The in-vehicle relay device is provided with a control unit that selectively executes the control program or the update processing program stored in the storage unit, and when the control unit executes the control program, the control unit refers to network configuration information stored in the storage unit, specifies a first communication unit to which any one of the in-vehicle ECUs to be relay destinations is connected, and transmits the specified first communication unit to the in-vehicle ECUs to be relay destinations. When executing the update processing program, the control unit refers to the network configuration information stored in the storage unit and specifies a second communication unit for communicating with an external device that performs a process relating to the update of the control program. And prohibits communication by the communication unit other than the second communication unit for communicating with the external device.
车载中继装置具备选择性地执行存储于存储部的所述控制程序或所述更新处理程序的控制部,所述控制部在执行所述控制程序时,参照存储于所述存储部的网络构成信息,确定将成为中继目的地的任一个车载ECU连接的第一通信部,所述控制部在执行所述更新处理程序时,参照存储于所述存储部的网络构成信息,确定用于与进行与所述控制程序的更新有关的处理的外部装置进行通信的第二通信部,禁止由该确定的用于与外部装置进行通信的第二通信部以外的通信部进行的通信。
