To provide an on-vehicle relay device that can efficiently relay information related to maintenance processes for an on-vehicle ECU connected to the on-vehicle relay device.SOLUTION: A plurality of communication units of an on-vehicle relay device include a remote communication unit to which an external communication device for communicating with an external server is connected and a local communication unit to which a diagnostic device is connected. A control unit of the on-vehicle relay device performs lower layer-side control that relays on the basis of a lower-side layer protocol in communication and upper layer-side control that relays on the basis of an upper-side layer protocol rather than the lower-side layer protocol, and when information related to a plurality of maintenance processes for any on-vehicle ECU among a plurality of on-vehicle ECUs is input via the local communication unit and the remote communication unit, performs an arbitration process for conflicts by the plurality of maintenance processes in the upper layer-side control.SELECTED DRAWING: Figure 1

    【課題】自装置に接続される車載ECUに対する保守処理に関する情報の中継を効率的に実施することができる車載中継装置を提供する。【解決手段】車載中継装置の複数の通信部は、外部サーバと通信するための車外通信装置が接続されるリモート通信部と、ダイアグ装置が接続されるローカル通信部とを含み、車載中継装置の制御部は、通信における下位側の階層プロトコルに基づき中継する下位層側制御と、下位側の階層プロトコルよりも、上位側の階層プロトコルに基づき中継する上位層側制御とを行い、ローカル通信部及びリモート通信部を介して、複数の車載ECUのうちのいずれかの車載ECUに対する複数の保守処理に関する情報が入力された場合、上位層側制御にて複数の保守処理による競合に対する調停処理を行う。【選択図】図1
