Abstract
Description
Technical Field
[0001] The present invention relates to the field of automobiles, and in particular to a vehicle window management method and a vehicle window management system. Background Art
[0002] The window glass is an important part of the vehicle. It is usually set on the door (such as the front door, rear door) or the roof (such as the sunroof) and is equipped with a one-touch lifting function. When the passenger operates the lifting switch, the drive motor is energized to drive the window glass down. At this time, there is a long distance between the top edge of the window glass and the window frame or door frame, and the window is opened to achieve ventilation; or the window glass is driven to rise and fall. At this time, the top edge of the window glass and the window frame or door frame are in contact and the window is closed to prevent ventilation. Since the window glass adopts a one-touch lifting solution, when the passenger operates the lifting switch and allows the drive motor to drive the window glass, the window glass needs to rise to the highest position before it can stop. There are many problems in this process that need to be paid attention to. For example, when a passenger's limbs (especially the fingers or neck of a child) or other objects are located in the space between the edge of the window glass and the edge of the window frame or door frame, if the passenger operates the lifting switch, the passenger's limbs or other objects will be clamped between the edge of the window glass and the edge of the window frame or door frame, and the clamping force generated between the window glass and the window frame or door frame will cause harm to the passenger and damage to other objects or the window glass and the drive motor used to drive the window glass. In addition, when a living person is forgotten inside the vehicle by a passenger (driver), if the vehicle's windows are closed, it will seriously affect the ventilation and heat dissipation inside the vehicle, and in serious cases (such as when the vehicle is exposed to the sun outdoors), it will cause life-threatening danger to the living person. Therefore, how to manage the vehicle windows to avoid the occurrence of the above problems is a technical problem that the inventor is committed to solving. Summary of the invention

The vehicle window management method can determine the presence of an obstacle in the space between the edge of the vehicle window glass and the edge of the vehicle window frame or the vehicle door frame based on the distance between various parts of the object and the in-vehicle microwave sensor.
[0007] One object of the present invention is to provide a vehicle window management method and a vehicle window management system, wherein after the vehicle windows are closed, the vehicle window management method can detect whether there is a living body inside the vehicle, and control the closing or opening of the window according to the detection result, so that when there is a living body inside the vehicle, ventilation and heat dissipation effects can be ensured to avoid life danger to the living body.

[0067] With reference to the accompanying drawings of the present invention Figure 1A vehicle window management method according to a preferred embodiment of the present invention will be disclosed and described in the following description, wherein the attached Figure 5 A specific application example of the vehicle window management method is shown, wherein the vehicle window management method comprises the steps of: S101, when a vehicle window glass 1001 is driven to move relative to a vehicle window frame or a vehicle door frame 1002 to allow a vehicle 1000 to close the window, detecting whether there is at least one obstacle 2000 in the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002; S102, when it is detected that the obstacle 2000 exists in the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002, preventing the vehicle 1000 from closing the window to avoid the vehicle window glass 1001 and the vehicle window frame or the vehicle door frame 1002 from clamping the obstacle 2000.
[0068] Specifically, when the vehicle 1000 closes the window, the window management method detects whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002. If the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, the window management method does not perform the window closing operation to prevent the vehicle 1000 from closing the window, thereby avoiding the window glass 1001 and the window frame or the door frame 1002 from clamping the obstacle 2000. During the process of closing the window of the vehicle 1000, the window management method detects whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002. If the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, the window management method stops executing the window closing operation to prevent the vehicle 1000 from closing the window, thereby avoiding the window glass 1001 and the window frame or the door frame 1002 from clamping the obstacle 2000.
[0069] In other words, when the passenger sends a window closing command to a driving motor 1004 of the vehicle 1000 through a lifting switch to drive the window glass 1001 to rise and allow the vehicle 1000 to close the window, the window management method can detect whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, and control whether the vehicle 1000 closes the window according to the detection result. In the process of the driving motor 1004 driving the window glass 1001 to rise and allow the vehicle 1000 to close the window, the window management method can detect whether the obstacle 2000 suddenly appears in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, and control whether the vehicle 1000 closes the window according to the detection result. During the entire process, the window management method does not require that the obstacle 2000 contacts any one of the edges of the window glass 1001 and the window frame or door frame 1002, nor does it require that the window glass 1001 and the window frame or door frame 1002 have clamped the obstacle 2000. As long as the obstacle 2000 appears in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or door frame 1002, the window management method can detect the obstacle 2000 and prevent the vehicle 1000 from closing the window, which is particularly important for protecting the obstacle 2000, the window glass 1001 and the drive motor 1004.
