ABSTRACT:
A slip control system for a motor vehicle controls respective braking forces in right and left driving wheels and controls an engine output by controlling a throttle opening of a throttle valve so that a slip value of the driven wheel becomes less than a target slip value. The system includes a device providing a basic control amount of the throttle opening based on the slip value of the driven wheel and the target slip value, a device for detecting respective brake fluid pressures in the right and left driven wheels, a device for converting the detected brake fluid pressure into an engine output, a device for providing a correction control amount of the throttle opening by subtracting an amount of the throttle opening corresponding to the converted engine output from the basic control amount of the throttle opening, and a device for driving the throttle valve by the basic control amount of the throttle opening when the brake fluid pressures in the right and left driven wheels are increased or increased rapidly, and driving the throttle valve by the correction control amount of the throttle opening when the brake fluid pressures in the right and left driven wheels are not increased or increased rapidly.
