The CPU 51 stores the number of passengers, the boarding date and time, the driver stored in the boarding information data area 53b. Based on the passenger's information, the destination (estimated destination) desired by the passenger is estimated from the travel schedule registered in the schedule DB 54e described later.

  The search starting point data area 53c is an area for storing vehicle position information at the time when the power of the navigation device 50 is turned on. In the main process (see FIG. 8), the CPU 51 acquires the vehicle position information at that time from the current position detection device 55 as one of initialization processes executed immediately after the power is turned on, and stores it in the search starting point data area 53c. Store.

  The position information stored in the search origin data area 53c is referred to after the estimated destination is estimated by the CPU 51 in the destination / behavior estimation process (see FIG. 12), and is estimated from the position indicated by the position information. A route to the destination is searched (see S144 in FIG. 12). That is, the position indicated by the position information stored in the search starting point data area 53c is used as the starting point position of the route search to the estimated destination.

  Here, since the position information stored in the search origin data area 53c is the position information of the vehicle at the time when the power of the navigation device 50 is turned on, the position indicated by the position information stored in the search origin data area 53c. The route search from to the estimated destination means that the route search from the starting point of the vehicle or the point where the vehicle has passed in the past to the estimated destination is performed. Then, the result of this route search is referred to in the destination / behavior suggestion process (see FIG. 13) executed by the CPU 51, and the current position of the vehicle is determined on or from the route searched in this route search. When the distance is within the range, it is determined that the vehicle is traveling toward the estimated destination.

  The route search to the estimated destination is also performed from the position (home position) indicated by the home address registered in the passenger information DB 54d described later, and the current position of the vehicle is searched by this route search. Even when the vehicle is on the route or within a predetermined distance from the route, it is determined that the vehicle is traveling toward the estimated destination.

  Then, the vehicle travels to the estimated destination based on the origin position indicated by the search origin data area 53c and the route searched from the home position indicated by the passenger information DB 54d to the estimated destination. Whether or not to display the estimated destination on the LCD 58 is determined based on the determination result. That is, when it is determined that the vehicle is traveling toward the estimated destination, the estimated destination is proposed to the passenger. On the other hand, when it is determined that the vehicle is not traveling toward the estimated destination, the estimation of the estimated destination is not executed. Therefore, the destination desired by the passenger can be proposed more accurately.

  In addition, the RAM 53 stores various flags used for each process executed by the CPU 51.

  For example, the data acquisition processing flag is a flag indicating whether or not the processing for acquiring conversation voice data and schedule book data from the mobile phone 10 is completed. If the data acquisition processing flag is on, the processing is completed. If it is off, it indicates that the processing is not completed. The data acquisition process flag is set to OFF as an initial value immediately after power-on, and the CPU 51 executes the data acquisition process (see FIG. 9) in the main process while the data acquisition process flag is OFF.

  Then, when the process of acquiring conversation voice data and schedule book data from the mobile phone 10 is executed by the data acquisition process, the data acquisition process flag is set to ON, and thereafter the data acquisition process is executed in the main process. Is skipped.

  The data update flag is a flag indicating that conversation voice data stored in a later-described conversation voice data area 54a provided in the HDD 54 or schedule book data stored in the schedule book data area 54b has been updated. If the flag is on, it indicates that these data have been updated, and if it is off, it indicates that the data has not been updated.

  This data update flag is set to OFF as an initial value immediately after the power is turned on, and the conversation voice data or schedule book data acquired from the mobile phone 10 by the data acquisition process (see FIG. 9) is stored in the conversation voice data area 54a or the schedule. When stored in the book data area 54b, the data update flag is turned on. The data update flag is referred to while the CPU 51 is executing the schedule DB update process (see FIG. 11). If the data update flag is on, the data acquisition process (see FIG. 9) performs conversation voice data area 54a or A movement schedule is estimated from each data stored in the schedule book data area 54b, and the estimated movement schedule is registered in the schedule DB 54e.

  The estimated state flag is a flag indicating the estimated state of the estimated destination. If the estimated state flag is “unestimated”, the estimated destination is not estimated. If the estimated state flag is “estimated”, the estimated state flag is estimated. It indicates that the destination has been estimated, and “re-estimation” indicates that the estimated destination needs to be estimated again. The estimated state flag is set to “unestimated” as an initial value immediately after the navigation apparatus 50 is turned on. While the estimated state flag is “unestimated”, the CPU 51 performs destination / behavior estimation in the main process. Processing (see FIG. 12) is executed.

  Then, when the estimated destination is estimated by the destination / behavior estimation process, the estimation state flag is set to “estimated”, and thereafter, the execution of the destination / action estimation process is skipped in the main process. Is done.

  On the other hand, in the guidance process (see FIG. 14) executed by the CPU 51, when the estimated destination proposed to the passenger by the destination / action proposal process (see FIG. 13) is not accepted by the passenger. The estimation state flag is set to “re-estimation”. Further, in the destination / behavior proposal process (see FIG. 13) executed by the CPU 51, the scheduled end date to the estimated destination estimated by the destination / behavior estimation process (see FIG. 12) is that of the boarding day. Even when it is determined that the vehicle is not traveling toward the estimated destination from the current vehicle position, the estimated information flag is set to “re-estimate”.

  Until the estimated state flag is set to “estimated” again by the destination / behavior estimation process (see FIG. 12), that is, until another estimated destination is estimated, the CPU 51 In the process, the destination / behavior estimation process is executed. Thereby, the navigation apparatus 50 can estimate an estimated destination again.

  The proposal processing flag is a flag indicating that the estimated estimated destination is proposed to the passenger. If the proposed processing flag is on, the estimated destination is proposed to the passenger. If it is off, it indicates that it has not been proposed. This proposal process flag is set to OFF as an initial value immediately after the navigation apparatus 50 is turned on, the CPU 51 executes a destination / action proposal process (see FIG. 13), and an estimated destination is proposed to the passenger. Then, the proposal process flag is set to ON.

  The proposal processing flag is referred to when the CPU 51 is executing the guidance processing (see FIG. 14). If the proposal processing flag is on, it is determined whether or not the passenger has accepted the estimated destination. In this case, route guidance is performed using the estimated destination as the destination. If not accepted, the CPU 51 sets the proposal processing flag to OFF in accordance with the above-described estimation state flag being set to “re-estimation”. As a result, the estimation of the estimated destination and the proposal are performed again. In the guidance process, if the proposal process flag is OFF, the route guidance to the registered destination is executed by the passenger operating the touch panel 59 and the operation key 60.

  The HDD 54 is a non-rewritable nonvolatile memory. For example, a conversation voice data area 54a and a schedule book data area 54b are provided, and a road map database (hereinafter referred to as “road map DB”) 54c, A passenger information database (hereinafter referred to as “passenger information DB”) 54d, a schedule DB 54e, and a passenger / action history database (hereinafter referred to as “passenger / action history DB”) 54f are stored.

  The conversation voice data area 54 a is an area for storing conversation voice data acquired from the mobile phone 10. The schedule book data area 54b is an area for storing schedule book data acquired from the mobile phone 10.

  The CPU 51 confirms the recording date and time of the conversation voice data already stored in the conversation voice data area 54a by executing the data acquisition process (see FIG. 9), and the conversation voice data recorded after the recording date and time. Is transmitted to the mobile phone 10 via the Bluetooth communication control circuit 56, and the conversation voice data is acquired from the mobile phone 10. The acquired conversation voice data is stored in the conversation voice data area 54a.

  Further, the CPU 51 confirms the input date and time of the schedule book data already stored in the schedule book data area 54b. If the schedule book data input after the input date and time exists in the mobile phone 10, the Bluetooth communication is performed. A request for transferring the schedule book data is transmitted to the mobile phone 10 via the control circuit 56, and the schedule book data is acquired from the mobile phone 10. Then, the acquired schedule book data is stored in the schedule book data area 54b.

  On the other hand, when the conversation voice data is newly stored in the conversation voice data area 54a by executing the schedule DB update process (see FIG. 11), the CPU 51 determines the location, date / time, and person from the conversation voice data. After the identifiable keyword is extracted by the speech recognition processor 64, the moving schedule of the vehicle is estimated. If schedule book data is newly stored in the schedule book data area 54b, the travel schedule is estimated by specifying the location, date and time, and person from the schedule described in the schedule book data. Then, the estimated movement schedule is registered in the schedule DB 54e.

  The road map DB 54c is a database storing map information for displaying various maps and roads around the current location of the vehicle and around the destination on the LCD 58, and road information used for route search to the destination.

  The passenger information DB 54d is a database in which information related to passengers in the vehicle is registered. Here, the details of the passenger information DB 54d will be described with reference to FIG. FIG. 2 is a schematic diagram schematically showing an example of the contents of the passenger information DB 54d.

  The passenger information DB 54d is mainly configured by a user information registration unit 54d1 that registers information related to the vehicle user and a passenger information registration unit 54d2 that registers information related to the vehicle passenger.

  The user information registration unit 54d1 includes “home address” information of the user (“A” in the example shown in FIG. 2) and “family” information of the user including the user A (“A” in the example shown in FIG. 2). ”,“ B ”,“ C ”) and“ driving registrant ”information (“ A ”,“ B ”in the example shown in FIG. 2) for driving the vehicle among the family members are registered. Among these, the “home address” information is referred to during the execution of the destination / behavior estimation process (see FIG. 12) by the CPU 51, and after the estimated destination is estimated, the position indicated by the “home address” information ( The route from the home position to the estimated destination is searched.

  The result of this route search is the result of the destination / behavior proposal process (see FIG. 13) executed by the CPU 51 together with the result of the route search performed based on the information of the start position stored in the search start data area 53c. If the current position of the vehicle is on the route searched for in the route search or within a predetermined distance from the route, the vehicle is traveling toward the estimated destination. to decide. Therefore, in this case, the estimated destination is proposed to the passenger. On the other hand, when it is determined that the vehicle is not traveling toward the estimated destination, the estimation of the estimated destination is not executed. Therefore, the destination desired by the passenger can be proposed more accurately.

  The “driver registration” information of the user information registration unit 54d1 is imaged by the camera 70 in which the image recognition processor 65 is provided for the driver seat in the boarding analysis process (see FIG. 10) executed by the CPU 51. Referenced when identifying a driver from face image data. In other words, since the driving of the vehicle is most likely to be performed by the user and his / her family, when identifying the driver of the vehicle, the person registered in the “driver registration” information, that is, the user's family The person registered as driving the vehicle is identified with priority.

  Further, the “family” information in the user information registration unit 54d1 is obtained from the camera 70 provided by the image recognition processor 65 at a seat position other than the driver seat in the boarding analysis process (see FIG. 10) executed by the CPU 51. This is referred to when the passenger corresponding to the face image data is specified from the face image data captured by the above. In other words, since the person boarding the vehicle is most likely the user and his / her family, when identifying the passenger, the person registered in the “family” information, that is, the user including the user Identify family first.

  On the other hand, the passenger information registration unit 54d2 registers "name" information, "driving history" information, "ride date" information, and "face image" information for each person registered as a passenger. Among these, the “name” information is information indicating the name of each person registered as a passenger, and in the boarding analysis process (see FIG. 10) executed by the CPU 51, the driver and the passenger are specified. , Used to identify each person to be recognized.

  The “driving history” information indicates, for each person registered as a passenger, whether or not the vehicle equipped with the navigation device 50 has been driven in the past in association with the “name” information of the person. "Driving history" information when the image recognition processor 65 identifies a driver from face image data captured by the camera 70 provided for the driver's seat. The person who is registered as “Yes” in the above, that is, the person who has driven the vehicle in the past is specified with priority.

  The “boarding date” information is information indicating the date on which the person boarded in association with the “name” information of each person registered as a passenger, and the image recognition processor 65 is placed at each seating position. When the passenger is specified from the face image data captured by the camera 70 provided for the person, the person who has a large number of boarding days registered in the “boarding date” information and registered in the “boarding date” information. The person whose previous boarding date is close to the current boarding date is specified with priority.

