Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a method, device, equipment and computer-readable storage medium for controlling vehicle windows. Background Technology

[0002] During the closing of a car door, the rapid change in air pressure inside the vehicle can cause a feeling of pressure in the ears for passengers. This phenomenon typically occurs when the vehicle is stationary and the windows are closed. When the door is closed, the air pressure inside the vehicle rises rapidly and cannot escape in time, causing discomfort to the ears. How to effectively avoid this ear pressure sensation during door closing remains a pressing technical challenge. Summary of the Invention

[0003] One objective of this application is to provide a method for controlling a vehicle window to solve the problem of pressure sensation during the closing process of a vehicle door; another objective is to provide a control device for a vehicle window; a third objective is to provide a control equipment for a vehicle window; a fourth objective is to provide a computer-readable storage medium; and a fifth objective is to provide a computer program product.

[0004] The technical solution of this application embodiment is implemented as follows: This application provides a method for controlling a vehicle window, including: in response to detecting that a target door is closing, controlling the opening of the vehicle window according to the movement state of the valve plate of the vehicle pressure relief valve.

[0005] Based on the above technical means, by detecting whether the target car door is closing and combining the movement state of the valve plate of the vehicle's pressure relief valve, it is determined whether the car window needs to be opened, thereby achieving active control of changes in air pressure inside the car, effectively alleviating the problem of pressure on the ears when the door is closed, and improving ride comfort.

[0006] In some embodiments, a single vehicle pressure relief valve is provided inside the vehicle; the valve plate movement state of the vehicle pressure relief valve includes: valve plate opening degree or valve plate opening speed; controlling the opening of the vehicle window according to the valve plate movement state of the vehicle pressure relief valve includes at least one of the following: if the valve plate opening degree of the vehicle pressure relief valve is greater than a preset opening degree threshold corresponding to the target window, controlling the opening of the target window and / or non-target window according to a first preset strategy, each window individually corresponds to a preset opening threshold, the preset opening threshold is set according to the positional relationship of the target door, window, and pressure relief valve; if the valve plate opening speed of the vehicle pressure relief valve is greater than a preset speed threshold corresponding to the target window, controlling the opening of the target window and / or non-target window according to a first preset strategy, each window individually corresponds to a preset speed threshold, the preset speed threshold is set according to the positional relationship of the target door, window, and pressure relief valve.

[0007] Based on the above technical means, compared with a single fixed threshold, the multi-threshold dynamic judgment method improves robustness, and is especially suitable for complex working conditions under different door closing conditions.

[0008] In some embodiments, a vehicle pressure relief valve is individually provided near each vehicle door; the valve plate movement state of the vehicle pressure relief valve includes: valve plate opening degree or valve plate opening speed; controlling the opening of the vehicle window according to the valve plate movement state of the vehicle pressure relief valve includes at least one of the following: if the valve plate opening degree of the target vehicle pressure relief valve is greater than a preset opening degree threshold, controlling the opening of the target window and / or non-target window according to a first preset strategy, and a target window is provided on the door where the target vehicle pressure relief valve is located; if the valve plate opening speed of the target vehicle pressure relief valve is greater than a preset speed threshold, controlling the opening of the target window and / or non-target window according to a first preset strategy, and a target window is provided on the door where the target vehicle pressure relief valve is located.

[0009] Based on the aforementioned technical means, by equipping each car door with an independent vehicle pressure relief valve and controlling the windows based on the movement state of their valve plates, more granular air pressure management can be achieved, ensuring that each window can respond quickly and adjust the pressure inside the vehicle, thereby improving driving and riding comfort.

[0010] In some embodiments, the first preset strategy includes at least one of the following: controlling the target window to open; if the number of target windows is greater than 2, controlling the target windows to open simultaneously; if the number of target windows is greater than 2, controlling the target windows to open simultaneously according to the second preset strategy; if the number of target windows is greater than 2, controlling the target windows to open sequentially according to a preset order; and controlling the target window and / or non-target windows to open based on the detection results of objects next to the target window.

[0011] Based on the aforementioned technical means, the opening methods of multiple car windows can be flexibly controlled through various preset strategies. This can optimize the air pressure release path in different scenarios, reduce unnecessary energy consumption and interference, and meet user needs at the same time.

[0012] In some embodiments, the preset sequence includes at least one of the following: a preset opening threshold from large to small; a preset speed threshold from large to small; or a distance from the target door from near to far.

[0013] Based on the aforementioned technical means, by rationally prioritizing the opening of car windows, the optimal air pressure release path can be ensured, allowing the air pressure inside the car to reach equilibrium more quickly, thereby reducing the occurrence of ear pressure sensation.

[0014] In some embodiments, the second preset strategy includes at least one of the following: controlling a target window that meets the first condition to open by a first descent distance, and controlling a target window that does not meet the first condition to open by a second descent distance, wherein the second descent distance is less than the first descent distance; the first condition includes at least one of the following: the target window is installed on the target door, and there is a target object next to the target window.

[0015] Based on the aforementioned technical methods, by setting different opening distances, it is possible to ensure effective air pressure release while avoiding excessive window opening, reducing wind noise and energy waste, and improving the system's economy and comfort. In particular, for windows close to the human body, the opening range can be appropriately reduced to prevent discomfort to passengers.

[0016] In some embodiments, based on the detection result of an object next to the target window, controlling the opening of the target window and / or non-target windows includes at least one of the following: if no target object is detected next to the target window, controlling the target window to open; if a first type of target object is detected next to the target window, controlling at least one non-target window to open; if a second type of target object is detected next to the target window, controlling the target window to open; if no target object is detected next to any of the windows, controlling all windows to open; if a target object is detected next to all of the windows, controlling the sunroof to open.

[0017] Based on the aforementioned technologies, by combining environmental perception information with window control logic, more intelligent air pressure management can be achieved. For example, selecting a non-target window to open when a passenger is detected can avoid directly disturbing the passenger area and enhance the user experience. The sunroof, as an alternative solution, can also provide an additional air pressure release path when necessary.

[0018] In some embodiments, detecting that a target door is closing includes at least one of the following: detecting that the velocity of the target door toward the closing direction is greater than a closing acceleration threshold; detecting that the acceleration of the target door toward the closing direction is greater than a closing acceleration threshold; or detecting that the target door is subjected to a force toward the closing direction greater than a closing force.

