STM32的车载雷达预警抬头显示器设计

本文是基于STM32便携式车身全方位雷达抬头显示器的硬件和软件程序设计.与传统 OBD车载器相比,该车载抬头显示器既可以监测车身在泊车过程中的危险距离并可产生预警提示,又可以在车辆运行中精确定位安全距离的方位.该方案设计的全方位抬头显示器可以投影显示汽车运行参数和周围雷达测量距离,能够给驾驶人员提供一个驾驶安全预警提示值.结合STM32控制单元作为数据处理依据,使用超声波雷达传感器测量车辆周围距离信息,配合OBD II接口读取车辆信息,最终将提示信息显示在抬头显示器上.

Car Radar Warning Heads-up Display Based on STM32

In the paper,the portable omni-directional radar heads-up display hardware and software programming based on STM32 are designed.Compared with the traditional OBD vehicle-mounted device,the vehicle mounted heads-up display device not only can alert the dangerous distance during parking,but also can accurately locate the safe distance during the vehicle operation.The all-round heads-up display can display the vehicle operating parameters and the surrounding radar measurement distance,which provides a driving safety warning value for the drivers.Combining with the STM32 control unit as the data processing,the use of ultrasonic radar sensors can measure the distance information around the vehicle,then it can read the vehicle information using the OBD II interface,finally the mes-sage is displayed on the heads-up display.
