Based on the principle of ultrasonic transit time ranging, this article describes that the microcontroller is used as the core to develop the ultrasonic distance-measurement automobile-reversing radar control system. The system includes both hardware and software parts. The hardware part mainly consist single-chip control circuit, ultrasonic transmitting and receiving circuits, temperature compensation circuit and voice alarm circuit. The software design part of the system was divided into several function modules with modular design method, such as main program module, temperature measurement module, voice alarm module and so on. The main program was responsible for dispatching management all the modules. Experiments show that this system can reach design requirement and has high value and broad application prospects.
