Abstract:
A control system for a vehicle, comprises a torque determination module, a control module, and a transmission control module. The torque determination module determines torque produced by an internal combustion engine. The control module sets a signal to an active state when the torque is greater than a predetermined torque and a slip amount between an engine output speed and a transmission input speed is zero. The predetermined torque corresponds to a potential vibration amount when the slip amount is zero. The transmission control module selectively increases the slip amount above zero in response to the setting of the signal to the active state.
