Abstract
A vehicle driving apparatus includes a first motor, a second motor, and a planetary mechanism, and obtains a driving force by combining motive forces obtained from the first motor and the second motor by a planetary gear of the planetary mechanism. The vehicle driving apparatus includes at least one of a design value and a control quantity in which a frequency ratio between a sound generated by a rotation of the first motor and a sound generated by a rotation of the second motor satisfies a reduction condition of dissonance.
