面向5G远程自动驾驶的CPSS控制系统研究

Study on 5G remote automatic driving vehicle of CPSS control system

自动驾驶技术在提升道路安全、通行效率和降低能耗等方面有着巨大潜力。国内外有不少专家和学者提出了多种自动驾驶系统解决方案,但大部分都还处于宏观系统研究层面,缺少结合具体应用场景的系统化技术解决方案。从信息物理社会(CPSS)系统视角,结合5G通信、远程遥控驾驶、网联自动驾驶等应用技术,提出一种结合新型5G通信网络的自动驾驶系统架构。采用该自动驾驶车辆系统解决方案,将一款具备线控底盘的车辆改造成了自动驾驶车,并搭建了自动驾驶车辆运行环境,开展了通信时延、主动安全性能和自动驾驶控制性能,实车验证试验。结果表明:从CPSS视角提出的5G远程自动驾驶系统解决方案,可实现自动驾驶车辆安全、有效控制,具备商业化推广的技术可行性。

Automatic driving technology has great potential in improving road safety,traffic efficiency and reducing energy consumption.At present,there are some researches on solutions of automatic driving control system,but most of them are still in the level of macro system research,and lack of technical system solutions combined with specific application scenarios.From the perspectiveof Cyber-Physical-Social Systems(CPSS),combined with 5G communication,remote control driving and network automatic driving technology,this paper proposes a new automatic driving system architecture combining with the new 5G communication network.Based on the solution of the automatic driving vehicle system,a vehicle with wire chassis is transformed into an automatic driving vehicle,and the operation environment of the automatic driving vehicle is built.Moreover,the real vehicle verification tests of communication delay,basic auxiliary safety performance and automatic driving control performance are carried out.The results show that the 5G remote automatic driving system solution from the perspective of CPSS can achieve the safety and effective control of the automatic driving vehicle,and has the technical feasibility of commercial promotion.
