(Embodiment)
(Functional configuration of in-vehicle equipment)
A functional configuration of the in-vehicle device 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram illustrating an example of a functional configuration of the in-vehicle device 100 according to the present embodiment. This in-vehicle device 100 can transmit / receive information to / from an external information management server.

  In FIG. 1, an in-vehicle device 100 includes an authentication unit 110, a control unit 120, a transmission unit 130, a reception unit 140, a setting information storage unit 150, an output unit 160, a detection unit 170, and an authentication information storage unit. 180 and a time limit setting unit 190. The control unit 120 also includes a function setting unit 121, a first erasing unit 122, a determination unit 123, a second erasing unit 124, a third erasing unit 125, and a fourth erasing unit 126.

  The authentication unit 110 authenticates the user when the in-vehicle device 100 is activated. At the time of start-up, the accessory power is turned on or there is an input to turn on the power button of the in-vehicle device 100. The authentication unit 110 authenticates the user at the timing when the in-vehicle device 100 is activated under the control of the control unit 120. The authentication unit 110 registers a user ID and a corresponding password as information for user authentication in advance, and compares the information input by the user with the registered authentication information. Perform authentication.

  Note that the information corresponding to the user ID is not limited to a password, but may be a card, a fingerprint, a voice, a face image, or the like. When authentication is performed by the information management server, the authentication unit 110 may only accept input of authentication information (for example, a user ID and a password).

  The transmission unit 130 transmits information on the authentication result by the authentication unit 110 to the information management server. The information of the authentication result may be information that can identify who the user is in the information management server, and specifically, is a user ID. When authentication is performed by the information management server, the transmission unit 130 may transmit authentication information (for example, a user ID and a password) as authentication result information.

  The receiving unit 140 receives user setting information corresponding to the authentication result from the information management server. The user setting information is information set for each user in order to set various functions. The user setting information is set in advance in association with the user ID in the information management server.

  The setting information storage unit 150 stores user setting information received by the receiving unit 140. Specifically, the setting information storage unit 150 includes, for example, a RAM or a magnetic disk.

  The function setting unit 121 of the control unit 120 sets various functions that can be set differently for each user based on the user setting information. By setting various functions, for example, in a navigation device, a display format, a search format (search condition), a guidance format, and the like are switched for each user. Moreover, in an audio apparatus, music selection, a music tone, etc. switch for every user. Various information is output from the output unit 160 such as a display or a speaker based on the setting by the function setting unit 121.

  In the present embodiment, the detection unit 170 and the first erasure unit 122 are arbitrary components. The detection unit 170 detects the end of use of the in-vehicle device 100. Specifically, the in-use state of the in-vehicle device 100 includes a state in which the power source of the in-vehicle device 100 is turned off, a state in which a side brake is applied, a state in which the gear is positioned in the parking gear, and a state in which the vehicle is stopped in the parking lot Etc. The first erasure unit 122 erases the user setting information stored in the setting information storage unit 150 when the end of use of the in-vehicle device 100 is detected.

  In the present embodiment, the authentication information storage unit 180 and the determination unit 123 are arbitrary components. The authentication information storage unit 180 stores authentication result information. When the authentication unit 110 performs user authentication, the determination unit 123 determines whether the previous authentication result stored in the authentication information storage unit 180 is the same as the current authentication result.

  In this case, when the determination unit 123 determines that the previous authentication result and the current authentication result are the same, the transmission unit 130 does not transmit information on the current authentication result. The function setting unit 121 sets the various functions based on user setting information corresponding to the previous authentication result stored in the setting information storage unit 150.

  In the present embodiment, the second erasing unit 124 is an optional component. The second erasure unit 124 erases the user setting information corresponding to the previous authentication result stored in the setting information storage unit 150 when it is determined that the previous authentication result and the current authentication result are not the same. .

  In the present embodiment, the time limit setting unit 190 and the third erasing unit 125 are optional components. The time limit setting unit 190 sets an expiration date for the user setting information stored in the setting information storage unit 150. The third erasure unit 125 erases the user setting information when the current date has passed the expiration date. The expiration date can be set in units of hours, days, weeks, months, etc.

