In addition, comprehensive processing of the navigation unit 2 is performed. Comprehensive processing of the navigation unit 2 includes calculation processing of a recommended route to the destination.

  The information center 20 includes an operation center 30, an information database group 40, a vehicle information center 50, and a customer center 60. The operation center 30 includes a PBX / CTI 31 that controls a telephone line and a search system 34. The search system 34 includes a search processing terminal 32, a telephone 33, a headset 36, a monitor 38, and an input device 39. The input device 39 includes a keyboard and a mouse.

  A PBX (Private Branch Exchanger) is usually installed in a corporate building or the like, and exchanges external telephones with internal telephones and between internal telephones. CTI (Computer Telephony Integration) integrates a telephone communication system such as PBX and an information system such as a computer and a database so that they can be linked to each other. In other words, the PBX / CTI 31 controls the telephone line such as connecting a call received from the user to a vacant operator or sending a waiting voice guidance when there is no vacant operator.

  The operator working at the operation center 30 uses the telephone 33 or the headset 36 to talk with the user and confirm the destination set in the navigation unit 2 of the in-vehicle device 1. The operator uses the search processing terminal 32 to search for information on the destination heard from the user. The search processing terminal 32 is a personal computer, for example. The search system 34 is connected to a plurality of databases 41 to 45, 56 constituting the information database group 40 through a network 37 such as a LAN.

  The information database group 40 includes a location / phone information database 41, a traffic information database 42, a weather forecast database 43, various information databases 44, a guidance voice database 45, and a user profile database 56. The position / phone information database 41 stores names of various facilities such as restaurants and public facilities, position information, telephone number information, and the like. The traffic information database 42 stores traffic information such as general roads and toll roads. The weather forecast database 43 stores weather forecast information for each location. The various information database 44 stores information other than the above-described information on various facilities, traffic information, and weather information. The guidance voice database 45 stores voice data for voice guidance to the user.

For example, in the search system 34, when the destination data set in the navigation unit 2 of the in-vehicle device 1 is searched, the searched destination data is transmitted to the in-vehicle device 1 via the communication device 53. . The PBX / CTI 31 of the operation center 30 and the PBX / CTI 52 of the vehicle information center 50 are connected to the general telephone line network 55.

  The customer center 60 includes a customer registration system 62 and a customer management server 66. The customer registration system 62 performs user registration and changes of registered user personal information. A customer management server 66 connected to the customer registration system 62 is a server for managing user information.

  An Internet 63 is also connected to the network 37 to which the operation center 30, the information database group 40, the vehicle information center 50 and the customer center 60 are connected. Accordingly, the information center 20 exchanges various information with the content provider / application service provider group 64 via the Internet 63. Further, when the user performs user registration, which will be described later, it is possible to use a terminal 65 such as a personal computer connected to the Internet 63 without going through the operator of the customer center 60.

  A user who uses the vehicle information provision system in one embodiment needs to perform user registration in advance. As a first method for user registration, a mobile phone 4 and a data communication phone used when using the present system together with general information such as a user's name, address, date of birth, etc. in a predetermined application form. 7 is entered and mailed to the customer center 60 of the information center 20. After confirming the contents of the application form, the customer center 60 operator performs user registration processing on the customer management server 66 using the customer registration system 62. The registered user information is stored in the user profile database 56.

  As described above, the second method for user registration is a method of directly registering in the customer management server 66 using a terminal 65 such as a personal computer connected to the Internet 63. Further, when the in-vehicle device 1 has an online registration function, the in-vehicle device 1 can be used to directly register with the customer management server 66.

  FIG. 3 is a flowchart showing processing contents respectively performed by the in-vehicle device 1 and the information center 20 in the vehicle information providing system according to the embodiment. The process of step S10 to step S40 is a process performed on the vehicle-mounted device 1 side, and the process of step S100 to step S170 is a process performed on the information center 20 side.

  In step S <b> 10, the integrated calculation unit 22 of the navigation unit 2 determines whether the operator call switch 12 is turned on based on a signal input from the input processing unit 19. If it is determined that the operator call switch 12 is not turned on, the process waits in step S10 until it is turned on. If it is determined that the operator call switch 12 is turned on, the process proceeds to step S20.