[0019] Based on the aforementioned technical means, by detecting the motion parameters during the door closing process from multiple dimensions, the closing action can be identified more accurately, avoiding false triggering or missed triggering and improving accuracy.

[0020] In some embodiments, the method further includes at least one of the following: controlling the opening speed of the window based on the closing force of the target vehicle door, wherein the opening speed and closing force are positively correlated; controlling the opening speed of the window based on the closing acceleration of the target vehicle door, wherein the opening speed and closing acceleration are positively correlated; controlling the opening speed of the window based on the closing speed of the target vehicle door, wherein the opening speed and closing speed are positively correlated; controlling the opening speed of the window based on the valve opening speed, wherein the opening speed and valve opening speed are positively correlated; controlling the opening distance of the window based on the closing force of the target vehicle door, wherein the opening distance and closing force are positively correlated; controlling the opening distance of the window based on the closing acceleration of the target vehicle door, wherein the opening distance and closing acceleration are positively correlated; controlling the opening distance of the window based on the closing speed of the target vehicle door, wherein the opening distance and closing speed are positively correlated; and controlling the opening distance of the window based on the valve opening speed, wherein the opening distance and valve opening speed are positively correlated.

[0021] By establishing a positive correlation between window opening parameters such as speed and distance and door closing parameters using the aforementioned technical methods, more adaptive air pressure balance control can be achieved. This dynamic adjustment mechanism can respond accordingly to different door closing behaviors, improving control efficiency and user satisfaction.

[0022] This application provides a window control device for use in a vehicle, including: a control unit for controlling the window to open according to the valve plate movement state of the vehicle pressure relief valve in response to detecting that a target door is closing.

[0023] This application provides a vehicle window control device, including: a memory for storing computer-executable instructions or computer programs; and a processor for executing the computer-executable instructions or computer programs stored in the memory to implement the method provided in this application.

[0024] This application provides a computer-readable storage medium storing a computer program or computer-executable instructions for implementing the method provided in this application when executed by a processor.

[0025] This application provides a computer program product, including a computer program or computer executable instructions, which, when executed by a processor, implement the method provided in this application.

[0026] The embodiments of this application have the following beneficial effects: Based on the movement state of the valve plate of the vehicle's pressure relief valve, the window is actively opened, thereby releasing the excessive air pressure generated in the cabin due to the door closing in a timely manner, avoiding the ear pressure sensation for the occupants. This application can also control the opening of target windows and / or non-target windows based on a first preset strategy. Furthermore, this application can control the target window to open at different descent distances based on at least one of the window's position and the distribution of occupants inside the vehicle, ensuring air pressure balance while reducing unnecessary glass descent, thus balancing comfort and energy efficiency.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The above are merely embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.

[0030] In modern automotive design, maintaining cabin air pressure balance is a crucial technical issue. Especially during door closure, the rapid pressure change inside the vehicle can cause ear pressure and discomfort for passengers. This phenomenon typically occurs when the vehicle is stationary and the windows are closed; when the doors are closed, the air pressure inside the vehicle rises rapidly and cannot escape in time, thus causing ear discomfort.

[0031] Therefore, embodiments of this application provide a method, device, equipment, and computer-readable storage medium for controlling vehicle windows. Embodiments of this application actively control the opening of vehicle windows by controlling the movement of the vehicle's pressure relief valve, thereby achieving cabin pressure balance, reducing pressure discomfort, effectively alleviating discomfort caused by sudden pressure changes during door closing, and improving driving and riding comfort.

[0032] Before proceeding with a detailed explanation of the specific implementation methods, some of the technical terms used in this application are explained as follows: 1) Vehicle pressure relief valve: A device used to balance the air pressure difference between the inside and outside of the vehicle cabin. It has an adjustable valve plate inside. When there is a pressure difference between the inside and outside of the cabin, the valve plate will open accordingly to release the excessive internal air pressure.

[0033] 2) Valve plate movement status: This refers to the degree or speed of opening of the valve plate inside the pressure relief valve, specifically including the valve plate opening degree and valve plate opening speed. This status reflects the vehicle's pressure relief valve's response to the air pressure inside the cabin and is an important basis for determining whether it is necessary to trigger the opening of the windows.

[0034] 3) Ear pressure sensation: This refers to the subjective feeling of pressure on the eardrum caused by the rapid increase in air pressure inside the vehicle when the door is closed. It is mainly caused by excessive force when closing the door and the inability to release the air pressure in time.

[0035] 4) First preset strategy: refers to a set of rules that the controller decides how to control the opening of the window in response to the detection that the target door is closing.

[0036] 5) Preset opening threshold / preset speed threshold: These are parameter values ​​set based on the positional relationships of different doors, windows, and vehicle pressure relief valves. When the actual opening degree or actual opening speed of the vehicle pressure relief valve exceeds the corresponding threshold, the controller will determine that the air pressure inside the vehicle is close to or has reached the pressure relief valve's critical point, and control the windows to open accordingly.

[0037] 6) Target object: the driver and passengers inside the vehicle. The controller can select whether to open the target window and / or non-target window based on the presence or absence of the target object and its type (such as type 1 or type 2).

[0038] 7) Closing Acceleration / Closing Speed / Closing Force: These are physical quantities describing the motion state of a car door during closing. Closing acceleration represents the magnitude of the acceleration during the closing process, closing speed represents the magnitude of the linear velocity during the closing process, and closing force represents the magnitude of the external force applied to the door. These parameters can be used to further optimize the speed or distance of the window opening to match the closing force.

[0039] 8) Second preset strategy: This is a more refined control strategy based on the first preset strategy.

[0040] This application monitors the movement of the valve plate of the vehicle's pressure relief valve and dynamically controls the opening of the windows accordingly, thereby actively regulating the air pressure inside the vehicle and preventing the pressure sensation caused by closing the doors. Compared to existing technologies that rely on enlarging the area of ​​the pressure relief hole or changing the door structure, this application provides a technical means to suppress the pressure sensation without hardware modification, offering greater flexibility and applicability. A more detailed description will follow with specific implementation methods.

