Analysis of the Euro 7 on-board emissions monitoring concept with real-driving data
分析了欧7标准中车载监测系统的概念，利用实际驾驶数据讨论其可行性、挑战及对排放合规的影响，对汽车工程师和政策制定者有参考价值。
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.
