Description

  The present invention relates to an in-vehicle navigation device.

  As the vehicle travels, the current position is detected by GPS (Global Positioning System), etc., and the current position is displayed on a display device together with a road map, and an appropriate route from the starting point to the destination The vehicle-mounted navigation device that guides the user with a display device or a voice output device contributes to efficient and safe driving for the user.

  In-vehicle navigation devices have various functions in addition to route guidance. For example, if a predetermined location is registered in advance, a map around the location can be displayed later with a simple button operation. It is possible to set the point as a destination and perform route guidance to the destination with the same simple operation. For example, when a user finds a favorite store, the user can input the name of the store in characters, and when visiting the store later, the user can check the location on the map or perform simple operations. The in-vehicle navigation device can guide the route to the store.

  Since the key operation must be performed when using the above function in the navigation device, the user cannot record the contents to be recorded in the navigation device unless the vehicle is temporarily stopped. It was. In view of this, an information recording apparatus has been devised that has a function of making it possible to take notes of desired audio content in relation to the utterance (utterance) position (see Patent Document 1).

Where is the destination?” Please output a guidance message such as `` Please tell me '' and search information input by the user, including location information of departure and destination, desired visit time to the destination, and linkage information including the route from the departure point to the destination Along with (visit course information of the present invention), it is recorded in the memory 9 or the like (S32).

  Next, to confirm with the user whether there is a visit course that decides how to move the destination set by the user and whether there is a means of transportation after leaving the vehicle, Do you know if you want to go to the ground? The user inputs, for example, “I want to go to Event 1 and Event 2 today. Parking is a parking lot at the event venue and public transportation is used to move the event venue” by switch operation or voice. Based on the input result, “Today, go to Event 1 first, then Event 2 will always go.”, “Parking is stopped at the event parking lot, and from there to the event venue. A confirmation message such as “Do you use public transportation?” Is output (S33).

  A message similar to the above may be displayed on the display 10, and the user may input a visiting course or a transportation means after leaving the vehicle by operating the operation switch group 7, the remote control terminal 12, or the touch panel 22.

  When the user responds to the confirmation message and then continues the search operation for other destinations, the above-described steps S32 and S33 are repeated, and the search candidate is added and the visit candidate as the basis of the impression inquiry information. A land list is created (S34).

  When the user leaves the vehicle (S35: Yes), the current position at that time is acquired from the position detector 1, the current date and time information of the present invention is acquired from the clock IC 88, and each of the memories 9 is predetermined. (S36).

As a method for determining whether or not the user has left the vehicle, any of the following methods may be used in addition to the method for determining by the presence or absence of an occupant by the occupant detection unit 36 that is a seating sensor.
(1) When it is detected in the in-vehicle image taken by the in-vehicle camera 33 that there is no user from the driver's seat, it is determined that the user has left the vehicle.
(2) When it is detected that an ignition switch (not shown) has changed from an on state to an off state, it is determined that the user has left the vehicle.
(3) A smart key system in which the vehicle 101 authenticates the user (smart key) by wireless communication between the smart key of the user and the control unit in the vehicle, and performs door lock / unlock control based on the authentication result. When it is detected that the door lock control is performed, it is determined that the user has left the vehicle.
(4) Using a proximity sensor such as an infrared sensor (not shown) and detecting that the user is moving away from the vehicle 101, it is determined that the user has left the vehicle.

  Then, the candidate visit sites within the predetermined range from the current position of the vehicle 101 are extracted from the candidate visit site list created above and stored in a predetermined area of the memory 9 (S37). At this time, it sorts in the order close to the current position of the vehicle 101 or in the order that the user likes (that is, the order of preference and the degree of preference will be described later). Further, when the guide route is known, a candidate visit site on the guide route or within a predetermined range from the guide route may be extracted.

  And the measurement of the leaving time when the user is away from the vehicle 101 is started (S38). While the vehicle leaving time is being measured, the display device 10 is turned off, or the operation of the HDD 21 is stopped, and the mode is shifted to the power saving mode (S39).

Next, it is determined whether or not the user has returned to the vehicle 101. As a detection method, any of the following methods may be used in addition to the method of determining by the presence or absence of an occupant by the occupant detection unit 36 that is a seating sensor.
(1) In the in-vehicle image captured by the in-vehicle camera 33, when it is detected that there is no user in the driver's seat, it is determined that the user has returned.
(2) When it is detected that an ignition switch (not shown) has changed from the off state to the on state, it is determined that the user has returned.
(3) When the vehicle 101 is equipped with a smart key system, it is determined that the user has returned when it is detected that door unlock control has been performed.
(4) Using a proximity sensor such as an infrared sensor (not shown) and detecting that the user has approached the vehicle 101, it is determined that the user has returned.

