[0006] In some implementations, determining that a target user intends to get out of the vehicle based on the target user's state includes: monitoring the vehicle's seat pressure signal when the target user is detected turning; and determining that the target user intends to get out of the vehicle when a change in the seat pressure signal is detected and the target user is detected performing an operation on the door handle.

[0007] In some implementations, determining that a target user intends to get out of the vehicle based on the target user's state includes: acquiring the target user's visual vector and the target user's body movement information; and determining that the target user intends to get out of the vehicle when the visual vector remains in the target direction for a preset time and the body movement information indicates that the target user has a body movement moving in the target direction, wherein the target direction is the direction towards the vehicle door or the direction towards the rearview mirror on the side of the vehicle door.

[0008] In some implementations, if the target user intends to get out of the vehicle, the window control method further includes: controlling the window to close when it is detected that the target user has gotten out of the vehicle and the door is closed.

[0009] In some implementations, acquiring the vehicle's environmental signal includes: acquiring a first frame environmental image and a second frame environmental image of the vehicle; determining the difference value of pixels at the same position in the first frame environmental image and the second frame environmental image; determining the ratio of a first quantity to a second quantity as a salt-and-pepper noise value; the first quantity being the number of pixels with a difference value greater than a difference threshold, and the second quantity being the number of pixels included in the first frame environmental image or the second frame environmental image; and determining the salt-and-pepper noise value as snowfall.

[0010] In some embodiments, acquiring environmental signals of the vehicle includes: collecting rainfall data via a rain sensor, wherein the rain sensor includes a capacitive rain sensor and an infrared scattering rain sensor.

[0011] In some embodiments, the correspondence between the amount of rain and snow and the amount of window opening includes: the correspondence between the amount of rain and the amount of window opening, the correspondence between the amount of snow and the amount of window opening, and the correspondence between the amount of rain and snow and the amount of window opening.

[0012] Secondly, embodiments of this disclosure provide a vehicle window control device, comprising: a monitoring module for monitoring the state of a target user corresponding to the vehicle; an acquisition module for acquiring environmental signals of the vehicle and signals of objects held by the target user when the target user's state indicates an intention to get in or out of the vehicle; and a control module for performing a window control action on the vehicle when the environmental signal indicates rain or snow and the signal of objects held indicates that the target user is holding an umbrella; wherein the window control action includes at least one of the following: in response to determining that the target user intends to get in the vehicle, controlling the vehicle door and the window of the door to open, and controlling the window to close after detecting that the target user has gotten in the vehicle and put the umbrella in the vehicle; the vehicle door is a frameless door; or in response to determining that the target user intends to get out of the vehicle, controlling the window to open before controlling the door to open.

[0021] The technical solutions of the embodiments of this disclosure will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure are within the scope of protection of this disclosure.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this disclosure can be implemented in orders other than those illustrated or described herein, and that the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The following description, in conjunction with the accompanying drawings, details the window control method, device, vehicle, medium, and product provided in this disclosure through specific embodiments and application scenarios.

[0024] Figure 1 is a schematic flowchart of a window control method provided in an embodiment of this disclosure, which is applied to a vehicle. As shown in Figure 1, the window control method includes the following steps S100 to S300.

[0025] Step S100: Monitor the status of the target user corresponding to the vehicle.

[0026] In this embodiment of the disclosure, the target user is a user waiting to board or alight from the vehicle. In the boarding scenario, the target user is a user whose distance from the vehicle is less than a preset distance. In the alighting scenario, the target user is any user already in the vehicle. The state of the target user may include, but is not limited to, their action state.

[0027] Step S200: If it is determined from the target user's state that the target user has the intention to get on or off the vehicle, acquire the vehicle's environmental signals and the target user's handheld object signals.

[0028] In this embodiment of the disclosure, the behavioral intent of a target user can be determined by monitoring the target user's state. The target user's behavioral intent may include, but is not limited to, the intent to get on the vehicle and the intent to get off the vehicle.

[0029] In this embodiment, the intention of a target user to get out of the vehicle can be determined based on the target user's visual vector state signal or the vehicle's seat pressure signal. In one example, when the user's upper body is detected turning towards the side of the vehicle, the change in seat pressure caused by the turning process is collected. The change in seat pressure, combined with the signal of pulling or pressing the door handle, can determine that the target user intends to get out of the vehicle. In another example, if the user's visual vector remains in the side door or the rearview mirror area on the side of the vehicle for more than a preset time, and body movement information indicates that the target user is moving towards the side door or the rearview mirror area on the side of the vehicle, the intention of the target user to get out of the vehicle can be determined. Specifically, the body movement information could be that the target user is holding an umbrella and their body is showing a tendency to extend the umbrella out of the vehicle. In yet another example, the intention of the target user to get out of the vehicle can also be determined when a door opening action signal is detected.

