[0052] In the daily use of vehicles, strong light exposure has caused great trouble to people: first, there is strong light during driving. The sources of strong light include strong sunlight and high beams of oncoming vehicles. Strong light exposure can cause glare. Drivers dazzled by strong light can easily lose their vision in a short period of time, posing a hidden danger to road traffic safety; second, when temporarily parking in the open air, strong sunlight exposure will not only affect the driver's line of sight, but also cause the temperature inside the car to rise sharply, seriously damaging the comfort of the vehicle environment.

[0053] In the related art, the dimming area of ​​the vehicle windshield can be set and the transmittance of the dimming area can be adjusted to reduce the impact of strong light exposure. However, the dimming area needs to be set manually by the driver, and there are problems such as complicated procedures and poor flexibility. At the same time, in the related art, the driving light environment can also be judged by weather, environment and external vehicle information. However, the light intensity in different viewing areas of the vehicle windshield is different. Local strong light exposure will cause the overall field of view to darken, which may cause blind spots in the driver's field of view, thereby increasing driving risks and having a problem of low accuracy.

[0054] The embodiment of the present application provides a control method for a vehicle windshield. First, the target eye position area of ​​the driver and passenger is determined through the seat sensor information of the vehicle. Then, in at least one grid unit of the vehicle windshield, the dimming area is determined through the target eye position area. Finally, the transmittance of the dimming area is controlled based on the light exposure information of the vehicle at the current position. On the one hand, the target eye position area can be automatically adapted through the seat sensor information, and the driver does not need to manually set the dimming area, which simplifies the process of the control method and improves the flexibility of the control method. On the other hand, by adjusting the transmittance of the determined dimming area, the dimming rate of a part of the vehicle windshield can be changed, which can reduce the possibility of glare due to the overall field of view being dimmed due to local strong light exposure, thereby improving the accuracy of the control method and driving safety.

[0055] Below, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application.

[0056] Figure 1 A schematic diagram of the implementation process of a vehicle windshield control method provided in an embodiment of the present application Figure 1 ,like Figure 1 As shown, the method includes steps S101 to S103, wherein:

[0057] Step S101, determining the target eye position area of ​​the driver and passenger based on the seat sensor information of the vehicle.

[0058] Here, the seat sensor may include but is not limited to: at least one of a pressure sensor, an ultrasonic sensor, an optical sensor, a capacitive sensor, etc. The seat sensor information may include but is not limited to: at least one of: pressure distribution on the seat, the angle of the seat back, the height of the seat, the distance between the seat and the footrest, etc.

[0059] The target eye position area refers to the area where the driver's line of sight is focused on in the vehicle windshield. The driver may be at least one. In some embodiments, the driver may be a front-row driver. The front-row driver may be a person sitting in the main driver's seat or a person sitting in the co-pilot's seat.

[0060] In some embodiments, the head position of the driver and passenger can be determined based on the vehicle's seat sensor information, and then the eye position can be determined from the head position. The eye position is then projected onto the vehicle windshield in combination with the distance between the seat and the pedals to obtain a projection area, which can then be used as the target eye position area.

[0061] In some implementations, after the seat is adjusted, seat sensor information measured by a seat integrated sensor may be acquired, and then the target eye position area may be estimated based on the seat sensor information.

[0062] In some implementations, the height of the occupant may be determined based on the seat sensor information, and then the target eye position area may be determined based on the height of the occupant.

[0063] In some embodiments, a first eye position area may be determined based on seat sensor information, a second eye position area may be determined based on the vehicle's mirror angle information, and then a target eye position area may be determined based on the first eye position area and the second eye position area.

[0064] Step S102, based on the target eye position area, determine the dimming area in the vehicle windshield; wherein the vehicle windshield includes at least one grid unit, and each grid unit is arranged in a corresponding arrangement manner.

[0065] Here, the vehicle windshield can use electrochromic glass. Electrochromic glass is made based on electrochemical principles. The color-changing function of electrochromic glass is mainly realized by the electrolyte layer and the color-changing ion membrane. When powered on, the electrolyte in the electrolyte layer undergoes an ionization reaction. The electrolyzed ions move to the energized transparent conductors with a potential difference on both sides according to the potential. When the ions are deposited on the color-changing ion membrane, the light transmittance can be changed.

[0066] The dimming area refers to the area of ​​the vehicle windshield that needs to adjust the transmittance, and the number of the dimming area can be at least one. In some embodiments, the dimming area can be a partial area of ​​the vehicle windshield, or it can be the entire area of ​​the vehicle windshield. In some embodiments, the target eye position area can be used as the dimming area.