  When the user returns to the vehicle 101 (S40: Yes), the process proceeds to step S41 in FIG. 5B. In step S41, the measurement of the leaving time is stopped, and date / time information at that time is acquired from the clock IC 88. And a user's action range is estimated as follows from a user's leaving time (S42).

  First, the display 10 or the speaker 15 outputs a message such as “Come back, I'm tired.” And confirms whether the user has moved on foot or used public transportation (S43). At this time, a message such as “Are you able to go around the course using public transportation as scheduled today?” Is output. When an operation input indicating that the user's information is the same as the visit course information input before leaving the vehicle is made (S44: Yes), the visit course, the list of candidate visit sites and the extracted candidate visit sites, the estimated user's From within the action range, for example, in order of walking closer to the current position of the vehicle, or in the order of the user's impression of the visit candidate place stored in the visit candidate place DB (see FIG. 9). The visit order is estimated, and a new candidate site list is created (S55).

  On the other hand, if the visit course of the user has not been input in advance, the distance, time, user up to the current position of the vehicle with reference to the map data 21m and the candidate site DB (see FIG. 9) A region visit candidate site list is created using the degree of preference and the like (S62, details will be described later).

  Then, an impression query list for outputting impression query information is created based on the final visit candidate site list or regional visit candidate site list created in step S55 or S62 (S56, described later).

  With reference to FIG. 6, the concept of creating a regional visit candidate site list in step S <b> 62 will be described. Even if the leaving time is the same, the user's action range varies greatly depending on the action means while leaving the car. When using public transportation such as trains and buses, you can go far away compared to walking.

  For example, if the leaving time is 1 hour, if it is all on foot, the range of about 4 km round-trip is the search range for the candidate site. On the other hand, when using a train from a station 5 minutes on foot from the current position of the vehicle (parking position), the round trip time from the current position of the vehicle to the boarding station (10 minutes) and the boarding station The range that can be reached by the time obtained by subtracting the round-trip time from the station to the disembarking station is the search range for the candidate site.

  If all the actions from the getting-off station are on foot, the round-trip boarding time is subtracted from the departure time, so the search range when getting off at station B is the search range when all are on foot without using the train It is indicated by an area B3 narrower than the area A3, and the search range when getting off at the station C is indicated by an area C3 narrower than the area B3.

  First, when the area visit candidate site list is created on the condition that only the walking from the parking point P0 of the vehicle acts, when the maximum reachable range by walking is indicated by the area A3, the area visit candidate site list is within the area A3. It is created in the order of visiting the searched points P1, P2, P3, P4, P7, P8.

  If the visited places are points P1, P4, P6, and P9 and the use of public transportation is inputted in advance, it is considered that the visit is made from a distant place. Created in order of P9 and P4 visits. Alternatively, the order of visits may be determined on the condition that the use of public transportation has priority over walking.

  In the case of FIG. 6 or when using a plurality of public transportation facilities, there are too many points that are potential visit sites. Therefore, when the user inputs which transportation means to use before the user leaves the vehicle (step S33 in FIG. 5A), candidates can be narrowed down. Further, if it is confirmed whether the user has used the public transportation means after returning (step S43 in FIG. 5B), the accuracy of the list of candidate sites for visit created before leaving the vehicle further increases.

  Returning to FIG. 5B, the change in the user's belongings is confirmed from the image photographed by the in-vehicle camera 33 and the image photographed before leaving the vehicle, and if the belongings increase (S57: Yes), confirmation of the belongings is confirmed. Processing is performed (S58). That is, as a result of the image processing in the image processing unit 89, if the place of visit can be identified from a paper bag or wrapping paper, the display 10 or the speaker 15 indicates, “What you have in your hand is a container of XX? ”,“ What did you purchase? ”, And wait for the user's response input. When the user visits XX shop and inputs a response indicating that △△ is bought (S59: Yes), it is assumed that the additional contents of the belonging can be associated with the visited place, and the contents are set as the candidate for visit. Record in the local DB (see FIG. 9). At this time, it may be determined that the customer has made a purchase because the impression is good, and the visited place may not be included in the impression inquiry list.

