Abstract
A method for controlling a powertrain of a vehicle having a dual-clutch transmission (DCT) includes: operating the DCT while the vehicle is in motion with a high or low transmission gear drivingly engaged; receiving a shift request to engage an other one of the high and low transmission gears; reducing an engine torque output and first and second clutch torques; shifting a subtransmission to a neutral gear setting; selecting a first gear or a second gear to drive the subtransmission; shifting the main transmission to engage the selected first or second gear; after shifting the main transmission, shifting the subtransmission to the other one of the high and low transmission gears; and after shifting the subtransmission, controlling the engine torque output and the first and second clutch torques according to a driver request at an accelerator of the vehicle.
