DETAILED DESCRIPTION

[0017] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0018] refer to Figure 1 , Figure 1 This is a step diagram of a control method for a sunshade provided in an embodiment of the present application, the method comprising the following steps: S11: Determine the eye position of the user according to the monitored light intensity.

[0019] In this embodiment, once the user occupies the position in the cab and starts the vehicle, the vehicle monitors the light intensity outside the vehicle. If the light intensity outside the vehicle is greater than the light intensity threshold, it can be determined that the light intensity at this time will affect the line of sight of the user driving the vehicle. Therefore, this implementation controls the stretching of the vehicle sunshade to resist the stimulation of the light at this light intensity to the human eye. Specifically, the vehicle obtains the user's eye position by capturing a facial image, and then determines the appropriate stretching position of the sunshade through the eye position. In addition, if the light intensity outside the vehicle is less than the light intensity threshold, it detects whether the user inputs a sunshade stretching instruction. If the user inputs a sunshade stretching instruction, the vehicle still detects the user's eye position to determine the stretching position of the sunshade, or controls the sunshade to stretch directly to the stretching position input by the user according to the stretching position manually input by the user.

[0020] S12: Determine a first stretching distance of the sunshade and a vertical light distance according to the eye position and the inclination angle of the front windshield of the vehicle.

[0021] In this embodiment, the sunshade of the vehicle is arranged at a position near the front windshield on the top of the vehicle. When the sunshade is stretched, it is stretched downward from the top of the front windshield along the front windshield. Figure 2 The embodiment shown also provides a schematic diagram of the movement trajectory of the sunshade. Therefore, in order to prevent light from passing through the top of the windshield and shooting at the user, and also to pave the way for the second stretching distance to be obtained later, the first stretching distance to which the sunshade is to be stretched is obtained in this embodiment. Specifically, the first stretching distance and the vertical light distance can be determined by the user's eye position and the inclination angle of the vehicle's windshield, wherein the first stretching distance refers to the distance from the light incident point left by the light that enters the user's eyes and is perpendicular to the windshield at the windshield to the top of the windshield, and the vertical light distance refers to the distance from the light incident point perpendicular to the user's eyes. In addition, an embodiment of the present application also provides a schematic diagram of the calculation of the movement stroke of the sunshade, as shown in FIG. Figure 3 As shown, in this Figure 3 In the figure, point A is the incident point of the light that enters the user's eyes and is perpendicular to the front windshield, and is also the critical point where the light just enters the user's eyes perpendicularly. S1 is the first stretching distance.

[0022] S13: Determine a second stretching distance according to the vertical light distance and the critical incident angle of the light.

[0023] S14: Determine a target stretching distance according to the first stretching distance and the second stretching distance.

[0024] In this embodiment, the critical incident angle refers to the critical incident angle of the light that enters the user's eyes on the front windshield, and is also the angle of the eyes that can be directly illuminated by the light within the user's field of view, such as Figure 3 The β in is the critical incident angle, and the range of the light on the front windshield corresponding to the critical incident angle is the second stretching distance, such as Figure 3 The distance from point B to point A in the figure and the area between point B and the bottom of the front windshield are all areas where light cannot directly enter the user's eyes, that is, the light irradiated in this area does not affect the user's vehicle driving. Specifically, when the critical incident angle of the light is determined, the second stretching distance can be obtained by the vertical light distance and the second stretching distance algorithm. Among them, the second stretching distance algorithm is:

[0025] Wherein, L is the vertical light distance, S2 is the second stretching distance, and β is the critical incident angle. After obtaining the first stretching distance and the second stretching distance, the target stretching distance can be obtained according to the sum of the first stretching distance and the second stretching distance, and the target stretching distance is also the sunshade length that the sunshade curtain is to be stretched.

[0026] S15: Controlling the sunshade to stretch to the target stretching distance.

