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, when a user feels the sun shining directly into his eyes while driving a vehicle, the user can only manually adjust the angle of the sun visor to block the direct sunlight. However, the above method has the following two problems: first, the user often manually adjusts the sun visor only after he feels the sun shining directly into his eyes, and there is a lag in the timing of adjustment, which makes it easy to cause safety accidents; second, when the user manually adjusts the sun visor, the user's line of sight shifts to the sun visor, and the user ignores the possible dangers around the vehicle, which makes it easy to cause 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 realize automatic and timely adjustment of the rotation angle of the sun visor body, thereby meeting the needs of front 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 outwards;

[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 which are connected in sequence. As long as the driving part outputs a driving force in a target direction, the spherical structure end of the rotating shaft can be driven to rotate in a corresponding direction, thereby driving 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 rotation axis by magnetic attraction;

[0011] A driving motor is used to drive the spherical motion surface to output a 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, and the spherical moving surface is magnetically connected to the spherical structure end of the rotating shaft. Therefore, 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 annular conveyor belt and a second annular conveyor belt are arranged perpendicular to each other, and the first annular conveyor belt and the second annular conveyor belt are respectively magnetically connected to the spherical structure of the rotating shaft;

[0015] A first driving motor, used for driving 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 circular conveyor belt and a second circular conveyor belt arranged perpendicular to each other, a first driving motor and a second driving motor, and the first circular conveyor belt and the second circular conveyor belt are respectively magnetically connected to the spherical structure of the rotating shaft. Therefore, as long as the first driving motor drives the first circular conveyor belt to output the first driving force, or the second driving motor drives the second circular 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 claims, and the method comprises:

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

[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, a first light intensity at 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 command can be sent to the driving unit. The sun visor opening command 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 shading requirements of the target direction, but also improves driving safety.

[0022] Optionally, the target orientation is a forward orientation and a lateral orientation, the first light intensity includes a forward light intensity corresponding to the forward orientation and a lateral light intensity corresponding to the lateral 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 lateral 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, and when it is determined that the forward light intensity is greater than a 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, 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 so that the sun visor blocks 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, and 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 shading needs of the lateral direction, but also improves driving safety.

[0028] Optionally, if the forward light intensity is greater than the lateral 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 lateral light intensity, and the forward light intensity is greater than the set threshold, a first target adjustment mode of the sun visor body is determined, wherein the first target adjustment mode is used to indicate that the sun visor body needs to be horizontally rotated from an initial position to a side away from the roof, and the initial position is that the sun visor body is parallel to the roof;

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

[0031] Acquiring and determining a first horizontal rotation angle of the sun visor body when horizontally rotating according to 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, wherein the sun visor front opening instruction carries the first target driving direction and the corresponding first target driving duration.

[0034] In the embodiment of the present application, if it is determined that the forward illumination intensity is greater than the set threshold value and greater than the lateral illumination intensity, then the first target adjustment mode corresponding to the sun visor body can be determined, that is, the sun visor body needs to be horizontally rotated from the initial position (parallel to the roof) to the side away from the roof, and accordingly, the first target driving direction of the driving unit can be further determined according to the first target adjustment mode; at the same time, the specific angle at which the sun visor body needs to be horizontally rotated when facing the front can be determined according to the actual eye position of the user in the vehicle. Since the sun visor body is usually at a uniform speed when rotating horizontally, the first target driving duration of the driving unit can be determined according to the specific angle at which the sun visor body needs to be horizontally rotated. On this basis, by sending a sun visor front opening instruction to the driving unit, the sun visor front opening instruction carries the first target driving direction and the corresponding first target driving duration, so that the driving unit can output a driving force based on the first target driving direction and the first target driving duration to drive the sun visor body to adjust based on the first target adjustment mode, thereby more accurately shielding the external light from the forward direction for the current user.

[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 illumination intensity is less than the lateral illumination intensity, and the lateral illumination intensity is greater than the set threshold, a second target adjustment mode of the sun visor body is determined, the second target adjustment mode comprising a vertical rotation adjustment mode and a horizontal rotation adjustment mode, the vertical rotation adjustment mode being 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 being used to instruct the sun visor body to continue to horizontally rotate 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] Acquiring and determining a second horizontal rotation angle of the sun visor body when the sun visor body rotates horizontally according to the actual eye position of the target user in the vehicle;

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

[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 the embodiment of the present application, if it is determined that the lateral illumination intensity is greater than the set threshold value and greater than the forward illumination intensity, then it can be determined that the sun visor body needs to go through two adjustment processes, namely, a vertical rotation adjustment mode and a horizontal rotation adjustment mode, wherein the vertical rotation adjustment mode is to vertically rotate the sun visor body from the initial position (parallel and close to the roof) to the side close to the window, and the horizontal rotation adjustment mode is to continue to horizontally rotate the sun visor body away from the window after the vertical rotation is completed. On this basis, firstly, the second target driving direction and the second target driving duration of the driving unit can be determined according to the vertical rotation adjustment mode, and at the same time, the third target driving direction of the driving unit can be determined according to the horizontal rotation adjustment mode, and the specific angle of horizontal rotation required for the above-mentioned sun visor body when it is on the side can be determined according to the actual eye position of the user in the vehicle. Since the sun visor body is usually at a uniform speed when rotating horizontally, the third target driving duration of the driving unit can be determined according to the specific angle of horizontal rotation required for the sun visor body. 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, so as to drive the sun visor body to adjust based on the second target adjustment mode and the third target adjustment mode, so as to more accurately block the 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] Acquire a second illumination intensity of the target position at intervals of a preset time length;

[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 in the target direction can be obtained again at a preset time interval. 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 a sun visor assembly as 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 here.

