powertrain engineering To meet the increasing global transportation demands combined with lower fuel consumption and lower emissions, it is essential to optimize the system holistically. AVL has development tools and experts needed for the optimization of complete commercial vehicles systems. COMPLETE SYSTEM OPTIMIZATION ENHANCES EFFICIENCY IN COMMERCIAL 1 4 F O C U S VEHICLES BENCHMARKS SERVE AS OBJECTIVE BASIS FOR POSITIONING In benchmarking different vehicles are measured in detail and rated to determine values for their levels of performance, drivability, fuel economy and emissions. AVL-DRIVE™ assesses performance (including drivability) as well as efficiency and emissions. Even the performance attributes receive an objective description. This is done by comparing the vehicles with current truck data using so-called scatter bands. The target values are described objectively and the necessary improvements are precisely specified as system requirements. Gerhard Stempfer, Head of Commercial Vehicle System Development, explained: “Having defined the targets for a complete system optimization, we derive the individual component requirements and work out how they can be optimally tuned.” ANALYZING VEHICLES AS COMPLETE SYSTEMS Gernot Hasenbichler, Product Manager Commercial Vehicle On-Road, explained further: “Many years ago, we recognized that it wasn’t really possible to view axle, transmission, electrical components, software and the internal combustion engine separately. To be able to give our custom- > Achieving goals with in-depth component know-how and system knowledge.