[0027] After obtaining the target stretching distance of the sunshade, the vehicle controls the sunshade to stretch from the top of the front windshield until it stretches to the target stretching distance. In addition, after determining the target stretching distance of the user, the present embodiment can also memorize and save the target stretching distance corresponding to the user, and when the user occupies the driving position of the vehicle next time, after determining that the light intensity outside the vehicle is greater than the light intensity threshold, directly retrieve the target stretching position corresponding to the user to perform sunshade blocking and stretching.

[0028] Through the target stretching position of the sunshade provided in the present application, the sunshade can accurately block the light that directly enters the user's eyes, preventing the user from having a driving experience affected by the glare of light; at the same time, since the control and stretching of the sunshade of the present application is completely completed by the vehicle's autonomous control, the inconvenience of manual control of the stretching by the user is avoided.

[0029] In combination with the above embodiments, in one implementation, the present invention also provides a method for controlling a sunshade. In the method for controlling a sunshade for a vehicle, determining the critical incident angle of light includes steps S21 to S24: S21: determining a light incident point according to the light intensity distribution and the spot coefficient on the front windshield of the vehicle, wherein the light incident point is a point on the front windshield where the light intensity is greater than the product of the spot coefficient and the maximum light intensity.

[0030] S22: Determine the light incident area on the front windshield according to the light incident point.

[0031] In this embodiment, the vehicle is also provided with a front-view camera, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the position of a vehicle front-view camera provided in this embodiment. The front-view camera can obtain the light intensity corresponding to each position on the front windshield of the vehicle, and find the position point with the maximum light intensity from the light intensities corresponding to these positions. This position point is also the center position of the light spot formed by the light irradiating the front windshield. Through the maximum light intensity and the preset light spot coefficient, it can be determined that the position point on the front windshield where the light intensity is greater than the product of the light spot coefficient and the maximum light intensity, this position point is also the light incident point where light is incident. The light incident points on the front windshield gather to form an area, which is the light incident area on the front windshield. The light incident area indicates that the light intensity corresponding to the light in this area is relatively large. If it is directly irradiated into the user's eyes, it will have a greater impact on the user.

[0032] S23: Determine the incident light in the light incident area that enters the user's eyes according to the light incident area and the eye position.

[0033] S24: Determine the incident angle corresponding to the incident light that critically enters the user's eyes in the light incident area as the critical incident angle.

[0034] Specifically, in order to determine the light in the light incident area that can affect the user's eyes, that is, to determine the light that can enter the user's eyes, this embodiment determines the incident light that can enter the user's eyes through the light incident point according to the user's eye position and the light incident point in the light incident area. Then determine the critical incident light that can just enter the user's eyes, such as Figure 3 As shown in , the light passing through point B is the critical incident light entering the user's eyes, and even if part of the light between point B and the bottom of the front windshield belongs to the incident area, these lights cannot affect the user's eyes. The area that can cause an impact is the area between point B and point A. The incident angle corresponding to the incident light is determined as the critical incident angle.

[0035] In combination with the above embodiments, in one implementation, the present invention also provides a method for controlling a sunshade. In the method for controlling a sunshade for a vehicle, determining the eye position of the user according to the monitored light intensity includes steps S31 to S33: S31: Determine, according to current environmental data, a light intensity threshold corresponding to the current environmental data.

[0036] S32: Compare the monitored light intensity with the light intensity threshold to obtain a corresponding comparison result.

[0037] S33: Determine the eye position of the user according to the comparison result.

[0038] Specifically, considering that users have different requirements for light in different environments, this embodiment sets different light intensity thresholds for different environmental data. For example, in winter, the light inside the car is dim, and the user hopes that more light will enter the car to make the car brighter, so the light intensity threshold corresponding to winter is set higher; conversely, the light intensity threshold corresponding to summer is set lower; for example, in the morning, noon and evening of a day, if the temperature outside the car is low, since light can provide a certain amount of heat, the light intensity threshold is set lower, otherwise it is set higher.

