1. A method for operating a vehicle comprising a dual-clutch transmission (DCT), the DCT comprising:
a clutch input member operatively connected to an engine of the vehicle;
a first clutch;
a second clutch;
a first shaft operatively connected to the first clutch, the first clutch being selectively actuated to couple the first shaft to the clutch input member;
a second shaft operatively connected to the second clutch, the second clutch being selectively actuated to couple the second shaft to the clutch input member;
at least one first driving member mounted to the first shaft;
at least one second driving member mounted to the second shaft; and
an output shaft operatively connecting the at least one first driving member and the at least one second driving member to at least one of a plurality of ground-engaging members of the vehicle;
the method comprising:
determining if the vehicle is substantially stationary based on at least one operating parameter of the vehicle; and
in response to determining that the vehicle is substantially stationary, actuating the first clutch and the second clutch to cause simultaneous driving engagement of both the first shaft and the second shaft with the output shaft to thereby lock the output shaft.
