A Fail-safe Architecture for Automated Driving

The development of autonomous vehicles has gained a rapid pace. Along with the promising possibilities of such automated systems, the question of how to ensure their safety arises. With increasing levels of automation the need for fail-operational systems, not relying on a back-up driver, poses new challenges in system design. In this paper we propose a lightweight architecture addressing the challenge of a verifiable, fail-safe safety implementation for trajectory planning. It offers a distributed design and the ability to comply with the requirements of ISO26262, while avoiding an overly redundant setup. Furthermore, we show an example with low-level prediction models applied to a real world situation.
