One Goal, Multiple Pathways: a Review of Approaches for Transferring On-board Fuel Consumption Meter Data to the European Commission
The European Union's carbon dioxide (CO₂) emissions standards for light-duty vehicles (LDVs), adopted in April 2019, require the European Commission (EC) to monitor the fuel and electricity consumption of LDVs to analyze the gap between actual and approved CO₂ emissions. The data for the analysis will be recorded by On-board Fuel Consumption Meters (OBFCM), which will be introduced in new LDVs over two years starting January 1, 2020. A procedure remains to be developed for the transfer of OBFCM data from vehicles to the EC. This paper analyzes the data transfer requirements, data transfer methods, and potential uses of the OBFCM data. The authors considered four methods of data transfer. In the first three methods, the data are read from the vehicle and a third party transfers them to the EC. The fourth option is over-the-air (OTA) data transfer from the vehicle directly to the EC. The authors recommend this method. Automatic OTA transfer allows for regular fleet-wide collection of OBFCM data, while vehicle owners’ privacy is ensured by cryptography. The main reason for collecting OBFCM data is to monitor the gap between approved and actual CO₂ emissions, and the derived information will be used to develop measures ensuring that the gap does not increase. The OBFCM data is valuable too for other purposes, such as informing consumers about real fuel and energy consumption to help them identify and purchase eco-friendly vehicles. The OBFCM data should also be used to determine more realistic approved CO₂ emission levels for hybrid vehicles, by analyzing the real-world share of electric driving. The data could be used in other important research, such as analyzing the effect of vehicle age or driving conditions on CO₂ emissions, or the effectiveness of technological innovations on reducing the gap between approved and actual CO₂ emissions. The authors recommend that the anonymized data be made publicly accessible to enable research and to satisfy public interest in vehicle emissions and climate change.
