LDW (Lane Departure Warning)
From FOT-Net WIKIJump to navigationJump to search
Lane Departure Warning (LDW) assists the driver to maintain his/her lane position, giving a warning if the vehicle crosses lane markings unintentionally. The warning can be acoustic or haptical (vibration or small torque on the steering wheel or driver’s seat). The system maintains the vehicle position by detecting lane markings or street boundaries via a video sensor. A warning occurs only above a certain minimum speed. Specific driver actions, e.g. setting the indicator, suppress the warning. The system is intended to operate on highways or equivalent roads, and can if necessary be switched off by the driver.
