Lane Game: Lane Guidance Systems Are Now Emerging onto the Vehicle Market

This article describes the difficulties in developing an automotive lane guidance system, as well as Volvo's possible solution. Lane guidance aims to keep drivers from drifting into another lane by monitoring lane markings with a vision system that alerts the driver with an audio warning, a vibration, or a small amount of steering wheel torque to keep the vehicle in the lane. The difficulties in making such systems work, however, are many: false alarms when changing lanes intentionally, curve cutting by drivers, or driver reliance on a system while they changed CDs or checked text messages. The article describes in detail how Volvo is evaluating a system that shows promise.
