20 automakers commit to make automatic emergency braking standard on new vehicles no later than 2022; faster than regulatory process

The US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) announced the commitment by 20 automakers representing more than 99% of the US. auto market to make automatic emergency braking (AEB) a standard feature on virtually all new cars in the US no later than NHTSA’s 2022 reporting year, which begins 1 Sept 2022.

Automakers making the commitment are Audi; BMW; FCA US LLC; Ford; General Motors; Honda; Hyundai; Jaguar Land Rover; Kia; Maserati; Mazda; Mercedes-Benz; Mitsubishi Motors; Nissan; Porsche; Subaru; Tesla Motors; Toyota; Volkswagen; and Volvo Car USA. The unprecedented commitment means that this important safety technology will be available to more consumers more quickly than would be possible through the regulatory process.

Automatic emergency braking helps prevent crashes or reduce their severity by applying a vehicle’s brakes automatically. The systems use on-board sensors such as radar, cameras or lasers to detect an imminent crash, warn the driver, and apply the brakes or increase braking effort if the driver does not take sufficient action.

NHTSA hosting public meetings on automated vehicles
NHTSA will hold a pair of public meetings this spring to gather input as it develops guidelines for the safe deployment of automated safety technology. The meetings, to be held in Washington, D.C., and California, will gather information on a series of issues related to safe operation of automated vehicles as part of NHTSA’s efforts to provide manufacturers with operational guidance.
The agency also recently released an initial assessment of current Federal Motor Vehicle Safety Standards that identifies key challenges in full deployment of automated vehicles. The report, prepared by USDOT’s Volpe National Transportation Systems Center, found that there are few existing federal regulatory hurdles to deployment of automated vehicles with traditional designs and equipment to accommodate a human driver.
The report also found that there may be greater obstacles to vehicle designs without controls for human drivers, such as a steering wheel or brake pedals. The Volpe Center produced the report at the request of NHTSA and DOT’s Intelligent Transportation Systems Joint Program Office.

NHTSA estimates that the agreement will make AEB standard on new cars three years faster than could be achieved through the formal regulatory process. During those three years, according to IIHS estimates, the commitment will prevent 28,000 crashes and 12,000 injuries.

The commitment will make AEB standard on virtually all light-duty cars and trucks with a gross vehicle weight of 8,500 lbs (3,856 kg) or less beginning no later than 1 Sept. 2022. AEB will be standard on virtually all trucks with a gross vehicle weight between 8,501 lbs. and 10,000 lbs (4,536 kg) beginning no later than 1 Sept. 2025.

Participating manufacturers will ensure vehicles have both a forward collision warning system that meets a subset of the National Highway Traffic Safety Administration's current 5-Star Safety Ratings program requirements on the timing of driver alerts and an automatic braking system that earns at least an advanced rating in the current Insurance Institute for Highway Safety front crash prevention track tests. The baseline performance measures are a speed reduction of at least 10 mph (16 km/h) in either the IIHS 12 or 25 mph (19 or 40 km/h) tests, or a speed reduction of 5 mph (8 km/h) in both of the tests.

As NHTSA continues its regulatory work in this area, NHTSA will track the progress industry is making towards its commitment.

The commitment takes into account the evolution of AEB technology. It requires a level of functionality that is in line with research and crash data demonstrating that such systems are substantially reducing crashes, but does not stand in the way of improved capabilities that are just beginning to emerge. The performance measures are based on real world data showing that vehicles with this level of capability are avoiding crashes.

To encourage further development of AEB technology, NHTSA will accelerate its research on more advanced AEB applications, including systems that reduce the risk of collisions with pedestrians. In December, NHTSA announced plans to rate AEB systems and other advanced technologies under its 5-Star Safety Ratings beginning in model year 2018.

Based on mounting evidence that AEB effectively reduced crashes and injuries in the US and around the world, NHTSA and IIHS issued a challenge to industry in September 2015 to encourage automakers to voluntarily make AEB a standard feature. A series of meetings followed to establish details of the commitment.

NHTSA and IIHS also announced that Consumer Reports will assist in monitoring automaker progress toward meeting the AEB commitment.

This is fantastic news. Nice example of how public/private can work together to launch new services that can save thousands of lives - the rest of the federal government should learn from this!


Wow, it's not very often we can say this, but everyone came together and did the right thing here. What fantastic news for all of us.


Brakes on long haul and short run trucks have been unreliable for years with most failures caused by brake fade. Time to address the problem, set standards, monitor the systems with warnings for the driver and apply emergency engagements as necessary. Too bad they don't have variable regen electric braking.

We are still not doing enough fast enough with regard to safety measures in the global auto-industry. That industry is constantly lobbying for not having to make their cars safer because it hurt them in profits and sales. The result is 1.2 million traffic death per year and millions more crippled for life and hundreds of billions worth of dollars lost in property and forgone work from injured and dead people. If we did everything possible we could probably safe a million lives per year and many hundreds of billions of USD. Making forward looking anti-collision low speed systems mandatory on all cars by 2022 is not enough. It should be 360 degrees at all speeds. We also need tire pressure sensors and brake system sensors to warn and ultimately disable the vehicle when the tire pressure or brakes are not functioning 100%. We need it now because it can be done today. Give the auto-makers 36 months. That is enough to ramp up production of the necessary parts especially when your job depends on it. Automakers that are not in compliance should be barred from selling the non-compliant cars.


Just wait until they get sued for this causing a few accidents. They tried this on airliners, and over ruling the pilot caused accidents.

Technology like this (and further measures suggested above!) can not be legislated into existence before the technology itself is ready for prime time. False triggering is still something of an issue and it can certainly cause crashes, and the technology has to be refined far enough to minimize the chance of that (and this risk can probably never be completely eliminated).

In its current state, self-driving is likely better than a poor driver most of the time, possibly better than an average one some of the time, but not better than a good driver. It does not deal with adverse weather very well, and typically the only response that these systems know how to do is to slam on the brakes even when something else would be more appropriate. Would it know to not slam on the brakes if there is a vehicle behind that wouldn't be able to make the stop?

The agreement to do this without being legislated to do so means that appropriate engineering compromises can be made. The systems will get better as time passes.
