The invention discloses a vehicle rear-end collision prevention method and device for an unmanned vehicle, and belongs to the technical field of automatic driving. The method comprises the steps that the minimum braking distance between a vehicle and a rear vehicle is obtained; calculating a safety alarm distance between the vehicle and the rear vehicle according to the minimum braking distance between the vehicle and the rear vehicle; detecting the distance between the vehicle and the rear vehicle; calculating whether the distance between the vehicle and the rear vehicle is smaller than a safety alarm distance; if the distance between the vehicle and the rear vehicle is smaller than the safety alarm distance, the vehicle sends out a sound-light alarm signal to remind the rear vehicle to keep the safety distance, otherwise, the vehicle keeps running normally. The maximum braking deceleration of the vehicle is obtained, then the safety alarm distance is calculated, the alarm signal is sent out based on the relation between the actual distance between the vehicles and the safety alarm distance, the occurrence rate of rear-end collision accidents can be reduced, and the safety of vehicle driving is improved.

    本申请公开了一种用于无人车的车辆防追尾方法和装置,属于自动驾驶技术领域。所述方法包括:获取车辆和后车的最小刹车距离;根据车辆和后车的最小刹车距离计算得出车辆和后车的安全报警距离;检测车辆与后车之间的距离;计算车辆与后车之间的距离是否小于安全报警距离;若车辆与后车之间的距离小于安全报警距离,则车辆发出声光报警信号提醒后车保持安全距离,否则车辆保持正常行驶。本申请获取车辆最大刹车减速度,进而计算得出安全报警距离,基于车辆间的实际距离与安全报警距离的关系发出报警信号,能够降低追尾事故的发生率,提高车辆驾驶的安全性。
