The program portfolio offers transmission and entire driveline modeling capabilities on all the required levels. It answers the needs of diverse applications in component and control development and vehicle integration, from general system behavior to detailed analysis of losses to NVH and durability of single components. EFFICIENCY ENHANCEMENT – UNDERSTANDING COMPONENTS AND SYSTEMS When searching for energy saving potential in already extensively optimized drivelines, a primarily component-focused approach, which was standard and normally sufficient in the past, is no longer appropriate. The entire energy flow from drive power generation to the power at the wheel needs to be investigated, taking into account the loss contribution of each component to vehicle CO2 emissions. This requires a comprehensive systematic approach with an integrated subsystem and detailed component investigation. Using AVL EXCITE, component and subsystem analyses are performed in order to derive friction maps for each of the loss-contributing parts. These maps are then used in AVL CRUISE for vehicle system investigation, such as the power flow and loss distribution analysis during drive cycle tests. This type of tool interaction makes it possible to understand the impact of each component as well as its modifications on vehicle fuel efficiency which in turn allows one to invest in component improvements with the highest cost/benefit ratio.
