The vehicle of the future is driven by strong market demands for minimum emissions and optimized fuel consumption as well as maximum driving fun within an increasingly dynamic and complex system and user environment. New technologies evolve at an ever faster pace to tackle these changing market needs and meet new legislative emissions targets. The variety of solutions for the new electrified powertrain pose extreme challenges with respect to the best integra-tion of the increasing number of hybrid subsystems. How do the conventional combustion engine, electric motor, battery and hybrid control strategy interact in the diverse situations of real-life vehicle usage? These questions cannot be addressed at the end of the vehicle development process, but ideally at very early stages to develop each subsystem with its later integrated real-life usage in mind. Therefore, anticipating real-life driving conditions and their immediate impacts on overall vehicle performance is one of the key factors of success in the develop-ment of future drive systems. The need to pursue developments in all the test environments in a realistic fashion coupled with the increasing need to cut cost-intensive development times require capturing and mapping of the real environ-ment-system-user interaction and making it continuously available throughout the entire development process. Of the different test environments, the testbed as the interface between the real and virtual environments plays an essential role

The other option for gaining rel-evant data is real-life testing with AVL M.O.V.E. Used complementarily, both approaches offer the best results in maneuver-based testing.

in the development process. Simulation data are in-tegrated on the testbed, testbed results are verified on the road, and real-world results returned to the testbeds. In order to seamlessly integrate the varied reality of everyday driving operation into the testbed from the earliest possible phase of the development process, different paths can be taken. On the one

As OEM product lines keep expanding and the va-riety of hybrid test systems on the market increases steadily, development teams rely on simulation-based testing to enhance process efficiency by transferring testing tasks from the expensive physical proving ground to the virtual proving ground. Improved development quality and produc-tivity gains can be realized by utilizing simulation tools that anticipate drive system integration under simulated real-life conditions and allow for continu-ous improvement of simulation results throughout the entire development process.

AVL InMotion bundles the vast hybrid system integration know-how of AVL in one integrated real-life simulation platform. It allows the simulation of single hybrid subsystems including their inte- grating control strategy and anticipates how the entire vehicle would behave under typical real-life user conditions and individual driver maneuvers. Real-life driving maneuvers, simulation data and validated testing results are shared in all automotive testing stages to enable simulation model improve-ment and learning throughout the development

Applications

hybrid TestingElectrification is changing the automotive industry. AVL InMotion keeps three factors at the forefront: quality, cost reduction and time to market.

Real World Fuel Economy Testing Reducing CO2 emissions is today perhaps the most important issue for OEMs and TIER1s. AVL InMotion brings the real world to the testbed. Test engineers appreciate the efficiency and speed with which concepts can now be evaluated and turned into tangible products.

Virtual proving ground Testing The test engineer has the capability to perform

corporate test procedures in a reliable virtual prototype environment in place of or prior to more expensive experimentation on the physical proving ground. The task is to map the corporate maneuver catalogue to the testbed. Consider the possibilities instead of the limitations: city driving, handling, par-allel parking, handbrake U-turns and jump starts.

Consumer Report Testing Car manufacturers can now take advantage of AVL’s real-life approach and test drive their products on the Nürburgring, France Route, Schwarzwald-runde or “auto motor und sport-Verbrauchsrunde” upfront – and before the journalists get there – on the testbed. Lean and mean, fast and cheap. Preconfigured digitized 3D benchmark roads, tires and virtual prototype cars allow engineers to hit the ground running.

powertrain Misuse Testing Handbrake U-turns, bootleg turns, left-foot bra-king maneuvers, drifting, clutch kicking, bumping and jumping. Key components of these tests are leading-edge real-time virtual prototype models.
