METHOD AND SYSTEM FOR LIMITING BELT SLIP IN A CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A method of limiting belt slip in a continuously variable transmission (CVT) of a vehicle. The CVT is operatively connected to an engine. The method includes determining a slip speed of a belt of the CVT, determining the accumulated energy based on the slip speed of the belt and an engine torque produced by the engine, and controlling the engine torque in an intervention mode when the accumulated energy is greater than a threshold energy. Controlling the engine torque in an intervention mode comprises controlling at least one of cycling the engine torque, and limiting the engine torque. Systems and vehicles for performing the method are also disclosed.
