PROBLEM TO BE SOLVED: To provide a gateway, on-vehicle communication system, communication control method, and communication control program, capable of implementing stabler operation of a gateway for relaying information from an external device in an on-vehicle network.SOLUTION: A gateway, a gateway mounted on a vehicle, comprises a communication unit capable of performing communication, via another gateway capable of performing communication with an external device outside the vehicle, with the external device. The other gateway includes: a switch unit for performing relay processing for relaying communication data; and a processing unit for controlling the relay processing of the switch unit. The communication unit can relay the communication data received from the switch unit to a device inside the vehicle. The gateway further comprises a control unit that determines abnormality of the processing unit and controls the relay processing of the switch unit when it is determined that the abnormality has occurred.SELECTED DRAWING: Figure 3

    【課題】車載ネットワークにおいて、外部装置からの情報を中継するゲートウェイのより安定化した動作を実現することが可能なゲートウェイ、車載通信システム、通信制御方法および通信制御プログラムを提供する。【解決手段】ゲートウェイは、車両に搭載されるゲートウェイであって、前記車両の外部における外部装置と通信可能な他のゲートウェイを介して前記外部装置と通信可能な通信部を備え、前記他のゲートウェイは、通信データを中継する中継処理を行うスイッチ部と、前記スイッチ部の前記中継処理を制御する処理部とを含み、前記通信部は、前記スイッチ部から受けた通信データを前記車両の内部における装置へ中継可能であり、前記ゲートウェイは、さらに、前記処理部の異常を判定し、前記異常が発生したと判断した場合、前記スイッチ部の前記中継処理を制御する制御部を備える。【選択図】図3
