Although we have had no about accidents due to false-positive auto-braking, vehicles we test do sometimes apply braking when we would have chosen not to brake. There are two independent scenarios in which this occurs. The first is when you are following a vehicle and it is signaling a right turn ahead into a side street. By habit, many drivers will swing wide in the lane and plan to fair miss the rear corner of the turning fomite. This is something a driver can judge by exercise. The driver knows the turning rush, knows the close outdistance, and can adapt if need be at the stopping point moment. AEB thinks you ’ re nuts and will brake. It does not fully stop your vehicle. It equitable slows you so that you will pass safely. Apply gas or turn and it will stop brake .

A second gear scenario is like. It occurs on the highway when one is using adaptive cruise command and a vehicle ahead slows. You check your left rear, use a turn signal, and plan to pass the fomite ahead by a safe distance, but the AEB and adaptive cruise control systems see the vehicle ahead slowing and the systems begin to slow you a well to maintain the pre-set vehicle spacing distance. The brake can feel abrupt, but again, it is not going to stop the fomite in full, just brake to keep the spacing. If you use the accelerator or turn it will disengage .
With indeed many vehicles tested by our staff of five weekly testers, and with not a one case of a vehicle brake in a situation in which it would have caused an accident, it is hard for us to provide our own real-world proof that auto-braking can be a gamble. however, we can all report that it can be a fuss .

The warnings that these systems provide are another history raw. The systems provide so many false positives it is hard to know where to begin listing them. Let ’ s start with a holocene example. We tested a Nissan Maxima that for a fully workweek of testing never squawked at us once. Our future test vehicle then arrived and we drove it just 15 feet before that vehicle provided a false positive alarm in our driveway. This occurred at a accelerate of about 10 MPH while facing a clear 200-foot driveway ahead. sadly, this is not uncommon .
One of our staff reports, “ I get the false warnings, possibly 35 percentage of the fourth dimension I test a vehicle. There will be literally nothing in movement of me, or it ’ south reading something slightly left or correct as being in front of me. ” Another reports, “ I ’ ve had the admonitory light flare for no reason a few times over the end three years, but the brakes have never applied. ” Another says, “ I have never had brakes apply randomly going ahead without a good reason. ” Our West Coast team member, Philip Ruth reports that his trial sphere poses a unique challenge to AEB systems.

Our test and the two new NHTSA recalls do indicate that these systems are not all the same and are not even perfected. Jessica Cicchino, IIHS vice president for research and an AEB study co-author says that such systems should be criterion equipment, but that, “ …designers have to be mindful not to build in sensitivities that would irk drivers or put them in potentially hazardous situations by intervening in situations in which the driver is in command of the vehicle. ” We feel that automakers should continue to offer the systems, but should be argus-eyed regarding reports of trouble and communicate better with owners when trouble does arise. These systems have been proven to reduce accidents. however, if the populace or regulators lose confidence in them due to real-world failures, the backfire could be significant .
