The invention discloses a motor drive system with automatic switching capacity and a control method thereof. The motor drive system is used for an electric vehicle. The motor drive system comprises a first motor, a second motor, a vehicle controller and a charge and discharge system. The vehicle controller controls the first motor and the second motor to drive or brake the electric vehicle. The charge and discharge system supplies power to the electric vehicle and receives electric energy released by the first motor and the second motor when the vehicle is braked. The first motor and the second motor are each of a double-output-shaft structure. One end of the first motor is connected with a load device, and the other end of the first motor is connected with an input shaft of the second motor through a clutch and a transmission shaft. The output shafts of the second motor are connected with a main speed reducer of the vehicle through a reduction gearbox or directly connected with the main speed reducer. The motor drive system can generate large torque when the vehicle works at a low speed and has proper power when the vehicle is operated at medium and high speeds.
