1. A method for controlling a powertrain of a vehicle, the powertrain comprising:
an internal combustion engine; and
a dual-clutch transmission operatively connected to the engine, the dual-clutch transmission comprising:
a first clutch and a second clutch selectively actuated to transmit motion from the engine to a first shaft and a second shaft respectively;
at least one first gear mounted to the first shaft; and
at least one second gear mounted to the second shaft,
the method comprising:
producing a first shift request for shifting the dual-clutch transmission from an initial gear to a different gear, the initial gear being engaged on the first shaft, the initial gear being one of the at least one first gear, the different gear being one of the at least one second gear;
in response to the first shift request, executing a first shift sequence to shift the dual-clutch transmission from the initial gear to the different gear;
during execution of the first shift sequence, producing a second shift request for shifting the dual-clutch transmission 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 dual-clutch transmission engages the initial gear for driving on the first shaft.
