摘要
设计了基于温度补偿的超声波倒车测距系统。该系统通过温度补偿方法解决了环境温度对超声波传播速度的影响,提高了系统的测量精度,并能显示、语音播报车后与障碍物之间的距离,让司机能够视听结合,更加体现人性化。
This paper designs a set of temperature compensation based on reversing ultrasonic ranging system.The system temperature compensation solutions to the impact of the environmental temperature on the ultrasonic propagation velocity,enhancing the system＇s measurement accuracy,and real-time display and voice broadcast from the rear of obstacles,so that drivers audio-visual integration,and more humane.
