The invention provides a control method of a vehicle driving device and the vehicle driving device. In a shift process in which a vehicle drive device shifts between a first gear and a second gear, the control method includes: a first step of reducing a motor voltage supplied to a motor, reducing a rotational speed of a first rotational element, and reducing a rotational speed of a second rotational element when a motor torque of the motor is reversed from a current direction; one of the first clutch unit and the second clutch unit starts to be separated; and a first boosting step in which, after one of the first clutch unit and the second clutch unit is separated, the motor voltage is boosted, and the first rotating element rotates in the reverse direction after the rotational speed of the first rotating element is further reduced. According to the control method, discomfort can be relieved in the gear shifting process.

    本发明提供一种车辆驱动装置的控制方法及车辆驱动装置。在车辆驱动装置在一挡与二挡之间进行换挡的换挡过程中,控制方法包括:第一降压步骤,其中在使马达的马达扭矩自当前的方向反向时,降低向马达供给的马达电压,第一旋转元件的转速减小,第一离合单元和第二离合单元中的一者开始分离;以及第一升压步骤,其中在第一离合单元和第二离合单元中的一者分离后,升高马达电压,第一旋转元件的转速进一步减小之后反向转动。该控制方法能够在换挡过程中减轻不适感。
