【摘要】：现代交通运输业的快速发展,使人们的出行方式发生了很大的改变,居民汽车拥有量逐年增长。随着汽车拥有量的迅猛增长,道路也因为车流量以及车流密度的增加而越来越拥堵,随之而来的车辆追尾碰撞事故日渐突出。汽车在给人们带来方便和快捷的同时,也威胁着人们的生命和财产安全。同时,交通事故处理的公正性和公平性也考验着相关部门。大多数的追尾事故,两车并不是对心碰撞,在事故发生之后,现场留下的车辆轨迹比较复杂,两车并不是做一维运动,因此亟需新的方法对偏置追尾事故进行分析。本文在实际追尾事故案例的基础上,根据追尾事故的特点,从驾驶人、车辆、道路和环境角度分析了追尾事故发生的原因。建立了4种典型的追尾事故碰撞类型,利用仿真软件PC-Crash,分别对不同相对速度、不同偏置度下的4种碰撞类型进行仿真分析。分别对四种追尾碰撞类型中驾驶人制动和转向两种操作行为下,车辆的运动行为进行了仿真,获得追尾事故中车辆运动参数。以偏置度、相对速度等作为自变量,速度、加速度、角速度等运动学参数作为因变量,通过软件仿真模拟,系统分析自变量与车辆运动行为间的关系。同时根据再现结果的不确定性,改变参数数据,输入仿真参数,分析车辆运动行为的变化特征。研究结果将为驾驶人的行为决策、事故再现以及车辆的安全设计提供理论依据。
[Abstract]:With the rapid development of modern transportation industry, people's travel mode has changed greatly, and the number of car ownership has increased year by year, with the rapid growth of vehicle ownership. Because of the increase of traffic flow and traffic density, the road becomes more and more congested, and the vehicle collision accident becomes more and more prominent. The vehicle brings convenience and speed to people at the same time. At the same time, the fairness and fairness of traffic accident handling is also testing the relevant departments. Most of the rear-end accidents, two cars are not to the heart of the collision, after the accident. The track of the vehicle left on the scene is more complex, the two vehicles do not do one-dimensional movement, so it is urgent to use a new method to analyze the bias rear-end accident. This paper is based on the actual case of the rear-end accident. According to the characteristics of the rear-end accident, the causes of the rear-end accident are analyzed from the point of view of the driver, vehicle, road and environment. Four typical collision types of the rear-end accident are established, and the simulation software PC-Crash is used. Four collision types with different relative velocities and different bias degrees were simulated and analyzed respectively. The motion behavior of the vehicle is simulated to obtain the vehicle motion parameters in the rear-end accident, such as bias, relative velocity as independent variables, velocity, acceleration, angular velocity and other kinematics parameters as dependent variables. Through the software simulation, the relationship between independent variables and vehicle motion behavior is analyzed systematically. At the same time, according to the uncertainty of the reappearance result, the parameter data is changed, and the simulation parameters are input. The research results will provide theoretical basis for driver's behavior decision, accident reappearance and vehicle safety design.
