A Systematical Approach for "System Item Integration and Testing" in Context of ISO 26262

The development of automotive systems and components are often in context of a development of a safety critical system with respect to electric/electronic faults. To ensure that these systems are developed adequately safe, standards like the ISO 26262:2018 have evolved which should guide the engineers through the whole development. In this paper a possible testing approach for automotive safety critical systems on system level and on vehicle level is shown. Based on real-world examples, the approach for functional testing, fault-injection testing and robustness testing is investigated in detail. Several important steps which are needed to end up with a fully tested and calibrated safety critical product in context of ISO 26262:2018 are explored. Potential challenges that need to be solved during the testing/calibration activities are highlighted and discussed in detail.
