汽车防碰撞预警系统的研究

随着汽车工业的迅猛发展,汽车保有量逐年增加。汽车不仅给人们的生活带来方便,同时由于汽车引发的事故也越来越多。这些交通事故主要是车辆和车辆的碰撞、车辆和行人的碰撞。大量研究数据表明,交通事故的引发主要由于驾驶员驾驶过程中疲劳,从而引起注意力转移,导致汽车出现追尾或不按正常的道路路线行驶。研究表明,在引发的各类交通事故中,如果在出现事故前1秒钟,驾驶员能够及时采取制动措施,就能减少80%以上的交通事故。为此,论文研究了汽车防碰撞预警执行系统,该系统是基于超声波测距,以单片机为CPU。在车辆行驶的过程中,不断检测和计算汽车前方或后方行人、车辆或建筑物的距离,通过将传感器采集到的实时数据传送CPU,当结果显示前方或后方距离接近制动车距时,系统便向蜂鸣器发出报警信号,促使驾驶员及时采取措施,防止交通事故发生。该系统可以降低交通事故发生率,从而提高汽车行驶的安全性。

With the rapid development of automobile industry, car ownership increases year by year. They not only bring convenience to people's life, also bring more and more accidents. The traffic accident is mainly collision of vehicle and vehicle, collision of vehicle and pedestrian. A large amount of research data show that traffic accidents mainly due to fatigue driving. Leading to attention, car crash or not drive on the normal road route. The research shows that all kinds of traffics can reduce 80% if the driver brake in 1 second before an accident. The paper studies the vehicle collision warning execution system based on microcontrollers. the system tests and calculates the distance of people, car and structure in the process of vehicle.The sensors collect real-time data and transmit to CPU. When the results show that the front or rear distance closer to the braking distance. System will send alarm signal to buzzer and the driver brake the vehicle traffic accidents wil be prevented. The system can reduce the incidence of traffic accidents and improve the safety of the car.
