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.
