ABSTRACT:
An anti-skid control system for a vehicle with at least one wheel. The anti-skid control system includes a wheel sensor for sensing a rotational speed of the wheel and for generating a signal indicative of the sensed wheel speed and a brake sensor for sensing a braking force of a braking device which brakes the wheel and for generating a signal indicative of the sensed braking force. The wheel sensor and the brake sensor are respectively coupled to a control unit for receiving the wheel speed signal and the braking force signal to control the braking force of the braking device to a target braking force so that a slip ratio of the wheel assumes a predetermined value. The control unit determines the target braking force at the time of start of the anti-skid control to be equal to a braking force corresponding to the resultant of torques developed in the wheel at the control start time.