  In step S20, a call is made to the operation center 30 of the information center 20 in the voice mode. The voice mode is a mode for the user and the operator to have a conversation. As described above, since the telephone number of the operation center 30 is registered in the communication adapter 5 in advance, when the user presses the operator call switch 12, the automatic operation is performed via the navigation unit 2, the communication adapter 5, and the mobile phone 4. A call is made to the operation center 30. At this time, the communication adapter 5 places the number “186” in front of the telephone number of the operation center 30 and makes a call. That is, since some mobile phones 4 have a function for notifying the caller number, the caller number is notified so that the information center 20 can identify the caller. Make a phone call in the form.

  Of the processes performed on the information center 20 side, the processes in steps S100 to S140 and step S180 are performed in the PBX / CTI 31 of the operation center 30. In step S100, it is determined whether there is an incoming call from the user. If it is determined that there is no incoming call, it waits in step S100 until there is an incoming call. If it is determined that there is an incoming call, the process proceeds to step S110. In step S110, caller telephone number acquisition processing is performed. At this time, if a call is received with the caller non-notification setting, and there is no caller telephone number, for example, “Caller ID is not notified” registered in the guidance voice database 45 in advance. "Is played and the telephone line is disconnected.

  In step S120, the telephone number is authenticated based on the caller telephone number acquired in step S110. This authentication is performed based on whether or not the caller telephone number is registered in the user profile database 56. In step S130 following step S120, it is determined whether or not the authentication is OK based on the result of the telephone number authentication performed in step S120. If the acquired caller telephone number is registered in the user profile database 56 and the authentication is determined to be OK, the process proceeds to step S140. On the other hand, if it is determined that the authentication is NG, the process proceeds to step S180, and a message such as “Cannot receive the service because the telephone number is not registered” registered in the guidance voice database 45 is reproduced. Disconnect the telephone line.

  In step S140, the telephone call from the user is connected to the operator who has a free telephone line, and the process proceeds to step S150. However, when there is no available line, for example, a message such as “Now, the line is busy” is registered in advance in the guidance voice database 45.

  The processing of step S150 and step S160 is performed by the search system 34. In step S150, it is determined whether or not the operator has input information necessary for searching for a destination and a search execution command has been issued. The operator listens to information such as an address for searching for a destination, a facility name, and a nearby landmark by talking with the calling user, and inputs the information to the search system 34.

  FIG. 4 is a diagram illustrating an example of a search screen displayed on the display of the search processing terminal 32 included in the search system 34. As shown in FIG. 4, a name input field 71, an address input field 72, a genre input field 73, a map display field 74, and a search start button 75 are displayed on the display of the search processing terminal 32. The name input field 71 is a field for inputting the name of a facility or the like, and the address input field 72 is a field for inputting an address. The genre input field 73 is a field for inputting the genre of the destination. For example, “restaurant”, “park”, “gas station”, and the like can be input. The operator may input only one of the information input columns 71 to 73, or may input two or all of the columns.

  The map display field 74 is a field for displaying a map around the place searched by the search system 34. The search start button 75 is a button operated by an operator when starting a search for a destination.

  In step S150, information for searching for a destination is input to at least one of the name input field 71, the address input field 72, and the genre input field 73, and the search start button 75 is pressed. If it determines, it will progress to step S160, otherwise, it will wait in step S150.

  In step S160, the destination is searched by referring to the position / phone information database 41 based on the input information. The destination data searched by the search system 34 is saved (stored) in the user profile database 56. The data is stored in correspondence with the user information of the user who has requested data transmission.

  In step S170 following step S160, the information processing terminal 54 of the vehicle information center 50 sends the destination data stored in the user profile database 56 to the in-vehicle device 1 via the communication device 53 in the data mode. Send. The data mode is a mode for exchanging data by data communication. Here, the data is transmitted to the data communication telephone 7. Since the telephone number of the data communication telephone 7 is included in the user information registered in the user profile database 56, it is acquired from the user profile database 56 together with the destination data.