[0060] In order to better understand the technical solution 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 described embodiments 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 creative work are within the scope of protection of this specification.

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

[0063] Currently, when a user feels the sun shining directly into his eyes while driving a vehicle, the user can only manually adjust the angle of the sun visor to block the direct sunlight. However, the above method has the following two problems: first, the user often adjusts the sun visor only after he feels the sun shining directly into his eyes, and there is a lag in the timing of adjustment, which makes it easy to cause safety accidents; second, when the user manually adjusts the sun visor, the user's line of sight shifts to the sun visor, and the user ignores the possible dangers around the vehicle, which makes it easy to cause 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 a rotating shaft connected to the driving unit to rotate, and then indirectly drive a 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 meet the needs of front shading and side shading, and can improve driving safety.

[0065] The technical solution provided by the embodiments of the present application is introduced below in conjunction with the accompanying drawings.

[0066] See also Figure 1 , is a schematic diagram of the structure 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] A driving unit 102, used for outputting a driving force in a target direction outward;

[0069] The rotating shaft 103 , wherein one end of the rotating shaft 103 is fixedly connected to the sun visor body 101 , and the other end of the rotating shaft 103 is magnetically connected to the driving unit, and 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 unit 102, a rotating shaft 103 and a sun visor body 101 which are connected in sequence. As long as the driving unit 102 outputs a driving force in a target direction, it can drive the end of the spherical structure 1031 of the rotating shaft to rotate in a corresponding direction, thereby driving 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, and can also be configured to be opposite to the direction of the driving force output by the driving unit 102. The present application does not impose any special restrictions on this.

[0072] The specific implementation structure of the driving unit 102 is described in detail below in conjunction with the accompanying drawings of the specification.

[0073] Based on the description of the function of the driving unit 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 can specifically 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 driving part 102 includes a spherical motion surface 1021 and a driving motor 1022. The spherical motion surface 1021 is magnetically connected to the end of the spherical structure 1031 of the rotating shaft 103. As long as the driving motor 1022 drives the spherical motion surface 1021 to output a driving force in a target direction, the spherical motion surface 1021 can drive the spherical structure 1031 of the rotating shaft 103 magnetically connected thereto 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 motion 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 driving unit 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 can specifically include:

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

[0079] A first driving motor, used for driving 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 the embodiment of the present application, the driving unit 102 includes a first circular conveyor belt 1023 and a second circular 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 circular conveyor belt 1023 and the second circular 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 circular conveyor belt 1023 to output the first driving force, or the second driving motor drives the second circular 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 also Figure 4 , is a flow chart of a control method of 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 chart of the method is as follows:

[0084] Step 201: During vehicle driving, a first light intensity at a target location is obtained.

[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, 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.

[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 and may have an adverse effect on the user's driving. At this time, a sun visor opening command can be sent to the drive unit. The sun visor opening command is used to control the drive 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 shading requirements of the target position, but also improves driving safety.

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

[0089] Scene 1: Frontal shading.

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

[0091] Step 301: If the forward light intensity is greater than the lateral 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 the embodiment of the present application, light intensity sensors can be installed in both the forward and lateral directions of the vehicle, so as to simultaneously obtain the forward light intensity corresponding to the forward direction and the lateral light intensity corresponding to the lateral direction, and compare the forward light intensity with the lateral light intensity. If it is determined that the forward light intensity is greater than the lateral light intensity, the forward light intensity is compared with the set threshold value. If it is determined that the forward light intensity is also greater than the set threshold value, that is, it is determined that the forward light intensity is greater than the set threshold value and greater than the lateral 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 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 demand of the forward direction, but also improves driving safety.

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

[0094] Step 3011: If the forward illumination intensity is greater than the lateral illumination intensity, and the forward illumination 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 frontal shading 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 rotate horizontally from the initial position to the side away from the roof (that is, rotate around an axis parallel to the ground), and the initial position of the sun visor here 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 the embodiment of the present application, since the correspondence between the adjustment mode of the sun visor 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 the above correspondence. In other words, as long as the driving unit outputs the driving force based on the first target driving direction, it can be ensured that the sun visor body is 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 embodiment of the present application, it is considered that when different users drive the same vehicle, the eye positions of different users in the vehicle may be different due to the difference in height of different users. If the sun visor body is to be able to block the external light from the forward direction, different eye positions require different horizontal rotation angles of the sun visor body. Therefore, a radar sensor can be installed inside the vehicle, through which the head posture of the target user can be detected, and then the actual eye position of the target user can be evaluated through the head posture. Since the correspondence between the eye position of the user when front shading and the horizontal rotation angle of the sun visor body is pre-stored, based on the above correspondence, the first horizontal rotation angle of the sun visor body corresponding to the actual eye position of the target user when front shading can be determined.

