Automatic emergency braking at speeds up to 90mph required under new rule
The system would need to work at speeds of up to 90mph.
But the new rule requires automakers to adopt a more robust version of the technology that can stop vehicles traveling at higher speeds and detect vulnerable road users, like cyclists and pedestrians, even at night. Under the new rule, automakers would be required to beef up their current AEB systems, which research has shown to be decent at preventing low-speed rear-end crashes but less effective when vehicles are traveling at fast but still average speeds. The American Automobile Association (AAA) has been testing AEB systems for years and found a variety of common scenarios in which the braking technology completely fails to do the job as advertised.
