This SAE Recommended Practice (RP) establishes uniform powered vehicle-level test procedure for forward collision warning (FCW) and automatic emergency braking (AEB) used in trucks and buses greater than 10000 pounds (4535 kg) GVWR equipped with pneumatic brake systems for detecting, warning, and avoiding potential collisions. This RP does not apply to electric powered vehicles, trailers, dollies, etc., and does not intend to exclude any particular system or sensor technology. These FCW/AEB systems utilize various methodologies to identify, track, and communicate data/information to the operator and vehicle systems to warn, intervene, and/or mitigate in the momentary longitudinal control of the vehicle.

This document provides an assessment of current engineering test and simulation standards and methods used to determine the fuel efficiency, freight efficiency and emissions of single-vehicle systems comprised primarily of on-road trucks and buses with GVWR of more than 10000 pounds (4535 kg). This document provides guidance on the applicability and use of each test and simulation standard, method and technology discussed for multi-vehicle systems.

This SAE Recommended Practice establishes a uniform, powered vehicle test procedure and minimum performance requirement for lane departure warning systems used in highway trucks and buses greater than 4546 kg (10000 pounds) GVW. Systems similar in function but different in scope and complexity, including Lane Keeping/Lane Assist and Merge Assist, are not included in this document. This document does not apply to trailers, dollies, etc. This document does not intend to exclude any particular system or sensor technology. The specification will test the functionality of the LDWS (e.g., ability to detect lane presence, and ability to detect an unintended lane departure), its ability to indicate LDWS engagement, its ability to indicate LDWS disengagement, and determine the point at which the LDWS notifies the Human Machine Interface (HMI) or vehicle control system that a lane departure event is detected.

Scope: This document provides a taxonomy and definitions for trucks and buses with GVWR of more than 10,000 pounds with driving automation systems that perform part or all of the dynamic driving task on a sustained basis and that range in level from no driving automation (level 0) to full driving automation (level 5).

This SAE Recommended Practice (RP) establishes uniform powered vehicle level test procedure for Forward Collision Avoidance and Mitigation (FCAM) systems (also identified as Automatic Emergency Braking (AEB) systems) used in highway commercial vehicles and coaches greater than 4535 Kg (10,000 lb.) GVWR. This RP does not apply to trailers, dollies, etc. and does not intend to exclude any particular system or sensor technology. These FCAM systems utilize various methodologies to identify, track and communicate data to the operator and vehicle systems to warn, intervene and/or mitigate in the longitudinal control of the vehicle.

This SAE recommended practice establishes a uniform, powered vehicle T.P. for lane departure warning systems used in highway trucks and buses greater than 4,546 kg (10,000 lb) GVW. Systems similar in function but different in scope and complexity, including Lane Keeping/Lane Assist and Merge Assist, are not included in this T.P. This T.P. does not apply to trailers, dollies, etc. This T.P. does not intend to exclude any particular system or sensor technology. The specification will test the functionality of the LDWS (e.g., ability to detect lane presence, and ability to detect an unintended lane departure), its ability to indicate LDWS engagement, its ability to indicate LDWS disengagement, and determine the point at which the LDWS notifies the Human Machine Interface (HMI) or vehicle control system that a lane departure event is detected. The HMI is not addressed herein, but is considered in SAE Standard J2808.
