The invention discloses an automobile rear-end collision prevention early warning method and system.The system comprises an automobile braking mathematical model unit, a safety distance early warning unit, a safety belt pre-tightening unit and a safety air bag ignition unit, and the automobile braking mathematical model unit judges whether a dangerous condition exists or not according to a mathematical expression of the theoretical braking distance of two automobiles; the safety distance early warning unit gives out danger avoiding reminding to a driver under the dangerous condition, the safety belt pre-tightening unit improves the restraining force on a safety belt under the dangerous condition, and the safety air bag ignition unit is ignited in advance under the dangerous condition. The scheme has the advantages of being clear in analysis and high in reliability, early warning of different levels can be given out to drivers and passengers according to different dangerous conditions, restraining force of different strengths can be generated on the safety belt, the practicability is higher, the safety air bag can be ignited in advance, the protection performance is higher, and the safety air bag is arranged on the rear bumper and can protect a vehicle body.

    本发明公开了一种汽车防追尾预警方法及系统,该系统包括汽车制动数学模型单元、安全距离预警单元、安全带预紧单元以及安全气囊点爆单元,汽车制动数学模型单元根据两车理论刹停距离的数学表达式判断是否存在危险状况,安全距离预警单元在危险状况下对驾驶员发出避险提醒,安全带预紧单元在危险状况下提高对安全带的约束力,安全气囊点爆单元在危险状况下提前点爆;本方案具有分析明确、可靠性高的优点,可根据不同危险状况对驾乘人员发出不同等级的预警以及对安全带产生不同强度的约束力,实用性能更强,安全气囊可提前点爆,防护性能更高,安全气囊设置在后保险杆上,可对车身进行保护。
