The Goal of Automatic Brakes: Reducing the Number of Rear-End Crashes

Updated July 31, 2020 | By Wilson Kehoe Winingham staff

Safer cars are coming soon, and drivers will have a new kind of braking system to thank for it: the automatic emergency braking (AEB) system.

The National Highway Traffic Safety Administration (NHTSA) announced that it has received a commitment from the top 20 automakers in the United States to install AEB systems as a standard feature on their cars. The enhancement is scheduled to take place no later than September 1, 2022.

Automatic Emergency Braking Systems

AEB systems come in two forms. They are designed to either provide more braking when a driver isn’t slowing down quickly enough or to brake entirely on their own when a driver isn’t slowing at all.

An AEB system uses information from sensors in the vehicle combined with its on-board computers to determine when a collision risk exists and to take appropriate action. These systems are a natural evolution of other vehicle technologies including anti-lock brakes and collision avoidance systems.

Preventing Rear-End Collisions

The goal of making AEB systems standard is to reduce the number of rear-end car accidents.

The NHTSA estimates that more than half a million Americans were injured and around 2,400 killed in 2018 because of rear-end crashes, accounting for more than 32% of all collisions.

The agency believes that AEB systems could reduce the severity of rear-end crashes in some situations or even avoid them entirely.

Cars, then Trucks

The AEB rollout will happen first on cars and light trucks of up to 8,500 pounds. That covers essentially all passenger vehicles on the road today, as well as most vans and many pickups. By 2025, however, manufacturers have committed to also include AEB on the majority of heavier vehicles (up to 10,000 pounds), not including semis and other large commercial vehicles, which both the government and the trucking industry are addressing.

This commitment from automakers is a new approach. The NHTSA and the Department of Transportation chose to work with manufacturers and the Insurance Institute for Highway Safety (IIHS) rather than impose mandatory regulation in the hope that it would streamline the process and bring safety benefits to consumers more quickly.

By its own estimate, if the NHTSA had made AEB mandatory through regulation, it would have taken until at least 2025 to reach the target now anticipated for 2022. During those three years, IIHS has estimated that an additional 28,000 crashes and 12,000 injuries would have happened. “It’s a win for safety and a win for consumers,” said Anthony Foxx, United States Transportation Secretary.

Crash Fatalities Near All-Time Low

Cars are much safer than they used to be, in large part due to improved safety technology. The absolute number of traffic injuries and deaths has hovered around an all-time low since 2009 and has dropped close to 40 percent since the peak in the late 1970s.

New features such as AEB might improve safety even more over the next decade, but these numbers might not go much lower until the ultimate safety risk—the driver—is removed from the equation by self-driving vehicles.
