Dual-clutch transmission thermal management

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 metho...

More Information
Summary: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.