  The “face image” information is information indicating face image data registered in association with the “name” information of each person registered as a passenger. The image recognition processor 65 performs pattern matching between the face image data captured by the camera 70 and the face image data registered in the “face image” information, thereby driving the face image captured by the camera 70. Identify passengers and passengers. Then, the CPU 51 specifies the name of the specified person from the “name” information, and stores it in the boarding information data area 53b as the driver and passenger information.

  Registration of the user information registration unit 54d1 is performed by a user or a vehicle sales dealer or the like operating the touch panel 59 or the operation key 60. The registration of the “name” information and the “face image” information in the passenger information registration unit 54d2 is performed by the user or the like operating the touch panel 59 or the operation key 60. At this time, the face image data registered in the “face image” information is selected by the user or the like from one or more face image data captured by the camera 70.

  Further, in the process of identifying the driver and passengers by the image recognition processor 65, the face image data captured by the camera 70 is the face image data registered in the “face image” information of the passenger information registration unit 54d2. If it is determined that they do not match, the CPU 51 determines that the person who has boarded the vehicle is not registered in the passenger information DB 54d, displays the face image on the LCD 58, and then displays the person's face for the face image. You may be prompted to enter a name. When a name is input, the name and face image data may be associated with each other and registered in the “name” information and “face image” information of the passenger information registration unit 54d2.

  On the other hand, the “driving history” information of the passenger information registration unit 54d2 is registered as “none” when the “name” information and the “face image” information are newly registered, and the boarding analysis processing ( 10), when a person corresponding to the “name” information is recognized as a driver, the “driving history” information corresponding to the “name” information is rewritten to “present”.

  Further, the “boarding date” information of the passenger information registration unit 54d2 is obtained every time the person corresponding to the “name” information is recognized as a driver or a passenger by the boarding analysis process (see FIG. 10) executed by the CPU 51. In addition, the boarding date is registered in addition to the “boarding date” information corresponding to the “name” information.

  Returning to FIG. 1, the description will be continued. The schedule DB 54e is a database for registering the movement schedule estimated based on the conversation voice data acquired from the mobile phone 10, the schedule book data, and the conversation voice data acquired by the microphone 63 provided in the navigation device 50. It is. Here, the details of the schedule DB 54e will be described with reference to FIG. FIG. 3 is a schematic diagram schematically showing an example of the contents of the schedule DB 54e.

  In this schedule DB 54e, as shown in FIG. 3, the destination 54e2, the scheduled start date 54e3, the scheduled end date 54e4, the estimated arrival time are associated with the database number (DB_No.) 54e1 that is identification information of each movement schedule. Various information relating to the movement schedule such as 54e5, scheduled departure time 54e6, information source 54e7, person 54e8, and registration date 54e9 are registered.

  The destination 54e2 indicates the name of the final destination of the movement schedule corresponding to the database number 54e1, and the name of the place extracted and specified from the conversation voice data or schedule book data is registered. The estimated destination proposed by the CPU 51 is performed based on the name of the destination indicated by the destination 54e2.

  The scheduled start date 54e3 and the scheduled end date 54e4 indicate the scheduled start date and the scheduled end date of the movement schedule corresponding to the database number 54e1, and the estimated arrival time 54e5 and the scheduled departure time 54e6 are stored in the database number 54e1. It shows the scheduled arrival time and scheduled departure time of the corresponding movement schedule. All of these are estimated and registered based on the date and time extracted and specified from conversation voice data and schedule book data.

  If the scheduled start date or the scheduled end date cannot be estimated from the conversation voice data or the schedule book data, “unknown” is registered in the scheduled start date 54e3 and the scheduled end date 54e4 (in the example of FIG. 3). The case where the database number 54e1 is “7” is applicable). Further, when the estimated arrival time and the estimated departure time cannot be estimated from the conversation voice data and the schedule book data, “unknown” is registered at the estimated arrival time 54e5 and the estimated departure time 54e6 (in the example of FIG. 3). And the database number 54e1 is “7” and “8”).

  However, even if the scheduled end date and scheduled arrival time cannot be estimated from the conversation voice data or schedule book data, if the scheduled start date and scheduled departure time can be estimated from the conversation voice data or schedule book data, the CPU 51 The estimated travel time from the home position to the destination is calculated based on the information in the road map DB 54c, and the estimated end time and the estimated arrival time are estimated by adding the estimated travel time to the scheduled start date and the scheduled departure time. Then, the estimated scheduled end date and estimated arrival time are registered in the scheduled end date 54e4 and the estimated arrival time 54e5.

  In addition, even if the scheduled start date and scheduled departure time cannot be estimated from the conversation voice data or schedule book data, if the scheduled end date and estimated arrival time can be estimated from the conversation voice data or schedule book data, the CPU 51 The estimated travel time from the home position to the destination is calculated based on the information in the road map DB 54c, and the estimated start date and the scheduled departure time are estimated by subtracting the estimated travel time from the estimated end date and the estimated arrival time. . Then, the estimated scheduled start date and scheduled departure time are registered in the scheduled start date 54e3 and scheduled departure time 54e6.

  The information source 54e7 indicates the information source in which the movement schedule corresponding to the database number 54e1 is generated. When the movement schedule is generated based on the schedule book data, “schedule” is registered in the information source 54e7. (In the example of FIG. 3, the case where the database number 54e1 is “1”, “2”, “3”, “8” is applicable) and is generated based on the conversation voice data of the conversation by the telephone function of the mobile phone 10 In this case, “telephone” is registered in the information source 54e7 (in the example of FIG. 3, the case where the database number 54e1 is “5” corresponds), and when generated based on other conversational voice data, “Conversation” is registered in 54e7 (in the example of FIG. 3, the case where the database number 54e1 is “4”, “6”, “7” corresponds).

  Whether or not the conversation voice data acquired from the mobile phone 10 is a conversation by the telephone function of the mobile phone 10 is determined based on whether or not the name of the other party is added to the acquired conversation voice data file. Judgment by That is, if the name of the other party is added to the conversation voice data file, it is determined that the conversation voice data is a conversation by the telephone function of the mobile phone 10.

  The person 54e8 indicates the name of a person estimated to act together at the destination indicated by the destination 54e2 in the movement schedule corresponding to the database number 54e1, and is estimated from the conversation voice data and schedule book data. Is registered. Further, the name of the mobile phone owner and the name of the other party in the conversation voice data acquired by the mobile phone 10 are also registered in this person 54e8.

  The registration date 54e9 indicates the registration date of the movement schedule corresponding to the database number 54e1. The registration date registered here is not the date when the movement schedule is registered with respect to the schedule 54e, but the recording date of the conversation voice data for which the corresponding movement schedule is generated or the input date of the schedule book data. is there.

  That is, when the movement schedule is generated based on the conversation voice data acquired from the mobile phone 10, the recording date included in the file of the conversation voice data is registered as the registration date 54e9, and the movement schedule is based on the schedule book data. Is generated, the input date of the schedule book data is registered in the registration date 54e9. In addition, when a movement schedule is produced | generated based on the conversation audio | voice data in the vehicle acquired with the microphone 63 provided in the navigation apparatus 50, the date shown by the time measuring circuit 51a at the time of the movement schedule being produced | generated is shown. Registered on registration date 54e9.

  The CPU 51 refers to the schedule DB 54e by executing the destination / behavior estimation process (see FIG. 12), and gets the boarding information (passenger number, boarding date / time, driver and passengers) stored in the boarding information data area 53b. ) Based on the contents of each travel schedule registered in the schedule DB 54e (destination 54e2, scheduled start date 54e3, scheduled end date 54e4, scheduled arrival time 54e5, scheduled departure time 54e6, information source 54e7, person 54e8 and registration date) 54e9), an accurate estimated destination is estimated.

  Returning to FIG. 1, the description will be continued. The passenger / behavior history DB 54f is a database for accumulating history information of destinations (destinations) headed to the past by the vehicle on which the navigation device 50 is mounted. Here, the details of the boarding vehicle / behavior history DB 54f will be described with reference to FIG. FIG. 4 is a schematic diagram schematically showing an example of the contents of the passenger / action history DB 54f.

  In the passenger / action history DB 54f, as shown in FIG. 4, a destination number 54f2, a date 54f2, a departure time 54f4, an arrival time 54f5 are associated with a database number (DB_No.) 54f1 which is identification information for each history information. The history information such as the driver 54f6 and the passenger 54f7 is registered.

  The destination 54f2 indicates the final destination (destination) actually headed by the vehicle. Further, the date 54f3 indicates the departure date to the destination, and the departure time 54f4 indicates the departure time to the destination. The arrival time 54f5 indicates the arrival time of the destination. Further, the driver 54f6 indicates a person who drives the vehicle toward the destination, and the passenger 54f7 indicates a person who rides the vehicle toward the destination.

  The passenger / behavior history DB 54f updates the passenger / behavior history DB 54f when it is determined in the guidance process (see FIG. 14) executed by the CPU 51 that the vehicle has arrived at the destination. Specifically, the arrival date is registered in the destination 54f2 in association with the smallest database number 54f1 in which history information is not registered, and the boarding date is based on the boarding date and time stored in the boarding information data area 53b. Is registered in the date 54f3 as the departure date, the boarding time is registered in the departure time 54f4 as the departure time, and the time indicated by the timing circuit 51a is registered in the 54f5 as the arrival time when it is determined that the arrival time is reached. Information on the driver and passengers stored in the boarding information data area 53b is registered in the driver 54f6 and passenger 54f7, respectively.

  In addition, when it is determined that the vehicle has arrived at the destination, there are movement schedules registered in the schedule DB 54e in which the scheduled start date indicated by the scheduled start date 54e3 is a past date. To do so, the destination indicated by the destination 54e2 of the travel schedule is registered in the destination 54f2 of the passenger / action history DB 54f, and the scheduled start date indicated by the scheduled start date 54e3 of the travel schedule is After registering on the date 54f3 of the action history DB 54f, register “stop” indicating that the movement toward the destination is stopped at the departure time 54f4 (in the example of FIG. 4, the database number 54f1 is “ 1 ”).

  When the CPU 51 estimates the estimated destination by the destination / behavior estimation process (see FIG. 12), the passenger / behavior history DB 54f has no schedule on the boarding day in the schedule DB. If it is determined that there are no plans to cross the day within the number of days and time range, it is referred to. It is also referred to when the estimated destination needs to be estimated again. Then, for each destination set in the past registered in the passenger / behavior history DB 54f, the number of times, the time, the time, the tendency of the driver and the passenger are analyzed, and from the analysis result, the boarding information data A destination having a tendency similar to the boarding information (boarding date and time, driver, passenger information) stored in the area 53b and having a set number of times is preferentially estimated as the estimated destination.

  Returning to FIG. 1, the description will be continued. The current position detection device 55 is for detecting the current position (absolute coordinate value composed of latitude and longitude) of the vehicle on which the navigation device 50 is mounted, and GPS that measures the position of the vehicle using an artificial satellite. (Global Positioning System) One or more of a receiving device 55a, a geomagnetic sensor 55b, a gyro sensor 55c, and a vehicle speed sensor 55d that detect the azimuth of the vehicle by detecting geomagnetism are used.

  The BT communication control circuit 56 includes a Bluetooth antenna 57 and has a function similar to that of the BT communication control circuit 15 of the mobile phone 10. The navigation device 50 is connected to the mobile phone via the BT communication control circuit 56. Wireless communication is performed with the mobile phone 10, and conversation voice data and schedule book data are acquired from the mobile phone 10.

  The LCD 58 displays menus, operation states, and the like according to the operation of the touch panel 59 and the operation keys 60, and displays a map around the vehicle or a route searched for a route, a search route, a surrounding facility guidance screen, and the like. It is a display device. The estimated destination estimated by the navigation device 50 is also displayed on the LCD 58.

