<P>PROBLEM TO BE SOLVED: To transmit torque during shifting operation without lowering the loss of a transmission. <P>SOLUTION: In this vehicular drive apparatus, at least two motor generators 3, 5, a main power source 1, and an output shaft for a driving system, are connected to one another via at least one planetary gear, and one motor generator 5 out of at least two motor generators 3, 5 is connected to the planetary gear via a step-shifting transmission 6 having a plurality of steps, and the speed ratio of the main power source 1 to the output shaft for the driving system can be set non-stepwise. The step-shifting transmission 6 has a dog clutch 8 as at least one step of fastening element, and a semi-fastening element 7 as at least one step of fastening element for transmitting torque in a slipping condition. <P>COPYRIGHT: (C)2010,JPO&INPIT |
