PROBLEM TO BE SOLVED: To improve vehicle responsiveness, driver feeling, or the like by controlling yaw and lateral movements in consideration of a vehicle body lateral sliding angle.SOLUTION: A method of controlling vehicle behavior includes the steps of obtaining a vehicle speed, obtaining an actual steering angle of a wheel for a steering operation, and controlling yaw and lateral movements of the vehicle in accordance with an integrated value, which is obtained by integration of (1) a first parameter indicating a gain of a vehicle body lateral sliding angle generated by the actual steering angle and (2) a second parameter indicating a transient change of the vehicle body lateral sliding angle due to a change of the actual steering angle. The first parameter and the second parameter regulate, based on the obtained vehicle speed and the obtained actual steering angle, a transfer function of the vehicle body lateral sliding angle to the actual steering angle.SELECTED DRAWING: Figure 4
【課題】車体横すべり角を考慮してヨー運動及び横運動を制御することで、車両応答性やドライバのフィーリング等を向上させる。【解決手段】車両挙動の制御方法は、車速を取得する工程と、ステアリングの操舵に対応する車輪の実舵角を取得する工程と、取得された車速及び実舵角に基づき、実舵角に対する車体横すべり角の伝達関数を規定する、(1)実舵角により生じる車体横すべり角のゲインを示す第1パラメータと、(2)実舵角の変化に起因する車体横すべり角の過渡的変化を示す第2パラメータと、を積算した値に応じて、車両のヨー運動及び横運動を制御する工程と、を有する。【選択図】図4
