Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a control method of a sun visor according to an embodiment of the present invention, and referring to fig. 1, the control method of the sun visor includes step S110: acquiring an optical signal of a specific area on the vehicle glass, wherein the specific area is a sight line area formed on the vehicle glass when a user looks flat; and step S120: when the optical signal of the specific area meets a first preset condition, the light transmittance of the sun shield is adjusted to be a preset light transmittance.
In step S110, the specific area may be a sight line area formed on the vehicle glass by the user sitting on the vehicle seat. In some examples, the position of the vehicle seat is not particularly limited, and may be, for example, a driver seat or a passenger seat of the vehicle, or may be another vehicle seat at any position in the rear row, and accordingly, the vehicle glass may be a front windshield glass, or may be a side window glass or a rear windshield glass. In other examples, the particular area may be a corresponding line of sight area on the front windshield when the user is seated in the vehicle seat. Therefore, the influence of the optical signal on the eyes and the sight of the user can be effectively judged by acquiring the optical signal of the specific area on the glass.
In step S110, the specific area may be a sight line area formed on the vehicle glass when the user sits on the vehicle seat and the user' S eyes look up the vehicle glass. In some examples, the sight line region may be a region outside the eye gaze angle of the user when looking forward at his eyes, for example, may be a region above the gaze angle, wherein the sight line region formed by head-up includes the gaze angle (region). In other examples, the gaze area may be an area 0 to 45 degrees above the gaze angle of the user when the user looks at the front, i.e. an area 0 to 45 degrees above the gaze angle, preferably an area 5 to 30 degrees above the gaze angle. In general, when a user drives a vehicle while sitting on a driver's seat and looks ahead with his eyes, a certain gaze angle (region) is usually formed on the front windshield, and therefore, by defining the specific region as a region other than the gaze angle, it is possible to ensure that the line of sight of the user when driving the vehicle is not affected during movement of the sun visor or change of the light transmittance, thereby improving the driving safety; furthermore, the specific area is specified to be an area which is larger than the specific degree of the watching angle, so that the change of light transmittance and the like in the area can be ensured, the driving safety is not influenced, meanwhile, the external light signal can be effectively shielded, the interference or damage of the external light signal to the eyes of the user can be prevented, and the driving safety and the use reliability of the user can be further improved.
In step S110, the optical signal may be acquired by an optical sensor on the glass. In some examples, the light sensor may be designed to match with the height of the user, for example, the light sensor may be movable, the user may manually adjust the height of the light sensor, and the light sensor may also be controlled to automatically move by other control devices to match with the height of the user, so as to further identify the head-up area, the gaze angle, etc. of the user, thereby more accurately implementing the adjustment of the light signal of a specific area.
In step S120, when the acquired optical signal of the specific area satisfies a first preset condition, the light transmittance of the sun visor is adjusted to a preset light transmittance. From this, light can more reflect light to user's influence degree through the light signal of specific area, and the luminousness to the sunshading board that can be better is adjusted, improves the degree of accuracy of adjusting the luminousness to obtain the light signal of specific area on the glass, can not receive the influence of sunshading board, no matter the sunshading board is packed up or is put down and all can be obtained. That is, this embodiment's technical scheme has solved and has adjusted the luminousness of sunshading board according to the light signal on the sunshading board, can't adjust when not putting down the sunshading board, adjusts the lower problem of the degree of accuracy of luminousness moreover, has reached the luminousness of automatically regulated sunshading board to improve the effect of the degree of accuracy of adjusting the luminousness.
In step S120, the manner of adjusting the light transmittance of the sun visor is not particularly limited. In some examples, the sun visor may include a photochromic layer or an electrochromic layer, or other color-changing layers capable of changing light transmittance according to light signals, so that the light transmittance of the color-changing layer of the sun visor may be directly adjusted according to the light signals, i.e., the adjustment of the light transmittance of the sun visor is realized.
In other examples, the electrical signal of the electrochromic layer of the sun visor may be adjusted according to the light signal of the specific area, for example, a voltage signal of the electrochromic layer of the sun visor may be adjusted, a current signal of the electrochromic layer of the sun visor may also be adjusted, and other electrical signals of the sun visor may also be adjusted, so that the light transmittance of the electrochromic layer may be adjusted by adjusting the electrical signal of the electrochromic layer of the sun visor, that is, the adjustment of the light transmittance of the sun visor is achieved.
