AAA finds flaws in driver assistance technologies
A study by the American Automobile Association has found flaws in blind spot monitoring and lane departure warning systems. Among the problems are delayed warnings by the blind spot monitoring technology and lane departure warning systems that failed to track the lane under certain road conditions.
Researchers found that:
« Blind-spot monitoring systems had difficulty detecting fast moving vehicles, such as those merging onto a busy highway. Alerts were often provided too late to be useful.
« Worn pavement markers, construction zones and intersections can cause the lane departure warning system to lose track of lane location.
« Motorcycles were detected by blind spot monitoring systems 26 percent later than passenger vehicles.
« The alerts and warnings emitted by the systems could be similar to other advanced driver assistance features, causing confusion.
Some blind-spot monitoring systems we tested had short detection range, which meant that a vehicle was already in the blind spot before the alert came on, says Megan McKernan, manager of automotive engineering at the Automobile Club of Southern California. The lane departure warning system on several vehicles showed false positives and missed some warnings. The driver might elect to disable the system, which is permissible.Download Bulletin PDF