[0070] In some embodiments, the obstacle 2000 may be a passenger's limbs, such as the fingers or neck of a young child. When and during the process of closing the window of the vehicle 1000, the window management method can prevent the vehicle 1000 from closing the window after detecting that the passenger's limbs are in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or door frame 1002, so as to avoid the window glass 1001 and the window frame or door frame 1002 clamping the passenger's limbs, thereby avoiding damage to the passenger caused by the window closing operation of the vehicle 1000.
[0071] In other embodiments, the obstacle 2000 may be other objects, such as a child's toy. When the vehicle 1000 is closing the window and during the window closing process, the window management method can prevent the vehicle 1000 from closing the window after detecting that the child's toy is in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, so as to prevent the window glass 1001 and the window frame or the door frame 1002 from clamping the child's toy, thereby avoiding damage to the child's toy, the window glass 1001 and the drive motor 1004 caused by the window closing operation of the vehicle 1000.
[0072] Continue to refer to the attached Figure 1 The vehicle window management method further includes the steps of: S103, detecting whether there is a living body inside the vehicle 1000 after the vehicle 1000 closes the window; S104, when a living body is detected inside the vehicle 1000, allowing the vehicle 1000 to open the window to ensure ventilation and heat dissipation effects of the vehicle 1000, thereby avoiding life danger to the living body.
[0073] In other words, after the vehicle 1000 closes its windows, the vehicle management method can detect whether there is a living organism inside the vehicle 1000, and control the vehicle 1000 to close or open its windows based on the detection result. In this way, when there is a living organism inside the vehicle 1000, ventilation and heat dissipation effects can be ensured to avoid causing life danger to the living organism.
[0074] Preferably, when there are living beings inside the vehicle 1000, the window opening amplitude of the vehicle 1000 is controlled within a reasonable range, so that while the ventilation and heat dissipation effects of the vehicle 1000 are ensured, the living beings can be prevented from autonomously or passively coming out of the windows of the vehicle 1000, thereby effectively protecting the living beings.
[0075] Preferably, when there is a living body inside the vehicle 1000, the window management method controls the drive motor 1004 to drive the window glass 1001 to descend and open the window, and the distance between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 is in the range of 5cm-20cm (including 5cm and 20cm), more preferably 5cm-10cm (including 5cm and 20cm). In this way, while ensuring the ventilation and heat dissipation effects of the vehicle 1000, it is possible to prevent the living body from autonomously or passively coming out of the window of the vehicle 1000, so as to effectively protect the living body.
[0076] It is worth mentioning that the vehicle window glass 1001 of the present invention may be a door glass provided on a vehicle door of the vehicle 1000, or may be a skylight glass provided on a roof of the vehicle 1000. When a living body exists inside the vehicle 1000, in order to ensure the safety of the living body and the vehicle 1000 and to remind other people (e.g., people passing by the vehicle 1000) to pay attention to the existence of the living body inside the vehicle 1000, the vehicle window management method controls the vehicle window glass 1001 implemented as a door glass to descend and open the window.
[0077] In other words, the vehicle window management method controls the vehicle window glass 1001 implemented as a door glass to descend. On the one hand, the vehicle window management method can achieve ventilation and heat dissipation effects for the vehicle 1000. On the other hand, the vehicle window management method can remind other people to pay attention to the presence of living beings inside the vehicle 1000 by controlling the vehicle 1000 to open the window, so as to allow other people to provide timely assistance to the living beings when the living beings are in danger. On the other hand, the vehicle window management method can prevent sunlight from directly entering the interior of the vehicle 1000 through the opened sunroof and causing sunburn to the living beings inside the vehicle 1000, and prevent rain from directly falling into the interior of the vehicle 1000 through the opened sunroof and causing damage to objects inside the vehicle 1000 and injury to living beings.
[0078] Attached Figure 2 A specific example of the vehicle window management method is shown, and the vehicle window management method is applied to the vehicle 1000 to manage the lifting state of the vehicle window glass 1001, wherein the vehicle window management method comprises the steps of:
[0079] S201, when the window of the vehicle 1000 is closed, switching an in-vehicle camera 1005 of the vehicle 1000 from a sleep state to a working state to capture an image of the interior of the vehicle 1000.
