A model-based design for electronic control units based on OSEK/VDX

Control system embedded software is steadily increasing in size and sophistication, because of the complexity of the hardware and environmental interfaces associated with it. Control algorithms are now more complex and require more time and cost to implement that real control systems. This paper presents a method of developing electronic control units (ECUs) based on OSEK-VDX using model-based design and an embedded system platform. We develop a platform for ECUs in a vehicle as a real target system which plays the role of a universal ECU. The model based design is achieved by Matlab/Simulink. Using this method, it is possible to quickly implement embedded software including complex control algorithms without the time and cost burden associated with understanding hardware and software engineering.
