现代汽车中不同功能的微机控制系统不断增加,由于汽车通常工作在高温、振动、信号干扰甚至潮湿等极为不良的环境下,经过一定时期的使用,一些车辆的微机控制系统会出现不同特征的故障,这些故障通常可以归纳为两类:一类称为硬故障;另一类为软故障。目前诊断微机控制系统硬故障的仪器设备较多,而诊断软故障缺乏必要的仪器设备。为了提高排除软故障的准确性和工作效率,需要有更可靠的解决方法和仪器设备。为此,笔者开发了微机控制系统软故障分析
Different functions of microcomputer control system in modern automobiles are increasing. Since vehicles usually work in extremely bad environment such as high temperature, vibration, signal interference and even humidity, after some period of use, the microcomputer control system of some vehicles may have different characteristics of faults , These faults can usually be summarized into two categories: one is called hard fault; the other is soft fault. At present, there are many instruments and equipment for diagnosing computer control system hard faults, while the diagnosis of soft faults lacks the necessary equipment. In order to improve the accuracy and efficiency of troubleshooting soft faults, more reliable solutions and equipment are needed. To this end, I developed a computer control system soft fault analysis
