Due to the hybridization and change of hydraulic systems into electrical systems, the number of electric commutated motors in vehicles is increasing dramatically. There is a trend towards brushless motors, as they have no wearing parts (brushes), low acoustic buzz and very low torque rippling. In order to ensure exact commutation of electric motors the position of the rotor has to be measured very...
This article describes a new anisotropic-magneto-resistive-effect (AMR) based current sensor system, based on a ‘system-in-a-package’ approach. It is designed for high resolution and fast electronic measurement of DC, AC up to 500 kHz, or pulsed currents [1]. As the concept is based on an external primary current bar, it can easily be adapted to a wide range of applications for different nominal primary...
The development of smart systems for mobility, especially the development of electronic systems for hybrid and electric cars, introduces a new dimension of complexity – the traditional separation of different physical domains and their corresponding engineering disciplines will be repealed. To address this new complexity new design methodologies are required. Due to several advantages virtual prototyping...
Besides the use of sensors for applications in the automobile, there is an increasing demand for smart sensors that can be applied in the phase of research and development of electronic components for automobiles. For these requirements impedance-based micro-sensors were developed based on a technological platform. One example, the micro condensation sensor, is presented here. Thermally connected...
Warm bodies like humans or animals emit radiation in the long-wave infrared band (8 to 14 μm) which can be used for pedestrian detection in an automotive application. Fraunhofer-IMS has developed an advanced 640 x 480 (VGA) IR detector (IRFPA=infrared focal plane array) based on uncooled micro bolometers with a pixel-pitch of 25μm. The IRFPA is designed for thermal imaging applications with a full-frame...
Traffic volume is steadily increasing whilst infrastructure capacities stay the same – based on this prediction efficient processing of floating car data (FCD) and extended floating car data (xFCD) is of great significance to ensure future individual mobility. By taking into consideration results of existing FCD/xFCD studies the major subject of this paper is to define base requirements for collecting...
When talking about electrical mobility, we mainly think of extending the cruising range of vehicles. Energy management works while driving, charging, or parking. System requirements for e.g. energy saving brings management of control networks to a higher complexity level and results in new and extended requirements for semiconductor devices. These are mainly “selective wake-up capability” to realize...

The forthcoming Smart Grid is expected to implement a new concept of transmission network which is able to efficiently route the energy produced from both concentrated and distributed plants up to the final user with high security and quality of supply standards. Therefore the Smart Grid is expected to be the implementation of a kind of “internet” in which the energy packets are managed similarly...
With the aim of decreasing today‘s dependency on oil, a growing interest in vehicles powered by alternative fuels, such as electric vehicles, has been generated. However, the successful incorporation of electric vehicles in the actual transportation system depends on overcoming of two main barriers: the low range of the electric vehicles in comparison with traditional internal combustion vehicles,...
This paper presents the advances of the EPV (Electrically Powered Vehicle) Project, which searches the analysis and design of specifications of a new energy efficient urban transport system. In these days where Information and Communication Technologies (ICT) play a key role in our society and the environmental concern is increasing, opportunities of linking both issues are arising, which will help...
The presented work focuses on a generic software architecture as a basis for complex hybrid control and energy management strategies for a very wide range of applications. A clear and transparent mode prioritization together with the requests generation form the fundamental structure within the proposed architecture which always ensures the secure handling of the complex system. Different application...
HEV-EV batteries are characterized by high specific power, energy, efficiency and long life. These batteries will soon play a prominent role as innovative electrochemical storage systems in renewable energy plants and distributed power stations as well as in smart power systems for sustainable vehicles such as hybrid and electric vehicles. There is now a new dimension of improved safety, reduced costs,...
