Description

Technical Field

[0001] This invention relates to the field of vehicle window control, and particularly to a vehicle window control method, electronic device, and vehicle. Background Technology

[0002] In vehicles with frameless windows, such as yachts and cars, the absence of frames allows noise to easily enter the cabin, affecting passenger comfort. To prevent noise from entering the vehicle, noise-reducing strips are typically integrated into the vehicle's body. For example, in vehicles with frameless windows, sealing strips are usually embedded in the body, and when the windows are closed, the sealing strips are recessed into the window.

[0003] In vehicles that use frameless windows, the windows are prone to colliding with the noise reduction strips or the vehicle body when the vehicle door needs to be opened. Summary of the Invention

[0029] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that the embodiments of this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the embodiments of this application with unnecessary detail.

[0030] It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] It should also be understood that references to "one embodiment" or "some embodiments" in the specification of embodiments of this application mean that one or more embodiments of this application include the specific features, structures, or characteristics described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized in the description of embodiments of this application. Unless otherwise expressly limited, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in the embodiments of this application in conjunction with the specific content of the technical solution.

[0032] The following is a description of any terms that may be used in this application. These descriptions are not intended to limit the scope of this application.

[0033] Frameless windows are a type of window that can be applied to various types of vehicle doors. The difference between frameless and traditional vehicle windows lies in the fact that the glass in a traditional vehicle window is confined within a complete window frame, moving up and down within that frame. In frameless windows, at least one window frame (especially the top frame) is not present. Therefore, when the vehicle door is open, there is no limiting device at the top of the window. When the vehicle door is closed, the window can press against the vehicle body or other devices installed on the vehicle body, such as receiving cavities or limiting strips, to achieve a seal.

[0034] The following describes a vehicle and a vehicle door according to an embodiment of the vehicle window control method applicable to the present application.

[0035] Figure 1 This is a schematic diagram of a vehicle door according to an embodiment of this application. (Reference) Figure 1 The vehicle door 10 is a vehicle door suitable for automobiles, comprising: a vehicle door body 101, a vehicle window 102, and a handle 103. The vehicle window 102 is connected to the vehicle door body 101, and the handle 103 is mounted on the vehicle door body 101. Specifically, the vehicle door body 101 has a clamping structure (not shown) and a lifting mechanism inside. The clamping structure clamps the vehicle window 102, and the lifting mechanism connected to the clamping structure can control the movement of the vehicle window 102 relative to the retaining cavity 104. The vehicle window 102 can descend into the retaining cavity 104 and be partially or completely retained within the vehicle door body 101. It is easy to understand that, compared with common vehicle doors, the vehicle window 102 of this vehicle door 10 is not limited by a frame, and is therefore a frameless window.

[0036] As is easily understood, a similar vehicle door 10 with a vehicle window 102 can be installed on any vehicle. Figure 1 (Not shown in the image). For example, yachts and low-speed aircraft only need to be appropriately modified to adapt to different vehicle forms. Regardless of the type of vehicle on which it is installed, it does not affect the beneficial effects of the vehicle control method of the embodiments of this application described later.

[0037] by Figure 1 Taking the vehicle door 10 as an example, in order to ensure the airtightness of the vehicle after the vehicle door 10 is closed, a receiving cavity is usually provided on the vehicle body to accommodate the top of the vehicle window 102. After the vehicle door 10 is closed, the vehicle window 102 automatically rises into the receiving cavity to seal the vehicle. In some embodiments, instead of providing a receiving cavity embedded in the vehicle body, a receiving cavity is formed by adding adhesive strips or other sealing devices, which can also produce a similar sealing effect.

[0038] However, the above sealing caused the following problems: (1) When the vehicle door 10 needs to be opened, the top of the vehicle window 102 enters the receiving cavity, so the vehicle door 10 cannot be opened smoothly, or the vehicle window 102 is easily damaged.

[0039] There are generally two scenarios when the vehicle door 10 needs to be opened: one is to pull the handle 103 from the outside to open the vehicle door 10 and enter the vehicle; the other is to leave the vehicle from the inside. In some known technologies, the following solutions are used to address the problems that exist when entering the vehicle.

