Analysis of implementing OSEK NM with two types of ECU network

ldquoOpen Systems and their interfaces to electronics in Motor Vehiclesrdquo (OSEK) is a real-time operating system used in vehicle systems. OSEK is a standard operating system used by many carmakers. OSEK has a network management algorithm, OSEK network management (OSEK NM). It has two management rules: Direct NM and Indirect NM. Direct NM and Indirect NM are implemented in two network protocols for ECUs, CAN and LIN. Their advantages and disadvantages are analyzed. When two OSEK NM management rules are applied to the communication protocols, application problems and differences could be found. Performance analysis in real applications and network management rules for each network protocol are proposed.
