| 摘 要： | 针对现有安全状态判别模型未能兼顾行车安全与道路空间资源利用率,且忽略了实际行驶环境下动态制动减速度信息的问题,提出了车路集成条件下车辆防撞预警安全状态判别模型。通过车-路通信协作实现对路面类型等实际行驶环境因素的动态识别,并确定车辆采取制动措施时所能获得的动态制动减速度;通过分析前车与自车的有效制动时间和车辆制动全过程,建立了新型临界跟车距离模型,并给出了模型关键参数的获取方法。仿真结果表明,该判别模型具有较强的自适应性,更贴近车辆实际行驶环境下的制动过程,有利于提高道路空间的利用率。

| Abstract: | In view of the problem that existing safety status identification models did not take account of both driving safety and road-space resource utilization simultaneously and also neglect the dynamic braking deceleration information in real driving environment,a safety status identification model for vehicle collision warning is proposed under vehicle infrastructure integration condition.The dynamic identification of real driving environment factors including road surface conditions is realized by means of veh... |
