The European Union issued COMMISSION REGULATION (EU) 2018/1832, which requires vehicles to be equipped with devices, i.e. On-Board Fuel and/or Energy Consumption Monitoring （OBFCM）devices, which can measure fuel consumption in real time, requires the accuracy of the collected data and requires that the fuel consumption data stream should meet the current vehicle-machine communication standards. In this paper, the feasibility of vehicle terminal coverage of OBFCM is studied by comparing and analyzing the OBFCM device and the policy, function and technology of vehicle fuel consumption monitoring in real time. The results show that the vehicle terminal coverage OBFCM device can be applied in all aspects above, and has great development prospects. China should carry out the collection of driving data for fuel consum-ption as soon as possible and establish relevant industry standards.
