Past and present projects of the CoRE Group

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.

The main key driver for new innovations in the automotive industry is the use of software controlled applications. The utilization has increased in a few years from 20 percent to 80 percent and forecasts claim that 90 percent of the automotive functions will be software in this decade. To minimize these costs, the software has to be tested in an early phase.

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.

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.