[0067] In some embodiments, dimming areas may be determined in a windshield corresponding to a main driving area of ​​the vehicle and / or a windshield corresponding to a co-pilot area of ​​the vehicle, respectively, based on a target eye position area of ​​the driver or occupant.

[0068] In some embodiments, when both the main driver and the front passenger seat of the vehicle are passengers, corresponding dimming areas can be determined for the main driver and the front passenger seat in the vehicle windshield, respectively.

[0069] In some embodiments, the vehicle windshield includes at least one grid unit, and each grid unit is arranged in a corresponding arrangement. The light transmittance of the vehicle windshield corresponding to each grid unit can be individually controlled.

[0070] In some embodiments, the vehicle windshield includes a main driver's windshield and other area windshields. At least one grid unit of the main driver's windshield can be set using a first arrangement method, and at least one grid unit of the other area vehicle windshield can be set using a second arrangement method; wherein the first arrangement method and the second arrangement method are different.

[0071] In some embodiments, in response to receiving a preset operation on a central control screen of a vehicle, the dimming area can be adjusted to obtain an adjusted dimming area.

[0072] Step S103, based on the light exposure information of the vehicle at the current position, the light transmittance of the dimming area is controlled.

[0073] Here, the light exposure information refers to the light exposure condition of the vehicle at the current position. The light exposure information may include but is not limited to: at least one of sunlight exposure information, light exposure information, sensor information, etc.

[0074] Sunlight exposure information refers to the sunlight exposure of the vehicle at the current location. In some embodiments, the sunlight exposure information can be represented by light intensity. Light exposure information refers to the external vehicle light exposure of the vehicle at the current location. In some embodiments, the light exposure information can be represented by light intensity. Sensor information refers to the light exposure detected by the sensor when the vehicle is at the current location. In some embodiments, the sensor information can be represented by light intensity.

[0075] In some embodiments, a first correspondence between light exposure information and control logic may be established. After obtaining the light exposure information of the vehicle at the current position, the control logic corresponding to the light exposure information at the current position may be determined according to the first correspondence, thereby controlling the light transmittance of the dimming area. The control logic may include, but is not limited to, reducing, increasing, etc.

[0076] In some embodiments, the external light intensity of the vehicle at the current position may be determined based on the light illumination information, and then the light transmittance of the dimming area may be controlled based on the external light intensity and the light intensity threshold.

[0077] In the embodiment of the present application, first, the target eye position area of ​​the driver and passenger is determined through the seat sensor information of the vehicle, then, in at least one grid unit of the vehicle windshield, the dimming area is determined through the target eye position area, and finally, the transmittance of the dimming area is controlled based on the light exposure information of the vehicle at the current position. On the one hand, the target eye position area can be automatically adapted through the seat sensor information, without the driver having to manually set the dimming area, which simplifies the process of the control method and improves the flexibility of the control method; on the other hand, by adjusting the transmittance of the determined dimming area, the dimming rate of part of the vehicle windshield can be changed, which can reduce the possibility of glare due to the overall field of vision being dimmed due to local strong light exposure, thereby improving the accuracy of the control method and driving safety.

[0078] In some implementations, step S101 includes step S11 and step S12, wherein:

[0079] Step S11, determining the height of the driver and passenger based on the seat sensor information.

[0080] Here, the height of the driver and passenger may be any suitable size, for example, 165 cm (centimeter), 182 cm, etc.

[0081] In some embodiments, the weight of the occupant may be inferred based on the pressure distribution on the seat in the seat sensor information, and then the height of the occupant may be inferred based on the angle of the seat back, the height of the seat, and the distance between the seat and the footrest.

[0082] In some embodiments, the seat height of the occupant can be inferred based on the seat height in the seat sensor information, and then combined with ergonomic data, the height of the occupant can be inferred. The seat height refers to the vertical distance from the seat surface to the top of the occupant's head. In implementation, the ergonomic data can be that the average seat height of the occupant is about 55% to 60% of the height.

[0083] Step S12, determining the target eye position area based on the height of the driver or passenger.

[0084] Here, the head position of the driver and occupant may be determined based on the height of the driver and occupant, and then the target eye position area may be determined based on the head position of the driver and occupant.

