PROBLEM TO BE SOLVED: To improve the accuracy of vehicle stability control during turning acceleration/deceleration.SOLUTION: A varying yaw moment generated by turning acceleration/deceleration is represented as a function of longitudinal acceleration and lateral acceleration. The longitudinal force and the lateral force of a vehicle tire have non-linear load dependency. The varying yaw moment when the load dependency is assumed to be linear is a first varying yaw moment. The varying yaw moment with the non-linear load dependency taken into consideration is a second varying yaw moment represented as the product of the first varying yaw moment and a correction gain. In vehicle stabilization control, on the basis of the longitudinal acceleration, the lateral acceleration, and the correction gain, a control device controls a yaw moment generating device so that a counter yaw moment for canceling out the second varying yaw moment is generated.SELECTED DRAWING: Figure 3

    【課題】旋回加減速時の車両安定制御の精度を向上させること。【解決手段】旋回加減速により発生する変動ヨーモーメントは、前後加速度と横加速度の関数で表される。車両のタイヤの前後力及び横力は、非線形の荷重依存性を有する。荷重依存性が線形であると仮定した場合の変動ヨーモーメントは、第1変動ヨーモーメントである。非線形の荷重依存性を考慮した変動ヨーモーメントは、第1変動ヨーモーメントと補正ゲインとの積で表される第2変動ヨーモーメントである。車両安定制御において、制御装置は、前後加速度、横加速度、及び補正ゲインに基づいて、第2変動ヨーモーメントを打ち消すためのカウンターヨーモーメントを発生するようにヨーモーメント発生装置を制御する。【選択図】図3
