FlexRay demonstrator for certification

An always increasing number of electronic control units monitor and operate drive-train and other safety related functions in automotive applications. Transferring this kind of functionalities like steering or breaking to these devices requires high dependability and reliability during every possible operation scenario. Therefore developing and certifying safety related electronic components to...

Simulation-Based FlexRay

This article presents a case study on how the Open Verification Methodology (OVM) was successfully applied to implement a SystemVerilog simulation-based conformance test environment for next generation FlexRay TM 3.0 Communications System controllers. Complex application requirements and a need to run conformance tests on multiple vendor simulators, including Mentor’s Questa, with reliable, rep...

طراحی و پیادهسازی سیستم یادآور واکسیناسیون کودکان مبتنی بر سرویس پیام کوتاه

Background: Most problems related to quality of care and patient safety are related to human negligence. One of the causes of these problems is forgetting to do something. This problem can be avoided with information technology in many cases. Some forgotten are very important. Among these is failure to comply with vaccination schedule by parents that can result in inappropriate outcomes. In thi...

Embedded Software for FlexRay Systems

Fehlertoleranzanalyse des FlexRay Startup-Prozesses

Zusammenfassung. Die FlexRay-ProzedurenWakeup und Startup sollen eine konsistent-synchrone Kommunikation bezüglich eines TDMA verwandten Verfahrens herstellen. Beide Algorithmen werden in dieser Arbeit abstrakt modelliert und mit Hilfe des Model Checkes SPIN bezüglich Terminierung analysiert. Die Ergebnisse zeigen, dass in bestimmten Fehlerszenarios die Verwendung von Central Bus Guardians, die...

Scheduling of the FlexRAY communication protocol respecting AUTOSAR FlexRay COM stack

The objective of the paper is the formulation and solution of the frame packing and scheduling problem for the static segment with respect to AUTOSAR FlexRay COM stack. There are several other works on the static segment scheduling. The problem becomes more constrained since the release dates and deadlines of the signals are taken into account. While assuming release dates and deadlines to be m...
