The Design of Operational Design Condition for Automated Driving System

<div>A new revolution has taken place in the automobile industry in recent years, intelligent and connected vehicle (ICV) [<span>1</span>] has achieved a higher market share in recent years and relevant technologies have been quickly developed and widely accepted, so the auto industry needs to make regulations for automated driving system (ADS) on ICVs, mainly to assure the safety of ICV. To meet the requirements above, the definition of operational design domain (ODD) [<span>2</span>, <span>3</span>] was put forward by the Society of Automotive Engineers (SAE) and International Organization for Standardization (ISO) a few years ago. ODD defines necessary external environment conditions for the ADS to operate, but the internal status of the vehicle is also a key part of judging whether ADS can operate safely. Based on that, we propose a novel definition named operational design condition (ODC), which can supersede ODD to play a bigger role in improving regulations and standards, and promoting vehicle safety and technological development. We summarize the research about ODD, analyze the relationship between ODC and ODD, and list the advantages of the proposed definition of ODC. ODC is designed based on the principle of layered description, concerns for safety, perceivable, and minimal collection, which will promote technologies and cooperation based on a deeper and common understanding.</div>
