Description

Technical field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a sun visor assembly, a control method, and a vehicle. [Background Technology]

[0002] Currently, if a user feels direct sunlight in their eyes while driving, they can only manually adjust the sun visor to block the direct sunlight. However, this method has the following two problems: First, the user often adjusts the sun visor only after they feel the sunlight directly in their eyes, which has a lag in the timing of adjustment and can easily lead to safety accidents. Second, when manually adjusting the sun visor, the user's eyes are diverted to the sun visor, and they ignore potential dangers around the vehicle, which can easily lead to safety accidents. [Summary of the invention]

[0003] The embodiments of the present application provide a sun visor assembly, a control method, and a vehicle, which can automatically and timely adjust the rotation angle of the sun visor body, thereby meeting the needs of frontal shading and side shading and improving driving safety.

[0004] In a first aspect, an embodiment of the present application provides a sun visor assembly, the sun visor assembly comprising:

[0005] Sun visor body;

[0006] A driving unit, used for outputting a driving force in a target direction outward;

[0007] A rotating shaft, wherein one end of the rotating shaft is fixedly connected to the sun visor body, the other end of the rotating shaft is magnetically connected to the driving part, and the other end of the rotating shaft is a spherical structure.

[0008] In the embodiment of the present application, the sun visor assembly includes a driving part, a rotating shaft and a sun visor body connected in sequence. As long as the driving part outputs a driving force in the target direction, it can drive the spherical structure end of the rotating shaft to rotate in the corresponding direction, and then drive the sun visor body fixedly connected to the other end of the rotating shaft to rotate accordingly, thereby realizing automatic adjustment of the rotation angle of the sun visor body, which not only meets the needs of front shading and side shading, but also improves driving safety.

[0009] Optionally, the driving unit includes:

[0010] A spherical motion surface connected to the spherical structure of the rotating shaft by magnetic attraction;

[0011] The driving motor is used to drive the spherical motion surface to output driving force in the target direction.

[0012] In an embodiment of the present application, the driving part includes a driving motor and a spherical moving surface, which is magnetically connected to the spherical structure end of the rotating shaft. As long as the driving motor drives the spherical moving surface to output a driving force in the target direction, the spherical moving surface can drive the spherical structure of the rotating shaft magnetically connected to it to rotate in the corresponding direction, and then drive the sun visor body to rotate in the corresponding direction.

[0013] Optionally, the driving unit includes:

[0014] A first endless conveyor belt and a second endless conveyor belt are arranged perpendicular to each other, and the first endless conveyor belt and the second endless conveyor belt are respectively magnetically connected to the spherical structure of the rotating shaft;

[0015] a first driving motor, configured to drive the first endless conveyor belt to output a first driving force;

[0016] The second driving motor is used to drive the second endless conveyor belt to output a second driving force, wherein the first driving force and the second driving force are both driving forces in the target direction.

[0017] In an embodiment of the present application, the driving part includes a first annular conveyor belt and a second annular conveyor belt arranged perpendicular to each other, a first drive motor and a second drive motor, and the first annular conveyor belt and the second annular conveyor belt are respectively magnetically connected to the spherical structure of the rotating shaft. Then, as long as the first drive motor drives the first annular conveyor belt to output the first driving force, or the second drive motor drives the second annular conveyor belt to output the second driving force, the first driving force and the second driving force can be considered as driving forces in different directions, which can drive the spherical structure of the rotating shaft magnetically connected thereto to rotate in the corresponding direction, and then drive the sun visor body to rotate in the corresponding direction.

[0018] In a second aspect, an embodiment of the present application provides a control method for a sun visor assembly, which is applied to the sun visor assembly according to any one of the first aspects of the claim, the method comprising:

[0019] During the vehicle driving process, obtaining a first light intensity at a target location;

[0020] If the first light intensity is greater than a set threshold, a sun visor opening instruction is sent to the driving unit, and the sun visor opening instruction is used to instruct the driving unit to output a driving force so that the sun visor body blocks external light from the target direction.

