Description

The present invention displays information such as the destination to be reached in a navigation device that assists the movement of the moving object by displaying the route of the moving object such as a vehicle and the names of famous features in the vicinity of the route together with a map. It belongs to the technical field of information retrieval devices for retrieval.

  Currently, for example, as a positioning device for various mobile objects such as vehicles, aircrafts, ships, etc., a position mark (indicator indicating the position of the mobile object at the point on the map including the point where the mobile object currently exists ) And a navigation device that guides a route to a destination point based on this is known. Among these navigation devices, vehicle navigation devices mounted on a vehicle are roughly classified into a self-supporting navigation device and a GPS (Global Positioning System) type navigation device.

  The former calculates the moving direction and moving distance of the moving body by a self-supporting sensor such as a speed sensor and an angular velocity sensor provided in the moving body, sequentially adds them to the reference point, calculates the current position, and calculates the current position. Based on this, the position mark and the corresponding map are displayed on the display screen.

  The latter receives positioning radio waves from a plurality of GPS satellites launched in outer space with a GPS receiver, and calculates the current position of the moving object by a three-dimensional survey method or a two-dimensional survey method based on the reception result. Then, based on the calculated current position, the position mark and the corresponding map are displayed on the display screen.

  More recently, so-called hybrid type vehicle navigation devices having both the functions of the above-mentioned self-supporting type and GPS type are becoming common.

  Further, in each of the above vehicle navigation devices, a device that can superimpose a route on which a vehicle is scheduled to travel on a map and display it along with famous features on the route is also generalized.

  According to each of the vehicle navigation devices described above, the user (driver) can be ascertained by associating his / her current position with a map in the vicinity of the current position. You can reach your destination without any problems.

  On the other hand, in the conventional vehicle navigation device, for example, a destination point to be reached may be set and a driving route may be calculated after a destination route to the destination point is calculated in advance. When setting the destination point, there are some which have a function of hierarchically combining a plurality of point candidates for setting the destination point and setting the destination point sequentially in the hierarchy in an interactive manner with the user.

  That is, according to the vehicle navigation device having the destination setting function, when setting the destination specifically, for example, first, the attribute name of the destination (for example, the destination name such as a golf course, a theme park, a restaurant, etc.) The attribute name indicating the type (the point candidate hierarchy constituted by the attribute name is defined as the first hierarchy) is displayed, and when the destination attribute to which the destination point belongs is selected, A plurality of prefecture names where the facilities having attributes exist (the candidate hierarchy consisting of the prefecture names is defined as the second hierarchy) are displayed, and the destination prefecture name where the destination point is located is displayed. When selected, next, a plurality of area names in the target prefecture (for example, area names in the north, south, etc .. The candidate layer containing the area name is defined as the third hierarchy) are displayed. Point exists To select the desired region name that. Next, a plurality of names of cities, towns and villages existing in the destination area (fourth layer is defined as a candidate point including the name of the municipality), and a destination city where the target point exists is selected from among them. . Finally, a plurality of specific facility names that have the previously selected purpose attribute in the selected municipality are displayed as destination point candidates, and the purpose is selected from the displayed facility names. It is possible to finally set by selecting a point.

  However, when the destination point setting function of the vehicle navigation apparatus described above is used, for example, in order to select a prefecture name included in the second hierarchy, the driver displays a desired prefecture name. There is a problem that it is necessary to perform the switching operation of the displayed prefecture name, and it takes unnecessary time to search for the target prefecture name.

  The problem is that, in a vehicle navigation apparatus capable of inputting information using a speech recognition function that has been put into practical use in recent years, all candidate prefecture names are output by voice until a desired prefecture name is selected. As a result, unnecessary time becomes longer and unnecessary sound is heard a plurality of times, which impedes driving operations.

  Furthermore, according to the above-described conventional destination point setting function, it is necessary to always start selecting candidates from the first layer. In this case, for example, the name of the municipality where the destination point exists (belonging to the fourth layer) If the user knows in advance, the selection operation must be started from the first layer, which originally does not require the selection operation. Even at this time, an unnecessary selection operation is required. It was.

  Therefore, the present invention has been made in view of the above-described problems, and the problem is that a map search device, a map search method, and the like that can search for desired information conveniently and the map search program are provided. Is to provide a recording medium on which is recorded.

Information indicating that the area 73 should be accessed in order to wait for voice input using is stored.

  Here, as is clear from the data structure of the recognition word W described above, the recognition word W in the hierarchy below the second hierarchy 41 is lower than the one recognition word W in the higher hierarchy. Only one recognition word W in the hierarchy is associated, and therefore, the recognition word W in the lower hierarchy is not associated with the plurality of recognition words W in the upper hierarchy. Therefore, it is not necessary to wait using all the recognition words W when waiting for voice input, and it is only necessary to wait using only the words in the lower hierarchy associated with the words selected in the upper hierarchy. .

