PROBLEM TO BE SOLVED: To provide a collision mitigation device for mitigating collision between an own vehicle and a preceding vehicle for improving the reliability of operation determination being determination of whether to operate a controlled object and reliability as the system of the collision mitigation device.SOLUTION: An operation determination arithmetic part 15B is configured to, when a diagnostic signal is not detected, determine whether to operate a controlled object 16 on the basis of a calculation result (FSN information) by an FSN arithmetic part 14 and the vehicle state of an own vehicle input by a vehicle state input part 13. An operation determination arithmetic part 15C is configured to diagnose that operation determination by the operation determination arithmetic part 15B has been appropriately performed. When it is diagnosed that the operation determination by the operation determination arithmetic part 15B has been appropriately performed, controlling the controlled object 16 on the basis of the operation determination is permitted, and when it is diagnosed that the operation determination by the operation determination arithmetic part 15B has not been appropriately performed, controlling the controlled object 16 on the basis of the operation determination is not permitted.SELECTED DRAWING: Figure 1
【課題】自車両と先行車両との衝突を緩和する衝突緩和装置において、被制御対象を作動させるか否かの判定である作動判定および当該衝突緩和装置のシステムとしての信頼性を向上させる。【解決手段】作動判定演算部15Bは、ダイアグ信号を検出していない場合に、FSN演算部14による算出結果(FSN情報)および車両状態入力部13によって入力された自車両の車両状態に基づき、被制御対象16を作動させるか否かを判定する。作動判定演算部15Cは、作動判定演算部15Bによる作動判定が適切に行われたことを診断する。作動判定演算部15Bによる作動判定が適切に行われたと診断された場合には、当該作動判定に基づいて被制御対象16を制御することを許可する。一方、作動判定演算部15Bによる作動判定が適切に行われなかったと診断された場合には、当該作動判定に基づいて被制御対象16を制御することを許可しない。【選択図】図1