  In the present embodiment, the fourth erasing unit 126 is an arbitrary component. The fourth erasure unit 126 erases the user setting information stored in the setting information storage unit 150 when the authentication unit 110 cannot authenticate the user or when the reception unit 140 cannot receive the user setting information. To do. In this case, the function setting unit 121 sets various functions to initial values.

  In the present embodiment, the user setting information managed by the information management server may be set from a terminal other than the in-vehicle device 100. The other terminals are specifically PC terminals installed at home or the like, mobile phone terminals owned by users, and the like.

(In-vehicle device function setting process)
Next, a function setting process procedure of the in-vehicle device 100 will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of a function setting process procedure of the in-vehicle device 100 according to the present embodiment.

  In the flowchart of FIG. 2, the in-vehicle device 100 is in a standby state until it is activated (step S201: No loop), and when activated (step S201: Yes), the authentication unit 110 performs user authentication processing (step S202). . Then, it is determined whether or not the authentication is successful (step S203). When the authentication is successful (step S203: Yes), the transmission unit 130 transmits the authentication result to the information management server (step S204).

  Thereafter, the receiving unit 140 receives user setting information corresponding to the authentication result from the information management server (step S205), and stores the user setting information received by the setting information storage unit 150 (step S206). Then, the function setting unit 121 sets a function based on the user setting information (step S207), and the series of processing ends. On the other hand, if the authentication fails in step S203 (step S203: No), the series of processing ends.

  When the authentication process is performed by the information management server, the authentication information is received in step S202 described above, and the received authentication information is transmitted as an authentication result without performing the process of step S203 (step S204). That's fine. Then, when authentication is successful in the information management server, user setting information may be received (step S205).

  As described above, the in-vehicle device 100 according to the present embodiment receives the user setting information of the user who is authenticated at the time of activation from the information management server, and sets the function based on the user setting information. Therefore, the function can be set in the in-vehicle device 100 without requiring a complicated operation input.

  Further, if the user setting information stored in the setting information storage unit 150 is deleted by the first deletion unit 122 when the end of use of the in-vehicle device 100 is detected, the user who uses this time uses the previous use. It is possible to protect the privacy of the user used last time without feeling troublesome due to the setting of the user's function remaining.

  Further, when the determination unit 123 determines that the previous authentication result and the current authentication result are the same, the previous authentication result stored in the setting information storage unit 150 is not transmitted without transmitting the information on the current authentication result. If various functions are set based on the user setting information corresponding to the authentication result, the previous settings can be taken over and the functions can be set quickly.

  When the determination unit 123 determines that the previous authentication result and the current authentication result are not the same, the user setting information corresponding to the previous authentication result stored in the setting information storage unit 150 is second erased. If the deletion is performed by the unit 124, it is possible to protect the privacy of the user used last time without feeling annoyed by the setting of the function of the user used last time remaining for the user used this time.

  Moreover, when the expiration date is set in the expiration date setting unit 190 for the user setting information stored in the setting information storage unit 150 and the current date and time has passed the expiration date, the user setting information is stored in the third deletion unit. If the information is erased by 125, it is possible to reduce the load on the memory and protect the privacy of the user corresponding to the user setting information without storing unnecessary information for a long period of time.

  Further, if the user setting information stored in the setting information storage unit 150 is deleted by the fourth deletion unit 126 when the user cannot be authenticated or the user setting information cannot be received, the initial setting can be performed. It can be set, and the user who is used this time can feel the annoyance caused by the setting of the function of the user used last time, and can protect the privacy of the user used last time. For example, when a non-registered user unrelated to the owner of the vehicle uses, it can be used as an initial setting.

  Further, the user setting information managed by the information management server can be set from a PC terminal, for example, if it can be set from a terminal other than the in-vehicle device 100. Therefore, the setting can be performed when the user has enough time, and the setting can be performed from a user-friendly terminal such as an operation input as compared with the in-vehicle device 100 such as a PC terminal.

