[0059] Further, the vehicle further includes a speed sensor 3 provided on the vehicle door, and the speed sensor 3 is used to detect the movement speed of the vehicle door. The speed sensor 3 is connected to the control device 2. In this embodiment, the speed sensor 3 is used to detect the angular velocity of the vehicle door. In other embodiments, the speed sensor 3 can also be used to detect the linear velocity of the vehicle door.

[0060] Furthermore, the vehicle further comprises a vehicle speed sensor 4 , which is used to detect the vehicle speed. The vehicle speed sensor 4 is connected to the control device 2 .

[0061] Furthermore, the control device 2 may also be connected to the power system 5 of the vehicle to determine whether the vehicle is in an ignition-off state according to operating parameters of the power system 5 .

[0062] Furthermore, the control device 2 may also be connected to the door lock assembly 6 of the vehicle door or a controller connected to the door lock assembly to determine whether the door lock is in an unlocked state.

[0063] Furthermore, an air pressure sensor 7 may be provided in the sealing strip, and the air pressure sensor 7 is used to detect the air pressure in the sealing strip. The control device 2 may be used to obtain data detected by the air pressure sensor 7 .

[0064] The control device 2 includes: a processor 1001 (e.g., a CPU), a memory 1002, a timer 1003, etc. The components in the control device 2 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory.

[0065] Those skilled in the art will understand that Figure 1 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0066] like Figure 1 As shown, the memory 1002 as a storage medium may include an air pressure adjustment program for the door seal strip. Figure 1 In the device shown, the processor 1001 can be used to call the air pressure adjustment program of the vehicle door sealing strip stored in the memory 1002, and execute the relevant steps of the air pressure adjustment method of the vehicle door sealing strip in the following embodiments.

[0067] An embodiment of the present invention further provides a method for regulating the air pressure of a vehicle door sealing strip, which is applied to the above-mentioned vehicle.

[0068] Reference Figure 2 , an embodiment of the air pressure regulating method of the vehicle door sealing strip of the present application is proposed. In this embodiment, the air pressure regulating method of the vehicle door sealing strip comprises:

[0069] Step S10, obtaining the action characteristic parameters of the door where the sealing strip is located and the current air pressure in the sealing strip;

[0070] The action characteristic parameters specifically include characteristic parameters of the action states of the door opening action and / or door closing action of the vehicle door. The action characteristic parameters include executing the door opening action, completing the door opening action, executing the door closing action and / or completing the door opening action.

[0071] The action characteristic parameters can be specifically determined by obtaining the state detection parameters of the door and / or the operation parameters of the vehicle and the like.

[0072] The current air pressure in the sealing strip can be obtained by acquiring data currently detected by an air pressure sensor arranged in the sealing strip.

[0073] Step S20, determining a target air pressure range of the sealing strip according to the action characteristic parameters;

[0074] The target air pressure range is specifically the target range of the air pressure value in the sealing strip that needs to be reached to meet the requirements of door sealing, noise in the vehicle cabin, noise generated during the operation of the door and / or the door reaching a preset life.

[0075] The target air pressure range may be a numerical interval having a maximum value and a minimum value, or a numerical interval having a maximum value but not having a minimum value, or a numerical interval having a minimum value but not having a maximum value.

[0076] Different action characteristic parameters correspond to different target air pressure ranges. The corresponding relationship between the action characteristic parameters and the target air pressure range can be preset, and the corresponding relationship may include a mapping relationship, a calculation relationship, etc. Based on the corresponding relationship, the target air pressure range corresponding to the current action characteristic parameter can be determined. Specifically, when the corresponding relationship is a mapping relationship, different action characteristic parameters are mapped to different preset air pressure ranges, and based on the mapping relationship, the preset air pressure range corresponding to the current action characteristic parameter can be determined as the target air pressure range. When the corresponding relationship is a calculation relationship, the action characteristic parameter can be characterized by a characterization value, and different action characteristic parameters correspond to different characterization values. The quantitative relationship between the characterization value and the critical value (maximum value and / or minimum value) of the target air pressure range can be established in advance. Based on this, the characterization value corresponding to the current action characteristic parameter is determined, and the critical value of the target air pressure range can be calculated by substituting the current characterization value into the quantitative relationship. Based on the critical value, the corresponding air pressure range is determined as the target air pressure range.

[0077] Step S30, determining the air pressure adjustment parameter of the sealing strip according to the target air pressure range and the current air pressure;

[0078] The air pressure adjustment parameters may include the air pressure adjustment direction (such as increasing the air pressure or decreasing the air pressure). In addition to the air pressure adjustment direction, the air pressure adjustment parameters may also include the air pressure adjustment rate and / or the air pressure adjustment amplitude.

