instrumentation & test systems input. CAMEO has the ability to perform automatized optimization, not only focused on a defined cycle, but on a multitude of different drive cycles. Apart from that, the new Emission Predictor allows you to check a broad range of variants and driving situations. This is of tremendous importance, as our customers, from a purely theoretical point of view, have to handle RDE optimization for an infinite number of driving situations. The goal is always to achieve lower consumption levels while maintaining the RDE limits and ensuring good driveability,” Hans-Michael Koegeler explains. But how can one transfer the ‘randomness’ 1 6 F O C U S associated with RDE with regard to driver behavior, driving environment or the surrounding traffic to the engine or powertrain testbed or to the chassis dyno? Here, too, the M.O.V.E iS system is able to provide a valuable service, Roland Wanker explains: “With M.O.V.E iS, you are able to go on test drives in which all of the geographical data, including the elevation profile, are captured for each driving situation with very high precision. Added to this are climate data – temperature, air humidity, etc. – and, of course, all data concerning the vehicle dynamics, from the steering angle to the speed of each of the four wheels. To be able to clearly identify specific driving situations afterwards, for example an overtaking maneuver, there is even a video system.” For development in conventional testing environments, such as engine or powertrain testbeds or chassis dynos, RDE presents a major challenge. Keeping its focus on RDE, AVL has taken the “Real Life Testing” idea to the next level and has identified the following use cases for development: • Exact reproduction of driving situations: to be able to reproduce and solve a problem at an exactly defined point, for example, AVL has developed new control algorithms for chassis dynos. • Virtual integration of components and variations of situations and peripheral conditions: by using the simulation platform AVL InMotion, it becomes possible to recreate the road virtually on the test bedfor “Real Life Testing” and replay the drive virtually under any conditions you require. • RDE reference cycles: having the ability to compare the results between different vehicles and development stages is crucial to the development process. For this purpose, AVL develops and optimizes RDE reference cycles for vehicle classes. EASE OF USE AND CONSISTENT DATA MANAGEMENT As with all of AVL’s new development methodologies and tools, ease of use is always at the foreground. AVL XIL.STATION, AVL’s virtual engine testbed, for example, allows you to perform pre-calibrations based on models, and gives calibration engineers exactly the same tools and user interface they are familiar with from the real engine testbed. Besides focusing on easy operation, significant effort was put into ensuring that the models are easy to handle too. “Similar to putting an engine into operation on the testbed, an engine model has to be ‘set up’ and started up on the XIL.STATION too.