[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 driving unit, that is, as long as the driving unit remains in the driving state, the sun visor body will continue to rotate. Therefore, the first target driving time of the driving unit corresponding to the sun visor body needing to rotate the first horizontal rotation angle can be determined based on the pre-stored correspondence between the horizontal rotation angle of the sun visor body and the driving time of the driving unit.

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

[0103] In the embodiment of the present application, if the sun visor body is to meet the user's frontal 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 a driving force based on the above-mentioned first target driving direction and the first target driving duration, so as to drive the sun visor body to adjust based on the first target adjustment mode, thereby more accurately blocking the external light from the forward direction for the current user.

[0104] Scenario 2: Side shading.

[0105] See also Figure 7 , 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 a driving unit so that the sun visor blocks external light from the side.

[0107] In the embodiment of the present application, the light intensity sensor can be installed in both the forward direction and the side direction 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 compared with the set threshold value. If it is determined that the side light intensity is also greater than the set threshold value, that is, it is determined that the side light intensity is greater than the set threshold value 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 the corresponding direction, thereby driving the sun visor body to rotate in a specific direction to block the external light from the side direction, which not only meets the sunshade demand of the side direction, but also improves driving safety.

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

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

[0110] In the embodiment of the present application, when the lateral illumination intensity is greater than the forward illumination intensity, and the lateral illumination intensity is greater than the set threshold, the control strategy at this time is to give priority to satisfying the user's side sunshade needs, then it can be determined that the sun visor body should be in the second target adjustment mode, and the second target adjustment mode includes a vertical rotation adjustment mode and a horizontal rotation adjustment mode that are executed in sequence. The vertical rotation adjustment mode requires the sun visor body to be vertically rotated from the initial position to the side close to the window (i.e., rotated around an axis perpendicular to the ground), where the initial position of the sun visor body can be considered to be parallel and close to the roof; the horizontal rotation adjustment mode is that the sun visor body continues to rotate horizontally away from the window after the vertical rotation is completed. It should be understood that the reason why the vertical rotation adjustment mode needs to be executed first is to avoid blocking the user's line of sight during the rotation of the sun visor body 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 the embodiment of the present application, the sun visor body rotates vertically from an initial position to a target position close to the 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 the embodiment of the present application, since the 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 the above correspondence. In other words, as long as the driving unit outputs the driving force based on the third target driving direction, it can be ensured that the sun visor body is adjusted in the side position 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 embodiment of the present application, it is considered that when different users drive the same vehicle, the eye positions of different users in the vehicle may be different due to the difference in height of different users. If the sun visor body is to be able to block the external light from the lateral direction, different eye positions require different horizontal rotation angles of the sun visor body. Therefore, a radar sensor can be installed inside the vehicle, through which the head posture of the target user can be detected, and then the actual eye position of the target user can be evaluated through the head posture. Since the correspondence between the eye position of the user during side shading and the horizontal rotation angle of the sun visor body is pre-stored, based on the above correspondence, the second horizontal rotation angle of the sun visor body during side shading corresponding to the actual eye position of the target user can be determined.

[0117] Step 4015: According to the second horizontal rotation angle, determine a third target driving time length when the driving unit drives the sun visor body to rotate horizontally.

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

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

[0120] In the 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, so as to drive the sun visor body to adjust based on the second target adjustment mode, thereby more accurately blocking the external light from the lateral direction for the current user.

[0121] It is worth noting that when the sun visor body is shading the front, if the direction with greater light intensity changes, that is, the light intensity in the forward direction is greater than the light intensity in the lateral direction, and the light intensity in the forward direction is greater than the set threshold, and the light intensity in the lateral direction is greater than the light intensity in the forward direction, and the light intensity in the lateral direction is greater than the set threshold, if you want to achieve side shading at this time, you can control the drive unit to output a driving force in the opposite direction of the first target driving direction based on the first target driving duration, so as to control the sun visor body to return to the initial position. Then adjust the sun visor body based on the above second 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 front shading to side shading.

[0122] When the sun visor body is shading at 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 unit 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 unit 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 line of sight 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 at the target direction may gradually decrease with the passage of time, in an embodiment of the present application, when the light intensity at 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 also Fig. 9 , is a flow chart of a control method of 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.

[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 of the target direction, for example, the second light intensity, is re-acquired at every preset time interval. If the second light intensity is less than the set threshold, it can be considered that the external light from the target direction has little adverse effect on the user's driving, and at this time, a sun visor closing instruction can be sent to the driving unit so that the sun visor body can be restored to the initial position.

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