[0044] Overview

[0045] As described in the background art, with the rapid development of automotive technology, users' requirements for the riding experience are also getting higher and higher. In order to block light and prevent mosquitoes, etc., traditional vehicles usually install door curtains by means of hooks or bonding, etc., which are easy to damage the surface of the car door, and the sealing performance is not good, making it difficult to effectively block light and prevent mosquitoes. Especially for vehicles with electric double-leaf doors, due to the large size of the car door, it is difficult to meet the requirements for sealing performance. The magnetic door curtain has significant advantages in ventilation, light blocking, privacy protection, mosquito prevention, etc., and the magnetic door curtain is adsorbed in areas such as the door frame by magnets, etc. after being unfolded, and the sealing performance is good, so it is widely used in vehicles.

[0046] Currently, the magnetic door curtain of a vehicle is usually manually controlled by a user. For example, the magnetic door curtain is controlled to be unfolded or folded by means of a button or a pull rope, etc. However, if the magnetic door curtain is in an unfolded state when the car door is opened, it is easy to roll the magnetic door curtain into the mechanical structure of the car door. At the same time, during the folding process of the magnetic door curtain, due to the relatively large magnetic attraction, the door curtain is easily subjected to a large pulling force during the folding process. Therefore, the traditional control method of the magnetic door curtain is extremely likely to cause damage to the magnetic door curtain, thus unable to guarantee the user experience.

[0047] To solve the problem that the traditional method is likely to damage the magnetic curtain during the process of opening the vehicle door, in the technical solution of this application, a magnetic curtain control method, device and vehicle are provided, which are applied to the curtain controller corresponding to the magnetic curtain of the vehicle. The magnetic curtain includes a curtain body and a folding mechanism. A magnetic structure is arranged on the curtain body, and the magnetic structure is used to attract and combine with the door frame of the vehicle door when the curtain body is in the unfolded state. When receiving the opening signal of the target door, this solution identifies the current state of the curtain body. If the current state of the curtain body is the unfolded state, it waits for a predetermined time period and then controls the magnetic force of the magnetic structure to decrease. When the magnetic force of the magnetic structure reaches the first target magnetic force, it controls the folding mechanism to fold the curtain body. The predetermined time period is greater than 0 and less than the predetermined opening time period of the target door. Thus, it can control the curtain body to be desorbed and folded after the vehicle door is opened to a certain extent, greatly reducing the risk of damage to the curtain body caused by the curtain body being involved in the mechanical structure of the target door during the process of opening the vehicle door. At the same time, through desorption, it can avoid damage to the curtain body due to excessive pulling force during the folding process, thereby further reducing the risk of damage to the magnetic curtain and effectively improving the user experience.

[0048] Based on the above inventive concept, the magnetic curtain control method provided by the embodiments of this specification will be described exemplarily below.

[0049] Exemplary Method

[0050] The embodiments of this specification provide a magnetic curtain control method, which is applied to the curtain controller corresponding to the magnetic curtain of the vehicle. The magnetic curtain includes a curtain body and a folding mechanism. A magnetic structure is arranged on the curtain body, and the magnetic structure is used to attract and combine with the door frame of the vehicle door when the curtain body is in the unfolded state.

[0051] Specifically, the vehicle can be a vehicle including an electric door, such as a passenger vehicle or a commercial vehicle, etc. Among them, the electric door can be a double-leaf door or a single-leaf door.

[0052] The magnetic curtain includes a curtain body and a folding mechanism. The folding mechanism is used to fold or release the curtain body. The folding mechanism can include a driving motor and an electric scroll. The driving motor can be used to drive the electric scroll to fold or release the curtain body. Among them, the folding mechanism can be arranged in the inner side frame area of the target door of the vehicle. The target door is the door on which the magnetic curtain is installed. For example, the folding mechanism can be arranged in the frame area at the inner top of the target door. During implementation, the folding mechanism can be installed through mounting brackets and fasteners, etc., without drilling or pasting, which is convenient for the installation and disassembly of the magnetic curtain.