[0085] In some embodiments, the eye position of the driver and passenger can be determined based on the height of the driver and passenger in combination with ergonomic data, and then the target eye position area is determined based on the eye position of the driver and passenger in combination with the distance between the seat and the pedal. In implementation, the ergonomic data can be that the average eye height of the driver and passenger is about 10% to 15% of the height. The eye height refers to the vertical distance from the ground to the eyes of the driver and passenger.

[0086] In some embodiments, since the actual seating position of the driver and passenger is not necessarily the center area of ​​the vehicle seat, when determining the target eye position area based on the height of the driver and passenger, the pressure distribution on the seat in the seat sensor information can be used to determine the specific seating position of the driver and passenger, and then the target eye position area can be adjusted horizontally to the left or right according to the specific seating position of the driver and passenger.

[0087] In the implementation manner of the present application, the target eye position area is determined by the height of the driver and passenger determined by the seat sensor information. The target eye position area can be determined automatically without manual determination of the target eye position area, thereby improving the convenience of the control method.

[0088] In some embodiments, step S101 includes steps S13 to S15, wherein:

[0089] Step S13: determining a first eye position area based on the seat sensor information.

[0090] Here, the first eye position area refers to the area on the vehicle windshield where the driver's line of sight is focused, determined based on the seat sensor information.

[0091] The seat sensor may include but is not limited to: at least one of a pressure sensor, an ultrasonic sensor, an optical sensor, a capacitive sensor, etc. The seat sensor information may include but is not limited to: at least one of: pressure distribution on the seat, the angle of the seat back, the height of the seat, the distance between the seat and the footrest, etc.

[0092] In some embodiments, the head position of the driver and passenger can be determined based on the vehicle's seat sensor information, and then the eye position can be determined from the head position. The eye position is then projected onto the vehicle windshield in combination with the distance between the seat and the pedal to obtain a projection area, which can then be used as the first eye position area.

[0093] In some implementations, the height of the occupant may be determined based on the seat sensor information, and then the first eye position region may be determined based on the height of the occupant.

[0094] Step S14, determining a second eye position area based on the vehicle's reflector angle information.

[0095] Here, since the driver and passengers need to adjust the vehicle's reflector to a suitable angle to observe the road conditions before starting the vehicle, the second eye position area can be determined based on the reflector angle information of the vehicle.

[0096] The vehicle's reflector angle information may include, but is not limited to: at least one of: a horizontal angle of the reflector, a vertical angle of the reflector, and the like.

[0097] The second eye position area refers to the area of ​​the vehicle windshield where the driver's line of sight is focused, determined based on the reflector angle information. In some embodiments, the second eye position area and the first eye position area may be the same area or different areas.

[0098] In some embodiments, the above information can be projected based on the mirror angle information, combined with the fore-and-aft movement distance of the seat, the height of the seat, and the angle of the seat back, and the intersection area of ​​the projections of the above information can be selected, and then the intersection area can be used as the second eye position area.

[0099] In some implementations, a second correspondence between the reflector angle information and the eye position area may be established, and after the reflector angle information is acquired, the second eye position area may be determined according to the second correspondence.

[0100] Step S15, determining a target eye position area based on the first eye position area and the second eye position area.

[0101] Here, the target eye position area, the first eye position area, and the second eye position area may be the same or different.

[0102] In some implementations, a region with a larger area may be selected from the first eye position region and the second eye position region as the target eye position region, thereby determining the target eye position region.

[0103] In some implementations, an intersection area of ​​the first eye position area and the second eye position area may be determined, and then the intersection area is used as the target eye position area, thereby determining the target eye position area.

[0104] In some embodiments, the merged area corresponding to the first target eye position area and the second eye position area may be used as the target eye position area, or the union area corresponding to the first target eye position area and the second eye position area may be used as the target eye position area.

[0105] In the implementation manner of the present application, the target eye position area is jointly determined by the first eye position area determined by the seat sensor information and the second eye position area determined by the reflector angle information, thereby improving the accuracy of the target eye position area.

[0106] In some embodiments, step S15 includes step S151 or step S152, wherein:

[0107] Step S151: taking the merged area corresponding to the first eye position area and the second eye position area as the target eye position area.

[0108] Here, the first eye position area and the second eye position area may not overlap at all, therefore, the merged area corresponding to the first eye position area and the second eye position area may be used as the target eye position area, so that the target eye position area covers a larger area.

[0109] In some embodiments, a merged region corresponding to the first eye position region and the second eye position region may be determined by a region merging algorithm or a merging tool. The region merging algorithm may include but is not limited to: region growing method, region merging method, and region segmentation merging method.