  Note that the prompt message SM in the first hierarchy 31 can be recognized even when a voice such as “Shinagawa Ward” is input in response to the message “Please give the prefecture name” of the prompt message SM. When the voice input is awaited after the message is output, not only the recognition word W in the first hierarchy 40 corresponding to the output prompt message SM but also the recognition word W in the first hierarchy 40 that is waiting is supported. Thus, the data structure is such that only the recognition words in the second hierarchy 41, the third hierarchy 42, the fourth hierarchy 43, and the fifth hierarchy 44 having the above-described relationship can be referred to.

  Similarly, after outputting the prompt message SM in the second hierarchy 32 associated with the prompt message SM in the first hierarchy 31 previously selected from the prompt messages SM in the second hierarchy 32, the voice is output. When waiting for an input, not only the recognition word W in the second hierarchy 41 corresponding to the output reminder message SM but also the relevance corresponding to the recognition word W in the second hierarchy 41 waiting is received. The data structure is such that only the recognition words in the third hierarchy 42, the fourth hierarchy 43, and the fifth hierarchy 44 can be referred to.

  Further, among the prompt messages SM in the third hierarchy 33, the prompt message SM in the third hierarchy 33 associated with the previously selected prompt message SM in the second hierarchy 32 is output and then a voice input is awaited. In some cases, not only the recognition word W in the third hierarchy 42 corresponding to the output reminder message SM but also the fourth relation having the above-mentioned relationship corresponding to the recognition word W in the third hierarchy 42 waiting. The data structure is such that only the recognition words in the hierarchy 43 and the fifth hierarchy 44 can be referred to.

  Next, information search processing according to the present invention using the prompt message SM and the recognition word W having the data structure shown in FIG. 2 will be described with reference to the flowcharts shown in FIGS. In each flowchart, for example, “first prompting voice output” indicates that a voice corresponding to the message in the first layer 31 in the above-described prompting message SM is output. The operations shown in the respective flowcharts are operations executed under the control of the CPU 6 by reading a control program stored in the DVD-ROM disk DK.

  As shown in FIG. 3, in the information retrieval process of the embodiment, first, it is determined whether or not the vehicle navigation apparatus S has been turned on by turning on the ignition key of the vehicle or the like (step). S1). If it is not turned on (step S1; NO), it waits until it is turned on. If it is turned on (step S1; YES), next, initialization including initialization of the RAM 8 and the like is executed (step S1; NO). Step S2).

  When the information search mode is started by an input operation on the input device 10 or the like (step S3), the 0th prompt voice “How far will it go?” Is output through the speaker 23 (step S4). ).

  Next, it is determined whether or not there has been a voice input corresponding to the 0th prompting voice (hereinafter, a voice input corresponding to each prompting voice is simply referred to as a response) (step S5). (Step S5; YES), the content of the response is recognized by the voice recognition decoder 21 (Step S8), and then the hierarchy of the response content in the recognition word W is determined (Step S9). The contents of step S9 will be described later.

  On the other hand, if it is determined in step S5 that there is no response for a predetermined time set in advance (step S5; NO), then the first reminder voice “prefecture name, area code, registered address, recently searched address” , Genre, please "is output via the speaker 23 (step S6). Then, it is determined whether or not there is a response (step S7), and if there is no response for a predetermined time set in advance (step S7; NO), the information search processing is terminated assuming that the driver does not intend to perform the information search processing. If there is a response in step S7 (step S7; YES), the process proceeds to step S8 to recognize the content of the response, and the process proceeds to step S9.

  Next, the contents of the hierarchy determination in step S9 will be described with reference to FIG.

  In the hierarchy determination process in step S9, first, it is determined whether or not the response in step S5 is a phrase included in the first hierarchy 40 in the recognition word W (step S10). If it is a word within (step S10; YES), the process proceeds to step S20 described later.

  On the other hand, if it is determined in step S10 that the phrase is not included in the first hierarchy 40 (step S10; NO), the response in step S5 is a real name indicating a prefecture (for example, “Tokyo”). Or a real name such as “Kanagawa”) is determined (step S11).

  And when it is the real name which shows a prefecture (step S11; YES), it transfers to step S32 mentioned later. If it is not a real name indicating a prefecture (step S11; NO), then the response in step S5 is a real name indicating a municipality (for example, a real name such as “Shinagawa Ward” or “Yokohama City”). It is determined whether or not (step S12).

  And when it is the real name which shows a municipality (step S12; YES), it transfers to step S73 mentioned later. If it is not a real name indicating a municipality (step S12; NO), then the response in step S5 is a real name indicating a facility or place (for example, a real name such as “Tokyo Dome” or “Yokohama Stadium”). It is determined whether or not there is (step S13).

