INFINITI pioneered Lane Departure Warning on the 2005 INFINITI FX, designed to help address the National Highway Traffic Safety Administration's (NHTSA) findings that showed more than half of all traffic fatalities were due to some type of lane departure. INFINITI then expanded and enhanced its warning system with the world's first Lane Departure Prevention system on the 2008 INFINITI M, which helps the driver bring the vehicle back into the lane of intended travel.
Working in conjunction with the world's first steer-by-wire system in a production car - Direct Adaptive Steering (DAS) - INFINITI incorporated three separate systems that help drivers avoid dangerous "lane drift." Using a small camera installed in front of the rear view mirror that detects lane markers in the road, Lane Departure Warning (LDW) alerts drivers with an audible and visual warning when he or she starts to drift out of a lane while driving at certain speeds. If the driver does not heed LDW's warning, Lane Departure Prevention (LDP) provides the next layer of protection helping to ease the vehicle back toward the center of the lane by providing small electronic steering input changes on vehicles equipped with DAS.
