[System operation]
In such a car navigation system, it is possible to perform long-distance communication using the contractor information of the mobile phone with the car navigation device. The flowcharts of FIGS. 3 and 4 show the flow of operations on the car navigation device side when performing this long-distance communication.

  First, the non-contact IC unit 32 of the car navigation device is provided on a holder on which the mobile phone can be placed. When a user performs a long-distance communication with a car navigation device, the user places a mobile phone on the holder. When the user places a mobile phone on the holder, the non-contact IC unit 32 provided on the holder. And the non-contact IC unit 8 provided in the mobile phone is held at a distance that allows communication, and communication between the non-contact IC units 8 and 32 is started. The flowchart of FIG. 3 starts when the control unit 28 on the car navigation device side detects that the communication between the non-contact IC units 8 and 32 is started.

  Next, in step S1, the control unit 28 on the car navigation device side communicates with the control unit 9 on the mobile phone side via the non-contact IC units 8 and 32, and the display unit 6 on the mobile phone side, for example, Controls the display of a message prompting the user to enter a password such as “Please enter the password”.

  The user operates the operation unit 5 of the mobile phone to input a password, and the control unit 9 on the mobile phone side inputs the input password into the car navigation device via the non-contact IC units 8 and 32. In step S2, the control unit 28 on the car navigation device side determines whether or not the code number transmitted from the control unit 9 on the mobile phone side has been received. It is determined whether or not a password has been input, and the process proceeds to step S3 at the timing when the password is received from the control unit 9 on the mobile phone side.

  In the memory 27 on the car navigation device side, a password entered in advance by the user is stored, and when the control unit 28 on the car navigation device side receives the password from the control unit 9 on the mobile phone side, a step is performed. In S3, the received personal identification number is collated with the personal identification number stored in the memory 27 on the car navigation device side. Then, in step S4, the control unit 28 on the car navigation device side determines whether or not the two personal identification numbers match to determine whether the user authentication is successful, and if the user can be authenticated, the process is performed. The process proceeds to step S5, and if the user cannot be authenticated, the process proceeds to step S12.

  In step S12, since the user could not be authenticated, the control unit 28 on the car navigation device side communicates with the control unit 9 on the mobile phone side via the non-contact IC units 8 and 32, and the display unit on the mobile phone side 6 displays, for example, an authentication error message such as “authentication failed”, and the processing shown in the flowcharts of FIGS. 3 and 4 is terminated.

  In contrast, when the process proceeds to step S5 because the user has been authenticated, the control unit 28 on the car navigation device side communicates with the control unit 9 on the mobile phone side via the non-contact IC units 8 and 32. And request transmission of contractor information. When receiving the transmission request, the control unit 9 on the mobile phone side reads the contractor information stored in the memory 7 on the mobile phone side, and reads the contractor information via the non-contact IC units 8 and 32. To the control unit 28. The control unit 28 on the car navigation device side stores and controls the received contractor information in the memory 27 on the car navigation device side. Thus, the contractor information held on the mobile phone side is copied on the car navigation device side.

  Next, in step S6, the control unit 28 on the car navigation device side communicates with the control unit 9 on the mobile phone side via the non-contact IC units 8 and 32, so that the control unit 9 on the mobile phone side is communicated. A communication cutoff request is made to When this communication cutoff request is made, the control unit 9 on the mobile phone side controls to stop the communication operation performed between the mobile phone and the communication carrier via the antenna 1 and the communication circuit 2 shown in FIG. To do. Thereby, it is possible to prevent inconvenience that long distance communication is simultaneously performed using the same contractor information in the mobile phone and the car navigation device.

  Next, when the control unit 28 on the car navigation device side ends the communication stop control process shown in step S6 of the flowchart of FIG. 3, the process proceeds to step S7 of the flowchart of FIG.

  In this step S7, the control unit 28 on the car navigation device side controls the long-range communication module 31 on the car navigation device side, and uses the contractor information copied to the memory 27, and the communication business corresponding to the contractor information. Long-distance wireless communication is performed via a wireless communication network provided by a person.

  By this long-distance wireless communication, for example, the car navigation device is connected to a predetermined website, and the latest map information, store information around the current position of the car, etc. are downloaded to the HDD 24 of the car navigation device, and the user's It will be used.

  Thus, in the car navigation system of this embodiment, long-distance wireless communication can be performed on the car navigation device side using the contractor information held on the mobile phone side. For this reason, it is possible to eliminate the need for a new contract with a communication carrier, which is necessary when wireless communication is performed by the car navigation device.

  Next, as described above, the non-contact IC unit 32 of the car navigation device is provided in the holder on which the mobile phone can be placed, and the non-contact IC unit 32 of the car navigation device and the non-contact IC of the mobile phone. Communication with the unit 8 is possible with the mobile phone placed on the holder.

  When the mobile phone is placed on the holder and communication is started between the non-contact IC units 8 and 32, the control unit 28 on the car navigation device side receives the mobile phone side via the non-contact IC units 8 and 32. The communication confirmation signal is transmitted to the control unit 9 continuously or intermittently at predetermined intervals. Each time the control unit 9 on the mobile phone side receives the communication confirmation signal, the control unit 9 transmits a reply signal as a response to the communication confirmation signal to the control unit 28 on the car navigation device side. Therefore, the control unit 28 on the car navigation device side transmits the communication confirmation signal to the control unit 9 on the mobile phone side, and if the reply signal is not returned from the control unit 9 on the mobile phone side, This indicates that communication between the car navigation device and the mobile phone has been cut off. That is, the mobile phone is separated from the car navigation device to the extent that communication cannot be performed between the non-contact IC units 8 and 32. This means that the mobile phone has been removed from the holder.

  In step S8, the control unit 28 on the car navigation device side determines whether or not the mobile phone has been removed from the holder by determining the presence or absence of the return signal from the control unit 9 on the mobile phone side. The process proceeds to step S9 when it is determined that the mobile phone has been removed from the holder.

  In step S9, since the cellular phone is removed from the holder, the control unit 28 on the car navigation device side deletes the contractor information copied to the memory 27 on the car navigation device side.

  Thereby, despite the cellular phone being removed from the car navigation device, the contractor information remains stored on the car navigation device side, and the inconvenience that this contractor information is illegally used is prevented. Can do.

  Next, in step S10, the control unit 28 on the car navigation device side determines whether or not the long-distance communication module 31 is communicating even though the mobile phone has been removed from the holder. If the long-distance communication module 31 is not communicating, the processing shown in the flowcharts of FIG. 3 and FIG. 4 is terminated as it is. If the long-distance communication module 31 is communicating, the communication is performed in step S11. The communication of the telecommunications module 31 that is in the middle is stopped and the processing shown in the flowcharts of FIGS. 3 and 4 ends.

  Thus, when the mobile phone is removed from the holder, the communication using the contractor information on the car navigation device side is controlled by stopping the communication of the long-distance communication module 31 on the car navigation device side. It can be limited only when the device and the car navigation device are located within a predetermined distance or less, using the contractor information of the mobile terminal device on the car navigation device side completely separate from the mobile terminal device The inconvenience of performing communication can be prevented.
