| description | A method of controlling the performance of a vehicle from a stationary condition includes operating a vehicle powertrain in a creep mode following the disengagement of a driver-operated braking device; and operating the vehicle powertrain in a launch mode following an engagement of a driver-operated acceleration device subsequent to the disengagement of the driver-operated braking device. Operating a vehicle powertrain in a creep mode includes: applying a friction clutch to couple an engine crankshaft of the vehicle powertrain with an input shaft of the transmission; determining a torque command to accelerate the vehicle powertrain at a predetermined rate; providing the torque command to an engine controller to controllably increase the input torque to the transmission; and operating a closed loop engine speed control module to prevent the crankshaft speed from slowing below a predetermined engine idle speed. |
