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. Since summer 2008 the CoRE group has been working on Ethernet-based network technologies for applications in harsh real-time environments, such as vehicles and planes.

To enable autonomous driving, driver assistance systems need a lot of information from different sources. Data from the immediate vicinity of the vehicle together with information provided via the Internet is processed in the operational control of the car. For example, route planning of e-vehicles must be adapted according to information about charging infrastructure. Currently, a subset of this information is already available offline in the vehicle. Another example of the necessary integration of a vehicle into the Internet are over the air software updates. In order to close vulnerabilities in the control software, these must be regularly supplied with updates. Time-accurate updates must be recorded online and linked to the appropriate hardware components. The integration of vehicles into the Internet requires its own security concepts.

RECBAR Prototype Car

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.

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 networks. Our simulation models are published as open-source module.

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 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.
