BMW, DaimlerChrysler, Motorola and Philips present their joint development activity related to the FlexRay communication system that is intended for distributed applications in vehicles. The designated applications for powertrain and chassis control place requirements in terms of availability, reliability and data bandwidth that cannot be met by any product currently available on the market under the testing conditions encountered in an automobile. A short look back on events so far is followed by a description of the protocol and its first implementation as an integrated circuit, as well as its incorporation into a complete tool environment.

The BMW Group is the first car manufacturer introducing FlexRay in series projects. Start of production is September 2006, where a pilot application is implemented in the chassis domain of the new BMW X5. In 2008 FlexRay will form a substantial part of the overall electronics architecture in form of a FlexRay network connecting multiple ECUs implementing chassis, powertrain, and driver assistance applications.
