FIG. 2 is a flowchart showing an activation program 41 that is executed by the security control means 24 and activates the car navigation device 10. Hereinafter, the procedure by which the security control unit 24 activates the car navigation device 10 will be described with reference to FIG.

  First, a user who uses the car navigation device 10 installed in a car (not shown) carries the mobile phone 30 storing his / her authentication code and gets on the car. When the user turns on the main power supply of the car navigation apparatus 10, the start program 41 starts.

(Step 1) First, the security control unit 24 causes the short-range wireless communication unit 21 to search for the mobile phone 30. Note that the procedure, method, and the like for searching for the mobile phone 30 by the short-range wireless communication means 21 are defined in the Bluetooth standard, and thus description thereof is omitted.

(Step 2) If the short-range wireless communication means 21 finds the mobile phone 30 in the radio wave reachable range, the process proceeds to step 3, and if the mobile phone 30 is not found in the radio wave reachable range, the activation program 41 ends.

(Step 3) When the mobile phone 30 is found, the short-range wireless communication means 21 requests the short-range wireless communication means 31 of the mobile phone 30 to transmit an authentication code. Upon receiving the request for transmitting the authentication code, the short-range wireless communication means 31 reads out the authentication code of the exclusive user of the mobile phone 30 from the exclusive-person authentication code storage means 32 and transmits it to the short-range wireless communication means 21.

(Step 4) When the short-range wireless communication means 21 receives the authentication code transmitted from the short-range wireless communication means 31 of the mobile phone 30, the authentication code determination means 23 uses the authentication code transmitted from the mobile phone 30 and the authorized user. The verification code of the authorized user read from the authentication code storage means 22 is collated.

(Step 5) If the authentication code transmitted from the mobile phone 30 matches the authentication code of the authorized user, the authentication code determination means 23 notifies the security control means 24 to that effect and proceeds to Step 6. If they do not match, the startup program 41 ends.

(Step 6) The car navigation apparatus 10 is activated. The authentication code transmitted from the mobile phone 30 and matched with the authentication code of the authorized user read from the authorized user authentication code storage means 22, that is, the authentication code used to activate the car navigation device 10 is activated code. I will call it.

(Step 7) The reading and writing of the personal information corresponding to the activation code from the personal information storage means 11 is permitted.

[Permission to access personal information of other users]
When the car navigation device 10 is activated, access to the personal information of the authorized user recognized at the time of activation is permitted. However, if there are other authorized users in the vehicle, access to the personal information of other authorized users is also permitted. Is done.

  FIG. 3 is a flowchart showing an access permission program 42 which is executed by the security control means 24 and permits access to personal information of other users. Hereinafter, a procedure in which the security control unit 24 permits access to the personal information of other users will be described with reference to FIG.

  Two users A and B carry a mobile phone 30 storing their respective authentication codes in a car (not shown) provided with the car navigation device 10, and turn on the main power of the car navigation device 10. Consider a case where the security unit 20 first recognizes the mobile phone 30 of the user A and activates the car navigation device 10. At this time, the car navigation apparatus 10 is activated using the authentication code of the user A as an activation code.

  When the car navigation device 10 is activated, the security control unit 24 activates the access permission program 42 and thereafter repeats the activation of the access permission program 42 every predetermined time. This is because after the car navigation device 10 is activated, another user may get on after a lapse of time.

(Step 11) The security control unit 24 causes the short-range wireless communication unit 21 to search for the mobile phone 30.

(Step 12) If the short-range wireless communication means 21 finds the mobile phone 30 in the radio wave reachable range, the process proceeds to step 13, and if the mobile phone 30 is not found in the radio wave reachable range, the access permission program 42 ends.

(Step 13) An authentication code is sent from the short-range wireless communication means 21 to the short-range wireless communication means 31 of all the found mobile phones 30 (in this case, two mobile phones 30 of users A and B are found). Request to send The short-range wireless communication means 31 that has received the request for transmitting the authentication code reads the authentication code of the exclusive person of the mobile phone 30 from the exclusive-person authentication code storage means 32 and transmits it to the short-range wireless communication means 21.

(Step 14) When the short-range wireless communication means 21 receives the authentication code transmitted from the short-range wireless communication means 31 of the mobile phone 30, the authentication code determination means 23 receives the authentication code received by the short-range wireless communication means 21. And the authentication code of the authorized user read from the authorized user authentication code storage means 22 are collated.

(Step 15) If the authentication code received by the short-range wireless communication means 21 matches the authentication code of the authorized user, the authentication code determination means 23 notifies the security control means 24 to that effect and proceeds to Step 16. If all the authentication codes do not match, the access permission program 42 ends. The authentication code received by the short-range wireless communication unit 21 in step 14 and confirmed by the authentication code determination unit 23 in step 15 to match the authentication code of the authorized user is referred to as an additional code.

(Step 16) The additional code is an activation code or other additional code (if the access control program 42 is executed more than once, an additional code may be generated during the execution of the previous access permission program 42) If it matches, the access permission program 42 ends. If they do not match any of them, the process proceeds to step 17.

(Step 17) The reading and writing of the personal information corresponding to the additional code newly recognized in Step 16 (in this case, the authentication code of User B) from the personal information storage unit 11 is permitted.

