ON-VEHICLE CONTROL DEVICE

PROBLEM TO BE SOLVED: To obtain an on-vehicle control device which can quickly and accurately determine whether or not a thrust force of a drive source of a vehicle is abnormal without being affected by a change of a traveling state of the vehicle.SOLUTION: An estimation generation torque calculation part 111 calculates a change amount of an actual estimation operation state amount of an engine 201, and an allowable generation torque calculation part 110 calculates an allowable operation state change amount which is obtained from a drive operation amount. Allowable operation state amount phase change processing parts (501 to 511) change a phase of the allowable operation state amount, and change the allowable operation state change amount so as to make the allowable operation state amount coincide with the phase of the estimation operation state change amount, an abnormality detection part 112 sets a difference 916 between a change amount of the estimation operation state amount and the changed allowable operation state change amount as an index value, and the abnormality detection part 112 compares the index value (difference 916) and predetermined determination thresholds (threshold 1, threshold 2). By this constitution, an abnormal state of the generation torque of the engine 201 is detected.SELECTED DRAWING: Figure 3 【課題】車両の走行状態の変化に影響を受けずに車両の駆動源の推進力が異常であるか否かを迅速に精度よく判定することのできる車載制御装置を実現する。【解決手段】推定発生トルク算出部111がエンジン201の実際の推定作動状態量の変化量を算出し、許容発生トルク計算部110が運転操作量から求められた許容作動状態変化量を算出する。許容作動状態量位相変更処理部（501〜511）が、許容作動状態量を推定作動状態の変化量の位相に一致するように、許容作動状態量の位相を変更し、許容作動状態変化量を変更し、異常検出部112が、推定作動状態量の変化量と変更した許容作動状態変化量との差分916を指標値とし、異常検出部112が指標値（差分916）と予め定めた判定閾値（閾値1、閾値2）と比較する。これにより、エンジン201の発生トルクの異常状態を検出する。【選択図】図３
