The invention discloses an unmanned driving safe vehicle following distance calculation method. The method comprises the following steps: step 1, data acquisition; 2, data preprocessing; 3, data fusion: fusing the information of the distance d and the speed v of the vehicle after data preprocessing in the step 2 with the humidity h, the temperature t and the rainfall intensity r sensed by the environment sensing sensor group to obtain comprehensive data; 4, determining to select a first algorithm model or a second algorithm model according to the numerical range of the comprehensive data; and 5, determining a safe car following distance. According to the invention, by integrating multi-source sensors such as the vehicle-mounted radar sensor and the environment sensing sensor group, all-around real-time monitoring of surrounding vehicles and environment conditions is realized. According to the characteristic, the scheme can accurately sense and dynamically adjust the vehicle following distance in a complex and changeable traffic environment, especially under the condition of severe weather, so that traffic accidents such as rear-end collision and the like are effectively prevented, and the safety performance of the unmanned vehicle is greatly improved.

    本发明公开了一种无人驾驶安全跟车距离计算方法,包括:步骤1:数据采集;步骤2:数据预处理;步骤3:数据融合,将步骤2数据预处理后的车辆的距离d和速度v信息,与环境感知传感器组感知到的湿度h、温度t、降雨强度r进行融合,获得综合数据;步骤4:根据综合数据的数值范围,确定选用第一算法模型或第二算法模型;步骤5:确定安全跟车距离。本发明通过集成车载雷达传感器、环境感知传感器组等多源传感器,实现了对周围车辆及环境条件的全方位实时监测。这一特性使得方案能够在复杂多变的交通环境中,特别是在恶劣天气条件下,准确感知并动态调整跟车距离,从而有效预防追尾等交通事故的发生,极大地提升了无人驾驶车辆的安全性能。
