1 5 F O C U S ers expert advice, we need to analyze and understand the complete vehicle and its application. No matter how good the built-in vehicle components are, if they are not optimally tuned to the application, their potential will remain unrecognized. That is why here at AVL, we use both our in-depth component know-how and our system knowledge to design and integrate them into the overall system in the best possible way.” CO2 EMISSIONS LEGISLATION – LIMITS AND ZERO EMISSIONS In markets like the U.S., Japan or China, the CO2 emission regulations are already in force in their first phase, and in Europe legislation proposals are in their evaluation phase. So with regard to the CO2 limits, which are in the process of gradual decrease, overall system analysis will be a crucial factor in goal-oriented technology selection. This is because, depending on the application and vehicle class, optimized conventional, hybrid and fully electric powertrain technologies will be used. “ATTRIBUTE BALANCING” FOR OPTIMUM BALANCE OF VEHICLE CHARACTERISTICS The newly developed method of “attribute balancing” enables the definition of the optimal technology mix for a certain vehicle class and application regarding the required targets. In the world of commercial vehicles “optimal” means achieving performance targets with a successful business case enabled with the lowest possible development- and product costs. Base Vehicle Cost Reliability Productivity SIMULATION FOR A BROAD VARIANT DIVERSITY To evaluate the relevant overall system optimization technologies in the context of attribute balancing, and to develop concrete concepts including their attributes, AVL works with state-of-the-art simulation tools such as AVL-DRIVE™, AVL CRUISE™, AVL VSM™ or AVL EXCITE™. As Gernot Hasenbichler explained, “These tools allow you to rate the different targets and attributes already in the virtual world, and work out the best match of technologies and their configuration for the application.” TECHNOLOGY TRENDS Given the increasingly stringent exhaust emission regulations, the experts at AVL are certain about where the future technology trends in the commercial vehicle industry are heading: Electrification will for sure find its way into most of the Performance Attributes markets. Depending on the application, different degrees of electrification will be implemented. Electrified auxiliaries are expected to catch on in most markets, with full hybrids and electric vehicles being operated in urban areas due to local legislations and zero emission zones. Particularly in the field of long-distance transport, however, the optimization of the internal combustion engine and the conventional powertrain will remain a central challenge. AVL OUTLOOK ON SYSTEM OPTIMIZATION IN COMMERCIAL VEHICLES The system development for commercial vehicles combined with its tools and detailed knowledge of the five powertrain components give AVL a strong unique selling point. The next step will be to gradually roll out these fields of expertise and services globally – beginning with benchmarking and “attribute balancing” up to the integration of conventional, hybrid and fully electric powertrains in vehicles. < > Attribute Balancing for the optimal technology mix.
