Embodiment 1

[0024] figure 1 It is a functional block diagram of the intelligent switching system of the automobile headlight of the present invention.

[0025] In this example, if figure 1 As shown, this embodiment provides a system for intelligently switching far and near beams of automobile headlights, which includes: a control module, a light intensity acquisition module electrically connected to the control module, and a far and near light switching module; wherein the light intensity acquisition The module is adapted to collect light intensity data in the current environment and send it to the control module, that is, when the light intensity data is within the low beam range, the control module is adapted to control the far and low beam switching module to turn on the low beam lights; and when the light intensity data is within the high beam range, the control module is adapted to control the high and low beam switching module to turn on the high beam.

[0026] In this embodiment,...

Embodiment 2

[0048] figure 2 It is a flow chart of the method for intelligently switching high and low beams of automobile headlights of the present invention.

[0049] On the basis of the above examples, if figure 2 As shown, the present embodiment provides a method for intelligently switching the far and near beams of automobile headlights, which includes: after collecting the light intensity data in the current environment, switching the corresponding lights according to the light intensity data; detecting the distance data between the vehicle and the objects around the vehicle, And according to the distance data, when it is judged that there is an object approaching, switch to the low beam light, and after judging that the object is far away, switch to the original light; and obtain the overtaking signal and / or acceleration signal of the vehicle, and judge the vehicle is in an overtaking state based on the distance data , switch to the low beam, and switch to the original light afte...

Abstract

The invention relates to an automobile headlamp intelligent high-low beam switching system and switching method. The automobile headlamp intelligent high-low beam switching system comprises a controlmodule, an illumination intensity collection module and a high-low beam switching module; when illumination intensity data are within a low beam threshold, the control module controls the high-low beam switching module to turn on a low beam; and when the illumination intensity data are within a high beam threshold, the control module controls the high-low beam switching module to turn on a high beam. According to the automobile headlamp intelligent high-low beam switching system, by collecting the illumination intensity data under a current environment, judging and switching corresponding lights according to the illumination intensity data, accurately switching high and low beams in advance during meeting, overtaking, being overtaken and meeting pedestrians and obstacles and switching to arequired state (high beam or low beam) after finishing processes such as meeting, overtaking, being overtaken and crossing over the pedestrians and the obstacles, the intelligent high-low beam switching problem of an automobile running in dark regions (pavements with poor illumination at nights) is solved, and the running safety is enhanced.

Description

technical field [0001] The invention relates to the field of automobile intelligent control, in particular to an automobile headlight intelligent switching system for switching far and low beams and a switching method. Background technique [0002] Most modern cars are equipped with automatic headlights, but many nighttime accidents are caused by the oncoming vehicle with its high beams on. Because the oncoming vehicle has its high beams on, the driver's eyes will be blinded by the light on the opposite side. less than the road conditions ahead. When overtaking, your own high beam will completely reflect the rearview mirror of the vehicle in front, and the former driver cannot see anything. When being overtaken, your own rearview mirror will be completely reflected by the light of the overtaking vehicle. Can’t see anything, this is a very dangerous situation, the previous cars required the driver to manually switch the high and low beams, but sometimes the driver would forg...
