Dependable and Flexible Electrical Architectures. This is a newly started research project that will investigate and develop new techniques for implementing highly flexible, dependable and cost-efficient automotive electrical systems. Our work in this project starts in January 2010.
Project duration: 2010 – 2013
Cost Efficient Dependable Electronic Systems – aims at developing low cost electronic systems and software for active and passive safety systems for road vehicles. The project is a joint research effort involving Autoliv Electronics, Chalmers, SP- Technical Research Institute of Sweden, Volvo Car Corporation and Volvo Technology. The industrial part of CEDES ended in December 2008; the academic part continues until the end of 2010.
Our contributions to CEDES are in two areas. In one subproject we study techniques for making brake-by-wire systems immune to transient hardware faults, such as radiation induced single event upsets. We have designed and are currently evaluating several low-cost software implemented fault tolerance mechanisms. Extensive fault injection experiments have shown that these mechanisms can effectively reduce the risk of catastrophic failures in electronic brake controllers.
In the other subproject we are developing protocols for redundancy management and system reconfiguration in distributed active safety systems. The goal is to develop real-time consensus protocols which allow correctly working computers to quickly agree on the current status of the system in the presence of asymmetrical failures, i.e., failures that are perceived differently by different computers. Such failures are in general difficult to cope with and may lead to that otherwise correct computers disagree on the system state.
Project duration: 2005 – 2010
Assessment, Measurement and Benchmarking of Resilience – is a research coordination action funded by the European Commission under FP7, in which we together with six European partners are developing a research roadmap for resilience assessment, measurement and benchmarking technologies. One important goal for AMBER is to develop an open, web-based data repository for field failure data and raw data collected in empirical studies of resilience.

The ITEA-2-supported research project TIMMO (TIMing MOdel) is after a breakthrough in the area of automotive system timing management using a common, standardised approach for handling all timing-related information during the development process. The complexity — and the cost — of the development cycle is reduced significantly, while reliability is improved. TIMMO is about developing a Timing Augmented Description Language (TADL) and an accompanying methodology that provide
These are fundamental prerequisites to avoid costly delays in vehicle start-of-production dates and, in turn, to assure confidence in the dependability and quality of a given solution.
TIMMO will have three major results: A formal language for modelling timing aspects, an accompanying methodology that describes how to apply the language in the development process, and a set of case studies serving as example applications and as validators for the language and methodology.
The goal of TIMMO is to establish a standardised infrastructure for the handling of timing for the European automotive market, complementing the automotive standards AUTOSAR and EAST-ADL. This requires major industrial players in the field as well as leading European research institutes to participate. Therefore, the TIMMO consortium consists of four groups:
