The invention relates to an anti-reflection film for a visible light wave band and a design method and a preparation method thereof. The anti-reflection film comprises a substrate which is white glass; the thin film stack is formed on at least one side of the substrate, the thin film stack is formed by stacking at least seven thin film layers, the thin film layers are selected from a low-refractive-index material and a high-refractive-index material of a visible light wave band, and the thin film stack is integrally formed in a mode that the low-refractive-index material and the high-refractive-index material are alternately combined; wherein the physical thickness sequence of all the thin film layers of the thin film stack is a non-periodic sequence. The reflectivity is less than or equal to 0.5% and the transmittance is more than or equal to 98% in the whole visible light wave band.

The purpose of the present invention is to suppress glare to people due to reflection of pattern light from a road surface drawing device on an icy road surface. A road surface drawing device for a vehicle is provided with: a road surface drawing lamp for irradiating pattern light; and a controller for controlling the road surface drawing lamp. The controller determines a plurality of conditions including a first condition, a second condition, and a third condition. The first condition is that the illuminance outside the vehicle is equal to or less than a predetermined illuminance ILth. The second condition is that the outside air temperature of the vehicle is equal to or less than the predetermined temperature Tth. The third condition is that the traction control TRC operates a predetermined number of times N1th or more within the predetermined time t1th, and the lateral slip suppression control ESC operates a predetermined number of times N2th or more within the predetermined time t1th. When the plurality of conditions are satisfied, the controller executes glare reduction control for stopping irradiation of at least a portion of the pattern light, reducing the amount of light, or changing the manner.

This invention discloses a vehicle roof lighting system that adaptively adjusts based on driving lighting needs, belonging to the field of vehicle lighting technology. It includes a road condition recognition module, a vehicle status acquisition module, a central control module, a lighting execution module, an anti-glare coordination module, and a human-machine interaction module. The road condition recognition module acquires geological texture features, geometric contour information, and ambient light intensity within a preset range in front of the vehicle, generating a multi-dimensional semantic map. The vehicle status acquisition module monitors the vehicle's dynamic parameters and dynamic pose in real time, performs noise reduction preprocessing on the raw sensor data, and outputs vehicle driving posture parameters. Through a multi-sensor layout, Kalman filtering algorithm, and multi-degree-of-freedom mechanical actuators, it meets the urgent need for high-quality auxiliary lighting for off-road vehicles in complex and dynamic driving environments, significantly improving driver visibility safety. Simultaneously, through intelligent anti-glare coordination logic, it enhances road traffic safety.
