Embodiment 1

[0041] Reference figure 1 , The high beam prevention method of the present invention includes the following steps:

[0042] Step S101: Collect the light incident on the cab, and determine the light intensity of the light.

[0043] Step S102: Calculate the difference between the light intensity and the ambient light intensity, where the ambient light intensity is the light intensity collected at the last moment, and the light intensity variation range is determined according to the ambient light intensity.

[0044] Step S103: Determine whether the difference value is within the range of the light intensity variation.

[0045] Step S104: If not, switch the state of the light shield to change the intensity of light incident on the cab.

[0046] The method for preventing high beams further includes: setting different ranges of the ambient light intensity variation range according to the initial light intensity of the current environment, wherein the ambient light intensity variation range i...

Abstract

The invention relates to the technical field of vehicle-mounted equipment, and provides a high beam prevention method and system and terminal equipment, and the method comprises: collecting light entering a cab, and determining the light intensity of the light; calculating a difference value between the light intensity and the current ambient light intensity, determining a light intensity variation range according to the ambient light intensity, and judging whether the difference value is within the light intensity variation range of the environment or not; and if not, the state of the shadingplate is switched to change the intensity of light entering the cab. Opening and closing of the shading plate are controlled in a dynamic threshold value mode. Compared with a fixed threshold value method, the high beam prevention method is advantageous in that the problem that a shading system is opened under unnecessary conditions can be effectively avoided, wrong influences on a driver are prevented, meanwhile, and, due to the fact that the opening time of the shading system is shortened, electric energy is effectively saved.

Description

Technical field [0001] The present invention relates to the technical field of vehicle equipment, in particular to a method, system and terminal equipment for preventing high beams. Background technique [0002] Research on anti-glare technology abroad has a history of more than half a century; domestically, it has been engaged in the development of similar technologies for more than 20 years. Among the many research technologies, there are several realistic and mature technical concepts as follows: use the wave of light to add polarizers to vehicles, but this method is too targeted and the actual use effect is not ideal. Using polarization technology, it is necessary to install polarizers on the vehicle's high beam and windshield, which can only solve the glare problem of the night meeting. However, it has no ideal effect on the reflective glare of traffic during the day and the glare of obliquely approaching vehicles at night. Some people have proposed that the use of infrare...
