The invention provides a vehicle emergency braking method and device, a vehicle and a storage medium. The vehicle emergency braking method comprises the steps that a target object is sensed based on surrounding environment information of a vehicle; triggering parameters of a braking module are obtained, wherein the triggering parameters comprise an initial collision time threshold value and a collision factor; calculating collision time between the vehicle and the target object according to the relative distance and the relative speed of the vehicle and the target object; when the collision time is smaller than or equal to the product of the initial collision time threshold value and the collision factor, a braking module is triggered to conduct emergency braking; after each emergency braking is finished, judging whether the emergency braking is triggered by mistake or not; and under the condition that the false triggering is judged, the collision factor is progressively decreased and updated. According to the invention, the triggering parameters of the braking module can be optimized, false triggering in the emergency braking process of the vehicle is reduced, the driving safety and comfort are improved, and the user experience is improved.
本发明提供一种车辆紧急制动方法、装置、车辆及存储介质。该车辆紧急制动方法包括:基于车辆的周围环境信息感测目标对象;获取制动模块的触发参数,所述触发参数包括初始碰撞时间阈值以及碰撞因子;根据车辆和目标对象的相对距离和相对速度计算车辆和目标对象之间的碰撞时间;在碰撞时间小于等于初始碰撞时间阈值与碰撞因子的乘积的情况下,触发制动模块进行紧急制动;在每次紧急制动结束后,判断该次紧急制动是否为误触发;以及在判断为误触发的情况下,对碰撞因子进行递减更新。根据本发明,能够优化制动模块的触发参数,减少车辆紧急制动过程中的误触发,提升了驾驶的安全性和舒适度,改善了用户体验。