  The touch panel 59 is an input device provided on the display panel surface of the LCD 58, and outputs position information indicated by an indicator (such as a user's finger or a touch pen) in the same manner as the touch panel 22 provided on the mobile phone 10. As a result, the CPU 51 determines whether or not a button or icon displayed on the LCD 58 has been pressed, or recognizes an input character. The operation key 60 is an input device that accepts switching of various functions of the navigation device 50 by the user and instructions for various operations together with the touch panel 59.

  The speaker 61 is an output device that converts a sound signal into sound and outputs the sound to the outside (sound emission). For example, a guidance sound when performing route guidance by sound is output. The speaker 61 may also be used as an audio speaker.

  The pressure sensor 62 is embedded and arranged for each seat position of the seat, and detects whether or not a pressure of a predetermined level or more is applied at the corresponding seat position. If it is detected by the pressure sensor 62 that a pressure of a predetermined level or higher is applied, the CPU 51 determines that the occupant is seated at the seat position where the pressure sensor 62 is embedded. Then, the number of passengers in the vehicle is detected from the number of pressure sensors 62 that are detected to have been applied with a pressure of a predetermined level or higher.

  The microphone 63 is an input device that converts a passenger's voice emitted in the vehicle into voice data, and the voice data converted by the microphone 19 is output to the voice recognition processor 64.

  The voice recognition processor 64 is a processor for recognizing and extracting a predetermined keyword included in the voice data. The voice recognition processor 64 analyzes the voice data input from the microphone 63, decompresses and analyzes the compressed and encoded conversation voice data acquired from the mobile phone 10, and converts the voice data into the voice data. A process for extracting a keyword that can specify the place, date, and person included is performed. The CPU 51 estimates a movement schedule based on each keyword extracted by the voice recognition processor 64.

  The image recognition processor 65 is a processor that performs image recognition by a pattern matching method. The image recognition processor 65 is connected to a camera 70 arranged corresponding to each seat position of each seat. Then, the image recognition processor 65 selects the face image data closest to the face image data captured by each camera 70 from the face image data registered in the “face image” information of the passenger information DB 54d (see FIG. 2). Extract from

  The image recognition processor 65 registers the face image data captured by the camera 70 provided for the driver's seat in the “face image” information in the closest passenger information DB 54d (see FIG. 2). When the face image data is extracted, the CPU 51 specifies the name of the person corresponding to the face image data from the “name” information in the passenger information DB 54, and uses the person with that name as the driver in the boarding information data area 53b. Store.

  Further, the “face image” in the passenger information DB 54d (see FIG. 2) closest to the face image data captured by the image recognition processor 65 by the camera 70 provided for the seat position other than the driver's seat. When the face image data registered in the information is extracted, the CPU 51 specifies the name of the person corresponding to the face image data from the “name” information in the passenger information DB 54, and the person with that name is boarded as a passenger. Stored in the information data area 53b.

  Next, each process executed by the CPU 11 of the mobile phone 10 will be described with reference to FIGS. First, FIG. 5 is a flowchart showing main processing executed by the CPU 11 of the mobile phone 10. This main process executes main processes of the mobile phone 10 and is executed when the power of the mobile phone 10 is started and until the power is turned off.

  In this main process, first, an initialization process is executed (S11), initial values are set in a predetermined area of the RAM 13, and various settings are performed so that each unit of the mobile phone 10 is in an operating state. In the subsequent process of S12, based on the output signal from the operation key 23, it is determined whether or not there is an instruction to record a conversational voice from the user (S12). If it is determined that there is an instruction to record conversational speech (S12: Yes), conversation acquisition processing is executed (S13), and conversational speech is recorded. Details of the conversation voice processing will be described later with reference to FIG.

  After the process of S13, the process proceeds to S14. If it is determined as a result of the process of S12 that there is no conversation voice recording instruction (S12: No), the process of S13 is skipped and the process proceeds to S14. In the process of S14, based on the output signal from the touch panel 22, it is determined whether or not the input of the schedule has been started by the user. If it is determined that the schedule input has started (S14: Yes), the input schedule book data is added to the schedule book data area 14b together with the input date and time (S15). In the process of S15, the date and time at the time when it is determined that the input of the schedule is started by the process of S14 is acquired from the clock circuit 11a and added to the schedule book data area 14b as the input date and time.

  After the process of S15, the process proceeds to S16. As a result of the process of S14, when it is not determined that the schedule input has started (S14: No), the process of S15 is skipped and the process proceeds to S16. In the process of S16, the BT communication control circuit 15 determines whether or not there is a connection request by Bluetooth from an external device (whether or not a connection request is received), and when it is determined that there is a connection request by Bluetooth. (S16: Yes), Bluetooth connection processing is executed (S17).

  The details of the Bluetooth connection process will be described later with reference to FIG. 7. If the connection request source is the navigation device 50, the conversation voice data stored in the conversation voice data area 14a according to the control signal from the navigation device 50. The schedule book data stored in the schedule book data area 14 b is transferred to the navigation device 50.

  After the process of S17, the process proceeds to S18. If it is determined that there is no Bluetooth connection request as a result of the process of S16 (S16: No), the process of S17 is skipped and the process proceeds to S18. In the process of S18, other processes for realizing various functions of the mobile phone 10 are executed according to various control signals received by the mobile communication control circuit 17, the operation status of the touch panel 22 and the operation keys 23, and the like. . For example, the telephone call by the telephone function is realized by the process of S18.

  And after the process of S18 is completed, it returns to the process of S12. Then, the processes from S12 to S18 are repeatedly executed until the power is turned off. Thus, various processes are executed according to various control signals received by the mobile communication control circuit 17 and the operation status of the touch panel 22 and the operation keys 23 while the mobile phone 10 is powered on. .

  Next, a conversation acquisition process executed by the CPU 11 of the mobile phone 10 will be described with reference to FIG. FIG. 6 is a flowchart showing the conversation acquisition process. As described above, this conversation acquisition process is executed when it is determined that there is a conversation voice recording instruction from the user in the main process shown in FIG. 5 (see S13 in FIG. 5). Is a process of recording.

  In this conversation acquisition process, it is first determined whether or not a call is being made by the telephone function in the mobile phone 10 (S21). If the call is in progress (S21: Yes), the telephone number of the other party is acquired (S22). ). Then, the name of the other party corresponding to the telephone number is specified from the address book DB 14c, and the name is stored in the RAM 13 (S23). Here, the stored name of the other party is used in the process of S29 described later.

  Thereafter, the voice data acquired from the microphone 19 and the voice data received by the portable communication control circuit 17 are synthesized to generate conversation voice data, and temporarily stored in the RAM 13 (S24). Then, the synthesized conversation voice data stored in the RAM 13 is compression-encoded by the MP3 system, the AAC system, or the like, and the compressed and encoded conversation voice data is stored in the conversation voice data area 14a (S25).

  Next, based on the output signal from the operation key 23, it is determined whether or not the user has instructed the recording end of the conversation voice (S26). If there is no recording end instruction (S26: No), the process returns to the process of S21. The processes from S21 to S26 are executed again. Then, in the process of S26, the processes of S21 to S26 are repeatedly executed until it is determined that there is a recording end instruction. Note that the processing of S22 and S23 is omitted after the first execution.

  After that, if it is determined by the process of S26 that there is a recording end instruction (S26: No), the process repeats the process from S21 to S26 and shifts to the process of S28. As a result, the conversation voice of the telephone call function is recorded, and the compression-coded conversation voice data is stored in the conversation voice data area 14a. In the process of S26, even when it is determined that there is an instruction to end the call by the telephone function, it is determined that there is an instruction to end the recording at the same time, the process from S21 to S26 is repeated, and the process proceeds to S28.

  On the other hand, if the result of the processing in S21 is not during a call, the conversation voice data of the conversation voice around the mobile phone 10 acquired by the microphone 19 is temporarily stored in the RAM 13 (S27). Next, the process proceeds to S25, where the conversation voice data stored in the RAM 13 is compression-encoded, and the compression-encoded conversation voice data is stored in the conversation voice data area 14a.

  Then, while it is determined by the process of S26 that is executed after the process of S25 that there is no instruction to end recording of the conversational voice (S26: No), the processes of S21, S27, S25, and S26 are repeatedly executed. . Thereafter, if it is determined by the process of S26 that there is a recording end instruction (S26: No), the process repeats S21, S27, S25, and S26 and goes to the process of S28. Thereby, the conversation voice around the mobile phone 10 is recorded, and the compression-coded conversation voice data is stored in the conversation voice data area 14a.

  In the process of S28, the current date and time is acquired from the time measuring circuit 11a as the recording date and time of the conversation voice data. When the conversation voice data stored in the conversation voice data area 14a is recorded with the name of the owner of the mobile phone 10 registered in the address book DB 14c and the conversation voice of the telephone with the telephone function, the process of S23 is performed. The name of the other party stored in the RAM 13 and the recording date and time acquired by the processing in S28 are added to form a file, which is stored in the conversation voice data area 14a (S29). And this conversation acquisition process is complete | finished.

  As described above, by executing the conversation acquisition process, the conversation voice of the call by the telephone function or the conversation voice around the mobile phone 10 is recorded, and the compressed and encoded conversation voice data is filed and the conversation voice data is recorded. Stored in area 14a.

  Next, the Bluetooth connection process executed by the CPU 11 of the mobile phone 10 will be described with reference to FIG. As described above, this Bluetooth connection process is executed when the BT communication control circuit 15 determines that there is a Bluetooth connection request from an external device in the main process shown in FIG. 5 (FIG. 5). This is a process for transmitting and receiving data in accordance with a control signal from the counterpart device.

  In this Bluetooth connection process, first, it is determined whether the connection request by Bluetooth is a connection request from the navigation device 50 (S31), and if it is determined that the connection request is from the navigation device 50 (S31: Yes). ), A connection permission signal is transmitted to the navigation device 50 (S32). As a result, it is determined in the navigation device 50 that a connection has been established with the mobile phone 10, and a new control signal is transmitted from the navigation device 50 to the mobile phone 10.

  In the subsequent processes from S33 to S43, the content of the control signal received from the navigation device 50 is determined in the BT communication control circuit 15, and the process corresponding to the control signal is executed. First, in the process of S33, it is determined whether or not a control signal is received from the navigation device 50. If not received (S33: No), the process of S33 is repeatedly executed until the control signal is received. As a result, the process waits until a control signal is received from the navigation device 50.

  If it is determined in the process of S33 that a control signal has been received from the navigation device 50 (S33: Yes), it is determined whether the received control signal is a transfer request for conversation voice data file information (S34). As a result, if it is a transfer request for conversation voice data file information (S34; Yes), the file names of all the conversation voice data stored in the conversation voice data area 14a and the recording date and time are transmitted (S35). .

  Thereby, the navigation apparatus 50 specifies the file name of the conversation voice data recorded after the previously acquired conversation voice data based on the file name of the conversation voice data transmitted from the mobile phone 10 and the recording date and time. Then, the transfer request for the specified conversation voice data file is transmitted to the mobile phone 10 (see S75 in FIG. 9).

  On the other hand, if the received control signal is not a conversation voice data file information transfer request as a result of the process of S34 (S34: No), it is then determined whether or not it is a conversation voice data file transfer request (S34: No). S36). As a result, when it is a transfer request of the conversation voice data file (S36: Yes), the conversation voice data having the file name designated by the transfer request is read from the conversation voice data area 14b and transmitted (S37). Thereby, the conversation voice data recorded by the mobile phone 10 is transmitted to the navigation device 50.

  On the other hand, if the received control signal is not a conversation voice data file transfer request as a result of the process of S36 (S36: No), it is then determined whether or not it is a transfer request for the input date and time of schedule book data. (S38). As a result, if it is a transfer request for the input date / time of the schedule book data (S38: Yes), the latest input date / time of the schedule book data stored in the schedule book data area 14b is transmitted (S39). Thereby, the navigation device 50 transfers the schedule book data if there is schedule book data input after the input of the previously acquired schedule book data based on the latest input date and time of the schedule book data transmitted from the mobile phone 10. The request is transmitted to the mobile phone 10 (see S80 in FIG. 9).

