PURPOSE:To prevent the steering angle variation of a rear wheel with high responsiveness when an external force due to the turning lateral force and the longitudinal brake power on a rear wheel such as in the brake application in the high lateral accelerating turn, in a rear wheel steering angle controller for steering the rear wheel in the front wheel steering by a hydraulic power cylinder having a centering spring. CONSTITUTION:When the high lateral accelerating speed is detected 27, nearly the max. hydraulic pressure is applied into one between the left and right oil chambers into which hydraulic pressure is applied, of a hydraulic power cylinder 4, and the stopper pressuring force due to the difference pressure portion between the applied max. hydraulic pressure and the hydraulic pressure due to the action of a stopper mechanism is set as the resistive force to the external force applied on rear wheels, and when the lateral accelerating speed exceeds a prescribed value, the pressure in one between the left and right oil chambers into which oil pressure is supplied in the hydraulic power cylinder is increased to the nearly max. oil pressure at the dill pressure increasing speed higher than the ordinary speed. |
