摘要
在高速公路上,尤其是在能见度较低的情况下,如何避免汽车追尾碰撞是个亟待解决的问题.在建立汽车安全距离数学模型的基础上,设计了以单片机为核心的红外线防碰撞控制器,当车距小于安全距离时,该控制器发出警告,并在紧急情况下执行制动.
It is an urgent problem how to prevent back car from collide with front one on highways, particularly, in a condition of too weak visibility. On the basis of the mathematics modeling, this paper designs an infrared automatic control system based on single-chip processor, which can send warnings when car space is smaller than the safe distance between cars and implement braking in an emergency.