  On the other hand, if the received control signal is not a schedule book data input date / time transfer request as a result of the process of S38 (S38: No), then it is determined whether it is a schedule book data transfer request (S40). . As a result, if it is a transfer request for the schedule book data (S40: Yes), the schedule book data stored in the schedule book data area 14b is transmitted (S41). As a result, the schedule book data input to the mobile phone 10 is transmitted to the navigation device 50.

  On the other hand, if the received control signal is not a schedule book data transfer request as a result of the process of S40 (S40: No), it is then determined whether or not it is a connection end signal (S42). If it is not a connection end signal (S42: No), processing according to the received control signal is executed (S43). When the process of S35, S37, S39, S41 or S43 is completed, the process returns to the process of S33. Then, the process waits until the control signal is received again from the navigation device 50. When the control signal is received, the process according to the control signal is executed.

  On the other hand, if the received control signal is a connection end signal as a result of the process of S42 (S42: Yes), this Bluetooth connection process is ended. Thereby, the wireless communication by Bluetooth of the data performed with the navigation apparatus 50 is complete | finished, and the transfer process of the conversation voice data and schedule book data from the mobile telephone 10 to the navigation apparatus 50 is completed.

  On the other hand, as a result of the processing of S31, when it is determined that the connection request by Bluetooth is a connection request from other than the navigation device 50 (S31: No), the control signal and various data are received from the partner device that has made the connection request. In addition, by transmitting a control signal and various data to the partner device, data is transmitted to and received from the partner device (S45), and the Bluetooth connection process is terminated.

  Next, various processing executed by the CPU 51 of the navigation device 50 will be described with reference to FIGS. First, FIG. 8 is a flowchart showing main processing executed by the CPU 51 of the navigation device 50. This main process executes main processes of the navigation device 50, and is executed when the power of the navigation device 50 is started and until the power is turned off.

  In this main process, first, an initialization process is executed (S51), initial values are set in a predetermined area of the RAM 53, and various settings are performed so that each part of the navigation device 50 is in an operating state. The estimated state flag 53a, the data acquisition process flag, the data update flag, the estimated state flag, and the proposal process flag provided in the RAM 53 are initialized in the process of S51, and the estimated state flag 53a is set to “N”. The processing flag is set to OFF, the data update flag is set to OFF, the estimation state flag is set to “not estimated”, and the proposal processing flag is set to OFF.

  Further, as one process of the initialization process, the position information of the vehicle at the time of turning on the power is acquired from the current position detecting device 55 and stored in the search starting point data area 53c (S52). The position information stored in the search origin data area 53c is referred to in the destination / behavior estimation process (see FIG. 12) in S58.

  After the initialization processing by S51 and S52 is completed, in the subsequent processing of S53, it is determined whether or not the data acquisition processing flag stored in the RAM 53 is on, and if the data acquisition processing flag is off (S53: No) Since it can be determined that conversation voice data and schedule book data have not been acquired from the mobile phone 10, data acquisition processing is executed (S54), and conversation voice data and schedule book data are acquired from the mobile phone 10 I do. Details of this data acquisition processing will be described later with reference to FIG.

  After the process of S54, the process proceeds to S55. If it is determined as a result of the processing of S53 that the data acquisition processing flag is on (S53: Yes), it can be determined that conversation voice data and schedule book data have been acquired from the mobile phone 10, so S54 This process is skipped, and the process proceeds to S55. In the processing of S55, boarding analysis processing is executed, and when boarding the vehicle, the number of passengers, boarding date and time, driver and passengers are specified. Details of this boarding analysis processing will be described later with reference to FIG.

  Next, a schedule DB update process is executed (S56), and movement is performed based on the conversation voice data and schedule book data acquired from the mobile phone 10 by the data acquisition process of S54 and the conversation voice data in the vehicle acquired by the microphone 63. The schedule is estimated, and this is registered and updated in the schedule DB 54e. Details of the schedule DB update process will be described later with reference to FIG.

  Next, it is determined whether or not the estimated state flag stored in the RAM 53 is “estimated” (S57), and the estimated state flag is not “estimated”. If it is “re-estimation” (S57: No), the estimated destination is not estimated or the estimated destination is required to be estimated again, so the destination / behavior estimation process is executed. (S58), the estimated destination is estimated from the travel schedule registered in the schedule DB 54e based on the number of passengers, the boarding date and time, the driver, and the passengers identified by the boarding analysis process of S55. Details of the destination / behavior estimation process will be described later with reference to FIG.

  After the process of S58, the process proceeds to S59. If it is determined that the estimated state flag is “estimated” as a result of the process of S57 (S57: Yes), the estimated destination is estimated, so the process of S58 is skipped. Thus, the process proceeds to S59. In the process of S59, it is determined whether or not the proposal process flag stored in the RAM 53 is on. If the proposal process flag is off as a result (S59: No), the estimated destination is proposed to the passenger. Since this means that it has not been performed, the destination / behavior proposal process is executed (S60), and the estimated destination estimated by the destination / behavior estimation process of S58 is proposed to the passenger. Details of the destination / action proposal processing will be described later with reference to FIG.

  And after the process of S60, it transfers to the process of S61. If the proposal process flag is on as a result of the process of S59 (S59: Yes), it means that the estimated destination has been proposed to the passenger, so the process of S60 is skipped. The process proceeds to S61. In the process of S61, a guidance process is executed. The details of the guidance process will be described later with reference to FIG. 14. In this guidance process, route guidance to a registered destination is performed. Further, when the estimated destination is proposed to the passenger by the destination / behavior proposal processing in S60, if the estimated destination is accepted by the passenger, route guidance is performed using the estimated destination as the destination. .

  Thereafter, other processes for realizing various functions of the navigation device 50 are executed according to the operation status of the touch panel 59 and the operation keys 60, the current position of the vehicle detected by the current position detection device 55, and the like (S62). . Then, after the process of S62, the process returns to the process of S53, and the processes of S53 to S62 are repeatedly executed until the power is turned off.

  Next, a data acquisition process executed by the CPU 51 of the navigation device 50 will be described with reference to FIG. FIG. 9 is a flowchart showing data acquisition processing. As described above, the data acquisition process is executed when the data acquisition process flag is off in the main process shown in FIG. 8 (see S54 in FIG. 8). This is a process for acquiring schedule book data.

  In this data acquisition process, first, the BT communication control circuit 56 is instructed to transmit a connection request to the mobile phone 10 (S71). When receiving the connection request, the mobile phone 10 transmits a connection permission signal to the navigation device 50 (see S32 in FIG. 7).

  Therefore, in the data acquisition process, after the process of S71, it is determined whether or not a connection permission signal is received from the mobile phone 10 in the BT communication control circuit 56 within a predetermined time after the connection request is transmitted (S72). As a result, when the connection permission signal has not been received (S72: No), the power of the mobile phone 10 is turned off, or the mobile phone 10 does not exist within the range where wireless communication by Bluetooth is possible. Because of the reason, wireless communication by Bluetooth cannot be performed with the mobile phone 10, the subsequent processing is skipped and the data acquisition processing is terminated.

  On the other hand, if it is determined that a connection permission signal has been received from the mobile phone 10 as a result of the processing of S72 (S72: Yes), it is determined that a connection has been established with the mobile phone 10, and then BT communication control is performed. The circuit 56 is instructed to transmit a conversation voice data file information transfer request to the mobile phone 10 (S73).

  As a result, the file name of the conversation voice data and the information related to the recording date and time are transmitted from the mobile phone 10 (see S35 in FIG. 7). Next, each received from the mobile phone 10 by the BT communication control circuit 56 The recording date and time of the conversation voice data is compared with the recording date and time of the conversation voice data stored in the conversation voice data area 54a, and the previously acquired conversation voice data stored in the conversation voice data area 54a is stored in the mobile phone 10. After the recording, it is determined whether there is conversation voice data recorded by the mobile phone 10 (S74).

  As a result, when it is determined that there is conversation voice data recorded after the recording of the previously acquired conversation voice data (S74: Yes), the file name of all corresponding conversation voice data is designated and acquired last time. The BT communication control circuit 56 is instructed to transmit to the mobile phone 10 a transfer request for all the conversational voice data recorded after the recording of the conversational voice data (S75). Thereby, the conversation voice data of the designated file name is transmitted from the mobile phone 10 (see S37 in FIG. 7).

  Therefore, the conversation voice data received from the mobile phone 10 by the BT communication control circuit 56 is stored in the conversation voice data area 54a (S76). Thereby, various conversation voice data recorded by the mobile phone 10 are acquired. Further, since the navigation device 50 requests the mobile phone 10 to transfer only the conversation voice data recorded after the recording of the conversation voice data acquired last time, only the minimum necessary conversation voice data is transferred to the mobile phone 10. It is transmitted from the telephone 10 to the navigation device 50. As a result, the transfer time of the conversation voice data can be shortened, and consumption of the secondary battery in the mobile phone 10 can be suppressed.

  Next, the data update flag provided in the RAM 53 is set to ON (S77), and the process proceeds to S78. By turning on the data update flag, in the schedule DB update process (see FIG. 11) which is the process of S56 of the main process, the schedule DB 54e is based on the conversation voice data stored in the conversation voice data area 54a by the process of S76. Is updated. On the other hand, as a result of the process of S74, when it is determined that there is no conversation voice data recorded after the recording of the previously acquired conversation voice data (S74: No), the process of S75 to S77 is skipped and the process of S78 is performed. Migrate to

  In the process of S78, the BT communication control circuit 56 is instructed to transmit a transfer request for the input date and time of the schedule book data to the mobile phone 10. Thereby, the latest input date and time of the schedule book data is transmitted from the mobile phone 10 (see S39 in FIG. 7). Therefore, the latest input date / time of the schedule book data received from the mobile phone 10 by the BT communication control circuit 56 is compared with the input date / time of the schedule book data stored in the schedule book data area 54b, and the result is stored in the schedule book data area 54b. After the previously acquired schedule book data stored is input by the mobile phone 10, it is determined whether there is newly input schedule book data (S79).

  As a result, if there is schedule book data input after inputting the previously acquired schedule book data (S79: Yes), the BT communication control circuit 56 is sent to the mobile phone 10 so as to transmit a schedule book data transfer request. (S80). Thereby, the schedule book data is transmitted from the mobile phone 10 (see S41 in FIG. 7). Therefore, from the schedule book data received from the mobile phone 10 by the BT communication control circuit 56, the schedule book data input after the input of the previously acquired schedule book data is extracted, and the extracted schedule book data is stored in the schedule book data area. 54a is stored (S81). Thereby, the schedule book data input into the mobile phone 10 is acquired.

  Then, the data update flag provided in the RAM 53 is set to ON (S82), and the process proceeds to S83. Even if the data update flag is not turned on because there is no conversation voice data to be obtained in the mobile phone 10 by the processing of S82, the data update flag is turned on when the schedule book data is obtained. When the data update flag is turned on, in the schedule DB update process (see FIG. 11) which is the process of S56 of the main process, based on the schedule book data stored in the schedule book data area 54b by the process of S81, The schedule DB 54e is updated.

  On the other hand, as a result of the process of S79, if it is determined that there is no schedule book data input after the input of the previously acquired schedule book data (S79: No), the processes of S80 to S82 are skipped and the process of S83 is performed. Migrate to

  In the process of S83, the BT communication control device 56 is instructed to transmit a connection end signal to the mobile phone 10. Thus, when the mobile phone 10 receives this connection end signal, the wireless communication by Bluetooth between the mobile phone 10 and the navigation device 50 is ended.

  Next, the data acquisition process flag provided in the RAM 53 is set to ON (S84), and the data acquisition process is terminated. By turning on the data acquisition processing flag, it is possible to indicate that conversation voice data or schedule book data has been acquired from the mobile phone 10, and thereafter, this data acquisition processing is not executed by the main processing (see FIG. 8). It can be. Therefore, once the navigation device 50 acquires the conversation voice data and the schedule book data from the mobile phone 10 after the power is turned on, the navigation apparatus 50 duplicates the conversation voice data and the schedule book data from the mobile phone 10 thereafter. It is possible to prevent receiving a transfer.

