[0087] In this way, the selective transmission connection between the second motor 50 and the output shaft 40 can be achieved, so that the second motor 50 can selectively transmit power to the output shaft 40, and the second motor 50 can be disconnected from the output shaft 40 in the mode in which the second motor 50 does not work, so as to reduce the oil stirring loss and improve the cruising range of the vehicle.
