摘要
为研究轮毂电机在不同控制策略下对整车的操纵稳定性的影响,充分发挥轮毂电机汽车的优势,选择三种电机控制策略,基于稳态回转试验、转向盘转角阶跃输入试验和脉冲输入试验,得到相应的试验结果。研究发现不同控制策略对整车的侧倾稳定性、不足转向特性和整车响应速度等方面具有一定影响。因此需要依据轮毂电机汽车的定位和设计需要选择适应的电机控制策略。
In order to study the influence vehicle controllability and stability with different control strategies for in-wheel motors, and to give full play to the advantages of in-wheel motors, three motor control strategies were selected. The steady-state circular test, steering wheel angle step input test and pulse input test were conducted, and the test results were analyzed. The study found that different control strategies have certain effects on the vehicle’s roll stability, understeer characteristics, and vehicle response. Therefore, it is necessary to select an appropriate motor control strategy according to the positioning and design needs of the in-wheel motor vehicle.
