Abstract

The invention relates to the field of automobile light control, and particularly discloses an automobile anti-dazzling rearview mirror control system and method, and the method comprises the steps that a collection module collects an illumination data set and stores the illumination data set into a data queue; a sorting module sorts the illumination data in the data queue from small to large according to the light intensity to obtain a light intensity sorting list; a screening module screens out two groups of illumination data groups in the middle of the data queue; a calculation module calculates an illumination average value of the screened illumination data set; and a processing module performs corresponding preset processing according to the illumination average value. Through the steps, the influence of transient strong and weak light on the judgment of the light intensity of the automatic anti-dazzling rearview mirror can be effectively avoided, so that the meaningless change ofthe reflectivity of the rearview mirror is avoided.

Description

technical field

[0001] The invention relates to the field of light control for vehicles, in particular to a control system and method for an anti-glare rearview mirror of a vehicle. Background technique

[0002] The anti-glare rearview mirror is composed of a special mirror, two photosensitive diodes and an electronic controller. The electronic controller receives the front light and rear light signals collected by the sensor and is installed under the front windshield of the car. The glare light intensity refers to the light intensity observed by the human eye after the rear car lights are reflected on the mirror surface of the anti-glare rearview mirror, which is collected by the glare sensor on the anti-glare rearview mirror control panel facing the rear .

[0003] It can be divided into manual anti-glare rearview mirror and automatic anti-glare rearview mirror. This patent is aimed at automatic anti-glare rearview mirror. The mirror has a constantly changing anti-glare...

Examples

Embodiment 1

[0039] Such as figure 1 As shown, in order to solve the problem that transient strong light or weak light will affect the control program and cause meaningless changes in the working state of the rearview mirror, the present invention proposes a control system for an automobile anti-glare rearview mirror, including:

[0040] The collection module is used to collect the illumination data group and store it in the data queue;

[0041] The sorting module is used to sort the lighting data in the data queue from small to large according to the light intensity, and obtain a light intensity sorting list;

[0042] A filtering module, used to filter out two groups of illumination data groups in the middle of the data queue;

[0043] A calculation module, configured to calculate the average illumination value of the filtered illumination data set;

[0044] The processing module is used for performing corresponding preset processing according to the light average value.

[0045] Where...

Embodiment 2

[0055] The present invention also provides a method for controlling an automobile anti-glare rearview mirror, which is characterized in that it comprises the steps of:

[0056] S1: collect the illumination data group and store it in the data queue;

[0057] S2: According to the light intensity, sort the illumination data in the data queue from small to large, and obtain the light intensity sorting list;

[0058] S3: Filter out two groups of illumination data groups in the middle of the data queue;

[0059] S4: Calculate the average illumination value of the filtered illumination data group;

[0060] S5: Perform corresponding preset processing according to the average value of light.

[0061] Further, in the step S1, the illumination data includes glare light data and ambient light data, and the data pair includes a first data queue and a second data queue, wherein:

[0062] The dazzle light data or the ambient light data is a lighting data group, the dazzle light data and the...
