The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0042] Please see Figure 1 This is a schematic flowchart of a vehicle sunshade control method provided in an embodiment of this application, which may specifically include:

[0043] S110, Obtain ambient brightness information;

[0044] For example, to achieve the above functions, the vehicle heat insulation and sunshade system includes: a controller, a light sensor, a windshield, a left front window, a left rear window, a left rear corner window, a right front window, a right rear window, a right rear corner window, and a rear windshield; a solar cell, a backup battery, and a vehicle controller; the solar cell is used to collect solar energy and charge the backup battery; the backup battery provides power to the heat insulation and sunshade system; as... Figure 2 As shown, dimming films are installed on the front windshield, left front side window, left rear side window, left rear corner window, right front side window, right rear side window, right rear corner window, and rear windshield. Figure 3 As shown, the front windshield, left front side window, left rear side window, right front side window, and right rear side window are divided into upper and lower areas, namely areas A and B, and areas C and D; the left rear side window, right rear corner window, and rear windshield are designated as area E, and the dimming film controls each area separately. Ambient brightness information is acquired through a light sensor in the heat insulation and sunshade system, and the acquired ambient brightness information is transmitted to the controller. The controller adjusts the light transmittance of the glass in the non-transmitted areas according to a predetermined control strategy. It should be noted that this application uses electrochromic glass, and the light transmittance is changed by controlling the current and voltage of the electrochromic glass; the specific principle is not elaborated here.

[0045] S120. Control the first light transmittance of the road condition observation area glass based on the above-mentioned ambient brightness information, wherein the above-mentioned road condition observation area glass is the glass corresponding to the area below the preset height of the windshield and the movable window glass.

[0046] For example, based on the ambient brightness information obtained from the light sensor, the light transmittance of the glass in the road condition observation area is controlled to a first light transmittance. The road condition observation area is as follows: Figure 3 The areas A and C shown correspond to the glass sections in the windshield and power windows that are below the preset height.

[0047] S130. Based on the above-mentioned ambient brightness information, control the second light transmittance of the glass in the non-road condition observation area, wherein the glass in the non-road condition observation area refers to the glass in the area below the preset height of the windshield and the movable window glass, the fixed window glass and the rear windshield glass, and the second light transmittance is less than or equal to the first light transmittance.

[0048] For example, based on the ambient brightness information obtained by the light sensor, the light transmittance of the glass in the non-road condition observation area is controlled to be a second light transmittance. The glass in the non-road condition observation area is as follows: Figure 3 Zones B, D, and E, as shown, correspond to the areas of the windshield and movable windows below a preset height, as well as the fixed windows and rear windshield. The second light transmittance is less than or equal to the first light transmittance. When the vehicle is unoccupied and stationary, the first and second light transmittances can be set to be equal to avoid overheating the vehicle. Alternatively, when the surrounding environment is dim, the first and second light transmittances can be set to be equal to ensure sufficient interior lighting. While the vehicle is in motion and in bright light, the first light transmittance is controlled to be greater than the second light transmittance, ensuring clear road condition information for the user through the road observation area, while the non-road observation area uses a lower light transmittance to block strong light.

[0049] In summary, the vehicle sunshade control method provided in this application obtains the ambient brightness information of the vehicle, uses electrochromic glass, and employs zoned control of the light transmittance of the windshield and windows to achieve the function of an electronic sunshade. Moreover, it can control the light transmittance of different areas according to the parking and driving states, thereby meeting the light transmittance requirements for observing the outside view while driving and achieving the effect of heat insulation and sunshade, thus improving the comfort of vehicle use and enhancing the vehicle's intelligence and technological feel.

[0050] In some examples, the above method also includes:

[0051] Obtain vehicle seat height information;

[0052] Obtain driver's height information;

[0053] The preset height is determined based on the seat height information and the driver's height information.

[0054] For example, the solution proposed in this application is to control the windows and windshield in zones by setting a preset height. For different users, the appropriate preset height can be determined based on the height of the vehicle seat and the driver's height information, thereby maximizing the sunshade effect without affecting the user's normal driving behavior.