[0039] After determining the environment in which the vehicle is located through the vehicle's current environment data, the light intensity threshold corresponding to the environment is determined based on the environment. The current light intensity of the monitored vehicle is compared with the light intensity threshold corresponding to the current environment to obtain the corresponding comparison result. If the comparison result shows that the light intensity is greater than the light intensity threshold, it is considered that the light at this time affects the user's driving experience, and the sunshade needs to be stretched to block the light, thereby obtaining the user's eye position.

[0040] In combination with the above embodiments, in one implementation, an embodiment of the present invention further provides a method for controlling a sunshade. In the method for controlling a sunshade for a vehicle, a first stretching distance and a vertical light distance of the sunshade are determined according to the eye position and the tilt angle of the front windshield of the vehicle, including steps S41 to S42: S41: Determine the visual height distance between the user's eyes and the roof according to the eye position.

[0041] S42: Determine a first stretching distance and the vertical light distance according to the visual height distance and the inclination angle of the vehicle front windshield.

[0042] Specifically, Figure 3 As shown, in order to obtain the first stretching distance S1, the distance from the user's eyes to the top of the vehicle can be determined by the user's eye position, which is also the visual height distance. The first stretching distance can be calculated by the visual height distance and the inclination angle of the vehicle's front windshield and the first stretching distance algorithm. The first stretching distance algorithm is: , where H is the visual height distance, α is the tilt angle of the front windshield, and S1 is the first stretching distance. In addition, when the visual height distance and the tilt angle of the front windshield of the vehicle are obtained, the vertical light distance can be determined by the vertical light distance algorithm, which is: , where L is the vertical light distance.

[0043] In combination with the above embodiments, in one implementation, the present invention also provides a method for controlling a sunshade. In the method for controlling a sunshade for a vehicle, the method further includes steps S51 to S53: S51: When the vehicle is in an ignition-off state, predict the parking time of the vehicle based on the vehicle's positioning data and historical driving data.

[0044] S52: Determine the weather conditions during the parking time according to the weather data of the location of the vehicle.

[0045] S53: According to the weather conditions, the sunshade is controlled in a target manner corresponding to the weather conditions.

[0046] Since cars in outdoor parking lots are often exposed to sunlight, especially the front windshield, and sunlight shines into the car through the front windshield, the seats are exposed to the sun for a long time, causing the vehicle interior to discolor and age. Therefore, in order to avoid the interior of the vehicle being affected by sunlight, this embodiment obtains the weather conditions outside the vehicle when the vehicle is in the off state to determine whether to extend the sunshade during the vehicle off period. Specifically, in this embodiment, it can be determined whether the vehicle is in the off state by determining whether the vehicle power signal is switched from OFF gear to ON gear, and the driving gear is switched from non-P gear to P gear, and the driver's seat occupancy signal is detected as unoccupied.

[0047] When it is determined that the vehicle is in the off state, the current positioning data and historical driving data of the vehicle are obtained to predict the parking time of the vehicle at the current position through the historical driving data. Then the weather data of the current position of the vehicle is obtained to determine the weather conditions during this parking time according to the parking time, such as whether the weather conditions during this period are rainy, sunny, cloudy, or hail. After determining the weather conditions during the parking time, the target control of the sunshade is selected and determined according to the weather conditions. For example, when the weather condition is sunny, the sunshade is selected to be stretched, and the stretching distance can be determined according to the light intensity outside the vehicle. When the light intensity is large, the sunshade is selected to be stretched to 80% of the fully stretched state. When the light intensity is small, the sunshade is selected to be stretched to 50% of the fully stretched state. When the weather condition is rainy or cloudy, the sunshade is selected not to be stretched. If the sunshade is installed on the outside of the vehicle, when the weather condition is hail, you can choose to control the sunshade to be fully extended to prevent the hail from directly hitting the front windshield and causing greater economic losses.

[0048] In combination with the above embodiments, in one implementation, the present invention also provides a method for controlling a sunshade. In the method for controlling a sunshade for a vehicle, the method further includes steps S61 to S64: S61: Determine the light intensity of the main driving area and the co-pilot area in the vehicle.

