Abstract:
A system and method for reducing wheel spin of a vehicle on slippery surfaces wherein the wheel spin is reduced by regulating the engagement of the clutches in a multiple clutch transmission of the vehicle. Upon detection by a controller of an abrupt acceleration by a driven wheel, the controller partially engages the transmission clutch which is currently disengaged, thus increasing the load on the engine and reducing the wheel spin while maintaining the drive train torque path through the previously engaged transmission clutch. Additionally, engine output is decreased upon detection of wheel spin to reduce the wear on the partially engaged clutch.
