摘　　要：为有效避免雨雾等不良天气和司机驾驶疲劳等情况下的车辆追尾事故,分析前后车安全行驶距离,构建超声波测距模型,利用Proteus仿真软件设计一款防追尾报警装置,包括超声波测速测距模块及行车警示模块,并通过模拟仿真对正常驾驶状态、预警状态以及紧急制动状态下防追尾报警装置进行对比分析.结果表明:本设计相比于普通警示装置,能更加精准地对前后车进行测距,能够有效地降低车辆追尾风险.In order to effectively avoid vehicle rear-end collision accidents under rain,fog or other bad weather conditions,safety distances between front and rear vehicles under such conditions were analyzed,and an ultrasonic ranging model was built.Proteus simulation software was used to design circuits of ultrasonic speed measurement and ranging module and driving warning module,and the normal driving state was simulated.The comparative analysis of the anti-rear-end collision device in early warning state and emergency braking state shows that compared with ordinary warning devices,this design can be applied for more accurate distancing of front and rear vehicles,thus reducing risks of vehicle rear-end collisions in rainy or foggy weather.
