基于Android手机蓝牙技术的汽车故障诊断系统

摘要

为了实现在线监测和诊断汽车故障，针对传统手持式汽车故障诊断设备的不足，将手机蓝牙（Blue tooth）、CAN （Controller Area Network）总线、Android智能手机三者结合在一起，实现了基于蓝牙技术的无线汽车故障诊断系统。基于蓝牙技术的无线汽车故障诊断系统不仅能使汽车检修时方便快捷，而且能使普通大众人群直观地查看爱车的性能。%Aiming at the shortcomings of traditional hand‐held automotive fault diagnosis equipment ,we effectively combine mobile bluetooth ,controller area network(CAN) bus and Android smart phone together ,and build a wireless automobile fault diagnosis system based on bluetooth technology ,which can detect and diagnose automotive faults .This new car fault diagnosis system has fault diagnosis and data flow function .This technology not only make maintenance ECU convenient ,but also let people know their automotive performance .