  In addition, when a well-known RFID (Radio Frequency IDentification) tag is attached to the purchased item, the communication unit 25 is configured to be able to perform data communication with the RFID, and the item information included in the RFID and the purchased store information are included. It is good also as a structure which acquires this and performs the property confirmation process of the said step S58. Of course, if an RFID tag is attached to the event ticket, it is possible to confirm whether or not the user has gone to the event by receiving this content.

  Then, in the impression inquiry list created as described above, the impression inquiry rank of the visited place is increased (S60). The range for raising the rank is determined in advance, for example, as two.

  On the other hand, when the additional contents of the belongings cannot be associated with the visited place (S59: No), the impression inquiry list is not changed. This completes the creation of an impression inquiry list that takes into account whether or not belongings have been added (S61), and proceeds to step S63 in FIG. 5C.

  In step S63 of FIG. 5C, according to the order of the impression inquiry list, impression inquiry information such as “How was □□ ●●?” Is output from the display 10 or the speaker 15, and the user's response is input. wait. This ●● is a facility, cultural property, special product, event, etc. that represents the candidate site, which is set in the map data 21m or the candidate site DB (see Fig. 9) in association with each candidate site. is there. In the candidate site DB, it corresponds to “recommended item for candidate site”.

  If it is known in the above step S60 that the user has purchased the article at the place of visit, an impression inquiry message such as “It looks like △△ is like ...” is output. .

  When the user responds to the impression inquiry information by voice input from the microphone 31, the tone of the user's response recognized by the voice recognition unit 30 and the text data extracted from the spoken language are stored. Then, the impression of the user is estimated by comparing the tone of the voice at the time of affirmation and denial of the user stored in advance in the database 21d (S64). The tone of the voice is stored as a distribution of frequency components of the voice, for example. In addition, from the text data, a phrase that represents an impression such as “good”, “bad”, “delicious”, “taste”, and the like is searched.

  Then, when the impression of the visited place is estimated from the tone of the voice and the spoken language, a message for confirming the content is sent and a response input from the user is awaited (S65). For example, when it is estimated that the impression of the visited place is affirmative, a confirmation message such as “Are you satisfied with △△?” Is sent.

  And the impression according to a user's response input is memorize | stored in visit candidate site DB (refer FIG. 9) as follows (S66).

  If the user's response input is affirmative (S67: Yes), the impression is associated with the visited place and temporarily stored in the RAM 83 (S68). When the user's response input includes an additional word that is additional information of the present invention (S69: Yes), and the auxiliary word indicates an evaluation reason (S70: Yes), the auxiliary word is recorded as an evaluation reason. A confirmation message such as “Can I record my current impression of OO?” Is transmitted (S71). Then, the process proceeds to next Step S72.

  On the other hand, when the user's response input is negative (S67: No), the impression is associated with the visited place and temporarily stored in the RAM 83 (S75). Then, a message confirming the reason, such as “Why wasn't △ △ △ △ Δ good?” Is sent out and a response input from the user is awaited (S76).

  In the database 21d or the memory 9, response content candidates (phrases) are stored in advance. And it is used for preparation of a confirmation message according to the genre etc. of a candidate site for visit, and it can specify now whether the impression of a visit place is positive or negative.

  Even when the user's response input is affirmative (S67: Yes), when there is no supplementary word (S69: No), or when the supplementary word does not indicate the reason for evaluation (S70: No) Then, the process proceeds to step S76, where a message for confirming the reason, such as “How was it?”, Is sent and a response input from the user is awaited. If there is a user response input and an incidental word (reason for evaluation) is input (step S77: No), a confirmation message such as “Can you memorize the current XX impression?” The process moves to S72. If no incidental word (evaluation reason) is input (step S77: Yes), it is checked whether there are uninquired visit candidate sites in the impression inquiry list (S78).

  In step S72, when there is a positive response to the user's response input to the confirmation message sent in step S71 or step S77: No and there is a positive response to the storage (S72: Yes), the visit of the present invention In the candidate site DB (see FIG. 9), which is also the location record database, the location information of the visited location, the visit date and time (date and time information) acquired from the clock IC 88, and the contents temporarily stored in the RAM 83 (for the visited location and its visited location) Impression) and accompanying words (reason for evaluation) are stored in association with the visited place (S73). In this way, it is recognized whether or not a visit to a specific location has occurred, and the location is registered in the candidate location DB, which is also the location registration list of the present invention, in association with the user impression reflection information.

