基于STC12C5A60S2的汽车侧向盲区探测系统

Vehicle side blind detection system based on STC12C5A60S2

汽车在转弯时,由于驾驶员要观察的环境因素较多,且较为复杂,再加上后视镜存在盲区等因素,使得车辆在转弯时比正常行驶的情况下更易发生交通事故。为了能够在车辆转弯时及时帮助驾驶员发现车辆两侧的障碍物,提醒驾驶员从而避免交通事故的发生。设计了一套基于STC12C5A60S2和超声波传感器的汽车侧向盲区探测系统,该系统使用多个超声波传感器组合在一起对外界障碍物进行实时监测,及时上传障碍物与车辆之间的相对位置,探测距离可达5m,系统探测精度达到5%。该系统能够发现并提醒驾驶员侧向障碍物与车身的相对位置,对避免交通事故的发生具有重要意义。

When a car is turning,it is more prone to traffic accidents than when it is normally driving due to the many and complex environmental factors that the driver has to observe,as well as the blind spots in the rearview mirror and other factors.In order to help the driver find the obstacles on both sides of the vehicle in time when the vehicle turns,and remind the driver to avoid traffic accidents.This paper designs a set of automobile lateral blind area detection system based on STC12C5A60S2and ultrasonic sensor.This system USES multiple ultrasonic sensors combined to conduct real-time monitoring of external obstacles,timely upload the relative position between obstacles and vehicles,and the detection distance can be up to 5m,and the detection accuracy of the system can be less than 5%.The system can find and remind the driver of the relative position of side obstacle and car body,which is of great significance to avoid traffic accidents.