[0080] It is worth mentioning that the installation position of the in-vehicle camera 1005 is not restricted in the window management method of the present invention. When the window of the vehicle 1000 is opened, as long as the edge of the window glass 1001, the edge of the window frame and the door frame 1002, and the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 appear in the field of view of the in-vehicle camera 1005, it will be sufficient.
[0081] Preferably, the in-vehicle camera 1005 may be a camera of the vehicle 1000 for monitoring whether the driver is driving fatigued, and is installed above the driving position of the vehicle 1000. Figure 5 .
[0082] Preferably, the in-vehicle camera 1005 is a wide-angle camera, which is equipped with a lens with a short focal length and a wide viewing angle, so that the field of view of the in-vehicle camera 1005 can cover all windows of the vehicle 1000.

These lens elements 10050 respectively have a central light-transmitting area 10051 and a peripheral light-shielding area 10052 surrounding the central light-transmitting area 10051. The central light-transmitting area 10051 allows light to pass through and enter the interior of the in-vehicle camera 1005 for subsequent imaging. The peripheral light-shielding area 10052 prevents light from passing through by absorbing light, so as to reduce stray light and improve the imaging quality of the in-vehicle camera 1005. The first lens element 100501 and the fifth lens element 100505 have positive refractive indices, the object side surface of the central light-transmitting area 10051 of the seventh lens element 100507 is a convex surface, and the image side surface of the central light-transmitting area 10051 of the eighth lens element 10058 is a concave surface. The focal length of the first lens element 100501 is f1, the Abbe number of the second lens element 100502 is V2, the thickness of the central light-transmitting area 10051 of the second lens element 100502 is CT2, the thickness of the central light-transmitting area 10051 of the third lens element 100503 is CT3, the focal length of the fifth lens element 100505 is f5, the thickness of the central light-transmitting area 10051 of the fifth lens element 100505 is CT5, and the thickness of the central light-transmitting area 10051 of the seventh lens element 100507 is CT7, wherein the above parameters satisfy the following conditions: 10<V2<50; 0<f5 / f1<2.85; 1<f5 / CT5<25; 0.1<CT3 / CT2<1.5; 0.1<CT7 / CT5<1.25.
[0083] More preferably, the object side surface of the central light-transmitting area 10051 of the first lens element 100501 is a convex surface, and the image side surface is a flat surface; the object side surface of the central light-transmitting area 10051 of the second lens element 100502 is a convex surface, and the image side surface is a concave surface; the object side surface of the central light-transmitting area 10051 of the third lens element 100503 is a convex surface, and the image side surface is a concave surface; the object side surface of the central light-transmitting area 10051 of the fourth lens element 100504 is The object side surface of the central light-transmitting area 10051 of the fifth lens element 100505 is concave, and the image side surface is convex; the object side surface of the central light-transmitting area 10051 of the sixth lens element 100506 is concave, and the image side surface is convex; the image side surface of the central light-transmitting area 10051 of the seventh lens element 100507 is concave; the object side surface of the central light-transmitting area 10051 of the eighth lens element 100508 is convex.
[0084] More preferably, the areas of the central light-transmitting regions 10051 of the lens elements 10050 on the same projection plane increase successively from the first lens element 100501 to the eighth lens element 100508 , so as to improve the imaging quality of the in-vehicle camera 10050 .
[0085] In some embodiments of the vehicle window management method of the present invention, after the vehicle 1000 is powered on, the in-vehicle camera 1005 is powered and can always remain in a working state.
[0086] In other embodiments of the vehicle window management method of the present invention, the state of the in-vehicle camera 1005 is associated with the state of the drive motor 1004. Specifically, when the user operates the drive motor 1004 through the lifting switch to drive the vehicle window glass 1001 to rise and allow the vehicle 1000 to close the window, the in-vehicle camera 1005 switches from the dormant state to the working state to allow the in-vehicle camera 1005 to capture images of the interior of the vehicle 1000.
[0087] S202, segmenting the image according to the position of the object in the image.
