Description

  The present invention relates to an in-vehicle information terminal device, an in-vehicle information control system, and an in-vehicle information control method that can match information stored in a center device and a terminal device without being conscious of a user.

  Conventionally, as an in-vehicle information control system, from an in-vehicle information terminal device that is used by a user in a vehicle or the like to receive information, the user connects to an information provider's center device that provides information, and when the user makes a request, There is a system that provides various contents from the center device to the in-vehicle information terminal device.

  In such a case, the center device (information provider) that provides the content concludes a contract with the user who provides the information and charges the user for maintenance and profit transfer of the content. At this time, the center device stores contract information with the user, and when there is a content request from the user, the contract information is confirmed and provided according to the contract.

  Furthermore, when the contract information is only available in the center device as described above, if the user wants to use the content, the terminal device once changes from the terminal device to the center device to confirm whether or not the content use contract has been completed. Since it cannot be confirmed without access, it is also possible to store the contract information also on the terminal device side so that the presence or absence of a content use contract can be confirmed only on the terminal device side.

  However, if the same contract information is held by both the in-vehicle information terminal device and the center device, the identity of both information may be lost. Therefore, it is necessary to guarantee the coincidence between the data on the terminal device and the data on the center device.

In the system for matching the shared data held in the user terminal with the shared data held in the center device, as shown in FIG. 5, when the user accesses the center device from the terminal device, the center device 10 loads the data distribution program 11 into the terminal. The data distribution program 11 activated in the terminal device 20 returns to the device 20, acquires and sends the last update date / time A of the shared data A from the data group 21, and the shared data B acquired from the base data group 13 by the center device 10. By comparing the last update date / time B and the last update date / time A and returning the update data for the shared data A that needs to be updated to the terminal device 20, the data held in the terminal device is automatically held in the center device. A system for updating data has been considered (see, for example, Patent Document 1).

  Here, the contract information is information on a contract content between the information provider and the user so that the user can receive various contents from the information provider, and the contract information is searched. The user is permitted to provide various contents by the information provider. By signing the contract, contract information is created in the center storage unit 220. For example, only a user who has this contract information can receive provision of contents such as car navigation information.

  The terminal contract information is information created on the in-vehicle information terminal device 100 side in synchronization with the contract information creation on the center device 200 side when the contract is concluded. The in-vehicle information terminal device 100 is based on the terminal contract information. However, even if it is not connected to the center apparatus 200, it is possible to confirm the contract details and grasp the usable contents.

  The user operation information refers to operation instruction information input from the operation input unit 110 of the in-vehicle information terminal device 100 by the user.

  The operation input unit 110 of the in-vehicle information terminal device 100 is configured by an input device such as a keyboard, a touch panel, and a tablet, for example, and inputs user operation information using numbers, characters, symbols, and the like. In this embodiment, it is assumed that the operation input unit 110 is configured with a keyboard, an individual deletion key for deleting information for each user, an all user deletion key for deleting information of all registered users, A selection key for selecting a user who uses the system, a contract execution key for executing a contract with an information provider, and a character key for inputting information created by the user himself / herself are provided.

  The terminal storage unit 120 is configured by, for example, a semiconductor memory, a magnetic disk, a magnetic optical disk, or the like, and is input by the terminal input information and the operation input unit 110 based on the contract information received from the center device 200 via the terminal communication unit 130. User-created information entered by a new user is recorded.

  The terminal display unit 140 includes, for example, an image processing circuit, a liquid crystal display, and the like, and displays content, user operation guidance, and input operations.

  The terminal control unit 190 is configured by, for example, a CPU, a ROM, a RAM, and the like.

The respective units of the in-vehicle information terminal device 100 are controlled such that a contract information release command is transmitted.

  Furthermore, the center storage unit 220 of the center device 200 is configured by, for example, a semiconductor memory, a magnetic disk, a magnetic optical disk, and the like, and records the contract information and contents to be provided to the user.

  The center control unit 290 is constituted by, for example, a CPU, a ROM, a RAM, and the like, and when the contract information cancellation command is received via the center communication unit 210, the contract information stored in the center storage unit 220 is canceled. Each part of this center apparatus 200 is controlled, such as performing a process.

  Next, the operation of the in-vehicle information control system according to the present embodiment will be described with reference to flowcharts shown in FIGS. In the present embodiment, the in-vehicle information terminal device 100 can perform two user registrations per contract.

  First, a user registration process in the in-vehicle information control system of the present embodiment will be briefly described with reference to FIG.

  In FIG. 2, when the in-vehicle information control system is activated, a selection screen for a user who uses the system is displayed, and the user is selected from the operation input unit 110 of the in-vehicle information terminal device 100 by the user (step) s101). When the user is selected, it is determined whether or not the in-vehicle information terminal device 100 is contracted with the information provider (step s102). Here, if it has been contracted, it is determined whether or not the selected user has been registered (step s109), and if not contracted, a contract conclusion screen is displayed (step s103).

  Next, the user waits for input of a contract execution key for performing a contract with the information provider from the operation input unit 110 of the in-vehicle information terminal device 100 (step s104), and ends the process when the contract execution key is not accepted. When the contract execution key is pressed, the center apparatus is connected (step s105). If the center device 200 can be normally connected, the contract information is created in the center device 200 and stored in the center storage unit 220. The terminal storage unit 120 of the in-vehicle information terminal device 100 also synchronizes with the contract information. The contract information is stored (step s106).

