[0002] The existing vehicle window anti-pinch function only focuses on preventing foreign objects from being pinched during the lifting of the vehicle window glass.

[0054] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0055] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0056] Current anti-pinch window functions primarily aim to prevent objects from being caught when the window is raised. If the window encounters resistance while rising, such as when it comes into contact with a foreign object, it will stop due to the resistance to prevent injury. This protection mode is passive, meaning the glass comes into contact with the foreign object first; although the object is protected, it may still suffer minor crush damage.

[0057] Therefore, in order to overcome the above-mentioned defects, this application provides a solution that responds to the window glass control command with the initial lifting speed. When a foreign object is detected within the window area, the window glass is controlled by combining the position of the upper edge of the window glass, the position of the foreign object in the space, and the lateral pressure value of the window glass, thereby ensuring that the occurrence of injury is actively prevented to the greatest extent possible during the control of the window glass.

[0058] It should be noted that the executing entity of each embodiment of this application can be a computing service system with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic system or vehicle window control system capable of realizing the above functions. The following description uses a vehicle window control system as an example to illustrate the various embodiments.

[0059] Based on this, this application provides a method for controlling vehicle window glass, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the vehicle window glass control method of this application.

[0060] In this embodiment, the vehicle window glass control method comprises steps S10-S40:

[0061] Step S10, after responding to the vehicle window glass control instruction at different lifting speeds, detecting whether there is foreign matter in the vehicle window range.

[0062] It should be noted that the structure of the vehicle window mainly includes the glass body, the window frame, the guide rail sealing strip and other core components. The vehicle window can generally include front and rear windows, side windows, sunroof windows, etc. The vehicle window glass control system of the present application is mainly for the side window which needs to be frequently lifted and lowered in daily life. As shown in the Figure 2 vehicle window cross-section view, the vehicle window cross-section view shows the upper edge of the vehicle window, the lower edge of the vehicle window and the vehicle window glass.

[0063] It should be understood that during the lifting of the vehicle window glass, if the foreign matter such as fingers, arms or other objects in the vehicle window range cannot be effectively identified and handled, it may cause serious consequences. Therefore, when the vehicle window glass control instruction is received, the present application first responds to the vehicle window glass control instruction at a relatively slow initial lifting speed, and detects whether there is foreign matter in the vehicle window range.

[0064] It can be understood that the initial lifting speed refers to the initial speed when the vehicle window glass starts to act after receiving the control instruction. In order to avoid that the too fast speed may cause a large impact force when the vehicle window glass collides with the foreign matter, thereby increasing the risk of damaging the vehicle window or pinching the passenger, the initial lifting speed is set to a relatively slow speed.

[0065] In addition, it should be noted that the method of detecting whether there is foreign matter in the vehicle window range can be to install distance sensors on the upper edge and the lower edge of the vehicle window, and to judge whether there is foreign matter by measuring the distance from the potential obstacle. In addition, suitable methods or a combination of multiple methods can be selected according to actual needs for comprehensive detection, so as to improve the accuracy and reliability of detection.

[0066] For the convenience of understanding, reference Figure 3 is made to the description, but the present application is not limited thereto. Figure 3 The arrangement diagram of the vehicle window distance sensor is shown in the figure, and the distance sensor is installed on the upper edge and the lower edge of the vehicle window: the distance sensor on the upper edge of the vehicle window is specifically arranged between the vehicle window glass and the inner side of the upper edge guide rail, and its detection direction is along the glass towards the lower edge of the vehicle window. The distance sensor on the lower edge of the vehicle window is specifically arranged between the vehicle window glass and the inner side of the lower edge guide rail or the door guard, and its detection direction is along the glass towards the upper edge of the vehicle window.

[0067] It should be understood that the vehicle window control system always has the ability to monitor foreign matter in the vehicle window range regardless of whether the vehicle window control instruction is received, but such continuous monitoring consumes high energy. In contrast, the method proposed in the present application starts the foreign matter detection mechanism only after receiving the vehicle window control instruction, which is logically more concise and only performs necessary detection before the vehicle window actually moves, thereby significantly reducing the overall power consumption of the system.

[0068] Step S20, when the foreign matter exists in the vehicle window range, acquiring the spatial position of the foreign matter.

[0069] It can be understood that when the foreign matter exists in the vehicle window range, the system will immediately start the corresponding detection mechanism to accurately acquire the spatial position information of the foreign matter.

