The invention relates to the technical field of automobile driving safety, and discloses an automobile rear-end collision prevention early warning system which comprises the following steps that firstly, parameters such as the relative distance and the relative speed of a front automobile and a rear automobile are measured through related sensors on the automobile; the early warning distance and the dangerous distance between the two vehicles at the moment are solved according to a deduced safety distance formula; after data in the S1 and the S2 are input, the system judges whether the early warning distance is smaller than the relative distance between the two vehicles or not; if so, safety is ensured; if the distance is larger than the early-warning distance, an early-warning module of the system sends out early-warning voice to remind a driver to take corresponding operation; then, whether the dangerous distance is smaller than the relative distance between the two vehicles or not is judged on the basis of S3; by means of the automobile rear-end collision prevention early warning system, the safety distance between the two automobiles can be adjusted in real time according to different driving conditions of the front automobile, and the capacity of adapting to the actual environment is higher.

    本发明涉及汽车行驶安全技术领域,且公开了一种汽车防追尾预警系统,包括以下步骤:首先通过汽车上相关传感器将前后两车的相对距离、相对速度等参数测出来;接着根据推导的安全距离公式求出此时两车之间的预警距离以及危险距离;然后将S1与S2中的数据输入后系统进行判断,预警距离是否小于两车之间的相对距离;若小于则安全;若大于预警距离,则系统的预警模块发出预警语音,提醒驾驶员采取相应操作;然后基于S3再进行判断,危险距离是否小于两车之间的相对距离;通过该汽车防追尾预警系统,两车之间的安全距离将根据前车的行驶情况的不同进行实时调整,适应实际环境的能力更强。
