PROBLEM TO BE SOLVED: To provide a steering angle neutral point estimation device which can estimate a neutral point of a steering angle with good accuracy.SOLUTION: A steering angle neutral point estimation device comprises: a vehicle speed sensor 11 which detects a vehicle speed of an own vehicle; a steering angle sensor 14 which detects a steering angle of the own vehicle 2; a detection condition establishment judgement part 41 which judges that a detection condition is established in the case that the on-vehicle falls within a detection time immediately after starting and the vehicle speed is a low speed of a determination threshold or less; a steering angle storage part 42 which records a steering angle when the detection condition is established; and a steering angle neutral point estimation part 43 which estimates a neutral point of the steering angle based on an average value of the steering angle when the detection condition is established.SELECTED DRAWING: Figure 6

    【課題】ステアリング角の中立点を精度良く推定可能なステアリング角中立点推定装置を提供する。【解決手段】ステアリング角中立点推定装置は、自車両の車速を検出する車速センサ11と、自車両2のステアリング角を検出するステアリング角センサ14と、自車両が発進した直後の検出時間内であり、かつ、車速が判定閾値以下の低速である場合に、検出条件が成立したと判定する検出条件成立判定部41と、検出条件が成立したときのステアリング角を記録するステアリング角記憶部42と、検出条件が成立したときのステアリング角の平均値に基づいて、ステアリング角の中立点を推定するステアリング角中立点推定部43と、を備える。【選択図】図6
