The On Road Automated Vehicle (ORAV) committee reports to the Driver Assistance Systems steering committee of the Motor Vehicle Counsel. The committee is responsible for developing and maintaining SAE standards, recommended practices, and information reports related to motor vehicle driving automation systems that perform the dynamic driving task across the full range of levels of automation. “On-road” refers to publicly accessible roadways that provide driving environments for the users of motor vehicles of all classes and all levels of automation. However, the ORAV will focus primarily on automated driving systems at the higher levels of conditional, high, and full automation as defined by J3016. This includes cooperative automation at these levels. While automated subsystems from other committees will be integrated as part of the automated driving system ORAV does not focus on specific short-range communication systems and active safety systems such as electronic stability control and automated emergency braking and other types of specific driver assistance systems such as lane keeping and cooperative adaptive cruise control. The committee engages industry, technology, and systems experts from automotive manufacturers, automotive equipment suppliers, government safety and regulatory organizations, university robotics and research and development organizations, Department of Defense robotics organizations, commercial robotics research and development organizations, and industry consultants. Recommended practices and standards are likely to address safe testing, public data, performance requirements, evaluation and simulation, and security. The current activities also focus on the systems and functional subsystems levels of the model-based systems engineering process in the areas of concepts of operations and approval including definitions, taxonomies of systems and levels of automation, and verification and validation. The following are some of the past and current task force activities supporting automated driving systems:

  • Planning for industry standards: This ad hoc task force (1) coordinates with other SAE committees and with external organizations doing complementary work, including ISO, UNECE, NHTSA, IEEE, ULC, and AAMVA (among others), (2) identifies areas where technical guidance is still needed, and (3) recommends future activities to the full committee.
  • Taxonomy and definitions (J3016): This Information Report provides a taxonomy for motor vehicle driving automation systems that perform part of, or the entire dynamic driving task on a sustained basis and that range in level from no automation (level 0) to full automation (level 5). It provides detailed definitions for these six levels of driving automation in the context of motor vehicles and their operation on roadways. These level definitions, along with additional supporting definitions can be used to describe the range of driving automation systems equipped on motor vehicles in a functionally consistent and coherent manner.
  • Dynamic Test Procedures for Verification & Validation of Automated Driving Systems (ADS) (V&V, J3092, J3018): This document provides dynamic test procedure information and guidelines for verification and validation (V&V) of automated driving systems (ADSs). The levels of automation addressed in this document include conditional (level 3), high (level 4), and full (level 5) as defined by SAE J3016. The information and guidelines contained within apply to the verification and validation (V&V) of all types of motor vehicles including light-duty, passenger, freight or transit vehicles by specifying dynamic test procedures, such as those performed on a test track, for verifying and validating ADS functions. This document does not address component-level V&V or broader top-down systems-level V&V practices. Safe On-Road Testing (J3018) was folded into V&V and provides general safety-relevant guidelines for performing tests of prototype automated driving systems (ADSs) equipped on test vehicles operated in mixed-traffic environments on public roads. The levels of automation addressed in this document include conditional (level 3), high (level 4), and full (level 5) as defined by SAE J3016; when activated, these ADSs do not rely on a human driver for monitoring and responding to the vehicle or traffic environment.
  • Reference architecture and interfaces (RAI, J3131): SAE J3131 defines the automated driving reference architecture that contains functional modules supporting future application interfaces for Levels 3 through 5 (J3016). The architecture will address scenario-driven functional and nonfunctional requirements, automated driving applications, functional decomposition of the automated driving system, and relevant functional domains (i.e., functional groupings). Domains include automated driving (i.e., automation replacing the human driver), by-wire and active safety, and those related to automated recovery from faults and system failures (e.g., system bringing the vehicle to minimal risk conditions).

Possible future activities include recommended practices and standards for minimal risk condition, 3D prior maps for localization, cybersecurity, interfaces, features supporting software component level interoperability, and automated vehicle features for mobility impaired. Recommended practices standards will promote the interoperability of automated driving systems/subsystems from different suppliers, minimizing the integration effort, and helping to ensure the extensibility and flexibility of these systems for future applications. It should also help minimize redesign and recertification of safety critical aspects of these systems while allowing manufacturers to focus on differentiating their products on customer features.
