[0002] For the same vehicle, the field of view seen through the front windshield in the main driver's seat is different due to the different heights and eye heights of the drivers. For example, for drivers with shorter heights, the field of view seen through the front windshield is very limited. The above problem is usually solved by adjusting the seat height, but if the seat is adjusted too high, it may cause the driver's leg extension to be restricted, affecting the comfort and safety of stepping on the accelerator and brake pedals, affecting the driving experience and bringing safety hazards. Therefore, how to enable drivers of different heights, especially those with shorter heights, to obtain the best field of view through the front windshield is a problem that needs to be solved.

[0017] The first-direction reflective module in the first reflective group below the second reflective group is used to obtain the reflected light of the second reflective group and reflect the light again based on the angle of the first-direction reflective module and the opening range of the light shielding layer;

[0018] At least one first reflective group and at least one second reflective group are used to repeat the above light reflection process, so that the light reflected by the last first reflective group enters the eyes of the driving object and forms the visual field of the driving object.

[0019] The vehicle front windshield vision automatic correction system provided by the embodiment of the present invention allows light to be reflected between multiple reflective modules in different directions by arranging the first reflective group and the second reflective group in sequence alternately, and the correction module has adjusted the multiple reflective modules according to the requirements of the standard visual field.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] Since drivers of different heights are in the main driving seat, there are differences in the fields of view seen through the front windshield. Especially for drivers of shorter heights, the field of view seen through the front windshield is very limited. If the seat height is adjusted, the driver's leg extension may be restricted, affecting the comfort and safety of stepping on the accelerator and brake pedals, and bringing safety hazards while affecting the driving experience. The vehicle front windshield vision automatic correction system provided by an embodiment of the present invention can automatically correct the driver's visual field of view through a correction module by determining the human eye height value when the human eye height value is within a preset range, without the need for manual seat adjustment, so that drivers of different heights can obtain the standard visual field of view that is most suitable for driving, thereby improving the driving experience of the driver and improving driving safety.

[0043] In this embodiment, a vehicle front windshield vision automatic correction system is provided. Figure 1is a schematic diagram of a vehicle front windshield vision automatic correction system according to an embodiment of the present invention, Figure 1 As shown, the system includes a camera, a front windshield and a correction module; the camera is arranged at the upper left of the main driving seat in the vehicle, and is used to collect image information of the driving object to determine the human eye height value of the driving object; the front windshield includes an outer layer of glass, multiple first-direction reflective modules, multiple second-direction reflective modules and an inner layer of glass, and is used to reflect light so that the driving object can obtain a visual field of the area in front of the vehicle; the correction module is used to adjust the multiple first-direction reflective modules and multiple second-direction reflective modules of the front windshield when the human eye height value of the driving object is within a preset range, so as to correct the visual field of the driving object to the standard visual field.

[0044] Specifically, Figure 2 is a schematic diagram of another vehicle front windshield vision automatic correction system according to an embodiment of the present invention, such as Figure 2 As shown, taking the perspective of the main driver's seat as an example, the camera is set at the upper left of the main driver's seat, and multiple reflective modules are arranged in the front windshield. It should be noted that Figure 2 This is only an example. In actual use, the reflective module cannot be directly seen from the outside or inside of the vehicle. The camera is any camera with an image processing function, and the embodiment of the present invention does not limit this. After the camera obtains the image information of the driving object, any existing image processing method can be used to determine the human eye height value. The front windshield forms a cavity between the outer glass and the inner glass, and there are multiple first-direction reflective modules and multiple second-direction reflective modules in the cavity. If the human eye height value is within a preset range, the driving object may be of low height. At this time, the visual field of the driving object is automatically corrected so that the visual field of the driving object is consistent with the standard visual field. The standard visual field is the visual field obtained by a driving object of normal height, which can be used as a reference standard for automatic correction. Optionally, the embodiment of the present invention does not limit the height of the driving object of normal height. The visual field of the driving object is automatically corrected by the correction module, without manual seat adjustment, so that driving objects of different heights can obtain the standard visual field that is most suitable for driving, improving the driving experience of the driving object and improving driving safety.

