Model-based design and analysis of automotive systems using time-triggered controller area networks.

摘要

As the number of electrical components vastly increasing within a modern motor vehicle, the electrical failure caused vehicle recall has become an issue for both car manufactures and customers. This paper will focus on discussion of a method to assist designers analysis the TTCAN (Time-Triggered Controller Area Network) bus in post-design phase and give further discussion about a general analysis/testing method for embedded system design. In this research we use program from UTA FSAE racing car as study example; the model will include a master controller's code and two wing controller's code. This research will transplant the origin C program onto Simulink/Stateflow (SLSF) environment, each function/task is hooked up by a Stateflow chart. Furthermore, for any general design concept analysis this method could be used.
