Dynamic reconfiguration for high level in-vehicle applications using IEEE-1394

In recent years, networking issues have become more and more important in the design of vehicle control systems and driver assistance functions. We present a pragmatic approach for validating real-time in-vehicle applications using IEEE-1394 bus. By validation, we mean the verification of real-time constraints that is met by the automotive applications. We describe how the IEEE-1394 standard can respond to hard real-time constraints of critical and non-critical applications. We then present a software architecture based on distributed calculators interconnected by IEEE-1394 bus and well adapted for integrating multi-sensors automotive applications.
