Car light control system and method

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.
