Abstract
A plurality of communication units of an on-board relay device include a remote communication unit to which a communication device outside a vehicle for communicating with an external server is connected, and a local communication unit to which a diagnostic device is connected, and a control unit of the on-board relay device performs lower layer side control for relay based on a lower side layered protocol in communication, and upper layer side control for relay based on an upper side layered protocol rather than the lower side layered protocol, and performs adjustment processing with respect to a conflict of a plurality of maintenance processings by the upper layer side control when information relevant to the plurality of maintenance processings with respect to any one on-board ECU of a plurality of on-board ECUs is input through the local communication unit and the remote communication unit.
