<P>PROBLEM TO BE SOLVED: To shorten a speed-change time and improve speed-change performance of a hybrid vehicle. <P>SOLUTION: The drive device of the hybrid vehicle comprises an engine 10, a transmission 13, a first motor generator 11 arranged therebetween, and a battery 23 capable of discharging and being charged to/from the first motor generator 11. When an estimate value of an output voltage of the first motor generator 11 exceeds a predetermined voltage in shifting the transmission 13, the battery 23 is electrically separated from the drive device, a voltage of a power line 25 on a side of the first motor generator 11 is decreased, and power is charged in the battery 23. <P>COPYRIGHT: (C)2007,JPO&INPIT |