[0110] Step S152: taking the union area corresponding to the first eye position area and the second eye position area as the target eye position area.

[0111] Here, the first eye position area and the second eye position area may overlap, and therefore, the union area corresponding to the first eye position area and the second eye position area may be used as the target eye position area, so that the target eye position area covers a larger area.

[0112] In some embodiments, the union area corresponding to the first eye position area and the second eye position area may be determined by performing an OR operation on the first eye position area and the second eye position area.

[0113] In some embodiments, the intersection and union area of ​​the first eye position area and the second eye position area can be calculated by calculating the intersection ratio of the first eye position area and the second eye position area, and the union area corresponding to the first eye position area and the second eye position area can be calculated.

[0114] In an embodiment of the present application, a merged area or a union area corresponding to the first eye position area and the second eye position area is used as a target eye position area. Taking into account different actual situations, while improving the target eye position area, the compatibility of the control method is also improved.

[0115] In some embodiments, the above method further includes step S104, wherein:

[0116] Step S104, in response to receiving a preset operation on the central control screen of the vehicle, adjusting the dimming area to obtain an adjusted dimming area.

[0117] Here, the central control screen is a screen in the vehicle with display and control functions. The central control screen can be any suitable screen, for example, a liquid crystal display (LCD), an organic light-emitting diode display (OLED), a mini LED display, a micro LED display, etc.

[0118] The preset operation may be any appropriate operation, such as click, double-click, long press, etc.

[0119] In some embodiments, when a preset operation is received in the central control screen of the vehicle to adjust the dimming area, the light intensity threshold can also be determined according to the received preset operation.

[0120] In some embodiments, the dimming area can be first determined in the grid unit of the vehicle windshield through the seat sensor information, and the dimming area determined by the seat sensor information can be used as the initial dimming area. The initial dimming area is then displayed in the central control screen of the vehicle, so that in response to a preset operation received on the central control screen of the vehicle, the initial dimming area can be edited in the grid unit of the vehicle windshield to determine the dimming area, and the dimming area determined in the central control screen of the vehicle can be used as the final dimming area.

[0121] Figure 2 A schematic diagram of a central control screen dimming interface provided in an embodiment of the present application, such as Figure 2 As shown, the vehicle windshield 21 is displayed in the central control screen 20, and the vehicle windshield 21 mainly includes two dimming areas: the main driver dimming area 22 and the co-driver dimming area 23. Among them, the main driver dimming area corresponds to the main visual area of ​​the main driver, and the co-driver dimming area corresponds to the main visual area of ​​the co-driver. The corresponding light intensity thresholds can be set for the main driver dimming area 22 and the co-driver dimming area 23 in the central control screen 20. This personalized design not only makes up for the error of the algorithm estimating the visual area, but also meets the diverse anti-glare needs of users. Users can not only customize the dimming area, but also customize the light intensity threshold according to their personalized needs. For example, users who like dark wind can lower the light intensity threshold of the entire vehicle windshield 21 to achieve the effect of wearing sunglasses, or, when temporarily parking and resting outdoors, users can adjust the light intensity threshold to the lowest value that can be set, which can not only help users avoid interference from external light when resting, but also protect the privacy and safety of the car to a certain extent.

[0122] In the implementation manner of the present application, by receiving a preset operation on the central control screen of the vehicle, the dimming area is adjusted to obtain an adjusted dimming area, so that the user can adjust the dimming area according to his or her own needs, thereby improving the flexibility of the dimming area.

[0123] In some embodiments, the vehicle windshield includes a main driver's windshield and other area windshields; the above method further includes step S105 and step S106, wherein:

[0124] Step S105, setting at least one grid unit of the main driver's windshield using a first arrangement method.

[0125] Here, in order to ensure driving safety, it is necessary to set at least one grid unit of the main driver's windshield using the first arrangement method alone.

[0126] The first arrangement refers to the arrangement of at least one grid unit of the main driver's windshield. The first arrangement is used to characterize the length and width of at least one grid unit of the main driver's windshield.

[0127] Step S106, using a second arrangement method to arrange at least one grid unit of a vehicle windshield in other areas; wherein the first arrangement method and the second arrangement method are different.

[0128] Here, the first arrangement refers to the arrangement of at least one grid unit of the windshield in other areas except the main driving area. The second arrangement is used to characterize the length and width of at least one grid unit of the windshield in other areas except the main driving area.

[0129] In some embodiments, the first arrangement is different from the second arrangement. The density of at least one grid unit of the main driver's windshield is greater than the density of at least one grid unit of the vehicle windshield in other areas.

