Title:
MOTOR CONTROL METHOD, APPARATUS AND DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/008527
Kind Code:
A1
Abstract:
A motor control method, comprising: when it is monitored that a vehicle enters a slope assist mode, acquiring a motor rotation speed and a motor torque value of the vehicle; determining, according to the motor rotation speed, a preload torque value corresponding to the motor rotation speed; determining, according to the motor torque value, a proportion-integration (PI) parameter value corresponding to the motor torque value, and according to the PI parameter value corresponding to the motor torque value, the motor rotation speed and a PI algorithm, calculating a torque adjustment amount; summing the preload torque value and the torque adjustment amount, and using the summation result as a torque control amount to control the motor of the vehicle, so as to enable the vehicle to be in a stationary state. Said method takes two factors, i.e. a motor rotation speed and a motor torque value, into consideration in a motor control process, so that a torque control amount is more adaptable to the requirements of a vehicle, thereby improving the stability of the vehicle. Further provided are an apparatus, a device, and a computer readable storage medium.