  At this time, when user impression reflection information for the same visited place is stored in the past, and the user's impression of the visited place is positive, the preference score (see FIG. 9) of the visited candidate place DB is set. A predetermined score may be added, and if the user's visit location is negative, the predetermined score may be subtracted. In other words, the more visited places the user visits, the better the user's preference.

  On the other hand, when there is a negative response to the storage (S72: No), the process proceeds to the impression inquiry of the next candidate site for visit included in the impression inquiry list (S74 → S63).

  Impression queries are sequentially performed as described above, and when impression queries are made for all candidate visit sites included in the impression query list (S78: No), a message indicating that the impression query has been completed is output (S79). This process is terminated.

  With reference to FIG. 7, a process for creating a candidate visit site from the departure time corresponding to step S <b> 56 in FIG. 5B will be described. First, the departure time is measured from the date information when the user leaves the vehicle and the date information acquired from the clock IC 88 when returning to the vehicle 101 (S91). Next, the current position of the vehicle, that is, the parking position is read from the position detector 1 (S92). Then, referring to the candidate site list created in step S55 of FIG. 5B, the candidate site list, the candidate site DB (see FIG. 9), and the map data 21m created in step S62, the within-departure time is referred to. The visit candidate sites that the user can visit on foot are read (S93). In the example of FIG. 6, points P1, P2, P3, P4, P7, and P8 within the area A3 correspond to the candidate visit sites.

  Next, when a station or a bus stop that is within a predetermined range from the parking point, such as within a distance range that can be reciprocated on foot within the departure time from the parking position, is identified (S94: Yes), it is separated as follows. Within the vehicle time, the user searches for possible visit sites using public transportation including the specified station or bus stop. First, a public transport map is read from the map data 21m, and a station or bus stop that can make a round trip within the departure time from the station or bus stop is searched (S95). In this case, a plurality of public transport boarding times are set, and a reachable station or bus stop (specific point) is determined. In the example of FIG. 6, the station A is included in the area A3, and the stations B and C are searched as reachable stations (specific points) in consideration of the boarding time.

  Next, the searched station or bus stop (specific point) is confirmed (S96). And the range which can be reached from the specific point on foot or by other public transportation is confirmed (S97). In the example of FIG. 6, when getting off at the station B, the area C3 is reachable when getting off at the area B3 and the station C.

  In this way, a reachable range corresponding to the departure time can be set regardless of whether public transportation is used or not when leaving the vehicle (S98).

  Next, in the reachable range, the candidate site is searched, and the candidate site ranking is determined in the order of distance, for example (S99). Then, an impression inquiry list is created based on the candidate site rankings (S100, described later), and the contents are recorded in a predetermined area such as the memory 9 (S101).

  With reference to FIG. 8, the candidate visit site ranking determination process corresponding to step S <b> 100 in FIG. 7 will be described. First, the visited site list created in step S34 in FIG. 5A is referred to, and it is checked whether or not visited site information has been input before the user leaves the vehicle. If visited place information such as “I want to go to Event 1 and Event 2 today” is input (S111: Yes), it is checked whether the user's visited course information is also input before leaving the vehicle. . If the visit course information of the user is not input before leaving the vehicle (S118: No), the score of the planned visit site is set to a large value (S125).

  Next, in the candidate site DB (see FIG. 9), if there is a facility / event or the like for which a preference level (preference level score) is set for each genre (S126: Yes), it is included in the reachable range. A score corresponding to the degree of preference is set for a facility or event (S127). For facilities / events of a genre that are included in the reachable range but for which the preference level is not set (S126: No), predetermined points are set for these facilities / events (S128).

  Next, the distance from the parking position of the vehicle 101 is calculated for the above-mentioned candidate sites other than the planned site, and the distance coefficient determined in advance according to the distance is multiplied by the score according to the preference (S129). The distance coefficient is a number larger than 0 and smaller than 1, for example, and becomes a larger value as the distance from the parking position is smaller.

  Finally, based on the preference score and the sum of the set / calculated scores, the planned visit locations and the candidate visit locations are sorted in descending order of scores to create an impression inquiry list (S130). Then, this process ends. An example of the above processing will be described later with reference to FIG.

  For example, when the user's visit course information is input before leaving the vehicle, such as “parking is a parking lot at the event venue, and the event venue is moved by public transportation” (S118: Yes), the visit course. The number of scheduled visit points is set to a large value (S119).