[0070] It should be noted that the process of detecting and acquiring the spatial position of the foreign matter usually relies on advanced sensor technology, which can monitor the vehicle window area in real time and capture the presence of any abnormal object. At the moment when the foreign matter is detected, the system quickly analyzes and calculates the specific position of the foreign matter, which includes the precise coordinates of the foreign matter in each direction relative to the vehicle window glass, such as front and back, left and right, and up and down.

[0071] Step S30, obtaining the lateral pressure value of the vehicle window glass by detecting the degree of compression of the vehicle window.

[0072] It should be noted that the degree of compression of the vehicle window refers to the slight positional shift of the vehicle window glass when subjected to external force, thereby causing compression of the pressure sensor. Different pressure values correspond to different degrees of compression.

[0073] It can be understood that when the vehicle window glass contacts and is compressed by the foreign matter, a certain lateral pressure will be generated. When the sensor detects abnormal lateral pressure, the control logic can be started to provide safety protection by stopping or changing the lifting speed.

[0074] Step S40, controlling the vehicle window glass according to the upper edge position of the vehicle window glass, the spatial position of the foreign matter, and the lateral pressure value of the vehicle window glass.

[0075] It can be understood that the upper edge position of the glass marks the initial position of the vehicle window glass lifting, i.e., the current position of the vehicle window glass in the vehicle window range. During the lifting of the vehicle window, the system will monitor the relationship between the upper edge position of the glass and the spatial position of the foreign matter in real time and perform corresponding operations.

[0076] It should be understood that whether a foreign matter exists in the vehicle window range and the degree of compression of the vehicle window glass by the foreign matter can be sensed by a sensor, and the lateral pressure value of the vehicle window glass is acquired. In the process of lifting the vehicle window glass, the spatial position of the foreign matter, the upper edge position of the glass, and the lateral pressure value of the vehicle window glass are comprehensively considered to control the vehicle window glass.

[0077] For the convenience of understanding, the description will be made with reference to the accompanying drawings, but the description is not intended to limit the present application. Figure 4 Figure 4 The schematic diagram of the installation position of the window sensor is shown, and the overall arrangement direction is the front-rear direction of the vehicle. The smaller the interval of the sensor arrangement, the higher the accuracy of sensing the spatial position of the foreign object. The initial detection distance of each sensor can be obtained through calibration. When there is a foreign object blocking in the range of the window glass, the distance sensed by the sensor will change obviously, specifically, the distance becomes smaller. By comparing the height of each sensor along the up-down direction of the window, the height position and size of the foreign object on the position of the corresponding sensor can be obtained, that is, the highest position and the lowest position of the foreign object in the range of the window.

[0078] Among them, the strip-shaped pressure sensor is arranged on both sides of the side guide rail of the window, and the overall direction is the up-down direction of the window. When the window glass is pressed by a foreign object, the strip-shaped pressure sensors on both sides of the guide rail will sense the change of the pressure. The greater the pressure value, the greater the degree of pressing of the glass. When the degree of pressing is large, forcibly lifting the window glass will cause potential harm to the foreign object.

[0079] It should be noted that the control of the window glass based on the up position of the window glass, the spatial position of the foreign object and the lateral pressure value of the window glass belongs to a kind of active harm prevention method of the window, and when the above-mentioned active harm prevention action is executed under the condition, the passive window anti-pinch function possessed by the vehicle itself is also integrated, that is, when the window glass is blocked by a foreign object, resistance is generated, and the change of current or motor speed can be sensed by a traditional current sensor or Hall sensor, so that the existence of the foreign object is passively sensed, and the lifting action of the window glass is stopped. In any case, when the passive window anti-pinch function is triggered, the window glass immediately stops lifting.

[0080] In addition, it should be noted that if the window glass lifting instruction of the physical button is received for more than a predetermined period of time, the manual dominant mode is entered, and the system unconditionally executes the operation instruction of the window glass lifting input by the vehicle.

[0081] The embodiment provides a window glass control method, which responds to a window glass control instruction at an initial lifting speed. When it is detected that there is a foreign object in the range of the window, the window glass is controlled based on the up position of the window glass, the spatial position of the foreign object and the lateral pressure value of the window glass, so that the generation of harm is actively prevented to the greatest extent in the process of controlling the window glass.

