To provide a steering auxiliary system which is capable of improving response characteristics at the start of steering, while suppressing power consumption, and further, capable of improving vehicle responsiveness, straight line stability, and ride comfort in all steering regions including the start of steering.SOLUTION: A steering auxiliary system includes: a motor generator 102; and a control device 111 for controlling the motor generator 102 so that a vehicle is caused to generate yaw angular velocity and longitudinal acceleration. The steering auxiliary system provides assisted steering according to a steering device 107. In the control device 111, an attenuation factor correction parameter is an inverse number of a natural frequency correction parameter, and the natural frequency correction parameter only is a control parameter of the yaw angular velocity. The control device 111 has a control unit 110 which changes a ratio of the yaw angular velocity to the longitudinal acceleration that are to be generated by the vehicle 1, in accordance with a product of steering angular velocity and steering angular acceleration.SELECTED DRAWING: Figure 1

    【課題】電力消費量を抑制しつつ、操舵開始時の応答特性の改善が可能で、さらに操舵開始時を含めた全ての操舵領域で車両応答性、直進安定性、乗り心地の向上を図ることができる操舵補助システムを提供する。【解決手段】操舵補助システムは、電動発電機102と、ヨー角速度および前後加速度を車両に発生させるように電動発電機102を制御する制御装置111とを備え、ステアリング装置107による操舵の補助を行う。制御装置111は、減衰率補正パラメータを固有振動数補正パラメータの逆数とし、固有振動数補正パラメータのみをヨー角速度の制御パラメータとする。制御装置111は、操舵角速度と操舵角加速度の積に応じて、車両1に発生させるヨー角速度と前後加速度の比率を変更する制御器110を有する。【選択図】図1
