ETAS innovations on the Stuttgart Symposium

On March 18-19, 2014, over 800 vehicle developers will come together for the Stuttgart International Symposium "Automotive and Engine Technology". ETAS is giving no less than four specialist lectures at Europe’s leading innovation forum.

There’s no doubt about it: automotive and engine technology is becoming more complex with each new generation of vehicles to come to market – and this is driven just as much by emissions legislation and ambitious climate protection objectives as it is by increasing demands in terms of vehicle safety and connectivity.

If they want to keep on top of this complexity in the face of increasingly short development cycles, vehicle developers need well thought out IT tools and concepts that have been tested and verified. These are precisely the focus of four presentations that ETAS specialists will be giving at the 14th Stuttgart Symposium “Automotive and Engine Technology.”

  • Burkhard Triess, Director Engineering Technology Hardware at ETAS GmbH, will illustrate ways in which Ethernet on-board systems with distributed domain control units can be kept real-time capable in future despite swelling data rates. The key to this is the new ETAS Data Engine (EDE). It relieves control units of the torrent of communication tasks that rain down on them up to two orders of magnitude faster via Gigabit Ethernet than via CAN networks. EDE is a hardware-based data transfer point that is able to minimize latencies and jitter especially in complex on-board systems that have different communication standards. This is the prerequisite for ensuring that safety-critical data from environmental sensors and in-vehicle sensors can continue to be processed at speeds measured in microseconds. ETAS is currently working together with Bosch to prepare EDE for inclusion in series production of next-generation on-board systems.
  • Thorsten Huber, Product Manager for the ETAS ASCMO tool suite, will be demonstrating just how precisely emission values for complex turbocharged diesel motors with cooled exhaust gas recirculation can be predicted using simulation methods. Particularly with a view to the upcoming transition from the NEDC to the more dynamic WLTP driving cycle and increasingly stringent emission limits, engine developers will have to have reliable simulation tools at their disposal to help them ascertain the effect that modifications to engine hardware and ECU data have on nitrogen oxide and particulate emissions when driving. Thorsten Huber will introduce a solution based on the ETAS ASCMO tool that builds on leading simulation software products (Simulink, GT-Power) by supplementing their traditional, physically based modeling systems with an additional high-speed, highly precise data-based system level. Validation tests prove that emission predictions are remarkably precise.
  • Dr. Corina Mitrohin, a computer scientist from ETAS GmbH‘s Advance Engineering department, is giving an expert paper entitled “Powertrain co-simulation on top of standards“ in which she introduces how to move beyond today’s thicket of IT engine development tools, which arose as a result of historic and technological factors. By consistently orienting themselves toward existing standards such as Automotive Software Architecture (AUTOSAR) or Functional Mockup Interface (FMI), developers can overcome the system-related gulfs that open up during the largely decoupled development phases involved in in-the-loop processes (model, software or hardware in the loop).
  • Fuel-cell drive developers also require reliable modeling methods. In his lecture on “Modular modeling of a PEM fuel cell system for automotive applications” Raphael Hans will be presenting a modeling solution developed by ETAS GmbH in collaboration with researchers from the University of Stuttgart and from Esslingen University of Applied Sciences. Hans, who heads up this development for ETAS Test System Engineering, will introduce the modular simulation tool that packs PEM technology and its associated complex supply periphery into a mathematical model, thereby providing developers with a highly sensitive tool for configuring fuel-cell drives.
