Automatic Emergency Braking Test Devices: Heavy Vehicle Automatic Emergency Braking

SAE International, a global mobility standards development organization, is requesting a 30-day extension of the comment deadline for the proposed rule on Heavy Vehicle Automatic Emergency Braking test devices. They explain that their committee needs more time to gather recommendations from member subject matter experts and stakeholders.

The Truck and Engine Manufacturers Association (EMA) is requesting a 30-day extension of the comment period for the proposed rule requiring electronic stability control (ESC) and automatic emergency braking (AEB) on heavy vehicles. They argue that the rulemaking is technically complex and that the current proposal does not fully align with the procedural requirements set forth in the Bipartisan Infrastructure Law.

The Commercial Vehicle Safety Alliance (CVSA), representing the Commercial Vehicle Brake Manufacturers Council (CVBMC), is requesting a 30-day extension to the comment period for the proposed heavy vehicle automatic emergency braking requirements. They argue that more time is needed to facilitate industry-wide discussions and gather comprehensive, data-based feedback from stakeholders.

The commenter, representing a trucking fleet owner, supports the mandate of Automatic Emergency Braking (AEB) systems on commercial vehicles but warns that current radar technology is prone to "ghost" activations and malfunctions in various environmental conditions. They recommend that the rule include a grace period for compliance, require OEM improvements to prevent unintended braking, and advocate for better driver education for non-commercial drivers.

A truck owner who operates a Freightliner Cascadia expresses concern over the unreliability of current Automated Emergency Braking (AEB) technology. They argue that the system is prone to false positives that create safety hazards and are not yet sophisticated enough for use on commercial vehicles.

A former truck driver argues that the Automatic Emergency Braking (AEB) system in certain heavy vehicles is unsafe because it causes the truck to lock up. The commenter supports disabling the device as the only way to ensure safe operation of the vehicle.

The commenter supports the inclusion of bicycle-specific safety standards in the proposed heavy vehicle automatic emergency braking regulations. They argue that NHTSA should adopt established international testing protocols, such as ECE Regulation No. 152 and various NCAPs, to ensure vehicles are safe for cyclists and pedestrians.

A professional truck driver argues that Automatic Emergency Braking (AEB) systems are unsafe because they frequently trigger false emergency braking events. The commenter shares personal experiences where these malfunctions caused dangerous trailer swings and nearly led to collisions with oncoming traffic.

The commenter supports the inclusion of bicyclist-specific automatic emergency braking (AEB) testing standards in the proposed federal action. They argue that NHTSA should adopt established international standards, such as ECE Regulation No. 152 and various NCAP protocols, to ensure vehicle safety for cyclists.
