This Recommended Practice provides a taxonomy for motor vehicle driving automation systems that perform part or all of the dynamic driving task (DDT) on a sustained basis and that range in level from no driving automation (level 0) to full driving automation (level 5). It provides detailed definitions for these six levels of driving automation in the context of motor vehicles (hereafter also referred to as “vehicle” or “vehicles”) and their operation on roadways. These level definitions, along with additional supporting terms and definitions provided herein, can be used to describe the full range of driving automation features equipped on motor vehicles in a functionally consistent and coherent manner.
SAE J3131 defines an automated driving reference architecture that contains functional modules supporting future application interfaces for Levels 3 through 5 (J3016). The architecture will model scenario-driven functional and nonfunctional requirements, automated driving applications, functional decomposition of an automated driving system, and relevant functional domains (i.e., functional groupings). Domains include, but are not limited to, 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 a safe state). The architecture will address Tier 1 and Tier 2 functional groupings. The document will include one example instantiation being divides the functionality into two functionality groupings, and will detail the functional and information interface between the groups.
The purpose of this document is to provide information and guidelines for use by automotive designers, test engineers and policymakers with…
Guidelines for Safe On-Road Testing of SAE Level 3, 4, and 5 Prototype Automated Driving Systems (ADS)
This document provides guidelines for the safe conduct of on-road tests of vehicles equipped with prototype conditional, high, and full (levels 3-5) automated driving systems (ADSs), as defined by SAE J3016. It does not include guidance for testing production ADSs intended for sale to the general public. The scope is further limited to testing of automated prototype vehicles on public roads. These guidelines do not address: Testing of driver assist (Level 1) or partial (Level 2) automation systems, which rely on a human driver to monitor the environment. (See SAE J3016 for Definitions of Levels of Automated Systems.) Closed-course testing. Component-level testing. The precise regime of road testing for a particular prototype will depend on the intended level of automation and the targeted capabilities of the prototype (see SAE J3016 for more information).
This Information Report provides a taxonomy for motor vehicle automation ranging in level from no automation to full automation. However, it provides detailed definitions only for the highest three levels of automation provided in the taxonomy (namely, conditional, high and full automation) in the context of motor vehicles (hereafter also referred to as “vehicle” or “vehicles”) and their operation on public roadways. These latter levels of advanced automation refer to cases in which the dynamic driving task is performed entirely by an automated driving system during a given driving mode or trip. Popular, media, and legislative references to “autonomous” or “self-driving” vehicles encompass some or all of these levels of automation. These definitions can be used to describe the automation of (1) on-road vehicles, (2) particular systems within those vehicles, and (3) the operation of those vehicles.
