Abstract
- The Euro 7 standard is expected to intensify its focus on real-driving emissions compliance thanks to the on-board monitoring (OBM) system. OBM is designed to bridge the gap between emission limits and real-world vehicle emissions by continuously monitoring their levels using on-board sensors and models. Essentially, this system aims to verify vehicles compliance, prompt timely repairs otherwise, and provide authorities with emissions data for fleet inspection. Leveraging a large real-driving emissions database from an in-service Euro 6d-Temp vehicle, this paper reviews the current OBM proposal and discusses its possible outcomes and challenges using available sensor technology. • The Euro 7 on-board monitoring concept is reviewed and discussed. • On-board monitoring emissions assessment is analyzed with real-driving data. • Challenging aspects regarding the correct emissions estimation are highlighted. • More than 60% of the NOx trip information can be lost due to sensor light-off delay.