[0040] When the user touches handle 103, the vehicle window 102 descends a preset distance, leaving the receiving cavity. Before the vehicle window 102 completes its descent, the user cannot open the vehicle door 10 even if they pull handle 103. Handle 103 is only activated after the vehicle window 102 has completed its preset descent. When the user enters the vehicle and closes the vehicle door 10, the vehicle window 102 rises again a preset distance, re-entering the receiving cavity and resealing the vehicle. This prevents the vehicle window 102 from hitting the receiving cavity and preventing the vehicle door 10 from opening.

[0041] However, the aforementioned known technologies have created new problems. Specifically, (2) before the vehicle window 102 completes its descent, the user cannot open the vehicle door 10 even if they keep pulling the handle 103. The continuity of the door opening operation is poor, which affects the user's experience. (3) During the process of the vehicle window 102 automatically rising to close the vehicle, the relative position of the lifting mechanism and the vehicle window 102 may change for various reasons, which may cause the vehicle window 102 to fail to close completely when it rises automatically, thus allowing external noise to enter the vehicle.

[0042] Figure 2 This is a flowchart of a vehicle window control method according to an embodiment of this application.

[0043] refer to Figure 2 To address at least one of the above problems, this application proposes a vehicle window control method applied to a vehicle. The vehicle includes a vehicle body, a vehicle door, a vehicle window installed on the vehicle door, and a lifting mechanism for driving the vehicle window to move. The vehicle body includes a receiving cavity for accommodating the top of the vehicle window, and the lifting mechanism is used to drive the vehicle window to move towards and / or away from the receiving cavity. The method includes:

[0044] S100: Obtain positioning information; positioning information represents the relative position of the terminal with respect to the vehicle;

[0045] S200: Generate control information based on positioning information;

[0046] S300: In response to control information, control the lifting mechanism to change the relative distance between the top of the vehicle window and the receiving cavity.

[0047] By acquiring the location information of the user's terminal, control information is generated to control the vehicle window to leave the receiving cavity. In this way, the vehicle window will descend in advance before the user opens the door, so that it will not hit the receiving cavity or the main body of the vehicle.

[0048] Figure 3 This is a schematic diagram illustrating the acquisition of location information according to an embodiment of this application.

[0049] refer to Figure 3 The above-mentioned vehicle window control method will be explained.

[0050] First, step S100 is executed to acquire location information, which represents the relative position of the terminal to the vehicle. The terminal can be any device capable of emitting signals, such as a mobile phone, tablet, or car key. This allows the vehicle to determine the terminal's position relative to it based on the signals emitted by the terminal.

[0051] Therefore, S100 may include:

[0052] S101: Enable at least one receiving device to receive a wireless signal transmitted by the terminal;

[0053] S102: Obtain at least one attenuation information based on the wireless signal; the attenuation information represents the propagation distance of the wireless signal to the receiving device;

[0054] S103: Calculate and obtain positioning information based on attenuation information.

[0055] For example, the terminal could be an active car key, with an electromagnetic wave signal transmitter and an electromagnetic wave receiver installed in the vehicle. The electromagnetic wave signal transmitter continuously emits electromagnetic wave signals when the vehicle is stationary (e.g., parked, barge, etc.). Upon receiving the electromagnetic wave signals, the active car key emits positioning electromagnetic waves, which the electromagnetic wave receiver then receives and determines the degree of attenuation. The relative distance between the terminal and the vehicle can be calculated based on the attenuation. In some embodiments, for precise positioning, the electromagnetic wave receiver can also determine the propagation direction and waveform changes of the positioning electromagnetic waves, and use this information to determine the location from which the positioning electromagnetic waves were emitted, thereby confirming the current position of the active car key relative to the vehicle and obtaining positioning information.