[0079] Specifically, the magnitude relationship and / or quantity relationship between the target air pressure range and the current air pressure is determined, and the air pressure adjustment parameter is determined based on the magnitude relationship and / or quantity relationship.

[0080] Step S40: controlling the air pressure regulator of the sealing strip to operate according to the air pressure adjustment parameter.

[0081] Specifically, the air pressure adjustment parameters include controlling the air pressure regulator to inflate air into the sealing strip when the air pressure is increased; and the air pressure adjustment parameters include controlling the air pressure regulator to extract air from the inside of the sealing strip when the air pressure is reduced.

[0082] A method for regulating the air pressure of a vehicle door sealing strip is proposed in an embodiment of the present invention. The method determines corresponding air pressure regulation parameters based on the action characteristic parameters of the vehicle door where the sealing strip is located and the current air pressure of the sealing strip to control the operation of the air pressure regulator of the sealing strip. Based on this, the air pressure in the sealing strip of the vehicle door is no longer fixed, but can be adjusted to suit the air pressure required by the actual action of the vehicle door, thereby ensuring that the air pressure of the sealing strip during actual use of the vehicle can reach the air pressure required by the actual application scenario, which can effectively improve the performance of the sealing strip during the use of the vehicle door and improve the user experience during the use of the vehicle.

[0083] Further, in this embodiment, when the current air pressure is outside the target air pressure range and the current air pressure is greater than the maximum air pressure value of the target air pressure range, determining the air pressure adjustment parameter includes reducing the air pressure; or, when the current air pressure is outside the target air pressure range and the current air pressure is less than the minimum air pressure value of the target air pressure range, determining the air pressure adjustment parameter includes increasing the air pressure.

[0084] When the target air pressure range is a numerical interval with a maximum air pressure value and a minimum air pressure value, when the current air pressure is greater than the maximum air pressure value of the target air pressure range, the air pressure adjustment parameters include reducing the air pressure; when the current air pressure is less than the minimum air pressure value of the target air pressure range, the air pressure adjustment parameters include increasing the air pressure; when the current air pressure is greater than or equal to the minimum air pressure value and less than or equal to the maximum air pressure value, the current air pressure of the sealing strip is maintained unchanged.

[0085] When the target air pressure range is a numerical interval less than or equal to the maximum air pressure value, when the current air pressure is greater than the maximum air pressure value, the air pressure adjustment parameters include reducing the air pressure, and when the current air pressure is less than or equal to the maximum air pressure value, maintaining the current air pressure of the sealing strip unchanged.

[0086] When the target air pressure range is a numerical interval greater than or equal to the minimum air pressure value, when the current air pressure is less than the minimum air pressure value, the air pressure adjustment parameters include increasing the air pressure, and when the current air pressure is greater than or equal to the minimum air pressure value, maintaining the current air pressure of the sealing strip unchanged.

[0087] Based on this, when the current air pressure exceeds the target air pressure range, the air pressure adjustment direction is determined by the size relationship between the current air pressure and the critical value of the target air pressure range, which is conducive to the current air pressure approaching the target air pressure range required for the current door action.

[0088] Furthermore, in order to improve the accuracy of air pressure regulation of the sealing strip and ensure that the air pressure in the sealing strip can quickly and accurately reach the target air pressure range, when the current air pressure is greater than the maximum air pressure value, the first deviation between the current air pressure and the maximum air pressure value can also be determined, and the air pressure adjustment amplitude or the air pressure adjustment speed is determined according to the first deviation, and the air pressure adjustment parameters include reducing the air pressure and the air pressure adjustment amplitude or the air pressure adjustment speed here; when the current air pressure is less than the minimum air pressure value, the second deviation between the current air pressure and the minimum air pressure value can also be determined, and the air pressure adjustment amplitude or the air pressure adjustment speed is determined according to the second deviation, and the air pressure adjustment parameters include increasing the air pressure and the air pressure adjustment amplitude or the air pressure adjustment speed here.

[0089] Further, based on the above embodiment, another embodiment of the air pressure adjustment method of the vehicle door sealing strip of the present application is proposed. Figure 3 The step of determining the target air pressure range of the sealing strip according to the action characteristic parameters comprises:

[0090] Step S21, when the action characteristic parameter is a door closing action, obtaining the movement speed of the door;

[0091] Here, executing the door closing action specifically refers to the vehicle door moving from an open state toward a closed position under the drive of an external force (such as manual drive by a user, etc.).