  When authentication is performed by the information management server, the authentication unit 110 accepts input of authentication information (for example, a user ID and password), and the transmission unit 130 receives authentication information (for example, a user ID and a password). If the password is transmitted as the authentication result information, it is possible to set the compatible in-vehicle device 100. For example, for the in-vehicle device 100 mounted in another person's vehicle or a rental car. In addition, it is possible to set functions for each user.

  Examples of the present invention will be described below. In this embodiment, an information management system including an information management server and a navigation device will be described. In the following description, an example in which the in-vehicle device according to the present invention is implemented by a navigation device mounted on a vehicle will be described.

(Outline of information management system)
First, the outline of the information management system 300 according to the present embodiment will be described with reference to FIG. FIG. 3 is an explanatory diagram illustrating an overview of the information management system 300 according to the present embodiment.

  In FIG. 3, the information management system 300 includes a navigation device 301 and an information management server 302. The navigation device 301 and the information management server 302 are connected by a network 310.

  The navigation device 301 is mounted on a vehicle, authenticates a user, transmits a user ID input by the user to the information management server 302, and receives user setting information corresponding to the user ID from the information management server 302. Then, various functions are set based on the user setting information.

  The information management server 302 stores the user ID and user setting information in association with each other. The user setting information can be used to make various settings for the navigation device 301 from a PC terminal or a mobile phone terminal in addition to the navigation device 301. The information management server 302 extracts user setting information corresponding to the user ID received from the navigation device 301 and transmits it to the navigation device 301.

(Hardware configuration of navigation device)
The hardware configuration of the navigation device 301 according to the present embodiment will be described with reference to FIG. FIG. 4 is a block diagram illustrating an example of a hardware configuration of the navigation device 301 according to the present embodiment.

  In FIG. 4, the navigation device 301 includes a CPU 401, ROM 402, RAM 403, magnetic disk drive 404, magnetic disk 405, optical disk drive 406, optical disk 407, audio I / F (interface) 408, and microphone 409. A speaker 410, an input device 411, a video I / F 412, a display 413, a camera 414, a communication I / F 415, a GPS unit 416, and various sensors 417. Each component 401 to 417 is connected by a bus 420.

  The CPU 401 governs overall control of the navigation device 301. A rewritable nonvolatile memory such as a ROM 402 or a flash ROM records various programs such as a boot program, a current position calculation program, a route search program, a route guidance program, and a function setting program. The RAM 403 is used as a work area for the CPU 401.

  The current position calculation program, for example, calculates the current position of the vehicle (the current position of the navigation device 301) based on output information from a GPS unit 416 and various sensors 417 described later.

  The route search program searches for an optimal route from the departure point to the destination point using map data recorded on a magnetic disk 405 described later. Here, the optimum route is a shortest (or fastest) route to the destination point or a route that best matches a condition specified by the user. Further, not only the destination point but also a route to a stop point or a rest point may be searched. The searched guidance route is output to the audio I / F 408 and the video I / F 412 via the CPU 401.

  The route guidance program is based on the guidance route information searched by executing the route search program, the current position information of the vehicle calculated by executing the current position calculation program, and the map data read from the magnetic disk 405. Real-time route guidance information is generated. The generated route guidance information is output to the audio I / F 408 and the video I / F 412 via the CPU 401.

  The function setting program is a program that authenticates a user at the time of activation and sets and deletes various functions based on user setting information received from the information management server 302 in response to transmission of a user ID to the information management server 302. Information to be received or transmitted is acquired from the communication I / F 415 or output to the communication I / F 415.

  The magnetic disk drive 404 controls the reading / writing of the data with respect to the magnetic disk 405 according to control of CPU401. The magnetic disk 405 records data written under the control of the magnetic disk drive 404. As the magnetic disk 405, for example, an HD (hard disk) or an FD (flexible disk) can be used.