[0045] In some optional embodiments, any first-direction reflective module and any second-direction reflective module are both in the shape of long strips, connected to the fixing frame of the front windshield on both sides, and both include a mirror layer, a shading layer, a shading layer storage bin and a rotating shaft. The mirror layer of the first-direction reflective module faces the interior of the vehicle, and the mirror layer of the second-direction reflective module faces the exterior of the vehicle. The rotating shaft is used to control the opening range of the shading layer to adjust the range of the mirror layer for reflecting light.

[0046] Specifically, Figure 3is a schematic diagram of a reflective module according to an embodiment of the present invention. Figure 3 As shown, one side of any reflective module is a mirror layer, and the other side is a light-shielding layer, and a rotating shaft is installed on one side of the light-shielding layer. Figure 4 is a schematic diagram of another reflective module according to an embodiment of the present invention. Figure 4 As shown, any reflective module includes a mirror layer, a shading layer, a shading layer storage bin and a rotating shaft. When the shading layer is adjusted by the rotating shaft, for example, when the rotating shaft is controlled upward, the shading layer will slide upward and be stored in the shading layer storage bin. By controlling the rotating shaft to adjust the opening size of the shading layer, the range of the part of the mirror layer used to reflect light can be changed. When the shading layer is completely stored in the shading layer storage bin, the entire mirror layer can be used to reflect light. When half of the shading layer is opened and the remaining half is stored in the shading layer storage bin, half of the mirror layer can be used to reflect light. Multiple parts of the reflective module cooperate to form a visual field of the driving object.

[0047] In some optional embodiments, the correction module is also used to obtain the arrangement of at least one reflective module corresponding to the standard visual field of view and the placement angle of the reflective module and the opening range of the shading layer corresponding to each arrangement; the correction module is also used to divide multiple first-direction reflective modules and multiple second-direction reflective modules into at least one first reflective group and at least one second reflective group based on the arrangement of any reflective module; the correction module includes a motor control module, and the motor control module is used to adjust the arrangement position of at least one first reflective group and at least one second reflective group based on the arrangement of the reflective modules; the motor control module of the correction module is also used to adjust the angle of the first direction reflective module in at least one first reflective group and the opening range of the shading layer, and adjust the angle of the second direction reflective module in at least one second reflective group and the opening range of the shading layer based on the placement angle of the reflective module corresponding to the arrangement.

[0048] Specifically, the standard visual field can be achieved by arranging at least one reflective module, such as alternating first-direction reflective modules and second-direction reflective modules, arranging multiple second-direction reflective modules first and then arranging multiple first-direction reflective modules, etc. Figure 5 Schematic diagram of arrangement of reflective modules according to an embodiment of the present invention. Figure 5 As shown, there are three possible arrangements of the first direction reflective modules and the second direction reflective modules, such as being in the same plane, being staggered, and having overlapping parts. Optionally, there are other arrangements, such as arranging the two reflective modules alternately at a certain distance, arranging a plurality of second direction reflective modules first and then arranging a plurality of first direction reflective modules, etc. Figure 5The above is only an example and is not intended to be limiting. Taking alternating arrangement as an example, there are multiple arrangements, such as two first-direction reflective modules arranged after two second-direction reflective modules, and continue to be arranged alternately according to the above arrangement, or two first-direction reflective modules arranged after three second-direction reflective modules, and continue to be arranged alternately according to the above arrangement, etc. The correction module can be grouped according to the arrangement of any reflective module, such as the alternating arrangement of two first-direction reflective modules arranged after the above two second-direction reflective modules. The correction module can be divided into multiple first reflective groups and multiple second reflective groups, each of which includes two first-direction reflective modules, and each of which includes two second-direction reflective modules. After the correction module is grouped, the reflective modules in the multiple first reflective groups and the multiple second reflective groups are adjusted by the motor control module according to the placement angle of the reflective modules corresponding to the standard visual field. It should be noted that the arrangement and placement angle of the reflective modules corresponding to the standard visual field can be obtained by pre-training, and the training process can be implemented by existing technology, which will not be repeated here. For ease of description, the embodiment of the present invention is divided into three first reflective groups and three second reflective groups. Figure 5 The second situation shown is arranged alternately in sequence, each first reflective group includes two first-direction reflective modules, each second reflective group includes two second-direction reflective modules, each reflective module has an angle of 10° with the central axis, and the light shielding layer is half opened as an example. The above situation is one of the situations in which a standard visual field can be formed. According to the arrangement corresponding to the standard visual field, the placement angle of the reflective module and the opening range of the light shielding layer, the corresponding position, angle and light shielding layer of the reflective module are adjusted to prepare for forming a standard visual field.

