摘要
为研究电动自行车在道路行驶中的安全性,从人-车-路闭环系统出发,较为全面地分析了电动自行车交通行驶安全性的影响因子。通过分析电动自行车骑行者的主要损伤机理,确定人-车-路闭环系统中影响电动自行车安全性权重较高的因素为运动速度、车辆类型、路面类型和路面状态等。采用实车牵引试验方案,在保证试验安全性的同时,通过正交设计对主要影响因子进行多变量综合试验,系统地分析了电动自行车在道路行驶中的不安全性机理;同时通过大量试验数据建立了倒地电动自行车在各种路面条件下的摩擦因数数据库。结果表明:对电动自行车安全性影响最为显著的因子为运动速度、车辆运动状态、车辆类型、道路类型和道路条件,且运动速度对其安全性的影响最大。
To study road safety of electric bicycles, based on the closed-loop system of driver- vehicle-road, the authors made a comprehensive analysis of the affecting factors for the driving safety of electric bicycles. Through analyzing the main damage mechanism of the electric bicycle users, the speed, vehicle type, road type and road status were determined to be the higher electric bicycle safety weight factors in the closed-loop system of driver-vehicle-road. The program of vehicle traction test was developed with the test security ensured. A multivariate test on the main influential factors was conducted with orthogonal design. Systematic analysis of the insecurity mechanism of electric bicycles on road was made. Based on a large amount of experimental data, a friction coefficient database of overturned electric bicycles in a variety of road conditions was established. The result show that the most significant impact factors on safety of the electric bicycles were velocity, vehicle motion, vehicle type, road type and road condition, and the velocity was the greatest factor on safety.
