The invention belongs to the technical field of automatic driving, and particularly relates to an automatic emergency collision avoidance control method and device, a storage medium and a vehicle. The method comprises the steps that the distance between a vehicle and a front vehicle, the motion state of the vehicle and the motion state of the front vehicle are obtained; according to the distance between the vehicle and the front vehicle, the motion state of the vehicle and the motion state of the front vehicle, whether the minimum collision time ttc of the vehicle and the front vehicle is smaller than preset time or not is judged, and if it is judged that the minimum collision time ttc of the vehicle and the front vehicle is smaller than the preset time, whether the vehicle will collide with the front vehicle or not is judged; and when it is judged that the vehicle will collide with the front vehicle, the vehicle is controlled to execute an emergency collision avoidance strategy. The method aims to adopt corresponding emergency collision avoidance measures by judging the collision risk of the vehicle and the front vehicle, the situation that the vehicle is subjected to rear-end collision by the rear vehicle after speed reduction and whether the adjacent lane has a lane change suppression target or not, so that the driving safety under the limiting working condition is improved, and the threat to life and property safety is reduced to the maximum extent.
本发明属于自动驾驶技术领域,具体涉及一种自动紧急避撞的控制方法、装置、存储介质及车辆。该方法包括,获取本车与前车的距离、本车运动状态和前车运动状态;根据所述本车与前车的距离、本车运动状态和前车运动状态,判断本车与前车的最小碰撞时间ttc是否小于预设时间,若判断所述本车与前车的最小碰撞时间ttc小于预设时间,判断本车与前车是否会发生碰撞;当判断所述本车与前车会发生碰撞,控制本车执行紧急避撞策略。其目的是:能够通过判断本车与前车的碰撞风险、本车减速后被后车追尾的情况以及相邻车道是否存在抑制变道目标,采取相应的紧急避撞措施,提高极限工况下的行驶安全性,最大程度减小对生命财产安全威胁。
