ABSTRACT:
A driving wheel rotational speed and a driven wheel rotational speed are detected by corresponding wheel speed sensors to calculate a slip value DV of driving wheels. A target output torque of an engine of a vehicle is calculated on the basis of the slip value DV. A target intake air amount per a predetermined number of revolutions of the engine is set in accordance with the target torque. Opening correction of a throttle valve is performed at every control cycle time .DELTA.t on the basis of an difference between a target intake air amount per the predetermined number of revolutions of the engine and an actual intake air amount per the predetermined number of revolutions of the engine in the controller. The opening of the throttle valve is increased/decreased in accordance with the opening correction value .DELTA..theta.ti by the motor drive circuit.
