PURPOSE:To obtain a flat yaw-rate gain and permit the accurate following of behavior of a car to a steering input by applying negative feedback according to the sum value of yaw-rate or lateral acceleration speed and its differentiation value. CONSTITUTION:An actuator 6 applies negative feedback onto a front-wheel steering system according to the sum value of yaw rate or lateral acceleration speed and its differentiation value and steers front wheels 2 in supplement in the return direction. Therefore, even if response delay or the damping of signal in high-frequency range is generated in each constitution element, these defects can be offset by the differentiation value as rapid signal, and the delay of negative feedback input F for the detected behavior by a sensor 3 is eliminated, and the aimed yaw-rate gain and phase-lag characteristic can be obtained. |
