摘要
全线控分布式驱动电动汽车底盘协同控制能够有效提高车辆的安全性与乘坐舒适性。以整车安全性与乘坐舒适性为目标,围绕车辆操纵稳定性控制、底盘容错控制、车身姿态控制与车辆平顺性控制四个方面,全面综述全线控分布式驱动电动汽车底盘协同控制关键技术与研究进展。针对操纵稳定性,介绍了驱动防滑与制动防抱死等车辆纵向稳定性控制方法,系统对比分析了单线控子系统和多线控子系统在车辆横摆与侧倾稳定性控制上的优缺点;概述分布式电驱动系统和线控转向系统失效时的底盘容错控制方法,详细讨论利用底盘协同控制降低线控子系统失效影响的可行性及主要控制方法;总结利用单/多线控子系统进行车身俯仰姿态与平顺性控制的方法,指出应兼顾车身姿态与平顺性控制,以提高车辆乘坐舒适性控制方法在复杂行驶工况下的有效性;最后,展望全线控分布式驱动电动汽车底盘协同控制技术发展趋势。
Chassis coordinated control for full X-by-wire distributed-drive electric vehicles can effectively enhance both safety and ride comfort during vehicular operation.Taking vehicle safety and ride comfort as objectives,this paper provides a comprehensive review of key technologies and challenges in the chassis coordinated control for full X-by-wire distributed-drive electric vehicles,encompassing handling stability control,fault-tolerant control,vehicle attitude control,and ride comfort control.For handling stability control,traction control and anti-lock braking methods are introduced.A systematic analysis is conducted to evaluate the advantages and disadvantages of using one single or multiple X-by-wire subsystems in lateral and roll vehicle stability control.Regarding fault-tolerance control,the paper outlines fault-tolerant control strategies that use direct yaw-moment control to complement steer-by-wire systems.The paper summarizes methods for pitch attitude control and ride comfort control using one single or multiple X-by-wire subsystems.It emphasizes the importance of simultaneously addressing vehicle attitude and ride comfort to enhance control adaptability in complex operating conditions.Finally,the paper provides insights into future directions in chassis coordinated control.
