A method for controlling torque in a vehicle including monitoring a plurality of factors associated with an output torque request in response to an output torque request rate of change exceeding a predetermined threshold, and controlling rate limiting of a delivered output torque to achieve the output torque request rate of change based on the plurality of factors associated with the output torque request.