[0030] In this embodiment of the disclosure, a camera configured outside the vehicle, such as an Advanced Driver Assistance Systems (ADAS) camera, can be used to determine the target user's intention to get into the vehicle when the distance between the user and the vehicle continues to decrease, combined with signals such as pulling or pressing the door handle.

[0031] In this embodiment of the disclosure, when it is determined that the target user intends to get on or off the vehicle, environmental signals of the vehicle and signals of the target user's handheld object are acquired. The environmental signals of the vehicle may include, but are not limited to, rain and snow signals.

[0032] In this embodiment of the disclosure, rainfall signals can be acquired using a rain sensor. The rain sensor may include, but is not limited to, capacitive rain sensors and infrared scattering rain sensors. In one example, when using an infrared scattering rain sensor for rainfall detection, the intensity of light reflected back to the sensor receiver from the glass can be used to determine whether it is raining and the amount of rainfall.

[0033] In this embodiment of the disclosure, snowfall signals can be determined by combining environmental images captured by a camera with cloud-based weather data. In one example, the amount of snowfall can be determined by obtaining the salt-and-pepper noise content in the environmental image.

[0034] In this embodiment of the disclosure, the handheld object signal can be used to identify the user's handheld object through the Occupancy Monitoring System (OMS) camera configured inside the vehicle.

[0035] Step S300: When the environmental signal indicates the presence of rain or snow, and the handheld object signal indicates that the target user is holding an umbrella, perform a window control action on the vehicle.

[0036] As can be seen, in this embodiment of the disclosure, when the target user has the intention to get on or off the vehicle, and the environmental signal indicates the presence of rain or snow, and the handheld object signal indicates that the target user is holding an umbrella, the control action on the vehicle window can be performed. It should be noted that this embodiment of the disclosure does not limit the execution order of determining the intention to get on or off the vehicle, obtaining the vehicle's environmental signal and the target user's handheld object signal. The execution order of the method embodiment corresponding to Figure 1 is only an example. In other embodiments, the execution order of determining the intention to get on or off the vehicle, obtaining the vehicle's environmental signal and the target user's handheld object signal may also be to first obtain the vehicle's environmental signal and the target user's handheld object signal, and then determine the target user's intention to get on or off the vehicle.

[0037] In one example, when a target user intends to get into the vehicle, the system controls the opening of the nearest door and the door's window. In some embodiments, the window can be opened and closed by raising and lowering it; in others, it can be opened and closed by moving it left and right. The window can be frameless, and the vehicle door and its window can open simultaneously, or the door can open after the window has opened. After detecting that the target user has entered the vehicle, the system continues to recognize the user's body language. If the target user is still holding an umbrella, the window remains open. If the target user puts the umbrella away in the vehicle, the window can be closed.

[0038] In another example, if the target user intends to get out of the vehicle, the window on the target user's side is opened first. After the window is opened, the door on the target user's side is opened. Once the target user has completed getting out of the vehicle and a door-closing signal is received, the window can be closed.

[0039] Through steps S100-S300, the status of the target user corresponding to the vehicle is first monitored. If the target user's status indicates an intention to get in or out of the vehicle, the vehicle's environmental signals and the target user's handheld object signal are acquired. If the environmental signal indicates rain or snow, and the handheld object signal indicates the target user is holding an umbrella, a window control action is executed. This window control action may include, but is not limited to: opening the vehicle door and its window if the target user intends to get in, and closing the window after detecting that the target user has entered and placed their handheld object inside; or opening the vehicle window before opening the vehicle door if the target user intends to get out. Thus, by automatically controlling the windows based on rain / snow signals and the user's handheld object signal when the user intends to get in or out of the vehicle, users can open their umbrellas before getting in or out, reducing the probability of getting wet in rain or snow during the process and improving the user experience.

[0040] In some implementations, performing window control actions on a vehicle includes: acquiring a correspondence between rainfall / snowfall and window opening amount; determining a target window opening amount corresponding to the rainfall or snowfall indicated by an environmental signal in the correspondence; and performing window control actions on the vehicle based on the opening amount.

