Title:
DRIVING ELECTRIC MOTOR CONTROL METHOD AND APPARATUS, AND STORAGE DEVICE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/001011
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electric motor control. Provided are a driving electric motor control method and apparatus, and a storage device and a vehicle. The driving electric motor control method comprises: determining a total optimization torque according to a target torque required by a vehicle; acquiring a mapping table of the torque and efficiency, which correspond to an actual rotational speed of any driving electric motor in the vehicle, of the driving electric motor; under the total optimization torque, by taking the maximum sum of efficiencies corresponding to M first candidate torques and N second candidate torques as an optimization target, traversing the mapping table of the torque and efficiency of the driving electric motor, and selecting an optimal combination of the first candidate torques and the second candidate torques; and on the basis of the optimal combination, determining a target torque of each front driving electric motor and a target torque of each rear driving electric motor. The present invention is used for solving the defects in the prior art of it being impossible to determine the torques of two or more driving electric motors and the application range being narrow, such that the torques of two or more driving electric motors are determined, and the application range is broader.
