摘　　要：针对汽车追尾事故带来的严重危害,设计了一种汽车智能防追尾控制系统。该系统利用角度传感技术、双目视觉测距及毫米波雷达测距技术对弯道和直道分别进行测距测速,并根据安全距离数学模型推算结果,运用模糊算法对汽车进行速度控制,从而有效地防止追尾的发生。最后通过Matlab的仿真结果证明了控制过程的正确性。该系统还利用Zigbee通信技术对高速和城市运行2种模式进行切换,从而提高了系统应用的灵活性和可靠性。For relieving the harms caused by rear-end accident,an intelligent automobile control system against rear-end colli-sion is developed. Angle sensor technology, binocular vision range and millimeter wave radar ranging technology are integrated in the system and applied for distance and velocity measurement on crowed roads and straight roads separately. In order to avoid automobile rear end collision, the results are calculated according to the mathematical model for safe distance and the speed is controlled by using tuzzy control algorithm. Then through the Matlab simulation results the validity of the control process is verified. In addition, Zigbee comnmnication technology is used for the switch between high - speed operation mode and re＇ban operation mode, thus the flexibility and reliability of the system are greatly improved.
