The invention discloses an automobile rear-end collision early warning system which comprises a data acquisition module, a data calculation processing module and a voice broadcast module. The data acquisition module is mounted at the front/tail part of an automobile and is used for acquiring motion data of front/rear automobiles; the data calculation processing module is used for calculating the collected motion data of the front/rear vehicles and the motion data of the current vehicle to obtain time T required for rear-end collision between the front/rear vehicles and the current vehicle; the time required for rear-end collision and calculated by the data calculation module is compared with the time built in the system, and the early warning module connected with the data calculation module sends out a corresponding risk early warning level signal. The beneficial effects of the invention are that the data acquisition module acquires the motion data of the front/rear vehicles, and the data information of the front/rear vehicles is combined with the motion data of the current vehicle to calculate the time required for the rear-end collision of the front/rear vehicles through the data calculation module.

    本发明公开了一种汽车追尾预警系统,包括数据采集模块、数据计算处理模块和语音播报模块;所述数据采集模块安装在汽车前/尾部用于采集前/后方车辆的运动数据;所述数据计算处理模块将采集得到的前/后方车辆的运动数据和当前车辆的运动数据进行计算得出二者之间的发生追尾所需要的时间T;所述数据计算模块计算得出的发生追尾所需的时间与系统内置的时间对比,与数据计算模块连接的预警模块发出相应的风险预警等级信号。本发明的有益效果是:通过数据采集模块对前/后方车辆的运动数据进行采集,前/后车辆的数据信息结合当前车辆的运动数据通过数据计算模块进行计算出二者发生追尾所需要的时间。