  Next, if there is a facility / event or the like for which a preference level (preference level score) is set for each genre in the candidate site DB (see FIG. 9) (S120: Yes), it is not included in the planned visit location. A score corresponding to the degree of preference is set for a facility or event (S121). Further, for facilities / events of a genre that is on the visit course and for which the preference level is not set (S120: No), a predetermined score is set for these facilities / events (S122).

  Next, the distance to the visit course is calculated for the candidate visit site that is not on the visit course, and the above-mentioned score is multiplied by the proximity coefficient determined in accordance with the distance (S123). The proximity coefficient is a number larger than 0 and smaller than 1, for example, and becomes a larger value as the distance from the visited course is smaller.

  Finally, based on the set preference score and the sum of the set / calculated scores, the planned visit locations and the candidate visit locations are sorted in descending order of scores to create an impression inquiry list (S124). Then, this process ends. An example of the above processing will be described later with reference to FIG.

  When the visited place information is not input (S111: No), when the preference degree (preference degree score) for each genre such as the facility / event is set in the visited candidate place DB (see FIG. 9) (S112). : Yes), a score corresponding to the degree of preference is set for a facility / event included within the reachable range from the parking position (S113). For facilities / events of a genre for which no preference is set (S112: No), a predetermined score is set for these facilities / events (S114).

  Here, since there is an individual difference in the moving speed on foot, the distance between the parking position of the vehicle 101 and the candidate site for the visit is calculated, and the distance coefficient is multiplied by the user distance coefficient set for each user in advance. The score (see FIG. 10) is calculated and taken into consideration, and the candidate visit site close to the parking position of the vehicle 101 may be higher in the impression inquiry list (impression inquiry is performed sooner) (S115). .

  In addition, for users who want to complete a visit in a short time, the arrival time to the candidate site is determined based on the distance between the parking position of the vehicle 101 and the candidate site and the preset walking speed of the user. The estimated time is calculated, the arrival time coefficient score (see FIG. 10) is calculated by multiplying the arrival time by a user time coefficient set for each user in advance, and this is taken into account, and the vehicle 101 arrives in a shorter time from the parking position. Possible visit candidate sites may be higher in the impression inquiry list (impression inquiry is made sooner) (S116).

  Finally, based on the preference score and the sum of the set / calculated points, the planned visit locations and the candidate visit locations are sorted in descending order of scores to create an impression inquiry list (S117). Then, this process ends. An example of the above processing will be described later with reference to FIG.

  FIG. 9 shows an example of the visit candidate site DB stored in the database 21d. The candidate site DB is a candidate site ID “candidate site ID”, a temporary candidate site ID “temporary ID”, a candidate site name “candidate site name”, and a candidate site image. “Thumbnail (image)” that is a reduced version of the data, “Suggested site recommended items” that are representative of the candidate sites, “Nearest station (search result)” of the candidate site, “Road distance to nearest station (km)”, “Average stay time (waiting time)” at the candidate site, “Location coordinates (latitude / longitude or relative position)”, “Location option terrain data ( “Site shape, height difference) boundary (sequence)”, “preference level score (time-dependent)”, “user name (ID)”, “user score”, “user course setting number” indicating the user's preference for candidate sites "User set date that is also the visit date and time" ”Time”, “weather visit weather”, “user impression rating” given according to user impression, “user impression reason adjective” including additional information or impression information of the present invention such as good and bad, visit candidate It includes “image data” that is image data obtained by photographing the ground with the front camera 32.

  Using the example of the impression query list in FIG. 10, when it is determined No in step S <b> 111 in FIG. 8, that is, when the user has not decided on a visit place or a visit course, the impression inquiry rank determination of the candidate visit places in FIG. Will be described.

  In this case, impression inquiries are made in order of preference score. That is, first, with reference to the candidate site DB, a candidate site included in the reachable range from the parking position of the vehicle 101 is searched, and when the retrieved candidate site is included in the candidate site DB, Uses the score of the preference degree, and when it is not included in the visited candidate site DB, determines the impression inquiry rank using the score of the preference level determined in advance.

  In addition, the distance coefficient score LenP taking into account the distance coefficient set according to the distance from the parking position is calculated as LenP = 10 ÷ (distance L from the parking position to the candidate site), and added to the preference score Is described in the “Score (distance)” column. The impression inquiry rank may be determined using the “score (distance)”.

