摘　　要：根据驱动电机系统在纯电动轿车中的应用特性,在复杂工况下,对整车行驶过程中的转矩需求值、速度变化值等参数进行分析,基于模糊控制算法思想,模拟道路路况和驾驶员意愿,线性化调节扭矩补偿值,有效抑制车辆的低速抖动,提高车辆的行驶平稳性。According to the application characteristics of the drive motor system in electric vehicles,under the complicated working conditions,the parameters such as the torque demand value and the speed change value of the vehicle which is working are analyzed,and linearization adjusts the torque compensation value by simulating the road condition and the willingness of driver based on the idea of fuzzy control algorithm,effectively suppresses the shake of the vehicle in low speed,and improves the stability of the vehicle.

关 键 词：驱动电机系统 模糊控制 低速抖动 平稳性
