Document Type and Number:
WIPO Patent Application WO/2023/098257
Kind Code:
A1
Abstract:
Disclosed in the present invention are a vehicle anti-skid control method, a motor controller, a system, and a storage medium. The method comprises: a motor controller determining whether an anti-skid rotating speed limiting request sent by a vehicle control unit is received; if the anti-skid rotating speed limiting request is received, starting an anti-skid driving mode to determine, according to a highest limited rotating speed and an actual rotating speed of a driving motor, whether torque reduction control is required to be performed on the driving motor; and if yes, performing closed-loop control on the torque of the driving motor according to the highest limited rotating speed and limited motor torque. According to the present invention, in the anti-skid driving mode, the motor controller determines, by itself according to the highest limited rotating speed and the actual rotating speed, whether to execute torque reduction control, and performs, during a torque reduction control process, closed-loop control on the torque of the driving motor according to the highest limited rotating speed and the limited motor torque so as to timely and accurately adjust the torque of the driving motor, so that the timeliness and effectiveness of vehicle anti-skid control are improved, and the anti-skid effect is further improved.
