When the escape of the new energy vehicle is completed, i.e., the use of the winch 15 is completed, the driver again engages the parking gear to remove the torque, and engages with the second fixed transmission member 4 by controlling the first fork. At this time, the drive motor 1 is mechanically disconnected from the capstan 15 and mechanically connected to the drive output shaft, and normal mode is performed, and normal driving is resumed.
