DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0018] A specific embodiment of the present invention discloses an automatic control method for a vehicle sunshade. Figure 1 ,include: S301, obtaining vehicle positioning information, vehicle driving route information and weather status information; S302, using the edge of the sunshade movable end as the first reference point and the driver's chin as the second reference point, determining the sunlight angle information and the relative position information between the driver's chin and the sunshade movable end; S303, determining the moving direction and moving distance of the sunshade according to the vehicle positioning information, the vehicle driving route information, the weather status information, the sunlight angle information and the relative position information between the driver's chin and the sunshade mobile end.

[0019] In this embodiment, the vehicle positioning information, vehicle driving route information and weather status information are first obtained; then the edge of the sunshade mobile end is used as the first reference point, and the driver's head chin is used as the second reference point to determine the sunlight angle information and the relative position information between the driver's chin and the sunshade mobile end; finally, the vehicle sunshade control model is constructed based on the vehicle positioning information, vehicle driving route information, weather status information, sunlight angle information and the relative position information between the driver's chin and the sunshade mobile end, and the moving direction and moving distance of the sunshade are determined based on the vehicle sunshade control model. The driver's sudden movement amplitude during driving should be limited, with the driver's chin as the reference point that is not illuminated, leaving a certain amount of driver movement margin. When light interferes with driving, the driver instinctively avoids the sunlight backward and upward, and the predictive adjustment of the sunshade increases the space for avoiding light. If the sunshade is not predictively adjusted, the driver may not be able to avoid strong light even if he leans to the back of the seat.

[0020] It should be noted that by obtaining the vehicle positioning information, the weather status information of the vehicle's environment can be further accurately determined, and by obtaining the vehicle's driving route information, the sunlight information corresponding to the vehicle's environment at future moments can be predicted in advance, so that the intensity and direction of light to which the driver will be exposed can be predictably perceived, and the movement of the sunshade can be adjusted in advance to avoid the problem of direct sunlight affecting the driver's vision.

[0021] In step S102, the in-car camera continuously collects the driver's image, defines a certain reference point, defines a certain fixed reference object within the camera's visible range as the reference point, defines the driver's side seat belt fixed point as the reference point (point A), and uses the DMS driver monitoring system to analyze and calculate in real time to identify the driver's head position, defines the midpoint of the lower edge of the facial recognition frame as the driver's head jaw position (point B), defines the lower left corner of the fixed camera's capture screen as the coordinate origin, the front of the vehicle is the positive direction of the X axis, the left of the vehicle is the positive direction of the Y axis, and the top of the vehicle is the positive direction of the Z axis. Then the coordinate value of point A should be the fixed coordinate (Xa, Ya, Za), and the coordinate value of point B is (Xb, Yb, Zb), that is, the position information of point B can be calculated.

[0022] It should be noted that setting the second reference point at the driver's chin can ensure that there is a certain reserve when the shading system is turned on.

[0023] In step S103, the sunshade position is predictively adjusted by analyzing and calculating the vehicle's current driving direction and expected driving direction, the vehicle's pitch angle signal, the longitudinal slope signal of the road ahead, the current weather light intensity signal, the light direction signal, and the driver's head position coordinate signal.

[0024] In some embodiments, the method of determining the sunlight angle information and the relative position information between the driver's chin and the movable end of the sunshade using the edge line of the movable end of the sunshade as the first reference point and the driver's chin as the second reference point includes: Taking the edge of the movable end of the sunshade as the first reference point, determining the sunlight angle information as the angle information between the direct light formed by the sunlight passing through the first reference point and the horizontal plane; Taking the edge of the movable end of the sunshade as the first reference point and the driver's chin as the second reference point, the relative position information of the driver's chin and the movable end of the sunshade is determined as the angle information between the straight line formed by the line connecting the first reference point and the second reference point and the ground plane; The angle between the ground plane and the horizontal plane is defined as the reference angle information.

[0025] In this embodiment, the angle of sunlight can be obtained by the angle information between the direct light formed by the sunlight passing through the first reference point (the edge of the movable end of the sunshade) and the horizontal plane. This can help analyze how sunlight affects the driver's field of vision and the light inside the car in different time periods. Specifically, the relationship between the angle formed by the sunlight and the horizontal plane will affect the use effect and necessity of the sunshade. The relative position of the driver's chin and the sunshade is determined by the angle information between the straight line formed by the connection of the first reference point and the second reference point and the ground plane. This angle information can be used to determine the sensitivity of the driver's sitting posture, head position, etc. to the direction of sunlight. For example, if the angle is large, it may mean that the driver is facing more direct sunlight.

[0026] In a specific embodiment, see Figure 2 and Figure 3 , the angle between the direct light formed by the sunlight passing through the first reference point and the horizontal plane is β, the reference angle is γ, and the relative position information between the driver's chin and the movable end of the sunshade is that the angle between the straight line formed by the line connecting the first reference point and the second reference point and the ground plane is α.

[0027] In some embodiments, the method of determining the sunlight angle information by taking the edge line of the movable end of the sunshade as the first reference point and taking the lower jaw of the driver's head as the second reference point further includes: Taking the left A-pillar line and the right A-pillar line of the vehicle as the third reference, define a first front angle between the driver's gaze and the left A-pillar line and the front of the vehicle, and a second front angle between the driver's gaze and the right A-pillar line and the front of the vehicle; The sunlight angle information includes sunlight direct angle information, and the sunlight direct angle information is that the horizontal angle between the front direction of the vehicle and the projection of the sunlight direction on the ground is between the first front angle and the second front angle.

