![]() This development of project and safety requirements drives the DV Plan Analysis ISO 26262 tables 10-12 below show how these requirements are determined for safety related projects. Once the customer requirements and safety requirements driven from ISO 26262 Tables 1-3 in the figure above, are determine the requirements for testing and analysis are developed. The DFMEA process is used in most Dana projects.įor higher safety designs (ASIL-C and above) Dana also uses deductive analysis such as fault tree analysis (FTA) and quantitative failure modes, effects and diagnostic analysis (FMEDA). DFMEA drives how to determine what components and subsystems require special attention in testing to determine the system will be robust enough to meet the requirements. For non-safety related designs Dana uses a less rigorous process with many steps shared with the ISO-26262 process.Īs the Table 1 above shows, design failure mode effects analysis (DFMEA) is an inductive method used to analyze what the effects of a failure would be and what could cause those failures. The ISO 26262 tables determine the safety related analysis and requirements for the design verification. The report documenting the design verification testingįor safety related designs Dana follows ISO-26262 processes which drive the analysis and testing from tables that define the level of rigor for the different automotive safety integrity levels (ASIL).The plan for the design verification testing.The process for doing this verification is called Design Verification (DV).ĭV has multiple steps which are documented in a Design Verification Plan and Report (DVP&R) for testing of the design, and in analysis reports. ![]()