[0053] The curtain body can be made of a composite material that is flexible, environmentally friendly, wear-resistant, waterproof, and has a certain strength and heat and sound insulation performance, such as specially treated fabrics or polymer materials, etc. A predetermined pattern can also be printed on the curtain body. At the same time, the material can be treated against aging to have excellent anti-aging performance and reduce the risk of fading or deformation of the magnetic curtain during use.

[0054] In addition, a magnetic attraction structure can be embedded at the edge of the curtain body. The magnetic attraction structures can be evenly arranged at a predetermined interval. When the curtain body is in the unfolded state, the magnetic attraction structures can be adsorbed on the door frame of the target vehicle door through magnetic attraction to form a relatively sealed barrier. Among them, the size and shape of the curtain body can be determined according to the size and shape of the target vehicle door, so that the curtain body fits closely with the target vehicle door in the unfolded state to achieve the best sealing effect.

[0055] In implementation, a magnetic receiving structure can be set on the door frame of the target vehicle door. The position of the magnetic receiving structure corresponds to the position of the magnetic attraction structure when the curtain body is in the unfolded state, so that the curtain body can be effectively attracted to the door frame when in the unfolded state, ensuring the flatness of the curtain body, and thus being able to form a seamless seal to effectively isolate external dust, noise, insects, etc.

[0056] Optionally, the magnetic attraction structure uses a magnetic material with an anti-magnetic decay coefficient greater than a predetermined value, and the magnetic attraction structure is treated against rust and wear. Thus, during the long-term and frequent adsorption and desorption process of the magnetic curtain, the stability of the magnetic force performance of the magnetic attraction structure can be ensured, so that the adsorption times of the magnetic attraction structure reach the target times, and the significant decrease in the magnetic force of the magnetic attraction structure caused by factors such as oxidation and wear is avoided.

[0057] Optionally, the curtain body uses a composite fiber fabric with a strength greater than or equal to the target strength and a toughness greater than or equal to the target toughness, and the composite fiber fabric is treated against weathering. Thus, during the use of the magnetic curtain, the anti-ultraviolet performance and anti-aging performance of the curtain body can be ensured, and it can be repeatedly used in the extreme temperature environment within the tolerable temperature range without catalysis or degradation.

[0058] Optionally, a protective coating is applied on the curtain body, so that the curtain body has good wear resistance and scratch resistance. The number of wear-resistant times of the protective coating is greater than or equal to the target number of wear-resistant times. Thus, during the use of the magnetic curtain, the mechanical damage of the curtain body caused by scratching and collision with sharp objects can be effectively reduced.

[0059] Optionally, the strength of the connection structure of the magnetic curtain is greater than or equal to a predetermined strength. Among them, the connection structure of the magnetic curtain may include a fixing structure between the magnetic structure and the curtain body, a connection structure between the magnetic curtain and the vehicle, etc. In implementation, the connection structure of the magnetic curtain may adopt stitches, rivets, buckles, etc. with a strength greater than or equal to the predetermined strength. This connection structure meets the requirements of fatigue testing and strength testing. Thus, during use, the risk of damage to the magnetic curtain caused by acting forces such as pulling force and vibration force can be effectively reduced. Furthermore, the magnetic curtain can operate stably and reliably within a predetermined service life, without the need for frequent replacement and repair, greatly reducing the use cost of the magnetic curtain and improving the user experience.

[0060] Optionally, the curtain body includes a first composite layer, a second composite layer, and a third composite layer that are sequentially stacked. Among them, the first composite layer is provided with a waterproof coating, and this waterproof coating has a nano-scale pore structure, so as to be able to effectively prevent the penetration of liquid water and allow the smooth passage of water vapor molecules. Furthermore, it can effectively ensure the humidity balance inside and outside the curtain body and prevent water vapor from condensing on the inner side of the curtain. The second composite layer uses a rubber waterproof diaphragm, and the density of this rubber waterproof diaphragm is greater than a predetermined density. Thus, the curtain body has an extremely low water permeability, and even under the action of long-term water pressure, it can effectively block the penetration of water, providing a reliable waterproof barrier for the curtain body. The third composite layer uses waterproof non-woven fabric. Among them, the magnetic structure can be arranged on the third composite layer. Thus, it can ensure that the magnetic structure is not eroded by water, guarantee the magnetic performance of the magnetic structure, and at the same time, further enhance the overall waterproofness of the curtain body.