  Further, the arrival time coefficient score Tim including the arrival time coefficient set according to the arrival time from the parking position is calculated as Tim = 100 ÷ (arrival time M from the parking position to the candidate site), and the preference score What is added to is described in the “Point (Time)” column. The impression inquiry rank may be determined using the “score (time)”.

  The impression inquiry list stores arrival means to each candidate site (abbreviated as “candidate site” in FIG. 10) and a required time calculated from the distance between each candidate site from the parking position. For example, the candidate site P9 is 3.8 km from the parking position, and the required time is 2 minutes on foot from the parking position to station A, 3 minutes by public transport (train) from station A to station B, It is a 6-minute walk from station B to candidate site P9. The preference degree of the candidate site P9 is 150 points, and the impression inquiry rank is first. In addition, the distance coefficient score “point (distance)” including the distance coefficient is 153 points, and the arrival time coefficient score “point (time)” 159 points including the arrival time. 1st place.

  Using the example of the impression query list in FIG. 11, if it is determined as Yes in step S <b> 111 in FIG. 8, i.e., if the user has determined the visit place and the visit course in advance, the impression query of the visit candidate place in FIG. 6. The order determination will be described. In the example of FIG. 11, the visit course is as follows: parking position → restaurant (P4) → [walk] → ride at station A (up) → [public transport] → get off at station C (down) → [walk] → event 1 Things to see (P6) → [walking] → boarding at station C → [public transportation] → getting off at station B → [walking] → event 2 sightseeing (P9) → [walking] → boarding at station B → [public transportation] → Get off at station A → [walking] → shopping (P1) → parking position.

  Therefore, the impression inquiry list is created by extracting the above-mentioned visiting places as the visiting candidate places from the visiting candidate place DB and sorting them in the order of visiting. In addition, 300 points are set for the planned visit location on the visit course, and points are not given to other visit candidate locations. However, since the restaurant (P5) between P6 and P9 is on the visiting course, include it in the visiting course as a virtual visiting place and ask the impression that “Did you go to the usual restaurant today?” You may set to do. In addition, since the restaurant (P2) and the supermarket (P3) are also relatively close to the visit course, an impression inquiry may be made as to whether or not they have visited those stores.

  Also, the impression inquiry rank may be determined by using the distance coefficient score LenP and the arrival time coefficient score in consideration of the preference score.

  Using the impression query list example of FIG. 12, if it is determined No in step S118 in FIG. 8, that is, if the visitor has decided in advance but has not decided on the course of visit, the visit candidate in FIG. The determination of the impression order of the ground will be described. In this example, a visit place determined in advance by the user from the visit candidate place DB is extracted as a visit candidate place, 300 points are given to the visit place, and a score obtained by adding a preference score to the visit place is used. The inquiry order is determined.

  In the example of FIG. 12, the visited places are the event 1 spot (P6), the event 2 spot (P9), the restaurant (P4), and the shopping (P1), so the number of visited spots (300 points) and the preference score Is the user score, and the impression inquiry rank is determined by the user score. In addition, the number of visit points is also given for the use of public transportation (stations A, B, C) used for visiting the above-mentioned visited places.

  Also, the impression inquiry rank may be determined by using the distance coefficient score LenP and the arrival time coefficient score in consideration of the preference score.

  With reference to FIG. 13, the travel destination registration process during traveling corresponding to step S15 in FIG. 4 will be described. First, the traveling direction of the vehicle 101 is confirmed by the position detector 1 or the gyroscope 3 (S141). Next, when the user's preference score is set in the candidate site DB (there is an object of interest) (S142: Yes), the object of interest ahead of the vehicle 101 in the traveling direction is listed from the candidate site DB. Up (S143). In addition, the map data 21m that is ahead of the vehicle 101 in the traveling direction and belongs to the same genre as the object of interest is extracted.

  For example, when the distance between the current position of the vehicle and the object of interest is within a predetermined range, or when the object of interest is included in the image captured by the front camera 32, the user When it is determined that the object of interest is visible (S144: Yes), the display 10 or the speaker 15 outputs a message regarding the object of interest such as “There is OO in the left front” (S145). . Whether the user's interest in the object of interest is captured by the in-vehicle camera 33 and is subjected to image processing by the image processing unit 89 is the direction of the user's face (that is, the direction of the line of sight) is directed toward the object of interest. Alternatively, it is detected based on whether or not the object of interest is included in the in-car conversation input to the microphone 31 (S146).

