摘要： 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.

摘要： A planetary gear mechanism has a first planetary gear train that includes a ring gear to which power from a main power source is input, a planetary carrier that is connected to a first output shaft, a first planetary pinion that is turnably supported by the planetary carrier, and a first sun gear that is connected to a distribution electric motor. The planetary gear mechanism also has a second planetary gear train that includes the ring gear, the planetary carrier, the first planetary pinion, a second planetary pinion that is turnably supported by the planetary carrier, and a second sun gear that is connected to a second output shaft.

摘要： A target value obtaining section obtains a target value for the difference in rotational motion between a first motor and a second motor and a target value for output torque. A torque command value calculating section calculates a torque command value for the first motor and a torque command value for the second motor that achieve both of the target value for the difference in rotational motion and the target value for the output torque by using an inverse model of a motion model corresponding to a merging system.
