摘要：The vehicle includes electronic control units, and performs an authentication process to judge the validity of an external device outside the vehicle, e.g. a maintenance device, which tries accessing the electronic control unit. Based on the result of the judgment, the vehicle decides a range in which the maintenance device can access the electronic control unit. In the authentication, e.g. both the maintenance device and the vehicle use authentication microcomputers respectively. According to the invention, an external device outside the vehicle can be inhibited from making an unwanted access to the electronic control unit of the vehicle.
