Lane Departure Mitigation

Hours Posted on Hours Updated on

How does it work?

This technology consists of the identification of limits or edges where the vehicle travels on the road, and constantly returns the vehicle to within these limits if the system is active. These markings on the road are what allow it to operate. Generally, prior to this function being activated, a warning alert in the form of a sound, vibration or light, is given and if it is not responded to by the driver, the technology gently brings the vehicle back into the lane.
