Abstract

Vehicle-to-everything (V2X) communication is an essential technology for autonomous driving above Level 4. This paper presents preview control of automotive actives suspension systems to improve ride comfort using vehicle-to-vehicle (V2V) communication. Generally, while preview-controlled active suspension systems have even greater potential than feedback-controlled systems, their main challenge is obtaining preview information of the road profile ahead. A critical drawback of the “look-ahead” sensors is an increased risk of incorrect detection influenced by water, snow, and other soft obstacles on the road. In this work, a preview control algorithm for active suspension systems has been developed without information about the road elevation. The proposed controller is designed with the future disturbance information, vertical wheel acceleration transmitted from preceding vehicle via V2V communication. For active suspension control, an optimal preview controller is designed with the reduced linear half-car model. The performance of the proposed controller has been validated via computer simulation studies. It is shown that the vehicle ride comfort can be improved by the proposed preview control approach more than by the feedback method.
汽车主动悬架系统的预览控制,利用V2V通信改善乘坐舒适性
车联网(V2X)通信是实现4级以上自动驾驶的必要技术。本文介绍了利用车对车(V2V)通信的汽车主动悬架系统的预览控制,以提高乘坐舒适性。一般来说,虽然预控主动悬架系统比反馈控制系统具有更大的潜力,但它们面临的主要挑战是获取前方道路轮廓的预控信息。“前瞻”传感器的一个关键缺点是受水、雪和道路上其他软障碍物的影响,错误检测的风险增加。在这项工作中,开发了一种不需要路面高程信息的主动悬架系统预览控制算法。该控制器利用前车通过V2V通信传输的未来扰动信息、车轮垂直加速度信息进行设计。针对主动悬架控制,采用简化的线性半车模型设计了最优预瞄控制器。通过计算机仿真研究验证了所提控制器的性能。结果表明,与反馈控制相比,该方法能更好地改善车辆的平顺性。
