This application provides an intelligent light switching method and system, and a related device. One example method includes: The intelligent light switching system obtains an image, where the image comprises lamp source information; calculates an ambient light brightness value corresponding to the image; classifies, based on the lamp source information, a lamp source included in the image to obtain a classification result; and switches to a high beam or a low beam based on the ambient light brightness value corresponding to the image and the classification result.

A method for controlling headlights of a motor vehicle, including capturing of environment data of a surroundings of the motor vehicle using sensors of the motor vehicle, wherein the surroundings comprise a road on which the motor vehicle is traveling, detection using the environment data to determine whether street lighting system independent of the motor vehicle is present, detection using the environment data to determine whether there are trees next to the road, and setting of a brightness of the headlights using the results of the detections.
