The CoRE – Communication over Real-time Ethernet – research group works on communication solutions for time-critical applications using the Ethernet technology.
Real-time extensions for standard switched Ethernet have widen the realm of computer networks to safety-critical applications. This technology has been approved in the process automation, but its utilisation as an intelligent in-car backbone is novel.
The RECBAR project analyses the potential of the technology Ethernet as the central automotive communication infrastructure. RECBAR is an acronym for “Realtime Ethernet Backbone for Cars”. The project is an association between the Hamburg University of Applied Sciences (HAW), IAV automotive engineering, the research and development institute for computer science tools and systems (OFFIS) Oldenburg and the cooperative computing and communication labratory (C-LAB) in Paderborn. It was started in the third quarter 2012 and is scheduled for the period of 3 years.
The research and development of the working group is driven by involved and active students. We offer interesting topics for bachelor and master theses and a network of fellow students in the working group that support each other with their knowledge and experience. You have the opportunity to write your thesis in german or english.
To prove new communication concepts from experience is one goal of CoRE. Our prototype shows ambitious automotive applications, such as X-by-wire and broadband multimedia, over a flat homogenous in-car backbone network. By using small micro controller based embedded devices also in terms of computational power a realistic scenario is shown.
The performance analysis and validation of distributed real-time systems poses signiﬁcant challenges due to high accuracy requirements at the measurement tools. We introduce two low cost approaches to measure end-to-end latency and jitter of time-triggered Ethernet trafﬁc, synchronization and hardware precision.
Simulation tools are of vital importance to explore the technical feasibility and facilitate the distributed process of vehicle infrastructure design. CoRE is working on simulation models for the event-based simulation of real-time Ethernet protocols and state-of the art field busses. Our Real-time Ethernet simulation model is published as open-source module.