[0028] In this embodiment, in order to achieve optimal lighting and safety conditions, the direction of sunlight should be within the range where the driver can safely see the front without being blocked by the A-pillar.

[0029] By defining and measuring these basic angles (including the angle between the driver's gaze and the A-pillar and the angle of sunlight), the visual environment during driving can be analyzed and optimized more comprehensively. This method can not only enhance driving safety, but also improve the in-car driving experience, while providing data support for the development of automatic shading systems or driver assistance systems. By understanding the relationship between these angles, automakers can design more scientific and reasonable in-car spaces and safety systems.

[0030] For details, please refer to Figure 4 , define the horizontal angle between the projection of the vehicle's front direction and the sunlight direction on the ground as θ. When the seat is adjusted to the frontmost position, the driver sits normally, the angle between the line connecting the eyes and the left A-pillar and the front of the vehicle is θL, and the angle between the line connecting the eyes and the left A-pillar and the front of the vehicle is θR. This angle is calibrated with the vehicle. When the sun is on the left side of the driver's front direction, if the θ angle is greater than θL, it is judged that it is in a non-direct light state; when the sun is on the right side of the driver's front direction, if the θ angle is greater than θR, it is judged that it is in a non-direct light state. In the non-direct light state, the sunshade does not need to move. When the θ angle is less than θL or θR, it is judged that it is in a direct light state.

[0031] In some embodiments, determining the moving direction and moving distance of the sunshade further includes: Determine the solar radiation intensity value within a preset range according to the weather status information, the vehicle positioning information and the vehicle driving route information; According to the relationship between the solar light intensity value and the intensity threshold, a vehicle sunshade control model is established; If the sunlight intensity value is greater than the intensity threshold, the vehicle sunshade control model controls the moving direction and moving distance of the sunshade.

[0032] In this embodiment, after the vehicle is started, the user turns on the predictive sunshade control system switch, the user sets the navigation route, and the system determines the weather and light intensity values ​​at the vehicle's location. When the weather information shows that the light intensity within a radius of 30 kilometers is greater than 800lx (generally exceeding 800lx will be dazzling) or a certain set value, the predictive sunshade system function is activated, otherwise the function is not activated.

[0033] In some embodiments, determining the moving direction and moving distance of the sunshade further includes: The angle information of the sunlight is the angle information between the direct light formed by the sunlight passing through the first reference point and the horizontal plane as the first light path angle information; The angle information formed by the straight line formed by the first reference point and the second reference point connected with the ground plane is the second optical path angle information; A vehicle sunshade control model is established according to the relationship between the first light path angle information, the second light path angle information and the reference angle information; If the first light path angle information is less than the sum of the second light path angle information and the reference angle information, the vehicle sunshade control model controls the moving direction and moving distance of the sunshade.

[0034] In this embodiment, if the vehicle navigation β<α+γ, the driver's face will be directly exposed to the sun, then the predictive sunshade system ECU will control the electric sunshade to rise and fall until β=α+γ. Because the electric sunshade is adjusted by motor drive, it takes a certain amount of time to adjust, so the predictive sunshade system analyzes the vehicle navigation route and performs predictive sunshade. When the vehicle speed is 50km / h-80km / h, the longitudinal angle between the line from the driver's head chin position to the lower edge of the sunshade and the front and rear direction of the vehicle is defined as α, and the vehicle is defined to move forward 50m according to the navigation route. At that time, the horizontal angle between the front direction of the vehicle and the direction of sunlight on the ground is θ1, and the angle between the projection of the illumination direction in the vertical direction and the horizontal plane at that time is β1, and the road slope at that time is γ1. If θ1 is less than θL or θR, and β1<α+γ1, the predictive sunshade system immediately controls the electric sunshade to adjust until β1=α1+γ1, and α1 is the state after α adjustment. Continue driving. When θ1 is less than θL or θR, and there is no situation where β1<α+γ1 within 1km of the future route, the predictive sunshade system immediately controls the electric sunshade to adjust until β=α+γ. Continue driving. When θ is always greater than θL and θR for 1km, the sunshade is retracted to the initial position. When the vehicle exits navigation or the navigation trip ends, the predictive sunshade function exits the activation state. At this time, if the sunshade is not in the initial position, it maintains the current position. When the predictive sunshade switch is turned off, the predictive sunshade function is turned off.

[0035] Based on the above-mentioned automatic control device for vehicle sunshade, the embodiment of the present invention further provides an automatic control device for vehicle sunshade, please refer to Figure 5 ,include: The acquisition module 510 is used to acquire vehicle location information, vehicle travel route information and weather status information; The position determination module 520 is used to determine the sunlight angle information and the relative position information between the driver's chin and the movable end of the sunshade curtain by taking the edge line of the movable end of the sunshade curtain as the first reference point and the driver's chin as the second reference point; The control module 530 is used to determine the moving direction and moving distance of the sunshade according to the vehicle positioning information, the vehicle driving route information, the weather status information, the sunlight angle information and the relative position information between the driver's chin and the sunshade mobile end.
