METHOD TO ELEVATE IDLE SPEED TO LAUNCH A VEHICLE WITH MANUAL TRANSMISSION

Abstract:

A method of controlling an idle speed for an engine of a vehicle includes the steps of sensing a vehicle speed. At least one of a parking brake position and a clutch position is also sensed. When it is determined that the vehicle speed is below a maximum vehicle speed, and either the parking brake is released or the clutch is depressed, the engine idle speed is increased from a base idle speed to a launch idle speed.
