To prevent the direction of drive torque of a drive wheel from being reversed when a plurality of drive wheels are driven in a configuration in which the plurality of drive wheels are connected to a power source via a differential gear.SOLUTION: A vehicle includes: a first rotary electric machine, a second rotary electric machine, a differential device having three rotary elements; and a control device that controls the first rotary electric machine and the second rotary electric machine. When the control device executes dual drive control for driving the first rotary electric machine and the second rotary electric machine, the vehicle drives a first drive wheel and a second drive wheel while positive torque from the first rotary electric machine and negative torque from the second rotary electric machine act on a third rotary element. When executing dual drive control, the control device executes control so that drive torque of the first drive wheel becomes positive toque.SELECTED DRAWING: Figure 4 【課題】複数の駆動輪が差動装置を介して動力源に連結された構成において、複数の駆動輪を駆動する際、駆動輪の駆動トルクの方向が逆向きにならないようにすること。【解決手段】第１回転電機、第２回転電機と、三つの回転要素を有する差動装置と、第１回転電機と第２回転電機とを制御する制御装置と、を備え、制御装置が、第１回転電機と第２回転電機とを駆動する両駆動制御を実行する場合には、第３回転要素に第１回転電機からの正トルクおよび第２回転電機からの負トルクが作用する状態で第１駆動輪と第２駆動輪とを駆動する車両であって、制御装置は、両駆動制御を実行する際に第１駆動輪の駆動トルクが正トルクとなるように制御する。【選択図】図４