  Next, the boarding analysis process executed by the CPU 51 of the navigation device 50 will be described with reference to FIG. FIG. 10 is a flowchart showing this boarding analysis processing. As described above, the boarding analysis process is executed in the main process shown in FIG. 8 (see S55 in FIG. 8). When boarding the vehicle, the number of passengers, the boarding date and time, the driving This is a process for identifying a passenger and a passenger.

  In this boarding analysis process, first, the current time is acquired from the time measuring circuit 51a (S91). Next, among the pressure sensors 62 provided at the respective seat positions, the number of pressure sensors 62 that are detected to be applied with a predetermined pressure is counted to detect the number of passengers in the vehicle (S92). . Then, it is determined whether or not the vehicle has been boarded by determining whether or not the number of passengers detected by the process of S92 is greater than the number of passengers detected so far (S93). .

  As a result, when it is determined that the number of passengers detected by the process of S92 has not increased more than the number of passengers detected so far and the vehicle has not been boarded (S93: No), the subsequent process Is skipped and the boarding analysis process is terminated.

  On the other hand, if the number of passengers detected by the process of S92 is greater than the number of passengers detected so far and it is determined that the vehicle has boarded (S93: Yes), the number of passengers detected by the process of S92 is detected. The number of passengers is stored in the boarding information data area 53b (S94), and the time acquired by the process of S91 is stored in the boarding information data area 53b as the boarding date and time (S95). Thus, the boarding date and the number of passengers when the vehicle is boarded are specified.

  Next, the image recognition processor 65 is controlled so as to capture a passenger's face image by each camera 70 provided corresponding to each seat position of the seat (S96). As a result, each camera 70 captures a face image of a passenger sitting at the corresponding seat position, and each captured face image data is input to the image recognition processor 65.

  Then, the image recognition processor 65 is instructed to execute processing for specifying the driver (S97). As a result, the image recognition processor 65 compares the face image data captured by the camera 70 provided corresponding to the driver's seat with each face image data registered in the “face image” information of the passenger information DB 54d. Then, the driver is specified by the pattern matching method.

  At this time, the image recognition processor 65 is registered as the person registered in the “driver registration” information in the user information registration unit 54d1 of the passenger information DB 54d, that is, the driver of the vehicle user and his family. Identify the person who gave priority. If the face image data captured by the camera 70 does not match the face image data of the person registered in the “driver registration” information, the face image data other than that person and in the passenger information registration unit 54d2 of the passenger information DB 54d. A person whose “driving history” information is registered as “present”, that is, a person who has driven the vehicle in the past is specified with priority. Furthermore, a person who has a large number of boarding days registered in the “boarding date” information of the passenger information registration unit 54d2, and a person whose previous boarding date registered in the “boarding day” information is close to the current boarding day Specify with priority.

  In addition, the image recognition processor 65 is instructed to execute a process for identifying a passenger (S98). Thus, the image recognition processor 65 causes each face registered in the face image data captured by the camera 70 provided corresponding to each seat position other than the driver's seat and the “face image” information in the passenger information DB 54d. The image data is compared and the passenger is identified by the pattern matching method.

  At this time, the image recognition processor 65 gives priority to the person registered in the “family” information in the user information registration unit 54d1 of the passenger information DB 54d, that is, the person registered as the vehicle user and the family. Identify. In addition, a person who has a large number of boarding days registered in the “boarding date” information of the passenger information registration unit 54d2, and a person whose previous boarding date registered in the “boarding day” information is close to the current boarding day Specify with priority.

  Next, the names of the driver and passengers identified by the image recognition processor 65 are identified from the “name” information in the passenger information DB 54d and stored in the boarding information data area 53b (S99). Thus, the driver and the passenger when the vehicle is boarded are specified.

  Then, the passenger basic DB 54d2 is updated (S100). In this update process, the boarding date stored in the boarding information data area 53 by the process of S95 is added to the “boarding date” information corresponding to the “name” information of the person specified as the driver or the passenger. sign up. In addition, registration is performed in such a manner that information “present” is overwritten on “driving history” information corresponding to the “name” information of the person specified as the driver. When the driver or passenger is specified in the boarding analysis process after the next time, the passenger basic DB 54d2 updated here is used. After the process of S100, this boarding analysis process is terminated.

  Next, the schedule DB update process executed by the CPU 51 of the navigation device 50 will be described with reference to FIG. FIG. 11 is a flowchart showing the schedule DB update process. As described above, this schedule DB update process is executed in the main process shown in FIG. 8 (see S56 in FIG. 8), and the conversation voice acquired from the mobile phone 10 by the data acquisition process shown in FIG. This is a process of updating the schedule DB 54e based on data, schedule book data, and conversation voice data in the vehicle acquired by the microphone 63.

  In this schedule DB update process, first, it is determined whether or not the data update flag stored in the RAM 53 is on (S111). If the data update flag is on (S111: Yes), it means that data is stored and updated in at least one of the conversation voice data area 54a and the schedule book data area 54b in the data acquisition process of FIG. . Therefore, after the data update flag is turned off (S112), if there is schedule book data newly stored in the schedule book data area 54b by the data acquisition process of FIG. A phrase is specified, and a vehicle travel schedule (destination, scheduled start date, scheduled end date, scheduled arrival time, scheduled departure time, person) is estimated from the specified phrase (S113).

  At this time, the input date / time of the schedule book data used as the basis for estimating the movement schedule is also extracted, and the input date / time is associated with the estimated registration date of the movement schedule. In addition, “schedule” is associated as an information source of the movement schedule.

  Thus, by acquiring the schedule book data input to the mobile phone 10, estimating the movement schedule based on the schedule book data, and registering it in the schedule DB 54e, only the movement schedule generated based on the conversation voice is obtained. Not only the schedule book data but also the estimated destination can be estimated. Here, the movement schedule generated based on the conversation voice is often unclear because the source of the information is the conversation voice. However, the schedule book data has a clear place and date. In many cases. Therefore, if the movement schedule is estimated based on the conversation voice data and the schedule book data and then the estimated destination is estimated, the estimated destination can be estimated and proposed more accurately.

  Next, if there is conversation voice data newly stored in the conversation voice data area 54a by the data acquisition process of FIG. 9, a process of extracting a keyword that can specify a place, date, and person from the conversation voice data is executed. The voice recognition processor 64 is instructed (S114). As a result, the speech recognition processor 64 reads the conversational speech data to be processed from the conversational speech data area 54a, and extracts keywords that can specify the location, date, and person.

  Further, from the conversation voice data newly stored in the conversation voice data area 54a, the name of the mobile phone owner, the name of the other party and the recording date and time included in the conversation voice data file are extracted (S115). Here, when the name of the other party is extracted, it is recognized that the conversation voice data is a recording of the contents of the call by the telephone function of the mobile phone 10, and the name of the other party cannot be extracted. The conversation voice data is recognized as a recording of a conversation around the mobile phone 10.

  After the process of S115, the process proceeds to S116. If the data update flag stored in the RAM 53 is OFF as a result of the processing of S111 (S111: No), it means that the conversation voice data area 54a and the schedule book data area 54b have not been updated. To S115, and the process proceeds to S116.

  In the process of S116, the voice recognition processor 64 is instructed to execute a process of extracting a keyword that can specify the place, date, and person from the conversation voice data in the vehicle acquired by the microphone 63. As a result, the voice recognition processor 64 extracts keywords that can specify the location, date, and person from the conversation voice data in the vehicle acquired by the microphone 64.

  Next, the movement schedule (destination, scheduled start date, scheduled end date, scheduled arrival time, scheduled departure time, person) is estimated from the various keywords extracted by the speech recognition processor 64 in the processes of S114 and S116 (S117). ). At this time, when the conversation voice data from which the movement schedule is estimated is acquired from the mobile phone 10, the name of the mobile phone owner or the name of the other party of the call extracted by the process of S115 is Add to “person” in the movement schedule.

  Further, if the conversation voice data from which the movement schedule is estimated is obtained from the mobile phone 10, the recording date and time extracted by the processing of S115 is associated with the registration date of the movement schedule. If it is acquired by the microphone 63, the current time is acquired from the time measuring circuit 51a, and is associated with the registration date of the movement schedule. Furthermore, when it is recognized that the conversation voice data from which the movement schedule is estimated is a recording of the conversation contents by the telephone function of the mobile phone 10, “phone” is used as the information source of the movement schedule. ”And“ conversation ”as the information source in other cases.

  Next, in the travel schedule estimated by the processing of S113 and S117, it is determined whether or not there is a travel schedule with an unknown start date and scheduled departure time (S118). If there is such a travel schedule ( S118: Yes), it is determined whether or not the scheduled end date and the estimated arrival time can be specified in the corresponding movement schedule (S119). As a result, for the travel schedule in which the scheduled end date and the estimated arrival time can be identified (S119: Yes), the estimated travel time from the home position to the destination is calculated based on the information in the road map DB 54c, and the estimated travel time Is estimated from the scheduled end date and estimated arrival time to estimate the scheduled start date and scheduled departure time (S120), and the process proceeds to S121.

  On the other hand, as a result of the process of S119, for the movement schedule for which the scheduled end date and the estimated arrival time cannot be specified, the process of S120 is skipped and the process proceeds to S121. If it is determined as a result of the process in S118 that there is no travel schedule whose scheduled start date and scheduled departure time are unknown, the process proceeds to S121.

  In the process of S121, it is determined whether or not there is a movement schedule whose scheduled end date and estimated arrival time are unknown in the movement schedule estimated by the processes of S113 and S117. : Yes), it is determined whether or not the scheduled start date and the scheduled departure time can be specified in the corresponding travel schedule (S122). As a result, for the travel schedule in which the scheduled start date and scheduled departure time can be specified (S122: Yes), the estimated travel time from the home position to the destination is calculated based on the information in the road map DB 54c, and the estimated travel time Is added to the scheduled start date and scheduled departure time to estimate the scheduled end date and estimated arrival time (S123), and the process proceeds to S124.

  On the other hand, as a result of the process of S122, for the movement schedule for which the scheduled start date and the scheduled departure time cannot be specified, the process of S123 is skipped and the process proceeds to S124. If it is determined as a result of the process in S121 that there is no movement schedule whose scheduled end date and estimated arrival time are unknown, the process proceeds to S124.

  In the process of S124, the estimated movement schedule is registered in the schedule DB 54e. Thereby, a movement schedule is estimated based on the conversation voice data and schedule book data acquired from the mobile phone 10, and the conversation voice data in the vehicle acquired by the microphone 63, and the schedule DB 54e is updated. Then, after the process of S124, the schedule DB update process is terminated.

  Next, a destination / behavior estimation process executed by the CPU 51 of the navigation device 50 will be described with reference to FIG. FIG. 12 is a flowchart showing the destination / behavior estimation process. This process is performed when the estimated state flag is not “estimated” in the main process shown in FIG. 8, that is, the estimated state flag is “unestimated” or “re-estimated”, and the estimated destination is still estimated. This is executed when the estimated destination is not re-estimated or when it is necessary to re-estimate the estimated destination (see S58 in FIG. 8), specified by the boarding analysis process shown in FIG. 10, and stored in the boarding information data area 53b. This is a process of estimating the estimated destination from the travel schedule registered in the schedule DB 54e based on the information on the number of passengers, date and time of boarding, information on the driver and passengers.

  In this destination / behavior estimation process, first, it is determined whether or not the estimated state flag is “re-estimated” (S131). If the estimated state flag is not “re-estimated” (S131: No), the estimated state flag is determined. Since the flag can be determined to be “unestimated”, the process proceeds to S132, and normal estimation destination estimation processing is performed.

