New vehicle functions are often using information from several vehicle systems to increase performance or to save cost. To reduce the more and more increasing number of functional interconnections the data flow in the entire vehicle has to be restructured. We show an approach clustering functions into 5 major modules but not according to their physical or organizational dependability but for optimizing the entire data flow. The function interfaces are compliant to AUTOSAR definitions. The migration path from today to this new functional architecture is shown for the electrical wedge brake and the integrated vehicle control platform.

The eBrake is a novel self-reinforcing electromechanical wedge brake, which operates around the point of maximum self-reinforcement in order to minimise actuation forces. Beyond this point, the system would be unstable without an electronic controller. It is therefore important to demonstrate that this controller is robust to the range of parameter variations likely to be encountered in practice. The first stage of this process can be conducted on a dynamometer under laboratory conditions, to ensure that problems are addressed before proceeding to vehicle tests. This paper reports testing of the prototype brake on a such a dynamometer. The prototype brake itself is first briefly described, including the main instrumentation used during the tests. This followed by a short section detailing the capabilities of the dynamometer.
