Abstract
A method of controlling the torque transferred across the engaged clutch of a vehicle having a dual clutch transmission to provide predetermined engine acceleration for each gear based on the engine throttle position and subsequent changes of clutch speed that are in response to operatively varying the torque transferred across the engaged clutch as the engine accelerates to a predetermine speed based on the throttle position. The method includes the steps of determining the engine throttle position, determining the currently engaged gear of the transmission, and sensing the speed of the driven member of the engaged clutch. Then, a target engine speed is determined based on the engine throttle position, the currently engaged gear, and the clutch speed. The torque transferred across the engaged clutch is then continuously varied to cause the engine to accelerate toward the target engine speed.
