Industrial Panel: Automotive – Green Mobility

In appreciation of the strong connection and interaction between industry and academia in Austria, the program of ECC15 will feature two dedicated industrial panel sessions. These sessions are organized by the Industry Chairs and focus on the topics of Green Mobility and Clean Process Industry. Each session is composed of three expert talks and an open panel discussion, where the speakers will provide insights in current and upcoming challenges. Both sessions are scheduled in the afternoon tracks of ECC15 and are open for the public.

Real-time Co-Simulation – Challenges and Applications

Speaker: Dr. Josef Zehetner
Company: IODP System Architecture Management, AVL List GmbH

Abstract: The term "system of systems" refers to a class of complex entities which offer more functionality and performance than simply the sum of their constituent components. A typical property is the separation into various subsystems from different physical domains and the strong interdependency of these. Examples are power networks or mechatronic units linked via communication networks, as it is the case in modern vehicles or industrial plants like paper-machines.

For the virtual development of such systems the coupling of domain specific simulations tools via "co-simulation" is a suitable and necessary approach. Nevertheless, when real hardware comes into play, the links to traditional proving methods like hardware-in-the-loop testbeds are challenging due to the specific requirements of the so-called hard real-time systems.

This presentation gives an insight into challenges for the engineer and shows possible solutions and applications when extending co-simulation into the real-time domain.

Efficient Control Design and Application with Co-Simulation and the FMI standard
Speaker: DI Thies Filler
Company: Volkswagen AG, Wolfsburg, Deutschland

Abstract: Simulation based design and evaluation of vehicles become more and more important due to the increasing complexity of technical systems in the vehicle as well as to the continuously decreasing development time. Simultaneously, the complexities of control systems increase constantly. For this reason, the simulation based control design becomes more and more important. Further the study of interaction of different components (e.g. engine, coolant circuit) and their control strategies plays an increasing role in simulation.

Simulations are used to evaluate control algorithms at early stages of development. Furthermore a coupled simulation provides the opportunity to regard interdependencies of controller algorithms. Therefore a co-simulation offers the opportunity to support efficient control design and analysis of complex control systems. The complex heterogeneous landscape of different modeling tools, different technical models as well as a great number of shared persons makes a comprehensive use of calculation models difficult. Only through a standardized model format this complexity becomes controllable. The FMI standard (Functional Mock-up Interface) was developed for a uniform and secure model exchange. FMI is a tool-independent standard with a uniform description of calculation models. This standard includes the coupling interfaces next to the model equations. The calculation of the coupled system is managed via a co-simulation environment, which takes over the control and the synchronization of all FMI models.

In the presentation, possible application of efficient control design and application of control code with co-simulation and the FMI standard will be demonstrated. Applications with focus on driving dynamics and vehicle air-conditioning will be presented.