[0041] This application provides a method for controlling vehicle windows, which can be executed by a controller such as a vehicle body domain controller. The following description focuses on the controller as the executing entity. Figure 1 This is a flowchart illustrating a method for controlling a vehicle window according to an embodiment of this application. The method includes: S101, in response to detecting that the target door is closing, controls the window to open according to the movement state of the valve plate of the vehicle pressure relief valve.

[0042] In this embodiment, the vehicle pressure relief valve is used to balance the air pressure inside the vehicle's cabin. Exemplarily, the vehicle pressure relief valve is a device used to regulate the pressure difference between the inside and outside of the cabin; it is also called a pressure balancing valve, pressure valve, or air pressure balancing port. Vehicle pressure relief valves are typically integrated into the vehicle body, such as the trunk side panel or door sealing structure. The vehicle cabin is a relatively sealed space, and the vehicle pressure relief valve achieves air pressure conduction through the mechanical opening and closing of a valve plate. For example, when the air pressure inside the cabin increases, the valve plate automatically opens under the action of internal air pressure, expelling excess air from the cabin and reducing the air pressure inside the vehicle.

[0043] In this embodiment, the controller can acquire the movement state of the valve plate of the vehicle's pressure relief valve through a data acquisition device. The movement state is used to indicate the opening and closing angle of the valve plate, or to indicate the opening and closing speed of the valve plate. For example, the data acquisition device can be a sensor used to acquire the movement state of the valve plate, including but not limited to angle sensors, Hall effect displacement sensors, photoelectric sensors, potentiometer-type displacement sensors, etc. Taking an angle sensor as an example, the angle sensor is connected to the rotation shaft of the valve plate of the vehicle's pressure relief valve, and acquires the valve plate opening degree and / or valve plate opening speed by detecting the rotation angle of the valve plate. Here, the valve plate opening degree can be understood as the opening and closing angle of the valve plate.

[0044] In this embodiment, in response to detecting that a target door is closing, the controller can acquire the valve plate movement state of the vehicle's pressure relief valve from the acquisition device. For example, the controller can detect that a target door is closing by data collected from sensors installed in the vehicle. These sensors may be, for example, at least one of a door contact sensor installed on the target door or an angle sensor connected to the hinge axis of the target door. For instance, based on the data collected by the sensors, the controller determines that a target door is closing when at least one of the following conditions is met: the speed of the target door in the closing direction is greater than a closing speed threshold; the acceleration of the target door in the closing direction is greater than a closing acceleration threshold; and the force acting on the target door in the closing direction is greater than a closing force.

[0045] The closing speed threshold, closing acceleration threshold, and closing force threshold are all pre-calibrated based on the structural parameters of the target door, such as door weight, hinge moment of inertia, sealing resistance, and the overall vehicle cabin air pressure regulation requirements, and can adapt to the judgment requirements of different door closing scenarios. The speed and acceleration data of the target door in the closing direction can be collected and calculated by an angle sensor or Hall sensor connected to the hinge axis of the target door. The force data of the target door in the closing direction can be collected by the lock body torque sensor, the door force detection module, or the load sensor of the electric door drive motor.

[0046] In this embodiment, the controller can control the opening of at least one of the multiple windows included in the vehicle based on the movement state of the valve plate of the vehicle's pressure relief valve. For example, the vehicle includes a left front window, a right front window, a left rear window, a right rear window, and a sunroof; the controller controls the opening of at least one of these five windows based on the movement state of the valve plate of the vehicle's pressure relief valve. The target door is at least one of the multiple doors included in the vehicle. For example, the target door is at least one of the left front door, right front door, left rear door, and right rear door included in the vehicle.

[0047] The window control method provided in this application dynamically controls the opening of the window based on the movement state of the valve plate of the vehicle pressure relief valve when the target door is detected to be closing, thereby reducing the air pressure inside the vehicle and preventing the problem of pressure on the ears caused by closing the door.

[0048] In some embodiments, the controller can control the window opening parameters based on the closing strength of the target door, wherein the opening parameters include opening speed and opening distance. A greater closing strength results in a faster window opening speed; a smaller closing strength results in a slower window opening speed. A greater closing strength also results in a longer window opening distance; a smaller closing strength results in a shorter window opening distance. In other words, this application can control the window opening speed and / or opening distance to be adapted to the closing strength of the target door.

[0049] For example, the controller controls the window opening speed based on the closing force of the target door, with a positive correlation between opening speed and closing force. That is, the greater the closing force of the target door, the faster the window opens; the smaller the closing force, the slower the window opens. For instance, the controller obtains the actual closing force of the target door through sensor data and determines the actual window opening speed according to a preset mapping rule between closing force and opening speed. This allows the window opening speed to be matched to the door closing force, ensuring that when the door closes with a large force and the cabin pressure rises rapidly, the window can open quickly to achieve rapid depressurization. When the door closes with a small force, the window opens smoothly, balancing depressurization effectiveness and passenger comfort.

[0050] For example, the controller controls the opening speed of the car window based on the closing acceleration of the target door, and the opening speed and closing acceleration are positively correlated. That is, the greater the closing acceleration of the target door, the faster the window opens; the smaller the closing acceleration of the target door, the slower the window opens. For instance, the controller obtains the actual closing acceleration of the target door based on data collected by sensors, and determines the actual opening speed of the window according to the mapping rule between closing acceleration and opening speed.

[0051] For example, the controller controls the opening speed of the car window based on the closing speed of the target door, and the opening speed and closing speed are positively correlated. That is, the faster the target door closes, the faster the window opens; the slower the target door closes, the slower the window opens. For instance, the controller can obtain the actual closing speed of the target door based on data collected by sensors, and determine the actual opening speed of the window according to the mapping rule between closing and opening speeds.

[0052] A high closing speed or acceleration indicates a rapid door closure, causing a sudden pressure difference in the cabin air and potentially resulting in a harsh closing noise. In this case, quickly opening the windows instantly opens the airflow channel between the cabin and the outside, rapidly releasing the high pressure. This suppresses noise from the high pressure difference at its source, ensuring the noise level remains within an acceptable range and improving the door closing experience. A low closing speed or acceleration indicates a smooth door closure, with the cabin air pressure rising slowly without a sudden high-pressure impact. This corresponds to slowly opening the windows, satisfying the pressure relief requirement without creating a strong airflow that blows directly onto the occupants.

