重型商用车编队行驶设计运行条件分析

Research on Operational Design Condition of Heavy Commercial Vehicle Platooning Drive

编队行驶是指两辆及以上的车辆,利用通信技术和自动驾驶技术使彼此之间保持一定的车距并以稳定的速度进行行驶。近年来随着无线通信技术和自动驾驶技术的快速发展,重型商用车编队行驶成为重点研究的方向,它有助于提高运输的安全性、效率,同时可以降低能源消耗和尾气排放。设计运行条件(ODC)是编队行驶系统的必备条件,即系统可以启动、安全执行动态驾驶任务的条件。文章通过分析国际上关于设计运行条件的构建方法研究现状,结合编队行驶系统的功能特点,提出了适用于重型商用车编队行驶的设计运行条件,并对动静态实体、环境、驾乘人员、车辆状态、跟车距离做了分析,用于保障编队行驶功能在设计运行范围(ODD)内的稳定运行,有助于提升系统安全。

Platooning drive refers to two or more vehicles using communication technology and autono-mous driving technology to maintain a certain distance and travel at a stable speed.In recent years,with the rapid development of wireless communication technology and autonomous driving technology,the research into heavy commercial vehicle platooning has become a key research direction.It can help improve the safety and efficiency of transportation,and at the same time,can reduce energy consumption and exhaust emissions.Operational design condition(ODC)are necessary prerequisites for platooning system,which means the conditions under which the system can start and safely perform dynamic driving tasks.This article analyzes the current research status of construction methods for design operating conditions internationally,and combines the functional characteristics of platooning systems to propose design operating conditions suitable for heavy commercial vehicle platooning.It also analyzes the dynamic and static entities,environment,driversand passengers,vehicle status,and following distance to ensure the stable operation of platooningfunctions within the operational design domain(ODD),which helps to improve system safety.