[0041] Specifically, the rainfall and snowfall amounts were first collected at multiple gear levels, and experiments were conducted to determine the corresponding window opening amounts for each gear level. Through these experiments, the optimal window opening amounts for each gear level were determined. Based on these optimal values, the correspondence between rainfall / snowfall amounts and window opening amounts at different gear levels was established.

[0042] The correspondence between rainfall and snowfall and the amount of car windows opened may include, but is not limited to, the correspondence between rainfall and the amount of car windows opened, the correspondence between snowfall and the amount of car windows opened, and the correspondence between rainfall and snowfall and the amount of car windows opened.

[0043] Based on the correlation between rainfall / snowfall and window opening levels, the window opening level corresponding to the rainfall / snowfall indicated by the environmental signal can be determined, i.e., the target window opening level. This target window opening level is then defined as the window opening level, and the window is controlled to open based on this level.

[0044] By controlling the opening of car windows based on the correlation between the amount of rain and snow and the amount of window opening, the opening amount of the windows can be matched according to the specific environmental conditions, improving the adaptability of the window opening range and thus reducing the probability of users getting wet in the rain or snow when getting in and out of the car.

[0045] In some implementations, determining that a target user intends to get out of the vehicle based on the target user's state includes: monitoring the vehicle's seat pressure signal when the target user is detected turning; and determining that the target user intends to get out of the vehicle when a change in the seat pressure signal is detected and the target user is detected performing an operation on the door handle.

[0046] Specifically, when a target user intends to get out of the vehicle, they will rotate their upper body to a position that facilitates exiting. This rotation will cause a change in the seat pressure zone. Therefore, the vehicle's seat pressure signal can be monitored when the target user's rotation is detected. Based on the monitored seat pressure signal, it can be determined whether the seat pressure signal has changed. If a change in the seat pressure signal is detected, and the target user is observed to be interacting with the door handle, it can be determined that the target user intends to get out of the vehicle. In one example, the target user's interaction with the door handle may include, but is not limited to, pulling or pressing the door handle.

[0047] By determining the user's intention to get out of the vehicle based on the user's rotation and seat pressure signals, the accuracy of determining the intention to get out of the vehicle can be improved.

[0048] In some implementations, determining that a target user intends to get out of the vehicle based on the target user's state includes: acquiring the target user's visual vector and the target user's body movement information; and determining that the target user intends to get out of the vehicle when the visual vector remains in the target direction for a preset time and the body movement information indicates that the target user has a body movement moving in the target direction, wherein the target direction is the direction towards the vehicle door or the direction towards the rearview mirror on the side of the vehicle door.

[0049] Specifically, the view vector can be understood as the direction vector representing the observer's perspective. The target user's view vector can be acquired through a DMS (Driver Monitor System) camera installed inside the vehicle. The target user's body language information may include, but is not limited to, hand gestures. In one example, the body language information could be that the target user is holding an umbrella and their body is showing a tendency to extend the umbrella out of the vehicle. The target direction could be towards the door or towards the rearview mirror on the side of the door. If the target user's view vector remains in the direction towards the door or the rearview mirror on the side of the door for more than a preset time, and the body language information indicates that the target user is moving towards the side door or the rearview mirror area on the side of the door, it can be determined that the target user is paying attention to the lateral space and has the intention to get out of the vehicle.

[0050] By determining the user's intention to get off the vehicle based on the user's gaze vector, dwell time, and body movement information, the comprehensiveness of the determination of the intention to get off the vehicle can be improved.

[0051] In some implementations, if the target user intends to get out of the vehicle, the window control method further includes: controlling the window to close when it is detected that the target user has gotten out of the vehicle and the door is closed.

[0052] Specifically, upon detecting that the target user has completed disembarking and receiving a door-closing signal, it indicates that the target user and their umbrella have completely left the vehicle and the door is closed. At this point, the window can be closed. By controlling the window to close only after the target user has disembarked and closed the door, the probability of the target user getting wet during disembarkation can be reduced, as can the probability of water entering the vehicle.

[0053] In some implementations, acquiring the vehicle's environmental signal includes: acquiring a first frame environmental image and a second frame environmental image of the vehicle; determining the difference value of pixels at the same location in the first frame environmental image and the second frame environmental image; determining the ratio of a first quantity to a second quantity as a salt-and-pepper noise value; the first quantity is the number of pixels whose difference value is greater than a difference threshold, and the second quantity is the number of pixels included in the first frame environmental image or the second frame environmental image; and determining the salt-and-pepper noise value as snow volume.