[0061] Optionally, a thermoplastic rubber sealing strip is provided at the edge of the curtain body. Among them, this thermoplastic rubber sealing strip can be seamlessly bonded through a high-temperature and high-pressure process, so as to be able to form a continuous and tight sealing ring. When the curtain body is adsorbed on the car door frame, this thermoplastic rubber sealing strip can be in close extrusion contact with the car door frame, effectively filling any tiny gaps. Furthermore, it can effectively prevent rainwater from seeping in from the edge, further improving the waterproofness of the curtain body. At the same time, the fatigue life of this thermoplastic rubber sealing strip is greater than or equal to the target life length, making this thermoplastic rubber sealing strip have good elastic recovery ability. During the use of the magnetic curtain, the risk of the thermoplastic rubber sealing strip losing its waterproof function due to deformation can be effectively reduced, so that this thermoplastic rubber sealing strip can always maintain good sealing performance within the service life.

[0062] Optionally, the magnetic curtain further includes a first wrapping structure for wrapping the connection structure between the magnetic curtain and the vehicle. The first wrapping structure is a waterproof and sealed structure. For example, it can be a waterproof and sealed rubber sleeve. The connection structure between the magnetic curtain and the vehicle is completely wrapped by the first wrapping structure, so that the connection structure is completely isolated from the outside. Thus, during the use of the magnetic curtain, it can effectively prevent the connection structure from being corroded by pollutants such as rainwater, and further improve the stability of the magnetic curtain during use.

[0063] Optionally, the magnetic curtain further includes a second wrapping structure for wrapping the target structure in the folding mechanism of the magnetic curtain. The target structure is such as a driving motor, an electric reel, etc. The second wrapping structure is a waterproof and sealed structure. For example, it can be a waterproof and sealed housing. The protection level of the second wrapping structure can be higher than or equal to the target protection level to ensure that the target component will not be damaged due to water ingress in harsh environments such as when the vehicle wades through water or encounters heavy rain, and thus can ensure the effective operation of the magnetic curtain.

[0064] Optionally, the curtain body is made of a breathable fabric, and the pore size of the breathable fabric is smaller than a predetermined size. For example, the breathable fabric can be made of a blend of polyester fiber and natural cotton fiber, so that it can effectively prevent the entry of small insects such as mosquitoes, and can ensure the breathability of the curtain body, so that good ventilation can be maintained inside the vehicle.

[0065] Optionally, the curtain body is coated with an anti-mosquito agent layer, and the anti-mosquito agent layer can be an environment-friendly anti-mosquito agent layer, using plant extracts as the main active ingredients, such as lemon eucalyptus oil, citronella oil, etc., which have a strong repellent effect on mosquitoes, are harmless to the human body, and have no pungent smell, so as to further improve the user experience. Among them, the anti-mosquito agent layer is wrapped by nano-microcapsule technology, so that it can slowly and continuously release the mosquito-repellent component, so as to effectively protect the interior of the vehicle from mosquito infestation and further improve the user experience.

[0066] As Figure 1 shown, the control method of the magnetic curtain in this embodiment includes:

[0067] S101. When receiving an opening signal of a target vehicle door, identify the current state of the curtain body.

[0068] Specifically, the target door can be the door provided with a magnetic curtain. The opening signal of the target door can be sent by the door controller to the curtain controller. For example, when the door controller determines that the target door meets the door opening condition, it can send the opening signal of the target door to the curtain controller. At the same time, the door controller can also control the opening of the target door. Among them, when the door controller receives the door opening instruction corresponding to the target door and the target door has no fault, it is determined that the target door meets the door opening condition. In implementation, the door controller can communicate with the curtain controller through the CAN bus or dedicated communication line inside the vehicle to achieve the linkage control of the door and the magnetic curtain.

[0069] When the curtain controller receives the opening signal of the target door, it can identify the current state of the curtain body. The current state of the curtain body can be the unfolded state (i.e., the magnetic curtain is fully unfolded), the folded state (i.e., the magnetic curtain is fully folded), the dynamic unfolding state (i.e., the magnetic curtain is unfolding), or the dynamic folding state (i.e., the magnetic curtain is folding).

