基于单片机的汽车油门防误踩系统研究报告样本

基于单片机的汽车油门防误踩系统讨论报告设计者: 唐洋、 田恬、 陈鹏、 潘迪指导老师: 王起明学院: 机电工程学院摘 要本文介绍了基于 AT89S52 单片机控制防止误踩汽车油门的系统的设计。利用角速度传感器、 超声波距离传感器、 LCD1602 液晶显示屏、 继电器控制电路、 AT89S52 单片机等组成此设计的硬件部分。角速度传感器和超声波距离传感器将采集到的角速度数据和距离数据传送给 AT89S52 单片机, 单片机再对接收到的数据进行处理和推断, 将处理的结果传送 LCD1602 液晶显示屏上显示, 而且控制外围器件, 电子油门开关和汽车刹车部分, 同时经过声光报警进行警示, 实现此设计的完全功能。关键词: 数据采集系统; 角速度; 距离; AT89S2; 汽车目 录摘要 ·······························································2第一章 绪论 ·······················································41.1 课题的背景·················································41.2 讨论意义···················································41.3 国内外讨论现状·············································4第二章 关键技术···················································62.1 汽车安全状态的确定·········································62.2 车前障碍物信息的猎取·······································62.3 误踩油门判定方法···········································6 2.3.1 误踩油门踏板角速度信息的检测和推断···················7 2.3.2 前方障碍物距离的检测和推断··························7第三章 系统总体方案设计··········································93.1 系统总体方案··················...
