Abstract
Planetary ratios of first and second planetary gear mechanisms are set such that all of the following values become equal to each other: a maximum value of a drive force of a first MG, which is generated when a total input-to-output speed ratio is a minimum value upon operation of the first MG as a motor; a maximum value of a drive force of the first MG, which is generated when the total input-to-output speed ratio is a maximum value upon operation of the first MG as the motor; and a maximum value of a drive force of the first MG, which is generated when the total input-to-output speed ratio is in a range from the minimum value to the maximum value upon operation of the first MG as a generator.
