Abstract

A vehicle light system includes a plurality of light banks connected to a vehicle and configured to project light that radiates away from the vehicle. Each light bank includes a plurality of light sources. An image sensor, such as a camera, is connected to the vehicle and is configured to generate image data corresponding to a scene about the vehicle. A controller is connected to the light banks and the image sensor. The controller is configured to receive the image data, and execute an object detection machine learning model based on the image data to detect an object, determine a location of the object, and classify the detected object. The controller is configured to then select and dim one or more of the plurality of light sources based on the output of the object detection machine learning model. The dimming can vary based on the object class.

First claim

What is claimed is:

1. An adaptive lighting system for a vehicle, the adaptive light system comprising:
a plurality of light sources connected to a vehicle and projecting light that radiates fully or partially around and away from the vehicle;
one or more sensors connected to the vehicle and configured to generate image data corresponding to a scene about the vehicle; and
a controller communicatively connected to the light sources and the one or more sensors, wherein the controller is configured to:
receive the image data generated by the one or more sensors;
execute an object detection machine learning model on the image data to (i) detect an object in the image data, (ii) determine a relative location of the detected object, and (iii) classify the detected object to determine a class of the detected object; and
selectively dim, at various dim levels, a selected one or more of the plurality of light sources, wherein the selected one or more of the plurality of light sources is selected by the controller based upon the determined location and class of the detected object, and wherein the controller is configured to selectively dim, at various dim levels, the selected one or more of the plurality of light sources by a magnitude depending on the determined class of the detected object.

2. The adaptive lighting system of claim 1 , wherein the controller is configured to dim the one or more of the plurality of light sources to (i) a first light intensity based on the detected object being of a first class, and to (ii) a second light intensity based on the detected object being of a second class.

3. The adaptive lighting system of claim 1 , wherein the magnitude of dimming is less than 100 percent of maximum illumination.

4. The adaptive lighting system of claim 1 , wherein the selected one or more of the plurality of light sources includes a first group of light sources and a second group of light sources, wherein the controller dims the first group to a first brightness, and the controller dims the second group to a second brightness different than the first group.

5. The adaptive lighting system of claim 1 , wherein the controller is configured to execute the object detection machine learning model on the image data to determine a distance to the detected object, wherein the magnitude of dimming is based on the distance.

6. The adaptive lighting system of claim 1 , wherein the plurality of light sources includes (i) a first light source that creates a tunnel of darkened light, and (ii) a second light source adjacent to the first light source;
wherein the controller is configured to dim the first light source to a first brightness, and dim the second light source to a second brightness brighter than the first brightness to alter the tunnel created by the first light source.

7. The adaptive lighting system of claim 1 , wherein the one or more sensors includes at least one of a camera, lidar sensor, radar sensor, ultrasonic sensor, GPS sensor, and V2X sensor.

8. The adaptive lighting system of claim 1 , further comprising a wireless transceiver configured to receive V2X data indicative of one or more objects about the vehicle including the detected object;
wherein the controller is further configured to select the one or more of the plurality of light sources for dimming based on the V2X data.

9. The adaptive lighting system of claim 1 ,
wherein the controller is further configured to process the image data to estimate an amount of light reflecting off the object, and adjust the magnitude of dimming of the selected one or more of the plurality of light sources based on the estimated amount of light reflecting off the object.

10. An adaptive lighting system comprising:
a plurality of light sources configured to project light that radiates fully or partially around;
a wireless transceiver configured to receive V2X data indicative of one or more objects; and
a controller communicatively connected to the plurality of light sources and the wireless transceiver, wherein the controller is configured to:
receive the V2X data from the wireless transceiver;
based on the V2X data, determine a relative location of the one or more objects;
based on the V2X data, determine a distance to the one or more objects; and
dim a selected one or more of the plurality of light sources, wherein the selected one or more of the plurality of light sources is selected by the controller based upon the determined location of the one or more objects, and wherein the controller is configured to dim the selected one or more of the plurality of light sources by a magnitude depending on the determined distance to the one or more objects.

11. The adaptive lighting system of claim 10 , further comprising one or more image sensors configured to generate image data corresponding to a scene about the vehicle;
wherein the controller is further configured to execute an object detection machine learning model on the image data to (i) detect one of the one or more objects and (ii) classify the detected object to determine a class of the detected object;
wherein the controller is further configured to adjust the magnitude of dimming of the selected one or more of the plurality of light sources based on the determined class of the detected object.

12. The adaptive lighting system of claim 11 , wherein the controller is configured to dim the one or more of the plurality of light sources to (i) a first light intensity based on the detected object being of a first class, and to (ii) a second light intensity based on the detected object being of a second class.

13. The adaptive lighting system of claim 10 , wherein the magnitude of dimming is between 0 and 99 percent of maximum illumination.

14. The adaptive lighting system of claim 10 , wherein the selected one or more of the plurality of light sources includes a first group of light sources and a second group of light sources, wherein the controller dims the first group to a first brightness, and the controller dims the second group to a second brightness different than the first group.

15. The adaptive lighting system of claim 10 , wherein the plurality of light sources includes (i) a first light source that creates a zone of darkened light, and (ii) a second light source adjacent to the first light source;
wherein the controller is configured to dim the first light source to a first brightness, and dim the second light source to a second brightness brighter than the first brightness to alter the zone of darkened light created by the first light source.

16. A method of controlling a lighting system, the method comprising:
lighting a plurality of light sources to project light that radiates away therefrom;
receiving image data from an image sensor;
determining a location of the object based on the image data;
executing an object detection machine learning model on the image data to classify the object detected in the image data to determine a class of the detected object; and
