某商用车仪表“死机”故障分析及优化设计

Failure Analysis and Optimization Design of a Commercial Vehicle Instrument Issue

随着科学技术的发展,越来越多的先进技术应用到汽车仪表中,嵌入式软件中断系统在汽车仪表软件系统中得到广泛的应用,由中断引发的故障往往具有隐蔽性和随机性[1]。本文结合某商用车仪表出现的“死机”问题,经过故障排查、分析,最后提出优化设计方案。

With the development of science and technology,more and more advanced technologies have been applied in automobile instrumentation,and embedded software interrupt system has been widely applied in automobile instrumentation software system.The faults caused by interrupt are often hidden and random.In this paper,combined with a commercial vehicle instrument“crash”problem,after troubleshooting,analysis,finally put forward the optimization design.