[0130] Figure 3 A schematic diagram of a vehicle windshield provided in an embodiment of the present application, such as Figure 3 As shown, the vehicle windshield 30 includes a main driving windshield 31 and other area windshields 32 except the main driving. In the main driving windshield 31, at least one grid unit is arranged in a first arrangement, and in the other area windshield 32 except the main driving, at least one grid unit is arranged in a second arrangement. It can be seen that the at least one grid unit arranged in the first arrangement is more refined.

[0131] In an embodiment of the present application, different arrangements are used for at least one grid unit of the main driver's windshield and at least one grid unit of the windshield in other areas of the vehicle, which can make the driver's dimming area more accurate, thereby ensuring driving safety. At the same time, grid units can be arranged in other areas with a low density, reducing the cost of the windshield.

[0132] In some embodiments, the light exposure information includes at least one of the following: sunlight exposure information, light exposure information, and sensor information; step S103 includes steps S131 to S132, wherein:

[0133] Step S131, based on the light illumination information, determining the external light intensity of the vehicle at the current position.

[0134] Here, the external light intensity refers to the intensity of the light irradiated to the vehicle at the current position. The external light intensity can be any appropriate size, for example, 6000 Lux, 12000 Lux, etc.

[0135] The light exposure information may include, but is not limited to, at least one of: sunlight exposure information, light exposure information, sensor information, and the like.

[0136] In some embodiments, the light intensity corresponding to the sunlight illumination information, the lighting illumination information, and the sensor information can be determined to obtain at least one light intensity value, and then the external light intensity of the vehicle at the current position can be determined based on the at least one light intensity value.

[0137] In some embodiments, a maximum light intensity value may be selected from at least one light intensity value, and then the external light intensity of the vehicle at the current position may be determined based on the maximum light intensity value. In implementation, the external light intensity of the vehicle at the current position may be determined by the maximum light intensity value, the weighting / logarithm / index of the maximum light intensity value, etc.

[0138] In some embodiments, at least one light intensity value may be superimposed to obtain a total light intensity value, and then the total light intensity value is used as the external light intensity of the vehicle at the current position. In implementation, the external light intensity of the vehicle at the current position may be determined by the total light intensity value, weighted / logarithmic / indexed total light intensity value, etc.

[0139] In some embodiments, weight values ​​may be assigned to sunlight information, lighting information, and sensor information, respectively. Then, based on the weight values ​​corresponding to the sunlight information, lighting information, and sensor information, combined with the light intensities corresponding to the sunlight information, lighting information, and sensor information, the external light intensity of the vehicle at the current location is determined. In implementation, the sum of the weight values ​​corresponding to the sunlight information, lighting information, and sensor information may be a fixed value.

[0140] In some embodiments, when the first light intensity corresponding to the sunlight illumination information and the lighting illumination information and the second light intensity corresponding to the sensor information satisfy a deviation condition, the first light intensity can be used as the external light intensity; when the first light intensity corresponding to the sunlight illumination information and the lighting illumination information and the second light intensity corresponding to the sensor information do not satisfy the deviation condition, the second light intensity can be used as the external light intensity.

[0141] In some embodiments, a driving model may be established based on the surrounding information of the vehicle, and then the light exposure information may be acquired based on the driving model and the sensors of the vehicle.

[0142] In some embodiments, after establishing the driving model, the vehicle's geographic meteorological information and the vehicle's surrounding obstacle information can be determined based on the vehicle's location information and the driving model can be used to obtain sunlight information based on the geographic meteorological information, obtain lighting information based on the surrounding obstacle information, and obtain sensor information from the vehicle's sensors to obtain light information.

[0143] Step S132: Control the light transmittance of the dimming area based on the external light intensity and the light intensity threshold.

[0144] Here, the light intensity threshold is used to determine whether to control the light transmittance of the dimming area. The light intensity threshold can be any appropriate value, for example, 5000 Lux, 10000 Lux, etc.

[0145] The light transmittance of the dimming area refers to the percentage of the transparent light flux passing through the dimming area to the incident light flux. The light transmittance of the dimming area can be any suitable value, for example, 50%, 30%, etc.

[0146] In some implementations, when determining a dimming area, a light intensity threshold corresponding to the dimming area may be set simultaneously.

[0147] In some embodiments, the light intensity threshold can be set in the vehicle's central control screen dimming interface.

