某车型仪表Dflash数据篡改故障分析

Fault Analysis of Dflash Data Tampering in a Vehicle Instrument

针对一种汽车仪表功能失效的问题,用诊断工具读取到内部数据被篡改,模拟故障发生的工况,设计实验,并通过对软件逻辑分析找到软件设计缺陷。通过优化设计,解决原设计缺陷,最后成功实施有效的解决方案。

Aiming at the problem of function failure of an automotive instrument, the internal data is tampered by diagnostic tools, the working condition of the fault is simulated, the experiment is designed, and the software design defects are found through logical analysis of the software. By changing the design, we can solve the original design defects, and finally successfully implement effective solutions.