[0054] Specifically, snowfall can be determined by obtaining salt-and-pepper noise values ​​in environmental images. Salt-and-pepper noise is a common type of image noise, manifested as randomly appearing black and white dots in an image. The value of salt-and-pepper noise usually refers to the intensity or probability of noise occurrence, typically expressed as a noise ratio (such as a value between 0 and 1). The higher the noise ratio, the more significant the noise effect.

[0055] First, a first frame and a second frame of environmental images of the vehicle are acquired using an image acquisition device, such as a camera. Differential calculations are performed on pixels at the same location in both the first and second environmental images to determine the difference values. Salt-and-pepper noise typically causes significant pixel value variations in the differential results. Therefore, these large variations can be identified by setting a differential threshold. The ratio of the number of pixels with differential values ​​greater than the threshold to the total number of pixels in either the first or second environmental image is defined as the salt-and-pepper noise value. Since the salt-and-pepper noise value of the environmental image can represent the snowfall amount, it can be used to determine the snowfall amount.

[0056] In this embodiment, determining the snowfall amount by measuring the salt-and-pepper noise value of the vehicle's environmental image can improve the accuracy of snowfall determination.

[0057] Figure 2 illustrates a window control system provided in an embodiment of this disclosure. As shown in Figure 2, firstly, a calibration matrix is ​​established, that is, the correspondence between rain / snowfall and window opening amount in this disclosure is calibrated. After determining the correspondence through the calibration matrix, the correspondence is stored in the control system for use in controlling the window raising and lowering based on the correspondence. Secondly, vehicle hardware configuration is required, which may include equipping the vehicle with a sunlight and rain sensor, an external vehicle camera, and a cloud-based weather data acquisition device for multi-directional weather perception during window control.

[0058] In practical applications, to achieve window control, the first step is to perform vehicle weather perception. Specifically, this can be achieved through vehicle hardware configuration, such as using a sunlight and rain sensor to collect rainfall data, external vehicle cameras to capture environmental images, and cloud-based weather data. Then, based on the rainfall, environmental images, and cloud-based weather data, weather perception is performed to determine the amount of rain or snow.

[0059] After determining the amount of rain and snow through vehicle weather sensing, the system identifies whether the user is carrying an umbrella. Specifically, this can be done by detecting whether the user is holding an object and whether that object is an umbrella.

[0060] When identifying users getting on and off the vehicle, methods such as visual recognition, pressure recognition, and door opening signal judgment can be used. A single recognition method or a combination of methods can be employed to determine the user's intention to get off. In one example, based on visual recognition, the user's visual vector and limb movement can be used to determine if the user intends to get off. If the user's visual vector remains on the side door or the rearview mirror area for a certain period of time, and the user's limbs turn towards the side door or the rearview mirror area, then the user can be determined to have the intention to get off. In another example, based on pressure recognition, changes in seat pressure can be used to determine the user's intention to get off. In yet another example, the door opening signal can be used directly to determine if the user intends to get on or off.

[0061] After determining the user's intention to get in or out of the vehicle, the window is lowered. First, upon receiving a door opening signal, vehicle parameters are retrieved, specifically the pre-calibrated correspondence between rainfall / snowfall and window opening levels. The window lowering operation is then controlled via the window control system. Specifically, if the target user intends to get in, the nearest door and its window are opened according to the calibration relationship. The window can be frameless; the vehicle door and its window can open simultaneously, or the door can open after the window has opened. After detecting that the target user has boarded, the system continues to recognize the user's body language. If the target user is still holding an umbrella, the window remains open. If the target user puts their umbrella away, the window closes. If the target user intends to get out, the window on the target user's side is opened according to the calibration relationship, and then the target user's side door opens after the window has opened. Once the system detects that the target user has completed getting out of the vehicle and receives a door closing signal from the vehicle, it can control the windows to close.

[0062] By automatically lowering the window based on rain / snow signals and the user's handheld object when the user intends to get on or off the vehicle, users can open their umbrellas before getting on or off, reducing the probability of getting wet in the rain or snow during the process and improving the user experience.

[0065] The acquisition module 32 is used to acquire the vehicle's environmental signals and the target user's handheld object signals when it is determined from the target user's state that the target user has the intention to get on or off the vehicle.

[0067] The window control action includes at least one of the following: in response to determining that the target user intends to get into the vehicle, controlling the vehicle door and the window of the door to open, and controlling the window to close after detecting that the target user has gotten into the vehicle and put the umbrella in the vehicle; the vehicle door is a frameless door; in response to determining that the target user intends to get out of the vehicle, controlling the window to open before controlling the door to open.
