The invention discloses an automatic driving vehicle rear-end anti-collision control method and system, a computer and a storage medium. The method comprises the steps: S1, collecting vehicle information of an automatic driving vehicle and an adjacent rear vehicle on a current lane of the automatic driving vehicle, and calculating critical response time based on the vehicle information; and S2, calculating a collision probability of the current rear vehicle and the automatic driving vehicle based on the critical response time, if the collision probability is higher than a preset threshold value, making the automatic driving vehicle be in a rear-end anti-collision control mode, and otherwise, making the automatic driving vehicle be in an original control mode of automatic driving. Through the control method, a rear-end collision risk caused by distraction, misoperation and the like of a driver of a manual driving vehicle under the condition of mixed flow of manual driving and automaticdriving in an automatic driving development transition stage is effectively reduced, and expressway traffic safety in the automatic driving development transition stage is effectively improved.
本发明公开了一种自动驾驶车后端防撞控制方法、系统、计算机、存储介质,其中,该控制方法包括:S1:采集自动驾驶车辆以及所述自动驾驶车辆当前车道上相邻后车的车辆信息,并基于车辆信息计算出临界反应时间;S2:基于所述临界反应时间计算出当前所述后车与所述自动驾驶车辆的碰撞概率,若所述碰撞概率高于预设阈值,控制所述自动驾驶车辆处于后端防撞控制模式,否则,控制所述自动驾驶车辆处于自动驾驶的原始控制模式。本发明通过上述控制方法有效降低自动驾驶发展过度阶段中人工驾驶与自动驾驶混合流情况下,由于人工驾驶车辆驾驶员分心、操作失误等造成的追尾风险,有效提高自动驾驶发展过渡阶段的高速公路交通安全。
