In order to prevent an acceleration slip in an early stage of acceleration even in starting, an acceleration slip control system has a predicting section for predicting an acceleration slip of a drive wheel of a vehicle, a prediction control section for determining an initial value of a driving force reduction quantity and decreases the driving force by increasing the driving force reduction quantity to the initial value to prevent an occurrence of an acceleration slip when the acceleration slip is predicted, and a modifying section for modifying the initially set driving force reduction quantity in accordance with a sensed actual slipping condition during a prediction control of the prediction control section.