[0055] If the driver's height information cannot be obtained, it can also be obtained through methods such as... Figure 4 The preset height is determined by the following formula:

[0056] H = H1 + 638 (mm)

[0057] In the formula,

[0058] H is the preset height value of the upper and lower partition lines of the glass;

[0059] H1 is the height value of the seat design reference point R;

[0060] 638mm is an empirical value that satisfies the observation line of most drivers.

[0061] In summary, the vehicle sunshade control method provided in this application adjusts the preset height value according to different users, thereby specifying the most suitable control scheme for different users.

[0062] In some examples, the first light transmittance of the glass in the road condition observation area is controlled based on the aforementioned ambient brightness information; the second light transmittance of the glass in the non-road condition observation area is controlled based on the aforementioned ambient brightness information, including:

[0063] When the ambient brightness information is higher than the preset brightness, the first transmittance is determined according to the preset relationship between the ambient brightness information and the light transmittance.

[0064] The second light transmittance of the glass in the non-road condition observation area is controlled according to the first light transmittance and the preset proportional coefficient, wherein the preset proportional coefficient is less than 1.

[0065] For example, if the ambient brightness is higher than the preset brightness while the vehicle is in motion, sunshade control is required. First, the first transmittance is determined based on the ambient brightness information and the preset relationship between light transmittance. Figure 5 The table shown is used to determine the first transmittance, and a proportionality coefficient less than 1 is used to generate the second transmittance, ensuring that the second transmittance is less than the first transmittance.

[0066] Specifically, the following steps can be taken:

[0067] Step S210: The controller receives information from the vehicle controller, including vehicle speed information V≥0 (km / h), door lock information door lock signal off, seat pressure signal, G≥G1 (G1 is a set value, G1∈(30N, 60N)). It is determined that the vehicle is in a driving state (there is someone in the vehicle, then enter the driving heat insulation and sunshade control;

[0068] Step S220: When the ambient light intensity information LS≥L1 (L1 is a preset light intensity, L1∈(1600Lus, 2000Lus)) and the duration t≥t1 (t1 is a set value, t1∈(2s, 6s)), the controller determines it is daytime and activates the vehicle heat insulation and sunshade system. The controller controls the control system to make all the glass in area A and area C reach the set light transmittance LT = LT1 (LT1 is a set value, LT1∈(50%, 60%)), and make the glass in area B, area D, and area E reach the light transmittance LT = LT2 (LT2 is a set value, LT2∈(10%, 50%)), so that area B achieves the function of an electronic sunshade.

[0069] In summary, the vehicle sunshade control method provided by the embodiment of the present application constructs a preset relationship of light transmittance, determines the first light transmittance by looking up a table, and generates the second light transmittance using a scale factor less than 1, thereby controlling the difference in light transmittance of different glass areas, and providing an electronic sunshade effect for the driver on the basis of ensuring that the driver can observe the field of vision carefully and well.

[0070] In some examples, controlling the first light transmittance of the glass in the road condition observation area based on the above ambient light intensity information and controlling the second light transmittance of the glass in the non-road condition observation area based on the above ambient light intensity information includes:

[0071] When the above ambient light intensity information is lower than the preset light intensity, control the first light transmittance and the second light transmittance to the maximum light transmittance.

[0072] Exemplarily, if the preset signal value of the light sensor LS < L1 (L1 is a preset light intensity, L1∈(1600Lus, 2000Lus)) and the duration t≥t1 (t1 is a set value, t1∈(2s, 6s)), the controller determines it is night and turns off the vehicle heat insulation and sunshade system; improve the safety of the people in the vehicle observing the outside field of vision; the vehicle glass returns to the set maximum light transmittance LT = LT3, (LT3 is a set value, LT3∈(80%, 95%)

[0073] In summary, the vehicle sunshade control method provided by the embodiment of the present application ensures that all glass areas have the maximum light transmittance when the ambient light intensity is less than the preset light intensity, ensures the interior light of the vehicle, and ensures the safety of vehicle driving.

