摘要
大型车辆相对于小型乘用汽车,在驾驶中存在更大的视觉盲区。针对这一问题,基于"蝇眼"传感原理和CAN总线原理,将主控节点和多组超声测距节点进行组网,构建了"蝇眼"传感网络,并将"蝇眼"传感网络应用到重型车辆防撞系统中。以8位嵌入式微控器为核心,完成了系统的软硬件设计。该系统实现了大型车辆盲区覆盖探测,并实时地显示障碍物方位和距离,提高了车辆的主动安全性能。
Large vehicle has a big visual blind spot compared to small passenger automobile. To solve this problem, ＂fly＇s eye＂ network built up of one master node and many ranging nodes was made, which was applied to large vehicle anti-collision system. Software and hardware of system were designed based on 8-bit embedded microcontroller. The system realized detection coverage for blind spots of a large vehicle, plus, displays the direction and distance in real-time, so that it could improve active safety features of large vehicles.