[0148] In some embodiments, different dimming areas correspond to different light intensity thresholds. For example, the dimming area for the main driver corresponds to the main visual area of ​​the main driver, and the light intensity threshold can be set to 5000 lux. For another example, the dimming area for the co-driver corresponds to the main visual area of ​​the co-driver, and the light intensity threshold can be set to 1000 lux.

[0149] In some embodiments, when the external light intensity and the light intensity threshold satisfy the threshold condition, the light transmittance of the dimming area is reduced, and when the external light intensity and the light intensity threshold do not satisfy the threshold condition, the light transmittance of the dimming area is increased or maintained. The threshold condition may be any suitable condition, for example, not less than the light intensity threshold, greater than the light intensity threshold, etc.

[0150] In some embodiments, when the light transmittance of the dimming region is controlled, the current passing through the dimming region may be adjusted to change the light transmittance of the dimming region.

[0151] In some embodiments, when the external light intensity is not less than the light intensity threshold, the transmittance of the dimming area is reduced, and when the external light intensity is less than the light intensity threshold, the transmittance of the dimming area is increased.

[0152] In an embodiment of the present application, the external light intensity and light intensity threshold of the vehicle are determined by light illumination information including a variety of information, and the transmittance of the dimming area is controlled, which can improve the accuracy of the external light intensity and accurately control the transmittance of the dimming area.

[0153] In some embodiments, the above method further includes step S107 and step S110, wherein:

[0154] Step S107, establishing a driving model based on the surrounding information of the vehicle.

[0155] Here, the vehicle's surrounding information may include but is not limited to: at least one of the relative position of external vehicles and the vehicle, lighting status information of external vehicles, map data of the current driving environment, real-time weather data of the current driving environment, etc.

[0156] In some embodiments, the relative position of the external vehicle and the vehicle and the lighting status information of the external vehicle can be obtained through the external vehicle body sensor integration. The map data of the current driving environment and the real-time weather data of the current driving environment can be obtained through the network. The external vehicle body sensor integration can include but is not limited to: at least one of an ultrasonic sensor, a laser radar sensor, a photosensitive sensor, etc. Among them, the photosensitive sensor is installed near the front grille of the vehicle.

[0157] Methods for establishing a driving model may include, but are not limited to: establishing a driving model based on the surrounding information of the vehicle through the DrivingGaussian method, establishing a driving model based on the surrounding information of the vehicle through the DriveMLM method, etc. For example, the DrivingGaussian method uses the surrounding information of the vehicle to gradually model the complex static background of the entire scene through incremental 3D Gaussian, and constructs a combined dynamic Gaussian graph to characterize each dynamic foreground object, restore their accurate position and occlusion relationship in the scene, and thus establish a driving model. For another example, the DriveMLM method integrates the world knowledge and reasoning capabilities of a large language model into the autonomous driving system, and realizes the establishment of a driving model based on the surrounding information of the vehicle in a real simulator.

[0158] Step S108, based on the location information of the vehicle, using the driving model, determine the geographic weather information of the vehicle and the surrounding obstacle information of the vehicle.

[0159] Here, the vehicle location information refers to information that can describe the current geographical location of the vehicle. The vehicle location information can be any appropriate information, such as street, longitude, latitude, etc.

[0160] In some implementations, the geographic location information of the vehicle may be obtained by acquiring the Global Positioning System (GPS) information of the vehicle.

[0161] The vehicle's geographic weather information refers to the weather data and terrain distribution of the vehicle's current location, etc. The vehicle's surrounding obstacle information refers to the relative position and lighting status information of external vehicles around the vehicle, etc.

[0162] In some embodiments, after the driving model is established, the vehicle's location information can be used as input information of the driving model. The driving model can be used to simulate the vehicle's geographic meteorological information and the vehicle's surrounding obstacle information, thereby determining the vehicle's geographic meteorological information and the vehicle's surrounding obstacle information.

[0163] In some embodiments, the driving model may include at least one data set, and the geographic meteorological information and surrounding obstacle information of the vehicle at the current location may be determined based on the at least one data set in the driving model.

[0164] Step S109, obtaining sunlight information based on geographic meteorological information, and obtaining lighting information based on surrounding obstacle information.

[0165] Here, the sunlight exposure information refers to the sunlight exposure condition of the vehicle windshield determined by the driving model. In some embodiments, the sunlight exposure information has a corresponding light intensity value.

[0166] In some implementations, the geographic meteorological information of the current location may be simulated based on the driving model, and then the sunlight exposure information of the current location of the vehicle may be inferred based on the geographic meteorological information.

