These are composed of the required testbed system, the attuned software solutions and the related methodological support. CHARACTERISTICS The networking of AVL ROADSIM, AVL PUMA Open Vehicle Testing, AVL CAMEO™ and AVL ACD results in a flexible and powerful overall solution. This means the vehicle testbed provides exact modeling of the road. On the one hand, the automation allows automatic operation of the test specimen and, on the other quick change-over between different reproducible operating statuses. 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 driveability-relevant control unit variables to the application system. Ultimately, the driving maneuvers are evaluated and physical parameters and marks are determined. The signal of a load cell is, for example, 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 relocated to the vehicle testbed. Thanks to the model-based approach, only the determined vehicle adjustment has to be verified on the road afterwards. Adjustments with different objectives, such as comfort and dynamics, can easily be implemented. BENEFITS AT A GLANCE • Highly precise and dynamic road load simulation to meet with the highest requirements especially in (driveability) calibration • Integration of established tools for optimization and driveability evaluation • High efficiency due to automated operation at night and on weekends • 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 Advanced Calibration for Driveability on the vehicle testbed factors)