[0088] Generally, the vehicle 1000 is provided with four windows. When the windows are closed, the position of the object inside the vehicle 1000 determines which window of the vehicle 1000 the obstacle 2000 may be located in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or door frame 1002. The position of the object inside the vehicle 1000 can be determined by analyzing the position of the object in the image captured by the in-vehicle camera 1005. In the window management method of the present invention, the image is segmented according to the position of the object in the image captured by the in-vehicle camera 1005, and the segmented image is saved and analyzed, wherein the segmented image contains the object. For example, when the object appears in the lower left corner of the image captured by the in-vehicle camera 1005, the image portion in the lower left corner of the image can be segmented out for saving and analysis, and the image portion in the upper left corner, the image portion in the upper right corner and the image portion in the lower right corner of the image can be discarded, which is conducive to reducing the amount of calculation and greatly improving the efficiency and sensitivity of the window management method.
[0089] S203, performing binarization processing on the segmented image.
[0090] It can be understood that although the window glass 1001 of the vehicle 1000 is light-transmitting, the light transmittance of the window glass 1001 is much lower than the light transmittance of the air. Therefore, if an object extends from the interior to the outside of the vehicle 1000 through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, and the window frame or the door frame 1002 and the seats in the vehicle do not block the field of view of the in-vehicle camera 1005, even if the in-vehicle camera 1005 can capture the image of the entire object, the part of the object located outside the vehicle 1000 is captured by the in-vehicle camera 1005 through the window glass 1001, so the clarity of the part of the object located outside the vehicle 1000 is much lower than the clarity of the part of the object located inside the vehicle 1000. In other words, based on the change in clarity of the object in the image of the in-vehicle camera 1005, it can be determined whether the object extends from the inside of the vehicle 1000 to the outside through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or door frame 1002.
[0091] In order to further reduce the amount of calculation and improve the efficiency and sensitivity of the vehicle window management method, the vehicle window management method can perform a binarization process on the segmented image. For example, in a typical example, the step of performing a binarization process on the segmented image by the vehicle window management method specifically includes: first, identifying the object from the segmented image according to the shape of the object and separating it to define it as an object to be processed, and accordingly, other parts in the segmented image (such as the inherent part of the vehicle 1000) are defined as a background object; secondly, performing a binarization process on the object to be processed, at which time the part of the object to be processed located inside the vehicle 1000 will become a white block, and the part of the object to be processed located outside the vehicle 1000 will become a black block.
[0092] S204: judging, based on the binarization result, whether the object extends from the interior to the exterior of the vehicle 1000 through the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002. S205: judging, when the object extends from the interior to the exterior of the vehicle 1000 through the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002, that the obstacle 2000 exists in the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002.
[0093] Specifically, after the segmented image is binarized, if the binarization result is that there is a black block, then in step S204, the vehicle window management method can determine that the object extends from the vehicle 1000 to the outside through the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002, and in step S205, the vehicle window management method can determine that the obstacle 2000 exists in the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002. On the contrary, after the segmented image is binarized, if the binarization result is that there is no black block, then in step S204, the vehicle window management method can determine that the object is located inside the vehicle 1000 as a whole, and in step S205, the vehicle window management method can determine that the obstacle 2000 does not exist in the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002.
[0094] S206, when it is detected that the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, the vehicle 1000 is prevented from closing the window to avoid the obstacle 2000 being clamped by the window glass 1001 and the window frame or the door frame 1002. In this way, when and during the process of closing the window of the vehicle 1000, the window closing operation of the vehicle 1000 can avoid injuries to passengers, and the window closing operation of the vehicle 1000 can avoid damage to children's toys, the window glass 1001 and the drive motor 1004.
[0095] Attached Figure 3 A specific example of the vehicle window management method is shown, and the vehicle window management method is applied to the vehicle 1000 to manage the lifting state of the vehicle window glass 1001, wherein the vehicle window management method comprises the steps of:
[0096] S301, when the window of the vehicle 1000 is closed, a microwave sensor 1006 in the vehicle 1000 is switched from a dormant state to an active state, so as to allow the microwave sensor 1006 to radiate microwaves to the surroundings and receive echoes.
