HLDI Shows Impact on Claims from Auto-Emergency Braking, Changes to Powertrains

Matt Moore of the insurer-funded Highway Loss Data Institute (HLDI) offered some insights into the impact auto-emergency braking (AEB) could have on the frequency and severity of front-end crashes in the coming years, during his presentation at the recent Women’s Industry Network (WIN) virtual conference.

HLDI’s rating system for AEB systems involves two crash tests conducted at 25 mph and 12 mph. Those speeds may sound slow, he said, but “the more speed you can drop out of a crash, you drop out an exponential amount of energy.”


A 25 mph crash of a Mercedes C-Class resulted in more than $28,000 in damage, for example, Moore said, but when the speed was reduced to 12 mph, “the cost is reduced by more than half,” to $5,715.


“Of course, if  you can go from 12 mph down to zero, you can totally avoid that hit altogether,” he said.


AEB is expected to reduce front-end crashes that result in injury by more than 50%, Moore said. Of course, the potential benefits of AEB go away if consumers turn the system off.


But Moore said HLDI stationed researchers at some dealerships to check vehicles being dropped off for service. They found the lane departure systems on those vehicles were only left on 50% of the time, and Moore said he suspects even more drivers would turn that system off if doing so was easier. But the AEB remained active on almost 92% of the vehicles equipped with that system.


“Folks like it. They leave it on,” Moore said.


While automakers have voluntarily agreed to equip all new vehicles with AEB by September of 2022---and many automakers are ahead of schedule toward that goal---it still will take a long time for...
