Infiniti to Equip SUV with Lane Departure Warning System
Infiniti announced on April 1 that later this fall a new Lane Departure Warning (LDW) system, which alerts drivers of an unintended movement out of their traffic lane, would be offered on 2005 models of Infiniti's FX crossover sport/utility vehicle — the first production application of LDW in North America.The system, which uses a camera, a speed sensor, an indicator and an audible warning buzzer, will also be available on the next-generation M45 performance luxury sedan, scheduled to go on sale in spring 2005 as a 2006 model.The LDW system is temporarily disabled by driver activation of the vehicle's turn signals, which informs the system's control unit of intended lane changes. The system also features a manual cancel switch, which allows the driver to turn it off when desired. The system automatically resets when the vehicle is restarted.The system recognizes lane markings through the use of a small camera mounted behind the rearview mirror. The camera's signal and the vehicle's speed are sent to the system's microprocessor. A judgment is then made as to whether the vehicle is moving out of the lane (depending on the distance and lateral velocity to the lane).