  In step S30, the in-vehicle device 1 determines whether or not the destination data transmitted by the vehicle information center 50 in step S170 has been received. Data transmitted in the data mode from the vehicle information center 50 is received via the data communication telephone 7. If it is determined that the destination data has not been received, it waits in step S30 until it is received, and if it is determined that it has been received, the process proceeds to step S40. In step S40, the destination setting process is performed on the navigation unit 2 based on the received destination data.

  In the vehicle information providing system according to the embodiment, in the case where it takes time to search for the destination, such as when the user does not clearly know the location or name of the destination, the destination is not information on the destination itself. Based on the information regarding the place, a temporary destination is determined and data of the temporary destination is transmitted to the in-vehicle device 1. As a result, a temporary destination serving as a mark of the position of the destination or the direction to the destination is set in the navigation unit 2. In parallel with the process of determining the temporary destination and transmitting it to the in-vehicle device 1, a conversation to narrow down (determine) the destination is performed between the operator and the user, and the finally determined destination Is retrieved by the retrieval system 34 and transmitted to the in-vehicle device 1. As a result, the navigation unit 2 searches for the route to the set temporary destination, that is, the route to the vicinity of the destination even during a conversation for narrowing the destination between the user and the operator. And since it displays on the monitor 3, before a destination is decided, it becomes possible to advance a vehicle to the direction of the destination.

  FIG. 5 shows a flow of processing for determining a temporary destination and transmitting it to the in-vehicle device 1, searching for data of the destination determined by the conversation between the user and the operator, and transmitting the data to the in-vehicle device 1. It is a flowchart. In the flowchart of FIG. 5, a process performed by the operator, a process performed by the search system 34, and a process performed by the information processing terminal 54 are shown. The processing from step S200 to step S280 corresponds to the processing from when the telephone from the user is connected to the operator in step S140 of the flowchart shown in FIG. 3 until the destination data is transmitted to the vehicle-mounted device 1 in step S170. To do.

  In step S <b> 200, the operator inputs the content heard through the conversation with the user to the search processing terminal 32 of the search system 34. This content is not information on the destination itself, but information on the destination. For example, when the user asks “I want to go to a bank around Tokyo Station”, “Tokyo Station” is entered in the name input field 71 displayed on the display of the search processing terminal 32. If the user does not know the detailed address of the destination but knows the name of the city, the user inputs “Atsugi City, Kanagawa Prefecture” in the address input field 72, for example. Also, when the user asks “I don't remember the name clearly, but I want to go to a large park in Yokohama,” enter “Yokohama City, Kanagawa” in the address input field 72 and enter the genre input field. Enter “park” in 73.

  That is, in the conventional system, the operator narrows down the destination by conversation with the user and then searches the destination processing data by the search processing terminal 32. In the vehicle information providing system in one embodiment, Before narrowing down the destinations by conversation with the user, information on the destination (information for determining a temporary destination) is input to the search processing terminal 32 based on the contents heard from the user. When the operator inputs information related to the destination and presses the search start button 75, the process proceeds to step S210.

  In step S210, the search system 34 searches the temporary destination data by referring to the position / phone information database 41 based on the input information. In the above-described example, when “Tokyo Station” is entered in the name input field 71, data on the Tokyo station is searched. In this case, the position of Tokyo Station is set as a temporary destination. Further, when the address is input only up to the city or town, as in the case where “Atsugi City, Kanagawa Prefecture” is input in the address input field 72, the facility or the like existing in the city or town is searched.

  In step S220 following step S210, the search result is displayed on the display of the search processing terminal 32. FIG. 6 is a diagram illustrating an example of a search result. FIG. 6 shows an example of a search result when “Atsugi City, Kanagawa Prefecture” is entered in the address input field 72, and a map of Atsugi City along with a list of facility names in Atsugi City is a map display field. 74.