[0167] The lighting information refers to the lighting conditions of the external vehicle lighting on the vehicle windshield determined by the driving model. In some embodiments, the lighting information has a corresponding light intensity value.

[0168] In some implementations, the surrounding obstacle information of the current location can be simulated according to the driving model, and then the sunlight exposure information of the current location of the vehicle can be inferred according to the surrounding obstacle information.

[0169] Step S110, acquiring sensor information from the vehicle's sensor.

[0170] Here, the driving model can infer the sunlight exposure and other vehicles' light exposure at the current location of the vehicle. For some sudden lighting conditions (for example, strong searchlights near the construction site or strong handheld flashlights by passers-by), the driving model may not be able to predict. In order to improve the sensitivity and accuracy of capturing sudden strong light, it is necessary to obtain sensor information from the vehicle's sensors.

[0171] The sensor of the vehicle can be a photosensitive sensor. In some embodiments, the photosensitive sensor can be arranged on the main driving instrument panel inside the vehicle.

[0172] In some implementations, the light intensity data most recently detected by the vehicle's sensor may be used as the sensor information.

[0173] In the implementation mode of the present application, the vehicle's location information is used to determine the geographic meteorological information and surrounding obstacle information using a driving model established using the vehicle's surrounding information, combined with the vehicle's sensors, to determine sunlight exposure information, lighting exposure information, and sensor information, and corresponding methods are used to determine different light exposure information, thereby improving the accuracy of the light exposure information.

[0174] In some embodiments, the light exposure information includes: sunlight exposure information, light exposure information, and sensor information; step S131 includes step S1311 and step S1312, wherein:

[0175] Step S1311: When the first light intensity corresponding to the sunlight illumination information and the lamp illumination information and the second light intensity corresponding to the sensor information satisfy a deviation condition, the first light intensity is used as the external light intensity.

[0176] Here, the first light intensity refers to the total light intensity corresponding to the sunlight illumination information and the light illumination information. The first light intensity can be any suitable size, for example, 3000 Lux, 6800 Lux, etc. The second light intensity refers to the light intensity corresponding to the sensor information. The second light intensity can be any suitable size, for example, 5000 Lux, 8100 Lux, etc.

[0177] The deviation condition is a condition for determining the external light intensity, and the deviation condition may include but is not limited to: similar size, a difference between the two being less than a preset value, and the same size.

[0178] Exemplarily, the deviation condition may be that the difference between the two is less than a preset value. When the difference between the first light intensity corresponding to the sunlight exposure information and the light exposure information and the second light intensity corresponding to the sensor information is less than a preset value, the first light intensity corresponding to the sunlight exposure information and the light exposure information and the second light intensity corresponding to the sensor information meet the deviation condition. At this time, the first light intensity is used as the external light intensity.

[0179] Step S1312: When the first light intensity corresponding to the sunlight illumination information and the lamp illumination information and the second light intensity corresponding to the sensor information do not satisfy the deviation condition, the second light intensity is used as the external light intensity.

[0180] Here, the deviation conditions may include but are not limited to: similar size, the difference between the two is less than a preset value, the size is the same, etc.

[0181] Exemplarily, the deviation condition may be of the same magnitude. When the magnitudes of the first light intensity corresponding to the sunlight exposure information and the light exposure information and the second light intensity corresponding to the sensor information are different, the first light intensity corresponding to the sunlight exposure information and the light exposure information and the second light intensity corresponding to the sensor information do not satisfy the deviation condition. In this case, the second light intensity is taken as the external light intensity.

[0182] In the implementation manner of the present application, through the first light intensity, the second light intensity and the deviation condition, the first light intensity or the second light intensity is used as the external light intensity, and the corresponding light intensity can be selected as the external light intensity under different lighting conditions, thereby improving the accuracy of the external light intensity.

[0183] In some implementations, step S132 includes step S1321 and step S1322, wherein:

[0184] Step S1321, when the external light intensity is not less than the light intensity threshold, reducing the light transmittance of the dimming area.

[0185] Here, when the external light intensity is not less than the light intensity threshold, it may cause dazzle to the driver and passengers, so it is necessary to reduce the light transmittance of the dimming area. The light transmittance of the dimming area can be any suitable value, for example, 50%, 30%, etc.

