RAPID CONTROL PROTOTYPING FOR AUTOMOTIVE SOFTWARE IN POWER WINDOWS SYSTEMS

Current and next generations of passenger and commercial vehicles have functions with increasingly higher levels of complexity. The traditional methodologies of software development are not robust enough to meet the requirements for current vehicle systems. Modern features and functions must provide improved properties in terms of drivability, safety, comfort and performance, and also additional features, such as driver assistance and connectivity. In order to address those challenges, new development methodologies and standards for automotive embedded systems are necessary to ensure the correct process for all phases of the automotive software engineering, from development to production. Model-based design (MBD) methodology represents a key methodology which may satisfy those demands of automotive software development. It considers that the first step is to define the requirements based in the physical plant simulated, followed by the development of the controller, and then a set of test cases are performed with the controller, to validate the initial requirements. The first stage of MBD, model-in-the-loop, is presented for the power window function of an automotive system.