[0082] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as the above-mentioned embodiment one can be referred to the above description, and will not be described in detail. On this basis, please refer to Figure 5 ​The step S40 can include steps S401-S404.

[0083] Step S401, detecting the positional relationship between the foreign object spatial position and the upper edge position of the vehicle window glass.

[0084] It can be understood that when detecting the positional relationship between the foreign object spatial position and the upper edge of the vehicle window glass, sensor technology can be used to accurately capture the foreign object spatial position information. These information describes the shape, size and exact position of the foreign object in three-dimensional space in detail, and high-level algorithms of image processing and geometric analysis are used to carefully process the captured data to accurately identify and extract the key position points of the lower edge and the upper edge of the foreign object. These position points accurately define the boundaries of the foreign object in the vertical direction.

[0085] Further, by comparing the key position points of the lower edge and the upper edge of the foreign object with the position information of the upper edge of the vehicle window glass, multiple position information can be converted into the same coordinate system to ensure the accuracy and consistency of the comparison. In the comparison process, the vertical and horizontal distances or other between the position points of the lower edge and the upper edge of the foreign object and the upper edge of the vehicle window glass are calculated. Based on the calculation results of these distance values, the detection result of the positional relationship is obtained. Therefore, the step S401 can include: obtaining the position points of the lower edge and the upper edge of the foreign object according to the foreign object spatial position; comparing the position points of the lower edge and the upper edge of the foreign object with the position of the upper edge of the vehicle window glass, respectively, to obtain the positional relationship detection result.

[0086] Step S402, when the positional relationship is that the position points of the upper edge of the foreign object are below the upper edge of the vehicle window glass, and the vehicle window glass control instruction is a vehicle window glass lifting instruction, if the lateral pressure value of the vehicle window glass is less than a first preset pressure threshold, the vehicle window glass lifting instruction is responded at a normal lifting speed.

[0087] It should be noted that in order to improve the control efficiency of the vehicle window glass and improve the user experience, a normal lifting speed is set, and the normal lifting speed is greater than the initial lifting speed.

[0088] It should be understood that the first preset pressure threshold refers to a pressure value limit preset by the system to judge whether the vehicle window is subjected to abnormal lateral resistance during the lifting of the vehicle window glass. This value is usually determined comprehensively according to multiple factors such as the design of the vehicle window system, the bearing capacity of the material, and the safety performance requirements.

[0089] It can be understood that, in a normal lifting process, the lateral pressure on the vehicle window glass should be kept within a reasonable range. If the lateral pressure on the vehicle window glass exceeds the first preset pressure threshold, the system may consider that the vehicle window encounters an obstacle or other abnormal conditions, and thus take appropriate protective measures to avoid injury to the vehicle window system, foreign matter or passengers.

[0090] It can be understood that, after the system determines the positional relationship between the foreign matter and the upper edge of the vehicle window glass through sensors and algorithms, if the detection result shows that all position points of the upper edge of the foreign matter are below the upper edge of the vehicle window glass, i.e., the foreign matter does not block the lifting path of the vehicle window glass, and at this time the received vehicle window glass control instruction is a lifting instruction, and the measured lateral pressure value of the vehicle window glass is less than the first preset pressure threshold of the system, which means that the vehicle window glass will not encounter abnormal resistance in the lifting process, and thus the system can respond to the lifting instruction at a conventional lifting speed, i.e., normally lifting the vehicle window glass.

[0091] Exemplarily, it is assumed that a child A plays with his mouth below the upper edge of the vehicle window glass. At this time, if the system receives a vehicle window glass lifting instruction, it will first detect the positional relationship between the child's mouth (as a foreign matter) and the upper edge of the vehicle window glass. Since the child's mouth is below the upper edge of the vehicle window glass, the system will not immediately stop the lifting of the vehicle window. Next, the system will check the lateral pressure value of the vehicle window glass. If the child does not press against the vehicle window or the sealing of the vehicle window is good, and no abnormal lateral pressure is generated due to the presence of the child (i.e., the lateral pressure value of the vehicle window glass is less than the first preset pressure threshold), then the system will lift the vehicle window glass at a conventional lifting speed.

[0092] It should be noted that, if the control instruction received by the vehicle for lifting the glass is one-key lifting, the instruction is only executed for a preset period of time, and after the preset period of time, the system returns to detecting the vehicle control instruction. Further, if the lateral pressure value of the vehicle window glass changes to exceed the above-mentioned preset threshold range within the preset period of time, the system immediately starts to re-execute the vehicle window glass control judgment.

