US 10,766,403 B1 · Vehicle headlamp lighting strategy

Abstract

A method includes generating a first beam pattern via a headlamp assembly arranged on a motor vehicle and detecting, via a camera, an object in the first light beam pattern. The method additionally includes receiving, via an electronic controller, a signal from the camera indicative of the object, identifying the object as another motor vehicle, and determining a distance between the headlamp assembly and the other vehicle. The method also includes determining a first amount of glare the first beam pattern generates to the other vehicle at the determined distance and identifying when the first amount of glare exceeds target glare. The method further includes identifying a second beam pattern corresponding to a second amount of glare that is below the target glare and switching the headlamp assembly from generating the first beam pattern to generating the second light beam pattern.

A method of operating a headlamp assembly arranged on a first motor vehicle, the method comprising:

generating, via the headlamp assembly, a first beam pattern;
detecting, via a camera, an object in the first beam pattern;
receiving, via an electronic controller, a signal from the camera indicative of the detected object and identifying the detected object as a second motor vehicle;
determining, via the electronic controller, a distance between the headlamp assembly and the second motor vehicle using the signal from the camera;
determining, via the electronic controller, a first amount of glare the first beam pattern generates to the second motor vehicle at the determined distance, and identifying when the first amount of glare exceeds a target glare;
identifying, via the electronic controller, a second beam pattern corresponding to a second amount of glare that is below the target glare;
and
regulating the headlamp assembly, via the electronic controller, to switch from generating the first beam pattern to generating the second beam pattern.

5 more elements

A motor vehicle comprising:

a headlamp assembly configured to provide illumination ahead of the motor vehicle;
a camera configured to detect a view of a terrain;
and
an electronic controller in communication with the headlamp assembly and the camera and configured to:
regulate the headlamp assembly to generate a first beam pattern;
receive a signal from the camera indicative of a detected object and identify the detected object as another motor vehicle detected in the first beam pattern;
determine a distance between the headlamp assembly and the other motor vehicle using the signal from the camera;
determine a first amount of glare the first beam pattern generates to the other motor vehicle at the determined distance, and identify when the first amount of glare exceeds a target glare;
identify a second beam pattern corresponding to a second amount of glare that is below the target glare;
and
regulate the headlamp assembly to switch from generating the first beam pattern to generating the second beam pattern.
