ABSTRACT:
A wheel slip control system used for a vehicle comprising: a pressure source selector being informed of a first pressure of a first pressure source and a second pressure of a second pressure source and adapted to select one of the first and second pressure source, a slip controller receiving a first adjustment signal for anti-skid control to adjust the first pressure provided by the pressure source selector or receiving a second adjustment signal for traction control to adjust the second pressure provided by the pressure source, selector a brake slip detector detecting the state of slipping of wheels during a braking operation of the vehicle and producing a brake slip signal, an acceleration slip detector detecting the state of slipping of wheels during an accelerating operation of the vehicle, a second throttle valve being placed at an intake air path provided with a first throttle valve interlocked to an acceleration increase member; and an electronic controller receiving the brake slip signal and providing the first adjustment signal for the slip controller so that the driven wheel speed is within a first predetermined range, receiving the acceleration slip signal and providing the second adjustment signal for the slip controller so that the driven wheel speed is within a first predetermined range, and providing the third adjustment signal to a driving member for driving the second throttle valve for the slip controller so that the driven wheel speed is within a second predetermined range.
