GPS Anti-Dazzling System and Method for Vehicles
First Claim
1. A global positioning system (GPS) anti-dazzling system for vehicles, the system comprising:
- a windshield polarization plate installed on a windshield of a vehicle, and transmitting a light polarized in a direction determined by an electric signal;
a polarization information storing unit storing driveway information on a map, and storing polarization information including the polarization direction of the windshield polarization plate that is set in advance to prevent driver'"'"'s dazzling according to a location of the driveway and a driving direction;
a GPS unit sensing a location and a driving direction of the vehicle, and acquiring the polarization information from the polarization information storing unit according to the sensed location and the driving direction; and
a polarization controller controlling the polarization direction of the windshield polarization plate according to the polarization information transmitted from the GPS unit.
