摘　　要：在人车事故碰撞过程中,计算车辆的碰撞速度是其中的重要环节。速度计算通常是通过制动距离、监控视频、行车记录仪等一些线索得出,但在一些比较特殊的环境中这些方法就不太适用。注意到碰撞后路面痕迹及人-车最终距离是可测的,利用理论模型与Matlab分析,通过人-车最终距离计算碰撞车速,并对其进行定量分析。结果显示:采用该方法计算得出的车辆行驶速度误差值可控制在5%以内。In vehicle-collision accidents,the calculation speed of collision of a vehicle is one of the important issues. The speed calculation is usually derived from the surveillance video,tachograph and some other intuitive clues. But in some special circumstances,such as vehicle-pedestrian accidents,these methods do not suit for the vehicle collision speed calculation,However,due to the fact that the post-collision trail and the final distance between the vehicle and the pedestrian are measurable,the vehicle speed can be estimated by the final vehicle-pedestrian distance through the theoretical model and the Matlab analysis,besides,the quantitative analysis is also carried out,the vehicle speed error calculated by this method can be controlled within 5%.
