The invention discloses an automatic emergency braking method, device and system for a vehicle and a readable storage medium, and the braking method comprises the steps that the emergency braking stage number of the vehicle is determined, and the emergency braking stage number of the vehicle comprises multiple stages; the braking deceleration of each stage is obtained according to the emergency braking stage number of the vehicle; acquiring surrounding environment information of the vehicle, and acquiring a relative distance and a relative speed between the vehicle and an effective obstacle when the effective obstacle is determined according to the surrounding environment information; the braking distance of each stage is calculated according to the relative speed and the braking deceleration of each stage, then the current emergency braking stage number of the vehicle is determined according to the relative distance and the braking distance of each stage, and finally the vehicle is controlled to conduct emergency braking according to the current emergency braking stage number of the vehicle. Therefore, according to the automatic emergency braking method for the vehicle, the vehicle can be better braked by fully utilizing the braking characteristics of the vehicle, the braking effect of the vehicle is improved, and meanwhile the driving safety and the user experience are improved.

    本发明公开了一种车辆自动紧急制动方法、装置和系统、可读存储介质,其中,制动方法包括:确定车辆的紧急制动级数,其中,车辆的紧急制动级数包括多级;根据车辆的紧急制动级数获取每级制动减速度;获取车辆的周围环境信息,并根据该周围环境信息确定出有效障碍物时获取车辆与有效障碍物之间的相对距离和相对速度;根据该相对速度和每级制动减速度计算每级制动距离,再根据相对距离和每级制动距离确定车辆当前进行紧急制动的级数,最后根据车辆当前进行紧急制动的级数控制车辆进行紧急制动。由此,该车辆自动紧急制动方法能够充分利用车辆的制动特性更好的制动车辆,提高车辆的制动效果,同时提高行车安全性和用户体验。