  The magnetic disk 405 or RAM 403 is registered for each user, and records user ID and password information for authenticating the user. Further, the magnetic disk 405 and the RAM 403 record user setting information transmitted from the information management server 302 and acquired via the communication I / F 415, information on the expiration date of the user setting information, and the like. Further, the magnetic disk 405 and the RAM 403 record the user ID and password of the user used last time.

  The optical disk drive 406 controls the reading / writing of the data with respect to the optical disk 407 according to control of CPU401. The optical disc 407 is a detachable recording medium from which data is read according to the control of the optical disc drive 406. As the optical disc 407, a writable recording medium can be used. In addition to the optical disk 407, the removable recording medium may be an MO, a memory card, or the like.

  The audio I / F 408 is connected to the microphone 409 and the speaker 410. For example, the microphone 409 may be installed near the sun visor of the vehicle, and the number thereof may be one or more. The sound received by the microphone 409 is A / D converted in the sound I / F 408. Note that it is also possible to authenticate a user using audio information input to the microphone 409. The speaker 410 outputs sound.

  Examples of the input device 411 include a remote controller including a plurality of keys for inputting characters, numerical values, various instructions, a keyboard, a mouse, a touch panel, and the like. The input device 411 may be realized by any one of a remote controller, a keyboard, a mouse, and a touch panel, or may be realized by a plurality of forms. The input device 411 is used to input a user ID and password from the user.

  The video I / F 412 is connected to the display 413. Specifically, the video I / F 412 includes, for example, a graphic controller that controls the entire display 413, a buffer memory such as a VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a graphic controller. Based on the output image data, the display 413 is configured by a control IC that controls display.

  The display 413 displays icons, cursors, menus, windows, or various data such as characters and images. As the display 413, for example, a CRT, a TFT liquid crystal display, a plasma display, or the like can be adopted. The display 413 is installed near the dashboard of the vehicle, for example.

  The camera 414 captures the exterior or interior of the vehicle. The information to be photographed may be a moving image or a still image. The user can also be authenticated by recognizing the user's face image taken by the camera 414.

  The communication I / F 415 is connected to a network via wireless and functions as an interface between the navigation device 301 and the CPU 401. The communication I / F 415 is further connected to a communication network such as the Internet via wireless, and also functions as an interface between the communication network and the CPU 401. The communication I / F 415 acquires user setting information transmitted from the information management server 302.

  The GPS unit 416 receives radio waves from GPS satellites and outputs information indicating the current location of the vehicle. The output information of the GPS unit 416 is used when the current position of the vehicle is calculated by the CPU 401 together with output values of various sensors 417 described later. The information indicating the current location is information for specifying one point on the map data, such as latitude / longitude and altitude.

  The various sensors 417 output information such as a vehicle speed sensor, an acceleration sensor, and an angular velocity sensor that can determine the position and behavior of the vehicle. The output values of the various sensors 417 are used for the calculation of the current location of the vehicle by the CPU 401, the measurement of the change in speed and direction, and the like.

  The in-vehicle device 100 shown in FIG. 1 includes an authentication unit 110, a control unit 120, a transmission unit 130, a reception unit 140, a setting information storage unit 150, an output unit 160, a detection unit 170, and authentication information. The storage unit 180 and the time limit setting unit 190 are programs and data recorded in the rewritable nonvolatile memory such as the ROM 402 and the flash ROM in the navigation device 301 shown in FIG. 4, the RAM 403, the magnetic disk 405, and the optical disk 407. The CPU 401 executes a predetermined program and controls each part in the navigation device 301 to realize the function.

  That is, the navigation device 301 of the present embodiment is shown in FIG. 1 by executing a function setting program recorded in a rewritable nonvolatile memory such as a ROM 402 or a flash ROM as a recording medium in the navigation device 301. Functions provided in the in-vehicle device 100 can be executed by the function setting process procedure shown in FIG.

(Example of function setting processing performed by the navigation device)
Next, an example of a function setting process performed by the navigation device 301 according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of a function setting process performed by the navigation device 301 according to the present embodiment.

