为了能有效准确地根据事故现场情况预测出碰撞前车辆的运行车速情况,文章利用反推算法,遵循相关物理定律,构建正面碰撞事故中车辆相关参数及道路条件与车速的函数关系,并基于Visual Basic平台搭建车速预测模型并进行实测验证。结果表明,所构建模型的误差率较低,所构建模型、系统是正确高效的,可用于正面碰撞事故的车速预测研究工作。

Reconstruction simulation of vehicle frontal collision accidents

In order to effectively and accurately predict vehicle running speed before collision according to the scene of the accident, by virtual of back stepping, this paper follow the principle of Physics, constructed the function between vehicle frontal collision related parameters, the road conditions and vehicle speed. Based on the Visual Basic, we have set up speed prediction model and testified in practice. The results show that, the error of constructed model rate is low, the model and system is correct and efficient, which can be used to predict the speed of frontal collision accident research
