PURPOSE: To improve the movement performance and steering stability by installing a means for varying the gain represented by the rate of yaw-rate or lateral acceleration speed ratio for a steering input.
CONSTITUTION: An actuator 6 is a hydraulic servoactuator which is extended and contracted according to the signal supplied from a control circuit 7. Then, front wheels 2 are steered in supplement in the return direction by inputting a negative feedback input F into a front-wheel steering system. A gain varying means 20 varies coefficients according to the driver's liking such as car-speed condition, the traveling condition, e.g., intensity of lateral wind, weather state, and road state, and the conditions of car, e.g., acceleration/deceleration speed of car, weight of chassis, and weight distribution for the front and rear shafts, and the optimum yaw-rate gain is always secured.
