<P>PROBLEM TO BE SOLVED: To perform high quality retreat travel in the event of a failure of a motor generator for inputting/outputting power with a drive shaft. <P>SOLUTION: A hybrid vehicle 10 includes a dog clutch 360 on an output shaft 320 of a power dividing mechanism 300, and is composed such that either a motor generator MG2 or a motor generator MG3 is selectively connected to the output shaft 320. The power dividing mechanism 300 includes a variable transmission mode and a fixed transmission mode as a transmission mode. The MG3 is connected to the output shaft 320 in the fixed transmission mode, and the MG2 is connected to the output shaft 320 in the variable transmission mode. Therefore, the MG3 is composed such that its generation efficiency is higher than that of the MG2 in the operation condition of the output shaft 320 corresponding to the fixed transmission mode. In the retreat travel control when the MG2 is in a failed state, an ECU 100 controls the dog clutch 360 such that the MG3 is connected to the output shaft 320 even in the variable transmission mode. <P>COPYRIGHT: (C)2009,JPO&INPIT |
