A mechatronic CAN-based functional design and verification unified approach

Abstract

A mechatronic system needs an integrated design, implementation and verification unified approach due to multi-disciplinary interactive sub-system components. This paper presents a systematic methodology for a detailed migration from "model in the loop" (MIL), and "software in the loop" (SIL) to "hardware in the loop" (HIL) in order to full fill complicated mechatronic automotive system requirements. Break by wire anti-blocking car system model is implemented and simulated on Matlab™ in real time. For MIL, and SIL a virtual CAN bus channel is designed in order to communicate sensors and actuators signals to/from several electronic control units (ECUs). HIL is implemented to experiment the actual embedded controller performance over a real CAN bus with the real time simulated car model. Both virtual and real experimental results show the efficiency of the proposed approach. Copyright © 2007 International Federation of Automatic Control.
