    1st Workshop on Software Engineering for Applied Embedded Real-Time Systems (SEERTS)
    (Software Engineering und Software Management 2018, 2018) Höttger, Robert; Teßmer, Jörg
    Software engineering for research-intensive domains such as driver-assisted systems or autonomous driving in the automotive industry increasingly require highly sophisticated architectures as well as an optimized, safe, and secure interaction of a large number of actuators, sensors, and networked software components. In addition, connectivity, electric mobility, and heterogeneous development processes introduce new challenges for developers. The corresponding requirements in terms of real-time, causality, security, modularity, scalability or the use of various standards require appropriate domain-specific tools. Model-driven software development often plays an essential role for such tools. The SEERTS Workshop presents adequate technologies for the consideration of diverse and specific requirements within the embedded real-time domain (e.g. for robotics, automotive systems, etc.) and gives insights into their utilization in industrial applications.

    APP4MC: Application platform project for multi- and many-core systems
    (it - Information Technology: Vol. 59, No. 5, 2017) Höttger, Robert; Mackamul, Harald; Sailer, Andreas; Steghöfer, Jan-Philipp; Tessmer, Jörg
    Since especially the automotive domain increasingly utilizes multi- and many-core systems, appropriate models, analyses, and tooling are required to address challenges that were nearly non existent so far. APP4MC is an open source Eclipse platform that provides AUTOSAR compliant common data models namely AMALTHEA, basic parallelization features, visualizations, and the great possibility to add any existing tooling. For example, Eclipse Capra can be added to provide comprehensive traceability throughout the development processes but any proprietary, commercial, open-source, or prototypical implementations can be integrated. The platform enables the creation and management of complex tool chains including performance simulation and validation. The entire community benefits from reduced hardware costs, faster time to market, higher quality systems, and rapid adoption. APP4MC is not retricted to the automotive domain and utilizable in robotics or generic real-time systems as well.

    Automated Continuous Evaluation of AUTOSAR Software Architecture for Complex Powertrain Systems
    (INFORMATIK 2017, 2017) Venkitachalam, Hariharan; Powale, Kalkin Anand; Granrath, Christian; Richenhagen, Johannes
    Connectivity of the vehicle to heterogeneous information sources is one of the key factors which lead to complexity of automotive software architecture. The information content from external communication sources modifies the structure, content and the synchronization of control algorithms. In addition to this, time and cost constraints for software development are challenging. With increasing complexity and reduction of development time, ensuring software quality is one of the foremost priorities of vehicle manufacturers. Software architecture plays an important role in ensuring quality by implementing design principles which enhance non-functional quality attributes of the automotive software. The extent to which a software architecture definition fulfills the quality requirements is not verified at early stages of development. As a consequence, design problems are transferred to later stages of development thereby causing rework of software artifacts. The paper focuses on a tool-based evaluation of non-functional quality characteristics using the concept of Continuous Integration for AUTOSAR-based transmission control software. The suggested approach enables early and continuous evaluation of software architecture thereby improving software quality

    Enhancing Automotive AUTOSAR Environments with Artificial DNA
    (INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft (Workshop-Beiträge), 2019) Hutter, Eric
    In order to cope with the ever-increasing complexity of automotive embededded systems, bio-inspired techniques can be employed. We propose an organic concept based on artificial DNA (ADNA) and an artificial hormone system (AHS) that can be used to realize highly reliable, robust and flexible automotive systems. However, computational resources and communication bandwidth are often limited in automotive environments. Additionally, the AUTOSAR Classic Platform as the de facto standard for automotive Electronic Control Units (ECUs) does not support dynamic system behavior. Nevertheless, in this paper we show that the dynamic concept of ADNA and AHS can be successfully applied to a statically configured Classic AUTOSAR environment with moderate computational resource usage. While the communication via CAN bus (Controller Area Network) imposes some limitations, we propose ways of resolving them.

    Entwicklungsunterstützende Analysen und Tests für AUTOSAR Systeme
    (INFORMATIK 2017, 2017) Englisch, Norbert; Hardt, Wolfram
    Durch die Einführung des AUTOSAR Standards in der Automobilindustrie ist es möglich funktionsorientiert und hardwareunabhängig Software zu entwickeln und wieder zu verwenden. Realisiert wird das in AUTOSAR durch ein horizontales Schichtenmodell, welches die Bereiche Basissoftware, Runtime Environment und Applikation definiert. Durch diese klare Trennung hat sich eine Vielzahl von heterogenen Werkzeugketten mit unterschiedlich spezialisierten Produkten etabliert. Das führt zu neuen Herausforderungen in der Automobilindustrie, da die Softwarequalität und die Suche nach einer optimalen Konfiguration für ein Steuergerät nun immer wichtiger werden. Unser Ansatz bietet während der Entwicklung eines AUTOSAR Steuergerätes Unterstützung zur Sicherung der Softwarequalität und der Konformität zum Standard durch statische Analysen. Des Weiteren können semi-automatisch dynamische Tests generiert und auf der Zielplattform ausgeführt werden, um die Basissoftware und die Runtime Environment auf ihre Funktionstüchtigkeit zu überprüfen. Unser Ansatz greift auf AUTOSAR konforme Mechanismen zurück und ist versions-und herstellerunabhängig.

    Quo vadis, AUTOSAR?
    (INFORMATIK 2017, 2017) Jakobs, Christine; Tröger, Peter
    AUTOSAR is the de-facto standard for developing automotive software. It is utilized by leading car manufacturers and suppliers as a common platform for software portability and interoperability. Future car applications such as autonomous driving and Internet service usage change the static deployment model on single ECUs towards the classic idea of a dynamic distributed system. This paper identifies properties of AUTOSAR which do not match to such upcoming scenarios. We discuss how established patterns from distributed software development may contribute to an improved version of AUTOSAR that is more suited for current and future applications.

    Rapid Prototyping in AUTOSAR Based Systems
    (INFORMATIK 2017, 2017) Khan, Owes; Englisch, Norbert; Hardt, Wolfram
    Application prototypes involving complex algorithms for purposes like ADAS are often developed on PC based systems. For validation, these prototypes must be executed on automotive embedded systems. Furthermore, with increasing industry demand of AUTOSAR based ECUs, integration with AUTOSAR environment also becomes a necessity. The process in itself is time consuming due to the fulfilment of various steps involved in the AUTOSAR methodology. On the contrary, for rapid prototyping, time and effort for non-functional requirements should be minimal. A concept for automated integration of non-AUTOSAR compliant prototype codes within an AUTOSAR system, along with application specific configuration and generation of the complete system is proposed by this paper. The main aim is focused on memory usage reduction of AUTOSAR BSW along with the integration of prototype codes to facilitate an AUTOSAR Processor-in-Loop test environment for the application.

    YellowCar
    (INFORMATIK 2017, 2017) Englisch, Norbert; Khan, Owes; Mittag, Roland; Hänchen, Felix; Heller, Ariane; Hardt, Wolfram
    Modern automotive industry develops software functionalities such as Advanced Driver Assistance Systems (ADAS) as software components, spread over several ECUs. Typical interconnection structure is a network, e.g. a CAN bus system. Up to date specifications and standards define operating system functions. During the development process, several questions such as functional test, performance evaluation, and optimization of software architecture for hardware independent implementation to enable reuse and standardization must be considered. For this reason, YellowCar has been developed as AUTSOAR based demonstration platform for evaluation of design methods and education of students in design methodology. Several applications demonstrate successfully YellowCar platform suitability.
