- KonferenzbeitragSafety issues of integrating IVI and ADAS functionality via running Linux and AUTOSAR in parallel on a dual-core-system(Automotive - Safety & Security 2014, 2015) Schneider, Jörn; Nett, TillmannThe 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.

- KonferenzbeitragA Translation Semantics for Driving Simulation Languages(Software Engineering 2022 Workshops, 2022) Schneider, Jörn; Schneider, MarvinThe development of advanced driver assistance systems and automated driving functions requires the usage of driving simulation as integral part of the software engineering process. Moreover, safety standards such as SOTIF (ISO 21448) and legal regulations give driving simulation a key role for the safety validation of automated driving functions by OEMs and Tier-1s as well as independent or governmental institutions. Even as new standards for driving simulation languages come into use, this gives rise to the need for translation tools between different driving simulator languages. Two major challenges in this context for translation tools are hitherto not well addressed: 1. Adaptability to new languages or versions thereof. 2. Correctness of translation. We elaborate on some of the central challenges in this regard, present a prototype of a retargetable translator for driving simulation languages, and a suiting translation semantics, as first cornerstones of a future approach to validate or verify translations.
- KonferenzbeitragWhy current memory management units are not suited for automotive ECUs(Automotive - Safety & Security 2012, 2012) Schneider, JörnA major trend in automotive industry is to enrich driver and passenger experience with an increasing amount of consumer electronics and car-2-x functionality. A close interaction between this added functionality and the classical automotive domains allows for innovations that are valuable to the end customer and cannot be outplayed easily by devices with a pure consumer electronic origin. Innovations of this class require a tight coupling, for instance by executing programs from both worlds on the same microprocessor. The latter introduces many challenges, especially regarding reliability, security and safety of such systems. A unified memory management fulfilling the requirements of the consumer electronics and automotive application could help to address these issues and is a challenge by itself. This paper shows that the prevailing implementation scheme for memory management units (MMUs) is not suited for the needs of such systems and points out a solution direction.
