/ 91 Vehicle Testbeds for Advanced Calibration Applications AVL offers integrated solutions for calibration tasks on vehicle testbeds. These are composed of the required testbed system, the attuned software solutions and the related methodological support. CHARACTERISTICS The process of networking in AVL ROADSIM, AVL PUMA Open for Vehicle Testing, AVL CAMEO™ and AVL ACT results in a flexible and powerful overall solution. During this process, the vehicle testbed is responsible for an exact modeling of the road. On one hand, the automation allows for automatic operation of the test specimen and, on the other hand, it allows for a quick change-over between different reproducible operating statuses due to the close coupling with the controlled testbed. Besides controlling the test, AVL CAMEO™ is integrated across test planning and analysis, including model formation, optimization and map calculator. An ASAP 3 interface can be used to transfer the drivability-relevant control unit variables to the application system. Ultimately, the driving maneuvers are evaluated and physical parameters and marks are determined. For example the signal of a load cell is designed as an indicator of longitudinal vehicle acceleration, where this load cell is integrated into a special vehicle support. APPLICATION This solution is used for engine, transmission and overall powertrain calibration. Time- and cost-intensive road tests can largely be shifted to the vehicle testbed. On the basis of the model-based approach, only the determined vehicle adjustment afterwards must be verified on the road. Adjustments with different objectives, such as comfort and dynamics, are easily implementable. Automated calibration on the vehicle testbed BENEFITS AT A GLANCE • Highly precise and dynamic road load and simulation for the highest requirements especially in (driveability) calibration • Integration of established tools for optimization and drivability evaluation • High efficiency due to automated operation at night • Excellent reproducibility and transferability between real road and vehicle testbed • Visualization of completely embedded driving cycles for calibration (e.g. consideration of the parameters for altitude, incline, air conditioning system and further maneuver-based factors)