[0021] In an embodiment of the present application, during the driving of the vehicle, the first light intensity of the target direction can be obtained. If the first light intensity is high, it can be considered that it may have an adverse effect on the user's driving of the vehicle. At this time, a sun visor opening instruction can be sent to the driving unit. The sun visor opening instruction is used to instruct the driving unit to output a driving force, thereby driving the sun visor body to rotate to block the external light from the target direction, which not only meets the sunshade requirements of the target direction, but also improves driving safety.

[0022] Optionally, the target orientation is a forward orientation and a side orientation, the first light intensity includes a forward light intensity corresponding to the forward orientation and a side light intensity corresponding to the side orientation, and if the first light intensity is greater than a set threshold, sending a sun visor opening instruction to the driving unit includes:

[0023] If the forward light intensity is greater than the side light intensity and the forward light intensity is greater than the set threshold, a sun visor front opening instruction is sent to the driving unit so that the sun visor body blocks external light from the forward direction.

[0024] In an embodiment of the present application, the forward light intensity and the side light intensity can be obtained at the same time. When it is determined that the forward light intensity is greater than the set threshold and greater than the side light intensity, it can be considered that the external light from the forward direction has a greater adverse effect on the user. At this time, a sun visor front opening instruction can be sent to the driving unit. The sun visor front opening instruction is used to instruct the driving unit to output a driving force in the corresponding direction, thereby driving the sun visor body to rotate in a specific direction to block the external light from the forward direction, which not only meets the sunshade needs in the forward direction, but also improves driving safety.

[0025] Optionally, the method further includes:

[0026] If the forward light intensity is less than the side light intensity and the side light intensity is greater than the set threshold, a sun visor side opening instruction is sent to the driving unit to enable the sun visor to block external light from the side direction.

[0027] In an embodiment of the present application, the forward light intensity and the side light intensity can be obtained at the same time. When it is determined that the side light intensity is greater than the set threshold and greater than the forward light intensity, it can be considered that the external light from the side direction has a greater adverse effect on the user. At this time, a side opening instruction of the sun visor can be sent to the driving unit. The side opening instruction of the sun visor is used to instruct the driving unit to output a driving force in the corresponding direction, thereby driving the sun visor body to rotate in a specific direction to block the external light from the side, which not only meets the sunshade requirements in the lateral direction, but also improves driving safety.

[0028] Optionally, if the forward light intensity is greater than the side light intensity and the forward light intensity is greater than the set threshold, sending a sun visor front opening instruction to the driving unit includes:

[0029] If the forward light intensity is greater than the side light intensity and the forward light intensity is greater than the set threshold, determining a first target adjustment mode of the sun visor body, wherein the first target adjustment mode is used to indicate that the sun visor body needs to be horizontally rotated from an initial position toward a side away from the vehicle roof, the initial position being that the sun visor body is parallel to the vehicle roof;

[0030] determining a first target driving direction of the driving unit according to the first target adjustment mode;

[0031] Obtaining and determining a first horizontal rotation angle of the sun visor body when horizontally rotating based on an actual eye position of a target user in the vehicle;

[0032] determining a first target driving duration of the driving unit according to the first horizontal rotation angle;

[0033] The sun visor front opening instruction is sent to the driving unit, where the sun visor front opening instruction carries the first target driving direction and the corresponding first target driving duration.

[0034] In an embodiment of the present application, if the forward light intensity is determined to be greater than a set threshold and greater than the side light intensity, a first target adjustment mode corresponding to the sun visor body can be determined, i.e., the sun visor body needs to be horizontally rotated from its initial position (parallel to the vehicle roof) toward a side away from the vehicle roof. Accordingly, a first target driving direction of the driving unit can be further determined based on the first target adjustment mode. Furthermore, the specific angle of horizontal rotation required for the sun visor body when facing forward can be determined based on the actual eye position of the user in the vehicle. Since the sun visor body generally rotates horizontally at a constant speed, a first target driving duration of the driving unit can be determined based on the specific angle of horizontal rotation required for the sun visor body. Based on this, a sun visor front-opening command is sent to the driving unit, which carries the first target driving direction and the corresponding first target driving duration. The driving unit then outputs a driving force based on the first target driving direction and the first target driving duration, causing the sun visor body to adjust according to the first target adjustment mode, thereby more accurately shielding the current user from external light from the forward direction.

