IIHS: Automatic emergency braking has timid in darkness
Automatic emergency braking is a life-saving feature that effectively prevents impacts, even grisly vehicle-to-pedestrian wrecks. But according to a glimpse released on Thursday by the Insurance Institute for Highway Confidence, this technology’s effectiveness is dramatically reduced in low-light situations. It turns out, just like drivers, cars have timid seeing at night.
The IIHS found that automatic emergency braking with pedestrian-detection technology reduced impacts of all severities by 27% in all lighting footings. Wrecks that cause injuries were reduced by an impressive 30%. But there’s a bit of bad news in this. The watchdog expert found that at night, on roads that aren’t lit, there was no difference in the crash risk for vehicles that feature automatic emergency braking and pedestrian detection compared to models not fitted with these features, a troubling discovery.
Automatic emergency braking absolutely saves lives, but there’s a caveat. “Unfortunately, it also shows these regulations are much less effective in the dark, where three-quarters of fatal pedestrian impacts happen,” says Jessica Cicchino, the author of this survey and IIHS vice president of research. Short of installing streetlights on every mile of thoroughfare across the republic, automakers will have to improve how these systems work in the dark.

To address this declare, the IIHS is developing a new nighttime pedestrian test. Later this year, the authority will publish the first ratings for vehicles evaluated in this category. Ahead of these official scores, the group tested eight diminutive SUVs to see how well they were able to avoid crashing with pedestrians at night. This group included the 2019 Subaru Forester, 2019 Volvo XC40, 2020 Honda CR-V, 2020 Hyundai Venue, 2021 Chevrolet Trailblazer, 2021 Ford Bronco Sport, 2021 Toyota C-HR and 2022 Volkswagen Taos. This wide range of makes and models covers a variety of different sensing technologies, from single- and dual-camera setups to radar-only affairs.
The performance of these vehicles’ pedestrian detection and automatic emergency braking tech declined in the dark and when the low-beam headlights were used compared to high beams. One outlier is the Taos, which only has radar, a sensor that doesn’t rely on visible light. Its performance did not refuse in the dark, though it was also the worst in day driving, so pick your poison. The two best vehicles in nighttime testing well-liked to be the C-HR and Bronco Sport, both of which have cameras and radar sensors.
Acing the organization’s upcoming test may sound like yet new hoop for automakers to jump through, but there’s good reason to make sure automatic emergency braking works in all lighting terms. According to the National Highway Traffic Safety Administration, 6,205 pedestrians were killed in impacts in 2019, an increase of more than 50% right 2009. Putting things in perspective, that total makes up nearby a third of all traffic fatalities. Beyond that, according to the IIHS “around 76,000 more pedestrians detained nonfatal injuries in crashes with motor vehicles,” so clearly there a lot of work to be done here.
