The application of based on model embedded software for automotive electronic throttle

This paper presents a mode-based approach to the design of embedded real time control software.The principle of this approach is that high level models,which are most commonly used for simulation,are extended to simulate the software and serve as the implementation,from which the executable code for the embedded target is generated.The basic elements of real time embedded control system software include: FSM,tasks,schedulers,control flow,data flow.The electronic throttle control system is typical application system of real time embedded software,.It is limited by cost and the requirement of high safety and reliability,is suitable for model-driven frame software design.
