Mobileye N.V. has announced that they are supplying Lane Departure Warning technology for select high-end General Motors vehicles. It is an advanced, intelligent driver assistance system, based on a forward-looking camera combined with Mobileye's EyeQ™ advanced vision processing chip that warns motorists before they drift inattentively across a marked lane.
The intelligent Lane Departure Warning (LDW) technology was engineered for General Motors through a partnership between Mobileye and the automotive supplier Magna Electronics. Both the technology and the system were tested extensively over the past few years on a wide range of weather conditions, roads, and lane marking types. The system is based on Mobileye's advanced algorithm technology for video-based lane marking recognition, and using Mobileye's Vision System on a Chip, Mobileye EyeQ™ as the vision processing platform with a high dynamic range digital CMOS camera.
According to statistics from the U.S. Transportation Research Board approximately 40 percent of all road fatalities occur when a single vehicle departs from the road and crashes. Rumble strips have reduced lane departure fatalities by up to 90 percent, and at times even more. "By using an audible warning, GM's new lane departure warning system creates an intelligent rumble strip imitation that provides drivers with an advanced lane departure warning even when there are no physical strips on the shoulder of the road,” explains Amnon Shashua, Ph.D., Chairman and Chief Scientist of Mobileye N.V.
“The advanced LDW intelligence is superior to basic lane departure warning systems that warn you at the instant that you’re crossing the lane marking.”, Shashua says. "The GM LDW prevents accidents by alerting drivers prior to lane change that they are edging close to the lane mark without using their turn signal. If you’re already crossing the line, it may be too late for a warning.”. The GM LDW vision system warns of potential lane departure by providing a directional audio alert, emitted from the vehicle's sound system, according to the direction of the deviation. The directional audio warning is combined with a visual indication, both urging the driver to correct their steering, and keep their vehicle in the lane. System availability is shown through a display in the instrument cluster. Mobileye's LDW technology for GM offers one of the few systems worldwide that demonstrate “single lane marking availability” where a single lane marking is sufficient for alerting, in contrast to systems that require lane markings on both sides. It can also detect construction areas or other situations where lane markings are ambiguous.
According to Dr. Shashua, LDW will help motorists stay safe in diverse driving conditions including monotonous highways, where driver inattention is commonplace, as well as on curved roads. "Moreover,", adds Shashua, "the intelligence of the system allows it to refrain from issuing unnecessary warnings, when there is clear indication the driver is aware of the situation. This takes effect in holding back the LDW alert upon sharp steering wheel maneuvers, as well as upon significant pressing of the accelerator pedal – actions that are indicative of driver awareness, for example, when performing an over-taking."
The new feature can be ordered as an option in the 2008 Cadillac STS, Cadillac DTS, and Buick Lucerne models.
