Abstract:
A speed ratio containment process limits the speed ratio of a variator for a CVT for a motor vehicle when rolling backward by commanding a speed ratio that is higher than the actual speed ratio in an overdrive direction. Accordingly, the actual speed ratio moves to a lowest limit, which provides maximum torque when a driver of the motor vehicle steps on the accelerator pedal to resume forward motion of the motor vehicle.
