Embodiment 1

[0085] Embodiment one (when the driving road ahead is an uphill road):

[0086] The infrared light source of the infrared spotlight 1 emits infrared stripes (also equivalent to infrared light waves), and the infrared stripes can be reflected to the shielding mechanism 12 through the reflector 13, and the infrared spotlight 1 of the automobile is arranged with a shielding mechanism 12 with strip-shaped light holes. After the car lamp infrared stripe shielding mechanism 12 and the lens 15, it changes into horizontal stripes with intervals between light and dark. Projected onto the road surface to form a light pattern of horizontal stripes with light and dark intervals, and the camera 2 takes pictures.

[0087] When the horizontal stripes shine on the road in front of the vehicle, the continuous zebra pattern will be distorted and deformed with the ups and downs of the road. The real-time horizontal stripe shape of the road surface is collected by the camera 2, and the stripe sh...

Embodiment 2

[0090] Embodiment two (when the driving road ahead is a downhill road):

[0091] The infrared light source of the infrared spotlight 1 emits infrared stripes (also equivalent to infrared light waves), and the infrared stripes can be reflected to the shielding mechanism 12 through the reflector 13, and the infrared spotlight 1 of the automobile is arranged with a shielding mechanism 12 with strip-shaped light holes. After the car lamp infrared stripe shielding mechanism 12 and the lens 15, it changes into horizontal stripes with intervals between light and dark. Projected onto the road surface to form a light pattern of horizontal stripes with light and dark intervals, and the camera 2 takes pictures.

[0092] When the horizontal stripes shine on the road in front of the vehicle, the continuous zebra pattern will be distorted and deformed with the ups and downs of the road. The real-time horizontal stripe shape of the road surface is collected by the camera 2, and the stripe s...

Abstract

The invention provides an automobile headlamp capable of achieving automatic regulation of the height and an automatic height regulating method and relates to the technical field of automobiles. The automobile headlamp t comprises an infrared spot lamp, a camera, an image processor and a headlamp module; the infrared spot lamp is used for projecting an infrared fringe on a driving pavement, and the infrared fringe is composed of horizontal strip-shaped fringes which are spaced in light and shade; the infrared fringe can form a corresponding distorted fringe along with the change of a pavementoutline; the camera is used for acquiring image information of the distorted fringe formed by projecting the infrared fringe on the pavement outline; the image processor is connected with the camera by data and is used for acquiring the image information and generating a height regulation command according to the image information; and the headlamp module is connected with the image processor by data and is used for acquiring the height regulation command and regulating the headlamp irradiation height of the headlamp module according to the height regulation command.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile headlight with automatic height adjustment and a height automatic adjustment method. Background technique [0002] With the continuous development and updating of modern technology, more and more intelligent products appear in our daily life. As a concentrated product of high technology, automobiles are becoming more and more intelligent. The technological content of automobile headlights often represents the safety of automobiles. [0003] Adjustable height of the headlight means that the headlight can adjust the horizontal irradiation height of the light. Now more and more models have manual adjustment knobs inside, which can manually adjust the irradiation height of the headlights, and even the headlights of some high-end luxury cars can automatically adjust the height of the headlights through sensors. If this function plays a certain role in driving safet...
