Abstract
Driving slip rates SLi of respective wheels are calculated, and if a driving slip is excessively large is judged based on the driving slip rates SLi. Further, if a vehicle is in a predetermined turning state is judged, and if the vehicle is in an accelerating state from taking off on a road surface where a difference between coefficients of friction of the road surface with respect to the left and right wheels is large is judged. In addition, if the vehicle is in a state in which a powertrain such as a differential should be protected is judged. Fuel supply to an engine is cut until a possibility of worsening of behavior has been eliminated when the driving slip is excessively large and there is a possibility of worsening of behavior due to turning and the like, and the driving slip is reduced by reduction of driving force. Then, execution of the cutting of fuel supply is prohibited for a predetermined time after execution of the cutting of fuel supply.