  If it is a real name indicating the facility or place (step S13; YES), then a map including the facility or place is searched to display a map where the indicated facility or place exists. Then, map data corresponding to the retrieved map is read from the DVD-ROM disc DK and displayed (step S17), and the process is terminated.

  On the other hand, if it is determined in step S13 that the response in step S5 is not a facility name or a place name (step S13; NO), then the response in step S5 is a number (number) indicating the area code in the telephone number. It is determined whether it is (for example, a number such as “03” or “045”) (step S14).

  And when it is the number which shows an area code (step S14; YES), it transfers to step S51 mentioned later. If it is not a number indicating an area code (step S14; NO), then the response in step S5 is a real name indicating a pre-registered destination (for example, “Chinatown” or “Roppongi” Or the like) (step S15).

  If it is a registered destination point name (step S15; YES), the process proceeds to step S17 to perform search and map display. If it is not a registered destination point name (step S15; NO) Next, it is determined whether or not the response in step S5 is a real name indicating a location that has been recently searched and stored (step S16).

  If it is a recently searched place (step S16; YES), the process proceeds to step S17 to perform search and map display. If it is not a searched place (step S16; NO), the process goes to step S6. Migrate and repeat the process so far.

Is determined (step S106). If it is not the word “others” (step S106; NO), the process proceeds to step S31. If it is the word “others” (step S106; YES), then it corresponds to the recently searched place. Out of the third reminder voice to be output, the second category, “●●? ▲▲? ▽▽ ?? □□? ◇◇?”, Is output via the speaker 23 (step) S107).

  Then, it is determined whether or not there is a response (step S108). If there is no response for a predetermined time set in advance (step S108; NO), the process returns to step S100 and the above-described operation is repeated.

  On the other hand, when there is a response in the determination in step S108 (step S108; YES), the speech recognition decoder 21 recognizes the response (step S109), and the above-described hierarchy determination is executed in step S31.

  As described above, according to the information search process in the vehicle navigation apparatus S of the embodiment, the hierarchy of the input voice information is determined, and the destination point is searched based on the determined hierarchy. It is possible to search for a point, or to search for a destination point while moving through a hierarchy over one or more levels.

  Further, each recognition word W belonging to the n + 1th (n is a natural number of 2 or more and 4 or less) layer is associated with only one of the recognition words W included in the nth layer. Therefore, if the recognition word W in the upper layer is different, the recognition word W candidate information in the lower layer associated with the recognition word W is also different, and various types of recognition words are used. A hierarchical structure including the word W can be formed.

  Furthermore, when it is determined that the layer to which the voice information input corresponding to the prompt message SM in the p-th layer (p is a natural number of 5 or less) belongs is the p-th layer, the voice information belonging to the p + 1-th layer is input. Next, the prompt message SM is output through the speaker 23, and the layer to which the voice information input corresponding to the prompt message SM in the p-th layer belongs is the p + q (p + q is a natural number of 4 or less) layer. When it is determined that there is, the prompt message SM for inputting the voice information belonging to the (p + q + 1) th layer is output next through the speaker 23, so that the destination point can be searched in the order of the hierarchical structure. It is also possible to search for a destination point while crossing one or a plurality of levels.

  Furthermore, when there is no input of voice information belonging to the hierarchy indicated by the output prompt message SM, a prompt message SM prompting the input of the voice information of the next lower hierarchy is output for the prompt message SM. Therefore, a desired destination point can be searched quickly in a short time.

  In addition, since the recognition word W belonging to the third hierarchy 42 corresponding to the registered address or the recently searched address is divided into two sections and output, the time required for outputting the prompt message SM once is shortened. In addition, it is possible to input desired voice information without outputting the prompt message SM corresponding to all the recognition words W belonging to one layer.

  Furthermore, since the information can be input / output by voice, the convenience of the information search process is further improved.

  Further, in the recognition word W shown in FIG. 2, for example, when one recognition word W in the first hierarchy 40 is selected, the recognition word W included in the hierarchy below the second hierarchy 41 is Since voice input is waited using only the recognition word W associated with the recognition word W in the selected first hierarchy 40, the number of recognition words W for standby can be reduced. And erroneous recognition at the time of reply recognition can be suppressed.

  Further, the use frequency of the recognition word W in each layer is recorded, and the recognition word W with higher use frequency is preferentially used for standby, or the recognition word W currently used for standby. If the word W for recognition having a content closer to is used for priority in the response recognition, the number of the recognition words W used for the response recognition can be further reduced, and erroneous recognition in the response recognition can be further reduced. Can be reduced.

  In the above-described embodiment, the case where the present invention is applied to the vehicle navigation device S has been described. However, the present invention can be applied to, for example, an aircraft navigation device or a marine navigation device.
