ABSTRACT:
A skid control system for a vehicle having at least one wheel and a brake for the wheel includes a wheel speed detector for providing an output signal representative of the speed of the wheel; differentiater for differentiating the output signal of the wheel speed detector and providing an output signal representative of acceleration or deceleration of the wheel; a deceleration signal generator connected to the differentiater, the deceleration signal generator generating a deceleration signal when the output signal of the differentiater exceeds a predetermined threshold deceleration; an acceleration signal generator connected to the differentiater, the acceleration signal generator generating an acceleration signal when the output signal of the differentiater exceeds a predetermined threshold acceleration; a brake relieving circuit for decreasing the brake pressure to the brake for the wheel in response to the deceleration signal of the deceleration signal generator; a first brake control circuit for maintaining the brake pressure to the brake for the wheel constant, or gradually increasing the brake pressure to the brake for the wheel, in response to the acceleration signal of the acceleration signal generator; and a second brake control circuit for rapidly increasing the brake pressure to the brake for the wheel for a predetermined time in accordance with the slope of the output signal of the differentiator within the time when the acceleration signal generator generates the acceleration signal.