[0074] In some examples, the above method further includes:

[0075] Obtain the load information of the seat;

[0076] When all the above load information is less than the preset load and the above ambient brightness information is higher than the preset brightness, the above first light transmittance and the above second light transmittance are the minimum light transmittances.

[0077] Exemplarily, when the load information cloud is less than the preset load, the vehicle is in an unmanned state. If the ambient brightness is higher than the preset brightness, ensure that all vehicle windows have the minimum light transmittance for heat insulation. At the same time, if the ambient brightness is lower than the preset brightness, ensure that the vehicle windows have the maximum light transmittance to increase the interior temperature and ensure the interior brightness.

[0078] Specifically, it can be controlled through the following steps: <所

[0079] Step S310: The controller receives information from the vehicle controller, including vehicle speed information V = 0 (km / h), door lock information door lock signal off, seat pressure signal, G < G1 (G1 is the preset load, G1 ∈ (30N, 60N)). If it is determined that the vehicle is in a parked state, enter the parked heat insulation and sunshade control;

[0080] Step S320: When the light sensor signal value LS ≥ L1 (L1 is the set value, L1 ∈ (1600 Lus, 2000 Lus)) and the duration t ≥ t1 (t1 is the set value, t1 ∈ (2s, 6s)), the controller determines it is daytime, activates the vehicle heat insulation and sunshade system, and the controller controls the -100 control system to make all glasses reach the lowest light transmittance LT = LT0 (LT0 is the set value, LT0 ∈ (1%, 5%));

[0081] Step S330: When the light sensor signal value LS < L1 (L1 is the set value, L1 ∈ (1600 Lus, 2000 Lus)) and the duration t ≥ t1 (t1 is the set value, t1 ∈ (2s, 6s)), the controller determines it is night, and turns off the vehicle heat insulation and sunshade system; the vehicle glass returns to the set maximum light transmittance LT = LT3, (LT3 is the set value, LT3 ∈ (80%, 95%)

[0082] In some examples, the above method further includes:

[0083] When the load information corresponding to the rear seat is less than the above preset load and the above ambient brightness information is higher than the above preset brightness, determine the first light transmittance and the second light transmittance corresponding to the rear windows as the above minimum light transmittances according to the above ambient brightness information and the preset relationship between light transmittance and light.

[0084] It should be noted that there is an unclear "所" in the original text at line 13 which might be a typo. I've translated it as best as possible while keeping it in the translation.For example, if the load information of the rear seats is less than the preset load, there are no passengers in the rear. If the ambient brightness information is higher than the preset brightness, the first and second light transmittance of the rear windows are guaranteed to be the minimum light transmittance. Since there are no passengers in the rear and the driver will not observe the road conditions through the rear windows, the rear windows are controlled to use the minimum light transmittance for sun shading to improve the sun shading effect.

[0085] In some examples, the above method also includes:

[0086] The first and second light transmittance of the passenger-side window are the same as those of the driver-side window.

[0087] For example, when the ambient brightness is higher than the preset brightness, regardless of whether there is a passenger in the front passenger seat, the first and second light transmittance of the front passenger window are controlled to be the same as those of the driver's seat, ensuring that the driver can observe the road conditions behind through the rearview mirror.

[0089] Acquisition unit 21 is used to acquire ambient brightness information;

[0090] The first control unit 22 is used to control the first light transmittance of the road condition observation area glass based on the ambient brightness information, wherein the road condition observation area glass is the glass corresponding to the area below a preset height between the windshield and the movable window glass;

[0091] The second control unit 23 is used to control the second light transmittance of the glass in the non-road observation area based on the ambient brightness information. The glass in the non-road observation area refers to the glass in the area below a preset height of the windshield and movable window glass, the fixed window glass, and the rear windshield glass. The second light transmittance is less than or equal to the first light transmittance.