[0092] In this embodiment, the movement speed is the angular velocity of the door, which can be obtained by obtaining the data currently detected by the angular velocity sensor on the door. In other embodiments, the movement speed may also refer to the linear velocity of the door.

[0093] Step S22, determining the target air pressure range according to the movement speed.

[0094] Specifically, when the movement speed reaches a preset condition, the preset air pressure range can be determined as the target air pressure range. For example, when the movement speed is within a preset interval, the preset air pressure range can be determined as the target air pressure range.

[0095] Alternatively, a correspondence between movement speed and target air pressure range can be established in advance, and different movement speeds correspond to different target air pressure ranges. Specifically, the greater the movement speed, the more positively correlated it is with the critical value or mean value of the target air pressure range. Based on this correspondence, the target air pressure range corresponding to the current movement speed can be determined.

[0096] In this embodiment, the magnitude of the movement speed can reflect the magnitude of the contact force when the vehicle door contacts the vehicle body, thereby achieving the characterization of the noise related to the door closing action, the impact on the life of the structural parts related to the action, the firmness of the door closing, etc., and the target air pressure range of the sealing strip is determined according to the movement speed of the door. Based on this, it can be ensured that the air pressure of the sealing strip can adapt to the door closing action, and that the air pressure of the sealing strip can meet the requirements of noise, life, door closing safety, etc., so as to effectively improve the performance of the sealing strip during the door closing process and further improve the user's experience of closing the door.

[0097] Further, in this embodiment, after the step of obtaining the movement speed of the door, the method further includes: when the movement speed is greater than or equal to a first preset speed, determining the preset air pressure upper limit value adjusted to the sealing strip as the air pressure adjustment parameter; when the movement speed is less than the first preset speed and greater than a second preset speed, executing the step of determining the target air pressure range according to the movement speed, and the air pressure within the target air pressure range is less than the preset air pressure upper limit value; when the movement speed is less than or equal to the second preset speed, outputting a first prompt message, the first prompt message being used to prompt that the door cannot be closed;

[0098] Wherein, the second preset speed is smaller than the first preset speed.

[0099] The first preset threshold is specifically a critical value of the door movement speed for distinguishing whether the contact force between the door and the vehicle body is too large when the door reaches the closed position.

[0100] The second preset threshold is specifically a door movement speed critical value for distinguishing whether the door can be moved to the closed position and locked.

[0101] The preset upper limit of air pressure is specifically the maximum value that the air pressure in the sealing strip that the air pressure regulator allows to adjust is allowed to reach.

[0102] The first prompt information may include display, sound and / or light. Specifically, the vehicle prompt device or the terminal device connected to the vehicle and equipped with the preset application may be controlled to output the first prompt information.

[0103] When the movement speed is greater than or equal to the first preset speed, it indicates that the closing force of the door is too large. At this time, the air pressure in the sealing strip is directly adjusted to the preset upper limit of the air pressure through the air pressure regulator, so as to ensure that the sealing strip has sufficient air pressure to buffer the closing force and avoid damage to related components due to excessive noise or impact when closing the door.

[0104] When the movement speed is less than or equal to the second preset speed, it indicates that the closing force of the door is too small, which may cause the door to fail to reach the closed position or fail to lock after reaching the closed position. At this time, the output of the first prompt information can ensure that the user can know the state of the door not being closed in time, which is conducive to improving the safety of vehicle use.

[0105] When the movement speed is between the first preset speed and the second preset speed, it indicates that the closing force of the door is moderate. At this time, the target air pressure range is determined according to the actual movement speed of the door, thereby ensuring that the air pressure in the sealing strip accurately matches the current closing force of the door, neither too large nor too small, thereby further improving the performance of the sealing strip and ensuring that the door is safely closed without excessive noise and / or impact force, thereby further improving the user's closing experience.

[0106] Further, in this embodiment, referring to Figure 4 , before step S22, further comprising:

[0107] Step S01, obtaining a target closing force range and / or a target door closing noise range of the vehicle door, wherein a lower limit value of the target closing force range is a minimum closing force value allowed for closing and locking the vehicle door, and an upper limit value of the target closing force range is a maximum closing force value allowed for the vehicle door and / or a vehicle body matched with the vehicle door to reach a target lifespan;

[0108] The closing force specifically refers to the external driving force for the door to perform the closing action (such as the user's hand push force, etc.). The target closing force range can be a pre-calibrated fixed range, or a numerical range obtained according to the actual state of the door or the type of vehicle.

