Abstract: A method of cooling a multi-speed dual-clutch transmission (DCT) that is paired with an internal combustion engine in a vehicle includes detecting operation of the vehicle. The method also includes sensing an increase in temperature of a subsystem of the DCT while the vehicle is operating. The method also includes selecting a remedial action in response to the sensed temperature. The method aditionally includes activating the selected remedial action such that the temperature of the subsystem is reduced.

Abstract: 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.

Abstract: A dual-clutch transmission (DCT) system includes a vehicle speed offset module that generates a vehicle speed offset signal based on a preselect time and a vehicle acceleration signal. A compensated vehicle speed module generates a compensated vehicle speed based on the vehicle speed offset signal and a vehicle speed. A preselect command module generates a predicted gear signal based on a comparison between the compensated vehicle speed and a shift point from a shift pattern module. The predicted gear signal, identifies a first predicted gear of a DCT. The preselect time is defined as at least an amount of time to disengage a second predicted gear and preengage the first predicted gear.
