Cooperation between Vector Informatik and AbsInt
paves the way for autonomous driving

Stuttgart and Saarbrücken, April 9, 2024 — A key requirement for autonomous driving and x-by-wire systems is the correct timing of fail-operational systems. Coordinated software tools and a close cooperation between Vector Informatik and AbsInt make it easier for ECU developers to analyze the worst-case execution time (WCET) of projects based on MICROSAR from Vector, and to prove that the timing behavior of autonomous driving systems meets the strict safety standards and requirements.

The collaboration between Vector and AbsInt brings together the expertise of two industry leaders in the field of safety-related embedded systems. The partners attune Vector’s safety-certified MICROSAR platforms with AbsInt’s rock-solid timing analysis tools. This enables predictable systems that are able to fulfill significant fail-operational requirements.

With the advent of “hands-off” autonomous driving, vehicle control is shifted to autonomous systems within specified scenarios. During active driving, these systems need to adhere to very strict functional-safety and timing requirements. It is essential to have precise knowledge of the upper bound on a function’s runtime, also referred to as its worst-case execution time (WCET). Determining the WCET is a challenge and typically requires significant effort. By joining forces, Vector and AbsInt enable easier analysis of systems where timing is absolutely crucial to functional safety.

Fail-operational systems are systems that must continue to operate even in the presence of single faults or failures, such as autonomous driving or x-by-wire systems. These use cases require a high degree of safety, reliability, and availability, as well as predictable and deterministic behavior. Vector’s MICROSAR platforms offer a state-of-the-art solution for developing fail-operational systems. Based on the AUTOSAR standard and additional extensions, they support in the realization of adaptive and scalable software architectures. AbsInt’s timing analysis tools enhance Vector’s solution by providing rigorous and certified methods for determining the worst-case execution time of the software functions, which is a crucial factor for ensuring the proper timing behavior of the system and avoiding timing faults.

Our collaboration with AbsInt is essential to enable WCET analysis of complex automotive software. Together, we are shaping the future of fail-operational systems, ensuring safety in autonomous driving”, says Dr. Falco Bapp, Manager Solution Management at Vector.

Good analysis precision requires a precise understanding of the underlying Vector software. Our joint customers benefit from many years of close cooperation”, adds Dr. Christian Ferdinand, CEO of AbsInt.

Furthermore, Vector’s TA Tool Suite and AbsInt’s timing analysis tools complement each other to provide a full timing tool chain for all phases of the project lifecycle. The tools assist developers in improving the timing behavior of their fail-operational systems, and in demonstrating compliance with safety standards and requirements.

AbsInt will be presenting its timing analysis tools at the Embedded World 2024 in Nuremberg (hall 4, booth 138).