[0070] S102. If the current state of the curtain body is the unfolded state, wait for a predetermined time length and then control the magnetic force of the magnetic structure to decrease. When the magnetic force of the magnetic structure reaches the first target magnetic force, control the folding mechanism to fold the curtain body; where the predetermined time length is greater than 0 and less than the predetermined opening time length of the target door.

[0071] Specifically, if the current state of the curtain body is the unfolded state, it can wait for a predetermined time length and then control the curtain body to be desorbed and folded. The predetermined time length is greater than 0 and less than the predetermined opening time length of the target door. The predetermined opening time length of the target door can be the time required for the target door to be fully opened from the closed state in the normal state (for example, the target door has no fault and there are no obstacles or other factors affecting the opening of the target door). For example, the predetermined time length can be 0.5 s to 1 s. That is, after the target door is opened to a certain extent, the curtain body can be controlled to be desorbed and folded, so as to effectively reduce the risk of damage to the curtain body caused by the curtain body being involved in the mechanical structure of the target door during the opening process of the door.

[0072] Among them, when the duration of receiving the opening signal of the target door reaches the predetermined time length, first control the magnetic force of the magnetic structure on the curtain body to decrease. For example, the current applied to the magnetic structure can be reduced to reduce the magnetic force of the magnetic structure. When the magnetic force of the magnetic structure decreases to the first target magnetic force, control the folding mechanism to fold the curtain body. For example, the driving motor can be controlled to run in the corresponding direction to drive the electric scroll to fold the curtain body.

[0073] During implementation, the current applied to the magnetic attraction structure can be gradually reduced in a predetermined step size to smoothly reduce the magnetic attraction force of the magnetic attraction structure, so as to effectively ensure the adsorption stability of the magnetic attraction structure while reducing the magnetic attraction force of the magnetic attraction structure, avoiding vibrations and the like of the magnetic attraction structure caused by rapid changes in the magnetic attraction force, and further avoiding damage to the magnetic attraction structure and the curtain body during the vibration process, and at the same time avoiding the noise impact caused by the vibration of the magnetic attraction structure.

[0074] Among them, the first target magnetic attraction force can be greater than 0, so that during the process of folding the curtain body, the curtain body is adsorbed on the car door frame with a smaller adsorption force, ensuring the flatness of the curtain body during the folding process, thereby effectively avoiding damage to the curtain body due to fluttering or other reasons during the folding process, reducing the power demand for the driving motor during the folding process, and at the same time, the curtain body is adsorbed on the car door frame with a smaller adsorption force, which can avoid damage to the curtain body due to excessive pulling force during the folding process.

[0075] During implementation, during the process of gradually reducing the current applied to the magnetic attraction structure in a predetermined step size, when the target desorption duration is reached, it can be determined that the magnetic attraction force of the magnetic attraction structure reaches the first target magnetic attraction force, and the target desorption duration can be determined according to the size of the predetermined step size. For example, the target desorption duration can be 0.3s - 0.5s.

[0076] It can be understood that the first target magnetic attraction force can also be equal to 0.

[0077] In addition, if the current state of the curtain body is the folded state, it indicates that the magnetic attraction curtain does not affect the opening of the target car door and the entry and exit of personnel. At this time, there is no need to control the magnetic attraction curtain, that is, to maintain the current state of the magnetic attraction curtain.

[0078] If the current state of the curtain body is the dynamic unfolding state, it indicates that the user has input a curtain manual control instruction for controlling the unfolding of the curtain body before inputting the car door opening instruction corresponding to the target car door. At this time, the curtain manual control instruction can be continued to be executed, that is, to control the curtain body to continue to unfold. In addition, the folding mechanism can also be controlled to fold the curtain body, which can be specifically set according to actual needs.

[0079] If the current state of the curtain body is the dynamic folding state, it indicates that the user has input a curtain manual control instruction for controlling the folding of the curtain body before inputting the car door opening instruction corresponding to the target car door. At this time, the folding of the magnetic attraction curtain can be continued until the folding is completed.