  In the process of S132, based on the boarding date and time, the driver and passenger information stored in the boarding information data area 53b, the boarding date and the names of the driver and the passenger are used as search keywords, and the corresponding information is obtained from the schedule DB 54e. All the movement schedules (schedules) to be searched are searched (S132). For example, if the boarding date is February 1, 2008 and the person “A” appears as a driver, the boarding date “February 1, 2008” and the driver “A” are used as search keywords. As a result of the processing of S132, the movement schedules whose database numbers 54e1 are “1” and “8” are extracted.

  Then, as a result of the search by the processing of S132, it is determined whether or not there is a movement schedule (plan) scheduled to end on the boarding date (S133), and if there is a movement schedule (plan) scheduled to end on the boarding date ( (S133: Yes), the estimated type flag 53a is set to "D" (S134), and the process proceeds to S135. By setting the estimated type flag 53a to “D”, it is indicated that the estimated destination estimated in the subsequent processing is scheduled to end on the boarding date, and the destination / action proposal shown in FIG. In the process, control is performed so that the estimated destination scheduled to end on the day of boarding is proposed to the passenger at an appropriate timing.

  On the other hand, as a result of the process of S133, if there is no travel schedule (scheduled) scheduled to end on the boarding date (S133: No), then the predetermined number of days and time from the boarding date and time stored in the boarding information data area 53b Within the range, the schedule DB 54e is searched for a movement schedule (schedule) that extends from the scheduled start date 54e3 to the scheduled end date 54e4 (S137). For example, when the boarding date and time is February 3, 2008, 17:00, and the predetermined number of days and time is one week, the search range is from February 3, 2008, 17:00 to February 10, 2008, 17:00. The movement schedule with the database number 54e1 being “3” is extracted as the movement schedule that crosses the day by the process of S135.

  Then, as a result of the search by the process of S137, it is determined whether or not there is a travel schedule (planned) that crosses days (S138). If there is such a travel schedule (S138: Yes), the estimated type flag 53a is set to “ F ”is set (S134), and the process proceeds to S135. By setting the estimated type flag 53a to “F”, it is indicated that the estimated destination estimated in the subsequent processing is to be moved across days within several days. In the destination / behavior suggestion process shown, control is performed so that an estimated destination moving across the day is proposed to the passenger at an appropriate timing.

  In the process of S135, the search results obtained by the process of S132 or S137 are sorted in the following priority order. First, the degree of coincidence between the person registered in the person 54e8 corresponding to each movement schedule in the schedule DB 54e and the driver and passenger information stored in the boarding information data area 53b is determined, and the coincidence is determined. Sorting is performed in descending order (S135 (a)).

  Here, when all the drivers and passengers stored in the boarding information data area 53b are registered in the person 54e8 corresponding to each movement schedule, the number of passengers stored in the boarding information data area 53b is also considered. When the number of persons registered in the person 54e8 corresponding to each movement schedule in the schedule DB 54e is equal to the number of passengers stored in the boarding information data area 53b, that is, the person 54e8 corresponding to each movement schedule in the schedule DB 54e When no person other than the driver and the passenger stored in the information data area 53b is registered, it is determined that the degree of coincidence is the highest.

  In this way, by setting the person 54e8 as the first priority for sorting, the estimated destination can be estimated from the travel schedule in which the person actually on board is registered, so the estimated destination was proposed. In this case, the possibility that the estimated destination is accepted by the passenger can be increased.

  Next, secondly, the degree of coincidence between the scheduled departure time 54e6 corresponding to each travel schedule in the schedule DB 54e and the boarding date and time stored in the boarding information data area 53b is determined, and sorting is performed in descending order of the degree of coincidence (S135). (B)). Thus, by setting the scheduled departure time 54e6 as the second priority for sorting, the estimated destination can be estimated from the travel schedule of the scheduled departure time that is closer to the actual boarding date and time, so the estimated destination is proposed. If this happens, the possibility of being accepted by the passenger can be increased.

  Next, thirdly, the information source 54e7 corresponding to each movement schedule in the schedule DB 54e is sorted in the order of "schedule book", "phone", and "conversation" ((c) of S135). Here, when the information source of the movement schedule is “schedule book”, the reliability is highest because the movement schedule is a schedule directly input to the mobile phone 10 by the user. In addition, when talking about schedules on the phone, and often speaking in an orderly manner, if the information source of the travel schedule is "phone", the reliability is better than the "schedule book". But lower than “conversation”.

  Therefore, the estimated destination is estimated from the highly reliable travel schedule by sorting the information source 54e7 corresponding to each travel schedule in the schedule DB 54e in the order of "schedule book", "phone", and "conversation". Therefore, when the estimated destination is proposed, the possibility of being accepted by the passenger can be increased.

  Then, as a result of the sorting by the process of S135, the destination registered in the destination 54e2 of the travel schedule (scheduled) corresponding to the top is read from the schedule DB 54e and set as the estimated destination (S136). Thereafter, the process proceeds to S144.

  On the other hand, if the estimated state flag is “re-estimated” as a result of the process of S131 (S131: Yes), the process proceeds to S140, and the estimated destination is estimated again. Further, when there is no movement schedule (scheduled) that crosses the day as a result of the process of S138 (S138: No), the process proceeds to S140.

  In the processing after S140, the estimated destination is estimated without considering the schedule for moving to the destination. Thus, when the estimated destination is estimated again based on the result of the process of S131, the estimated destination candidate criteria are set loosely, so that the estimated destination can be estimated flexibly. Further, when the processing after S140 is performed based on the result of the processing of S138, there is no travel schedule scheduled to end at the time of boarding in the schedule DB, and the date within a predetermined number of days and time from the boarding date and time. Even if there is no plan to cross over, it is possible to estimate some estimated destination.

  In the process of S140, the estimated type flag 53a is set to “T”. Thereby, it is shown that the estimated destination estimated in the subsequent processing is estimated without considering the schedule, and the schedule is not considered in the destination / behavior proposal processing shown in FIG. The control is performed so that the estimated destination estimated in the above is proposed to the passenger at an appropriate timing.

  Next, based on the registration date 54e9 in the schedule DB 54e, the schedules registered within a predetermined period (for example, within two weeks before the boarding date) are searched (S141), and the search results are sorted in the following priority order ( S142).

  First, the degree of coincidence between the person registered in the person 54e8 corresponding to each movement schedule in the schedule DB 54e and the driver and passenger information stored in the boarding information data area 53b is determined, and the coincidence is determined. Sort in descending order (S 142 (a)). In this sort, similarly to (a) in the sort process of S135, the degree of coincidence is determined in consideration of the number of passengers stored in the boarding information data area 53b. In this way, by setting the person 54e8 as the first priority for sorting, the estimated destination can be estimated from the travel schedule in which the person actually on board is registered, so the estimated destination was proposed. In some cases, the possibility of being accepted by the passenger can be increased.

  Second, the degree of coincidence with the history of the passenger / behavior history DB 54f is determined and sorted in descending order of degree of coincidence (S142 (b)). Specifically, for each destination heading for the past registered in the passenger / behavior history DB 54f, the number of times, the time, the time, the driver and the passenger's tendency toward the destination are analyzed. From the result, it is determined that the movement schedule having a tendency close to the boarding information (boarding date and time, driver and passenger information) stored in the boarding information data area 53b and having a large number of headings is regarded as having a high degree of coincidence. As a result, the estimated destination can be estimated from the travel schedule that matches the past behavior history trend and the destinations with the most frequent destinations are registered. The possibility of being accepted by a person. Therefore, the estimated destination can be estimated more accurately from the conversation voice and proposed.

  Then, as a result of the sorting in S142, the destinations registered in the destination 54e2 of the travel schedule (planned) corresponding to the first to third are read from the schedule DB 54e, and all of them are set as estimated destinations ( S143). If the estimated state flag 53a is “reset”, in the process of S143, the estimated destination is set except for the estimated destination estimated previously.

  Thereafter, the process proceeds to S144. Here, the reason why the three travel schedules are set as the estimated destinations is that the estimated destinations are estimated without considering the schedule, so only by setting one estimated destination, This is to increase the possibility of being accepted by the passenger by setting three estimated destinations because the possibility of being accepted by the passenger may be reduced.

  In the process of S144, the route from the position (home position) indicated by the home address registered in the user information registration unit 54d1 of the passenger information DB 54d to the estimated destination estimated by the process of S136 or S143 is searched, Further, the route from the starting position indicated by the position information stored in the search starting data area 53c to the estimated destination estimated by the process of S136 or S143 is searched. When a plurality of estimated destinations are estimated by the processing of S143, a route search from the home position and the starting position is performed for each estimated destination. The result of this route search is used when it is determined whether or not the estimated destination is proposed by the destination / behavior proposal processing (FIG. 13).

  Then, the estimated state flag is set to “estimated” (S145), and the destination / behavior estimation process is terminated. By setting the estimated state flag to “estimated”, since the execution of the destination / behavior estimation process is skipped in the main process (see FIG. 8), the estimation of the estimated destination is useless. Can be avoided.

  Next, with reference to FIG. 13, a destination / behavior proposal process executed by the CPU 51 of the navigation device 50 will be described. FIG. 13 is a flowchart showing this destination / behavior proposal processing. As described above, this destination / behavior proposal process is executed when the proposal process flag is off in the main process shown in FIG. 8 (see S60 in FIG. 8), and the purpose shown in FIG. This is a process of proposing the estimated destination estimated by the ground / behavior estimation process to the passenger at an appropriate timing.

  In this destination / behavior proposal processing, first, it is determined whether or not the estimated type flag 53a is “N” (S150). If it is “N” (S150: Yes), the estimated destination is not set. This destination / behavior proposal process is terminated. On the other hand, if the estimated type flag 53a is not “N” (S150: No), it is then determined whether or not the estimated type flag 53a is “D” (S151). And if it is "D" (S151: Yes), the proposal timing of the estimated destination scheduled to arrive on the day will be controlled in the subsequent processing.

  First, it is determined from the output signal from the touch panel 59 or the operation key 60 whether or not the navigation device 50 has been operated (S152). As a result, if there is an operation on the navigation device 50 (S152: Yes), a process of immediately proposing the estimated destination to the passenger is executed (S153). The process of proposing the estimated destination is performed by controlling the LCD 58 to display information on the estimated destination on the LCD 58. Thereby, the information about the estimated destination is displayed on the LCD 58, and the estimated destination is proposed to the passenger.

  Thus, when the estimated destination is scheduled to arrive on the day of boarding, the estimated destination is agreed by the passenger by proposing the estimated destination at the timing when the navigation device 50 is operated. The possibility can be increased. Thereby, an estimated destination can be proposed at an appropriate timing.

  Next, the proposal process flag is turned on (S154), and the destination / action proposal process is terminated. By turning on the proposal process flag, the execution of the destination / behavior proposal process is skipped in the main process (see FIG. 8). Further, in the guidance process (see FIG. 14), it is determined whether or not the passenger has accepted the estimated destination proposed by the process of S153, and if accepted, route guidance is performed using the estimated destination as the destination. .

  On the other hand, if it is determined that there is no operation on the navigation device 50 as a result of the process of S152 (S152: No), then, after the ignition switch of the vehicle is turned on, the vehicle travels a predetermined distance or a predetermined time elapses. It is determined whether or not (S155). If it is determined that the vehicle has not traveled the predetermined distance and the predetermined time has not elapsed (S155: No), the destination / behavior proposal processing is terminated as it is.

  On the other hand, if it is determined that the vehicle has traveled a predetermined distance or that a predetermined time has passed (S155: Yes), it is further estimated from the home position searched by the process of S144 of the destination / behavior estimation process shown in FIG. Whether at least one of the route to the destination and the route from the starting position to the estimated destination is the current position of the vehicle on the route or within a predetermined distance from the route. Judgment is made (S156).

  If the current position of the vehicle exists on the route or within the predetermined distance range from the route (S156: Yes), it can be determined that the vehicle is traveling toward the estimated destination, so the process of S153 Then, the estimated destination is proposed, the proposal process flag is turned on (S154), and the destination / action proposal process is terminated.

