An in-vehicle network system includes a control unit, a plurality of gateway devices, and a plurality of sensors that collect ambient vehicle information. Each sensor communicates with the control unit via at least one gateway device. The control unit includes a mode management unit that determines an operation mode in a plurality of operation modes associated with the sensor, and a sleep instruction control unit that specifies a gateway device, which is the gateway device in which the connected sensor does not operate, and does not need to relay a sensor, based on the operation mode, and transitions the gateway device having no need to relay the sensor to a low power state in which a processing capacity is lowered. The gateway device is connected to the plurality of sensors which do not operate in any one of the same operation modes without passing through the other gateway devices.
