ON-VEHICLE DEVICE, CONNECTION DESTINATION NOTIFICATION METHOD AND CONNECTION DESTINATION NOTIFICATION PROGRAM

To improve a power saving function in an on-vehicle relay device.SOLUTION: An on-vehicle device is used in an on-vehicle network including an on-vehicle relay device that relays a frame that is transmitted and received between on-vehicle function parts. The on-vehicle relay device includes a communication port group including a plurality of communication ports and a communication circuit group including a plurality of communication circuits provided on the plurality of communication ports respectively. The communication circuit group includes a plurality of object communication circuits in which kinds of sleep modes need to be unified. The communication port group includes a plurality of object communication ports corresponding to the plurality of object communication circuits respectively. There is provided a notifying part that when a new function part is connected to the object communication port to which the existing function parts are not connected, in a state where the existing function parts are connected to some of the plurality of object communication ports, notifies an operator of the communication port to which the new function part should be connected, on the basis of a combination of the kinds of sleep modes which are applied to the plurality of object communication circuits.SELECTED DRAWING: Figure 2 【課題】車載中継装置における省電力機能を向上させる。【解決手段】車載機能部間で送受信されるフレームを中継する車載中継装置を含む車載ネットワークに用いられる車載装置であって、車載中継装置は、複数の通信ポートを含む通信ポート群と、前記複数の通信ポートにそれぞれ対応して設けられる複数の通信回路を含む通信回路群とを含み、前記通信回路群は、スリープモードの種類を統一する必要がある複数の対象通信回路を含み、前記通信ポート群は、前記複数の対象通信回路にそれぞれ対応する複数の対象通信ポートを含み、前記複数の対象通信ポートのうちの一部に既存機能部が接続された状態において、前記既存機能部が接続されていない前記対象通信ポートに新規機能部が接続された場合、前記複数の対象通信回路に適用される前記スリープモードの種類の組み合わせに基づいて、前記新規機能部の接続先とすべき前記通信ポートを通知する通知部を備える。【選択図】図２
