Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent control, in particular to a control method and system of an asynchronous electric drive system, an electronic device and a storage medium. BACKGROUND

[0002] An electric vehicle (BEV for short) refers to a vehicle that uses an on-board power source (such as a lead-acid battery, a nickel-cadmium battery, a nickel-hydrogen battery, or a lithium-ion battery) as power and drives wheels with an electric motor.

[0003] To improve the power and economy of the vehicle, reduce the pitch angle of the vehicle, and improve the comfort of the vehicle, a pure electric four-wheel drive vehicle uses independent motors to drive and control the front axle and the rear axle respectively. Specifically, it mainly distributes the front and rear dual axle driving torque according to the external characteristics and efficiency curve of the motor. The electric vehicle usually does not have a clutch, and the front drive cannot be completely disconnected. In order to balance the endurance, the front auxiliary drive usually uses an asynchronous electric drive system. For example, the patent document with the publication number CN212875585U discloses a coaxial asynchronous electric drive system, which includes a speed reducer, a motor, and a main housing, and further includes a motor controller. The motor and the speed reducer are connected to form a motor speed reducer assembly and are installed in the main housing. The motor controller is fixed on the main housing and connected with the motor speed reducer assembly. The input shaft and the output shaft of the speed reducer are on the same straight line. The hollow motor shaft of the motor has a speed reducer input gear. The motor controller controls the gear on the hollow motor shaft of the motor to mesh with the intermediate shaft assembly, and then transmits the torque to the integral differential. The integral differential outputs to both sides, one side differential half shaft gear spline is connected with the vehicle half shaft, and the other side differential half shaft gear spline is connected with a short half shaft. The short half shaft passes through the motor rotor and has a spline at the exposed end of the motor to connect with the inner spline of the vehicle half shaft. It reduces the parasitic loss of the auxiliary electric drive system of the pure electric four-wheel drive vehicle and improves the endurance of the vehicle. However, even if an asynchronous electric drive is used as a front auxiliary drive, there is still excitation loss, which has a great influence on the endurance mileage. That is, this method can meet the power performance, but cannot balance the endurance mileage. SUMMARY
