摘要
基于超声波原理设计了汽车盲点辅助预警系统测距模块。应用Altium Designer软件设计了超声波传感器发射和接收电路,应用Code Warrior平台中PE工具设计测距模块的控制策略。实验结果表明:试验测得的超声波探头至障碍物的距离与用卷尺量得的实际距离相近,并且在减小探头与障碍物之间距离的过程中发射和接收信号的时间间隔随之减小,所设计的硬件和软件符合要求。
Based on the principle of ultrasonic, the distance measurement module of auto blind spot as-sist system was designed. The transmitting and receiving circuit of ultrasonic sensor was designed by Al-tium Designer, and control strategy of the distance measurement module was designed by the PE toolsin Code Warrior. The experimental results show that the distance between ultrasonic probe and obstacleobtained by test measurement is similar to the actual distance measured by the tape, and the time inter-val between the transmitting signal and receiving signal reduces as the distance between the probe andobstacle reduces. Therefore, the hardware and software design meets the requirements.
