摘 要:为了提高驾驶安全性,在驾驶员超车或变更车道时需要提供盲区探测与警示,以dsPIC33CK32MP502单片机为核心,结合仪表盘以及FZ-SE01超声波测距模块,研制了一种车辆盲区探测报警装置。根据车辆不同的行驶状态选择探测不同的盲区,通过超声波传感器探测盲区是否有障碍物;当超声波传感器探测到盲区存在障碍物,并且障碍物与车辆的距离小于预设的安全距离时,通过报警装置及时向驾驶员提出警示。文章研制的装置具有功耗小、灵敏度高、成本低廉、布置方便的优点,有效的保障了驾驶安全。关键词:汽车;盲区探测;超声中图分类号:U463.99 文献标识码:A 文章編号:1671-7988(2019)01-104-03

Abstract: In order to improve driving safety, blind zones detection and warning are required when the driver overtakes or changes lanes. We developed a vehicle blind zones monitoring and alarming device that takes dsPIC33CK32MP502 MCU, instrument panel and FZ-SE01 ultrasonic ranging module. It can select and monitor the blind spots of the vehicle according to different driving states, and detect whether there is an obstacle in the blind zones through the ultrasonic detecting device. When itdetects that there is an obstacle in the blind zones, and the distance between the obstacle and the vehicle is less than the preset safety distance, the device warns the driverpromptly. The device has the advantages of low power consumption, high sensitiv...