  In FIG. 5, the navigation device 301 is in a standby state until it is activated, for example, when the accessory power supply is turned on (step S501: No loop), and when activated (step S501: Yes), the user authentication process is performed ( Step S502). The authentication process is performed by determining whether or not the user ID and password input by the user are registered in advance. A display screen when accepting input of a user ID and a password from the user will be described later with reference to FIG.

  Thereafter, it is determined whether or not the authentication is successful (step S503). If the authentication is successful (step S503: Yes), it is determined whether there is user setting information stored in the RAM 403 or the like (step S504). This user setting information is user setting information of the user used last time. If it is determined in step S504 that there is stored user setting information (step S504: Yes), it is determined whether the user setting information is within the expiration date (step S505).

  If it is determined that the user setting information is within the expiration date (step S505: Yes), it is determined whether the current authentication result (user ID and password) is the same as the previous authentication result (step S506). When it is determined that it is not the same as the previous authentication result (step S506: No), the stored user setting information is deleted (step S507). Note that the user setting information is erased by moving from step S506 to step S507 by the function of the second erasure unit 124 shown in FIG.

  Then, the authentication result (user ID) is transmitted to the information management server 302 (step S508). It is also possible to authenticate the information management server 302 by transmitting the user ID and password to the information management server 302. Thereafter, it is determined whether or not the user setting information has been received (step S509).

  In step S509, when the user setting information is received (step S509: Yes), the received user setting information is stored in the RAM 403 or the like (step S510). Then, the function is set based on the stored user setting information (step S511). Specifically, the function settings are settings such as a display format and a guidance format according to the user. Note that the display screen when the function is set in step S511 will be described later with reference to FIG. After that, a standby state is maintained in which the setting of the function is held until use ends (step S517: No loop).

  On the other hand, if it is determined in step S504 that there is no stored user setting information (step S504: No), specifically, if the previously used user setting has been deleted, the process proceeds to step S508. If it is determined in step S505 that the user setting information is not within the expiration date (step S505: No), that is, if the period from the previous use to the current use has passed the expiration date, step S507 is performed. Migrate to

  Here, the erasure of the user setting information by moving from step S505 to step S507 is performed by the function of the third erasure unit 125 shown in FIG. Note that the user setting information in step S507 can be deleted after determining whether or not the user setting information can be received in step S509. In this case, the user setting information is deleted when the user setting information cannot be received. This erasing is performed by the function of the fourth erasing unit 126 shown in FIG.

  If it is determined in step S506 that the current authentication result is the same as the previous authentication result (step S506: Yes), the function is set based on the previous user setting information (step S512), and step S517. Migrate to In step S503, if authentication fails (step S503: No), specifically, if the authentication ID and password are not registered in advance, or if there is no login input as a guest user, If the user button (see FIG. 6) is selected, it is determined whether there is user setting information stored in the RAM 403 or the like (step S513).

  If it is determined that there is stored user setting information (step S513: Yes), the stored user setting information is deleted (step S514), and various functions are set to initial values (step S515). Note that the user setting information is deleted in step S514 by the function of the fourth deletion unit 126 shown in FIG. Then, the function is set based on the user setting information as a guest user (step S516), and the process proceeds to step S517. In step S509, if user setting information cannot be received (step S509: No), the process proceeds to step S515.

  When the use is finished in step S517 (step S517: Yes), specifically, the in-vehicle device 100 is turned off, the side brake is applied around the destination, and the gear is set around the destination. When the vehicle is in the parking gear state or the parking lot, it is determined whether or not the user setting information is set to be deleted (step S518). Note that the determination in step S518 is not limited to the setting in advance, but may be determined by notifying the display 413 whether or not the function setting is to be deleted each time the use is finished, and by input from the user. .

  If it is determined in step S518 that the user setting information is set to be deleted (step S518: Yes), the stored user setting information is deleted (step S519), and the series of processes is terminated. Note that the user setting information is erased in step S519 by the function of the first erasure unit 122 shown in FIG. On the other hand, if it is determined in step S518 that the user setting information is not set to be deleted (step S518: No), the user setting information is kept stored, and the series of processing ends.

