基于STM32单片机的教练车转向轮转角显示仪设计与实现

Design and Implementation of Steering Wheel Angle Display Instrument of Training Vehicle Based on STM32 Single Chip Microcomputer

针对汽车转向轮转向角度把握不好,易造成的车库移位、刮擦、追尾等事故,为帮助驾驶初学者,实时监控汽车转向轮的方向,降低交通事故发生率,开发了基于STM32单片机的汽车转向轮转角显示的系统设计,实现了汽车转向轮转角检测、按键控制、数据显示、WiFi通信、报警提示等功能;实现了汽车转向轮检测角度范围为30~40°,测量精度为1°的指标;如果汽车转向轮转角不在设置阈值范围内,则通过声音报警提示,通过按键调整汽车转向轮转角阈值,通过对系统的测试,测试结果达到最初设计的要求.该套设备可为初学者和教练员教学带来便利,也为驾驶学校教练车装备智能化提供借鉴。

Aiming at the Accidents of easy garage displacement,scraping and rear end collision caused by poor grasp of the steering angle of automobile steering wheel,in order to help drivers and beginners to monitor the direction of steering wheel in real time,and reduce the incidence of traffic accidents,the system of automobile steering wheel angle display based on STM32 single chip microcomputer is implemented,the system functions of automobile steering wheel angle detection,key control,data display,WiFi communication and alarm prompt are realized.The system realizes the indexes with 30°to 40°of steering wheel range and 1°of measurement accuracy.If the steering wheel angle data exceeds the set threshold,it will be prompted by the audible alarm,the key is used to adjust the threshold of steering wheel angle.By the system test,the experimental results fully meet the requirements of the original design.This set of equipment can not only bring convenience to the teaching of beginners and coaches,but also provide reference for the intellectualization of coach equipment in driving school.