[0093] Step S403: If the lateral pressure value of the vehicle window glass is between the first preset pressure threshold and the second preset pressure threshold, respond to the vehicle window glass lifting instruction at the initial lifting speed, and the first preset pressure threshold is less than the second preset pressure threshold.

[0094] It should be noted that, in order to improve the flexibility and adaptability of the system, a second preset pressure threshold is set, and the first preset pressure threshold and the second preset pressure threshold together define a safe critical range of pressure values. If the lateral pressure value of the vehicle window glass exceeds the second preset pressure threshold, the system may consider that the vehicle window encounters a larger obstacle or other abnormal conditions, and thus take appropriate protective measures.

[0095] It can be understood that if the side pressure value of the window glass is between the two threshold values, i.e. neither greater than the second preset pressure threshold value nor less than the first preset pressure threshold value, the system considers that the resistance encountered by the window during the lifting process is within an acceptable safety range, in which case the system responds to the lifting instruction according to the initially set lifting speed and continues to lift the window glass.

[0096] In step S404, if the side pressure value of the window glass is not less than the second preset pressure threshold value, the response to the window glass lifting instruction is stopped.

[0097] It can be understood that when it is detected that the foreign object is within the range of the window and the upper edge of the foreign object is below the upper edge of the window glass, if a lifting instruction of the window glass is received at this time and the side pressure value of the window glass is not less than the second preset pressure threshold value, the system will stop executing the lifting instruction of the window glass.

[0098] For example, it is assumed that a child A presses his elbow on the window glass with force out of curiosity or playfulness. This action will cause the window glass to be subjected to a large side pressure, which can be caused by the squeezing of the elbow of the child. If the side pressure value reaches or exceeds the second preset pressure threshold value of the system, the system will consider that the resistance encountered by the window during the lifting process is beyond the acceptable safety range, which can be caused by the presence of the foreign object. In order to avoid damage to the elbow of the child, the system will immediately stop executing the lifting instruction of the window glass.

[0099] Further, after the step S401, the method further comprises:

[0100] when the position relationship is that the lower edge of the foreign object is above the upper edge of the window glass and the window glass control instruction is a lifting instruction of the window glass, lifting the window glass at the regular lifting speed;

[0101] when the preset liftable height is not greater than the preset height threshold value, changing the regular lifting speed to the initial lifting speed.

[0102] It can be understood that when the system detects that all position points of the lower edge of the foreign object are above the upper edge of the window glass and a lifting instruction of the window glass is received at this time, the window glass will be lifted at the regular lifting speed. If during the lifting process, the system predicts that the liftable height of the window glass is not greater than the preset height threshold value, the lifting speed of the window glass will be changed from the regular speed to the slower initial lifting speed.

[0103] For example, assume that the window glass is currently in a half-open state, and user A initiates an instruction to lift the window glass. The system first detects whether there is a foreign object (such as a branch) above the window glass. If the system detects that the lower edge of the foreign object is above the upper edge of the window glass, the window glass will start to lift at a regular speed. However, during the lifting process, the system finds that the window glass can only lift a small distance before contacting the foreign object due to the presence of the foreign object. If the preset liftable height is less than the preset height threshold, the lifting speed of the window glass will automatically slow down from the regular speed to the initial speed to avoid collision or damage due to excessive speed.

[0104] It should be understood that, in order to ensure safety in lifting the window glass at a regular lifting speed, the preset liftable height and the preset height threshold are set, and the preset liftable height needs to be calculated according to the spatial position of the foreign object and the upper edge of the window glass, combined with an appropriate safety space margin. Therefore, before the step of changing the regular lifting speed to the initial lifting speed when the preset liftable height is not greater than the preset height threshold, the method further comprises: calculating the liftable height of each point of the upper edge of the window glass according to the position points of the lower edge of the foreign object, the position points of the upper edge of the foreign object, and the position of the upper edge of the window glass; obtaining the minimum value of the liftable height from the liftable height of each point of the upper edge of the window glass, and subtracting the minimum value of the liftable height from the preset space margin to obtain the preset liftable height.

[0105] It should be noted that the shape of the window glass is usually irregular, and is often designed to be curved, inclined, or with a special contour in order to adapt to the streamlined design and vision requirements of the vehicle. Such irregular shape means that the upper edge of the window glass is not a simple straight line, but a curve composed of multiple points, each point having its own coordinates and height.

