Safety issues of integrating IVI and ADAS functionality via running Linux and AUTOSAR in parallel on a dual-core-system

Abstract

The tight integration of In-Vehicle-Infotainment (IVI) applications and Advanced Driver Assistance Systems (ADAS) or even semi-automated driving functionality on the same hardware offers new chances for innovations in the automotive domain. One of the major challenges in this respect is to achieve a solution that satisfies the heterogeneous requirements from the involved application and operating system worlds and guarantees the necessary freedom from interference to attain the required safety according to ISO 26262 [ISO11]. This paper presents a prototypical solution and discusses the remaining challenges for the chosen virtualization-less approach. The prototype was developed for the practical use in the research project econnect Germany and successfully used in electric vehicles of a field study in Trier. An open source variant of AUTOSAR OS and Linux run together on the same processor of the system. Each operating system uses it own processor core. The chosen solution allows for the interaction between the different applications of the two operating systems and requires no virtualization layers thus avoiding additional resource demand and communication latencies.
