摘要
分布式驱动电动汽车将电机直接置于轮辋中,在大幅简化车辆底盘结构、提高能量效率的同时,能实现轮毂转矩的精确测量与驱动力矩的快速响应,为改善车辆底盘动力学控制系统的安全稳定性提供了独特的优势,已经逐渐被国际汽车领域研究学者认为是最有发展潜力的电动汽车框架之一。分别从底盘纵向动力学控制、横向动力学控制、集成动力学控制等3方面对分布式驱动电动汽车动力学控制研究进展进行了综述,着重介绍了驱动防滑系统、回馈与防抱死协调制动系统、四轮独立转向系统、直接横摆稳定性控制系统、电子差速系统等电动汽车底盘动力学控制的新兴研究热点,并对分布式驱动电动汽车动力学控制研究未来的发展趋势做了几点展望。
The motors of distributed drive electric vehicle will be placed directly in the rim, which greatly simplify the structure of the vehicle chassis and improve efficiency on energy, moreover, wheel motors can accurately measure hub torque and possess rapid response in the driving torque so as to provide a great convenience for improving security and stability of the vehicle chassis dynamics control systems. This paper reviewed the vehicle chassis dynamics control in term of longitudinal dynamics control, lateral dynamics control and integrated dynamics control, and focused on these emerging hotspots including acceleration slip regulation, regenerative and anti-lock braking system, four wheel steer, direct yaw moment control, electronic differential system in chassis dynamics control for distributed drive electric vehicle, and then made several forecasts about research directions of the distributed drive electric vehicle＇s dynamics control in the future.
