<p>PURPOSE:To effectively decrease slipping of a vehicle by providing a driving force control means by which the driving force of the vehicle by an engine is decreased, when difference of torque is judged by a torque difference judging means to be larger than a set value. CONSTITUTION:Output shaft torque Ttheta of an automatic transmission 12 is calculated, and difference of the torque Ta between the torque Ttheta and driving torque Ts displayed by a torque sensor 20 is calculated. Judgment for driving force control is performed depending upon whether the difference of the torque Ta is larger than a set value alpha, and driving force control is performed based on an abrasion coefficient mu of the surface of the road calculated and stored before generation of slip. Before a slip rate S reaches a set value So, the generation time of the slip of the vehicle is rapidly judged in high responsiveness based on the difference of the torque Ta, and the slip of the vehicle is effectively prevented, and also an allowable maximum additional torque (limit value) can be transmitted from an engine 11 to the respective rear wheels 15.</p> |
