One aspect of a drive device according to the present invention is a drive device that rotates an axle of a vehicle, the drive device comprising: a motor; a speed reducer connected to the motor; a differential connected to the motor via the speed reducer; a housing that internally accommodates the motor, the speed reducer, and the differential; an oil pump that is accommodated within the housing and that feeds oil to the motor; and a control unit that controls the motor. The control unit drives the oil pump after an ignition switch of the vehicle is turned off. Selon un mode de réalisation, la présente invention concerne un dispositif de transmission qui fait tourner un essieu d'un véhicule, le dispositif de transmission comprenant: un moteur; un réducteur de vitesse relié au moteur; un différentiel connecté au moteur à travers le réducteur de vitesse; un carter qui reçoit intérieurement le moteur, le réducteur de vitesse et le différentiel; une pompe à huile qui est reçue à l'intérieur du carter et qui alimente en huile le moteur; et une unité de commande qui commande le moteur. L'unité de commande active la pompe à huile après l'extinction d'un commutateur d'allumage du véhicule. 本発明の駆動装置の一つの態様は、車両の車軸を回転させる駆動装置であって、モータと、モータに接続される減速装置と、減速装置を介してモータに接続される差動装置と、モータ、減速装置、および差動装置を内部に収容するハウジングと、ハウジングの内部に収容されたオイルをモータに送るオイルポンプと、モータを制御する制御部と、を備える。制御部は、車両のイグニッションスイッチがＯＦＦにされた後において、オイルポンプを駆動する。
