Wie kann die funktionale Sicherheit in Fahrzeugen zukunftssicher und effektiv gewährleistet werden? Und wie kann dies speziell in elektrifizierten Antrieben gelingen? Mit dieser Aufgabenstellung haben sich AVL in Kooperation mit dem LaS³ und der Universität der Bundeswehr München in einem Forschungsprojekt beschäftigt. Die Antwort lautet: Die automatischen Speichertests in Zusammenspiel mit der Programmfluss-Überwachung und redundanter Hardware können besonders effektiv durch die „Codierte Verarbeitung“ ersetzt werden. Denn hier wird die Diversität in Software erhöht, um die aufwendigere und kostspielige Redundanz von Hardware zu reduzieren.
Genetic optimization of real-time multicore systems with respect to communication-based metrics

Reasonable integration of gesture-based automotive HMI-functionality offers potential safety benefits by reducing driver distractions and glance times to operate tertiary in-car devices. Stereo camera systems are a well investigated choice to perform the task of generating depth data for spatial gesture recognition. This paper describes the functionality of our stereo vision software, which is intended for application in a target system based on CMOS wafer-level cameras. The retrieved point cloud data was passed to a gesture-based sample application.
Software process models are fairly abstract tools for organizing large, complex software development projects. Since particularly undergraduate students commonly do not have any experience in being part of such a project, their understanding of the benefits and shortcomings of particular process models is very limited. Even more, frequently they are not aware of the need to follow a particular process model since their previous one-person software assignments were too small for requiring any such model at all.

Optimizing Software Integration Testing by Considering Integration Testability and Test Complexity

The requirements for safety-related software systems increases rapidly. To detect arbitrary hardware faults, there are applicable coding mechanism, that add redundancy to the software. In this way it is possible to replace conventional multi-channel hardware and so reduce costs. Arithmetic codes are one possibility of coded processing and are used in this approach. A further approach to increase fault tolerance is the multiple execution of certain critical parts of software. This kind of time redundancy is easily realized by the parallel processing in an operating system. Faults in the program flow can be monitored. No special compilers, that insert additional generated code into the existing program, are required. The usage of multi-core processors would further increase the performance of such multi-channel software systems. In this paper we present the approach of program flow monitoring combined with coded processing, which is encapsulated in a library of coded data types. The program flow monitoring is indirectly realized by means of an operating system.