[0035] Optionally, if the forward light intensity is less than the side light intensity, and the side light intensity is greater than the set threshold, sending a sun visor side opening instruction to the driving unit includes:

[0036] If the forward light intensity is less than the side light intensity, and the side light intensity is greater than the set threshold, a second target adjustment mode of the sun visor body is determined, the second target adjustment mode including a vertical rotation adjustment mode and a horizontal rotation adjustment mode, the vertical rotation adjustment mode is used to instruct the sun visor body to vertically rotate from an initial position toward a side close to the vehicle window; the horizontal rotation adjustment mode is used to instruct the sun visor body to continue to horizontally rotate toward a side away from the vehicle window after the vertical rotation is completed, the initial position being that the sun visor body is parallel to and close to the vehicle roof;

[0037] determining a second target driving direction and a second target driving duration of the driving unit according to the vertical rotation adjustment mode;

[0038] determining a third target driving direction of the driving unit according to the horizontal rotation adjustment mode;

[0039] Obtaining and determining a second horizontal rotation angle of the sun visor body when horizontally rotating based on an actual eye position of a target user in the vehicle;

[0040] determining, according to the second horizontal rotation angle, a third target driving time for the driving unit to drive the sun visor body to horizontally rotate;

[0041] The sun visor side opening instruction is sent to the driving unit, and the sun visor side opening instruction carries the second target driving direction and the corresponding second target driving duration, and the third target driving direction and the corresponding third target driving duration.

[0042] In an embodiment of the present application, if the side light intensity is determined to be greater than a set threshold and greater than the front light intensity, it can be determined that the sun visor body needs to undergo two adjustment processes: a vertical rotation adjustment mode and a horizontal rotation adjustment mode. The vertical rotation adjustment mode requires the sun visor body to be vertically rotated from its initial position (parallel and close to the vehicle roof) toward the side closer to the vehicle window, while the horizontal rotation adjustment mode requires the sun visor body to continue to be horizontally rotated away from the vehicle window after completing the vertical rotation. Based on this, a second target driving direction and a second target driving duration of the driving unit can be determined based on the vertical rotation adjustment mode. Simultaneously, a third target driving direction of the driving unit can be determined based on the horizontal rotation adjustment mode, and the specific angle to which the sun visor body needs to be horizontally rotated when facing sideways can be determined based on the actual eye position of the user in the vehicle. Since the sun visor body typically rotates horizontally at a constant speed, the third target driving duration of the driving unit can be determined based on the specific angle to which the sun visor body needs to be horizontally rotated. Finally, by sending a sun visor side opening instruction to the driving unit, the sun visor side opening instruction carries the above-mentioned second target driving direction and the corresponding second target driving duration, as well as the third target driving direction and the corresponding third target driving duration, so that the driving unit can output driving force based on the corresponding driving direction and the corresponding driving duration in sequence to drive the sun visor body to adjust based on the second target adjustment mode and the third target adjustment mode, thereby more accurately blocking external light from the side direction for the current user without affecting the user's line of sight.

[0043] Optionally, the method further includes:

[0044] Obtaining a second light intensity at the target location at intervals of a preset duration;

[0045] If the second light intensity is less than the set threshold, a sun visor closing instruction is sent to the driving unit to reset the sun visor body to an initial position.

[0046] In an embodiment of the present application, the second light intensity of the target direction can be obtained again at intervals of a preset time. If the second light intensity is less than a set threshold, it can be considered that the external light from the target direction has little adverse effect on the user's driving. At this time, a sun visor closing command can be sent to the drive unit so that the sun visor body can be restored to its initial position.

[0047] In a third aspect, an embodiment of the present application provides a vehicle, comprising the sun visor assembly described in any one of the first aspects.

[0048] It should be understood that the third aspect of the embodiment of the present application is consistent with the technical solution of the first aspect of the embodiment of the present application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation methods are similar and will not be repeated.

