Efficient Monitoring of Real Driving Emissions

2018
The diesel emissions scandal has demonstrated that real-world behavior of systems can deviate excessively from the behavior shown under certification conditions. In response to the massive revelation of fraudulent behavior programmed inside diesel cars across Europe, the European Union has defined a procedure to test for Real Driving Emissions (RDE ...

Condensation of Real-World Drive Cycle into Synthetic Drive Cycle - An Innovative Method to Predict Real Driving Emissions

SAE Technical Paper Series, 2021
<div class="section abstract"><div class="htmlview paragraph">The stringent emission regulations have put enormous pressure on auto manufacturers to develop vehicles with the required conformity factor (CF) on real driving emissions (RDE). However, evaluation of CF on multiple and varying real-world cycles by portable emission measurement ...

vRDE – Virtual Real Driving Emission

2017
Die Verbrauchs- und Emissionszertifizierung anhand des NEFZ stand bis zuletzt, nicht nur im Zusammenhang mit den sogenannten „Defeat Devices“, in scharfer Kritik – 2017 soll mit der Einfuhrung von WLTP und RDE genau diese Problematik aufgegriffen werden. Europa ubernimmt damit eine Pionierrolle auf dem Gebiet der Emissionsgesetzgebung.

Questions about Real Driving Emissions in Brazil

SAE Technical Paper Series, 2017
<div class="section abstract"><div class="htmlview paragraph">The motor vehicles are the main source of atmospheric pollution, especially carbon monoxide, hydrocarbons and nitrogen oxides (NOx). To reduce these emissions for environmentally acceptable levels, Europe and the United States have developed control programs, where are set ...

Testing and evaluation of cold-start emissions in a real driving emissions test

Transportation Research Part D: Transport and Environment, 2020
Abstract To properly evaluate the cold-start emissions of vehicles, four light-duty vehicles were selected to complete a Real Driving Emissions (RDE) test. The analysis and evaluation of the RDE test results reveal that the cold-start emissions account for a significant proportion of the urban trip emissions, and that the moving average window (MAW ...

Some Repeatability and Reproducibility Issues in Real Driving Emission Tests

SAE Technical Paper Series, 2018
<div class="section abstract"><div class="htmlview paragraph">The new European Commission Regulations for vehicle certification include a new laboratory procedure for fuel consumption and require Real Driving Emissions (RDE) to be gauged on-road with Portable Emissions Measurement Systems (PEMS).

From laboratory to road – Real Driving Emissions

2016
In European emission type approval during the past years the exhaust emission limits have been reduced significantly. Although air quality was improved from 1990 on, a high percentage of the European population is exposed to air pollutant concentrations above European limit values, mainly on particles, nitrogen dioxide (NO2) and ozone (O3).

A new GPS-based method to estimate real driving emissions

2016 IEEE 19th International Conference on Intelligent Transportation Systems (ITSC), 2016
So far, real driving emissions knowledge involves installing Portable Emissions Measurement Systems (PEMS). As a consequence, large scale campaigns of measurement are not feasible. This paper describes an innovative coupling of Information and Communication Technology (ICT) and physical modeling to turn the driver's smartphone into a virtual sensor of ...
