Automatic Emergency Braking FAIL | Chevrolet, Ford, Honda & Toyota Tested

Touted as lifesaving, crash-preventing tech, Automatic Emergency Braking (AEB) is standard equipment in most new cars sold in the United States. Over the years, AEB has successfully stemmed rear-end crashes, which often result in injuries, property damage, and even fatalities. But AAA wanted to know if the latest generation of AEB can handle higher speeds and detect moving vehicles in its path at intersections. It struggled with the former and failed with the latter.

The Issue

AEB uses forward-facing cameras and other sensors to automatically tell the car to apply the brakes when a crash is imminent. It has reduced rear-end crashes at slower speeds, and the technology has been refined over the years with upgraded hardware and software. But two of the most common deadly crashes at intersections are T-bones and left turns in front of oncoming vehicles. From 2016 to 2020, these two types accounted for 39.2% of total fatalities in crashes involving two passenger vehicles during which the striking vehicle did not lose traction or leave the roadway before the collision.

What AAA Tested
AEB rear-end crash performance when encountering a stationary vehicle at speeds of 30 and 40 mph (currently mandated testing speeds are 12 and 25 mph)
AEB performance when encountering moving vehicles in collision scenarios involving an intersection – T-bone and unprotected left turn (test vehicle turning left in front of an oncoming car)

The Result
-At 30 mph, AEB prevented a rear-end collision for 17 of 20 test runs, or 85%. For the test runs that resulted in a crash, the impact speed was reduced by 86%.
-But at 40 mph, AEB only prevented a rear-end crash in 6 of 20 test runs, or 30%. For test runs that resulted in a crash, the impact speed was reduced by 62%.
-In both the T-bone and left-turn in front of oncoming vehicle tests, crashes occurred 100% of the time. AEB failed to alert the driver, slow the vehicle’s speed and avoid the crash.

AEB is common in vehicles, regardless of price. Starting on September 1, 2022, 20 automakers representing more than 99% of the US market pledged to make AEB standard equipment on all their new vehicles.

Models tested :
-2022 Chevrolet Equinox LT with “Chevy Safety Assist”
-2022 Ford Explorer XLT with “Pre-Collision Assist with Automatic Emergency Braking”
-2022 Honda CR-V Touring with “Honda Sensing”
-2022 Toyota RAV4 LE with “Toyota Sensing”

Why is it so satisfying to watch the fake car get "disassembled"?
Now I need a video game simulation like this.

[nothughmahn]

Most cars with AEB are not equipped to detect cross-traffic. Also, AEB is not a superpower and cannot avoid a collision with such short notice. Higher end vehicles such as Teslas come equipped with sensors mounted on the side of the front end to detect cars coming up perpendicular.

[ProCoach]

All the tests minus the rear end collision examples were unfair. Regardless, I get the feeling people think these systems provide more safety than they really do.

[woolfy]

I wonder who the poor soul / employee is, that has to re assembly the 'car' each time lol

[bluebirdfan]

Where did they get all these Chinese cars to hit??

[chriswatson]

Because they expect drivers to brake as well, the aeb just provides the brake force to prevent to collision.

[scottd]

It's a learning curve. Better than not having it. It would have saved me hitting another car one year ago today.

[wubster]

These systems can only detect the rear of vehicles and pedestrians so it's obvious that they will fail the other tests.

[Nicholasboii]

I would think the tape would be messing w/ the sensors

[rickt]

have anything to do with the blow up car not being metal?

[KanniPro]

Official meaning of 'Bro didn't even hesitate.'

[thechronicphilosopher]

Hyundai, KIA, BMW, Volvo, Mercedes-Benz, Lamborghini, Ferrari, Tesla, Lucid, Vinfast & Polestar have great AEB system in my opinion

[wumcesw]

I wonder what year and make those cars are. For example, the EU version of the RAV4 received a facelift in 2023, incorporating the latest Pre-Collision System (PCS) capable of detecting pedestrians and most of the collisions( also on intersections). However, most of the collision tests were conducted on the previous model. I believe this makes the test results somewhat unfair. Additionally, every car manufacturer advises against relying solely on these systems and emphasizes the importance of staying cautious while driving.

[jaysmokin]

How’s it supposed to work if you covered up the sensors this is a bad test

[Kerr]

This is where Kia comes in clutch. If you wanted good aeb you should’ve got a Hyundai or a Kia.

[mandarp]

Tesla with AI needs to design braking system which can work in all conditions, day & night.

[Chromebook]

LIKE HALF THE CAR WAS TAPED OFF NO WONDER IT DIDN'T WORK💀💀💀💀

[daleb]

right, this is Merica dammit! Outta mAh way! Lol

[darkketchup]

its not a fail, i think no sensor can predict a sudden crossing car., but can predict if its in front, and can react to that distance, but crossing no...
if there is an un-controlled intersection, we should all adjust to slowing down, anticipating crossing cars..

These soccer moms don't take shit off anybody!