[0060] In order to better understand the technical solutions of this specification, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] It should be clear that the embodiments described are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this specification.

[0062] The terms used in the examples of this application are for the purpose of describing specific embodiments only and are not intended to limit this specification. The singular forms "a," "an," "the," and "the" used in the examples of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0063] Currently, if a user feels direct sunlight in their eyes while driving, they can only manually adjust the sun visor to block the direct sunlight. However, this method has the following two problems: First, the user often adjusts the sun visor only after they notice the sunlight directly in their eyes, which has a lag in the timing of adjustment and can easily lead to safety accidents. Second, when manually adjusting the sun visor, the user's eyes are diverted to the sun visor, ignoring possible dangers around the vehicle, which can easily lead to safety accidents.

[0064] In view of this, an embodiment of the present application provides a sun visor assembly, in which a driving force in a specific direction is output by a driving unit, which can directly drive the rotating shaft connected to the driving unit to rotate, and then indirectly drive the sun visor body connected to the rotating shaft to rotate, that is, the rotation angle of the sun visor body can be automatically and timely adjusted, which can not only meet the needs of front shading and side shading, but also improve driving safety.

[0065] The technical solutions provided in the embodiments of the present application are introduced below with reference to the accompanying drawings.

[0066] See Figure 1 , is a structural diagram of a sun visor assembly provided in an embodiment of the present application. Figure 1 As shown, the sun visor assembly 10 includes:

[0067] Sun visor body 101;

[0068] The driving unit 102 is used to output a driving force in a target direction;

[0069] The rotating shaft 103 has one end fixedly connected to the sun visor body 101 , and the other end of the rotating shaft 103 is magnetically connected to the driving unit. The other end of the rotating shaft 103 is a spherical structure 1031 .

[0070] In the embodiment of the present application, the sun visor assembly 10 includes a driving part 102, a rotating shaft 103 and a sun visor body 101 connected in sequence. As long as the driving part 102 outputs a driving force in the target direction, it can drive the spherical structure 1031 end of the rotating shaft to rotate in the corresponding direction, and then drive the sun visor body 101 fixedly connected to the other end of the rotating shaft 103 to rotate accordingly, thereby realizing automatic and timely adjustment of the rotation angle of the sun visor body 101, which not only meets the needs of front shading and side shading, but also improves driving safety.

[0071] It is worth noting that the driving unit 102 is arranged in the vehicle body, and the rotation direction of the sun visor body 101 is the same as the rotation direction of the rotating shaft 103, and the rotation direction of the rotating shaft 103 can be configured to be the same as the direction of the driving force output by the driving unit 102, or it can be configured to be opposite to the direction of the driving force output by the driving unit 102. This application does not impose any special restrictions on this.

[0072] The specific implementation structure of the driving unit 102 will be described in detail below with reference to the accompanying drawings.

[0073] Based on the description of the function of the driver 102, please refer to Figure 2 The driving unit 102 provided in the embodiment of the present application can be implemented by the following subdivided components, which may include:

[0074] The spherical motion surface 1021 is connected to the spherical structure 1031 of the rotating shaft 103 by magnetic attraction;

[0075] The driving motor 1022 is used to drive the spherical motion surface 1021 to output a driving force in a target direction.

[0076] In the embodiment of the present application, the drive unit 102 includes a spherical moving surface 1021 and a drive motor 1022. The spherical moving surface 1021 is magnetically connected to the end of the spherical structure 1031 of the rotating shaft 103. Therefore, as long as the drive motor 1022 drives the spherical moving surface 1021 to output a driving force in a target direction, the spherical moving surface 1021 can drive the spherical structure 1031 of the rotating shaft 103 to which it is magnetically connected to rotate in the corresponding direction, thereby driving the sun visor body 101 to rotate in the corresponding direction. It should be understood that the spherical moving surface supports outputting a driving force in any direction, for example, a driving force parallel to the ground or a driving force perpendicular to the ground.

