Embodiment 1

[0060] In the embodiment of the present invention, the execution subject of the control method of light brightness may be a processor to obtain a controller, and the execution flow of the control method is as follows: figure 1 shown, including:

[0061] S101. When it is recognized that the position of the obstacle in front of the target vehicle moves, acquire the position information of the obstacle;

[0062] In the embodiment of the present invention, when the camera installed on the target vehicle recognizes that the obstacle in front moves during the driving process of the target vehicle, the running information of the target vehicle is obtained, and the obstacle position information contained in the running information is obtained.

[0063] S102. Determine the target light pattern control instruction according to the obstacle position information, wherein the target light pattern control instruction includes the adjustment direction of the brightness, the brightness target v...

Embodiment 2

[0071] In the embodiment of the present invention, in order to avoid dazzle, the control method further includes figure 2 Steps shown:

[0072] S201. When it is detected that the brightness target value in the target light type control instruction changes, start timing;

[0073] In the embodiment of the present invention, the target light type control instruction is scanned, and when it is detected that the brightness target value in the target light type control instruction changes, for example, jump from target brightness 1 to target brightness 2 or change from target brightness to 2 Jump to the target brightness 1, and start timing according to the counter, timer or other preferred timing methods.

[0074] S202, judging whether the timing time reaches a preset delay time;

[0075] In the embodiment of the present invention, the timing time is compared with a preset delay time, and it is judged whether the timing time reaches the preset delay time, wherein the preset dela...

Embodiment 3

[0082] In the embodiment of the present invention, when the target light type control command is a brightness down control command, according to the target light type control command, the flow of the method for determining the corresponding brightness adjustment step is as follows: image 3 shown, including steps:

[0083] S301. Obtain the brightness reduction time and time step contained in the target light pattern control instruction;

[0084] In the embodiment of the present invention, the brightness reduction time and time step corresponding to the brightness reduction control instruction in the target light type control instruction are acquired, wherein the time step is a fixed value set in advance based on experience.

[0085] S302. Determine the number of brightness reduction steps according to the brightness reduction time and the time step;

[0086] In the embodiment of the present invention, the brightness down-regulation time is divided by the time step to obtain t...

Abstract

The invention discloses a control method, a device and a system for lighting brightness. The control method comprises the following steps: when the position of an obstacle in front of a target vehicleis recognized to be moved, obstruction position information is obtained. A target light type control instruction is determine according to that obstacle position information, wherein, the target light type control instruction comprise an adjustment direction of brightness, a brightness target value, a corresponding adjustment time and a time step; Determining a corresponding brightness adjustmentstep size according to a target light type control command; The lighting brightness is controlled according to the corresponding brightness adjustment step length. The control method determines a target light type control command and a corresponding adjustment step length according to the obstacle position information when the position of the obstacle in front of the target vehicle is detected tomove, and controls the lighting brightness according to the corresponding brightness adjustment step length, so that the lighting brightness stairs are changed, and driving comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of automotive electronics, in particular to a method, device and system for controlling light brightness. Background technique [0002] The "far" and "bright" lighting of vehicle headlights at night provides drivers with a sufficient sense of safety, but if not reasonably controlled, it usually dazzles other road users and causes road hazards. [0003] With the development of technology, automotive lighting technology is also constantly improving, and intelligent anti-glare headlight technology has become a new lighting demand. The intelligent camera system identifies the position of obstacles and maps them to the light pattern, directly controls the change of the light pattern, and adjusts the brightness of the light according to the change of the light pattern. [0004] The inventor conducted research on the existing control process of light brightness and found that usually the position of the ob...
