The goal is clearly defined: A vehicle must pass an RDE assessment during its entire service life in the market with a 95-percent probability.” The huge increase in the number of cycles, in which the predicted outputs (example: co2) 1 7 F O C U S VARIATION 1 VARIATION 2 procedures for model handling, making virtual development even easier for users,” the expert says. According to Hans-Michael Koegeler, the topic of real driving emissions is also adding importance to tried and tested calibration tools: “The CRETA calibration data management software gives you the ability to ensure consistent database management for control unit parameters across all testing environments. Since reliability is also a relevant factor for simulation models that are used in a variety of development environments, initial projects are currently underway in which CRETA is also being used to manage simulation model databases. To achieve development results comparable across the globe, our customers also value standardized calibration procedures. These are supported CO2 HC NOx CARBON DIOXIDES FUEL CONSUMPTION SMOKE HYDROCARBONS NITROGEN OXIDES vehicle’s emission behavior has to be tested for RDE, has made it essential to adapt processes Hans- Michael Koegeler points out. “Also due to our tremendous experience in the area of heavy-duty vehicles, where RDE has been a topic for quite some time, we have seen some successful examples of how our customers have adapted their processes to fit the new requirements and successfully developed them further by harnessing the new possibilities. Key elements in an efficient RDE development process are in my opinion model-based frontloading and model-based calibration, particularly in view of the increasing diversity of variants. The key to success is efficient optimization, consistent across all development environments and standardized for all locations around the globe.” < Engine output Engine output map Driving cycle engine maps inputs measured driving cycle data cameo model Value 1 Value 2 etc Driving cycle input Value 1 Value 2 etc Value 1 Value 2 etc Value 1 Value 2 etc CO2 Value 1 Value 2 etc Value 1 Value 2 etc CONVERTER TORQUE SPEED INJECTED FUEL MASS VEHICLE SPEED CARBON DIOXIDES (etc) > The new CAMEO Emission Predictor allows the validation of a certain calibration for any driving cycles.
