The invention provides a vehicle rear-end collision early warning method and device, a computer readable storage medium and electronic equipment, and belongs to the technical field of vehicle control, and the method specifically comprises the following steps: obtaining a first relative speed and a first collision duration corresponding to a first vehicle and a second vehicle within a first preset duration; determining first dynamic critical time based on the first relative speed and first preset information; and if the first relative speed, the first collision duration and the first dynamic critical time meet a first preset condition, generating first early warning information. According to the technical scheme provided by the invention, the first dynamic critical time for determining the generation of the first early warning information is dynamically set according to the first relative speed, so that the first dynamic critical time has real-time performance, the real-time scenes where the first vehicle is located are different, and the first dynamic critical time is different, so that the early warning accuracy can be improved, and the user experience is improved. And the phenomenon of frequent early warning is avoided.
本发明提供了车辆追尾预警方法、装置、计算机可读存储介质及电子设备,属于车辆控制技术领域,具体包括如下步骤:获取第一车辆和第二车辆在第一预设时长内对应的第一相对速度和第一相撞时长;基于所述第一相对速度和第一预设信息,确定第一动态临界时间;若所述第一相对速度、所述第一相撞时长和所述第一动态临界时间符合第一预设条件,则生成第一预警信息。本发明提供的技术方案用于确定生成第一预警信息的第一动态临界时间是根据第一相对速度动态设置的,因此该第一动态临界时间具有实时性,第一车辆所处的实时场景不同,第一动态临界时间不同,从而可以提高预警的准确性,避免出现频繁预警的现象。
