美国政府正在向五星级安全评级系统增加自动制动，旨在帮助消费者确定在新车中寻找最重要的安全技术。
The National Highway Traffic Safety Administration said automatic braking will be added to the ratings beginning with 2018 model cars.
该机构于9月宣布，它已达成自愿协议与10家汽车制造商，将该技术作为新车的标准纳入，但没有提供时间表。
The systems use sensors to warn of an imminent collision and, if the driver does not apply the brakes, engage the brakes automatically.
Accident investigators estimate automatic braking could prevent or mitigate an estimated 80 percent of rear-end collisions that cause about 1,700 deaths and a half-million injuries annually.
