However, AEB is already standard in 90% of new <a href=" target="_blank" rel="noreferrer noopener">cars</a> sold today. The regulations get very specific in their definition of AEB. Let’s break it down.</p>
<p id="par-2_56">Today, AEB is a feature that many drivers find in their newer cars. In a recent testing, though, the <a href=" target="_blank" rel="noreferrer noopener">IIHS</a> found that consumers might not understand how the system actually functions on their specific car. This is because automakers build and install their own versions of AEB systems. As such, AEB behaves differently in different models.</p>
<p id="par-3_24">What’s more, many automakers have previously committed to a voluntary agreement to install automatic emergency braking. However, the agreement is missing speed-related system triggers.</p>

<p id="par-4_27">Now, the <a href=" target="_blank" rel="noreferrer noopener">NHTSA</a> will enact standards across the board. In its <a href=" target="_blank" rel="noreferrer noopener">press release</a>, the NHTSA says that starting September 2029, new car AEB must be able to:</p>
<ul>
<li>Stop and avoid contact with a vehicle in front of them up to 62 mph</li>
<li>Detect pedestrians in both daylight and darkness</li>
<li>Apply the brakes automatically up to 90 mph when a collision with a lead vehicle is imminent</li>
<li>Apply the brakes automatically up to 45 mph when a pedestrian is detected</li>
</ul>
<p id="par-5_44">NPR reported that in testing 17 cars, only the 2023 Toyota Corolla with cameras and radar installed met these new standards. Overall, the NHTSA hopes that the path to fulfillment will be easy for OEMs since most already offer some version of automatic braking.</p>
<p id="par-6_20">The NHTSA says that the new rules will save hundreds of lives and prevent more than 20,000 injuries each year.</p>
