ABSTRACT:
A wheel slip control apparatus for prevention of excessive wheel-slip on acceleration of a vehicle, which includes an engine-output regulating actuator and a braking force regulating actuator. The wheel slip control apparatus comprises a braking force control unit coupled to the braking force regulating actuator and an engine output control unit coupled to the engine-output regulating actuator, which operate in response to the detection of the acceleration-slip occurring with respect to the driven-wheel. The braking force control unit calculates a reference control value of a braking force to be applied to the driven-wheel on the basis of a parameter representing a state of the driven-wheel so as to suppress the acceleration-slip and generates a brake control signal indicative of the calculated braking-force reference control value. Meanwhile, the engine-output control unit is responsive to the brake control signal therefrom to calculate an engine output control amount on the basis of the braking-force reference control value and to supply an engine-output control signal indicative of the calculated engine output control amount to the engine-output regulating actuator so as to decrease the engine output by a value corresponding to the calculated braking-force reference control value.
