"You can then introduce algorithms that predict where the object is going and whether it is likely to move into the path of the car," Avery explains. Comparing the Volkswagen Golf Mk7, which has AEB fitted as standard to all but the entry-level S trim, with the previous Mk6 model, Thatcham found there was a 45% reduction in crashes where injuries occurred.Ĭombining the two technologies (or using more than one camera) allows objects to be precisely located and identified. Thatcham has closely monitored the effectiveness of AEB. In contrast, the fitment of lane departure warning systems had little effect on insurance claims. For cars fitted with AEB systems, it found that insurance claims to repair damage done by the studied car to another vehicle were reduced by 10-14%. One study by the US insurance industry compared the effectiveness of AEB with other driver assistance and collision avoidance technologies. Instead of the 0.5-0.6G of braking force delivered by an early AEB device, modern systems can deliver around 1G. Today’s AEB systems aren’t only smarter, they also brake harder. "Software has improved and car makers now have more confidence in their systems," explains Matthew Avery, director of research at Thatcham. Now AEB systems use radar and cameras or a combination of both to enable braking from higher speeds and much greater sophistication. The original City Safety system used a LIDAR (light detection and ranging) sensor. Technology has moved on a great deal since 2008. If there was a greater difference in closing speed, the system would reduce the severity of an impact if it couldn't prevent it altogether. Operating from just over 2mph to just under 19mph, the first generation of City Safety would prevent collisions entirely if the difference in the speed of the two vehicles involved was no more than 9mph. As the name implies – and like most early AEB systems – City Safety was developed to prevent crashes during urban driving at low speeds. Volvo was one of the pioneers, launching a system called City Safety in the XC60 SUV in 2008. The very best systems – those that earn the most points in Euro NCAP crash tests – can detect cyclists and pedestrians as well as cars.ĪEB, which uses the same technology that underpins adaptive cruise control and applies it to improve safety, has actually been around for many years. More sophisticated systems work across a wider speed range, so they protect against more serious accidents where there is the potential for severe injury or death. ![]() The most basic AEB systems work at low speeds to prevent or reduce the severity of minor urban collisions. If the driver fails to take action, the automatic or ‘autonomous’ part of the system will kick in and apply the brakes automatically. ![]() The system will usually start by warning the driver, using a dashboard message or an audible alarm, that a collision is likely and that they need to brake. All AEB systems use sensors to detect obstacles ahead and assess whether a collision is likely. ![]()