In step S120, the sun visor may be a fixed position or size sun visor or a variable position or size sun visor. In some examples, the position or size of the visor may be manually adjustable by a user, or may be set to be automatically adjustable. In other examples, the visor may be a sliding visor, a roller visor, or other type of position or size adjustable visor. Therefore, the specific form of the sun shield and the adjusting mode of the sun shield can be flexibly set according to different application scenes, so that the application scenes can be matched, and the applicability and the use flexibility of the sun shield are improved.
In step S120, the specific case where the optical signal of the specific region satisfies the first preset condition is not particularly limited. In some examples, the light signal of the specific area may be a light intensity of the specific area, and accordingly, the first preset condition may be a first preset light intensity. In other examples, the light signal of the specific area may be a ratio of an ambient light intensity and a light intensity of the specific area, and accordingly, the first preset condition may be a first preset ratio. From this, can adjust the luminousness of sunshading board through the different light signal that acquire specific area to promote the suitability of sunshading board.
Fig. 2 is a flowchart of a control method of a sun visor according to another embodiment of the present invention, and on the basis of the above embodiment, optionally, referring to fig. 2, the control method of the sun visor may include step S210: acquiring an optical signal of a specific area on the glass of the vehicle, wherein the specific area is a sight line area formed on the glass when a user looks flat; step S220: determining the light intensity of the specific area according to the optical signal of the specific area; and step S230: when the light intensity of the specific area meets the first preset light intensity, the light transmittance of the sun shield is adjusted to the preset light transmittance.
In step S210, the light intensity of the specific area may be determined according to the light signal of the specific area, and the degree of influence of the external light on the user may be better analyzed through the light intensity of the specific area.
In step S220, the light intensity of the specific region may be directly determined according to the light signal of the specific region, or may be converted into the light intensity through another light signal.
In step S230, when the light intensity of the specific region satisfies a first preset light intensity, the light transmittance of the sun visor is adjusted to the preset light transmittance, where the specific value of the first preset light intensity is not particularly limited, for example, the first preset light intensity may be more than one value, and correspondingly, the preset light transmittance may also be more than one value. Typically, the light intensity in a particular area is less than X1When the light intensity of a specific area is larger than X, the human eyes feel comfortable1At that time, the human eye begins to become distracting to receive light once the light intensity in a particular area reaches X2The eye is caused byThe received light is too intense and begins to completely filter out the light, and prolonged exposure to such intense light can cause damage, resulting in temporary or even permanent blindness. Therefore, the first preset light intensity and the preset light transmittance corresponding to the first preset light intensity can be adaptively set according to the receiving degree of the light by the eyes of the user, so that the influence of the light signal on the user is reduced, the user can drive a vehicle better, and the condition that the sight of the user is influenced to cause traffic accidents is avoided.
In some examples, the first preset light intensity may be less than X1Accordingly, the preset transmittance of the sun visor may be the maximum transmittance Y1Therefore, the external light rays can not be shielded, and the sight of the user is prevented from being interfered; in other examples, the first predetermined light intensity may be greater than X1And is less than X2Accordingly, the preset light transmittance of the sun visor may be the medium light transmittance Y2Therefore, the light transmittance of a certain degree can be reserved while the eyes of the user are protected, so that the sight of the user is not completely shielded, the driving safety of the user is improved, and the like; in still other examples, the first predetermined light intensity may be greater than X2Accordingly, the preset transmittance of the sun visor may be the minimum transmittance Y3Thereby, the light intensity of a particular region may be substantially completely blocked to prevent damage to the user's eyes by the light intensity. Here, the specific values of the first preset light intensity and the preset light transmittance, and the number of the value intervals may be determined according to an actual situation, which is not limited herein. Therefore, the use matching performance of the sun visor can be improved, and the experience comfort of a user using the sun visor is improved.
Fig. 3 is a flowchart of a control method of a sun visor according to another embodiment of the present invention, and on the basis of the above embodiment, optionally, referring to fig. 3, the control method of the sun visor includes step S310: acquiring an optical signal of a specific area on the vehicle glass, wherein the specific area is a sight line area formed on the vehicle glass when a user looks flat; step S320: acquiring an ambient light signal, and determining the intensity of ambient light according to the ambient light signal; step S330: determining the light intensity of the specific area according to the optical signal of the specific area; and step S340: when the ratio of the ambient light intensity to the light intensity of the specific area meets a first preset ratio, the light transmittance of the sun shield is adjusted to be preset.
