E/E Architectures
 Cars provide more functionality and get smarter every day. Today’s vehicles have smart motor management in order to be fuel efficient, environment friendly and deliver comfortable driving characteristics. Driver and passengers are protected by intelligent systems, entertained by and able to access to different kind of information sources in and outside of the vehicle.
Customers like to customize their vehicles by adding specific options. In order to save costs vehicle manufactures need to reuse systems in different types of cars and suppliers use standard platforms to serve different vehicle manufactures.
Designing the Electrical and Electronic Architecture (E/E Architecture) of the modern vehicles is an important up-front work. The E/E architecture defines the breakdown of the system into subsystems, the interfaces between these subsystems, the functional partitioning and the physical layout within the vehicle. It also incorporates the overall design of the energy management, fault tolerance, interface specifications, communication standards, diagnostics and rules and guidelines for designing the subsystems.
Designing E/E architectures is a challenging job. In most cases the E/E architecture involves several or maybe the full range of vehicle types of the vehicle manufacturer. The design is supported with many advanced tools in order to reduce the complexity. Standardization is another solution to reduce the complexity. Standardization can be found in the areas of communication (Flexray, MOST, CAN, etc), architecture (Autsar, Jaspar, etc.) and diagnostics (e.g. ODX).
Dutch Highlights
NXP Flexray driver
FlexRay is the automotive standard for deterministic, fault-tolerant, high-speed data communication and it clearly delivers the networking performance demanded by new enhanced automotive applications such as brake-by-wire and steer-by-wire.
NXP has taken the lead in providing the best-in-class FlexRay solutions and driving standardization across the industry through its work with the FlexRay Consortium and a number of partners, who have driven innovation in the industry. Complementing the TJA1080A product, NXP recently released the TJA1081 and TJA1082 FlexRay node transceivers addressing car manufacturers’ need for high-speed, fault-tolerant communication systems and flexible and scalable electronic networks.

International activities
The FlexRay Consortium is an organization formed to drive the adoption of an open standard for high-speed bus systems for distributed control applications in automobiles. Since forming in September 2000, the Consortium has grown to include the automotive industry’s largest and most influential players. FlexRay development is being driven by the Core Partner companies, BMW, Daimler, Freescale Semiconductor, General Motors, NXP Semiconductors, Robert Bosch and Volkswagen. Various membership levels provide the ability to interact with the FlexRay Consortium working groups, propose ideas, participate in review meetings, and have early access to the specifications, as well as the opportunity to actively participate in the adoption of this global standard.
A complete list of member companies, directions on how to apply for membership and other information is available at the Consortium website, http://www.flexray.com.
