CR believes these systems should come with all trim levels, given their ability to save lives. Nissan updated the software in some of its 2017-2018 Rogue SUVs to address false braking, And both Tesla and Mazda have recalled cars to fix unexpected AEB application.ĬR’s take: FCW and AEB are available in most new cars, but the two safety features are still not yet standard equipment across the industry. The National Highway Traffic Safety Administration (NHTSA) is investigating complaints of unexpected braking in some 2017-2019 Honda vehicles. ![]() Some systems have been a little overzealous in deciding when to hit the brakes. “Never rely on these systems to work perfectly, and always stay vigilant.” “It’s important to remember these systems are using cameras and sensors that can get dirty, blinded by sunlight, or obscured in the rain,” Funkhouser says. And studies show that AEB with pedestrian detection can’t always see pedestrians and cyclists at night or in turns. Even high-speed AEB systems can only slow a car down in some cases, mitigating a crash rather than preventing it. “They are designed to only activate at the last possible second, so it’s common to have never experienced an AEB event." Our survey respondents tended to agree, with a majority of owners telling us they were “very satisfied” with their AEB systems.īut it’s important to remember that AEB isn’t foolproof and that today’s AEB systems can’t prevent all collisions. “The best AEB systems are the ones you never notice until you need them most,” says Kelly Funkhouser, manager for vehicle technology at CR. The survey covered about 47,000 vehicles. Respondents answered questions about their satisfaction with the systems. In our most recent survey, we asked CR members to rate their experiences with the advanced safety and driver-assistance systems on their 2017-2022 cars. Rear automatic emergency braking (AEB-rear): Brakes are automatically applied to prevent a collision or reduce impact force while the car is traveling in Reverse. Other AEB systems can work at highway speeds, which are typically above 55 mph. Some AEB systems operate only at city speeds, which are typically at 55 mph and below. Data from the Insurance Institute for Highway Safety (IIHS) shows that rear-end collisions are cut by 50 percent for vehicles equipped with AEB and forward collision warning (FCW).Īutomatic emergency braking (AEB): Detects potential collisions with a vehicle ahead, provides forward collision warning, and automatically brakes to avoid the collision or lessen the severity of impact.Īutomatic emergency braking with pedestrian detection (AEB-ped): Detects potential collisions with pedestrians or bicyclists while the car is traveling forward and automatically brakes to avoid the collision or lessen the severity of impact. Some systems apply only a portion of the braking power, so drivers will want to apply the full brakes as well. ![]() But if a car equipped with AEB senses an imminent collision and the driver doesn’t react in time, the car starts braking on its own. ![]() Anti-lock braking systems (ABS) use wheel sensors to maximize braking action and prevent wheels from locking up and a car from skidding. We’re often asked, "Is AEB the same thing as ABS?" Both technologies have to do with braking, but that’s where the similarity ends. ![]()