[0077] Based on the description of the function of the driver 102, please refer to Figure 3 The driving unit 102 provided in the embodiment of the present application can be implemented by the following subdivided components, which may include:

[0078] A first endless conveyor belt 1023 and a second endless conveyor belt 1024 are arranged perpendicular to each other, and the first endless conveyor belt 1023 and the second endless conveyor belt 1024 are respectively magnetically connected to the spherical structure 1031 of the rotating shaft 103;

[0079] A first driving motor is used to drive the first endless conveyor belt to output a first driving force;

[0080] The second driving motor is used to drive the second endless conveyor belt to output a second driving force, wherein the first driving force and the second driving force are both driving forces in a target direction.

[0081] In an embodiment of the present application, the driving unit 102 includes a first annular conveyor belt 1023 and a second annular conveyor belt 1024 which are arranged perpendicular to each other, a first driving motor (not shown in the figure) and a second driving motor (not shown in the figure). The first annular conveyor belt 1023 and the second annular conveyor belt 1024 are respectively magnetically connected to the spherical structure 1031 of the rotating shaft 103. As long as the first driving motor drives the first annular conveyor belt 1023 to output the first driving force, or the second driving motor drives the second annular conveyor belt 1024 to output the second driving force, the first driving force and the second driving force can be considered as driving forces in different directions, which can drive the spherical structure 1031 of the rotating shaft 103 magnetically connected thereto to rotate in the corresponding direction, and then drive the sun visor body 101 to rotate in the corresponding direction.

[0082] The control method of the sun visor assembly 10 in the above embodiment is described below.

[0083] See Figure 4 , is a flow chart of a control method for a sun visor assembly provided in an embodiment of the present application. The method can be applied to a controller in a vehicle. The flow of the method is described as follows:

[0084] Step 201: While the vehicle is traveling, obtain a first light intensity at a target location.

[0085] In an embodiment of the present application, a light intensity sensor can be installed at the target position in the vehicle, and the first light intensity of the target position can be detected by the light intensity sensor. The target position here can be the forward position (i.e., the front windshield) and / or the lateral position (i.e., the window) inside the vehicle.

[0086] Step 202: If the first light intensity is greater than a set threshold, a sun visor opening instruction is sent to the driving unit, where the sun visor opening instruction is used to instruct the driving unit to output a driving force so that the sun visor body blocks external light from the target direction.

[0087] In an embodiment of the present application, if the first light intensity detected by the light sensor installed at the target position is greater than a set threshold, it can be considered that the current light intensity is high, which may have an adverse effect on the user's driving. At this time, a sun visor opening instruction can be sent to the driving unit. The sun visor opening instruction is used to control the driving unit to output a driving force, thereby driving the sun visor body to rotate to block the external light from the target position, which not only meets the sunshade requirements of the target position, but also improves driving safety.

[0088] Since the target direction may be the front direction or the side direction, the control process for realizing the two scenarios of front shading and side shading is described in detail below.

[0089] Scenario 1: Frontal shading.

[0090] See Figure 5 , which is a flow chart of a front shading control method provided in an embodiment of the present application. Step 202 can be specifically implemented by executing sub-step 301:

[0091] Step 301: If the forward light intensity is greater than the side light intensity and the forward light intensity is greater than a set threshold, a sun visor front opening instruction is sent to the driving unit so that the sun visor body blocks external light from the forward direction.

[0092] In an embodiment of the present application, light intensity sensors can be installed in both the forward and side directions of the vehicle interior to simultaneously obtain the forward light intensity corresponding to the forward direction and the side light intensity corresponding to the side direction, and compare the forward light intensity with the side light intensity. If it is determined that the forward light intensity is greater than the side light intensity, the forward light intensity is then compared with a set threshold. If it is determined that the forward light intensity is also greater than the set threshold, that is, if it is determined that the forward light intensity is greater than the set threshold and greater than the side light intensity, it can be considered that the external light from the forward direction has a greater adverse effect on the user. At this time, a sun visor front opening instruction can be sent to the drive unit. The sun visor front opening instruction is used to instruct the drive unit to output a driving force in a corresponding direction, thereby driving the sun visor body to rotate in a specific direction to block the external light from the forward direction, thereby meeting the sunshade requirement in the forward direction and improving driving safety.