[0056] In some embodiments, the location of the terminal can also be obtained via a Bluetooth device, such as a mobile phone. Specifically, the RSSI (Received Signal Strength Indication) algorithm can be used for positioning, obtaining the terminal's location by measuring the Bluetooth signal strength received by multiple signal receiving points. In this embodiment, the vehicle includes three or more Bluetooth signal receiving modules. These Bluetooth signal receiving modules have all been pre-calibrated and have established path loss models adapted to the specific vehicle. Multiple Bluetooth signal receiving modules respectively receive the wireless signal (Bluetooth signal) emitted by the mobile phone and calculate the attenuation level of the wireless signal as it propagates to the corresponding Bluetooth signal receiving module to obtain attenuation information. Positioning information is calculated based on the RSSI algorithm by comparing the corresponding attenuation information of different Bluetooth signal receiving modules. Furthermore, to save energy, one of the Bluetooth signal receiving modules can be set as the wake-up module, while the other Bluetooth signal receiving modules are usually in sleep mode. Only the wake-up module remains operational. When the wake-up module receives the wireless signal emitted by the terminal, it wakes up the other Bluetooth signal receiving modules to receive the wireless signal, thereby reducing power consumption.

[0057] For example, in some embodiments, the receiving device includes a primary receiving device and at least one secondary receiving device, such as a Bluetooth receiving module; the positioning information includes relative direction information and relative distance information; therefore, in embodiments with multiple receiving devices, calculating the positioning information based on the attenuation information includes: calculating relative distance information based on the attenuation information corresponding to the primary receiving device; the relative distance information represents the distance of the terminal relative to the primary receiving device; calculating relative direction information based on the attenuation information corresponding to the primary receiving device and the attenuation information corresponding to each secondary receiving device; the relative direction information represents the directional relationship of the terminal relative to the primary receiving device.

[0058] For example, in some embodiments, the main receiving device is positioned in the driver's seat of the vehicle, and secondary receiving devices are positioned at various locations within the vehicle. When the terminal moves towards the vehicle, the attenuation of the wireless signals received by the main and secondary receiving devices differs due to their different positions. Therefore, the directional relationship of the terminal relative to the main receiving device can be calculated based on the differences in attenuation information of the wireless signals received by the main and secondary receiving devices. Furthermore, the approximate propagation time of the wireless signal can be determined using the attenuation information of the wireless signal received by the main receiving device, thereby calculating the distance of the terminal relative to the main receiving device. Once the direction and distance of the terminal are determined, the relative position of the terminal to the main receiving module is also determined.

[0059] In some embodiments, the vehicle is a car, and the car is equipped with multiple area controllers, each with integrated Bluetooth functionality. In this case, the area controller closest to the driver's seat can be designated as the primary receiver. This is because the terminal is held by the driver, who needs to open the vehicle door from the driver's seat; therefore, the driver's seat is used as the point for determining the distance between the vehicle and the terminal. Furthermore, other area controllers in the car can obtain distance information from the area controller closest to the driver's seat and control the vehicle windows of other vehicle doors they control.

[0060] Furthermore, a detection cycle with a specified time can be set, and positioning information can be obtained once in each cycle until the positioning information meets the requirements for generating control information as described later.

[0061] It is readily understood that the embodiments of this application can complete the above-described vehicle window control method using only existing area controllers, without incurring additional costs.

[0062] In S200, control information is generated based on the positioning information. For example, the vehicle has a central controller (area controller). The central controller receives the attenuation information transmitted by the Bluetooth signal receiving module and calculates the positioning information. It then converts the positioning information into control information for controlling the vehicle window according to a pre-designed interface. Alternatively, the vehicle window has a control device including an independent computing unit. This control device receives the positioning information and converts it into control information through a preset algorithm.

[0063] Then, S300 is executed, responding to the control information to control the lifting mechanism, changing the relative distance between the top of the vehicle window and the receiving cavity. That is, based on the content reflected in the control information, the lifting mechanism located at the vehicle door or other positions in the vehicle is controlled, so that the motor or hydraulic device of the lifting mechanism raises or lowers the vehicle window, thereby changing the relative distance between the top of the vehicle window and the receiving cavity.

