The invention discloses an automobile low-temperature transmission efficiency improving method and an automobile electric driving system. The automobile low-temperature transmission efficiency improving method is used for a hybrid electric vehicle or a pure electric vehicle, the automobile comprises a motor and lubricating oil used for lubricating the motor, and the method comprises the steps that in the heating process of the automobile, the lubricating oil passes through the motor, the motor is locked, so that the motor is heated, and the lubricating oil passing through the motor is heated. According to the automobile low-temperature transmission efficiency improving method and the automobile electric driving system, when the temperature is low, in the automobile heating process, the motor is subjected to stalling and heating, lubricating oil passing through the motor is heated, the temperature of the lubricating oil is increased, the viscosity of the lubricating oil is reduced, and thus oil stirring loss and dragging loss of an automobile can be reduced. And the low-temperature transmission efficiency of the automobile is improved.

    本发明公开一种汽车低温传动效率改善方法及汽车电驱动系统,所述汽车低温传动效率改善方法用于混合动力汽车或纯电动汽车,所述汽车包括电机、用以润滑所述电机的润滑油,所述方法包括:在所述汽车热车过程中,所述润滑油经过所述电机,所述电机堵转,使所述电机发热,实现经过所述电机的所述润滑油加热。本发明提供的汽车低温传动效率改善方法及汽车电驱动系统在温度较低时,通过在汽车热车过程中,让电机堵转,使电机发热,实现经过电机的润滑油加热,提高了润滑油温度,降低了润滑油的粘度,从而能够降低汽车的搅油损失和拖拽损失,改善汽车的低温传动效率。
