Description

A METHOD FOR REDUCING BUFFETING OF A WINDOW BY A WINDOW DEVICE AS WELL AS A CORRESPONDING WINDOW DEVICE
FIELD OF THE INVENTION
[0001] The invention relates to the field of automobiles. More specifically, the invention relates to a method for reducing buffeting of a window of a motor vehicle by a window device of the motor vehicle as well as to a corresponding window device.
BACKGROUND INFORMATION
[0002] When air is forced into a closed interior, for example into an interior of a motor vehicle, the pressure inside the interior of the motor vehicle slightly increases. When the pressure outside the interior decreases, the air inside the interior will flow back out. As air is forced across an opening of an interior, air will initially be forced into the interior. Then, as the internal pressure increases, it is forced back out of the interior, which lowers the internal pressure to allow air to be forced into the interior again.
[0003] US 7895036 B2 discloses a voice enhancement logic for improving the perceptional quality of a processed voice. The voice enhancement system includes a noise detector and a noise attenuator. The noise detector detects a wind buffet and a continuous noise by modelling the wind buffet. The noise attenuator dampens the wind buffet to improve the intelligibility of an unvoiced, a fully voiced, or a mixed voice segment.
[0004] There is a need in the art to provide a method as well a window device that can reduce the buffeting of a window when air is forced into the interior of the motor vehicle.

[0008] Therefore, an enhanced comfortable cabin experience is realized without requiring explicit user interaction of a user of the motor vehicle.
[0009] In particular, in multi-occupant road trips is the state of the windows is often disused between the occupants. In addition to the temperature and increased road noise levels, having the windows in different open/close states may cause a pressure effect, known as side window buffeting. This may cause loud, unpleasant, and periodic noise that is bothersome to occupants of the motor vehicle. As a result, such occupants are forced to roll down or roll up their window somewhat to reduce the unpleasant noise.
[0010] Therefore, in an embodiment, a pressure relief device is presented, which allows pressure equalization at a different point to improve the Helmholtz resonance. This point is likely to be, but not limited to being, in the vicinity of each window.
[0011] In an embodiment, the pressure relief device is a door and depending on a negative pressure on one side of a flexible diaphragm as the pressure detection device the door is opened to lower the pressure.
[0012] In a further embodiment, the pressure detection device comprises a plurality of electronic pressure sensors, which are arranged around the motor vehicle, and the pressure is determined by an electronic computing device of the window device and the electronic computing device generates a control signal for actuating the pressure relief device.
[0013] In a still further embodiment, the window device comprises an electronic computing device, wherein the electronic computing device comprises a mathematical model, wherein depending on at least one characterizing parameter of the motor vehicle the mathematical model determines the pressure and depending on the determined pressure the pressure relief device is actuated.
[0014] In another embodiment, the window device comprises an electronic computing device, wherein the electronic computing device comprises a machine learning algorithm and the machine learning algorithm is analyzing at least one characterizing parameter of the motor vehicle and the machine learning algorithm determines the pressure and depending on the determined pressure, the pressure relief device is actuated.
[0015] A further aspect of the invention relates to a window device to reduce buffeting of a window of a motor vehicle, comprising at least one pressure detection device and one pressure relief device, wherein the devices configured to perform a method according to the preceding aspect. In particular, the method is performed by the device.

This embodiment is described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
[0025] Fig. 1 shows an embodiment of a motor vehicle 10 comprising a window device 12. The window device 12 is configured to reduce buffeting of a window 14 of the motor vehicle 10. The window device 12 comprises one pressure detection device 16 and one pressure relief device 18.
[0026] According to an embodiment, a method is provided to reduce buffeting of the window 14 of the motor vehicle 10 by the window device 12, wherein a pressure inside the motor vehicle 10 and/or outside 20 the motor vehicle 10 is detected by the pressure detection device 16 of the window device 12 and depending on the detected pressure the pressure relief device 18 of the window device 12 is actuated to lower the pressure inside the motor vehicle 10.
[0027] In an embodiment the pressure relief device 18 is a door and depending on a negative pressure on one side of a flexible diaphragm 30 of the pressure detection device 16 the door is opened to lower the pressure. Therefore, a mechanical embodiment of the window device 12 is provided. In this embodiment, the pressure detection device 16 is a physical element, which actuates the pressure relief device 18. A negative pressure on one side of the flexible diaphragm 30 causes the diaphragm 30 to flex, actuating the door between a cabin space of the motor vehicle 10 and the external environment. As the pressure changes, so does the flexion actuator, until the pressure is equalized.
[0028] In another embodiment, the pressure detection device 18 comprises a plurality of electronic pressure sensors 22 which are arranged around the motor vehicle 10, and the pressure is determined by an electronic computing device 24 of the device 12 and the electronic computing device 24 generates a control signal for actuating the pressure relief device 18. The electronic pressure sensors 22 may arranged outside and inside of the motor vehicle 10. For example the electronic pressure sensors 22 may arranged in the vicinity of the window 14. Therefore, an electronic embodiment of the device 12 is presented, wherein the electronic pressure sensor 22 are placed around the motor vehicle 10. These electronic pressure sensors 22 are connected to the electronic computing device 24 by a vehicle control bus [IN, CAN or Ethernet, which is also connected to remote actuators that perform the same function as in the mechanical embodiment. In this and further embodiments, the pressure relief device 18 may be the window 14 itself, actuated electronically. This embodiment allows for fine tuning via software, including remote updates provided over the air to the motor vehicle 10 in the field, and reduces the mechanical complexity compared to the previous embodiment.
[0029] In another embodiment the window device 12 may comprise the electronic computing device 24, wherein the electronic computing device 24 comprises a mathematical model 26, wherein depending on at least one characterizing parameter 28 of the motor vehicle 10 the mathematic model 26 determines the pressure and depending on the determined pressure the pressure relief device 18 is actuated. In this embodiment, rather than explicitly determining the pressure differential between different parts of the motor vehicle 10, the mathematic model 26 is generated that provides an assumed pressure differential given various input variables. These variables, which are shown as the characterizing parameter 28, include but are not limited to the current speed of the motor vehicle 10, the state of all windows 14, including the degree to which the window 14 is down, rather than just a binary state, and the location of the current occupants in the motor vehicle 10. It should be appreciated that this embodiment simplifies the previous embodiments by reducing mechanical complexity as well as the electronic sensors.
[0030] In a further embodiment, the window device 12 comprises the electronic computing device 24, wherein the electronic computing device 24 comprises a machine learning algorithm 30 and the machine learning algorithm 30 is analyzing at least one characterizing parameter 28 of the motor vehicle 10 and the machine learning algorithm 30 predicts the pressure and depending on the determined pressure the pressure relief device 18 is actuated. This embodiment uses the machine learning algorithm 30 to determine a particular user sensitivity to window buffeting and reacts appropriately. Specifically, if the immediate response to the window 14 being lowered is that another window 14 is lowered either partially or fully, the machine learning algorithm 30 takes note of this and correlates it with various input features, such as the location of the current motor vehicle 10, date and time, location, among others. This information builds the machine learning algorithm 30 that informs the system when to actuate the pressure relief device 18, which may or may not be another window 14. This embodiment has the advantage of the modelled embodiment, which is described in the upper part, however does not require explicit construction of models for each motor vehicle 10. It also takes into account user preferences, for example that the users that do not experience a discomfort will not trigger the feature, and in the case that a window 14 or other user-actionable pressure relief system is used, the user may provide corrective action to the system by reversing the action, for example closing the window 14 manually.
[0031] The figures shows a reduction of side window buffeting using machine learning algorithm 30.
