SYSTEM AND METHOD FOR CONTROLLING HEADLAMPS OF VEHICLE
First Claim
1. A method for controlling high-beam lamp state in a vehicle, the method comprising:
- activating the high-beam lamp state of the vehicle;
receiving a first output signal from a high-beam sensor, the first output signal being indicative of an intensity of light from a light source facing the vehicle;
receiving a second output signal from a stray light sensor, the second output signal being indicative of an intensity of stray light from a stray light source in vicinity of the vehicle;
receiving a speed signal from a ground speed sensor associated with the vehicle, the speed signal being indicative of a ground speed of the vehicle; and
selectively deactivating the high-beam lamp state of the vehicle based on at least one or more of the first output signal, the second output signal, and the speed signal.

Abstract
A method for controlling high-beam lamp state in a vehicle is disclosed. The method includes activating the high-beam lamp state of the vehicle. Further, the method includes receiving a first output signal from a high-beam sensor, the first output signal being indicative of an intensity of light from a light source facing the vehicle. The method includes receiving a second output signal from a stray light sensor, the second output signal being indicative of an intensity of stray light from a stray light source in vicinity of the vehicle. The method includes receiving a speed signal from a ground speed sensor associated with the vehicle, the speed signal being indicative of a ground speed of the vehicle. Furthermore, the method includes selectively deactivating the high-beam lamp state of the vehicle based on at least one or more of the first output signal, the second output signal, and the speed signal.

11. A controller for an auto-dipping system associated with a head lamp of a vehicle, controller configured to:
-
detect activated high-beam lamp state of the vehicle; receive a first output signal from a high-beam sensor, the first output signal being indicative of an intensity of light from a light source facing the vehicle; receive a second output signal from a stray light sensor, the second output signal being indicative of an intensity of stray light from a stray light source in vicinity of the vehicle; receive a speed signal from a ground speed sensor associated with the vehicle, the speed signal being indicative of a ground speed of the vehicle; and selectively deactivate the high-beam lamp state of the vehicle based on at least one or more of the first output signal, the second output signal, and the speed signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
