Abstract
An in-vehicle network system includes a relay device connecting communication lines to each other and nodes connected to the communication lines. Each of the nodes is configured to enter a wake-up state when the node in the sleep state receives a wake-up signal through the communication line. At least one of the nodes as a requesting node is configured to transmit the wake-up signal. Activation target data is set for each of the nodes. The activation target data for one node indicates at least one other node that is required to activate together with the one node. The relay device obtains the activation target data for the requesting node when receiving the wake-up signals from the requesting node, synthesize the activation target data to generate activation request data, select a target node in accordance with the activation request data, and transmit the wake-up signal to the target node.
