近年来随着全球资源、环境问题日益严峻,节能、环保的电动汽车得到快速发展。电动汽车采用电机驱动系统,具有转矩快速响应、易于精确测量、可实现动力分散控制、可实现制动能量回收等优点。充分挖掘并利用这些优点可显著提升车辆动力学控制性能。文中从电动汽车动力学控制运行参数的识别、动力学控制结构与方法两个角度综述了十多年来的研究成果,重点介绍了轮胎-路面接触条件识别方法、驱动防滑控制方法等。对车辆横向动力学控制,包括电子差速控制、直接横摆控制、底盘集成控制等研究现状也做了总结。最后对未来电动车辆动力学控制的发展方向作了几点展望。
In recent years, with the global resource and environmental problems becoming more and more serious, energy-saving and environment-friendly electric vehicles have been rapidly developed. Electric vehicle motor drive system, with fast torque response, easy to accurately measure, dynamic dispersion control can be achieved, the advantages of braking energy recovery. Fully tap and take advantage of these advantages can significantly improve vehicle dynamics control performance. This paper summarizes the research results from more than ten years from two aspects of the identification and dynamic control structure of dynamic control of electric vehicle and the method of dynamic control. It mainly introduces the tire-road contact condition recognition method and the driving anti-skid control method. The research status of vehicle lateral dynamics control, including electronic differential control, direct yaw control and chassis integrated control are also summarized. Finally, the future direction of the development of electric vehicle dynamics control made a few prospects.