[0109] The closing force within the target closing force range can achieve the closing and locking of the door and meet the requirement that the door and / or the vehicle body matched with the door reach the target life.

[0110] The target door closing noise range specifically refers to the allowable numerical range (such as decibel value range or rating value range, etc.) of the noise generated when the door reaches the closed position when executing the door closing action. The target door closing noise range can be a pre-calibrated fixed range, or a range determined according to a user setting instruction.

[0111] Step S02, establishing a target corresponding relationship between the movement speed and the target air pressure range according to the target closing force range and / or the target door closing noise range;

[0112] In this embodiment, a target corresponding relationship is established according to a target closing force range and a target door closing noise range. Specifically, the first preset corresponding relationship and the second preset corresponding relationship corresponding to the preset air pressure values ​​of the plurality of sealing strips can be obtained, the first preset corresponding relationship being the corresponding relationship between the door closing force and the movement speed, and the second preset corresponding relationship being the corresponding relationship between the noise value and the movement speed. Based on the plurality of first preset corresponding relationships, a first air pressure value set corresponding to different movement speeds is determined, the first air pressure value set includes a plurality of preset air pressure values, and the door closing force corresponding to the movement speed corresponding to each preset air pressure value in the first air pressure value set is within the target closing force range. Based on the plurality of second preset corresponding relationships, a second air pressure value set corresponding to different movement speeds is determined, the second air pressure value set includes a plurality of preset air pressure values, and the characterization value of the door closing noise corresponding to the movement speed corresponding to each preset air pressure value in the second air pressure value set is within the target door closing noise range. The intersection of the first air pressure value set corresponding to each movement speed and the second air pressure value set corresponding to each movement speed is determined as the target air pressure range corresponding to each movement speed, and the target corresponding relationship is obtained.

[0113] In other embodiments, the target correspondence may also be determined according to one of a target closing force range and a target door closing noise range.

[0114] Based on step S01 and step S02, step S22 includes:

[0115] Step S221, determining the target air pressure range corresponding to the movement speed based on the target corresponding relationship.

[0116] In this embodiment, a target correspondence between the movement speed and the target air pressure range is established based on the target closing force range and / or the target door closing noise range, and the target air pressure range corresponding to the current movement speed is determined based on the target correspondence, thereby ensuring that when the air pressure regulator is operated and regulated according to the target air pressure range and the current air pressure of the sealing strip, the air pressure in the sealing strip can accurately meet the requirements of locking, life and noise level when the car door is closed, so as to further improve the performance of the sealing strip and further improve the user's door closing experience.

[0117] It should be noted that the execution order of step S01 and step S02 and step S10 and step S21 is not specifically limited.

[0118] Further, based on any of the above embodiments, another embodiment of the air pressure adjustment method of the vehicle door sealing strip of the present application is proposed. Figure 5 , the step S20 comprises:

[0119] Step S23, when the action characteristic parameter is to complete the door closing action, determine the first air pressure range as the target air pressure range; the first air pressure range is an air pressure range greater than or equal to a first preset air pressure threshold, and the first preset air pressure threshold is negatively correlated with the maximum noise value allowed in the cabin corresponding to the door.

[0120] Specifically, the greater the maximum noise value is, the smaller the first preset air pressure threshold is; conversely, the smaller the maximum noise value is, the greater the first preset air pressure threshold is.

[0121] The maximum noise value may be a preset fixed value, or a value determined according to a setting instruction input by a user.

[0122] In this embodiment, through the above-mentioned method, it can be ensured that after the door closing action is completed, the sealing strip can provide a sufficiently large air pressure to ensure the sealing state of the vehicle cabin, reduce the noise outside the vehicle from being transmitted into the cabin through the door gap, and ensure that the noise in the cabin can be limited to no more than the maximum noise value under the sealing action of the sealing strip, so as to further improve the performance of the sealing strip and further improve the user experience after the door is closed.

[0123] Furthermore, in this embodiment, step S23 includes: when the action characteristic parameter is to complete the door closing action, if the current air pressure is less than the preset lower air pressure limit of the sealing strip, a second prompt message is output, and the step of determining the first air pressure range as the target air pressure range is executed; wherein, the second prompt message is used to prompt that the sealing strip is at risk of failure.

[0124] The preset lower limit of air pressure is the minimum air pressure value allowed to be reached by the sealing strip under the regulation of the air pressure regulator. The preset lower limit of air pressure is the critical value of air pressure used to identify whether the sealing strip has a risk of failure. When the current air pressure is less than the preset lower limit of air pressure, it indicates that the sealing strip has a risk of failure; otherwise, the sealing strip has no risk of failure.

