Thereby, the cost of the driving environment setting system 1 can be reduced.

  In the driving environment setting system 1, the in-vehicle device 20 receives driving environment information from the portable device 10 in advance before the user who performs driving gets on the host vehicle. For this reason, compared with the case where the in-vehicle device 20 receives the driving environment information from the portable device 10 placed in the vicinity of the driver's seat, etc., the in-vehicle device 20 performs wireless communication with the portable device 10 after getting on the host vehicle. The required time can be reduced, and the driving environment according to this user can be arranged sooner after the driving user gets on the own vehicle. Therefore, the usability of the driving environment setting system 1 can be improved.

  More specifically, the in-vehicle device 20 and the mobile device 10 perform wireless communication by Bluetooth (registered trademark). When the in-vehicle device 20 receives the driving environment information from the portable device 10, it is necessary to perform mutual authentication or the like between the in-vehicle device 20 and the portable device 10. It is predicted that an average of about 3 s will be required before receiving. However, there is no problem even if it takes about 3 seconds for the in-vehicle device 20 to receive the driving environment information from the portable device 10 before the user is seated on the seat of the host vehicle. In the driving environment setting system 1, a Bluetooth address used for specifying each terminal in Bluetooth (registered trademark) is used as identification information of the mobile device 10. For this reason, the time required until the in-vehicle device 20 receives the identification information (Bluetooth address) from the portable device 10 is predicted to be about 1 s on average. Therefore, after the user is seated in the driver's seat, the in-vehicle device 20 receives only the identification information (Bluetooth address) from the portable device 10, thereby shortening the time that the driving user waits until the driving environment of the host vehicle is prepared. The usability of the driving environment setting system 1 can be improved.

  The in-vehicle device 20 determines whether or not a response has been received from the mobile device 10 existing in the second area 210 based on the electric field strength of the radio wave received from the mobile device 10 (S325). For this reason, after the user is seated in the driver's seat, the in-vehicle device 20 can accurately identify the Bluetooth address received in wireless communication with the mobile device 10 possessed by the user who is driving.