[0106] Therefore, when determining whether the window glass can continue to lift and determining the liftable height thereof, the liftable height of each point of the upper edge of the window glass needs to be calculated according to the specific position of each point. In order to ensure the safety of the lifting process of the window glass, the minimum value of the liftable height of each point of the upper edge of the window glass is found from the calculated liftable height, and this minimum value represents the maximum distance that the window glass can safely move during the lifting process.

[0107] After the step S401, the method further comprises:

[0108] when the position relationship is that part of the upper edge of the foreign object is above the upper edge of the vehicle window glass and part of the lower edge of the foreign object is below the upper edge of the vehicle window glass, and the vehicle window glass control instruction is a vehicle window glass lifting instruction, if the vehicle window glass lateral pressure value is less than the first preset pressure threshold, the initial lifting speed is used to respond to the vehicle window glass lifting instruction;

[0109] if the vehicle window glass lateral pressure value is not less than the first preset pressure threshold, the responding to the vehicle window glass lifting instruction is stopped.

[0110] It should be understood that when the vehicle window glass is lifted, if part of the position points of the upper edge of the foreign object are higher than the upper edge of the vehicle window glass, and part of the position points of the lower edge of the foreign object are lower than the upper edge of the vehicle window glass, it means that there is a spatial intersection between the foreign object and the vehicle window glass, i.e. the foreign object may block the lifting of the vehicle window glass. At this time, if the vehicle window glass lateral pressure value is less than the first preset pressure threshold, the system considers that the vehicle window glass can continue to be safely lifted at the initial lifting speed, because the resistance encountered at this time is small and will not cause damage to the vehicle window glass or the vehicle.

[0111] However, if the vehicle window glass lateral pressure value is not less than the first preset pressure threshold, the system will judge that there is a greater risk that the potential foreign object is tightly pressed against the vehicle window glass to cause a certain extrusion. In this case, in order to prevent injury, the system will stop responding to the lifting instruction of the vehicle window glass.

[0112] Exemplarily, if the passenger A stretches his hand out of the window when the vehicle window is not completely closed and the elbow part is located on the edge of the vehicle window, the lifting instruction of the vehicle window glass is issued, at this time, the hand becomes a foreign object in the lifting path of the vehicle window glass. If the system detects that the pressure encountered by the vehicle window glass when trying to lift exceeds the first preset pressure threshold (which usually means that the hand is pressed against the vehicle window glass), it will immediately stop lifting to prevent injury to the hand.

[0113] It should be noted that if the lifting control instruction received by the vehicle is a one-key lifting instruction, the system continues to monitor whether there is a foreign object and whether the vehicle window glass lateral pressure value is greater than the first preset threshold during the lifting of the vehicle window glass to the top. When it is perceived that the vehicle window glass lateral pressure value is greater than the first preset threshold, the system stops the glass lifting action. When it is perceived that the foreign object disappears, the system immediately makes a comprehensive decision to execute the next vehicle window glass control according to the glass liftable height, the glass upper edge position, the vehicle window glass lateral pressure value, etc. calculated by the system.

[0114] The embodiment detects the relationship between the foreign object and the upper edge of the vehicle window glass, obtains the upper and lower edge position points of the foreign object, and compares them with the upper edge of the vehicle window glass. If the upper edge of the foreign object is below and the lifting instruction is issued, the lifting speed or stopping is adjusted according to the lateral pressure value of the vehicle window glass; if the lower edge of the foreign object is above, the vehicle window glass is lifted at a regular speed, and the lifting speed is reduced when the preset lifting height is less than the preset height threshold; when the upper and lower edges of the foreign object are above and below the upper edge of the vehicle window glass respectively, the vehicle window glass is lifted at an initial speed or stopped according to the pressure value, which can effectively prevent the vehicle window glass from pressing the foreign object, thereby preventing damage to the foreign object or the vehicle.

[0115] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as the above embodiment one can be referred to the above introduction, and the subsequent will not be described in detail. On this basis, please refer to Figure 6 , after the step S10, it can further include steps S11-S14:

[0116] In step S11, when the foreign object exists in the vehicle window range and the vehicle window glass control instruction is a vehicle window glass lowering instruction, the degree of pressing of the vehicle window is detected by the bar pressure sensor to obtain the lateral pressure value of the vehicle window glass.