[0053] For example, the controller controls the window opening speed based on the valve opening speed, and the opening speed and window opening speed are positively correlated. That is, the faster the valve opens, the faster the window opens; the slower the valve opens, the slower the window opens. For instance, the controller can obtain the valve opening speed based on data collected by sensors and determine the actual window opening speed according to the mapping rule between the opening speed and window opening speed.

[0054] For example, the controller adjusts the window opening distance based on the closing force of the target door, with a positive correlation between opening distance and closing force. That is, a greater closing force of the target door results in a greater window opening distance, and a smaller closing force results in a smaller window opening distance. For instance, the controller obtains the actual closing force of the target door based on sensor data and determines the actual window opening distance according to the mapping rule between closing force and opening distance. This ensures that the window opening distance matches the door closing force, guaranteeing that a greater door closing force results in a larger window opening distance for rapid pressure relief, while a smaller door opening distance results in a smaller window opening distance to balance pressure relief effectiveness and passenger comfort.

[0055] For example, the controller controls the window opening distance based on the closing acceleration of the target door, and the opening distance is positively correlated with the closing acceleration. That is, the greater the closing acceleration of the target door, the greater the window opening distance; the smaller the closing acceleration of the target door, the smaller the window opening distance. For instance, the controller obtains the actual closing acceleration of the target door based on data collected by sensors, and determines the actual window opening distance according to the mapping rule between closing acceleration and opening distance.

[0056] For example, the controller controls the window opening distance based on the closing speed of the target door, and the opening distance is positively correlated with the closing speed. That is, the faster the target door closes, the greater the window opening distance; the slower the target door closes, the smaller the window opening distance. For instance, the controller obtains the actual closing speed of the target door based on data collected by sensors, and determines the actual opening speed of the window according to the mapping rule between closing and opening speeds.

[0057] A high closing speed or acceleration indicates a rapid door closing action. In this case, the window opens a larger distance, instantly opening the airflow channel between the cabin and the outside, quickly releasing high pressure. A low closing speed or acceleration indicates a smooth door closing action. In this case, the window opens a smaller distance, which meets the pressure relief needs without creating a strong airflow that blows directly onto the occupants due to an excessively large window opening.

[0058] For example, the controller controls the opening distance of the window based on the valve opening speed, and the opening distance is positively correlated with the opening speed. That is, the faster the valve opens, the greater the opening distance of the window; the slower the valve opens, the smaller the opening distance of the window. For instance, the controller can obtain the valve opening speed based on data collected by sensors, and determine the actual opening distance of the window according to the mapping rule between the opening speed and the opening distance. The aforementioned sensors can be one or more of the following: angle sensors, Hall effect displacement sensors, photoelectric sensors, and potentiometer-type displacement sensors.

[0059] The following describes several possible ways to control the opening of the car windows based on the movement state of the valve plate of the vehicle's pressure relief valve.

[0060] In some embodiments, a single vehicle pressure relief valve is provided inside the vehicle, and the valve plate movement state of the vehicle pressure relief valve includes: valve plate opening degree or valve plate opening speed. The controller can control the opening of the vehicle window based on the valve plate opening degree and / or valve plate opening speed.

[0061] For example, each window corresponds to a preset opening threshold. Taking a vehicle with a left front window, left rear window, right front window, and right rear window as an example, each of these four windows corresponds to a preset opening threshold. For instance, the left front window corresponds to preset opening threshold A, the left rear window corresponds to preset opening threshold B, the right front window corresponds to preset opening threshold C, and the right rear window corresponds to preset opening threshold D. These four preset opening thresholds are either different from each other or partially the same. For example, preset opening threshold A is 40°, preset opening threshold B is 44°, preset opening threshold C is 40°, and preset opening threshold D is 45°.

[0062] The preset opening threshold for each window is set based on the positional relationship between the target door, window, and vehicle pressure relief valve. For example, the preset opening threshold for each window is a pre-set baseline value used to determine whether the current vehicle pressure relief valve is in a critical state that may trigger a pressure sensation. The preset opening threshold for each window is closely related to the spatial position between the target door, window, and vehicle pressure relief valve, and is pre-calibrated.

[0063] In this embodiment, if the valve opening degree of the vehicle's pressure relief valve is greater than a preset opening degree threshold corresponding to the target window, the target window and / or non-target window are controlled to open according to a first preset strategy. A target window is a window whose preset opening degree threshold is less than or equal to the valve opening degree. In other words, if the valve opening degree of the vehicle's pressure relief valve is greater than the preset opening degree threshold of a window, then that window is a target window. A non-target window is a window whose preset opening degree threshold is greater than the valve opening degree. In other words, if the valve opening degree of the vehicle's pressure relief valve is less than or equal to the preset opening degree threshold of a window, then that window is a non-target window. Taking the preset opening degree threshold mentioned above as an example, if the valve opening degree is 43°, then the left front window and right front window are target windows, and the left rear window and right rear window are non-target windows. That is, if there is a target window whose preset opening degree threshold is less than or equal to the valve opening degree, the controller opens the target window and / or non-target window based on the first preset strategy. The first preset strategy will be described below with reference to specific embodiments, and will not be elaborated here.

[0064] For example, each window corresponds to a preset speed threshold. Taking a vehicle with a left front window, left rear window, right front window, and right rear window as an example, each of these four windows corresponds to a preset speed threshold. For example, the preset speed threshold for the left front window is 10 rad / s, the preset speed threshold for the left rear window is 12 rad / s, the preset speed threshold for the right front window is 12 rad / s, and the preset speed threshold for the right rear window is 13 rad / s.

[0065] The preset speed threshold for each window is set based on the positional relationship between the target door, window, and pressure relief valve. For example, the preset speed threshold for each window is a pre-set baseline value used to determine whether the vehicle's pressure relief valve is in a critical state that could trigger a pressure sensation. The preset speed threshold for each window is closely related to the spatial position between the target door, window, and vehicle pressure relief valve, and is pre-calibrated.

