ABSTRACT:
The present invention relates to launch control of a vehicle having an automated manual transmission and an automated clutch selectively engaging an output of an engine to an input of the transmission. When a request for vehicle launch is detected, an output speed of the automated clutch and a desired clutch output torque are obtained. The automated clutch is partially engaged to allow for slip between an input to the clutch and an output from the clutch, and a desired amount of the slip between the input to the clutch and the output from the clutch is determined. A desired engine speed is calculated based on the desired amount of slip, with the engine torque automatically adjusted to obtain the desired engine speed.
