To improve safety on security when a redundant system is activated while maintaining travel control (for example, automated driving) of an automobile by an on-vehicle control system.SOLUTION: An electronic control device 140 is mounted on an on-vehicle control system 10 that controls traveling of an automobile, and is communicatively connected to a plurality of control devices including a first control device (electronic control device 120) and a second control device (electronic control device 130). The electronic control device 140 includes: an attack determination unit 145 that determines whether there is a security attack on each control device; and a redundant system execution determination unit 146 that determines based on a determination result by the attack determination unit 145 whether a redundant function that is the same as or a part of a function performed by the first control device should be performed by the second control device instead.SELECTED DRAWING: Figure 1
【課題】車載制御システムによる自動車の走行制御(例えば自動運転)を維持しつつ、冗長系起動時のセキュリティ上の安全性を向上させる。【解決手段】電子制御装置140は、自動車の走行制御を行う車載制御システム10に搭載され、第1の制御装置(電子制御装置120)及び第2の制御装置(電子制御装置130)を含む複数の制御装置と通信可能に接続される。電子制御装置140は、各制御装置におけるセキュリティ攻撃の有無を判定する攻撃判定部145と、攻撃判定部145による判定結果に基づいて、第1の制御装置が担っていた機能と同様またはその一部の機能による冗長機能を、第2の制御装置に代替して実行させるか否かを判定する冗長系実行判定部146と、を備える。【選択図】図1
