A traction control system for limiting the slip of a driven wheel determines an excessive spinning condition of the wheel in response to an excess driving torque applied from the vehicle engine. If the vehicle speed is less than a predetermined value, a braking force is applied to the wheel that is a predetermined function of the spin ratio of the wheel and when the vehicle speed is greater than the predetermined value, a braking force is applied to the wheel that is a predetermined function of the difference between the driven wheel speed and the vehicle speed.

A traction control system for a vehicle having an engine for applying a driving torque to a vehicle driven wheel, the system comprising, in combination: a wheel speed sensor for measuring driven wheel speed Vf; a vehicle speed sensor for measuring vehicle speed Vr; means responsive to the measured driven wheel speed for determining driven wheel acceleration af; means responsive to the measured vehicle speed for determining vehicle acceleration ar; means for determining a spin ratio value of the driven wheel in accord with the expression (Vf-Vr)/Vf; means for determining an excessive spinning condition of the driven wheel in response to an excessive driving torque applied thereto from the engine; and means responsive to a determined excessive spinning condition for applying a braking force to the driven wheel having a value (A) that is a predetermined function of the value of the expression af-ar and the determined spin ratio value when the vehicle speed is less than a predetermined value and (B) that is a predetermined function of the value of the expression af-ar and the value of the expression Vf-Vr when the vehicle speed is greater than the predetermined value.
