摘　　要：CAN总线被广泛应用于汽车通信。随着汽车电控系统结构的日益复杂,电子系统出现故障的可能性也相对增加,同时对故障发生原因也变得越来越困难,从而极大影响了客户的用车体验。本文以汽车诊断仪为研究对象,分别介绍有线式诊断仪、无线式近距离诊断仪和无线远程式诊断仪技术路线所需要的硬件设备和优缺点,并进一步分析汽车诊断技术未来发展趋势。CAN bus is widely used in automobile communication.With the increasingly complex structure of the automobile electronic control system,the possibility of failure of the electronic system is also relatively increased.At the same time,it is becoming more and more difficult to find the cause of failure,which greatly affects the customer's experience during the use of the automobile.This paper takes the automobile diagnosis instrument as the research object,introduces the technical route and the required hardware equipment of the wired diagnosis instrument,the wireless short-range diagnosis instrument and the wireless remote diagnosis instrument;The advantages and disadvantages of the three diagnostic techniques are analyzed.The future development trend of automobile diagnosis technology is further analyzed.