[0066] In this embodiment, if the opening speed of the vehicle's pressure relief valve is greater than a preset speed threshold corresponding to the target window, the target window and / or non-target windows are controlled to open according to a first preset strategy. A target window is a window whose preset speed threshold is less than or equal to the valve opening speed. In other words, if the opening speed of the vehicle's pressure relief valve is greater than the preset speed threshold of a window, then that window is the target window. A non-target window is a window whose preset speed threshold is greater than the valve opening speed. In other words, if the opening speed of the vehicle's pressure relief valve is less than or equal to the preset speed threshold of a window, then that window is a non-target window. Taking the preset speed threshold mentioned above as an example, if the valve opening speed is 11 rad / s, then the left front window is the target window, and the right front window, left rear window, and right rear window are non-target windows. That is, if there is a target window whose preset speed threshold is less than or equal to the valve opening speed, the controller opens the target window and / or non-target window based on the first preset strategy.

[0067] In summary, the controller controls the window opening based on the movement state of the vehicle's pressure relief valve, including at least one of the following: if the valve opening degree of the vehicle's pressure relief valve is greater than a preset opening degree threshold corresponding to the target window, the target window and / or non-target window are controlled to open according to a first preset strategy; if the valve opening speed of the vehicle's pressure relief valve is greater than a preset speed threshold corresponding to the target window, the target window and / or non-target window are controlled to open according to the first preset strategy. This embodiment sets up a dual judgment mechanism based on the valve opening degree and opening speed of the vehicle's pressure relief valve, and combines it with preset thresholds for each window for intelligent control. This can more accurately identify the trend of the pressure pressure sensation, thereby opening the window at the optimal time and achieving the effect of actively suppressing the pressure pressure sensation.

[0068] In other embodiments, a vehicle pressure relief valve is individually installed near each door. Here, "nearby" can be understood as the vehicle body's fixed mounting area adjacent to the door, such as the corresponding body pillar, door frame perimeter, or side panel cavity. For example, in this embodiment, a vehicle pressure relief valve is individually installed near each of the left front door, right front door, left rear door, and right rear door. In this embodiment, in response to detecting that a target door is closing, the controller can acquire the valve plate movement state of multiple vehicle pressure relief valves deployed within the vehicle and control the window opening based on the valve plate movement state of each vehicle pressure relief valve.

[0069] For example, the controller can control the opening of the vehicle windows based on the valve opening degree of the pressure relief valve of each vehicle. For instance, if the valve opening degree of the pressure relief valve of the target vehicle is greater than a preset opening threshold, the target window and / or non-target window are controlled to open according to a first preset strategy. Here, the preset opening threshold is a pre-set valve opening threshold.

[0070] When the target door is closed, the air pressure inside the vehicle increases, causing at least one of the multiple vehicle pressure relief valves deployed within the vehicle to open. In cases where multiple vehicle pressure relief valves are deployed, the target valve is the one whose valve opening degree exceeds a preset threshold, and the target window is the window located on the door where the target valve is located. Non-target windows are windows not located on the door where the target valve is located.

[0071] Taking a preset opening threshold of 45° as an example, if the valve plate opening of the vehicle pressure relief valve installed near the left front door is 46°, the valve plate opening of the vehicle pressure relief valve installed near the right front door is 47°, the valve plate opening of the vehicle pressure relief valve installed near the left rear door is 44°, and the valve plate opening of the vehicle pressure relief valve installed near the right rear door is 44°, the controller determines that the vehicle pressure relief valves installed near the left front door and the vehicle pressure relief valve installed near the right front door are target vehicle pressure relief valves, determines that the windows installed on the left front door and the windows installed on the right front door are target windows, and determines that the windows installed on the left rear door and the windows installed on the right rear door are non-target windows. The controller can control the windows installed on the left front door and the windows installed on the right front door, and / or, the windows installed on the left rear door and the windows installed on the right rear door to open based on a first preset strategy.

[0072] For another example, the controller can control the opening of the vehicle windows based on the valve opening speed of each pressure relief valve. For instance, if the valve opening of the pressure relief valve of the target vehicle is greater than a preset opening speed greater than a preset speed threshold, the target window and / or non-target window are controlled to open according to a first preset strategy. Here, the preset speed threshold is a pre-set threshold for the valve opening speed.

[0073] When the target door is closed, the air pressure inside the vehicle increases, causing at least one of the multiple vehicle pressure relief valves deployed within the vehicle to open. In cases where multiple vehicle pressure relief valves are deployed, the target valve is the one whose valve plate opens at a speed exceeding a preset threshold, and the target window is the window located on the door where the target valve is located. Non-target windows are windows not located on the door where the target valve is located.

[0074] Taking a preset speed threshold of 14 rad / s as an example, if the valve plate opening speed of the vehicle pressure relief valve installed near the left front door is 11 rad / s, the valve plate opening speed of the vehicle pressure relief valve installed near the right front door is 13 rad / s, the valve plate opening speed of the vehicle pressure relief valve installed near the left rear door is 13 rad / s, and the valve plate opening speed of the vehicle pressure relief valve installed near the right rear door is 14 rad / s, the controller determines that the vehicle pressure relief valves installed near the left front door, the right front door, and the left rear door are target vehicle pressure relief valves, determines that the windows installed on the left front door, the right front door, and the left rear door are target windows, and determines that the window installed on the right rear door is a non-target window. The controller can control the windows installed on the left front door, the right front door, and the left rear door, and / or the window installed on the right rear door to open based on a first preset strategy.

[0075] In summary, the controller controls the opening of the vehicle windows based on the movement state of the valve plate of the vehicle's pressure relief valve, including at least one of the following: if the valve plate opening degree of the target vehicle's pressure relief valve is greater than a preset opening degree threshold, the target window and / or non-target window are controlled to open according to a first preset strategy; if the valve plate opening speed of the target vehicle's pressure relief valve is greater than a preset speed threshold, the target window and / or non-target window are controlled to open according to the first preset strategy. This embodiment automatically controls the windows by individually setting a vehicle pressure relief valve near each door and based on the valve plate opening degree and / or opening speed of the vehicle's pressure relief valve. This allows for real-time sensing and response to changes in the vehicle's internal air pressure, enabling rapid adjustment of the window state to balance the air pressure, thereby effectively alleviating the pressure sensation caused by closing the door and improving the user's comfort experience.