[0186] In some embodiments, when the transmittance of the dimming region is controlled, the current passing through the dimming region can be adjusted. The larger the current passing through the dimming region, the faster the ionization speed of the electrolyte layer in the dimming region, the stronger the color change effect of the color-changing ion membrane in the dimming region, and the lower the transmittance of the dimming region. Correspondingly, the smaller the current passing through the dimming region, the slower the ionization speed of the electrolyte layer in the dimming region, the weaker the color change effect of the color-changing ion membrane in the dimming region, and the higher the transmittance of the dimming region.

[0187] In some embodiments, when the light transmittance of the dimming region is reduced, the current passing through the grid cells of the dimming region may be increased.

[0188] Step S1322: when the external light intensity is less than the light intensity threshold, increase the light transmittance of the dimming area.

[0189] Here, when the external light intensity is less than the light intensity threshold, the driver and passengers may not be able to see the road conditions ahead clearly. Therefore, it is necessary to increase the transmittance of the dimming area.

[0190] In some embodiments, the external light intensity being less than the light intensity threshold may indicate that the strong light source disappears. In this case, the light shielding effect needs to be released, and therefore, the light transmittance of the dimming area needs to be increased.

[0191] In some embodiments, when the external light intensity is less than the light intensity threshold, the current passing through the grid units of the dimming area can be reduced, thereby increasing the light transmittance of the dimming area. In this way, the current can be reduced to save energy.

[0192] In some embodiments, the vehicle windshield has an upper limit value for light transmittance. When the light transmittance of the dimming area is increased, the light transmittance cannot be increased after reaching the upper limit value. The upper limit value for light transmittance may be set in the vehicle's central control screen, or may be determined by the physical properties of the vehicle windshield itself.

[0193] In the implementation manner of the present application, the transmittance of the dimming area is reduced when the external light intensity is not less than the light intensity threshold, and the transmittance of the dimming area is increased when the external light intensity is less than the light intensity threshold. The transmittance of the dimming area can be adjusted according to different actual conditions, and while reducing current to save energy, the shading effect after the disappearance of the strong light source can be eliminated, thereby improving the flexibility of the control method.

[0194] The following describes the application of the vehicle windshield control method provided in the embodiment of the present application in actual scenarios, taking a vehicle with a front windshield as an example.

[0195] In the daily use of vehicles, strong light exposure has caused great trouble to people: first, there is strong light during driving. The sources of strong light include strong sunlight and high beams of oncoming vehicles. Strong light exposure can cause glare. Drivers dazzled by strong light can easily lose their vision in a short period of time, posing a hidden danger to road traffic safety; second, when temporarily parking in the open air, strong sunlight exposure will not only affect the driver's line of sight, but also cause the temperature inside the car to rise sharply, seriously damaging the comfort of the vehicle environment.

[0196] In the related art, the dimming area of ​​the vehicle windshield can be set and the transmittance of the dimming area can be adjusted to reduce the impact of strong light exposure. However, the dimming area needs to be set manually by the driver, and there are problems such as complicated procedures and poor flexibility. At the same time, in the related art, the driving light environment can also be judged by weather, environment and external vehicle information. However, the light intensity in different viewing areas of the vehicle windshield is different. Local strong light exposure will cause the overall field of view to darken, which may cause blind spots in the driver's field of view, thereby increasing driving risks and having a problem of low accuracy.

[0197] The embodiment of the present application provides a control method for a vehicle windshield. First, the target eye position area of ​​the driver and passenger is determined through the seat sensor information of the vehicle. Then, in at least one grid unit of the vehicle windshield, the dimming area is determined through the target eye position area. Finally, the transmittance of the dimming area is controlled based on the light exposure information of the vehicle at the current position. On the one hand, the target eye position area can be automatically adapted through the seat sensor information, and the driver does not need to manually set the dimming area, which simplifies the process of the control method and improves the flexibility of the control method. On the other hand, by adjusting the transmittance of the determined dimming area, the dimming rate of a part of the vehicle windshield can be changed, which can reduce the possibility of glare due to the overall field of view being dimmed due to local strong light exposure, thereby improving the accuracy of the control method and driving safety.

[0207] Step S209: when the external light intensity is less than the light intensity threshold, increase the light transmittance of the dimming area.

[0213] Step S34, the central control screen adjusts the dimming area and light intensity threshold;

[0214] Step S35, estimating the sunlight exposure condition of the current route;

[0219] Here, the current environment sudden strong light exposure corresponds to the aforementioned sensor information. After executing steps S35 to S37, the external light intensity is determined based on the current route sunlight exposure, the current environment external vehicle light exposure, and the current environment sudden strong light exposure.

[0220] Step S38, determining whether the external light intensity exceeds the light intensity threshold;
