Abstract: Described herein is a system and method that recognizes vehicle lane departure in road conditions affected by environmental conditions. The system uses magnetic field flux detection to determine if a vehicle is departing from a projected vehicle trajectory or a determined vehicle position between lanes. A magnetic material is applied to the stripes painted on road surfaces or on other applicable lane boundary indicators. The system uses magnetic field flux sensors or Hall Effect sensors mounted in the vehicle to recognize changes in magnetic field flux from the magnetized road stripe. These changes in magnetic field flux are interpreted by the system to determine whether alarms should be initiated for vehicle lane departure.
