• Growing Complexity in the Powertrain

    The conventional internal combustion engine is facing increasing pressure. Driving bans are being discussed for more and more inner cities and 2017 may see the introduction of the blue (nitrogen oxide) badge. A further challenge to developers are Real Driving Emissions (RDE) and the new Worldwide Harmonized Light-Duty Vehicles Test Procedure (WLTP). In future, vehicles will be required to meet even tighter CO2 and emission limits (...). More

  • Model-Assisted Calibration Meets Future RDE Requirements

    When real driving emissions (RDE) are crucial to approving vehicles in less than two years, the work of the calibrators will become even more challenging: Then they must ensure robust calibration that reliably meets the limit values for different traffic conditions, journeys and driving styles. IAV has developed a process for this that is based on modeling the whole vehicle, delivers precise, reproducible results and noticeably (...). More

    Model-Assisted Calibration Meets Future RDE Requirements
  • Reliably Meeting Future RDE Limits

    Unlike test cycles, such as NEDC or WLTC, measurements based on real driving emissions (RDE) prescribe no set speed-load profiles. The vehicle still has to meet the average emission limits of the WLTC. IAV is addressing this new challenge with additional software control layers: The emission coordinator sets targets for engine control and exhaust gas aftertreatment control, making sure that the demanded real driving emissions are (...).

  • Life Cycle Assessment to Evaluate Technology

    From producing raw materials to recycling: To compute a vehicle’s ecological consequences in a life cycle assessment (LCA), IAV’s experts need to look at the entire product life cycle. Ever more challenging statutory requirements are increasingly moving the subject into the focus. Dr Bernd Becker, head of department Vehicle energy management explains in the interview how IAV draws up life cycle assessment.Dr Becker, what makes (...). More

    Life Cycle Assessment to Evaluate Technology
  • Looking at the Full Picture for a Fair Comparison

    What impact does a vehicle with a specific powertrain have on the environment? To date, this has mostly involved looking at the emissions produced while driving. Yet this approach does not go far enough: The life cycle assessment (LCA) shows that while the vehicle is used, attention also needs to be focused on the provision of fuel and also on the process of manufacturing and recycling vehicles. Increasingly, results of this type (...). More

  • Over 1,000 Kilometers on One Battery Charge

    The battery is a key component in deciding the success of e-vehicles. This is why manufacturers have set themselves ambitious targets: They want to double the energy density from currently around 250 watt hours per liter (Wh/l) to 500 Wh/l. At the same time, production costs are to fall well below € 200 per kilowatt hour. Within the "ePadFab” research project, IAV is working with partners thyssenkrupp System Engineering and (...). More

  • A Suite for All Eventualities

    Both IAV Engine and IAV Engine Toolbox are integrated tools for developing and optimizing mechanical engine systems. With IAV Engine being so fast, numerous options can be simultanously examined and interactively compared. Particularly at the early stages of the development process, the tool’s easy-to-parameterize models provide important information – such as estimating potentials. IAV Engine Toolbox is used as a portal to IAV (...). More

    A Suite for All Eventualities
  • Focus on Thermal Flow

    High amperages and some confined packages: During operation, high-voltage cables in hybrid and electric vehicles can get very hot if their cross sections are too small. On the other hand, over-dimensioned cables incur unnecessary costs and increase vehicle weight. IAV’s THS (Thermal Harness Simulation) tool computes the buildup of heat during subsequent operation and helps to select the optimum cable cross section.Around 15 (...). More

  • Automated Testing for the Release of Software Updates

    It is necessary to perform and evaluate many measurements to introduce new engine software or a new data record or to release production statuses for passenger car gasoline engines. One of the challenges here lies in the growing complexity of interconnected systems and increasing vehicle variance. On the other hand, shorter development cycles and scarce resources are leading to a shallower depth of validation. Particularly for (...). More

    Automated Testing for the Release of Software Updates
  • Maximum Voltage, Maximum Safety

    With their high-performance high-voltage batteries, hybrid and electric vehicles could also supply external power consumers. However, handling 400 volts is somewhat more complicated than connecting up to the 12-volt vehicle electric system through the cigarette lighter. This is why IAV has developed flexPi: The universal high-voltage interface for the vehicle is not only safe but also bidirectional – and, among other things, (...). More

  • Making Optimum Use of Wind Power

    Even today, wind energy is a key pillar in our energy supply. And with the industry growing all the time, there is an increasing demand for first-class engineering. On top of this, there are many parallels with automotive engineering, e.g. in control technology. This is why IAV is stepping up its involvement in this segment – with a booth at the “WindEnergy” expo in fall at Hamburg, for example. The aim is to industrialize (...). More

    Making Optimum Use of Wind Power
  • Indispensable for System Optimization

    A lot is going on in commercial applications: New powertrains, higher efficiency auxiliaries or digitization are opening up new ways for developers to optimize products. Exploiting this potential to the full involves detailed simulation of entire systems, such as commercial vehicles or mobile machines. To this end, IAV uses its proprietary Velodyn for ComApps tool throughout the development process.What does the optimum powertrain (...). More

    Indispensable for System Optimization
  • From Computation to Operating Strategy

    These are no easy times for power grid operators: It is all about constantly optimizing grid management. At the same time, the regulated providers must integrate decentralized and fluctuating power producers into their infrastructure. This, along with automation, demands huge investment, with boundary conditions changing all the time. Harmonization of the grids for electricity, gas and heat is also on the agenda (sector coupling). (...). More

    From Computation to Operating Strategy
  • Transferring Technology to Promote the Energy Transition

    Renewable energy harvested from wind or the sun fluctuates widely and cannot be matched to today’s power consumption. For this reason, intermediate storage systems will be needed in future that reconcile supply with demand. This is where hydrogen lends itself as an energy carrier. IAV has teamed up with partners to work on an alkaline water electrolyzer with an output of 100 kilowatts that is to benefit from automotive (...). More
