Two new U.S. research present that computerized emergency braking can minimize the variety of rear-end car crashes in half, and cut back pickup truck crashes by greater than 40%.
The research launched Tuesday, one by a government-auto business partnership and the opposite by the insurance coverage business, every used crash information to make the calculations. Automated emergency braking can cease autos if a crash is imminent, or sluggish them to scale back the severity.
Some automakers are shifting towards a voluntary dedication by 20 corporations to make the braking expertise commonplace gear on 95% of their light-duty fashions through the present mannequin 12 months that ends subsequent August.
A examine by The Partnership for Analytics Analysis in Visitors Security in contrast information on auto gear with 12 million police-reported crashes from 13 states that was collected by the Nationwide Freeway Visitors Security Administration, the partnership mentioned in a press release Tuesday.

The group discovered front-to-rear crashes have been minimize 49% when the hanging car had ahead collision alert plus computerized braking, when put next with autos that didn’t have both system. Rear crashes with accidents have been minimize by 53%, the examine discovered.
Autos with ahead collision warning methods solely lowered rear-end crashes by 16%, and minimize rear crashes with accidents by 19%.
Automated emergency braking works nicely in all circumstances, even when roadway, climate or lighting circumstances weren’t supreme, the examine confirmed.
The group additionally checked out lane departure warning methods, and lane-keeping methods, which preserve autos of their lanes. They lowered crashes from autos leaving the roadway by 8% and road-departure crashes that trigger accidents by 7%.
“These rising applied sciences can considerably cut back the variety of crashes and enhance security outcomes,” mentioned Tim Czapp, senior supervisor for security at European automaker Stellantis, the business co-chair of the partnership’s board.
Within the different examine, the Insurance coverage Institute for Freeway Security discovered that computerized emergency braking reduces rear crash charges for pickups by 43% and rear-end damage crashes by 42%. But pickups are much less more likely to have computerized braking than vehicles or SUVs regardless of posing extra hazard to different highway customers, the IIHS discovered.
“Pickups account for 1 out of 5 passenger autos on U.S. roads, and their giant dimension could make them harmful to individuals in smaller autos or on foot,” the institute’s Vice President of Analysis Jessica Cicchino mentioned in a press release.
Mitsubishi, Ford, Mercedes-Benz, Stellantis (previously Fiat Chrysler), Volkswagen and Honda have filed paperwork with the federal government this 12 months saying they’ve made emergency braking commonplace on no less than 90% of their fashions.
Basic Motors reported that solely 73% of its fashions had the expertise on the finish of the 2022 mannequin 12 months, however a spokesman mentioned GM would hit 98% by the tip of the present mannequin 12 months so long as there aren’t provide chain points.
As well as, BMW, Hyundai, Mazda, Subaru, Tesla, Toyota, and Volvo handed 90% final 12 months, in line with the IIHS.