  In step S250, the operator conducts a conversation with the user based on the search result displayed on the display of the search processing terminal 32, and narrows down the destination. For example, when a plurality of search results are obtained, the obtained search results are communicated to the user, or the location of the retrieved facility is communicated with reference to the map displayed in the map display column 74. . When the destination is narrowed down and determined by conversation with the user, the process proceeds to step S260. In step S260, the operator inputs information on the determined destination to the search processing terminal 32.

  The search processing terminal 32 of the search system 34 acquires temporary destination data from the position / phone information database 41 while a conversation for narrowing down the destination is being performed between the operator and the user. In the case where the input information is one facility such as “Tokyo Station”, the facility is a temporary destination, so the data of the facility is acquired. If the address is input only up to the city or town, such as “Atsugi City, Kanagawa Prefecture”, data is acquired using the center of the city or town as a temporary destination. The city / town center data may be registered in advance in the location / phone information database 41. In addition, for example, the position of a city hall or town hall can be regarded as a central location, set as a temporary destination, and data of the city hall or town hall can be acquired.

  In step S <b> 240, the information processing terminal 54 transmits the temporary destination data acquired by the search system 34 to the in-vehicle device 1 via the communication device 53. In this case, for example, flag data is added and transmitted so that it can be identified that the data to be transmitted is not the destination data but the temporary destination data.

  On the in-vehicle device 1 side, the temporary destination is set in the navigation unit 2 based on the received temporary destination data. In this case, the navigation unit 2 may search for a route to the temporary destination and display the searched route on the monitor 3, or on the map around the current location so that the direction of the temporary destination is known. An arrow indicating the direction of the temporary destination may be superimposed and displayed. FIG. 7 is a display example in which the direction of the destination is indicated by an arrow on a map around the current location. In any display method, it is preferable to display the information so that the user can know that the information displayed on the monitor 3 is information related to the temporary destination. In the display example shown in FIG. 7, by displaying “Toward Atsugi City, Kanagawa Prefecture”, the user can know that only the direction to the destination is shown.

  On the other hand, in step S270, the search processing terminal 32 of the search system 34 searches the destination data by referring to the position / phone information database 41 based on the information input by the operator in step S260. When the destination data is retrieved, the process proceeds to step S280. In step S280, the information processing terminal 54 transmits the destination data searched by the search processing terminal 32 to the in-vehicle device 1 via the communication device 53. On the in-vehicle device 1 side, the temporary destination data is erased and the destination is set in the navigation unit 2 based on the received destination data.

  In the vehicle information providing system in one embodiment, the operator of the information center 20 asks the user for information on the destination set in the navigation unit 2 mounted on the vehicle, searches for the destination, and searches the destination. In this system, a destination is set in the navigation unit 2 by transmitting the location data to the vehicle-mounted device 1, and the information center 20 uses the information related to the destination input to the search processing terminal 32 of the search system 34 by the operator. Based on this, a temporary destination is determined, data of the determined temporary destination is searched, and transmitted to the in-vehicle device 1. The in-vehicle device 1 that has received the temporary destination data sets the temporary destination in the navigation unit 2. As a result, even if the user does not clearly remember the name of the destination or the like and it takes time until the destination set in the navigation unit 2 is narrowed down by the conversation between the user and the operator, the navigation unit 2 The vehicle can be advanced with the provisional destination set at the target. That is, it takes time until the destination is set in the navigation unit 2, and it is possible to prevent a situation in which the vehicle cannot be started until the direction of the destination can be grasped.

  In the conventional vehicle information providing system, when it takes time to transmit the destination data from the information center 20 to the vehicle-mounted device 1 when the vehicle is already running, the navigation unit 2 has a destination. There may be a situation in which the vehicle has traveled a considerable distance in the direction opposite to the actual destination before the setting. However, according to the vehicle information providing system in the embodiment, the temporary destination data is transmitted and set in the navigation unit 2 before the destination data is transmitted to the vehicle-mounted device 1. By confirming the position or direction of the temporary destination set in the navigation unit 2, the vehicle can be advanced in the correct direction.