[0064] Combination Figure 3 The first identification circle 301 and the second identification circle 302 can be divided according to the distance between the terminal and the vehicle 1, thereby dividing the area close to the vehicle 1 into the first area Z1, the second area Z2 and the third area Z3.

[0065] Figure 4 This is a flowchart illustrating the generation of the first control information according to an embodiment of this application.

[0066] Combination Figure 4 S200 may include:

[0067] S201: Obtain the relative distance between the terminal and the vehicle based on the positioning information;

[0068] S202: When the relative distance is less than the first preset value, generate the first control information.

[0069] Specifically, the relative distance between the terminal and the vehicle 1 is calculated based on the positioning information obtained in S100. The relative distance refers to the relative distance between the terminal position and a certain part of the nearest vehicle body. For example, in the embodiment where the vehicle 1 is a vehicle, the user holds the terminal and moves from the direction directly in front of the vehicle towards the direction of the vehicle. At this time, the relative distance between the vehicle and the terminal should be calculated.

[0070] A first recognition circle 301 can be defined using a first preset value. When the positioning information indicates that the relative distance between the terminal and the vehicle 1 is less than the first preset value and the terminal has entered the first recognition circle 301, corresponding first control information can be generated. This causes the lifting mechanism to move the vehicle window so that the relative distance between the top of the vehicle window and the receiving cavity is greater than the first preset distance. Specifically, moving the vehicle window causes the top of the window to completely detach from the receiving cavity, allowing the user to open the vehicle door without obstruction when entering the vehicle 1. Compared with known technologies, since the vehicle window has already descended before the user touches the handle, the user can directly pull the handle to open the vehicle door without waiting for the window to descend. This operation is smooth and convenient, improving the user's sensory experience and avoiding the confusion of why the user has to pull the handle several times to open the door, thus conforming to the user's intuitive experience. In addition, it also increases the speed at which the user enters the vehicle.

[0071] After completing the steps of lowering the vehicle window described above, S203 can also be executed after the user enters the vehicle and closes the vehicle door.

[0072] S203: Control the lifting mechanism to allow the top of the vehicle window to enter the receiving cavity.

[0073] Thus, the vehicle is sealed off via S203.

[0074] In some embodiments, the vehicle door handle is embedded within the vehicle door when inactive, creating a smooth, flat surface that reduces air resistance during vehicle movement. However, this handle typically requires a user touch to pop out, driven by a lifting mechanism built into the vehicle door. In some known technologies, this handle is also used for frameless windows, so the vehicle door opening process can be: ① the user touches the handle; ② the handle rises while the vehicle window descends; ③ the user pulls the handle to open the vehicle door. By matching the handle's rising speed with the vehicle window's descending speed, the vehicle window can be fully lowered after the handle is fully raised.

[0075] However, according to the vehicle window control method of the present application embodiment, the vehicle window completes the position change before the user touches the handle. Therefore, if the solution of raising the handle after touching the handle is used, it will increase the user's waiting time and result in a poor user experience.

[0076] Based on the above problems, this application proposes corresponding solutions.

[0077] Figure 5 This is a flowchart illustrating the generation of the second control information according to an embodiment of this application.

[0078] Combination Figure 5 The S200 may also include:

[0079] S204: Obtain the relative distance between the terminal and the vehicle based on the positioning information;

[0080] S205: When the relative distance is less than the second preset value, generate the second control information.

[0081] Specifically, refer to Figure 3 The second identification circle 302 can be further divided. When the positioning information reflects that the relative distance between the terminal and the vehicle 1 is less than the second preset value and the terminal enters the second identification circle 302, the corresponding second control information can be generated.

[0082] Based on the second control information, the lifting mechanism built into the vehicle door and connected to the handle is controlled to pop the handle out, making the handle protrude relative to the vehicle door. That is, the handle has already popped out before the user touches it, so the user can pull the handle to open the vehicle door and enter the vehicle without waiting.

