Abstract
A traction control system of a vehicle having a device for calculating a target traction torque of each of a pair of driving wheels based upon operating conditions of the vehicle, a device for calculating a target slip ratio of each of the pair of driving wheels based upon the target traction torque calculated therefor, and a device for controlling the engine and the brake system such that actual slip ratio of each of the pair of driving wheels coincides with the target slip ratio calculated therefor according to a feedback control, with a partial feedforward control of the engine and the brake system based upon the target traction torque.
