Graphical modeling and code generation for distributed automotive control systems

This paper describes how a specific modeling tool, MATRIXx, from Integrated Systems, Inc., can be applied to rapidly develop automotive control software for a family of rapid prototype controllers from Motorolas Automotive Industrial Electronics Group. The work described shows how the modeling tool can be used to specify communication between the distributed controllers using CAN and J1850 standards. In addition to supporting communications interfaces, the modeling tools and controller hardware also support additional advanced features, such as low-power operating modes, storing and moving data to and from non-volatile memory, and also interfacing to sophisticated automotive calibration tools. Finally, the application of these hardware and software development tools to an automotive system are described along with ways that these tools can reduce control system deployment time.
