The invention belongs to the technical field of unmanned driving safety control methods and relates to a control method for protecting a rear automobile during emergency braking of an unmanned automobile. According to the method, an environment identification module of the unmanned automobile monitors the speed V1 of the automobile, the speed V2 of the rear vehicle and the distance S1-2 between the rear automobile and the automobile; the minimum emergency braking safety distance S00 between the rear automobile and the automobile is calculated according to the automobile speed V2 of the rear automobile; the S00 is properly adjusted according to the S1-2; and during emergency braking, the acceleration value of emergency braking of the automobile is controlled according to the S1-2 and the S1-0, so that the braking response time of a driver of the rear automobile is prolonged, the probability of rear-end collision between the rear automobile and the automobile is reduced, and the safety of emergency braking of the automobile is improved, and the driving safety of the rear automobile is greatly improved.

    本发明涉及无人驾驶安全控制方法技术领域,具体涉及无人驾驶汽车紧急制动时保护后方车辆的控制方法,无人驾驶汽车的环境识别模块监测本车车速V1、后车车速V2以及后车与本车之间距离S1‑2,根据后车车速V2计算出后车与本车之间最小紧急制动安全距离S00,根据S1‑2的大小适当调整S00的大小,紧急制动时,根据S1‑2的大小以及S1‑0的大小控制本车紧急制动的加速度值大小,以增加后车驾驶员的制动反应时间,减小后车追尾本车的概率,极大的提高后车的行车安全性。