[0083] Therefore, based on the above embodiments, the door opening method of this application embodiment is: ① the terminal approaches the vehicle; ② the vehicle window automatically lowers and the handle automatically pops out; ③ the user directly pulls the handle to open the vehicle door.

[0084] Furthermore, to address situations where a user's terminal approaches the vehicle and attempts to open the door, this application also proposes:

[0085] After controlling the handle in response to the second control information to make the handle protrude relative to the vehicle door, the method includes: when no door opening action is detected within a preset time period, controlling the handle to retract so that the handle does not protrude relative to the vehicle door, and / or controlling the lifting mechanism to allow the top of the vehicle window to enter the receiving cavity.

[0086] That is, even if the terminal is still within the first recognition circle 301 or the second recognition circle 302, as long as there is no door opening action within a preset time, the handle will be retracted and the vehicle window will be raised. Correspondingly, when the terminal is within the first recognition circle 301 but outside the second recognition circle 302, the lifting mechanism will be controlled to raise the vehicle window; or when the range of the second recognition circle 302 is larger than the first recognition circle 301, and the terminal is within the second recognition circle 302 but outside the first recognition circle 301, the lifting mechanism will be controlled to retract the handle.

[0087] In some embodiments, the first identification circle 301 and the second identification circle 302 are centered on the area controller located at the driver's seat of the vehicle.

[0088] Figure 6 This is a flowchart illustrating the generation of the third control information in an embodiment of this application.

[0089] refer to Figure 6 For situations where a user carrying a terminal passes through a vehicle, or a user leaves a vehicle and moves away from the vehicle, this application also proposes a corresponding solution. Specifically, the control information includes third control information, which is generated based on the positioning information, including:

[0090] S206: Obtain the relative distance between the terminal and the vehicle based on the positioning information;

[0091] S207: When the relative distance is greater than the third preset value, generate the third control information;

[0092] That is, in Figure 3 Based on this, a third identification circle (not shown in the figure) is set up. When the terminal leaves the third identification circle, the corresponding third control information is generated.

[0093] Based on the third control information, S300: In response to the control information, control the lifting mechanism to adjust the relative distance between the top of the vehicle window and the receiving cavity, including: In response to the third control information, control the lifting mechanism to allow the top of the vehicle window to enter the receiving cavity.

[0094] When the distance between the terminal and the vehicle exceeds a third threshold, the lifting mechanism moves the vehicle window to close, thus sealing the vehicle and ensuring safety inside. Therefore, whether the user passes by the vehicle, causing the distance between the vehicle and the terminal to fall below the first threshold and the vehicle window to lower, or the user leaves the vehicle, the vehicle window automatically rises, improving vehicle safety.

[0095] Furthermore, some embodiments of this application can also solve the problem that during the process of automatically raising and closing the vehicle window, the relative position of the lifting mechanism and the vehicle window may change due to various reasons, making it impossible for the vehicle window to close completely when it automatically rises, thus allowing external noise to enter the vehicle.

[0096] Such problems arise in ways such as the following.

[0097] On the one hand, to ensure safety, many vehicle windows using motorized lifting mechanisms have anti-pinch functions. Specifically, when the vehicle window encounters resistance during ascent, it automatically lowers a certain distance to allow the trapped object to be removed, and then automatically rises again. During this automatic descent after encountering resistance, the relative position of the vehicle window and the lifting mechanism controlling it often changes. For conventional vehicle windows with frames, the top limit frame ensures that the window can be completely closed as long as it rises to the top when closing, preventing the motor from driving the lifting mechanism further. However, for frameless windows, there is no corresponding limit frame when the vehicle door is open, so the automatic rise usually only goes up a preset distance before stopping. Therefore, due to the change in the relative position of the lifting mechanism and the vehicle window, the automatic rise of the window cannot be completely sealed.

[0098] On the other hand, the cavities set on the main body of the vehicle are easily worn parts such as rubber strips and plastic anti-slip grooves. When such cavities wear out, the vehicle windows may not be able to completely seal the vehicle when they rise to the factory-set preset height.

[0099] Figure 7 This is a flowchart illustrating the movable range of the updated vehicle window according to an embodiment of this application.

