Title:
BUSBAR CURRENT CONTROL METHOD, APPARATUS AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/273550
Kind Code:
A1
Abstract:
Provided are a busbar (202) current control method, apparatus and system, and a storage medium. The control method comprises the following steps: acquiring a data set, the data set comprising the rotational speed, actual current, and actual torque of a motor (201) corresponding to the current time point; determining a limiting current at the current time point according to the rotational speed of the motor (201); if the limiting current is less than the actual current, then determining, according to the limiting current and the actual current, the deviation value of the current time point; determining a target request torque on the basis of the deviation value and the actual torque; and determining a busbar (202) current according to the target request torque. Therefore, the busbar (202) current can be limited within a safe range by dynamically adjusting the limiting current and the target request torque, and the present invention has the advantages of effectively controlling the busbar (202) current and also ensuring the effectiveness of vehicle (10) parts.