[0093] See Figure 6 , is a flow chart of a method for sending a sun visor front opening instruction to a driving unit according to an embodiment of the present application. Step 301 can be implemented by executing sub-steps 3011 to 3015:

[0094] Step 3011: If the forward light intensity is greater than the side light intensity, and the forward light intensity is greater than a set threshold, a first target adjustment mode of the sun visor body is determined.

[0095] In an embodiment of the present application, when the forward light intensity is greater than the lateral light intensity, and the forward light intensity is greater than the set threshold, the control strategy at this time is to give priority to meeting the user's front sunshade needs, then it can be determined that the sun visor body should be in the first target adjustment mode, that is, the sun visor body needs to be rotated horizontally from the initial position to the side away from the roof (that is, rotated around an axis parallel to the ground). Here, the initial position of the sun visor can be considered to be parallel and close to the roof.

[0096] Step 3012: Determine a first target driving direction of the driving unit according to the first target adjustment mode.

[0097] In this embodiment of the present application, since a correspondence between the sun visor adjustment mode and the driving direction of the driving unit is pre-stored, the first target driving direction of the driving unit corresponding to the first target adjustment mode of the sun visor body can be determined based on this correspondence. In other words, as long as the driving unit outputs driving force based on the first target driving direction, the sun visor body can be adjusted based on the first target adjustment mode.

[0098] Step 3013: Obtain and determine a first horizontal rotation angle of the sun visor body when it rotates horizontally based on the actual eye position of the target user in the vehicle.

[0099] In the embodiments of the present application, different users may have different heights when driving the same vehicle, resulting in different eye positions within the vehicle. To ensure that the sun visor body blocks external light from the forward direction, different eye positions require corresponding horizontal rotation angles of the sun visor body. Therefore, a radar sensor can be installed inside the vehicle to detect the head posture of the target user and, based on the head posture, estimate the target user's actual eye position. Because a pre-stored correspondence between the user's eye position during frontal sun shading and the horizontal rotation angle of the sun visor body is stored, the first horizontal rotation angle of the sun visor body during frontal sun shading corresponding to the target user's actual eye position can be determined based on this correspondence.

[0100] Step 3014: Determine a first target driving duration of the driving unit according to the first horizontal rotation angle.

[0101] In the embodiment of the present application, since the rotation of the sun visor body is driven by the drive unit, that is, as long as the drive unit remains in the driving state, the sun visor body will continue to rotate. Therefore, based on the pre-stored correspondence between the horizontal rotation angle of the sun visor body and the driving duration of the drive unit, a first target driving duration of the drive unit corresponding to the sun visor body needing to rotate to a first horizontal rotation angle can be determined.

[0102] Step 3015: Send a sun visor front opening instruction to the driving unit.

[0103] In an embodiment of the present application, if one wants the sun visor body to meet the user's frontal sun shading needs, a sun visor front opening instruction can be sent to the driving unit. The sun visor front opening instruction carries the first target driving direction determined in step 3012 and the first target driving duration determined in step 3014, so that the driving unit can output driving force based on the above-mentioned first target driving direction and first target driving duration to drive the sun visor body to adjust based on the first target adjustment mode, thereby more accurately blocking external light from the forward direction for the current user.

[0104] Scenario 2: Side sunshade.

[0105] See Figure 7 , which is a flow chart of a side shading control method provided in an embodiment of the present application. Step 202 can be implemented by executing sub-step 401:

[0106] Step 401: If the forward light intensity is less than the side light intensity, and the side light intensity is greater than a set threshold, a sun visor side opening instruction is sent to the driving unit to enable the sun visor to block external light from the side direction.

