Sponsoring organization Title and subtitle Investigation of Real-Time Operating Systems: OSEK/VDX and Rubus (Analys av realtidsoperativsystem: OSEK/VDX and Rubus) The aim of this work was to investigate the possibilities and consequences for Haldex Traction of starting to use the OSEK/VDX standard for realtime operating systems. This report contains a summary of the realtime operating system documents produced by OSEK/VDX. OSEK/VDX is a committee that produces standards for realtime operating systems in the European vehicle industry. The report also contains a market evaluation of different OSEK/VDX realtime operating systems. The main differences between OSEK/VDX OS and a realtime operating system named Rubus OS are also discussed. There is a design suggestion of how to change an application that runs under Rubus OS to make it work with an OSEK/VDX OS. Finally a test of changing a small test application’s realtime operating system from Rubus OS to the OSEK OS osCAN is presented
