A Structured Validation and Verification Method for Automotive Systems Considering the OEM/Supplier Interface

The released ISO 26262 standard for automotive systems requires several validation and verification activities. These validation and verification activities have to be planned and performed jointly by the OEMs and the suppliers. In this paper, we present a systematic, structured and model-based method to plan the required validation and verification activities and collect the results. Planning and the documentation of performed activities are represented by a UML notation extended with stereotypes. The UML model supports the creation of the artifacts required by ISO 26262, enables document generation and a rigorous check of several constraints expressed in OCL. We illustrate our method using the example of an electronic steering column lock system.
