PROBLEM TO BE SOLVED: To properly support a wheel driving shaft against cranking torque and to prevent the fluctuation of the cranking torque from transmitting to the shaft, when an internal combustion engine is cranked by a first motor generator MG1 in hybrid vehicle driving structure in which an output shaft 2 of the internal combustion engine is connected to a first motor generator MG1 and a wheel driving shaft 11 through a power distribution mechanism 3 and a second motor generator MG2 is connected to the wheel driving shaft. SOLUTION: This structure has means 51, 52, 55, 56, 100 and 101 for increasing cranking support torque that is received by the wheel driving shaft 11, other than by the second motor generator MG2, when the internal combustion engine is cranked by the first motor generator MG1. |
