PROBLEM TO BE SOLVED: To provide an on-vehicle network system capable of beginning relay of communication earlier between node groups performing operation related to the same function, out of multiple nodes for connection with a relay device, when starting the relay device.SOLUTION: An on-vehicle network system includes multiple first nodes related to a prescribed first function in a vehicle, a second node related to a second function different from the first function in the vehicle, and a relay device for relaying mutual communication of the multiple first nodes and the second node, where the relay device begins the relay of mutual communication among the multiple first nodes before the relay of communication between the first and second nodes.SELECTED DRAWING: Figure 3 【課題】中継装置の起動時に、中継装置に接続される複数のノードのうちの同一の機能に関連する動作を行うノード群の間での通信の中継をより早く開始させることが可能な車載ネットワークシステム等を提供する。【解決手段】車両における所定の第１機能に関連する複数の第１ノードと、前記車両における前記第１機能と異なる第２機能に関連する第２ノードと、前記複数の第１ノード及び前記第２ノードの相互間の通信を中継する中継装置と、を含み、前記中継装置は、起動時に、前記第１ノードと前記第２ノードとの間の通信の中継よりも、前記複数の第１ノードの相互間の通信の中継を先に開始する。【選択図】図３