[0080] In a feasible implementation manner, the controlling the folding mechanism to fold the curtain body includes:

[0081] Identify the current opening state of the target vehicle door;

[0082] Based on the current opening state of the target vehicle door, determine the current winding speed of the curtain body;

[0083] Based on the current winding speed, control the winding mechanism to wind the curtain body.

[0084] Specifically, the current opening state of the target vehicle door can represent the current opening degree of the target vehicle door. For example, it can be the current opening angle or the current opening percentage of the target vehicle door.

[0085] In implementation, during the process of controlling the winding mechanism to wind the curtain body, the current opening state of the target vehicle door can be obtained in real time, and based on the current opening state of the target vehicle door, the current winding speed of the curtain body can be determined to ensure that the winding speed of the curtain body matches the opening speed of the target vehicle door, so as to further reduce the risk of damage to the curtain body caused by the curtain body being involved in the mechanical structure of the target vehicle door, etc., and it is convenient for people to get on and off the vehicle after the target vehicle door is opened.

[0086] Optionally, based on the current opening state of the target vehicle door and the predetermined correspondence between the opening state of the target vehicle door and the winding height of the curtain body, the target winding height of the curtain body can be determined, and based on the target winding height of the curtain body and the current winding height of the curtain body, the current winding speed of the curtain body can be determined.

[0087] Among them, based on the current winding speed of the curtain body, the winding mechanism can be controlled to wind the curtain body. For example, based on the current winding speed of the curtain body and the predetermined correspondence between the winding speed and the rotation speed of the driving motor, the target rotation speed of the driving motor can be determined, and based on the target rotation speed of the driving motor, the driving motor can be controlled to operate to realize the winding of the curtain body at the current winding speed. And by updating the winding speed of the curtain body in real time, it can effectively ensure that the winding speed of the curtain body matches the opening speed of the target vehicle door, so as to further reduce the risk of damage to the curtain body caused by the curtain body being involved in the mechanical structure of the target vehicle door, etc., and it is convenient for people to get on and off the vehicle after the target vehicle door is opened.

[0088] It can be understood that when the current opening state of the target vehicle door does not change within a specified duration, for example, the target vehicle door fails or there are obstacles at the corresponding position of the target vehicle door, etc., the winding mechanism can be controlled to wind the curtain body based on the target winding speed. The target winding speed can be the latest determined winding speed of the curtain body, or it can also be a default value, which can be specifically set according to actual needs.

[0089] In a feasible implementation manner, it further includes:

[0090] When receiving the closing signal of the target vehicle door, obtain the current state of the curtain body;

[0091] If the current state of the curtain body is in a folded state, control the folding mechanism to release the curtain body.

[0092] Specifically, the closing signal of the target vehicle door can be sent from the vehicle door controller to the curtain controller. In implementation, the vehicle door controller can also, during the closing process of the target vehicle door, obtain the current closing state of the target vehicle door in real time, and when the current closing state of the target vehicle door reaches a predetermined state, send the closing signal of the target vehicle door to the curtain controller. Among them, the current closing state of the target vehicle door can be used to represent the current closing degree of the target vehicle door. For example, it can be the current closing percentage of the target vehicle door. The predetermined state can be a state where the target vehicle door is approaching the completion of closing. For example, when the current closing percentage of the target vehicle door is greater than or equal to the predetermined closing percentage, it is determined that the current closing state of the target vehicle door reaches the predetermined state.

[0093] When the curtain controller receives the closing signal of the target vehicle door, it can identify the current state of the curtain body. The current state can be an unfolded state (i.e., the magnetic attraction curtain is fully unfolded), a folded state (i.e., the magnetic attraction curtain is fully folded), a dynamic unfolding state (i.e., the magnetic attraction curtain is unfolding), or a dynamic folding state (i.e., the magnetic attraction curtain is folding).

[0094] If the current state of the curtain body is in a folded state, the folding mechanism can be controlled to release the curtain body. For example, the driving motor can be controlled to run in a corresponding direction to drive the electric reel to release the curtain body, so as to realize the gradual unfolding of the curtain body. It can be understood that the curtain body can also unfold under the action of its own gravity, so that during the driving of the vehicle, the window can be opened for ventilation, and rain protection, mosquito prevention, etc. can be achieved.

