ABSTRACT:
A control center transmits failure information transmission request information to a vehicle. The vehicle receives the failure information transmission request information transmitted from the control center. A navigation ECU and a gateway ECU obtain failure information from each ECU in cooperation with each other. At this time, the gateway ECU determines whether a data volume of the failure information is larger than a predetermined information volume. When it is determined that the data volume of the failure information is larger than the predetermined information volume, the gateway ECU divides the failure information into plural pieces, and outputs each piece of information. Also, the ECU does not output the failure information, which is output to a network built in the vehicle, to the navigation ECU, while a failure information obtaining device is connected. Meanwhile, the control center does not receive the failure information while the failure information obtaining device is connected.
