摘　　要：为解决行驶车辆的防追尾问题、提高行车安全性,设计了一种新型智能车辆安全车速辅助测控系统;基于超声测距技术完成了车距和相对车速的测算,基于模糊控制技术设计了车速的辅助控制器,控制步进电机调节油门节气门的开度,从而实现车速的自动辅助调节;基于嵌入式系统开发技术完成了系统软硬件研发;测试结果表明,系统平均控制精度高达97.6%,平均反应时间仅为527ms;系统能够显著提高行车安全性、有效较低追尾事故发生率,具有较高的实用推广价值。In order to solve the problem of preventing rearend collision of vehicles and improve the driving safety, a new type of intelli gent vehicle safety driving speed control system is proposed in this paper. Measurement of ultrasonic ranging technology is used to complete the distance and relative speed based on the speed controller, the aided design fuzzy control technique based on the stepper motor control, o pening of throttle solar term door, so as to realize the automatic auxiliary speed regulation; embedded system development technology com pleted the system hardware and software R ＆ D. The testing results show that the average control accuracy is up to 97. 6%, the average re sponse time is only 527ms. The system can significantly improve the traffic safety, effective and low accident rate, it has high practical val