[0076] In some embodiments, the first preset strategy control includes at least one of the following: controlling the target window to open; if the number of target windows is greater than 2, controlling the target windows to open simultaneously; if the number of target windows is greater than 2, controlling the target windows to open simultaneously according to the second preset strategy; if the number of target windows is greater than 2, controlling the target windows to open sequentially according to a preset order; and controlling the target window and / or non-target windows to open based on the detection results of objects next to the target window.

[0077] For example, after identifying the target windows, if the number of target windows is greater than or equal to 2, these multiple target windows are controlled to open simultaneously. It should be understood that "simultaneous" in this embodiment can be understood as the difference in opening time being within a preset range, such as [0 seconds, 5 seconds].

[0078] For example, after identifying the target windows, if the number of target windows is greater than or equal to two, the controller opens multiple target windows sequentially according to a preset order. For instance, the preset order could be from front to back, or from left to right. Alternatively, the preset order could include at least one of the following: a preset opening threshold from largest to smallest; a preset speed threshold from largest to smallest; or a distance from the target door from closest to farthest. In other words, if there are multiple target windows, the controller can open them according to the preset opening thresholds corresponding to the target windows in a descending order. Alternatively, if there are multiple target windows, the controller can open them according to the preset speed thresholds corresponding to the target windows in a descending order. Or, if there are multiple target windows, the controller can open them based on the distance between the target windows and the target door in a descending order. In practice, these three preset orders are not isolated; they can be used in combination. For example, a more intelligent and flexible control logic can be formed by comprehensively considering preset opening thresholds, preset speed thresholds, and door positions. This enables the vehicle to achieve optimal relief of ear pressure in various door closing scenarios. This application embodiment, by setting multiple preset sequences and combining them with door closing state parameters for comprehensive judgment, can more accurately control the window opening sequence, thereby effectively alleviating the ear pressure sensation for occupants.

[0079] For example, after identifying the target windows, if the number of target windows is greater than or equal to two, the second control strategy controls these target windows to open simultaneously. The second control strategy involves controlling target windows that meet a first condition to open by a first descent distance, and controlling target windows that do not meet the first condition to open by a second descent distance, where the second descent distance is less than the first descent distance. The first condition includes: the target window is installed on a target door and / or a target object exists next to the target window. In other words, if the number of target windows is greater than or equal to two, the second control strategy controls these target windows to open simultaneously. The second control strategy is: the descent distance of a window installed on a target door is greater than the descent distance of a window not installed on a target door, and / or, the descent distance of a target window next to a target object is greater than the descent distance of a target window not next to a target object. The target object can be a driver or passenger.

[0080] In this embodiment, the controller can acquire the distribution of target objects within the vehicle cabin through various means. For example, it can acquire the distribution of target objects within the vehicle cabin based on detection signals from seat pressure sensors installed in the cabin, scanning data from in-vehicle millimeter-wave radar, and the switching signals of seat belt buckles, as well as by combining image recognition results from in-vehicle cameras.

[0081] For another example, after the target window is identified, the target window and / or non-target windows are controlled to open based on the detection results of objects next to the target window.

[0082] For example, if no target object is detected next to the target window, the controller will open the target window. This is because opening a window in a passenger area would cause the air pressure surge when the door closes, directly blowing air towards the occupants and causing discomfort. Therefore, opening windows in unoccupied areas allows for pressure relief while maintaining passenger comfort.

[0083] For example, if a first-type target object is detected next to the target window, at least one non-target window will be opened. The first-type target object includes special targets such as the elderly or children. To avoid discomfort caused by opening the window, the controller will open at least one non-target window when a first-type target object is present next to the target window.

[0084] For example, if a second type of target object is detected next to the target vehicle window, the target vehicle window can be opened. This second type of target object includes targets other than special groups such as the elderly or children; for example, it could be an adult. In the presence of a second type of target object next to the target vehicle window, the window can be opened to quickly reduce the pressure difference and avoid ear pressure.

[0085] For example, if no target object is detected near any of the car windows, all windows will be opened. The controller will open all windows even when no target object is detected near any of the car windows.

[0086] For example, if a target object is detected next to all windows, the sunroof will be opened. The controller will open the sunroof if a target object is detected next to all windows.

[0087] In this embodiment, the controller uses the detection results of the target object next to the target window to reasonably control the opening of the target window or non-target window, so as to achieve depressurization in the cabin while taking into account the riding comfort of the driver and passengers.

[0088] The following describes a method for controlling a vehicle window provided in an embodiment of this application, using a specific application scenario as an example.

[0089] The sensation of pressure on the ears when a car door is closed refers to the sudden increase in air pressure inside the car when the car is stationary and the windows are closed. This pressure cannot escape quickly, causing a large fluctuation in air pressure at the ears and impacting the eardrums, resulting in a feeling of pressure and discomfort for the people inside the car.

[0090] Typically, for framed, mechanically closed car doors, the solution to the door closing pressure issue is to increase the flow area of ​​the vehicle's pressure relief valve and the effective opening area of ​​the internal and external circulation holes. However, considering the cabin static pressure requirements and the need for mold standardization, simply increasing the flow area of ​​the vehicle's pressure relief valve and the effective opening area of ​​the internal and external circulation holes will not solve the door closing pressure issue.

[0091] Meanwhile, frameless doors and power doors can also effectively avoid the ear-pressure feeling when closing doors. Specifically, when the door is opened, the door glass lowers; when the door is closed, the door glass rises again. The frameless door structure's control logic for the door glass to rise after closing effectively solves the ear-pressure feeling when closing doors. Another advantage is power doors. When power doors close, the door lock automatically engages, requiring no external closing force. The air pressure fluctuation at the ear level inside the car is minimal, virtually eliminating the ear-pressure feeling when closing doors.