[0095] It can be understood that when receiving the closing signal of the target vehicle door, if the current state of the curtain body is in an unfolded state, it indicates that the user has manually controlled the magnetic attraction curtain to unfold before inputting the vehicle door closing instruction corresponding to the target vehicle door. At this time, the current state of the curtain body can be kept unchanged.

[0096] When receiving the closing signal of the target vehicle door, if the current state of the curtain body is in a dynamic unfolding state or a dynamic folding state, it indicates that the user has input a curtain manual control instruction for controlling the unfolding or folding of the curtain body before inputting the vehicle door closing instruction corresponding to the target vehicle door. At this time, the curtain manual control instruction can be continued to be executed.

[0097] In a feasible implementation manner, it further includes:

[0098] During the process of controlling the folding mechanism to release the curtain body, identify the current position of the curtain body;

[0099] If the current position of the curtain body meets the magnetic attraction condition, control the magnetic attraction force of the magnetic attraction structure to increase to a second target magnetic attraction force, and the second target magnetic attraction force is greater than the first target magnetic attraction force.

[0100] Specifically, during the process of controlling the folding mechanism to release the curtain body, the current position of the curtain body can be obtained in real time. For example, a position detection device can be set on the door frame to detect the position of the curtain body in real time through the position detection device and send it to the curtain controller.

[0101] The curtain controller can determine whether the magnetic attraction condition is met based on the current position of the specified area of the curtain body. The specified area can be an area such as the lower edge of the curtain body. Among them, the curtain controller can determine the distance between the curtain body and the door frame and the alignment state between the curtain body and the door frame according to the current position of the specified area of the curtain body, and determine whether the magnetic attraction condition is met according to the distance and the alignment state. For example, when the distance between the curtain body and the door frame is less than or equal to a predetermined distance and the curtain body is aligned with the door frame, it is determined that the magnetic attraction condition is met; otherwise, it is determined that the magnetic attraction condition is not met.

[0102] When the magnetic attraction condition is not met, it is possible to repeatedly determine whether the current position of the curtain body meets the magnetic attraction condition. When the magnetic attraction condition is met, the magnetic attraction force of the magnetic attraction structure can be controlled to increase to the second target magnetic attraction force. For example, a predetermined current can be applied to the magnetic attraction structure to make the magnetic attraction force of the magnetic attraction structure increase to the second target magnetic attraction force, and the second target magnetic attraction force is greater than the first target magnetic attraction force, so as to firmly adsorb the curtain body on the door frame, thereby effectively ensuring the sealing performance of the magnetic curtain, and further effectively blocking the entry of external dust, noise and heat through the magnetic curtain.

[0103] In a feasible implementation manner, controlling the folding mechanism to fold or release the curtain body includes:

[0104] Identify the obstacle detection result of the target area of the curtain body;

[0105] If the obstacle detection result indicates that there is an obstacle in the target area, control the folding mechanism to stop running, or control the folding mechanism to run in the opposite direction to the current running direction for a target duration.

[0106] Specifically, during the process of controlling the folding mechanism to fold or release the curtain body, the obstacle detection result of the target area of the curtain body can be obtained in real time. The obstacle detection result can be used to characterize whether there are obstacles in the target area, such as fingers, clothes, and other small items. The target area of the curtain body can include the edge of the curtain body and can also include the peripheral area of the curtain body, etc.

[0107] In implementation, obstacle detection devices can be arranged at the edge and bottom of the curtain body to detect in real time whether there are obstacles in the target area of the curtain body through the obstacle detection devices during the process of folding or releasing the curtain body. Among them, if there are no obstacles in the target area, the folding mechanism is controlled to continue running to control the curtain body to fold or release according to the corresponding instructions; if there are obstacles in the target area, the folding mechanism is controlled to stop running. In addition, the folding mechanism can also be controlled to run in the direction opposite to the current running direction for a target duration to release the obstacles. At the same time, when there are obstacles in the target area, an alarm signal can also be generated and sent out to prompt the user to check and clean the obstacles, so as to effectively avoid damage to the curtain body due to improper opening / closing.

