Abstract:
An improved traction control system for a vehicle, including a driven wheel speed regulating means capable of regulating driven wheel speeds by varying braking forces for driven wheels in accordance with excessive slipping of the driven wheels, the improvement comprising:a detecting means for detecting that a driver has operated an engine output to reduce the driven wheel speed; anda control unit which controls to stop a traction control in response to said detecting means having detected the driver's operation to reduce the driven wheel speed during carrying-out of the traction controlwherein said control unit is arranged such that in a state in which the driver's operation to reduce the driven wheel speed is not detected by the detecting means, the traction control is started in accordance with the driven wheel exceeding a first threshold value set to be greater than a target wheel speed, but when the driver's operation to reduce the driven wheel speed has been detected by the detecting means, the traction control is started in accordance with the driven wheel speed exceeding a second threshold value set to be greater than the first threshold value.