[0117] In step S12, if the lateral pressure value of the vehicle window glass is less than the first preset pressure threshold, the vehicle window glass lowering instruction is responded at a regular lifting speed.

[0118] It can be understood that when the foreign object exists in the vehicle window range and the vehicle window glass receives the lowering instruction, the degree of pressing of the vehicle window glass in the lowering process is monitored by the bar pressure sensor to obtain the lateral pressure value of the vehicle window glass.

[0119] Further, if the lateral pressure value of the vehicle window glass is less than the first preset pressure threshold, the system considers that the pressing force of the foreign object on the vehicle window glass is small, which will not cause damage to the vehicle window or the foreign object, and thus the vehicle window glass lowering instruction is continued to be executed at a regular lifting speed.

[0120] Exemplarily, assuming that the vehicle window is half open, a passenger A slightly sticks a paper cup to the edge of the vehicle window. At this time, the vehicle window glass lowering instruction is received. Since the pressing force of the paper cup in this state on the vehicle window is small, the lateral pressure value of the vehicle window glass detected by the bar pressure sensor is less than the first preset pressure threshold. Therefore, the vehicle window continues to be lowered at a regular lifting speed.

[0121] It should be noted that if the control instruction for lowering the vehicle window glass is a one-key lowering instruction, the system continuously monitors whether the lateral pressure value of the vehicle window glass is greater than the preset pressure threshold during the process of lowering the vehicle window glass to the bottom.

[0122] Step S13, if the side pressure value of the window glass is between the first preset pressure threshold and the second preset pressure threshold, the initial lifting speed is used to respond to the window glass lowering instruction.

[0123] It should be understood that when there is a foreign object in the window range and a control instruction of lowering the window glass is received, if the detected side pressure value of the window glass is between the two preset pressure thresholds, the system considers that the window glass is still in a safe and controllable range although it is pressed to a certain extent. Therefore, the system continues to execute the control instruction of lowering the window glass at the initial lifting speed, ensures that the window glass can be smoothly and safely lowered, and avoids causing excessive impact force to the foreign object. In some cases, if the pressing force comes from the user, responding to the window glass lifting instruction at the initial lifting speed is also a reminder to the user.

[0124] Step S14, if the side pressure value of the window glass is not less than the second preset pressure threshold, the responding to the window glass lowering instruction is stopped.

[0125] It can be understood that if the side pressure value of the window glass reaches or exceeds the second preset pressure threshold, it means that the window glass may encounter a larger resistance during the lowering process, which is likely because the foreign object is stuck in the window.

[0126] For example, the passenger A has his arm close to the window glass in the case of half-open window. If the pressure of the window glass caused by the arm is too large and exceeds the second preset pressure threshold, the window glass will immediately stop lowering to prevent injury to the arm.

[0127] When a foreign object is encountered in the window range and a window glass lowering instruction is received, the embodiment sets different pressure threshold values to determine the range of the side pressure value of the window glass. The system can intelligently determine whether the window glass encounters abnormal resistance during the lowering process, so as to timely stop the lowering, adjust the lowering speed or other corresponding operations, and avoid damage to the passenger, vehicle or foreign object caused by the window sticking to the foreign object.

[0128] In the third embodiment, after the step S10, the method can further include the steps of:

[0129] When there is no foreign object in the window range, the initial lifting speed is changed to a conventional lifting speed, and it is detected whether the foreign object exists in the window range.

[0130] It can be understood that a slower speed is adopted in the starting stage when the system confirms that there is indeed no foreign matter in the window range. Once the safety is confirmed, the system will increase the speed to the regular lifting speed to improve the efficiency of the window glass lifting. However, even if the window has started to lift at the regular speed, the system will still maintain the monitoring of the window range to ensure that there is no sudden situation during the lifting.

[0131] The embodiment responds to the window glass control instruction at the regular lifting speed when there is no foreign matter in the window range, and detects whether there is a foreign matter in the window range, comprehensively and carefully considers the possible sudden situation or failure of the window glass lifting, optimizes the efficiency of the window glass lifting, and through the continuous monitoring of the foreign matter in the window range, the system can discover and respond to any potential safety hazard in the first time, and improves the accuracy and safety of the window glass lifting control.

[0132] It should be noted that the above examples are only used for understanding the present application and do not constitute a limitation on the window glass control method of the present application, and more forms of simple transformation based on this technical concept are within the protection scope of the present application.
