The first applies a little more braking force if the driver doesn’t brake enough in an accident situation, while the second slows the car down when the front sensors compute a crash scenario.
Yup, summing things up again, that’s pretty much what any modern AEB system does.Compared to the NHTSA’s rather late change of heart, AEB is a mandatory feature to pick up the IIHS’ desirable Top Safety Pick+ rating, as well as scoring 5 stars in the Euro NCAP testing program.
These AEB systems, along with promising innovations such as vehicle-to-vehicle communications (V2V) and automated vehicle technologies hold promise to save even more lives and prevent fatal crashes.
According to data sourced by the NHTSA, one-third of all police-reported vehicle crashes in 2013 involved a rear-end collision with another car at the start of the crash. The safety agency found that many drivers involved in rear-end crashes either did not apply the brakes at all or did not apply the brakes fully prior to the crash.
Crash imminent braking and dynamic brake support systems can intervene by applying the vehicle's brakes or supplementing the driver's braking effort automatically in order to mitigate the severity of the crash or to avoid it altogether.