[0097] It is worth mentioning that the installation position of the in-vehicle microwave sensor 1006 is not limited in the vehicle window management method of the present invention, as long as the microwave generated by the in-vehicle microwave sensor 1006 can be radiated to the vehicle window glass 1001 and the vehicle window frame or vehicle door frame 1002 of each vehicle window. For example, in a specific example of the present invention, the number of the in-vehicle microwave sensor 1006 can be one, which is installed at the center of the roof of the vehicle 1000, so as to allow the microwave generated by one in-vehicle microwave sensor 1006 to radiate to the vehicle window glass 1001 and the vehicle window frame or vehicle door frame 1002 of all vehicle windows.
[0098] Preferably, in some embodiments of the vehicle window management method of the present invention, the state of the vehicle window microwave sensor 1006 is associated with the state of the driving motor 1004. Specifically, when the user operates the driving motor 1004 through the lifting switch to drive the vehicle window glass 1001 to rise and allow the vehicle 1000 to close the window, the in-vehicle microwave sensor 1006 switches from the dormant state to the working state, so as to allow the in-vehicle microwave sensor 1006 to radiate microwaves to the surroundings and receive echoes.
[0099] S302 , analyzing the distance between each part of the object and the in-vehicle microwave sensor 1006 , the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006 , and the distance relationship between the edge of the window frame or door frame 1002 and the in-vehicle microwave sensor 1006 .
[0100] It can be understood that, according to the Doppler effect, based on the microwaves radiated by the in-vehicle microwave sensor 1006 to various parts of the object and the echoes received by various parts of the object, the vehicle window management method can determine the distance between various parts of the object and the in-vehicle microwave sensor 1006. If the object is in motion, the vehicle window management method can also determine the movement mode of the object. That is to say, when the in-vehicle microwave sensor 1006 is in working state and radiates microwaves to the surroundings, the window management method can determine the distance between each part of the object and the in-vehicle microwave sensor 1006 according to the echo reflected by each part of the object received by the in-vehicle microwave sensor 1006, the window management method can determine the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006 according to the echo reflected by the edge of the window glass 1001 received by the in-vehicle microwave sensor 1006, and the window management method can determine the distance between the edge of the window frame or door frame 1002 and the in-vehicle microwave sensor 1006 according to the echo emitted by the edge of the window frame or door frame 1002 received by the in-vehicle microwave sensor 1006.
[0101] It can be understood that after respectively determining the distance between each part of the object and the in-vehicle microwave sensor 1006, the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006, and the distance between the edge of the window frame or door frame 1002 and the in-vehicle microwave sensor 1006, the window management method can analyze the distance relationship between each part of the object and the in-vehicle microwave sensor 1006, the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006, and the distance between the edge of the window frame or door frame 1002 and the in-vehicle microwave sensor 1006.
[0102] S303: According to the analysis result, it is determined whether the distance between each part of the object and the in-vehicle microwave sensor 1006 is smaller than the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006 and the distance between the edge of the window frame or door frame 1002 and the in-vehicle microwave sensor 1006. S304: When the distance between at least a part of the object and the in-vehicle microwave sensor 1006 is larger than the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006 and the distance between the window frame or door frame 1002 and the in-vehicle microwave sensor 1006, it is determined that the obstacle 2000 exists in the space between the edge of the window glass 1001 and the edge of the window frame or door frame 1002. S305, when it is detected that the obstacle 2000 exists between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, the vehicle 1000 is prevented from closing the window to avoid the window glass 1001 and the window frame or the door frame 1002 from clamping the obstacle 2000, so that when and during the process of closing the window of the vehicle 1000, the window closing operation of the vehicle 1000 can avoid harm to passengers, and the window closing operation of the vehicle 1000 can avoid damage to children's toys, the window glass 1001 and the drive motor 1004.
[0103] Reference Figure 4 According to another aspect of the present invention, the present invention further provides a vehicle window management system, which may be a system or program running on a driving computer of the vehicle 1000, and includes a processor 401, a memory 402, a power supply component 403, a communication component 404, and an input / output interface 405. The processor 401 is coupled to the memory 402, the power supply component 403, the communication component 404, and the input / output interface 405. The processor 401 is used to read and execute instructions stored in the memory 402, and the instructions may be codes or scripts. The power supply component 403 is used to provide the processor 401, the memory 402, and the communication component 404 with the input / output interface 405. 02 and the communication component 404 provide power, the communication component 404 is used to realize the communication between the window management system and the external environment, for example, the communication component 404 can be used to realize the communication between the window management system and the driving motor 1004 of the vehicle 1000, the in-vehicle camera 1005 and / or the in-vehicle microwave sensor 1006, the input / output interface 405 is used to realize the connection between the window management system and the external environment, for example, the input / output interface 405 can be used to realize the connection between the window management system and the driving motor 1004 of the vehicle 1000, the in-vehicle camera 1005 and / or the in-vehicle microwave sensor 1006.
