1. Working Group “Real-Driving Emissions of Light-Duty Vehicles” Work Progress – December 2011

2. Objectives (Reminder)
To conduct a technical assessment of the proposed candidate procedures
To develop a RDE-LDV procedure complementing the future main type approval cycle
To disseminate the know-how regarding the procedures
To contribute to legislation drafting (e.g. test protocol)
Data evaluation is one of the key points and differs a lot from the US approach (the US-NTE method)
Keep in mind that the experiments are run in the same way in the US and in the EU but the data is evaluated in a completely different way
(READ)
Another important point to keep in mind is that the method is able to deal with difficult cases.
The best example is a city bus test, which you CAN evaluate with the EU moving averaging window and NOT with the US-NTE
Another example is given on the next slide. 2
