Zusammenfassung:A control system for a vehicle having a dry dual clutch transmission (DCT) includes a launch condition detection module, a vehicle stop module, and a vehicle launch module. The launch condition detection module detects a launch condition based on whether (i) the vehicle is on an uphill grade and (ii) a driver of the vehicle has requested power via an accelerator. The vehicle stop module stops the vehicle when the launch condition is detected by (i) commanding an on-coming clutch of the dry DCT to a predetermined position and (ii) applying brakes of the vehicle. The vehicle launch module launches the vehicle after the vehicle is stopped by (i) fully engaging the on-coming clutch of the dry DCT and (ii) opening a throttle to a desired position corresponding to the power request.
