#AutomaticEmergencyBraking

Automatic emergency braking (AEB) should be mandatory, not voluntary, say safety groups, some of which have sued in order to see it happen.

It’s something of an odd situation, as one of the people behind a lawsuit filed against the National Highway Transportation Safety Administration is an ex-NHTSA administrator.

Automatic emergency braking is finding its way into more and more cars (and automakers have a pact to make it standard equipment by 2022), but most drivers don’t know the technology’s limitations.

AEB systems slow or stop a vehicle in an emergency, preventing or mitigating a crash, but an American Automobile Association study shows that 71 percent of U.S. drivers familiar with the technology believe AEB will prevent all crashes.

The National Highway Traffic Safety Administration on Tuesday announced significant changes to its tests and rating system for every new car in the U.S. Beginning in 2018, new cars will be rated on a five-star system, in half-star increments (for the first time), and will encompass information from new tests — including front overlap crashes already in use by other safety organizations — and pedestrian impact information.

The proposed changes would place an emphasis on active safety features such as blind spot monitoring and crash avoidance systems. The announcement Tuesday followed a statement last month that the agency would recommend automatic emergency braking on new cars beginning in 2018.

“The changes provide more and better information to new-vehicle shoppers that will help accelerate the technology innovations that saves lives,” said U.S. Transportation Secretary Anthony Foxx.