[0104] The processor 401 of the window management system may be permanently or temporarily configured with a plurality of units, which may include a detection unit 10 and a control unit 20, that is, the window management system includes the detection unit 10 and the control unit 20 communicatively connected to the detection unit 10, wherein the detection unit 10 is used to detect whether the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 is closed when the window glass 1001 is driven to move relative to the window frame or the door frame 1002 to allow the vehicle 1000 to close the window. The obstacle 2000 exists, wherein the control unit 20 is used to prevent the vehicle 1000 from closing the window when it is detected that the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, so as to avoid the obstacle 2000 being clamped by the window glass 1001 and the window frame or the door frame 1002, thereby avoiding damage to passengers caused by the window closing operation of the vehicle 1000, and avoiding damage to children's toys, the window glass 1001 and the drive motor 1004 caused by the window closing operation of the vehicle 1000.
[0105] In some embodiments of the present invention, the input / output interface 405 of the window management system can be connected to the in-vehicle camera 1005 of the vehicle 1000, and the communication component 404 can realize communication between the window management system and the in-vehicle camera 1005, so that when the processor 401 of the window management system executes the instructions stored in the memory 402, it allows the detection unit 10 to detect whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or door frame 1002 based on the image of the interior of the vehicle 1000 taken by the in-vehicle camera 1005.
[0106] Specifically, the detection unit 10 further includes a state switching module 11 and a judgment module 12, wherein the state switching module 11 is used to switch the in-vehicle camera 1005 of the vehicle 1000 from a sleep state to a working state to capture an image of the interior of the vehicle 1000 when the window of the vehicle 1000 is closed, and the judgment module 12 is used to judge whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 based on the image captured by the in-vehicle camera 1005.
[0107] Preferably, the state switching module 11 is used to switch the in-vehicle camera 1005 from a dormant state to a working state when the window of the vehicle 1000 is closed by associating the state of the in-vehicle camera 1005 with the state of the driving motor 1004. Specifically, when the passenger sends a window closing instruction to the driving motor 1004 of the vehicle 1000 through a lifting switch to drive the window glass 1001 to rise and allow the window of the vehicle 1000 to be closed, the state switching module 11 switches the in-vehicle camera 1005 from a dormant state to a working state, and the in-vehicle camera 1005 can capture images of the interior of the vehicle 1000. Preferably, in the process of the driving motor 1004 driving the window glass 1001 to rise, the state switching module 11 can control the in-vehicle camera 1005 to remain in a working state and continuously capture images of the interior of the vehicle 1000.
[0108] The judgment module 12 further includes a segmentation submodule 121, a processing submodule 122, an analysis submodule 123 and a judgment submodule 124, wherein the segmentation submodule 121 is used to segment the image captured by the in-vehicle camera 1005, wherein the processing submodule 122 is used to perform binarization processing on the image segmented by the segmentation submodule 121, wherein the analysis submodule 123 is used to analyze the color change of the object contained in the image captured by the in-vehicle camera 1005, wherein the judgment submodule 124 is used to judge whether the object contained in the image captured by the in-vehicle camera 1005 extends from the inside of the vehicle 1000 to the outside through the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002 according to the analysis result of the analysis submodule 123, and if the object contained in the image captured by the in-vehicle camera 1005 extends from the inside of the vehicle 1000 to the outside through the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002, 1000 extends from the inside to the outside, the judging submodule 124 judges that the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, and at this time, the control unit 20 prevents the vehicle 1000 from closing the window to avoid the injury to the passengers caused by the window closing operation of the vehicle 1000, and to avoid the damage to the toys of the children, the window glass 1001 and the driving motor 1004 caused by the window closing operation of the vehicle 1000. Correspondingly, if the object contained in the image captured by the in-vehicle camera 1005 extends from the interior to the exterior of the vehicle 1000 without passing through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, the judgment submodule 124 judges that the obstacle 2000 does not exist in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, and at this time the control unit 20 allows the vehicle 1000 to close the window.