[0100] refer to Figure 7 Therefore, the control information vehicle window control method of this application, in S300: responding to the control information to control the lifting mechanism to change the relative distance between the top of the vehicle window and the receiving cavity, further includes:

[0101] S401: Obtain the first zero point of the vehicle window; the first zero point represents the lowest descent position of the vehicle window;

[0102] S402: Obtain the second zero point of the vehicle window; the second zero point represents the highest rising position of the vehicle window;

[0103] S403: Update the movable range of the vehicle window based on the first zero point.

[0104] Through the above steps, the positional relationship between the vehicle window and the lifting mechanism can be re-determined based on the first zero point and the second zero point, thereby calibrating the vehicle window and eliminating the errors caused by wear of the receiving cavity or changes in the relative position of the vehicle window and the lifting mechanism. This allows the vehicle window to be raised to a preset position and close the vehicle when it is automatically raised, based on the movable range of the vehicle window.

[0105] Specifically, S401 may include: S404: In response to the trigger state, control the lifting mechanism to drive the vehicle window to move away from the receiving cavity until the lifting mechanism can no longer drive the vehicle window to move, and set the position of the vehicle window to the lowest descending position.

[0106] S405: Set the lowest position to the first zero point.

[0107] Specifically, after the handle is pulled and the vehicle door is opened, an automatic calibration is performed, causing the lifting mechanism to drive the vehicle window down until it reaches a point where the lifting mechanism can no longer drive the vehicle window down. This point is taken as the first zero point. It is easy to understand that since the length, width, and height of the vehicle window are fixed, the current position of the top of the vehicle window can be determined through S404.

[0108] In some embodiments, the vehicle further includes a vehicle window control button, which controls the lifting mechanism; obtaining a second zero point of the vehicle window includes: when the lifting mechanism moves the vehicle window toward the receiving cavity in response to the vehicle window control button and cannot move further into the receiving cavity, setting the position of the vehicle window to the highest rising position; setting the highest rising position as the second zero point.

[0109] That is, when the user manually controls the control button of the vehicle window inside the vehicle and manipulates the vehicle window to rise to the position of the receiving cavity and abut against the receiving cavity, so that the vehicle window can no longer be raised under the drive of the lifting device, this position is taken as the second zero point.

[0110] Although the above embodiments mention that the terminal is a mobile phone and that the mobile phone is used to transmit Bluetooth signals, other terminals that can install Bluetooth components, such as tablet computers or portable Bluetooth transmitters, can also achieve the same technical effect without affecting the realization of the beneficial effects of this application.

[0111] Although the above embodiments mention using the RSSI algorithm in conjunction with Bluetooth technology and a Bluetooth receiver module to obtain attenuation information, it is clear that other wireless signal technologies, such as radar signals, infrared signals, or Zigbee technology, and by installing a receiver module corresponding to the wireless signal on the vehicle, can also use the RSSI algorithm to obtain attenuation information and thus determine the terminal location. The choice of wireless signal type does not affect the realization of the beneficial effects of this application.

[0112] Although the above embodiments mention that the relative distance between the computing terminal and the vehicle refers to the relative distance between the computing terminal and a certain part of the nearest vehicle body, in some embodiments, the center of mass of the vehicle or the center of the space it occupies can also be regarded as a point, and the relative distance between the computing terminal and that point, or other reasonable methods can be used to define the relative distance to achieve the subsequent steps of the embodiments of this application. However, it should be understood that the relative distance between the computing terminal and a certain part of the nearest vehicle body can improve the user experience. For vehicles that are long and narrow, it can prevent the vehicle window from lowering when the terminal is still some distance away from the vehicle door, and is therefore a preferred embodiment.

