An Introduction to an Embedded Automotive Solution, Nucleus OSEK

OSEK/VDX is a joint project of the automotive industry. It aims for an industry standard of an open-ended architecture for distributed units in vehicles. A real-time operating system, software interfaces and functions for communication and network management tasks are thus jointly specified. The term OSEK means open systems and the corresponding interfaces for automotive electronics. This particular standard originated in Germany, and included BMW, Bosch, Daimler-Benz, Opel, Siemens, VW, and the IIIT of the University of Karlsruhe. The term VDX means "Vehicle Distributed eXecutive." This standard originated in France and included PSA and Renault. The functionality of the OSEK operating system was harmonized with VDX. For simplicity, OSEK will be used instead of OSEK/VDX. Part of the motivation behind the development of OSEK requirements was high, recurrent expenses in development, irregular management of non-application related aspects of control unit software, and the incompatibility of control units made by different manufacturers due to different software interfaces and protocols.
