SMART BEAM LIGHTS FOR DRIVING AND ENVIRONMENT ASSISTANCE
In certain embodiments, a vehicle headlight system can include at least two independently controlled headlights that can be configured such that a first headlight can be oriented toward a first point-of-interest (POI) and, at the same time, a second headlight can be oriented toward a second POI that is different than the first POI. Some POIs can include various road features (e.g., road contours), signs, moving objects (e.g., people, animals), and the like. The vehicle headlight system can further control various operating characteristics of the one or more headlights including brightness, color, and illumination pattern, to name a few. In some cases, environmental data (e.g., road pitch, roll, and yaw data) and vehicle data (e.g., velocity and acceleration data) can be used to determine which direction to orient the headlights to maintain a proper illumination of the road ahead.
1 . A vehicle headlight system for a vehicle comprising:
a first headlight having a first control system to control an orientation of the first headlight;
a second headlight having a second control system to control an orientation of the second headlight; and
a processor to control the first and second control systems,
wherein the processor is operable to orient the first headlight toward a first point-of-interest (POI), and simultaneously orient the second headlight toward a second POI that is different than the first POI.
2 . The vehicle headlight system of claim 1 wherein the first POI and the second POI each include at least one of a road feature, a sign, or a moving object.
3 . The vehicle headlight system of claim 1 wherein the processor further controls:
a brightness of each of the first and second headlights;
a color of each of the first and second headlights; and
an illumination pattern of each of the first and second headlights.
4 . The vehicle headlight system of claim 1 wherein the first and second control systems are actuator systems to control the orientation of the first and second headlight in two axes of rotation.
5 . The vehicle headlight system of claim 1 further comprising:
a global position system (GPS) to receive position data corresponding to:
a location of the vehicle; and
POI data,
wherein the processor uses the POI data, at least in part, to orient the first or second headlight when the first or second POI in included in the POI data.
6 . A method of operating a vehicle headlight system for a vehicle, the method comprising:
receiving, by a processor, a first sensor input corresponding to a location of a first point-of-interest (POI);
receiving, by the processor, a second sensor input corresponding to a location of a second point-of-interest (POI);
simultaneously controlling, by the processor:
a focus of a first adjustable headlight toward the first POI; and
a focus of a second adjustable headlight toward the second POI,
wherein the first POI is different than the second POI.
7 . The method of claim 6 wherein the first POI and the second POI each include at least one of a road feature, a sign, or a moving object.
8 . The method of claim 6 further comprising:
simultaneously controlling, by the processor, at least one of:
a brightness of each of the first and second adjustable headlights;
a color of each of the first and second adjustable headlights; or
an illumination pattern of each of the first and second adjustable headlights.
9 . The method of claim 6 further comprising:
receiving, by the processor from a GPS, position data corresponding to a location of the vehicle, and POI data,
wherein the controlling of the first and second adjustable headlights is based, in part, on the POI data.
10 . The method of claim 6 wherein the first and second adjustable headlights are controlled by actuator systems to control the focus of the first and second headlight in two axes of rotation.
11 . A method of operating a vehicle headlight system for a vehicle, the method comprising:
detecting, by a sensor controlled by a processor, light reflected from a POI;
determining, by the processor, a visibility of the POI based on the light reflected from the POI; and
changing a color of an adjustable headlight to improve the visibility of the POI.
12 . The method of claim 11 further comprising:
receiving, by a processor, a sensor input corresponding to a location of the POI; and
controlling, by the processor, an orientation of the adjustable headlight toward the POI.
13 . The method of claim 11 further comprising:
determining, by the processor, one or more colors associated with the POI based on the light reflected from the POI; and
determining, by the processor, a color that, when combined with the one or more colors associated with the POI, improves the visibility of the POI,
wherein changing the color of the adjustable headlight includes changing the color to the determined color.
