Abstract
A launch control system for a vehicle having an engine includes a clutch that selectively enables torque transfer from the engine. A control module determines a launch torque based on a throttle position and an engine speed to achieve a target engine stall speed. The control module determines a clutch torque based on the launch torque and that regulates engagement of the clutch based on the clutch torque.