[0049] S62: Determine a light intensity difference value according to the light intensity of the main driving area and the light intensity of the co-pilot area in the vehicle.

[0050] S63: Determine the stretching degree corresponding to the light intensity difference value.

[0051] S64: Controlling the passenger's sunshade to stretch to a stretching position corresponding to the stretching degree.

[0052] Since bright light in the car easily attracts people's attention, in order to prevent the sunshade of the main driver from being stretched to the target stretching distance, but the sunshade of the co-pilot is not stretched, causing light to penetrate the co-pilot cabin and attract the attention of the main driver, thereby making the main driver unable to concentrate and prone to dangerous driving. This embodiment also proposes a control method for the co-pilot sunshade.

[0053] Specifically, the light intensity of the main driving area and the co-pilot area in the car is detected respectively, and the corresponding detection results are obtained. After obtaining the light intensity of the main driving area and the light intensity of the co-pilot area in the car, the light intensity difference between the two can be determined. Each light intensity difference value has a corresponding light intensity interval, and each light intensity interval has a corresponding degree of stretching of the co-pilot sunshade. For example, if the light intensity difference value is 325LUX, the light intensity interval corresponding to the light intensity difference value is 300-400LUX, and the degree of stretching corresponding to the light intensity interval is 20% of the fully stretched state of the sunshade. After determining the degree of stretching corresponding to the light intensity difference value, the co-pilot sunshade is controlled to stretch to the stretching position corresponding to the degree of stretching. In addition, the sunshade in the co-pilot area can also be manually adjusted by instructions input by the user, which will not be repeated here.

[0054] In combination with the above embodiments, in one implementation, the present invention also provides a method for controlling a sunshade. In the method for controlling a sunshade for a vehicle, the method further includes steps S71 to S74: S71: Obtain the user's identity information.

[0055] S72: Establishing a mapping relationship between the identity information and the determined target stretching position.

[0056] S73: before determining the eye position of the user, the method further includes: determining whether there is a target stretching position corresponding to the identity information in the mapping relationship according to the identified identity information of the current user; S74: When there is a target stretching position corresponding to the identity information, control the sunshade to be stretched to the target stretching position.

[0057] In order to avoid repeated calculation of the target stretching position to which the sunshade needs to be stretched when the same user is driving a vehicle, this embodiment also obtains the identity information corresponding to the user's face when determining the user's eye position through the in-vehicle camera. Figure 5As shown, it is a flow chart of a sunshade control strategy provided by the present embodiment. After obtaining the identity information of the user, the target stretching position calculated by the eye position of the user is matched with the identity information of the user to establish a corresponding mapping relationship. When the user sits in the driving seat next time and determines that the light intensity outside the vehicle exceeds the light intensity threshold and the sunshade needs to be stretched, after obtaining the identity information of the user through the camera inside the vehicle, first determine whether there is a target stretching position corresponding to the identity information of the user in the mapping relationship stored in the vehicle. If there is a target stretching position corresponding to the identity information, the vehicle can directly retrieve the target stretching position corresponding to the user and control the sunshade to stretch to the target stretching position. This method effectively saves the calculation amount of the vehicle and makes it more convenient and quick to control the stretching of the sunshade.

[0058] Based on the same inventive concept, an embodiment of the present application provides a control system for a sunshade, referring to Figure 6 , Figure 6 is a schematic diagram of a sunshade control system proposed in an embodiment of the present application, wherein the system includes a vehicle-mounted terminal and a vehicle body controller; The vehicle-mounted terminal comprises: An eye position determination module, used to determine the user's eye position based on the monitored light intensity; A first stretching distance determination module, used to determine a first stretching distance of the sunshade and a vertical light distance according to the eye position and the inclination angle of the front windshield of the vehicle; A second stretching distance determination module, used to determine a second stretching distance according to the vertical light distance and the critical incident angle of the light; a target stretching distance determining module, configured to determine a target stretching distance according to the first stretching distance and the second stretching distance; The body controller is used to control the sunshade to be stretched to the target stretching distance.
