#科技頭條# 【美國政府:必須買有智能剎車的汽車?】

Open Road
智能汽車還很遠,智能剎車要來了。美國國家公路交通安全委員會稱2018年前將強制汽車安裝智能剎車。其推薦的智能剎車帶有傳感器,能在將要撞車但司機沒有踩剎車時自動剎車。該委員會稱絕大多數車禍屬于追尾事故,智能剎車有利于減少追尾事件發生。

Autonomous cars?may have been all the rage at this year's?Consumer Electronics Show, but most of the tech showcased is still pretty far off. What isn't, however, are smarter stopping systems. In fact, the?National Highway Traffic Safety Administration?is adding crash imminent braking and dynamic braking support to its list of recommended advanced safety features for new cars. The former uses sensors to activate the brakes if a crash is imminent and the driver already hasn't. Dynamic braking support, on the other hand, increases stopping power if you haven't put enough pressure on the brake pedal. Like lane-departure and front collision warning systems, these features are available on some models already -- this move gives them high-profile attention, though.

And for good reason: As the NHSTA tells it, a third of 2013's police-reported car accidents were the rear-end crashes and a "large number" of the drivers either didn't?apply the brakes?at all (what?!) or fully before impact. Like?The Los Angeles Times?and?Ars Technicanote, this is far from becoming a mandate but that isn't out of the realm of possibilities. For example, backup cameras'll be required equipment on every vehicle come 2018.