[0092] This application targets vehicle models with window frames and mechanically closing doors. When closing the doors within the designed closing force range, there is generally no pressure sensation in the ears inside the vehicle. However, the closing force is determined by the user and cannot be controlled. When the closing force exceeds the upper limit of the designed closing force, varying degrees of pressure sensation will occur in the ears of the person inside the vehicle. Generally, the greater the closing force, the greater the pressure difference between the inside and outside of the vehicle, the larger the opening angle of the vehicle's pressure relief valve, and the stronger the instantaneous pressure sensation in the ears. Therefore, this application proposes a method to monitor the movement state of the vehicle's pressure relief valve and establish the relationship between the movement state of the valve and the door closing pressure noise, thereby lowering the door glass to solve the problem of door closing pressure sensation in the vehicle when the actual closing force is large.

[0093] The following section introduces the method for determining the preset threshold corresponding to each window. It should be understood that the following explanation uses the preset opening threshold as an example to illustrate the method for determining the preset opening threshold. The method for determining the preset speed threshold is similar to the method for determining the preset opening threshold, and will not be elaborated upon.

[0094] This application proposes for the first time a method for determining the door-closing ear-pressure noise threshold, and clarifies the mapping relationship between the door opening threshold and the door-closing ear-pressure noise threshold. Taking the determination of the preset opening threshold corresponding to the windshield as an example, such as... Figure 2 As shown, when the front door (e.g., the left or right front door) is closed with the minimum designed closing force, the valve opening angle of the vehicle's pressure relief valve is ψ0, and the noise level at the passenger's ear when the front door is closed is S0. If the closing force of the front door is less than the minimum designed closing force, the front door cannot close properly due to insufficient force. If the closing force of the front door is greater than the minimum designed closing force, both doors can close normally. As the closing force of the front door gradually increases, the opening angle of the vehicle's pressure relief valve also increases. When the opening angle of the vehicle's pressure relief valve is ψ, and the noise level at the passenger's ear is S, the noise level is at the critical point of ear pressure. The opening angle of the vehicle's pressure relief valve at this point is defined as the preset opening threshold corresponding to the front window.

[0095] The following is a method for determining the preset opening threshold for each vehicle window. For example, in vehicles with window frames and mechanically closed doors, when any door is closed with a force slightly greater than normal, the occupants experience a noticeable, unacceptable pressure on their ears. The left front door is closed using the minimum design closing force. As the closing force gradually increases, the opening angle of the vehicle's pressure relief valve is recorded, along with the noise level at the occupants' ears at different closing forces. The same method is used to test the opening angle of the vehicle's pressure relief valve and the noise level at the occupants' ears for the left rear door, right front door, and right rear door at different closing forces. The test data is played back in the sound quality evaluation room, and an evaluation team is invited to assess and determine the door-closing pressure noise threshold. For example, the door-closing pressure noise threshold for the left front door is determined to be 53 dB(A), corresponding to a pressure relief valve opening angle of 40°, which is the preset opening threshold for the left front window. The noise threshold for the left rear door's closing pressure sensation is determined to be 55 dB(A), corresponding to a valve opening angle of 45° for the vehicle's pressure relief valve, which is the preset opening threshold for the left rear window. The noise threshold for the right front door's closing pressure sensation is determined to be 53 dB(A), corresponding to a valve opening angle of 45° for the vehicle's pressure relief valve, which is the preset opening threshold for the right front window. The noise threshold for the right rear door's closing pressure sensation is determined to be 54 dB(A), corresponding to a valve opening angle of 44° for the vehicle's pressure relief valve, which is the preset opening threshold for the right rear window.

[0096] In this embodiment of the application, the control of the vehicle window can be achieved through a control system, such as... Figure 3 As shown. The control system 300 includes a controller 410, a data acquisition device 320, window lifting devices 3301, 3302, 3303, and 3304, and a vehicle pressure relief valve 340.

[0097] The controller 310 can communicate with the data acquisition device 320, and the controller 310 can also communicate with the window lift devices 3301-3304. The data acquisition device 320 is used to acquire the valve opening degree of the vehicle's pressure relief valve.

[0098] The controller 310 is used to acquire the current valve opening degree of the vehicle pressure relief valve 340 at the current moment during the closing process of the target door of the vehicle. For example, the controller 310 communicates with the acquisition device 320 to acquire the current valve opening degree of the vehicle pressure relief valve 340 at the current moment. The window lift device 3301 corresponds to the left front door and is used to control the lifting of the window on the left front door. The window lift device 3302 corresponds to the left rear door and is used to control the lifting of the window on the left rear door. The window lift device 3303 corresponds to the right front door and is used to control the lifting of the window on the right front door. The window lift device 3304 corresponds to the right front door and is used to control the lifting of the window on the right front door. Specifically, in response to detecting that the target door is closing, the controller 310 acquires the movement state of the valve plate of the vehicle pressure relief valve 440 through the acquisition unit 310. The controller 310 identifies the target window based on the method described above and issues a command to the corresponding window lift device to lower the window on the door, ensuring that the sound pressure level at the ear of the person inside the vehicle is below the ear pressure threshold S, thus ensuring that the door is closed normally without any door ear pressure. If the acquisition unit 320 detects that the valve plate angle of the vehicle pressure relief valve is below ψ0 when the door is closed, the window lift device will not operate and the control process will not be triggered. After the valve plate of the vehicle pressure relief valve 340 is reset, the controller 310 can also control the target window to automatically rise.

[0099] For example, during the closing of the target vehicle door, the acquisition unit 320 detects that the valve plate opening angle of the vehicle pressure relief valve 340 is greater than 40°. The acquisition unit 320 transmits the signal to the controller 310, which in turn issues commands to the window lifters 3301 and 3303 to lower the windows on the left and right front doors. After the windows are lowered, the peak sound pressure level at the ear of the person inside the vehicle decreases to 52.4 dB(A). When the acquisition unit 320 detects that the valve plate opening angle of the vehicle pressure relief valve is greater than 45°, the acquisition unit 320 transmits the signal to the controller 310, which in turn issues commands to the window lifters 3304 and 3302 to lower the windows on the right and left rear doors, further reducing the peak sound pressure level at the ear of the person inside the vehicle to 54.3 dB(A).

[0100] The vehicle pressure relief valve 340 can be a single vehicle pressure relief valve located inside the vehicle. Alternatively, the vehicle pressure relief valve 340 can be a vehicle pressure relief valve located near each door.