[0113] Although the accompanying drawings show that the first identification circle 301 surrounds the second identification circle 302, it is clear that the relationship between the first and second preset values ​​used to distinguish the first and second identification circles 301 is not limited. The first preset value can be greater than, less than, or equal to the second preset value. Therefore, the first identification circle 301 can also be surrounded by the second identification circle 302, or the first identification circle 301 and the second identification circle 302 can be equivalent. Those skilled in the art can freely set these values ​​according to their needs. Furthermore, for ease of illustration, the first and second identification circles 301 and 302 are depicted as ellipses. Clearly, the first and second identification circles 301 are not limited; they can be circular or vary according to the shape of the vehicle.

[0114] While the above embodiments mention obtaining a first zero point by automatically calibrating the vehicle window when the door handle is pulled, and a second zero point by the user manually operating the vehicle window to press against the receiving cavity, the embodiments are not limited to these. In some embodiments, by setting multiple etched lines on the vehicle window that reflect light of a specific wavelength, such as ultraviolet light, and placing a camera in the vehicle door, the positional change of the vehicle window is determined by identifying changes in the position of the etched lines, thereby obtaining the first or second zero point.

[0115] Although the above embodiments mention that the handle is lifted by a lifting mechanism to protrude from the vehicle door, or that the lifting mechanism drives the handle and changes the lifted state of the handle protruding from the door, the embodiments are not limited to these. In some embodiments, such operations can be performed without a lifting mechanism. For example, the handle may have a gas spring inside, and a slide rail may be provided below the handle. When the gas spring is inflated, the handle moves along the slide rail and changes its posture, causing the handle to protrude relative to the vehicle door.

[0116] This application also proposes an electronic device, which includes a processor and / or a memory. The processor is used to execute the vehicle window control method described above, and the memory stores the vehicle window control method described above. This electronic device can be installed in various vehicles and control the vehicle windows through various signal buses of the vehicle or other wired / wireless communication methods. Alternatively, the electronic device can be a server that connects to any computing device on the vehicle via a network and remotely controls the vehicle through the network device.

[0117] The vehicle window control method of this application embodiment can also be set in a vehicle, the vehicle including: a vehicle body; at least one vehicle door installed in the vehicle body; a frameless, liftable vehicle window installed in at least one vehicle door; at least one receiving device for receiving wireless signals emitted from a terminal and determining the relative position of the terminal and the vehicle based on the wireless signals; wherein, one of the receiving devices is disposed in the driver's seat of the vehicle; at least one receiving cavity disposed in the vehicle body for accommodating the top of the vehicle window; at least one lifting mechanism connected to the vehicle window for driving the vehicle window to move toward and / or away from the receiving cavity; and a control unit for controlling the lifting mechanism according to the relative position of the terminal and the vehicle to change the relative distance between the top of the vehicle window and the receiving cavity.

[0118] In some embodiments, the vehicle described above may also perform any of the vehicle window control methods described in the embodiments of this application.

[0119] Furthermore, the aforementioned vehicle has three Zone Control Units (ZCUs), which integrate vehicle electronics, power control, and Bluetooth receiver modules. By receiving positioning signals from the receiving terminal, the Zone Control Unit obtains the relative positional relationship and controls the raising and lowering of the vehicle windows through multiple lifting mechanisms installed within the vehicle. The aforementioned receiving device can be integrated into the zone sensors, for example, as a Bluetooth receiver module. All of the above-described vehicle window control methods can be implemented using existing components within the Zone Control Unit, without requiring additional control devices or sensors.

[0120] In some embodiments, the receiving device may also be a separate Bluetooth receiving module, for example, an independent Bluetooth receiving module may be provided at the rear end and on each side of the vehicle.

[0121] Furthermore, this application also proposes a computer-readable storage medium, which includes volatile or non-volatile, removable or non-removable media implemented in any method or technology for storing information (such as computer-readable instructions, data structures, computer program modules, or other data). Computer-readable storage media include, but are not limited to, RAM (Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), flash memory or other memory technologies, CD-ROM (Compact Disc Read-Only Memory), DVD or other optical disc storage, magnetic cartridges, magnetic tapes, disk storage or other magnetic storage devices, or any other medium that can be used to store desired information and is accessible by a computer. The carrier window control method of this application is stored on a computer-readable storage medium.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
