Car light control system and method

Abstract

The invention discloses a car light control system and method. The system comprises a light source body module, a space light modulator module, an image sensing module and a central control module. The space light modulator module receives light emitted by the light source body module and emits the light through a digital micro mirror device, the image sensing module acquires images of external objects lighted by the light, the central control module analyzes the acquired images and sends control instructions to the space light modulator module according to an analysis module, and the space light modulator module adjusts the overturning angle of each micro lens in the digital micro mirror device according to the received control instructions to enable the quantity and the angle of the emitted light to be changed, such that a corresponding headlight illumination mode is dynamically adjusted according to real-time road conditions including light conditions, rain and snow weather, sharp turns, steep slopes and the like in front of a vehicle, an optimal road illumination effect is provided for a driver, and the driving safety is improved.

Description

technical field [0001] The invention relates to the field of control, in particular to a vehicle light control system and method. Background technique [0002] Car headlights, from early acetylene lamps, to halogen tungsten lamps, xenon lamps, to today's LED lights and laser lights, the development of car headlights has made great progress. [0003] However, at present, the control of automobile headlights is mostly limited to the lighting and extinguishing of the lights. Usually, different lighting modes cannot be turned on in real time according to different road condition information, which reduces the driving experience and driving safety of the driver to a certain extent. Contents of the invention [0004] In view of this, the present invention provides a vehicle light control system and method, which can dynamically adjust the lighting mode of the headlights by acquiring driving information such as weather environment, road surface changes, and intersection lights in...