[Select personal information]
As described above, when the access permission program 42 is executed, it becomes possible to access (read and write) the personal information of the user B in addition to the personal information of the user A. However, since the amount of information that can be displayed on the display device (not shown) of the car navigation device 10 is limited, it is difficult to display the personal information of the users A and B at the same time. Therefore, the security unit 20 allows the user to select and access any one of the personal information of a plurality of users permitted to access.

  FIG. 4 is a flowchart showing a personal information selection program 43 that is executed by the security control means 24 and allows the user to select one of the user's personal information from among the plurality of users' personal information. Hereinafter, with reference to FIG. 4, a procedure for causing the user to select personal information of any one of a plurality of users' personal information will be described.

  The personal information selection program 43 starts after the security control device 20 permits access to the personal information corresponding to the additional code, that is, after step 17 of the access permission program 42 is executed and terminated.

(Step 21) A message as shown in FIG. 5 is displayed on the display device (not shown) of the car navigation device 10 to access the personal information of the newly recognized authorized user to the users A and B. Ask if it is necessary. Then, the users A and B input an answer to this question to the car navigation device 10.

(Step 22) The car navigation device 10 switches the display on the display device of the car navigation device 10 according to the user's answer. That is, if the answer input by the user is “Yes”, the personal information of the newly recognized user B is displayed, and if “No”, the display of the personal information of the user A that has been conventionally selected is continued.

[Automatic stop of car navigation system]
Further, the security control device 20 can automatically stop the car navigation device 10 when there is no authorized user from the side of the car navigation device 10. The car navigation apparatus 10 includes a selection switch (not shown) that selects whether to enable or disable the automatic stop. This selection switch can be operated by all persons in the vehicle.

  FIG. 6 is a flowchart showing an automatic stop program 44 that is executed by the security control means 24 and automatically stops the car navigation apparatus 10. Hereinafter, a procedure in which the security control unit 24 automatically stops the car navigation apparatus 10 will be described with reference to FIG. The automatic stop program 44 is repeatedly executed with a predetermined time interval during the operation of the car navigation apparatus 10.

(Step 31) The security control means 24 causes the short-range wireless communication means 21 to search for the mobile phone 30.

(Step 32) If the short-range wireless communication means 21 finds the mobile phone 30 within the radio wave reachable range, the process proceeds to step 33. If the mobile phone 30 is not found within the radio wave reachable range, the process proceeds to step 37.

(Step 33) The short-range wireless communication means 21 requests the short-range wireless communication means 31 of all the found mobile phones 30 to transmit an authentication code. The short-range wireless communication means 31 that has received the request for transmitting the authentication code reads the authentication code of the exclusive person of the mobile phone 30 from the exclusive-person authentication code storage means 32 and transmits it to the short-range wireless communication means 21.

(Step 34) When the short-range wireless communication means 21 receives the authentication code transmitted from the short-range wireless communication means 31 of the mobile phone 30, the authentication code determination means 23 receives the authentication code and the regular user authentication code storage means 22 The authentication code of the legitimate user read from is verified.

(Step 35) When any of the authentication codes transmitted from all the mobile phones 30 matches the authentication code of the authorized user, the automatic stop program 44 ends. If all the authentication codes do not match, the process proceeds to step 36.

(Step 36) The security control means 24 determines whether the selection switch is valid or invalid. If the selection switch is valid, the process proceeds to step 37, and if it is invalid, the automatic termination program 44 is terminated.

  With this configuration, if the selection switch is disabled, the main power supply of the car navigation device 10 is not shut off even if the authorized user leaves the car. As a result, even if the authorized user temporarily leaves the car, a person other than the authorized user who remains in the car can perform navigation operations such as changing the destination or re-searching the travel route with the car navigation device 10, And watching TV.

(Step 37) The security control means 24 instructs the car navigation device 10 to execute a predetermined stop sequence, and after the sequence ends, the main power supply of the car navigation device 10 and the security unit 20 is shut off.

  Alternatively, prior to the execution of step 37, the message shown in FIG. 7 is displayed on the display device (not shown) of the car navigation device 10 to determine whether or not to cut off the main power supply to a person other than the authorized user remaining in the vehicle. May be selected. When “Yes” is selected, the main power supply of the car navigation device 10 and the security unit 20 is shut off. On the other hand, if “No” is selected, the main power supply of the car navigation device 10 is not shut off. As described above, the car navigation device 10 can perform navigation operations such as changing the destination and re-searching the driving route, You can watch music and TV. When neither “Yes” nor “No” is selected within a predetermined time (for example, within 3 minutes), the main power supply of the car navigation device 10 and the security unit 20 may be shut off by a timer.

  Alternatively, in step 37, instead of turning off the main power supply of the car navigation device 10, some operations of the car navigation device 10 may be restricted. For example, when the authorized user temporarily leaves the car, the audio operation can be performed but the navigation operation cannot be performed.

  As described above, the security unit 20 automatically searches the mobile phone 30 around the car navigation device 10 and uses the authentication code transmitted by the mobile phone device 30 as the authentication code of the authorized user of the car navigation device 10. Therefore, manual entry of the authentication code by the user is not required.

  Further, when a plurality of authorized users are on the side of the car navigation device 10, it can be automatically recognized and access to the personal information of the recognized authorized users can be permitted.

  Further, when there is no regular user on the side of the car navigation device 10, it can be automatically recognized and the car navigation device 10 can be automatically stopped.
