Patent ID: 8626417

Claim:
A motor vehicle, comprising: a drivetrain including a power unit generating a drive torque; a set of first wheels driven by the drive torque generated by the power unit; a set of second wheels; a torque sensor for producing a traction torque signal in response to the drive torque; a speed sensor for producing a wheel speed signal in response to rotation of the set of second wheels; a throttle control unit operable to control the drive torque generated by the power unit in response to a throttle control signal; and a traction control system operable to detect a lost traction condition at the set of first wheels and generate a desired throttle control signal in response thereto, said traction control system is operable to read first and second traction torque signals generated by said torque sensor, determine whether the lost traction condition has occurred within a predetermined time period based on a sustained reduction in value between the first and second traction torque signals, determine whether the sustained reduction is attributable to a change in at least one of a throttle position, a gear change and a brake engagement, calculate the desired throttle control signal when the sustained reduction is not attributable to a change in any of the throttle position, the gear change and the brake engagement, and send the desired throttle control signal to the throttle control unit for reducing the drive torque generated by the power unit.