[0125] The second prompt information can be output in the form of display, sound and / or light, etc. Specifically, the second prompt information can be output through the vehicle-mounted device or a terminal device connected to the vehicle and installed with a preset application.

[0126] In this embodiment, after completing the door closing action, when the current air pressure is too low, in addition to adapting to the maximum noise value to determine the target air pressure range and adjusting the air pressure in the sealing strip, a second prompt message is also output. Based on this, it is ensured that the user can know the failure risk of the sealing strip in time and take timely measures to maintain the sealing strip, thereby further improving the performance of the sealing strip and improving the user experience during vehicle use.

[0127] Further, based on any of the above embodiments, another embodiment of the air pressure adjustment method of the vehicle door sealing strip of the present application is proposed. Figure 6, step S20 comprises:

[0128] Step S24, when the action characteristic parameter is to execute the door opening action, determine the second air pressure range as the target air pressure range; the second air pressure range is an air pressure range less than or equal to a second preset air pressure threshold, and the second preset air pressure threshold is negatively correlated with the maximum sound value allowed to be generated by the door opening action.

[0129] Specifically, the greater the maximum sound value is, the smaller the second preset air pressure threshold is; conversely, the smaller the maximum noise value is, the greater the second preset air pressure threshold is.

[0130] The maximum sound value may be a preset fixed value, or a value determined according to a setting instruction input by a user.

[0131] In this embodiment, the sealing strip generates a reaction force that hinders the opening of the door during the door opening process. The greater the reaction force, the greater the sound generated during the door opening process. Based on this, when the door opening action is performed, the air pressure of the sealing strip is limited through the second air pressure range to avoid the reaction force generated by the sealing strip causing the sound during the door opening process to exceed the maximum allowable sound value, which is beneficial to reducing the noise when the door is opened and further improving the user experience of the door opening process.

[0132] It should be noted that, in the embodiment of the present invention, step S20 includes the above-mentioned step S21, step S22 to step S23, and step S24. In other embodiments, step S20 may also include steps corresponding to one or two of the three methods of determining the target air pressure range defined by step S21, step S22 to step S23, and step S24.

[0133] Further, based on any of the above embodiments, another embodiment of the air pressure regulating method of the vehicle door sealing strip of the present application is proposed. Figure 7 , the action characteristic parameters of the door where the sealing strip is located are obtained including:

[0134] Step S11, obtaining the state information related to the opening and closing of the door and the driving state information of the vehicle where the door is located;

[0135] The state information related to opening and closing includes whether the vehicle door is in a closed state and / or whether the door lock is in an unlocked state. Whether the vehicle door is in a closed state can be detected by a sensor arranged on the vehicle door. Whether the door lock is in an unlocked state can be obtained by obtaining the operation data of the door lock system.

[0136] The driving state information includes the speed range and / or whether the vehicle is turned off. The speed is detected by a speed sensor. Whether the vehicle is turned off is obtained by obtaining the operating data of the vehicle's power system.

[0137] Step S12, when the state information includes that the vehicle door is in an open state and the driving state information includes that the vehicle speed is less than a first preset vehicle speed, determining that the action characteristic parameter is to perform a door closing action;

[0138] Step S13, when the state information includes that the vehicle door is in a closed state and the driving state information includes that the vehicle is not turned off, determining that the action characteristic parameter is to complete the door closing action;

[0139] Step S14, when the state information includes that the door lock of the vehicle door is in an unlocked state and the driving state information includes that the vehicle speed is less than a second preset vehicle speed, determining that the action characteristic parameter is to perform a door opening action.

[0140] In this embodiment, the first preset vehicle speed is equal to the second preset vehicle speed. In other embodiments, the first preset vehicle speed may also be less than or greater than the second preset vehicle speed.

[0141] In this embodiment, by combining the state information related to the opening and closing of the door and the driving state information of the vehicle, it is possible to accurately identify the action characteristic parameters such as executing the door closing action, executing the door opening action and completing the door closing action.

[0142] In other embodiments, the motion feature parameters may also be determined by obtaining instructions input by a user, or by obtaining image recognition captured by a vehicle-mounted camera, and so on.

[0143] In addition, an embodiment of the present invention further proposes a storage medium, on which a pressure regulating program for a vehicle door sealing strip is stored. When the pressure regulating program for a vehicle door sealing strip is executed by a processor, the relevant steps of any embodiment of the pressure regulating method for a vehicle door sealing strip as described above are implemented.