[0107] In the embodiment of the present application, light intensity sensors can be installed in both the forward and side directions of the vehicle to simultaneously obtain the forward light intensity corresponding to the forward direction and the side light intensity corresponding to the side direction, and compare the forward light intensity with the side light intensity. If it is determined that the side light intensity is greater than the forward light intensity, the side light intensity is then compared with a set threshold. If it is determined that the side light intensity is also greater than the set threshold, that is, if it is determined that the side light intensity is greater than the set threshold and greater than the forward light intensity, it can be considered that the external light from the side direction has a greater adverse effect on the user. At this time, a sun visor side opening instruction can be sent to the drive unit. The sun visor side opening instruction is used to instruct the drive unit to output a driving force in a corresponding direction, thereby driving the sun visor body to rotate in a specific direction to block the external light from the side direction, thereby meeting the sunshade requirements in the side direction and improving driving safety.

[0108] See Figure 8 , is a flow chart of a method for sending a sun visor side opening instruction to a driving unit according to an embodiment of the present application. Step 401 can be implemented by executing sub-steps 4011 to 4015:

[0109] Step 4011: If the forward light intensity is less than the side light intensity, and the side light intensity is greater than a set threshold, determine a second target adjustment mode of the sun visor body.

[0110] In an embodiment of the present application, when the side light intensity is greater than the forward light intensity and the side light intensity is greater than a set threshold, the control strategy at this time is to prioritize meeting the user's side sunshade needs. In this case, it can be determined that the sun visor body should be in a second target adjustment mode. This second target adjustment mode includes a vertical rotation adjustment mode and a horizontal rotation adjustment mode, which are executed sequentially. The vertical rotation adjustment mode requires the sun visor body to be vertically rotated from an initial position toward the side closer to the vehicle window (i.e., rotated about an axis perpendicular to the ground). Here, the initial position of the sun visor body can be considered to be parallel and close to the vehicle roof. The horizontal rotation adjustment mode requires the sun visor body to continue to rotate horizontally toward the side away from the vehicle window after the vertical rotation is completed. It should be understood that the reason for executing the vertical rotation adjustment mode first is to avoid obstructing the user's line of sight during the process of the sun visor body rotating to the side.

[0111] Step 4012: Determine a second target driving direction and a second target driving duration of the driving unit according to the vertical rotation adjustment mode.

[0112] In an embodiment of the present application, the sun visor body rotates vertically from an initial position to a target position close to the vehicle window side, and the required vertical rotation angle and rotation direction are fixed. Therefore, as long as it is determined that the sun visor body needs to execute a vertical rotation adjustment mode, the second target driving direction and the second target driving duration of the driving part corresponding to the vertical rotation adjustment mode can be directly determined.

[0113] Step 4013: Determine a third target driving direction of the driving unit according to the horizontal rotation adjustment mode.

[0114] In this embodiment of the present application, since a correspondence between the horizontal rotation adjustment mode of the sun visor and the driving direction of the driving unit is pre-stored, the third target driving direction of the driving unit corresponding to the horizontal rotation adjustment mode of the sun visor body can be determined based on this correspondence. In other words, as long as the driving unit outputs a driving force based on the third target driving direction, the visor body can be adjusted in the sideways direction based on the horizontal rotation adjustment mode.

[0115] Step 4014: Obtain and determine a second horizontal rotation angle of the sun visor body when it rotates horizontally based on the actual eye position of the target user in the vehicle.

[0116] In the embodiments of the present application, different users may have different heights when driving the same vehicle, resulting in different eye positions within the vehicle. To ensure that the sun visor body can block external light from the side, different eye positions require corresponding horizontal rotation angles of the sun visor body. Therefore, a radar sensor can be installed inside the vehicle to detect the head posture of the target user and, based on the head posture, estimate the target user's actual eye position. Because a pre-stored correspondence between the user's eye position during side shading and the horizontal rotation angle of the sun visor body is stored, the second horizontal rotation angle of the sun visor body during side shading corresponding to the target user's actual eye position can be determined based on this correspondence.

[0117] Step 4015: Determine a third target driving time for the driving unit to drive the sun visor body to rotate horizontally according to the second horizontal rotation angle.

[0118] In the embodiment of the present application, since the rotation of the sun visor body is driven by the drive unit, that is, as long as the drive unit remains in the driving state, the sun visor body will continue to rotate. Therefore, based on the pre-stored correspondence between the horizontal rotation angle of the sun visor body and the driving duration of the drive unit, a third target driving duration of the drive unit corresponding to the second horizontal rotation angle of the sun visor body can be determined.