In step S320, the ambient light signal may refer to a light signal of an environment in which the entire vehicle body of the vehicle is located, for example, a plurality of light sensors may be regularly arranged on the vehicle body, and light signals detected by the plurality of light sensors are averaged to obtain the ambient light signal. In some examples, the ambient light intensity is determined from the acquired ambient light signal, from which the light intensity of the environment in which the vehicle is located can be known.
Specifically, when the external ambient light intensities are different, the acceptable or comfortable light brightness corresponding to human eyes may be different, and therefore, the adjustment of the light transmittance of the sun visor can be more accurately realized according to the ratio of the ambient light intensity to the light intensity of the specific area.
Likewise, the specific value of the first predetermined ratio is not particularly limited, for example, the first predetermined ratio may be more than one value, and accordingly, the predetermined transmittance may also be more than one value. For example, when the first preset ratio is smaller, the preset light transmittance of the sun shield is adjusted to be larger; when the first preset ratio is larger, the preset light transmittance of the sun shield is smaller through adjustment, so that the stimulation to the eyes of a user is reduced. The first preset ratio can also be divided into multiple gears, each gear corresponds to a corresponding preset light transmittance, and the corresponding light transmittance can be selected according to the gear in which the ratio is located. In some examples, a first determination table may be constructed to correspond the ratio of different ambient light intensities and the light intensity of a specific region to different transmittances, so that when adjustment of the transmittances is performed, adjustment can be directly performed through the table.
Typically, the ratio of the intensity of the ambient light to the intensity of the light in the specific area is less than Z1The human eye feels comfortable when the ratio of the ambient light intensity to the light intensity of a specific area is greater than Z1At that time, the human eye begins to become distracting to receive light once the ratio of the ambient light intensity to the light intensity in a particular area reaches Z2When the eye is open due to too strong light receivedComplete light rejection occurs, and prolonged exposure to such intense light can cause damage, resulting in temporary or even permanent blindness. Therefore, the first preset ratio and the preset light transmittance corresponding to the first preset ratio can be adaptively set according to the receiving degree of the eyes of the user to the light, so that the influence of the light signal on the user is reduced, the user can drive a vehicle better, and the condition that the sight of the user is influenced to cause traffic accidents is avoided.
In some examples, the first preset ratio may be less than Z1Accordingly, the preset transmittance of the sun visor may be the maximum transmittance Y1Therefore, the external light rays can not be shielded, and the sight of the user is prevented from being interfered; in other examples, the first predetermined ratio may be greater than Z1And is less than Z2Accordingly, the preset light transmittance of the sun visor may be the medium light transmittance Y2Therefore, the light transmittance of a certain degree can be reserved while the eyes of the user are protected, so that the sight of the user is not completely shielded, the driving safety of the user is improved, and the like; in still other examples, the first predetermined ratio may be greater than Z2Accordingly, the preset transmittance of the sun visor may be the minimum transmittance Y3Thereby, the light intensity of a particular region may be substantially completely blocked to prevent damage to the user's eyes by the light intensity. Here, the specific values of the first preset ratio and the preset light transmittance, and the number of the value intervals may be determined according to actual conditions, and are not limited herein. Therefore, the use matching performance of the sun visor can be improved, and the experience comfort of a user using the sun visor is improved.
On the basis of the above embodiment, fig. 4 is a flowchart of a control method of a sun visor according to another embodiment of the present invention, and optionally, referring to fig. 4, the control method of the sun visor includes step S410: acquiring an optical signal of a specific area on the vehicle glass, wherein the specific area is a sight line area formed on the vehicle glass when a user looks flat; step S420: when the maintaining time of the optical signal in the specific area meeting the first preset condition is longer than the first preset time, the light transmittance of the sun shield is adjusted to be the preset light transmittance.
In step S420, the size of the first preset time is not particularly limited, and different preset time values may be set according to different application scenarios. In some examples, the first preset time may be, for example, 2s, 3s, 4s, or 5s, etc. In other examples, the first preset time may also be 10s, 20s, 30s, 60s, or the like, for example. Under the condition, when the maintaining time that the optical signal of the specific area meets the first preset condition is longer than the first preset time, the light transmittance of the sun shield is adjusted to avoid misjudgment, and the temporary (for example, 1s) strong or weak illumination condition can be filtered out, so that the condition that the adjustment and control are too frequent and the use comfort is influenced is prevented.