[0049] In some optional embodiments, when at least one first reflective group and at least one second reflective group are arranged alternately in sequence, the second direction reflective module in the second reflective group located in the front windshield is used to obtain light emitted by any object in the front area of ​​the vehicle after being reflected by the outer glass, and reflects the light based on the angle of the second direction reflective module; the first direction reflective module in the first reflective group located below the second reflective group is used to obtain the reflected light of the second reflective group, and reflects the light again based on the angle of the first direction reflective module; at least one first reflective group and at least one second reflective group are used to repeat the above light reflection process, so that the light reflected by the last first reflective group enters the eyes of the driving object, forming the visual field of the driving object.

[0050] Specifically, assuming that multiple reflective modules are arranged according to Figure 5 The second case shown in is arranged alternately, Figure 6is a schematic diagram of forming a visual field of a driving object according to an embodiment of the present invention, such as Figure 6 As shown, according to the above adjustment of multiple reflective modules, the light emitted by any object reaches the two second-direction reflective modules in the second reflective group after being reflected by the outer glass, and the light is reflected according to the placement angle of the two second-direction reflective modules and the opening range of the shading layer, and reaches the first reflective group located below the second reflective group. After the two first-direction reflective modules in the first reflective group obtain the reflected light, the light is reflected again according to the placement angle of the first-direction reflective module and the opening range of the shading layer. The above light reflection process is repeated until the first reflective group located at the bottom reflects the light into the eyes of the driving object, and the visual field obtained by the driving object is consistent with the standard visual field. It should be noted that although it is assumed that three first reflective groups and three second reflective groups are arranged in the front windshield, the light emitted by the object in the front area of ​​the vehicle may reach any one of the three second reflective groups. Regardless of the second reflective group at any position where the light emitted by the object reaches, the light will continue to be reflected according to the arrangement of the reflective groups until the last first reflective group reflects the light into the human eye. By arranging the first reflective group and the second reflective group alternately in sequence, the light is reflected between reflective modules in different directions, and the correction module has adjusted the multiple reflective modules according to the requirements of the standard visual field. Therefore, after the light enters the eyes of the driving subject, a visual field consistent with the standard visual field is formed, which improves the driving experience of the driving subject and improves driving safety.

[0051] In some optional embodiments, Figure 7 is a schematic diagram of correcting the visual field according to an embodiment of the present invention, such as Figure 7 As shown, the visual fields corresponding to different human eye positions are different. The vehicle front windshield automatic vision correction system adopted in the embodiment of the present invention can automatically perform correction without changing the height of the human eye position, so that the corrected visual field is consistent with the standard visual field, thereby improving the driving experience of the driving subject and improving driving safety.

[0052] In some optional embodiments, when there is a field of view intersection area in any first reflective group and / or any second reflective group, the correction module is also used to control the rotation axis of the first direction reflective module in the first reflective group and / or the rotation axis of the second direction reflective module in the second reflective group, and adjust the opening range of the shading layer of the first direction reflective module and / or the opening range of the shading layer of the second direction reflective module.

[0053] Specifically, since each first reflective group and each second reflective group includes at least one reflective module, if there are two or more reflective modules, a cross-viewing area may appear. Figure 8 is a schematic diagram of a visual field intersection area according to an embodiment of the present invention. Figure 8 As shown, it is assumed that the two boundaries of the second direction reflective module A are at positions 1 and 3 on the virtual imaging layer, that is, the visual field formed by the second direction reflective module A is an area between 1 and 3. The two boundaries of the second direction reflective module B are at positions 2 and 4 on the virtual imaging layer, that is, the visual field formed by the second direction reflective module B is an area between 2 and 4. Figure 8 As shown, there is an overlap between the area 2 and 3, that is, the field of vision intersection area. For the above situation, the correction module can control the rotation axis, and can adjust the shading layer of the second direction reflective module A through the rotation axis, so that the visual field corresponding to the second direction reflective module A is the area between 1 and 2, and at this time, there is no overlap between the visual fields corresponding to the second direction reflective module A and the second direction reflective module B. Alternatively, the shading layer of the second direction reflective module B can be adjusted through the rotation axis, so that the visual field corresponding to the second direction reflective module B is the area between 3 and 4, and there is no field of vision intersection area. By adjusting the field of vision intersection area, glare and ghosting can be avoided after the light reflected by the reflective module enters the human eye, thereby improving the driving safety of the driver.

