Motor control in air conditioners with dual sensor less FOC and active PFC
Improved energy efficiency and reduced system costs are the driving factors in modern motor control designs. Sophisticated motor control concepts with sensor less Field Oriented Control (FOC) and Power Factor Correction (PFC) help to fulfill these demands. The article shows how these concepts can be used in an air conditioner design for vehicles.

Knock detection using wavelets
The authors describe a new engine knock detection approach based on a wavelet transform techniques. They conclude that a new adaptive knock detection approach is feasible using wavelet transform and that future work should focus on efficient hardware implementation.
Copper-based piezo actuators offer improved durability
Piezo fuel injection systems have become established as the state of the art in passenger vehicles. A new generation of actuators based on an innovative ceramic technology with copper inner electrodes now offer much better performance and durability.<
CST EM Studio and Simulink for the dynamic simulation of a two-state linear actuator
This article shows a common approach to the simulation of electromechanical problems. A parametric set of 3D magnetostatic simulations are carried out using CST EM Studio (CST EMS) on a linear actuator in order to obtain its electromagnetic characteristics for use in Simulink where both the electrical and dynamic performance can be obtained i.e. coupling with mechanical system: spring, damping, etc. and coupling with external circuit with a rectangular voltage waveform.

FIBEX XML format and AUTOSAR development
Engineers planning to start Autosar projects for the first time can revert on existing tool chains, at least in part: The Fibex protocol is very similarly structured, and in many cases existing Fibex tools can be adapted to Autosar.
Simtest Simulation: A Powerful Tool for Embedded Software Development
Embedded software is no longer written in assembly language macros. In fact, the same high-level languages and tools used for writing embedded software are the same tools used for designing application software of non-embedded computers. However, embedded software is still decidedly different from non-embedded application software.
SoC integrated power supply aims to reduce ECU system cost
New SoC designs are needed to integrate more logic and analog features in order to lower system cost. Freescale's approach for the auto market is to integrate multicore, SRAM, flash and analog IP on a single chip.

New transmission mechanisms for MOST enable powerful video applications
The MOST infotainment network was originally launched with a bandwidth of 25 Mbps, a bandwidth that was more than adequate for audio applications. The latest generation, MOST150, has a capacity of 150 Mbps, and is designed to serve powerful video and packet data applications in your car, as well as classic audio applications. Besides the higher bandwidth, MOST150 introduces additional transmission mechanisms such as isochronous data transfer over the synchronous network.
Untangling the Challenges of the Connected Car
Increasingly, car owners want to integrate their loved living room consumer electronics environment into their set of wheels. Plus they don't want to forego connectivity. This creates headaches for automotive electronics experts: Too different are technical requirements and product life cycles. An approach to solve the problem could be a flexible, upgradeable software environment.
Low-power Intel Architecture Platform for In-vehicle Infotainment
Fast-changing connectivity and multimedia demands for in-car infotainment increasingly collide with the long development cycle in this industry. An in-vehicle infotainment platform optimized for automotive environments could gap the bridge between the divergent requirements.

Moving model-based development into safety-critical embedded applications
How to use the SCADE (Safety Critical Application Development Environment) to help model problems of determinism and ambiguity in many safety-critical control system applications.
CCD / CMOS Cameras: Eyes for Cars
Cameras increasingly are equipped with cameras — for purposes ranging from rear view back-up cameras to devices generating the input for smart driver assistant systems. The requirements vary as much as their applications, and designers should know which sensor type fits for which kind of application.
Powering Reliability - Ensuring Automotive Quality beyond AEC Q100/101
The increasing complexity of electronic systems in modern automobiles reached a level where a paradigm shift both in design and the qualification process becomes mandatory. Releasing products according AEC-Q101, a sampling based method derived from ammunition testing in the 1940s and implemented in the 1960s for automotive, is absolutely insufficient to support a zero defect strategy. The combined use of state-of-the-art design tools and methods for robustness validation allows designers to cope with these challenges
