The guide image is switched from the processing unit 36, and the guide image and the map image are switched by the map command of the remote control reception processing unit 24. Then, the video / audio output processing unit 36 notifies the guidance control processing unit 35 of the completion of each guide unit. The guidance flag of the information that has already been guided is set in the already-guided information processing section 34 by the guidance control processing section 35.

The processing flow of the entire guide system according to the present invention will be described below. First, the overall flow is shown in FIG.
It starts by turning on the power source as shown in (1) and initializes the entire apparatus (step S1). After that, an input signal from the outside is processed by a remote controller or the like (step S2), the current position is detected using various sensors, and the current position is tracked (step S3). further,
The guide property is detected according to the current position, and when there are a plurality of guide properties, which property is to be guided is determined and the guide property is output (step S4). In addition to the guidance output, a screen switching FG process during the guidance output is performed (step S5). Then, the output processing of the image / audio of the map image and the guide property is performed (step S6).

The guide property detection process in step S4 is shown in FIG.
As shown in, first, it is checked whether or not the guidance flag FG set to "1" during guidance is "1" (step S1).
1). If the guiding flag FG is not "1", the guided property is searched (step S12), and if there is a guided property, the guide data of the property is read from the CD, and the video output signal, the audio output signal, and the status signal are read. Is output, the video / audio output control processing is performed, and the guiding flag FG = 1 and the map image switching flag GDFG = 1 are set (steps S13 to S15). Then, it is checked whether or not the guidance stop key and the manual key are operated, and if not further operated, it is checked whether or not the guidance is ended (steps S16 to S18).

In the video / audio output control processing of step S15, as shown in FIG. 9, it is checked whether or not the guidance start position has passed based on the detected current position (step S3).
1) When the guide start position is passed, the guide output means 6 outputs a start voice signal, for example, a caution sound of "pawn" (step S32). Then, the video signal, the audio signal, and the status signal are output from the guide output means 6. The output voice signal is reproduced as voice guidance by the voice output means 9, and the display signal of the map image is switched to the video signal by the switching means 7 by the status signal,
The guide image is reproduced by the display output means 8. Guide flag FG = 1 and map image switching flag GDF
G = 1 is set (step S33).

If the guiding flag FG is "1" in the judgment processing of step S11, the property other than the guided property is searched (step S23), and if there is, the property has higher priority than the property being guided. Whether or not it is checked (steps S24 to S25), and if it is high, the guidance is completed up to the division of the guide unit of the property being guided (step S26), the next step S20 and subsequent steps are executed.

If it is determined in step S16 that the guidance stop key has been operated, the manual key is operated in step S17 to determine the manual mode, and if the manual mode flag MF = 1 is set (step S19), When the guidance is ended in S18, or when it is determined in step S26 that the guidance has been completed up to the division of the guide unit of the property being guided, the reproduction of the video and audio is immediately terminated and the guidance flag FG = 0 is set. It is set (step S20). At this time, if one or more guide units have been guided, the already-visited flag of the property is set (steps S21 to S22).

In the screen switching processing in step S5, as shown in FIG. 10A, for example, it is first checked whether or not property guidance is in progress (step S41). If property guidance is not in progress, time T = 0, map image is displayed. The switching flag GDFG is set to 0 (steps S48 and S49), and if the property is being guided, it is further checked whether or not the time T = 0 (step S42). When time T = 0, the map key is pressed (map command)
It is checked whether or not (step S43), if the map key is pressed, time T = a, map image switching flag GDF.
After setting G = 0 (step S44), and if the map key is not pressed, the process directly returns. If T = 0 is not set in step S42, T-1 → T is set (step S45), it is checked again whether time T = 0 (step S46), and if T = 0, After the map image switching flag GDFG = 1 is set (step S47), and if T = 0 is not established, the process immediately returns. When the map key is operated (turned on) in this way, the screen is switched by setting the flag GDFG = 0, and the property guide screen is restored after a fixed time from time T = a to T = 0.

The screen may be switched each time the map key is pressed. In this case, FIG.
As shown in (b), whether or not the property is being guided (step S5).
1) It is checked whether or not the map key is pressed (map command) (step S52). Then, if the property guide is not in progress, the map image switching flag GDFG = 0 is set (step S54). If the map key is not pressed even during the property guide, it is left as it is, and the flag GD is pressed every time the map key is pressed.
A new flag G is obtained by taking the exclusive OR of FG and "1".
By setting the value of DFG, the flag GDFG is inverted and the screen is switched (step S53). In any case, in the guide system according to the present invention, when it is desired to confirm the current position during the guidance, the map image may be switched at any time.

Then, in the video / audio output process of step S6, as shown in FIG. 11A, first, it is checked whether or not the map image switching flag GDFG = 1 (step S6).
1) If GDFG = 1, a tourist guide screen is output (step S62), and if GDFG = 1, a map screen is output (step S63). That is, only the screen is switched depending on whether or not the map image switching flag GDFG = 1. Of course, not only screen switching but also audio output may be stopped. In this case, as shown in FIG. 11B, it is checked whether or not the map image switching flag GDFG = 1 (step S71). If GDFG = 1, the tourist guide screen and voice are output (step S72). ), GDFG
If = 1 is not set, the map screen is output and the tourist guidance voice is turned off (step S73).