[0109] Specifically, after the state switching module 11 switches the state of the in-vehicle camera 1005 from the dormant state to the working state to allow the in-vehicle camera 1005 to capture the image of the interior of the vehicle 1000, the segmentation submodule 121 segments the image captured by the in-vehicle camera 1005, and saves and analyzes the segmented image, wherein the segmented image contains an object. For example, when an object appears in the lower left corner of the image captured by the in-vehicle camera 1005, the segmentation submodule 121 can segment the image portion in the lower left corner of the image for saving and analysis, and the image portion in the upper left corner, the image portion in the upper right corner, and the image portion in the lower right corner of the image can be discarded, which is conducive to reducing the amount of calculation and greatly improving the efficiency and sensitivity of the window management system.
[0110] The processing submodule 122 can perform binarization processing on the image segmented by the segmentation submodule 121. It can be understood that, although the window glass 1001 of the vehicle 1000 is light-transmitting, the light transmittance of the window glass 1001 is much lower than the light transmittance of air. Therefore, if an object extends from the inside of the vehicle 1000 to the outside through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or door frame 1002, and the window frame or door frame 1002 and the seat in the vehicle do not block the field of view of the in-vehicle camera 1005, even if the in-vehicle camera 1005 can capture the image of the entire object, the part of the object located outside the vehicle 1000 is captured by the in-vehicle camera 1005 through the window glass 1001, so the clarity of the part of the object located outside the vehicle 1000 is much lower than the clarity of the part of the object located inside the vehicle 1000. In other words, it can be determined whether the object extends from the inside of the vehicle 1000 to the outside through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or door frame 1002 according to the change in clarity of the object in the image of the in-vehicle camera 1005. In order to further reduce the amount of calculation and improve the efficiency and sensitivity of the window management system, the processing submodule 122 of the judgment module 12 of the detection unit 10 of the window management system can perform binarization processing on the image segmented by the segmentation submodule 121.
[0111] For example, in a typical example, the processing submodule 122 further includes an identification part and a binarization part, wherein the identification part is used to identify the object according to the shape of the object from the image segmented by the segmentation submodule 121 and separate it, and then define it as the object to be processed and define the other part as the background object, wherein the binarization part is used to binarize the object to be processed so that the part of the object to be processed located inside the vehicle 1000 will become a white block, and the part of the object to be processed located outside the vehicle 1000 will become a black block.
[0112] The analysis submodule 123 analyzes whether the object extends from the interior to the exterior of the vehicle 1000 through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 based on the binarization result of the processing submodule 122. If the object extends from the interior to the exterior of the vehicle 1000 through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, the judgment submodule 124 judges whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002. Correspondingly, if the object extends from the interior to the outside of the vehicle 1000 without passing through the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002, the judgment submodule 124 determines that the obstacle 2000 does not exist in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002.
[0113] In addition, after the window of the vehicle 1000 is closed, the state switching module 11 can switch the in-vehicle camera 100 of the vehicle 1000 from the sleep state to the working state to capture the image of the interior of the vehicle 1000. The judgment module 12 judges whether there is a living body inside the vehicle 1000 according to the image captured by the in-vehicle camera 1005. If the judgment module 12 judges that there is a living body inside the vehicle 1000 according to the image captured by the in-vehicle camera 1005, the control unit 20 controls the driving motor 1004 to drive the window glass 1001 to descend and open the window, and the distance between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 ranges from 5 cm to 20 cm (including 5 cm and 20 cm), and more preferably ranges from 5 cm to 10 cm (including 5 cm and 20 cm). In this way, while ensuring the ventilation and heat dissipation effects of the vehicle 1000, it is possible to prevent the living body from autonomously or passively coming out of the window of the vehicle 1000, so as to effectively protect the living body.
[0114] In other embodiments of the present invention, the input / output interface 405 of the window management system can be connected to the in-vehicle microwave sensor 1006 of the vehicle 1000, and the communication component 404 can realize communication between the window management system and the in-vehicle microwave sensor 1006, so that when the processor 401 of the window management system executes the instructions stored in the memory 402, it allows the detection unit 10 to detect whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 based on the microwaves radiated to the surroundings and the received echoes by the in-vehicle microwave sensor 1006.
