The main drivers of today's automotive applications are the reductions of ECU systems cost as well as the development of new innovative functions such as: perceived vehicle performances, active vehicle safety, new emission laws (EU5, EU6) and CO2 reduction. On the other hand more and more resources are spent on adapting the Intellectual Properties (IP's) control solutions to different electronic control unit eroding precious time for the development and validation of the project. To match challenging Time to Market constraints (less than 18 months for a new application) versus Automotive functions complexity increasing, without sacrificing system quality and robustness, a new approach appears unavoidable, perhaps a change of paradigm, where relationships and cooperation between Original Equipment Manufacturer (OEMs) and Suppliers as well as Supplier to Supplier interfacing have to evolve into a new model for both development and commercial issues. This emerging scenario has been taken into account by the AUTOSAR (AUTomotive Open System ARchitecture) consortium defining technologies and process in order to permit to share SW IP's over different platforms and applications. This paper describes, using a real example of a mechatronic scalable control IP's, developed with model based approach technique and configurable on different applications using the AUTOSAR technology, the approach followed by Magneti Marelli (MM) to play the new roles of SW IP's supplier and SW IP's integrator.
