Vehicle With Dual Clutch Transmission

This example shows a vehicle with a five-speed automatic dual-clutch transmission. The transmission controller converts the pedal deflection into a demanded torque. This demanded torque is then passed to the engine management. The pedal deflection and the vehicle speed are also used by the transmission controller to determine when the gear shifts should occur. Gear shifts are implemented via the two clutches, one clutch pressure being ramped up as the other clutch pressure is ramped down. In a dual clutch transmission, gear pre-selection is used to ensure that the correct gear is fully selected before the on-going clutch is enabled.
