Motor control method, device and equipment and computer readable storage medium

Abstract

The embodiment of the invention provides a motor control method, device and equipment and a computer readable storage medium. The method comprises the steps: collecting the motor rotating speed and motor torque of a vehicle when the vehicle is monitored to enter a ramp auxiliary mode; determining a pre-added torque value corresponding to the rotating speed of the motor according to the rotating speed of the motor; determining a PI parameter value corresponding to the motor torque value according to the motor torque value, and calculating a torque adjustment amount according to the PI parametervalue corresponding to the motor torque value, the motor rotating speed and a PI algorithm; and summing the pre-added torque value and the torque adjustment amount, and controlling a motor of the vehicle by taking a summing result as a torque control amount to enable the vehicle to be in a static state. According to the embodiment of the invention, factors in two aspects of the motor rotating speed and the motor torque value can be considered in the motor control process, so that the torque control quantity better meets the vehicle requirements, and the vehicle stability is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle control, and in particular to a motor control method, device, equipment and computer-readable storage medium. Background technique [0002] When the vehicle starts on a slope, during the process from releasing the brake pedal to stepping on the accelerator pedal, there will be a phenomenon that the direction of the vehicle is inconsistent with the driving gear, that is, the vehicle will roll, which may easily cause safety accidents. [0003] In the prior art, usually when the vehicle slipping is detected, the vehicle controller increases the target torque value to the motor controller, and at the same time increases the target torque gradient to quickly stop the vehicle from slipping. [0004] However, in the prior art, increasing the target torque value and target torque gradient can quickly stop the vehicle from rolling, but since the target torque value and target torq...
