IEEE 1616.1-2023

This standard defines requirements and metrics for data storage in a data storage system for automated driving (DSSAD), as well as related functions and common technical requirements. A DSSAD is a device or function that records and stores a data set (“timestamped flags”) during the automated driving sequences of any vehicle equipped with Level 3, Level 4, or Level 5 automated driving systems (ADS). The standard conforms to a compendium of data elements used in vehicles of categories M1 (used for the carriage of passengers) and N1 [used for the carriage of goods (trucks)] regarding their event data recorder (EDR) and DSSAD for partial and fully automated vehicles, including relevant data elements to ADS Level 3, Level 4, and Level 5 (see Figure 1 for all ADS levels). This standard explains the means by whereby an EDR and a DSSAD interact. This standard is made available without prejudice to national, local, and regional laws and regulations related to data privacy, data protection, and personal data processing. Users are responsible for compliance with all such laws and regulations. This standard defines an onboard diagnostic connector (OBD-II) port lockout and near field communication (NFC) protocol for protection against data manipulation of EDR and DSSAD data via the vehicle diagnostic link connector (DLC). This standard does not include specifications for data retrieval tools and methods as that is subject to national and regional requirements. New IEEE Standard - Active. The goals and metrics of a data storage system for automated driving (DSSAD) are defined in this standard. Functions and common technical requirements for data storage are identified. Data elements relevant to automated driving system (ADS) Level 3, Level 4 and Level 5 are defined. The usage of data among diverse end users is also defined. A compendium of data elements used in vehicles of categories M1 and N1 regarding their EDR and DSSAD for partial and fully automated vehicles is provided in this standard. An on-board diagnostic (OBD) port lockout/near field communication (NFC) protocol for protection against data manipulation via the vehicle diagnostic port is provided. This standard is made available without prejudice to national and regional laws related to data privacy, protection, and personal data processing. Users are responsible for compliance with all such laws and regulations. This standard may be frequently updated to include relevant data definitions and data elements toward the development of automated vehicles. The overall goal is to create a data collection standard for automated driving that includes functional requirements for automated vehicle gateways and security guidelines for cloud-based automotive data recorder requirements.
