| Abstract: | Focusing on the problems of lower sensitivity and longer dead zone of reversing aid system, a new method named dynamic adjustment of driving pulse number was presented to extend the detectable range of ultrasonic sensors, based on the analysis of the composition and principle of reversing aid system. The interferences that may influence the reversing aid system were analyzed, and the solving means were offered. The analysis of abnormal is given, and abnormal handling flow was introduced in detail. The experiment result shows that the system is of good anti-interference and stability. |
