随着科技的日新月异的发展,人们对汽车的安全性能要求越来越高。特别是近年来汽车追尾事故的频繁发生,使人们认识了汽车安全的重要性。在购车时,往往把汽车的安全性作为第一考虑对象。针对这种情况,我们设计了一款用单片机控制的自动刹车系统来降低追尾事故的发生。 With the rapid development of science and technology, people’s requirements for the safety performance of automobiles are getting higher and higher. Especially in recent years, rear-end car accidents occur frequently, so that people understand the importance of car safety. In the car, often the car safety as the first consideration. In response to this situation, we designed a microcontroller-controlled automatic braking system to reduce the occurrence of rear-end accidents.