[0101] Figure 4 This diagram illustrates the effect of actively controlling the forward and backward movement of the window on the left front door. Figure 4 As shown, the solid line represents the cabin noise level over time when the windows are closed; the solid line also represents the cabin noise level over time when the windows are open. It can be seen that the cabin noise level is significantly lower when the windows are open than when they are closed.

[0102] Figure 5 This diagram illustrates the effect of actively controlling the front and rear of the window on the right rear door. (For example...) Figure 5 As shown, the solid line represents the cabin noise level over time when the windows are closed; the solid line also represents the cabin noise level over time when the windows are open. It can be seen that the cabin noise level is significantly lower when the windows are open than when they are closed.

[0103] The following section uses the example of a controller controlling the opening of a vehicle window based on the valve opening degree of the vehicle's pressure relief valve to introduce a window control method provided in this application. Figure 6 As shown, the method includes: S601, the controller detects whether the target door is closing.

[0104] The controller can detect whether the target door is closing in a variety of ways, as described above, and will not be repeated here.

[0105] S602, the controller controls the acquisition unit to acquire the opening and closing angle of the valve plate of the vehicle's pressure relief valve.

[0106] S603, the controller obtains the valve plate opening angle of the vehicle's pressure relief valve from the acquisition unit.

[0107] The controller obtains the valve opening angle of the vehicle's pressure relief valve from the acquisition unit and executes different control processes based on the valve opening angle. For example, if the opening angle of the vehicle's pressure relief valve is less than the valve opening angle ψ0 corresponding to the minimum design closing force of the target door, the controller continues to execute S601. If the opening angle of the vehicle's pressure relief valve is greater than the preset opening threshold corresponding to any window, the controller executes S604.

[0108] S604, when the opening angle of the vehicle pressure relief valve is greater than the preset opening threshold corresponding to any window, the controller controls the target window and / or non-target window to open according to the first preset strategy.

[0109] For example, the controller sends a command to the window regulator corresponding to the target window, and / or sends a command to the window regulator corresponding to a non-target window. The window regulator corresponding to the target window controls the target window to open, and / or the window regulator corresponding to the non-target window controls the non-target window to open.

[0110] After the window is opened, the controller continues to acquire the opening and closing angle of the vehicle's pressure relief valve. If the opening and closing angle of the vehicle's pressure relief valve is less than or equal to all preset opening thresholds and greater than the valve plate opening and closing angle corresponding to the minimum design closing force of the target door, the controller determines that the door is closed in place and the controller can execute S605.

[0111] S605, the controller confirms the door closing is complete.

[0112] Furthermore, when the opening angle of the vehicle's pressure relief valve is less than or equal to the second opening threshold, the controller controls the target window to close via the lifting device corresponding to the target window. The method described in this application enables the simultaneous closing of more than one door, where each door can be closed by an independent door glass lowering control system. This ultimately achieves normal door closing force between the valve opening angle ψ0 of the vehicle's pressure relief valve corresponding to the minimum designed closing force and the valve opening angle ψ of the vehicle's pressure relief valve corresponding to the door closing pressure noise threshold, ensuring normal door closing without any door pressure sensation at the ears of passengers inside the vehicle.

[0113] This application enables the simultaneous closing of more than one target vehicle door, with each of these doors controlled by an independent window lift device. Ultimately, it achieves normal door closing force between the valve opening angle ψ0 of the vehicle pressure relief valve corresponding to the minimum designed closing force and the valve opening angle ψ of the vehicle pressure relief valve corresponding to the door closing pressure noise threshold, ensuring normal door closing without any door pressure sensation at the ear of the person inside the vehicle.

[0114] This application also provides a vehicle window control device, such as... Figure 7 As shown, the control device 700 may include a control unit 710. The control device 700 may, for example, be the controller described above.

[0115] The control unit 710 is used to control the opening of the window in response to the detection that the target door is closing, based on the movement state of the valve plate of the vehicle pressure relief valve.

[0116] The control unit 710 is also configured to: if the valve opening degree of the vehicle pressure relief valve is greater than the preset opening degree threshold corresponding to the target window, control the target window and / or non-target window to open according to the first preset strategy, wherein each window corresponds to a separate preset opening degree threshold, and the preset opening degree threshold is set according to the positional relationship of the target door, window, and pressure relief valve; if the valve opening speed of the vehicle pressure relief valve is greater than the preset speed threshold corresponding to the target window, control the target window and / or non-target window to open according to the first preset strategy, wherein each window corresponds to a separate preset speed threshold, and the preset speed threshold is set according to the positional relationship of the target door, window, and pressure relief valve.

[0117] The control unit 710 is also configured to control the opening of the target window and / or non-target window according to a first preset strategy if the valve plate opening degree of the target vehicle's pressure relief valve is greater than a preset opening degree threshold, wherein a target window is provided on the door where the target vehicle's pressure relief valve is located; and to control the opening of the target window and / or non-target window according to a first preset strategy if the valve plate opening speed of the target vehicle's pressure relief valve is greater than a preset speed threshold, wherein a target window is provided on the door where the target vehicle's pressure relief valve is located.

[0118] The control unit 710 is also configured to perform at least one of the following: if no target object is detected next to the target window, control the target window to open; if a first type of target object is detected next to the target window, control at least one non-target window to open; if a second type of target object is detected next to the target window, control the target window to open; if no target object is detected next to any of the windows, control all windows to open; if a target object is detected next to all the windows, control the sunroof to open. The control unit 710 is also configured to perform at least one of the following: controlling the opening speed of the window based on the closing force of the target door, wherein the opening speed and closing force are positively correlated; controlling the opening speed of the window based on the closing acceleration of the target door, wherein the opening speed and closing acceleration are positively correlated; controlling the opening speed of the window based on the closing speed of the target door, wherein the opening speed and closing speed are positively correlated; controlling the opening distance of the window based on the closing force of the target door, wherein the opening distance and closing force are positively correlated; controlling the opening distance of the window based on the closing acceleration of the target door, wherein the opening distance and closing acceleration are positively correlated; and controlling the opening distance of the window based on the closing speed of the target door, wherein the opening distance and closing speed are positively correlated.
