Abstract
A method for controlling a transmission input clutch during a vehicle launch includes determining a desired clutch torque, a desired engine torque, a desired vehicle acceleration and a desired engine speed, determining a change in clutch torque and a change in engine torque with reference to the first and second errors and current operating conditions, applying to the clutch an updated clutch torque capacity whose magnitude is the sum of the desired clutch torque and the change in engine torque, and producing an updated engine torque whose magnitude is the sum of the desired engine torque and the change in engine torque.
