摘要： A dual clutch transmission is provided in which at a time of pre-shifting when, while one of first and second driving force transmission paths extending from first and second input shafts to an output shaft is transmitting the driving force, the selection device for the other driving force transmission path is operated, the driving force of an internal combustion engine is changed by a command from an electronic control unit. Even if a driving force or braking force due to inertia occurs as a result of a change in the rotational speed of the first and second input shafts accompanying the pre-shifting, it is possible to reduce the shift shock by compensating for the driving force or braking force due to the inertia by changing the driving force of the engine.

摘要： A dual clutch transmission is provided in which since at a time of pre-shifting when, while running, via one driving force transmission path of first and second driving force transmission paths extending from a first and second input shafts (12, 13) to an output shaft (14), selection means (S1, S2) for the other driving force transmission path is operated, the driving force of an internal combustion engine (E) is changed by a command from an electronic control unit (U), even if a driving force or braking force due to inertia occurs as a result of a change in the rotational speed of the first and second input shafts accompanying the pre-shifting, it is possible to reduce the shift shock by compensating for the driving force or braking force due to the inertia by changing the driving force of the internal combustion engine (E). Moreover, since the shift shock can be reduced just by changing the driving force of the internal combustion engine (E) without adding a special structure to the dual clutch transmission (T), it is possible to prevent the cost and the dimensions of the dual clutch transmission (T) from increasing.