  Next, when the contract information of the center device 200 and the terminal contract information of the in-vehicle information terminal device 100 are normally created, user registration is performed (step s107). Here, the user registration process is performed by the selected user.

  If the user registration is normally performed, a content service provision screen is transmitted from the center device 200 to the in-vehicle information terminal device 100 and displayed on the terminal display unit 140 of the in-vehicle information terminal device 100 (step s108).

  In the contracted determination process (step s102) of the in-vehicle information terminal device 100, if it is contracted, it is determined whether or not the selected user has been registered (step s109). If the selected user is not registered, the user registration process (step s107) is performed. If the selected user is registered, the service screen display process (step s108) is performed. End the user registration process.

  Therefore, when using this system for the first time, after a contract with the information provider is concluded, user registration is performed with the specified user, and this system can be used. Other user registration is automatically performed and the system can be used.

  Next, information deletion processing for each user in the in-vehicle information control system of the present embodiment will be described with reference to FIG. Here, it is assumed that registration processing for one user has already been completed from the in-vehicle information terminal device 100 to the center device 200.

  In FIG. 3, first, when a user delete operation is input from the operation input unit 110 of the in-vehicle information terminal device 100 by the user (step s301), it is determined whether or not the user is under contract. The terminal contract information stored in the terminal storage unit 120 is searched and confirmed (step s302). Here, if the user is not contracting, the information erasing process in the in-vehicle information terminal device 100 is performed (step s308), and the process is terminated. If the contract is in progress, the browser is activated and connected to the center apparatus 200 (step s303).

  Next, it is confirmed whether or not the center apparatus 200 can be normally connected (step s304). If the center apparatus 200 cannot be normally connected, this process is terminated. If the center apparatus 200 is normally connected, the user is canceled (step s305). Here, the user cancellation process is performed on the contract information stored in the center storage unit 220 on the center device 200 side.

  Next, it is confirmed whether or not the user's cancellation process is normally completed in the center device 200 (step s306). If the cancellation process cannot be performed normally, the present process is terminated. If the cancellation process is performed normally, a guidance for erasing information in the in-vehicle information terminal device 100 is sent from the center device 200 to the in-vehicle information terminal device 100. (Step s307). Here, if a flag for canceling the contract on the center side is set in the terminal contract information stored in the terminal storage unit 120 of the in-vehicle information terminal device 100, communication with the center device 200 is not performed each time the user information deletion process is performed. User erasure processing can be performed. Further, after the information deletion guidance and the center cancellation processing flag are updated, the communication with the in-vehicle information terminal device 100 from the center device 200 may be disconnected.

  When receiving the information deletion guide in the in-vehicle information terminal device 100, the user deletes the information in the in-vehicle information terminal device 100 (step s308), and ends this processing.

  Through the above processing, when user information is deleted in the in-vehicle information terminal device 100, if the contract information remains on the center device 200 side without being consciously connected to the center device 200, the center device 200, the contract information on the center device 200 side is deleted, so the contract information on the in-vehicle information terminal device 100 side is deleted, and only the contract information on the center device 200 side does not remain, and the center side and the terminal side And the contract information can always be matched, and problems due to contract information inconsistency can be avoided.

Here, it is assumed that registration processing for two users has already been completed from the in-vehicle information terminal device 100 to the center device 200.

  In FIG. 4, first, when an all-user deletion operation is input by the user from the operation input unit 110 of the in-vehicle information terminal device 100 (step s401), it is determined whether or not there is a registered user who is under contract. The terminal contract information stored in the terminal storage unit 120 is searched and confirmed on the in-vehicle information terminal device 100 side (step s402). Here, if there is no user under contract, information erasure processing in the in-vehicle information terminal device 100 is performed (step s409), and the processing is terminated. If any of the registered users has a contract, the browser is activated and connected to the center apparatus 200 (step s403).

  Next, it is confirmed whether or not the center apparatus 200 is normally connected (step s404). If the center apparatus 200 cannot be normally connected, this process is terminated. If the center apparatus 200 is normally connected, the user is canceled (step s405). Here, the user cancellation process is performed on the contract information stored in the center storage unit 220 on the center device 200 side.

  Next, it is confirmed whether or not the user's cancellation processing is normally completed in the center device 200 (step s406). If the cancellation process cannot be performed normally, the present process is terminated. If the cancellation process is performed normally, a guidance for erasing information in the in-vehicle information terminal device 100 is sent from the center device 200 to the in-vehicle information terminal device 100. (Step s408). Here, as in the above-described embodiment, if a flag for canceling the contract on the center side is set in the terminal contract information stored in the terminal storage unit 120 of the in-vehicle information terminal device 100, the center is deleted each time the user information is deleted. The user deletion process can be performed without communicating with the apparatus 200. Further, after the information deletion guidance and the center cancellation processing flag are updated, the communication with the in-vehicle information terminal device 100 from the center device 200 may be disconnected.

  When the information deletion guide in the in-vehicle information terminal device 100 is received, the user deletes the information in the in-vehicle information terminal device 100 (step s409), and ends this processing.

  When all the user information is deleted by the in-vehicle information terminal device 100 by the above processing, if the contract information remains on the center device 200 side without being consciously connected to the center device 200, Since the contract information remaining on the center device 200 side is deleted by connecting to the center device 200, the contract information on the in-vehicle information terminal device 100 side is deleted, and only the contract information on the center device 200 side is not left. The contract information on the center side and the terminal side can always be matched, and problems due to contract information inconsistency can be avoided.