(Example of authentication screen displayed when the navigation device is started)
Next, an example of an authentication screen displayed when the navigation device 301 is activated will be described with reference to FIG. FIG. 6 is an explanatory diagram illustrating an example of an authentication screen displayed when the navigation device 301 is activated.

  In FIG. 6, an authentication screen 600 is displayed on the display 413. The authentication screen includes a notification area 601 for prompting input of a user ID and password, a display area 602 for receiving input of the user ID and password, and a guest user button 603 for a user who has not previously registered the user ID and password. It is displayed.

  When the user ID and password are input, authentication processing is performed (see step S502 and step S503 in FIG. 5). On the other hand, when the guest user button 603 is selected, various functions are set to initial values, and functions are set based on user setting information as a guest user (see steps S503, S515, and S516 in FIG. 5). .

(Example of display screen when function setting corresponding to authenticated user is completed)
Next, an example of a display screen when the function setting corresponding to the authenticated user is completed will be described with reference to FIG. FIG. 7 is an explanatory diagram illustrating an example of a display screen when the function setting corresponding to the authenticated user is completed.

  In FIG. 7, a display screen 700 displayed on the display 413 displays a notification area 701 indicating that function setting has been performed in response to the user, and a map screen area 702. This display screen is a screen displayed after step S511 shown in FIG. 5 or after step S512. In the case of a guest user, the notification area 701 is notified of, for example, “Welcome guest user”. After this display screen 700, the display is switched to the normal display, the set function is retained, and the destination can be set, for example.

  As described above, according to the navigation apparatus 301 according to the present embodiment, the user setting information of the user authenticated at the time of activation is received from the information management server, and the function is set based on the user setting information. Thus, the function can be set by the navigation device 301 without requiring complicated operation input.

  Further, since the stored user setting information is erased when the end of use of the navigation device 301 is detected (see step S519 in FIG. 5), the function of the user used last time is used for the user used this time. It is possible to protect the privacy of the user who used the previous time without feeling bothered by the remaining settings.

  Further, when it is determined that the previous authentication result and the current authentication result are the same, the information on the current authentication result is not transmitted, and the user setting information corresponding to the stored previous authentication result is used. Since various functions are set (see step S512 in FIG. 5), the previous settings can be taken over, and the functions can be set quickly.

  Further, when it is determined that the previous authentication result and the current authentication result are not the same, the stored user setting information corresponding to the previous authentication result is deleted (steps S506 and S506 in FIG. 5). In step S507, it is possible to protect the privacy of the user used last time without feeling troublesome due to the setting of the function of the user used last time remaining for the user used this time.

  Further, an expiration date is set for the stored user setting information, and when the current date and time has passed the expiration date, the user setting information is deleted (steps S505 and S507 in FIG. 5). For example, it is possible to reduce the load on the memory and protect the privacy of the user corresponding to the user setting information without storing unnecessary information for a long time.

  In addition, when the user cannot be authenticated or when the user setting information cannot be received, the user setting information stored in the setting information storage unit 150 is deleted by the fourth deletion unit 126 (see FIG. 5 (see step S513 and step S514 of FIG. 5), the initial setting can be made, and the user who uses this time does not feel bothered by the setting of the function of the user used last time. You can protect your privacy. For example, when a non-registered user unrelated to the owner of the vehicle uses, it can be used as an initial setting.

  Further, the user setting information managed by the information management server can be set from a PC terminal, for example, if it can be set from a terminal other than the navigation device 301. Therefore, setting can be performed when the user has enough time, and setting can be performed from a user-friendly terminal such as an operation input compared to the navigation device 301 such as a PC terminal.

  As described above, the in-vehicle device, the function setting method, the function setting program, and the recording medium of the present invention can set functions in the in-vehicle device without requiring complicated operation input.

  The function setting method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
