Abstract: An on-board control device relays data communication between a vehicle module and a vehicle ECU which generates a signal for commanding a driving mode of a vehicle. The on-board control device includes a first interface via which communication with the vehicle ECU is performed, and a second interface via which communication with the vehicle modules is performed. The first interface relies on specifications for communication with the vehicle ECU, and the second interface does not rely on the specifications for communication with the vehicle ECU.
