Next-generation cars will provide a multitude of advanced driver assistance systems (ADAS) functionality up to full autonomous driving support. These functions require high computational power and continuous software-maintenance (e.g. over-the-air update). Hence powerful general-purpose multi-core hardware and dynamic software-platforms/OS are being introduced to automotive systems. Furthermore these systems need to be certified according to safety standards. In this paper we highlight several challenges associated with the certification process. We thereby mainly focus on multi-core hardware architecture and RTOS aspects. One main question is whether Linux (with the PREEMPT RT patch) can be utilized and certified accordingly.
