The invention relates to a gateway apparatus, an in-vehicle network system, and a firmware updating method. A gateway (300), which is connected to a bus for communication with a plurality of ECUs (100a-100d) mounted on a vehicle, is provided with: a reception unit that receives firmware update information including update firmware to which one of the plurality of ECUs (100a-100d) is to be applied, from a server (500) that is an external device outside the vehicle; and a control unit that determines whether or not the ECU satisfies a predetermined condition on the basis of the information of the ECU to which the firmware for updating is to be applied, and performs control so that the ECU executes a predetermined process associated with the update of the firmware when the predetermined condition is satisfied, and so that the ECU executes a predetermined process other than the ECU when the predetermined condition is not satisfied.
本公开涉及网关装置、车载网络系统以及固件更新方法。连接于供车辆所搭载的多个ECU(100a~100d)进行通信所使用的总线的网关(300)具备:接收部,其从作为车辆外的外部装置的服务器(500)接收固件更新信息,所述固件更新信息包括以多个ECU(100a~100d)中的一个ECU为适用对象的更新用固件;以及控制部,其基于作为更新用固件的适用对象的ECU的信息,判定该ECU是否满足预定条件,并进行控制以使得:在满足预定条件的情况下,使该ECU执行与固件的更新关联的预定处理,在不满足预定条件的情况下,在该ECU以外执行预定处理。
