Motor drive control method and system for torque margin discharge and storage medium

The embodiment of the invention provides a motor drive control method and system for torque margin discharge and a storage medium, and belongs to the field of automobiles, and the method comprises the steps that a VCU receives a parking instruction, requests a speed ring working mode and a target rotating speed; the MCU executes a speed ring working mode; pI adjustment is carried out according to the target rotating speed, and execution torque is output; and parking is completed. When automatic parking is finished, the MCU automatically recognizes the change of the working state and detects the existence of the torque margin at the same time, the MCU is switched to the slow torque response slope, the torque margin is discharged at the slow response slope, the torque impact phenomenon is greatly improved, and therefore the driving comfort of the whole vehicle is improved. 本发明实施方式提供一种扭矩余量泄放的电机驱动控制方法、系统及存储介质，属于汽车领域，包括：VCU接收泊车指令，请求速度环工作模式和目标转速；MCU执行速度环工作模式；根据目标转速进行PI调节，输出执行扭矩；完成泊车。本发明自动泊车结束时，MCU自主识别工作状态转变的同时检测到扭矩