[0115] In this embodiment, the state switching module 11 of the detection unit 10 is used to switch the in-vehicle microwave sensor 1006 of the vehicle 1000 from a sleep state to a working state when the window of the vehicle 1000 is closed, allowing the in-vehicle microwave sensor 1006 to radiate microwaves and receive echoes in all directions, and the judgment module 12 is used to judge whether the obstacle 2000 exists in the space 1003 between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 based on the microwaves radiated and the echoes received by the in-vehicle microwave sensor 1006.
[0116] Preferably, the state switching module 11 is used to switch the in-vehicle microwave sensor 1006 from a dormant state to a working state when the window of the vehicle 1000 is closed by associating the state of the in-vehicle microwave sensor 1006 with the state of the drive motor 1004. Specifically, when the passenger sends a window closing instruction to the drive motor 1004 of the vehicle 1000 through a lifting switch to drive the window glass 1001 to rise and allow the vehicle 1000 to close the window, the state switching module 11 switches the in-vehicle microwave sensor 1006 from a dormant state to a working state, and at this time, the in-vehicle microwave sensor 1006 can radiate microwaves and receive echoes to the surroundings. Preferably, in the process of the drive motor 1004 driving the window glass 1001 to rise, the state switching module 11 can control the in-vehicle microwave sensor 1006 to remain in a working state and continuously radiate microwaves and receive echoes to the surroundings.
[0117] Further, the analyzing submodule 123 of the judging module 12 is used to analyze the distance between each part of the object and the in-vehicle microwave sensor 1006, the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006, and the distance between the edge of the window frame or the door frame 1002 and the in-vehicle microwave sensor 1006 according to the microwaves radiated to the surroundings by the in-vehicle microwave sensor 1006 and the received echoes, wherein the judging submodule 124 is used to judge whether the distance between each part of the object and the in-vehicle microwave sensor 1006 is less than the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006 and the distance between the edge of the window frame or the door frame 1002 and the in-vehicle microwave sensor 1006 according to the analysis result of the analyzing submodule 123, if at least one part of the object is less than the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006, the in-vehicle microwave sensor 1006 is less than the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006, and if at least one part of the object is less than the distance between the edge of the window glass 1001 and the in-vehicle microwave sensor 1006, the in-vehicle microwave sensor 1006 is less than the distance between the edge of the window frame or the door frame 1002 and the in-vehicle microwave sensor 1006. 1006 is greater than or equal to the distance between the edge of the vehicle window glass 1001 and the in-vehicle microwave sensor 1006 and the distance between the edge of the vehicle window frame or the vehicle door frame 1002 and the in-vehicle microwave sensor 1006, the judging submodule 124 judges that the obstacle 2000 exists in the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002; if the distance between each part of the object and the in-vehicle microwave sensor 1006 is less than the distance between the edge of the vehicle window glass 1001 and the in-vehicle microwave sensor 1006 and the distance between the edge of the vehicle window frame or the vehicle door frame 1002 and the in-vehicle microwave sensor 1006, then it is judged that the obstacle 2000 does not exist in the space 1003 between the edge of the vehicle window glass 1001 and the edge of the vehicle window frame or the vehicle door frame 1002.
[0118] In addition, after the window of the vehicle 1000 is closed, the state switching module 11 can switch the in-vehicle microwave sensor 1006 of the vehicle 1000 from the sleep state to the working state, so as to allow the in-vehicle microwave sensor 1006 to radiate microwaves to the surroundings and receive echoes. The judgment module 12 can judge whether there is a living body inside the vehicle 1000 according to the microwaves radiated to the surroundings and the echoes received by the in-vehicle microwave sensor 1006. If the judgment module 12 judges that there is a living body inside the vehicle 1000 according to the microwaves radiated to the surroundings and the echoes received by the in-vehicle microwave sensor 1006, If there is a living body inside the vehicle 1000, the control unit 20 controls the driving motor 1004 to drive the window glass 1001 to descend and open the window, and the distance between the edge of the window glass 1001 and the edge of the window frame or the door frame 1002 is in the range of 5cm-20cm (including 5cm and 20cm), and more preferably 5cm-10cm (including 5cm and 20cm). In this way, while ensuring the ventilation and heat dissipation effects of the vehicle 1000, it is possible to prevent the living body from autonomously or passively coming out of the window of the vehicle 1000, so as to effectively protect the living body.
