Abstract:
1. A vehicle gateway device to be connected with a bus line (BL), on which communication data flow, comprising: a relay function unit connected to a bus line (BL) of a vehicle network, for relaying communication data if communication data flowing on the bus line (BL) is relay data, the relay data being a command to control at least one device of a vehicle, the relay function unit constructed by an application specific integrated circuit, and a network management function unit connected to the relay function unit, for performing a network management process in accordance with network management data if communication data flowing on the bus line (BL) is network management data, the network management data transmitted for the implementation of a network management function of at least one node of the vehicle network and is outputted from the relay function unit, the network management function unit constructed by a microcomputer, the application specific integrated circuit and the microcomputer being disposed on a single device, wherein: the relay function unit includes a first transmitting/receiving section connected to the bus line (BL) for receiving communication data flowing on the bus line (BL) and transmitting the communication data to the bus line (BL), a judging section for judging whether the communication data received by the first transmitting/receiving section is the relay data or the network management data, and at least one queue for storing the relay data and the network management data, wherein the judging section of the relay function unit outputs the communication data judged to be the relay data to the queue of the relay function unit while outputting the communication data judged to be the network management data to the network management function unit, and the network management function unit performs the network management process in accordance with the network management data outputted from the judging section of the relay function unit.