[0108] It can be understood that after the obstacle detection device detects that the obstacles in the target area disappear, the folding mechanism can continue to be controlled to fold or release the curtain body.

[0109] In a feasible implementation manner, it further includes:

[0110] When receiving the curtain manual control instruction, identify the current state of the target vehicle door;

[0111] If the magnetic curtain meets the manual control condition in the current state of the target vehicle door, control the magnetic curtain to unfold or fold based on the curtain manual control instruction.

[0112] Specifically, a manual opening and closing control device can also be set, such as a voice receiver, a button, a component on a touch screen, etc., to realize one-key opening / closing of the curtain body. When the user needs to control the magnetic curtain to fold or unfold, the curtain manual control instruction can be sent through the manual opening and closing control device. The curtain manual control instruction can include a folding instruction and an unfolding instruction.

[0113] When the curtain controller receives the curtain manual control instruction, it can obtain the current state of the target vehicle door. For example, it can obtain the current state of the target vehicle door by communicating with the vehicle door controller. The state of the target vehicle door can include a closed state (i.e., the target vehicle door is closed), an open state (i.e., the target vehicle door is opened), a dynamic closing state (i.e., the target vehicle door is closing), and a dynamic opening state (i.e., the target vehicle door is opening).

[0114] During implementation, the door curtain controller can determine whether the magnetic door curtain meets the manual control conditions based on the current state of the target door. For example, when the current state of the target door is a predetermined door state, it can be determined that the magnetic door curtain meets the manual control conditions; otherwise, it can be determined that the magnetic door curtain does not meet the manual control conditions.

[0115] Among them, if the magnetic door curtain meets the manual control condition, the magnetic door curtain is controlled to be unfolded or folded based on the manual control instruction of the door curtain. For example, in the process of controlling the unfolding of the magnetic door curtain based on the manual control instruction of the door curtain, the folding mechanism can be controlled to release the door curtain body according to the predetermined release speed, and in the process of controlling the folding mechanism to release the door curtain body, the current position of the door curtain body is obtained, so that when the current position of the door curtain body meets the magnetic condition, the magnetic attraction force of the magnetic attraction structure is controlled to increase to the second target magnetic attraction force, so that the door curtain body is adsorbed on the door frame. In the process of controlling the folding of the magnetic door curtain based on the manual control instruction of the door curtain, the magnetic attraction force of the magnetic attraction structure can be controlled to decrease, and when the magnetic attraction force of the magnetic attraction structure is reduced to the first target magnetic attraction force, the folding mechanism is controlled to fold the door curtain body according to the predetermined folding speed.

[0116] In addition, if the magnetic door curtain does not meet the manual control conditions, it is determined whether the magnetic door curtain is currently being opened / closed based on the door signal (such as the target door's opening signal or the target door's closing signal). If so, the magnetic door curtain continues to be opened / closed; if not, the current state of the magnetic door curtain is kept unchanged, thereby effectively avoiding the influence of the magnetic door curtain on the normal electric operation function of the target door.

[0117] In a feasible implementation manner, the method for determining whether the magnetic door curtain meets the manual control condition in the current state of the target door includes:

[0118] If the current state of the target door is a dynamic open state or a dynamic closed state, it is determined that the magnetic door curtain does not meet the manual control condition;

[0119] If the current state of the target door is an open state or a closed state, it is determined that the magnetic door curtain meets the manual control condition.

[0120] Specifically, if the current state of the target door is a dynamic opening state or a dynamic closing state, it indicates that the target door is in the process of opening or closing, that is, the target door is in an action state. At this time, it can be determined that the magnetic door curtain does not meet the manual control conditions, thereby effectively avoiding the manual opening and closing control of the magnetic door curtain during the opening or closing process of the door, causing the magnetic door curtain to be rolled into the mechanical structure of the target door, thereby reducing the risk of damage to the door curtain body, and effectively avoiding the influence of the magnetic door curtain on the normal electric operation function of the target door.