  When it is determined that the user is interested in the object of interest by detecting that the object of interest is seen from the user's line of sight or conversation (S147: Yes), the display 10 or the speaker 15 An impression inquiry message such as “How is the front XX?” Is output, and a response input from the user is awaited (S148).

  At this time, when image data corresponding to the object of interest is stored in the candidate site DB, the image data may be displayed on the display screen of the display 10.

  When it is determined that the user is not interested in the object of interest (S147: No), the user's interest in the object of interest is checked until the object of interest is passed (S151: Yes) (S151: No). → S145).

  After the impression inquiry message is output in step S148, when the user inputs a response by operating the operation switch group 7 or by voice input through the microphone 31 (S149: Yes), user impression reflection information reflecting the user's impression is displayed. It memorize | stores in visit candidate site DB (S150, mentioned later).

  The user impression reflection information storage process corresponding to step S150 in FIG. 13 will be described with reference to FIG. First, the response input is converted into text data (S171). When the response input is performed by operating the operation switch group 7, for example, buttons such as “good” and “bad” are displayed on the screen of the display 10 (not shown), and are stored in advance in the database 21d or the like. The text data corresponding to the pressed button is selected. When the response input is a voice input by the microphone 31, the voice recognition unit 30 converts the voice data into text data and extracts a portion including the user impression reflection information.

  Next, the user impression reflection information converted into text data, the object of interest that has been examined by the position detector 1 for the current position of the vehicle or the presence or absence of interest, the date and time information acquired from the clock IC 88, and the candidate site DB (S172). In the candidate site DB of FIG. 9, the name of the object of interest is “candidate place name”, the position of the object of interest or the current position of the vehicle is “candidate place position coordinates”, and the user impression is “user impression reason adjective”. Reflection information is stored.

  When the “photo” button as shown in FIG. 16 displayed on the screen of the display 10 is pressed or the word “photo” is included in the audio data (S173: Yes), the front camera 32 is displayed. The object of interest is photographed (S174), and the data is stored in the “image data” of the candidate site DB (see FIG. 9) as an image of the visited site (S175). Finally, the position of the object of interest is displayed on the map screen of the display 10 (S176).

  When searching for a destination, when the user inputs a destination by voice using the microphone 31, the map data 21m is searched and the phrase stored in the “user impression reason adjective” in the candidate site DB is displayed. It may be searched whether the same content as the utterance content is included, and a candidate site for visit corresponding to the same content as the utterance content may be displayed as a destination candidate. For example, when the user utters “beautiful”, it is checked whether the word “beautiful” is stored in the “user impression reason adjective” of the visit candidate site DB, and the visit candidate site associated with “beautiful” is determined. Display as a destination candidate. Even when the user inputs the destination search keyword “beautiful” by operating the operation switch group 7 or the like, the keyword search may be performed in the candidate site DB as described above.

  The point registration list output process will be described with reference to FIG. This process is included in the navigation program 21p and is repeatedly executed together with other processes of the navigation program 21p. First, the current position of the vehicle 101 is acquired from the position detector 1 (S191). When the current position has reached a reference point such as a point within a predetermined range from the destination or home (S192: Yes), date / time information is acquired from the clock IC 88, and “user set date / time” in the candidate site DB is obtained. ”Is checked to see if there is anything (memory point) stored in the candidate site DB on that day.

  If there is something stored in the candidate site DB on that day (S193: Yes), the name of the relevant candidate site (memory point) is output to the display 10 or the speaker 15.

  At this time, the contents of the memory location are edited by operating the operation switch group 7, the remote control terminal 12, the touch panel 22 or by voice input from the microphone 31 (name change, image data addition / deletion, user evaluation change). Or the contents of the memory location may be deleted (S195).

  Further, the contents of the visit candidate site DB may be transmitted / received to / from a known personal computer (not shown) via an external network, and the contents of the visit candidate site DB may be viewed / edited on the personal computer.

  FIG. 16 shows a screen display example on the display 10 of the candidate visit site. When you click on a candidate site displayed on the map, the contents of the candidate site DB are referenced, and if there is image data corresponding to the candidate site (“XX store”), the image data is displayed in a pop-up window, for example. Display in format. At this time, when the “Impression” button on the screen is pressed, the content of “User Impression Reason Adjective” corresponding to the candidate site is output from the speaker 15 as a voice message. Alternatively, it is displayed on the display screen.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims.
