摘　　要：本文分析了超声波测距原理,并基于超声波测距原理设计了超声波泊车辅助系统,该系统由6个超声波模块组成的超声波探测网络、CPU模块、温度检测模块、显示模块、报警模块等组成。在泊车过程中,系统对车体与前后障碍物之间的距离进行全面测量,测量值送液晶屏实时显示,并在距离值过小时给出报警文字提示及不同频率的声音报警信号。经多次测试,并与实际距离值对比,系统测量误差约1cm,满足使用要求,能有效降低泊车过程中的碰撞事故,缩短泊车时间。This paper analyzed the principle of ultrasonic ranging,and designed an ultrasonic parking assist system based on the principle of ultrasonic ranging.The system consists of an ultrasonic probe network composed of 6 ultrasonic modules,a CPU module,a temperature probe module,a display module and an alarm module.The system comprehensively measured the distance between the car body and the front or rear obstacles during parking.The measured values are sent to the LCD screen for real-time display,when the distance value is too small,it will give an alarm text prompt and a different frequency sound alarm signal.After many tests and compared with the actual distance value,the measurement error of the system is about 1cm,which meets the requirements for use.It can effectively reduce collision accidents during parking and shorten the parking time.
