The inventor researches and discovers that the existing method for reducing the door closing force by controlling the lifting of the car window mainly has the following technical problems:
first, the opening degree of control door window can not be nimble in prior art, along with the increase of vehicle live time, perhaps when the vehicle is in different ambient conditions, the door window probably need be opened to different positions, just can reach the effect that reduces the door closing force, and the equal unified control door window is opened to the same position under various conditions, and under a lot of circumstances, probably can't reach the effect of better reduction door closing force.
Secondly, this kind of mode of prior art does not consider under sleet weather, and in the in-process that reduces the door closing force, sleet probably is squeezed into the car in through the window of opening, drenches the interior article of car, reduces user's use and experiences.
Aiming at the problems existing in the prior art discovered by the research of the inventor, the embodiment of the application provides a system and a method for reducing the closing force of the vehicle door, which can effectively improve the use experience of a user; the system for reducing the closing force of the vehicle door will be briefly described below:
the system for reducing the closing force of the vehicle door comprises a vehicle door position sensor, a vehicle window lifting control device and an electronic barometer; the vehicle door position sensor is used for detecting the opening degree of a vehicle door and sending a detection result to the vehicle window lifting control device; the electronic barometer is used for detecting air pressure information when the vehicle door is opened within a preset time period and sending the air pressure information to the vehicle window lifting control device; the window lifting control device is used for determining the window opening degree according to air pressure information sent by the electronic barometer, and controlling the window to be opened according to the window opening degree under the condition that the detection result sent by the door position sensor represents that the door is opened. So, according to the atmospheric pressure change information that produces when opening the door in a period, adjust the door window degree of opening suitably to guarantee to open according to this door window degree of opening control door window, can reduce the power of closing the door effectively, improve user's use and experience.
The system for reducing the closing force of a vehicle door provided by the present application is described by way of example below:
referring to fig. 1, fig. 1 is a schematic structural diagram of a system for reducing a closing force of a vehicle door according to an embodiment of the present disclosure; as shown in fig. 1, the system for reducing the closing force of the door includes: a door position sensor 101, a window lift control device 102, and an electronic barometer 103.
The door position sensor 101 is configured to detect an opening degree of a door and send a detection result to the window lift control device 102.
The door position sensor 101 can sensitively detect the opening angle of the door, and when the detected opening angle indicates that the door is opened or closed, the door position sensor 101 can immediately send a corresponding detection result to the window regulator 102.
Optionally, the door position sensor may be a door switch, and the door switch is a micro switch disposed in the door, and may sense opening or closing of the door sensitively, and communicate with the window lift control device 102; when the vehicle door is slightly opened, the vehicle door switch can detect that the current vehicle door is opened, correspondingly generates a detection result for representing that the vehicle door is opened, and sends the detection result to the vehicle window lifting control device 102; when the door switch detects that the current door is closed, the door switch may generate a detection result indicating that the door is closed, and send the detection result to the window up-down control device 102.
And the electronic barometer 103 is used for detecting air pressure information when the vehicle door is opened within a preset time period and sending the air pressure information to the vehicle window lifting control device 102.
Along with the use of the vehicle, and mechanical structures such as the window lift control device 102 will be ageing deformation constantly, when closing the door, the window is controlled to open according to the fixed window opening degree all the time, and the effect of reducing the size of the closing force of the door may not be achieved.
The window lifting control device 102 is used for determining the opening degree of the window according to the air pressure information; and when the detection result represents that the vehicle door is opened, controlling the vehicle window to be opened according to the vehicle window opening degree.
After receiving the air pressure information sent by the electronic air pressure meter 103, the window lift control device 102 determines the window opening degree according to the air pressure information, for example, when the received air pressure information is larger than the previously received air pressure information, the window opening degree is controlled to be larger accordingly, and when the received air pressure information is smaller than the previously received air pressure information, the window opening degree is controlled to be smaller accordingly.
Therefore, when the detection result sent by the door position sensor 101 is received and the door is represented to be opened, the window lifting control device 102 can correspondingly control the window to be opened according to the determined window opening degree; furthermore, when receiving the detection result sent by the door position sensor 101 and indicating that the door is closed, the window lift control device 102 may control the window to be closed accordingly.
Optionally, the window lift control device 102 may include: anti-pinch lifters and Body Controls (BCM); the BCM is used for determining the opening degree of a vehicle window according to air pressure information and sending a control instruction to the anti-pinch lifter when the detection result represents that the vehicle door is opened; the anti-pinch lifter is used for responding to the control instruction and controlling the opening of the car window according to the opening degree of the car window. During specific implementation, the BCM can determine the opening degree of the car window according to air pressure information sent by the electronic barometer; furthermore, under the condition that the detection result represents that the vehicle door is opened, a first control instruction is sent to the anti-pinch lifter; and sending a second control instruction to the anti-pinch lifter under the condition that the detection result represents that the vehicle door is closed.
After receiving the detection result sent by the door position sensor 101, the BCM correspondingly generates a control instruction according to the detection result, and sends the generated control instruction to the anti-pinch lifter. Specifically, when the detection result received by the BCM represents that the vehicle door is opened currently, the BCM correspondingly generates a first control instruction for controlling the vehicle window to be opened and sends the first control instruction to the anti-pinch lifter; when the detection result received by the BCM indicates that the vehicle door is closed currently, the BCM correspondingly generates a second control instruction for controlling the vehicle window to be closed and sends the second control instruction to the anti-pinch lifter.
