The invention is suitable for the technical field of vehicle control, and particularly relates to a vehicle braking distance control method and system based on parking sight distance, and the method comprises the steps: obtaining traffic scene data, and constructing a heterogeneous traffic following scene model; performing reaction time calibration through traffic flow simulation, wherein the step of performing the reaction time calibration comprises data acquisition and processing and cross-correlation result analysis; calculating the reaction distance and the braking distance of the automatic driving vehicle under the heterogeneous flow; and the vehicle is controlled based on the reaction distance and the braking distance of the autonomous vehicle, so that the autonomous vehicle and the leading vehicle keep a corresponding safe braking distance. According to the method, the vehicle parking sight distance can be calibrated in a traffic flow simulation mode, the braking distance is determined, the automatic driving vehicle and the front vehicle are controlled to always keep the safe parking distance through the control system, and due to the fact that the parking sight distance is reduced and the distance between the vehicles is reduced, the traffic efficiency can be greatly improved under the condition that the traffic safety is guaranteed.

    本发明适用于车辆控制技术领域,尤其涉及基于停车视距的车辆制动间距控制方法及系统,所述方法包括:获取交通场景数据,构建异质交通跟驰场景模型;通过交通流仿真进行反应时间标定,所述进行反应时间标定的步骤包括进行数据采集和处理以及互相关结果分析;计算反应距离和异质流下自动驾驶车辆的制动距离;基于反应距离和自动驾驶车辆的制动距离对车辆进行控制,使得自动驾驶车辆与前导车保持相应的安全制动间距。本发明能够通过交通流仿真的方式对车辆停车视距进行标定,并确定制动间距,通过控制系统控制自动驾驶车辆与前车始终保持安全停车距离,由于停车视距减小,车辆之间的间距减小,能够在保证交通安全的情况下较大的提高交通效率。
