【摘要】:人-车碰撞事故中通常包含不确定因素,根据这些取值不确定的参数估算车速,具有不准确性。提出一个基于汽车-行人第一落地点的碰撞车速计算模型,可应用于行人抛距不可靠的情况下。为了提高该模型碰撞车速计算的准确性,引入了再现车速不确定度理论的评定方法。结合一起轿车与行人的碰撞事故,计算出行人第一落地点车速模型的车速最优取值范围。通过PC-Crash、MADYMO模拟仿真验证及与抛距模型车速计算结果的对比,验证上述车速计算分析流程的可行性与合理性。
[Abstract]:The uncertain factors are usually included in the man-vehicle collision accident. It is inaccurate to estimate the speed according to these uncertain parameters. A collision speed calculation model based on the first landing place of vehicle and pedestrian is proposed, which can be used in the case of unreliable pedestrian throw distance. In order to improve the accuracy of calculating the collision speed of the model, an evaluation method based on the theory of reproducing the uncertainty of the speed is introduced. Combined with a collision accident between passenger car and pedestrian, the optimal range of vehicle speed is calculated. The feasibility and rationality of the speed calculation and analysis flow are verified by comparing the simulation results of PC-Crash-MADYMO and the speed calculation results of the throw distance model.
