New Automotive Systems in E/E are highly connected and are built on the collaboration of distributed functions. In addition, the requirements for safety concepts are getting more and more demanding due to higher degrees of automated vehicle functions.
In order to fulfill the norms like ISO26262, new methods to verify functional safety have to be introduced. System architectures and requirements have to be developed in parallel.
We will share how BMW introduced -and the benefits of- step approach models for multi-level system architectures and the joint use and re-use of these models, all based on a common development methodology and a modeling tool chain, which integrates existing solutions and data.