The anti-pinch lifter 102 is used for controlling the opening of the car window according to the first control instruction and the car window opening degree determined by the BCM; and controlling the car window to be closed according to a second control instruction.
If the anti-pinch lifter receives a first control instruction for controlling the opening of the car window, which is sent by the BCM, the anti-pinch lifter correspondingly controls the opening of the car window according to the car window opening degree determined by the BCM; if the anti-pinch lifter receives a second control instruction for controlling the car window to be closed, which is sent by the BCM, the anti-pinch lifter correspondingly controls the car window to be closed.
The anti-pinch lifter can be specifically an electric vehicle window lifter working based on a Hall principle or a ripple principle, has an electric anti-pinch function, and can effectively prevent a user from being pinched; in addition, this prevent pressing from both sides riser still possesses the door window position and detects the function, can accurately detect the position of door window based on this function to judge whether the door window has been closed tightly (whether the door window has pushed into the guide slot completely promptly), and control the door window and open to the door window degree of opening.
And the vehicle window lifting control device is also used for controlling the vehicle window according to the manual operation triggered by the user on the vehicle window when detecting that the manual operation triggered by the user on the vehicle window is triggered in the process of controlling the vehicle window to be opened and closed.
In addition, in the process of controlling the opening and closing of the vehicle window, if it is detected that the user triggers manual operation on the vehicle window, for example, the user manually adjusts the opening and closing amplitude of the vehicle window; at this time, the window lift control device 102 may stop controlling the window to open or close, i.e., the window is no longer automatically controlled to close, and the user controls the window.
It should be noted that the seal structure of the door may be configured in a shape with different thicknesses, as shown in fig. 2, in the seal, a position near the upper portion of the door frame is thicker, and the lower portion is thinner; after the vehicle window descends, a certain wedge-shaped gap is generated between the vehicle window and the sealing strip, and the gap becomes larger and larger along with the descending of the vehicle window. When this sealing strip can guarantee that the door window is closed, can realize its inseparable laminating to reduce the noise that the door window was closed. In addition, when the window is automatically descended to reduce the closing force of the door, and the window is descended to a thinner area, the phenomenon that rain and snow enter the vehicle can be effectively prevented in rainy and snowy days while the gas flow is realized and the closing force of the door is reduced; the size of the cross section area of the inside and outside circulation of the vehicle can be controlled by adjusting the position of the vehicle window, so that the closing force of the vehicle door is adjusted.
Optionally, the system may further include: a rain and snow sensor and/or a weather information acquisition module; the rain and snow sensor is used for detecting whether rain and/or snow are present and sending a weather detection result to the window lifting control device 102; the weather information acquisition module is used for acquiring weather information through a network; correspondingly, the window lifting control device is also used for determining whether to control the window to be opened according to the window opening degree under the condition that the detection result represents that the vehicle door is opened according to the weather detection result and/or the weather information.
Specifically, the rain and snow sensor can detect whether rain and/or snow are present, and correspondingly send a weather detection result determined by the rain and snow sensor to the vehicle window lifting control device; the weather information acquisition module can acquire the weather information through a network.
When the system only comprises the rain and snow sensor, the vehicle window lifting control device can directly determine whether to control the vehicle window to be opened according to the vehicle window opening degree when detecting that the vehicle door is opened according to the weather detection result sent by the rain and snow sensor and the weather control logic preset by a user. When only including weather information acquisition module in the system, door window lift controlling means can be directly according to the weather information that weather information acquisition module sent and the weather control logic that the user presetted, confirm when detecting that the door is opened, whether control the door window according to door window opening degree and open. When the system simultaneously comprises the rain and snow sensor and the weather information acquisition module, the vehicle window lifting control device can combine the information sent by the rain and snow sensor and the weather information acquisition module to determine whether to control the vehicle window to be opened according to the vehicle window opening degree when detecting that the vehicle door is opened according to the weather control logic preset by a user.
It should be noted that the preset weather control logic may be set by a user, that is, the user may determine whether to reduce the door closing force by opening the window in rainy and snowy weather according to the actual requirement of the user, and if the weather control logic set by the user is that the door closing force is not reduced by opening the window in rainy and snowy weather, the window lift control device does not control the window to be opened in rainy and snowy weather, and otherwise, if the weather control logic set by the user is that the door closing force is reduced by opening the window in rainy and snowy weather, the window lift control device still controls the window to be opened according to the window opening degree determined by the window lift control device in rainy and snowy weather.
The above system for reducing a door closing force includes: the device comprises a vehicle door position sensor, a vehicle window lifting control device and an electronic barometer; the vehicle door position sensor is used for detecting the opening degree of a vehicle door and sending a detection result to the vehicle window lifting control device; the electronic barometer is used for detecting air pressure information when the vehicle door is opened within a preset time period and sending the air pressure information to the vehicle window lifting control device; the window lifting control device is used for determining the window opening degree according to air pressure information sent by the electronic barometer, and controlling the window to be opened according to the window opening degree under the condition that the detection result sent by the door position sensor represents that the door is opened.