  The present invention is not limited to the embodiment described above. For example, in step S120 of the flowchart shown in FIG. 3, user authentication is performed based on a mobile phone number, but user authentication can also be performed based on a user ID issued after user registration is performed. . Further, user authentication may be performed based on the vehicle-mounted device ID unique to the vehicle-mounted device 1. In this case, as the in-vehicle device ID, for example, the serial ID is written when the in-vehicle device 1 is shipped from the factory, and the user applies the in-vehicle device serial ID on the application form when registering the user. In other words, it is only necessary that the in-vehicle device 1 used by the calling user can be specified and data of the temporary destination and the destination data can be transmitted to the specified in-vehicle device 1 when performing data communication. The user authentication method for specifying the in-vehicle device 1 is not limited to the method described above.

  In the above-described embodiment, the example in which the data communication telephone 7 for performing data communication is provided separately from the mobile phone 4 for the user to converse with the operator has been described. If it is a telephone that can communicate, only one phone need be provided.

  In the case where a temporary destination is set in the navigation unit 2, the method for displaying the route to the temporary destination on the monitor 3 and the method for displaying the direction to the temporary destination have been described as examples. However, in addition to these display methods, for example, only the roads that are supposed to pass to reach the destination among the routes to the temporary destination calculated based on the set temporary destination are displayed. It may be. When displaying the route of the temporary destination, a color different from the color used when displaying the route to the destination may be used in order to distinguish it from the route to the destination.

  When the in-vehicle device 1 receives the data of the temporary destination and the position of the temporary destination is close to the current position of the vehicle, it is determined that the position accuracy of the temporary destination is lower than the position of the destination. Thus, the position or direction of the temporary destination may not be displayed on the monitor 3. As mentioned above, when the address is input only up to the city, in order to set the center of the city as the temporary destination, if the current location of the vehicle is in the city, the location accuracy of the temporary destination is Lower. Therefore, for example, if the position of the temporary destination is within a predetermined distance from the current position of the vehicle, it is determined that the position accuracy of the temporary destination is low and information on the temporary destination is not displayed. It is possible to prevent the vehicle from being led in the wrong direction. In this case, it may be displayed on the monitor 3 that the position accuracy of the temporary destination is low.

  Whether the location accuracy of the temporary destination is low can be determined not on the vehicle-mounted device 1 side but on the information center 20 side. That is, if the data on the current position of the vehicle detected on the in-vehicle device 1 side is transmitted to the vehicle information center 50 in the information center 20, the vehicle information center 50 searches the temporary destination data searched for and the vehicle Based on the current position data, it can be determined whether or not the position accuracy of the temporary destination is low. In this case, if it is determined that the position accuracy of the temporary destination is low, the data of the temporary destination is not transmitted to the in-vehicle device 1, so that it is possible to prevent unusable data from being transmitted to the in-vehicle device 1.

  If the location of the temporary destination is far from the current location of the vehicle, calculate the route to the temporary destination, display the calculated route, and if the location of the temporary destination is close to the current location of the vehicle, Only the direction of the temporary destination may be displayed.

  In the above-described embodiment, an example in which a temporary destination is searched once and transmitted to the vehicle-mounted device 1 has been described as an example. However, the temporary destination search / transmission process can be performed a plurality of times. In other words, in the course of narrowing down the destination by the conversation between the user and the operator, every time a point that becomes a landmark for heading to the destination becomes clear, that point becomes the temporary destination. If set, points near the destination can be sequentially set as temporary destinations. Therefore, the in-vehicle device 1 can display information on a position closer to the destination on the monitor 3 every time data on the temporary destination is received.

  Temporary destination data and destination data retrieved by the retrieval system 34 are temporarily stored in the user profile database 56, but are not stored but are transmitted to the information processing terminal 54 of the vehicle information center 50. You may do it.

  The correspondence between the constituent elements of the claims and the constituent elements of the embodiment is as follows. That is, the search system 34 of the information center 20 constitutes temporary destination determination means and data search means, the communication device 53 constitutes transmission means and reception means, the navigation unit 2 of the in-vehicle device 1 serves as the destination setting means, and the data The communication telephone 7 constitutes receiving means. In addition, the above description is an example to the last, and when interpreting invention, it is not limited to the correspondence of the component of said embodiment and the component of this invention at all.