[0121] If the current state of the target vehicle door is the open state or the closed state, it indicates that the target vehicle door is in a non-operating state at the current moment. At this time, it can be determined that the magnetic curtain meets the manual control condition, so that the user can control the opening / closing of the magnetic curtain according to actual needs.

[0122] Thus, through the embodiments of the present application, while improving the comfort and protection of the vehicle interior environment, the influence of the magnetic curtain on the normal electric operation function of the target vehicle door can be avoided.

[0123] In a feasible implementation manner, the curtain body includes a first folding layer and a second folding layer. The second folding layer includes a plurality of horizontally arranged blades, and the grid density of the blades is greater than the grid density of the first folding layer;

[0124] The method further includes:

[0125] In response to the blade adjustment instruction, control each of the blades to perform angle adjustment.

[0126] Specifically, the curtain body may include a first folding layer and a second folding layer, that is, the curtain body may adopt a double-layer structure. Among them, the second folding layer may include a plurality of horizontally arranged blades, that is, the direction of the horizontal axis of the blades is perpendicular to the folding direction of the curtain body.

[0127] For any blade in the second folding layer, the grid density of the blade may be greater than the grid density of the first folding layer, that is, the pores in the blade are smaller than the pores in the first folding layer. Thus, the air permeability of the first folding layer is better than that of the second folding layer, but the airtightness of the second folding layer is better than that of the first folding layer, that is, the second folding layer can better prevent mosquitoes, dust, noise, etc.

[0128] Among them, each blade in the second folding layer can rotate around its horizontal axis. For example, it can rotate from 0° to 90°, so as to adjust the air permeability and airtightness of the curtain body by adjusting the angles of the blades. It can be understood that when the angles of all the blades in the second folding layer are 0°, all the blades are parallel to the first folding layer, and the airtightness of the curtain body is the best. When the angles of all the blades in the second folding layer are 90°, all the blades are perpendicular to the first folding layer, and the air permeability of the curtain body is the best.

[0129] During implementation, a manual blade adjustment device can be set up, such as a voice receiver, a button, a component on a touch screen, etc., to control the rotation angle of the blades. The user can send a blade adjustment instruction through the manual blade adjustment device according to the environment where the vehicle is located or personal needs, etc. The curtain controller can control each blade to adjust its angle based on the blade adjustment instruction, so as to meet the different needs of the user for the interior environment of the vehicle, effectively improving the comfort and protection of the interior environment, and further enhancing the user experience.

[0130] Optionally, the curtain controller can also obtain the current driving mode of the vehicle and / or the current state of charge of the battery in real time, and adjust the running speed of the curtain body based on the current driving mode and / or the current state of charge during the operation (such as rolling or releasing) of the curtain body. For example, when the current driving mode is an energy-saving mode and / or the current state of charge of the battery is lower than a predetermined state of charge, the running speed of the curtain body can be reduced by a predetermined percentage compared to the normal situation, so as to reduce the power demand of the magnetic curtain, reduce the instantaneous current peak value, thereby reducing the power consumption of the vehicle battery and effectively extending the cruising range of the vehicle or reducing the additional power generation load of the engine when the battery is low. Among them, the predetermined percentage can be set according to actual needs, as long as it can ensure the normal operation of the curtain body. For example, it can be 30% - 50%.

[0131] Optionally, the curtain controller can automatically enter the standby mode when the magnetic curtain is in an inactive state (such as long-term parking or the magnetic curtain is not operated during vehicle driving), so as to reduce the power consumption of the curtain controller. Among them, in the standby mode, the curtain controller can only maintain the basic communication connection with the vehicle control system and the weak power supply to the key sensors to monitor whether there is a curtain operation instruction or whether there is an external environment change that needs to be responded to. If the duration of the magnetic curtain being in an inactive state reaches a predetermined threshold (such as 10 minutes), the curtain controller can enter the deep sleep mode. At this time, except for the internal clock circuit that operates with extremely low power consumption to record time information, almost all other circuit power supplies are cut off. It can be understood that when a door signal or a curtain manual control instruction is received, the curtain controller can quickly wake up from the sleep mode and resume the normal working state to ensure a significant energy-saving effect without affecting the use convenience.