[0119] Step 4016: Send a sun visor side opening instruction to the driving unit.

[0120] In an embodiment of the present application, if the sun visor body is to meet the user's side shading needs, a sun visor side opening instruction can be sent to the driving unit. The sun visor side opening instruction carries the second target driving direction and the second target driving duration determined in step 4012, as well as the third target driving direction determined in step 4013, and the third target driving duration corresponding to the third target driving direction determined in step 4015, so that the driving unit can output driving force based on the above-mentioned second target driving direction and the corresponding second target driving duration, the above-mentioned third target driving direction and the corresponding third target driving duration in sequence, so as to drive the sun visor body to adjust based on the second target adjustment mode, thereby more accurately blocking external light from the side direction for the current user.

[0121] It is worth noting that when the sun visor body is shading the front, if the direction of the light intensity with greater intensity changes, that is, the light intensity in the forward direction is greater than the light intensity in the side direction, and the light intensity in the forward direction is greater than the set threshold, and the light intensity in the side direction is greater than the light intensity in the forward direction, and the light intensity in the side direction is greater than the set threshold, then if side shading is desired, the drive unit can be controlled to output a driving force in a direction opposite to the first target driving direction based on the first target driving duration, thereby controlling the sun visor body to return to its initial position. The sun visor body is then adjusted based on the second target adjustment mode, thereby avoiding interference with the user's vision caused by the rotation of the sun visor body during the switch from front shading to side shading.

[0122] When the sun visor body is shading the side, if the direction with greater light intensity changes, that is, the light intensity in the side direction is greater than the light intensity in the front direction, and the light intensity in the side direction is greater than the set threshold, it changes to the light intensity in the front direction is greater than the light intensity in the side direction, and the light intensity in the front direction is greater than the set threshold, if you want to achieve front shading at this time, you can first control the driving part to output a driving force in the opposite direction of the third target driving direction based on the third target driving duration, and then control the driving part to output a driving force in the opposite direction of the second target driving direction based on the second target driving duration, so that the sun visor body returns to its initial position, and then adjust the sun visor body based on the first target adjustment mode, so as to avoid interference with the user's vision caused by the rotation of the sun visor body during the process of switching from side shading to front shading.

[0123] In some embodiments, considering that the light intensity in the target direction may gradually decrease over time, in an embodiment of the present application, when the light intensity in the target direction is detected to be low, the sun visor body can be restored to its initial position and no longer blocks external light from the target direction.

[0124] See Figure 9 , is a flow chart of a control method for a sun visor assembly provided in an embodiment of the present application, the flow of the method comprising:

[0125] Step 501: Obtain a second light intensity at a target location at intervals of a preset time length.

[0126] Step 502: If the second light intensity is less than the set threshold, a sun visor closing instruction is sent to the driving unit to reset the sun visor body to the initial position.

[0127] In the embodiment of the present application, the light intensity in the target direction, for example, a second light intensity, is re-acquired at predetermined intervals. If the second light intensity is less than a predetermined threshold, it can be determined that the external light from the target direction has a minimal adverse effect on the user's driving. In this case, a sun visor closing instruction can be sent to the drive unit to restore the sun visor body to its initial position.

[0128] It is worth noting that in the above embodiment, the sun visor body can be controlled to return to the initial position when the second light intensity is detected to be less than the set threshold for the first time; or the sun visor body can be controlled to return to the initial position when the second light intensity is detected to be less than the set threshold for multiple times. This application does not impose any special restrictions on this.

[0129] See Figure 10 Based on the same inventive concept, the embodiment of the present application provides a vehicle 60, which includes Figure 1-Figure 3 In the sun visor assembly 10 shown, the vehicle 60 can be a pure electric vehicle, an extended-range vehicle, a plug-in hybrid vehicle, or a fuel vehicle, and this application does not impose any special restrictions on this.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this specification should be included in the scope of protection of this specification.
