Abstract: A method for controlling a powertrain of a vehicle, the powertrain a dual-clutch transmission including a first clutch and a second clutch selectively actuated to transmit motion from the engine to a first shaft and a second shaft respectively. The method includes producing a first shift request for shifting from an initial gear to a different gear; in response to the first shift request, executing a first shift sequence to shift from the initial gear to the different gear; during execution of the first shift sequence, producing a second shift request for shifting from the different gear to the initial gear; in response to the second shift request: interrupting the first shift sequence prior to the first shift sequence having finished; and executing a second shift sequence to reverse the first shift sequence such that the transmission engages the initial gear for driving on the first shaft.

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.

Abstract: A method for controlling an automatic transmission of a vehicle includes: sensing a speed of the vehicle; sensing an acceleration of the vehicle along three spatial axes; determining that the vehicle is in a jump state associated with the vehicle being off a ground surface, the jump state being defined at least in part by the acceleration of the vehicle along the three spatial axes and the speed of the vehicle; and controlling the transmission according to a jump strategy in response to determining that the vehicle is in the jump state. Other methods for controlling an automatic transmission of a vehicle are also contemplated.
