PROBLEM TO BE SOLVED: To improve a speed of converging a sensor output value to a true value while suppressing the occurrence of a driver's discomfort for a change in a vehicle acceleration/deceleration resulting from correction of an output value from an acceleration sensor.SOLUTION: An offset estimation value Gos of an acceleration sensor 2 mounted in a vehicle and detecting an acceleration of the vehicle is calculated, and a sensor output value Ga is corrected by adding a correction value CL to the sensor output value Ga so as to cancel the offset estimation value Gos. At the time of the correction, a magnitude of the correction value CL is restricted on the basis of a driver sensitivity sensitive value term Ds that is an index value of a driver sensitivity sensitive value higher as an operation state of a brake/drive force indication operator indicating a brake force or drive force of the vehicle is in a change state of increasing a change rate of an acceleration or deceleration of the vehicle if a direction of the acceleration or deceleration of the vehicle resulting from the operation state of the brake/drive force indication operator is the same as a direction of the acceleration or deceleration of the vehicle resulting from the correction.
【課題】加速度センサの出力値の補正に起因した車両の加減速度の変化に対するドライバの違和感の発生を抑えつつ、センサ出力値の真値への収束速度を向上する。【解決手段】車両に搭載され該車両の加速度を検出する加速度センサ２のオフセット推定値Ｇｏｓを算出し、このオフセット推定値Ｇｏｓが打ち消されるようにセンサ出力値Ｇａに補正値ＣＬを加算することで補正を行う。その際に、車両の制駆動力を指示する制駆動力指示操作子の操作状態に基づき、該操作状態に起因した車両の加速又は減速の方向と、補正に起因した車両の加速又は減速の方向とが同じ方向のときに、制駆動力指示操作子の操作状態が、車両の加減速度の変化率が大きくなる変化状態であればあるほど小さくなるドライバ感度感応値、の指標値であるドライバ感度感応項Ｄｓに基づき補正値ＣＬの大きさを制限する。【選択図】 図３
