Background art:
with the continuous development of automobiles, more and more automobiles abandon radios with single functions and crude appearances, and adopt central control large screens with more powerful functions and more diversified shapes. And with the continuous upgrading and updating of automobile models, the arrangement form of the central control large screen is various and the size of the central control large screen is larger and larger. The central control large screen is used as an automobile internal light source, and virtual images can be generated on a front windshield and a side windshield to influence the safe driving visual field. The invention introduces a method for checking the influence of a central control screen light source on a safe driving visual field, which can help a vehicle enterprise to quickly and effectively avoid the design defect in a design stage.

the invention provides a method for checking the influence of a central control screen light source on a safe driving visual field, which aims to solve the problems in the prior art.
The technical scheme adopted by the invention is as follows: a method for checking the influence of a central control screen light source on a safe driving visual field comprises the following specific steps:
the method comprises the following steps: designing input parameters, namely checking conditions, including the inner surface of the front windshield glass, a regulation front view B area, a central control large screen light emitting surface and an eye ellipse;
step two: translating the reflection translation line, wherein the closer the reflection translation line is to the upper boundary of the front view B area of the rule, the closer the reflection light line is to the eye ellipse, so that no reflection light enters the eye ellipse when the reflection translation line is at the upper boundary of the front view B area of the rule, namely, the incidence point can not generate a virtual image in the B area;
step three: and translating the incident point on the central control large screen, selecting the points at the upper limit position and the lower limit position of the central control large screen, and enabling no reflected light to enter an eye ellipse, namely representing that the central control large screen cannot generate a ghost in a front windshield view rule area, so that the design requirement is met.
The invention has the following beneficial effects: the method for checking whether the central control large screen generates the virtual image in the front windshield glass regulation visual field area can be quickly and effectively applied to the early design of the automobile, and the phenomenon that the light source in the automobile images on the front windshield to influence the driving safety is avoided.

FIG. 1 is a schematic diagram of design input parameters.
Fig. 2 is a schematic view of a translational reflection translation line.
FIG. 3 is a schematic diagram of translating an incident light source point.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The invention discloses a method for checking the influence of a control screen light source on a safe driving visual field, which comprises the following specific steps:
the method comprises the following steps: designing input parameters, namely checking conditions, including the inner surface of the front windshield glass, a regulation front view B area, a central control large screen light emitting surface and an eye ellipse;
step two: the reflection translation line is closer to the upper boundary of the B area, and the reflection light line is closer to the eye ellipse, so that no reflection light enters the eye ellipse when the reflection translation line is at the upper boundary of the B area, namely, the incidence point can not generate a virtual image in the B area;
step three: by translating the incident point on the central control large screen, the point at the upper limit position and the lower limit position of the central control large screen is selected, no reflected light enters the eye ellipse, namely, the central control large screen does not generate ghost in the front windshield view rule area, and the design requirement is met.
According to the method for checking the influence of the screen control light source on the safe driving visual field, the reflection rays of all incidence points on the central control large screen on the B area are proved not to enter the eye ellipse, namely, the central control large screen does not generate a ghost in a front windshield visual field regulation area.
According to the method for checking the influence of the screen control light source on the safe driving vision, the inner surface of the front windshield glass, the front vision B area surface, the light emitting surface of the large central control screen and the eye ellipse of the designed vehicle type are introduced, so that the reflected light of the large central control screen on the front windshield of the designed vehicle type can be quickly generated, and the checking is finished.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
