HYBRID VEHICLE

摘要

The present invention is directed to a hybrid vehicle comprising a dual clutch transmission having six forward speed stages, wherein arranged between a first input shaft and a first output shaft of the transmission are: a first gear train for a first speed stage; a third gear train corresponding for a third speed stage; a fifth gear train for a fifth speed stage; and a sixth gear train for a sixth speed stage. A second gear train for a second speed stage and a fourth gear train for a fourth speed stage are arranged between a second input shaft and a second output shaft. A first sleeve is provided between the first gear train and the third gear train; a second sleeve is provided between the fifth gear train and the sixth gear train; and a third sleeve is provided between the second gear train and the fourth gear train. A second MG is provided so as to output drive power to the second input shaft.

1. A hybrid vehicle comprising
an internal combustion engine, and a transmission as a dual clutch transmission having:
an input system including a first input shaft connected to the internal combustion engine via a first clutch and a second input shaft connected to the internal combustion engine via a second clutch;an output system connected to drive wheels in a power transmittable manner;4n+2 (n: integer one or more) sets of gear trains provided in such a way that one part of the 4n+2 sets of gear trains intervene between the first input shaft and the output system and all remaining sets of gear trains intervene between the second input shaft and the output system, the 4n+2 sets of gear trains corresponding to speed stages for forward travel respectively, the speed stages being different from each other in a gear ratio; anda plurality of connecting mechanisms, each of the plurality connecting mechanisms being provided between a pair of gear trains which are arranged next to each other within the 4n+2 sets of gear trains to selectively realize rotational transmission by one of the pair of gear trains, wherein with respect to the 4n+2 sets of gear trains, 2n+2 sets of gear trains intervene between the first input shaft and the output system, and remaining 2n sets of gear trains intervene between the second input shaft and the output system, and the hybrid vehicle further comprises an electric motor provided so as to output power to the second input shaft or the output system.