[0054] In some optional embodiments, the system also includes terminal application software, which exchanges information with the correction module through the wireless communication module of the terminal; the correction module is also used to collect working information of the front windshield, and the working information includes the visual field obtained by the front windshield for the driving object, the working information of multiple first-direction reflective modules, and the working information of multiple second-direction reflective modules; the correction module is also used to send the working information of the front windshield to the terminal application software; the terminal application software is used to receive and display the working information of the front windshield.

[0055] Specifically, the terminal application software is installed on a terminal bound to the vehicle, such as a mobile phone of the driving subject, an operating terminal in the vehicle, etc. The correction module collects various working information, such as the visual field obtained for the driving subject, the working time of each reflective module, the opening range of the shading layer, the placement angle and arrangement, etc. After the correction module collects the working information, it sends it to the mobile phone of the driving subject or the operating terminal in the vehicle, and the driving subject can monitor the working condition of the front windshield in real time. Through the information interaction between the correction module and the terminal application software, the working condition and visual field of the reflective module can be viewed through the terminal application software, realizing remote monitoring of the reflective module, and improving the intelligence of the system.

[0056] In an optional embodiment, the terminal application software is also used to send visual field correction instructions to the correction module; the correction module is also used to receive the visual field correction instructions, and adjust multiple first-direction reflective modules and multiple second-direction reflective modules of the front windshield based on the visual field correction instructions.

[0057] Specifically, the visual field correction instruction can be for opening, closing, adjusting the opening range of the shading layer, adjusting the placement angle, adjusting the arrangement position, etc. of any reflective module. If the driver needs to drive the vehicle, the correction module has automatically corrected after confirming the eye height value of the driver. At this time, if the driver wants to make adjustments, the visual field correction instruction can be sent to the correction module through the terminal application of the driver's mobile phone or the operating terminal in the car, so that the correction module makes corresponding adjustments to the reflective module. For example, the visual field correction instruction is to adjust the opening range of the shading layer of all reflective modules to half of all openings. After the correction module receives the visual field correction instruction, it controls the rotation axis of each reflective module to open half of the shading layer of each reflective module. By sending the visual field correction instruction through the terminal application software, the reflective module can be adjusted accordingly, and the remote control of the reflective module can be realized, which improves the intelligence of the system, and at the same time, the visual field can be adjusted in a personalized manner to improve the driving experience of the driver.

[0058] In an optional embodiment, the correction module is also used to control the rotation axes of multiple first-direction reflective modules and the rotation axes of multiple second-direction reflective modules, and adjust the shading layers of multiple first-direction reflective modules and the shading layers of multiple second-direction reflective modules when the camera does not capture image information of the driving object, so that the range of the mirror layers of the multiple first-direction reflective modules and the multiple second-direction reflective modules used to reflect light is zero.

[0059] Specifically, when the camera does not collect image information of the driving object, that is, it is an unmanned vehicle and the vehicle may be parked, the correction module can adjust the shading layer by controlling the rotating axis so that the mirror layer of the reflective module cannot reflect light, that is, the mirror layer is completely covered by the shading layer, which can prevent direct sunlight from causing the temperature inside the car to rise, protect the electronic equipment in the car from damage by high temperature, and improve the comfort of passengers when there are still passengers in the car.

[0060] The vehicle front windshield vision automatic correction system provided by the embodiment of the present invention collects image information of the driving object through a camera and determines the human eye height value. When the human eye height value is within a preset range, the visual field of the driving object can be automatically corrected through a correction module without manual seat adjustment, so that driving objects of different heights can obtain the standard visual field that is most suitable for driving, thereby improving the driving experience of the driving object and improving driving safety.

[0061] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
