Abstract

【課題】必要に応じてフェールセーフ処置を適度に実施する。 【解決手段】運転者が要求する加速度(要求加速度)と車両の実加速度とを求め、実加速度が要求加速度よりも大きいか否かを判別する(ステップS101〜S103)。実加速度>要求加速度の場合、運転者が危険と感じる異常であるとみなし、燃料噴射停止や燃料噴射量削減といった強めのフェールセーフ処置を実行する(ステップS104)。実加速度≦要求加速度の場合には、燃料噴射停止や燃料噴射量削減といった強めのフェールセーフ処置を実行しない。その後、センサやアクチュエータ等のシステム構成要素を対象に異常検出を実施し、センサやアクチュエータ等での異常発生が検出されると、警告ランプの点灯や車速制限といった弱めのフェールセーフ処置を実行する(ステップS105〜S107)。 【選択図】 図3
PROBLEM TO BE SOLVED: To appropriately take fail safe measures if required. SOLUTION: Acceleration required from a driver (request acceleration), and actual acceleration of a vehicle are calculated, and whether the actual acceleration is larger than the request acceleration or not is determined (steps S101 to S103). If the actual acceleration is larger than the request acceleration, it is regarded as abnormality that the driver feels risky and strong fail safe measures such as fuel injection stop and fuel injection reduction are taken (a step S104). If the actual acceleration is equal to or larger than the request acceleration, the strong fail safe measures such as fuel injection stop and fuel injection reduction are not taken. Then, abnormality detection of system components such as a sensor or an actuator is performed. If any abnormality is detected in the sensor, actuator and the like, weak fail safe measures such as lighting a warning lamp and vehicle speed restriction are taken (steps S105 to S107).
