ABSTRACT:
A slip value of a driving wheel is calculated on the basis of driving and driven wheel velocities detected by wheel velocity sensors. A target engine output of a vehicle is set in accordance with the slip value of the driving wheel. A target fuel amount to the engine is set in accordance with the target engine output. A target opening of a throttle valve is set based on the target fuel amount. An opening correction value of the throttle valve is calculated in accordance with a deviation between the target fuel amount and an actual fuel amount to the engine detected by a fuel controller. A traction controller controls to cause the engine output to coincide with the target engine output by ontrolling the opening of the throttle valve to attain an opening as a sum of the target opening and the opening correction value.
