instrumentation & test systems USING AVL CRETA 4™ FOR CHASSIS DEVELOPMENT AT PORSCHE Reliable processes and efficient calibration data management allow Porsche engineers to focus on what matters most: ensuring that control systems are optimally tuned for a truly unique sports car experience. Racing track performance and long-haul comfort – Porsche developers have mastered this balancing act by integrating cutting-edge electronic control systems into a perfectly tuned mechanical chassis. In the past years, for instance, purely passive components were successively replaced by active and semi-active systems. Examples for this trend are active rear steering, electronic shock absorber adjustment or active anti 2 6 F O C U S roll control, to name but a few. Whether or not these technologies can reach their full potential within the vehicle lastly depends on the way the control units are calibrated. The system behavior is precisely tuned to every available vehicle variant by establishing the optimal value for all control unit parameters. In doing so, every single vehicle version receives its very own electro- nic DNA – a tremendous effort for the sports car manufacturer which is known for its broad variant diversity. In the course of development, massive volumes of calibration data are generated, and the engineers must ensure that only the best possible parameter settings find their way into the series vehicle. For this purpose, the work accomplished by the various calibration teams, each responsible for one control unit, is
