We consider in this paper switched systems, a class of hybrid systems recently used with success in various domains such as automotive industry and power electronics. We propose a state-dependent control strategy which makes the trajectories of the analyzed system converge to finite cyclic sequences of points. Our method relies on a technique of decomposition of the state space into local regio...

Working Paper Series Abstract Hierarchy is a generic structure in which levels are asymmetrically ordered. In an industry setting, classic supply chains display strict hierarchy, whereas clusters of firms have linkages going in many different directions. Previous theory has often assumed the existence of the hierarchical relationships among firms and empirical work has focused on a single level...

Microelectromechanical ~MEMS! gyroscopes have wide-ranging applications including automotive and consumer electronics markets. Among them, complementary metal-oxide semiconductor-compatible MEMS gyroscopes enable integration of signal conditioning circuitry, multiaxis integration, small size, and low cost. This paper reviews various designs and fabrication processes for integrated MEMS gyroscop...

Semiconductor products are used today in major applications such as automotive electronics, consumer data processing, industrial wired and wireless communications. Without...

Over the past years, developing automotive software has been of an Electronic Control Unit (ECU)-specific nature despite the wide range of invehicle electronics. With the increasing maintainability cost of such an approach, the AUTomotive Open System Architecture (AUTOSAR) has emerged as a collective effort among different elements in the automotive industry in order to provide standardized and...

Leading OEMs have made it very clear that Ethernet is on its way into automotive electronics. At the same time, the design space is still very huge. What is the “best” topology, switch architecture, and higher level protocol? For this, the automotive OEMs need a clear strategy and tools. TU Braunschweig via its innovation center, iTUBS, is developing the foundations; Symtavision is working towa...

Standardization is very much the trend in the development of automotive electronics. The use of open architectures and configurable components are intended to let developers focus more on the innovative and differentiating aspects of the development process. AUTOSAR (AUTomotive Open System ARchitecture) has the stated goal of standardizing a common open automotive software architecture. It is a...

This paper describes an approach for risk-based testing of Bluetooth functionality in an automotive environment, recently studied as part of the ITEA-2 research project DIAMONDS. In the past two decades the functionality of infotainment systems of a modern car increased in complexity. Based on the worldwide evolution towards an information age the driver requests permanently increasing number o...

Many innovations in the automotive industry are based on electronics and software, which has led to a steady increase of electronic control units (ECU) in cars. This brought up serious scalability and complexity issues in terms of cost, installation space, and energy consumption. In order to tackle these problems, there is a strong interest to consolidate ECUs using virtualization technologies....

Current automotive electrics and electronics (E/E) architectures are very complex and face the challenge to provide easy integration of additional and even more complex functionality such as automated driving. Furthermore, the end-customer is used to the possibility of easy personalization, adaptivity or extensibility of the electronic systems with new hardware or software. Since this possibili...