  As described above, when the estimated destination is scheduled to arrive on the day of boarding, even if the navigation device 50 is not operated, the vehicle travels for a predetermined time or a predetermined distance after the ignition switch is turned on. If the estimated destination is proposed at the timing, the possibility of the destination being agreed by the passenger can be increased. Therefore, an estimated destination can be proposed at an appropriate timing.

  On the other hand, if the current position is not on the searched route or within the predetermined distance range from the route as a result of the processing of S156 (S156: No), the estimated state flag provided in the RAM 53 is set to “reset”. Then, the estimated type flag 53a is set to “N” (S157), and the destination / behavior proposal process is terminated. By setting the estimated state flag to “reset”, the estimated destination is estimated again by the destination / behavior estimation process.

  Thus, in this embodiment, a route from the home position to the estimated destination and a route from the starting position to the estimated destination are searched in advance, and at least one of the routes By determining whether or not the current position of the vehicle exists within a predetermined distance range from the route, it is determined whether or not the vehicle is traveling toward the estimated destination. If it is determined that the vehicle is traveling toward the estimated destination, the estimated destination is proposed. On the other hand, if it is determined that the vehicle is not traveling toward the estimated destination, Proposal is not made. Therefore, the destination desired by the passenger can be accurately proposed.

  On the other hand, if the estimated type flag 53a is not “D” as a result of the process of S151 (S151: No), it is determined whether the estimated type flag 53a is “F” (S158). And if it is "F" (S158: Yes), the proposal timing of the estimated destination scheduled to be moved over several days within several days is controlled in the subsequent processing. First, it is determined from the output signal from the touch panel 59 or the operation key 60 whether or not the navigation device 50 has been operated (S159).

  As a result, if there is no operation on the navigation device 50 (S159: No), the destination / behavior proposal processing is terminated as it is. On the other hand, if there is an operation on the navigation device 50 (S159: Yes), it is further determined whether or not the current time is within a predetermined time range from the “scheduled start date” and “scheduled departure time” to the estimated destination. (S160). Then, if the current time is not within the predetermined time range from the “scheduled start date” and “scheduled departure time” to the estimated destination (S160: No), the destination / action execution process is terminated as it is. Further, if the current time is within a predetermined time range from the “scheduled start date” and “scheduled departure time” to the estimated destination (S160: Yes), a process of proposing the estimated destination to the passenger is executed. (S161) Further, the proposal process flag is turned on (S162), and the destination / action proposal process is terminated.

  Here, if the estimated destination is to be moved across the day, the passenger may act earlier than the scheduled start date, and the action spanning several days will be a long distance run There is a high possibility that the passenger uses the navigation device 50. Therefore, in the case where the estimated destination is scheduled to be moved across the day, if the estimated destination is proposed at the timing when the navigation device 50 is operated, there is a possibility that the destination is agreed by the passenger. Can be increased. Therefore, the estimated destination can be proposed at an appropriate timing.

  On the other hand, if the estimated destination is intended to be moved across days, the passenger may act earlier than the scheduled start date, but far more than the scheduled start date and scheduled departure time. The previous action may be for another destination. Therefore, when the estimated destination scheduled over several days is estimated, the navigation device 50 is operated, and the current time is a predetermined time from the scheduled start date and scheduled departure time to the estimated destination. If the estimated destination is proposed at a timing that falls within the range, the possibility that the estimated destination is agreed by the passenger can be further increased. Therefore, the estimated destination can be proposed at an appropriate timing.

  On the other hand, if the estimated type flag 53a is not “F” as a result of the process of S158 (S158: No), the estimated type flag 53a is “T”. Control the estimated timing of the estimated destination estimated without considering it. First, each route from the home position to three estimated destinations searched by the processing of S144 of the destination / behavior estimation process shown in FIG. 12 and each route from the starting position to the three estimated destinations are searched. In at least one of the routes, it is determined whether or not the current position of the vehicle exists on the route or within a predetermined distance range from the route (S163).

  And when there is no current position of the vehicle on any route or within a predetermined distance range from the route (S163: No), it can be determined that the vehicle is not heading to any estimated destination, End the destination / action proposal process. As a result, it is possible to prevent an estimated destination from being inappropriate from being proposed to the passenger.

  On the other hand, when the current position of the vehicle exists on any route or within a predetermined distance range from the route (S163: No), the vehicle may be traveling toward the estimated destination corresponding to the route. Since it can be determined that there is a characteristic, the process proceeds to S164.

  As described above, a route from the home position and a route from the starting position are searched in advance for a plurality of estimated destinations, and at least one of the routes is determined on or from the route. By determining whether or not the current position of the vehicle is within the distance range, it is possible to determine whether or not the vehicle is traveling toward any estimated destination. When it is determined that the vehicle is traveling toward one estimated destination, the estimated destination can be proposed, so that the destination desired by the passenger can be proposed more accurately.

  In the process of S164, the current time indicated by the timing circuit 51a is the scheduled start date, scheduled departure time, scheduled end date, and estimated arrival date registered for the estimated destination where the vehicle may be heading. Based on one of the times, it is determined whether it is appropriate. If no estimated start date, scheduled departure time, scheduled end date, or estimated arrival time are registered for the estimated destination where the vehicle may be heading, the determination in S164 is skipped. The process proceeds to S165 as it is.

  If the current time is not appropriate as a result of the process of S164 (S164: No), there is a high possibility that the vehicle is not traveling toward the estimated destination, and the destination / behavior proposal process is terminated as it is. To do. As a result, it is possible to prevent an estimated destination from being inappropriate from being proposed to the passenger. On the other hand, if the current time is appropriate (S164: Yes), there is a higher possibility that the vehicle is heading toward the estimated destination, and therefore processing for proposing the estimated destination to the passenger is executed (S165). Further, the proposal process flag is turned on (S166), and the destination / action proposal process is terminated.

  As described above, when the estimated destination is not intended to arrive on the day of boarding and is not scheduled to be moved across the day, the current position and current time of the vehicle are determined based on the current position and the estimated purpose. Since the estimated destination is proposed at a timing determined to be appropriate in relation to the ground, the possibility that the estimated destination is agreed by the passenger can be increased. Therefore, the destination desired by the passenger estimated from the voice can be proposed at an appropriate timing.

  As described above, since the destination / action proposal process is executed by the CPU 51, the timing for proposing the estimated destination is controlled according to the scheduled action schedule of the estimated destination. It can be done according to the schedule of action. Here, the voice about the movement schedule of an arbitrary date is included in the voice uttered outside the vehicle. Therefore, by performing the estimation of the estimated destination in accordance with the scheduled action schedule, the destination desired by the passenger can be proposed from the voice at an appropriate timing. Therefore, the destination / behavior estimation process (see FIG. 12) accurately estimates the destination desired by the passenger from the voice, and the destination / action proposal process proposes the estimated destination at an appropriate timing. It can be performed.

  Next, the guidance process executed by the CPU 51 of the navigation device 50 will be described with reference to FIG. FIG. 14 is a flowchart showing this guidance processing. This process is executed in the main process shown in FIG. 8 (see S61 in FIG. 8), and is a process for performing route guidance to the registered destination. Further, when an estimated destination is proposed to the passenger by the destination / behavior proposal process (see FIG. 12), if the estimated destination is accepted, route guidance is performed using the estimated destination as the destination. .

  In this guidance process, first, it is determined whether or not the proposal process flag is ON (S171). If the proposal processing flag is on (S171: Yes), the estimated destination is proposed to the passenger by the destination / action proposal processing (see FIG. 13), and then the passenger is proposed. It is determined whether the estimated destination has been accepted (S172). The determination as to whether or not the request has been accepted is made, for example, based on whether or not the passenger has operated the “agree” button, which is displayed at the same time when information regarding the estimated destination is displayed on the LCD 58, via the touch panel 59. . If it is determined that the passenger operates the “Agree” button and has accepted the proposed estimated destination (S172: Yes), the estimated destination is registered as the actual destination and the current position of the vehicle After searching for a route from the destination to the destination, the route guidance is performed through display on the LCD 58 (S173).

  Next, it is determined whether or not the destination has been registered (S174). If the destination has not been reached (S174: No), the guidance process is terminated as it is. On the other hand, when it is determined that the vehicle has arrived at the destination (S174: Yes), the current destination, departure date, departure time, arrival time, driver and passenger information are registered in the passenger / action history DB 54f. At the same time, if there is a movement schedule whose scheduled start date has passed in the schedule DB 54e, it is registered in the passenger / action history DB 54f as a canceled schedule, and the passenger / action history DB 54f is updated (S175). Then, the guidance process ends.

  Thus, by updating the passenger / behavior history DB 54f, when the estimated destination is estimated in the destination / behavior estimation process (see FIG. 12) from the next time onward, the past passenger / behavior history is recorded. From this tendency, it is possible to make it easier to estimate the destination to which the passenger may go.

  On the other hand, as a result of the processing in S172, the passenger does not accept the proposed estimated destination by not operating the “agree” button or by operating the “disagree” button displayed at the same time as the “agree” button. (S172: No), the estimation state flag provided in the RAM 53 is set to “re-estimation”, the estimation type flag 53a is set to “N” (S176), and the proposal processing flag is set to OFF. (S177), and this guidance process is terminated.

  By setting the estimated state flag to “reset” by the process of S176, the estimated destination is estimated again by the destination / behavior estimation process (see FIG. 12). Also, the destination / behavior proposal process (see FIG. 13) is executed again by turning off the proposal process flag by the process of S177, and the destination / behavior estimation process (see FIG. 12) is executed again. A reestimated estimated destination is proposed. Further, the processes of S178 and S179 described below are executed until an estimated destination is proposed.

  That is, if it is determined by the processing of S171 that the proposal processing flag is off (S171: No), the estimated destination is not proposed by the destination / behavior proposal processing (FIG. 13). Next, it is determined whether the passenger has registered the destination by operating the touch panel 59 or the operation key 60 (S178). When it is determined that the passenger has registered the destination (S178: Yes), the route from the current position of the vehicle to the registered destination is searched, and the route guidance is performed through display on the LCD 58 ( S179). Thereby, while the estimated destination is not proposed, the registration of the destination by the passenger can be accepted, and the route guidance to the destination can be provided to the passenger.

  Then, after the process of S179, the process proceeds to the above-described process of S174, and if it has not arrived at the destination (S174: No), the guidance process is terminated as it is, and if it arrives at the destination (S174: Yes). Then, the passenger / action history DB 54f is updated (S175), and the guidance process is terminated. Moreover, as a result of the process of S178, when it is determined that the passenger has not registered the destination (S178: No), the guidance process is terminated as it is.

  As described above, in the navigation system 1 and the navigation apparatus 50 according to the present embodiment, the voice generated outside the vehicle is a conversation voice by a telephone function call of the mobile phone 10 or around the mobile phone 10. A conversation voice is recorded by the mobile phone 10. The conversation voice data of the conversation voice recorded by the mobile phone 10 is transferred to the navigation device 50, and the conversation voice data is analyzed by the voice recognition processor 64 in the navigation device 50, and the movement schedule is based on the analysis result. Is estimated. Thereby, a passenger's destination can be estimated based on the content of the sound emitted outside the vehicle.

  Here, the destination on the vehicle is usually determined in a conversation outside the vehicle before boarding. Therefore, the destination desired by the passenger is estimated based on the content of the voice emitted outside the vehicle, and the estimated destination is displayed on the LCD 58, so that the destination desired by the passenger can be determined from the voice. Estimates and suggestions can be made accurately.

  Moreover, when there is boarding in a vehicle, boarding date and time, the number of passengers, a driver, and a passenger are specified as boarding information. The destination desired by the passenger is estimated based on the specified boarding information and a keyword that can specify the place, date, and person extracted by the speech recognition processor 64. This makes it suitable for the vehicle's boarding situation (boarding date / time, number of passengers, driver and passengers) based on keywords that can specify the location, date / time, and person included in the voice, from various types of audio. Can be estimated as the destination desired by the passenger. Therefore, the destination desired by the passenger can be estimated more accurately from the voice and proposed.

  In addition, a movement schedule is estimated based on a keyword that can identify the place, date, and person extracted by the voice recognition processor 64, and this movement schedule is registered in the schedule DB 54e. When a topic related to an action schedule is spoken or when a topic related to an action schedule is spoken in each of a plurality of conversational voice data, a movement schedule corresponding to each action schedule is generated, and added to the schedule DB 54e as needed and stored. Can be kept. Therefore, it is possible to estimate a place suitable for the boarding situation of the vehicle (boarding date and time, number of passengers, driver and passengers) from the travel schedule registered in the schedule DB 54e, so that the passenger desires from the voice. The destination can be estimated and proposed more accurately.

  As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the above-described embodiments, and various modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above-described embodiment, the case where conversation voice recording is performed by the mobile phone 10 has been described. However, the present invention is not necessarily limited to this, and various portable devices such as a PDA (Personal Digital Assistant) and an IC recorder. The conversation voice may be recorded, and the conversation voice data recorded from these devices may be transferred to the navigation device 50. Moreover, it is not necessarily limited to a portable apparatus, What is necessary is just to be provided outside the vehicle and can record a conversation voice. For example, the conversation voice in the home may be recorded by a home device installed in the house such as audio, and the recorded conversation voice data may be transferred from the home device to the navigation device 50.

  In the above-described embodiment, the description has been given of the case where the navigation device 50 acquires the conversation voice recorded by the mobile phone 10, analyzes the conversation voice, and estimates and proposes the estimated destination. It is not limited to. For example, these processes may be performed by an in-vehicle device other than the navigation device 50, such as an AV playback device. Further, these processes may be performed by a server installed inside or outside the vehicle.

  In this case, control up to the estimated destination proposal timing is performed by the in-vehicle device or a server installed inside or outside the home, and an instruction signal instructing the destination proposal at the proposed timing is sent to the in-vehicle device. Or a server installed inside or outside the house may be transmitted to the navigation device 50 provided in the vehicle, and the navigation device 50 is configured to perform the estimated destination proposal process according to the instruction signal. May be.

  Further, the navigation device 50 may be configured to determine whether or not the passenger has accepted the estimated destination, and to transmit the acceptance result to the in-vehicle device or a server installed inside or outside the house. The in-vehicle device or the server installed inside or outside the home may be configured to finish the estimation of the estimated destination or to estimate again based on the acceptance result transmitted from the navigation device 50. Good.

  Furthermore, the navigation device 50 may be configured so that information on the current position of the vehicle is transmitted from time to time to a vehicle-mounted device or a server installed inside or outside the home. The server may control the estimated timing of the estimated destination based on the information on the current position of the vehicle transmitted from the navigation device 50, or may update the passenger / action history DB 54f.

  Moreover, although the said embodiment demonstrated the case where recording of a conversational voice and estimation and a proposal of an estimated destination were each performed by another apparatus (the mobile telephone 10 and the navigation apparatus 50), it is not necessarily restricted to this. is not. For example, one device such as a home server may perform from recording of conversational speech to controlling the estimated timing of the estimated destination.

  In the above embodiment, the case where the mobile phone 10 and the navigation device 50 correspond to Bluetooth and transmit the conversation voice data and schedule book data of the mobile phone 10 by the Bluetooth method has been described, but the present invention is not necessarily limited thereto. The cellular phone 10 and the navigation device 50 may be adapted to WLAN (Wireless Local Area Network), and conversation voice data and schedule book data may be transmitted from the cellular phone 10 by the WLAN system. Further, conversation voice data and schedule book data may be transmitted from the mobile phone 10 by other wireless communication methods.

  In addition, conversation voice data and schedule book data may be transmitted from the cellular phone 10 to the cellular phone 10 and the navigation device 50 by wire via a LAN cable, a USB (Universal Serial Bus) cable, and other dedicated cables. . In addition, the mobile phone 10 is provided with a male type USB connector, the navigation device 50 is provided with a female type USB connector, and by directly connecting them, conversation voice data and schedule book data are transmitted from the mobile phone 10. Also good.

  In the above embodiment, a case has been described in which a connection request is transmitted from the navigation device 50 to the mobile phone 10 to establish a connection between the navigation device 50 and the mobile phone 10, but the present invention is not necessarily limited thereto. The connection request may be transmitted from the mobile phone 10 to the navigation device 50. In this case, for example, when the user operates the touch panel 22 or the operation key 23 to instruct the mobile phone 10 to transmit conversation voice data in accordance with the instruction from the user, the mobile phone 10 transmits to the navigation device 50. On the other hand, a connection request may be transmitted.

  In the above embodiment, the case where conversation voice data and schedule book data recorded by the mobile phone 10 are stored in the flash memory 14 has been described, but the present invention is not necessarily limited thereto. For example, when the mobile phone 10 is provided with a memory card slot so that the memory card can be inserted, the recorded conversation voice data and schedule book data may be stored in the memory card.

  In this case, if the navigation device 50 is also provided with a memory card slot and conversation voice data and schedule book data are stored in the memory card inserted in the memory card slot, the data is read from the memory card. Alternatively, it may be stored in the conversation voice data area 54a or the schedule book data area 54b of the navigation device 50.

  In the above embodiment, a case has been described in which the pressure sensor 62 is provided at each seat position of the seat, and the number of passengers is detected from the number of pressure sensors 62 to which a pressure equal to or higher than a predetermined level is applied. Absent. For example, the image recognition processor 65 determines whether or not a face image is included in each image by using an image captured by the camera 70 provided for each seat position, and the image including the face image is determined. The number of passengers may be detected by counting the number. Further, a sensor for detecting whether or not the seat belt is closed may be provided on the buckle of the seat belt, and the number of passengers may be detected by counting the number of closed seat belts. The voice data acquired from the microphone 63 may be analyzed by the voice recognition processor 64, and the number of passengers may be detected from the number of types of voice included in the voice.

  In the above embodiment, identification of the driver or passenger is performed by pattern matching between the face image data captured by the camera 70 and the face image data stored in the “face image” information of the passenger information DB 54d. Although it was performed by comparing, it is not necessarily limited to this. For example, for each person registered in the passenger information DB 54d, a facial feature amount is registered, and the image recognition processor 65 extracts the feature amount from the face image data captured by the camera 70, The person having the feature quantity closest to the extracted feature quantity may be specified with reference to the passenger information DB 54d.

  In addition, the driver and passengers may be specified by sound instead of images. In this case, the voice feature amount is registered for each person registered in the passenger information DB 54 d, and the voice recognition processor 64 uses the voice data acquired from the microphone 63 to characterize the voices of the driver and passengers. The amount may be extracted, and the person having the feature amount closest to the extracted feature amount may be specified with reference to the passenger information DB 54d.

  In the above embodiment, the case where the destination, the scheduled start date, the scheduled end date, the scheduled arrival time, the scheduled departure time and the person are estimated as the movement schedule from the conversation voice data and the schedule book data has been described. Thus, the number of passengers may be estimated, and this number of passengers may be registered in the schedule DB 54e. Then, the estimated destination may be estimated by directly comparing the number of passengers stored in the boarding situation data area 53b and the number of passengers in each movement schedule of the schedule DB 54e. As a result, the conditions for estimating the estimated destination increase, so that a more accurate estimated destination can be proposed according to the boarding situation.

  In the above-described embodiment, the case where the estimated destination is estimated from the information about the boarding date and time, the number of passengers, the driver and the passengers as the boarding information has been described. However, the present invention is not necessarily limited to this. The estimated destination may be estimated based on at least one of the passengers (driver and passenger). If the number of boarding information used for estimating the estimated destination is reduced, the load related to the estimation process can be reduced.

  In the above embodiment, the scheduled start date 54e3, the scheduled end date 54e4, the scheduled arrival time 54e5, the scheduled departure time 54e6, the information source 54e7, the person 54e8, and the registration date 54e9 are registered as the schedule DB 54e corresponding to the destination 54e2. Although the case has been described, the present invention is not necessarily limited to this, and at least one of them and the number of passengers may be registered. If the number of items registered in the schedule DB 54e is reduced, it is possible to reduce the load of the process for updating the schedule DB 54e and the process for estimating the estimated destination.

  In the above-described embodiment, the case where the estimated destination is proposed by being displayed on the LCD 58 of the navigation device 50 has been described. However, the present invention is not necessarily limited to this, and the name of the estimated destination is output from the speaker 61 to the outside by voice. You may make it output (sound emission). As a result, the driver can receive the estimated destination proposal without looking at the LCD 58, and safety for the driver can be taken into consideration.

  Further, in the above embodiment, the estimated destination proposal is accepted by detecting whether or not the “agreement” button displayed on the LCD 58 is operated via the touch panel 59 in response to the estimated destination proposal. However, the present invention is not necessarily limited to this, and it may be determined whether or not the estimated destination proposal has been accepted based on the voice uttered by the passenger. For example, if the passenger issues “OK”, it is determined that the estimated destination proposal has been accepted, and if the passenger issues “other?”, The estimated destination proposal is not accepted. You may decide that Thereby, the driver can express the acceptance of the proposal of the estimated destination without operating the touch panel 59, and safety for the driver can be taken into consideration.

  In the above embodiment, the estimated number of estimated destinations is set to one or three according to the situation. However, the number of estimated destinations is not necessarily limited to this, and the number of estimated destinations may be set to an arbitrary number. Good.

  In the above embodiment, the position information of the current position of the vehicle at the time when the ignition switch is turned on is set as the position information of the starting position indicated by the search starting point data area 53c used in the route search to the estimated destination. However, instead of this, or in combination with this, when the passenger operates the touch panel 59 or the operation key 60, the position of the starting position that the passenger should store in the search starting data area 53c. Information may be set. Thereby, the starting point position used for the route search to the estimated destination can be set to a desired position by the passenger. Therefore, if the current position of the vehicle is located on the route searched from the desired position to the estimated destination or within a predetermined distance range from the route, the vehicle travels toward the estimated destination. Can be determined according to the passenger's wishes. Therefore, in such a case, the destination desired by the passenger can be proposed more accurately by proposing the estimated destination.

  In the above embodiment, when the estimated destination is scheduled to arrive on the boarding date, when the navigation device 50 is operated, the estimated destination is proposed at that timing. Propose the estimated destination only when the current position of the vehicle is on the route searched for from the home position or origin position to the estimated destination at the time of operation, or within a predetermined distance range from the route. You may do it. Thereby, the estimation destination can be proposed more appropriately.

  In the above embodiment, when the estimated destination is scheduled to arrive on the boarding date, when the navigation device 50 is operated, the estimated destination is proposed at that timing. The determination of whether or not there is an operation is omitted. In this case, it is always determined that the vehicle has traveled a predetermined distance since the ignition switch was turned on, or that a predetermined time has passed, When elapses, an estimated destination may be proposed under a predetermined condition.

  In the above embodiment, when the estimated destination is scheduled to be moved across the day, an operation on the navigation device 50 is detected, and the current time is the “scheduled start date” to the estimated destination, Although the case where the estimated destination is proposed within the predetermined time range from the “scheduled departure time” has been described, the present invention is not necessarily limited thereto. For example, when the estimated destination is scheduled to be moved across days, an operation on the navigation device 50 is detected, or the current time is “estimated start date”, “ If it is within a predetermined time range from the “departure scheduled time”, an estimated destination may be proposed.

  Here, if the estimated destination is one that is scheduled to be moved across the day, the passenger may start to act outside the predetermined date or scheduled departure time, while the current time is If it is within a predetermined time range from the scheduled date and the scheduled departure time, the possibility that the passenger is traveling toward the estimated destination is increased. Therefore, when the estimated destination is scheduled to be moved across the day, an operation on the navigation device 50 is detected, or the current time is “estimated start date”, “ If the estimated destination is within a predetermined time range from the “departure scheduled time”, it is possible to increase the possibility that the estimated destination is agreed by the passenger. Therefore, the estimated destination desired by the passenger can be proposed at an appropriate timing.
