Description

Vehicle window control system and method thereof

Technical Field

The present invention relates to control of vehicle accessories, and more particularly, to a window control system and method, and a computer storage medium storing a computer program that implements the window control method when executed.

Background

With the popularization of private cars, the requirements of users on the supporting facilities and the humanized design of the vehicles are more and more complicated.

The common vehicle window control is that the lifting control of the window is realized by a mechanical structure or a combination of transmission of an electric signal and the mechanical structure. The general expression is as follows: when the car window is in a closed or semi-closed state, the car window descends all the time by long pressing any one car window control key of the car, and in the process of descending the car window, the car window stops descending immediately by releasing the car window control key; correspondingly, when the car window is in a semi-closed or fully-opened state, the control key of the car window is elongated, the car window is lifted all the time, and in the process of lifting the car window, the control key of the car window is released, and the car window stops lifting. Some other control methods for the vehicle window are as follows: when the car window is in a closed or semi-closed state, pressing the control key of the car window, enabling the car window to descend until the car window is completely opened, and in the process of descending the car window, triggering the control key of the car window again to enable the car window to stop descending; correspondingly, when the car window is in a semi-closed or fully-opened state, the control key of the car window is pulled down, the car window is lifted up until the car window is fully closed, and in the process of lifting the car window, the control key of the car window needs to be triggered again, so that the car window can be stopped from being lifted up.

The two control modes can exist independently or simultaneously. However, in any control method, if an obstacle exists on the lifting trajectory of the window while the window is being lifted, the window control mechanism does not stop lifting the window. The lift is stopped only when the obstacle is relatively firm and the control mechanism of the window cannot break through the obstacle. In this case, if the obstacle is any part of the human body, the window may cause damage to the human body. If the obstacle is another hard object, damage may be caused to the window glass.

Therefore, in order to prevent an accident that may be caused by the forced lifting of the control mechanism of the window when an obstacle exists on the lifting track of the window, it is necessary to provide a control system and a method thereof capable of intelligently controlling the window.

Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.

According to an aspect of the present invention, there is provided a window control system for preventing forcible lifting of a window when an obstacle exists on a lifting trajectory of the window.

In one embodiment, as shown in fig. 1, the window control system 100 includes a photographing module 110, an identifying module 120, and a control module 130.

The photographing module 110 is used for photographing an identification image, which is image data about a window of a vehicle that can be raised and lowered. The photographing module 110 at least requires that all the windows of the vehicle that can be raised and lowered can be photographed.

Specifically, the window control system 100 may include a shooting module 110, which can shoot all the liftable windows of the vehicle, and is installed on the front windshield or the rear windshield of the vehicle, for shooting the identification images of all the windows in the vehicle.

It is understood that the window control system 100 may also include a plurality of shooting modules 110, where the shooting modules are respectively used for shooting one or more liftable windows on a vehicle, and a combination of the shooting modules can shoot all the liftable windows on the vehicle.

Preferably, the window control system 100 includes 2 camera modules 110 respectively mounted on a front windshield and a rear windshield of the vehicle. The shooting module mounted on the front windshield is mainly used for shooting front windows of a vehicle, skylights arranged on a front roof and the like, and the shooting module mounted on the rear windshield is mainly used for shooting rear windows, skylights arranged on a rear roof and the like.

Further, the window control system 100 may further include a photographing module disposed on the rear view mirror. The rear-view mirror can include a left rear-view mirror and/or a right rear-view mirror, the shooting module installed on the left rear-view mirror is used for shooting one or more windows on the left side of the vehicle to obtain the identification image of the one or more windows on the left side, and the shooting module installed on the right rear-view mirror is used for shooting one or more windows on the right side of the vehicle to obtain the identification image of the one or more windows on the right side.

"liftable window" broadly refers to any openable and closable window or roof, etc. on a vehicle.

Since the identification image is used to determine whether an obstacle exists in the lifting area of the window included in the identification image, when the photographing module 110 photographs any one or more windows, an angle formed by the photographing direction and the plane where the lifting track of the window is located should be smaller than 90 ° so as to determine whether the obstacle exists in the lifting area based on the lifting area of the window and the plane where the obstacle exists.

The recognition module 120 is coupled to the photographing module 110, and is configured to acquire a recognition image of the window that is started to be raised, and perform image recognition on the acquired recognition image to determine whether an obstacle exists in a lifting area of the window that is started to be raised.

The window glass is provided with a visible boundary running track, and the window glass is provided with a visible boundary running track.

Alternatively, when there are a plurality of windows in any one identification image acquired by the identification module 120, the identification image may be divided in advance according to a certain rule, and the identification images are respectively divided into identification images including only one window. The certain rule may be a rule of a corresponding position of each window in the identification image, which is determined based on shooting parameters such as a shooting position and a shooting angle of the identification image.

It is understood that the identification module 120 may acquire the identification image of any window in the non-closed state in response to that the window is in the non-closed state, that is, when there is a gap in the lifting area of the window. Preferably, the identification module 120 may acquire the identification image of the window lifted by the start to perform identification in response to the control key of any one window being pressed, that is, the window is lifted by the start.

It can be understood that, in any one of the operations of acquiring the identification image, the identification module 120 may acquire the identification images of all the windows indiscriminately, or may acquire only some of the identification images of the windows. The indiscriminate identification images of all windows are acquired, so that the matching mechanism between the windows and the identification images is reduced, and the cost is reduced. The accuracy of the acquired identification image is increased by only acquiring the identification images of part of the windows, so that the identification images can be processed uniformly, and the complexity of data processing is reduced.

Specifically, the image data of the window in the closed state and the open state when the window is in the unmanned state in the vehicle can be used as the image boundary of the window. And comparing the image characteristics of the identification image to judge whether an obstacle is close to the image boundary of the vehicle window, and judging that the obstacle exists in the lifting area of the vehicle window when the image boundary of the vehicle window is broken by any obstacle or is infinitely close to the obstacle.

Further, the image recognition may be performed by a neural network algorithm, a template matching method, a geometric transformation method, and other image recognition methods that can recognize the positional relationship between the obstacle and the window lifting area in the recognized image.

The control module 130 is coupled to the recognition module 120 and generates an alert signal in response to the recognition module 120 determining that an obstacle is present in a lift zone of a window that is activated to lift, the alert signal being intended to trigger the window in the lift zone in which the obstacle is present to stop lifting to prevent an accident.

Further, in some embodiments, the warning message may be a warning message for reminding the user to stop lifting the window with the obstacle or reminding the vehicle occupant to notice the vehicle being pinched.

Specifically, the reminding message may be an expression content similar to "the left front window (right front window, left rear window, right rear window or skylight) has a foreign object, does not lift up" or "the left front window (right front window, left rear window, right rear window or skylight) is lifting up, wary of being clipped".

Furthermore, the form of presentation of the reminder message may be an audio reminder message or a virtual screen reminder message.

The audible alert message may be a voice message played through a speaker controlling the vehicle. The virtual picture reminding information can be a virtual picture which displays the content corresponding to the reminding information through a central control display screen of the vehicle so as to intuitively show that the obstacle exists in the lifting area of the vehicle window.

In addition, in some highly automated vehicles, the warning signal may be a window control signal for controlling the lift mechanism of the corresponding window to stop raising, inhibit raising, or lower to a fully open state.

In the case that the automation degree of the vehicle is high, the control module 130 may be a vehicle body controller, and when the identification module 120 determines that an obstacle exists in the lifting area of any window, the vehicle body controller generates a window control signal to control the corresponding window with the obstacle to stop lifting, prohibit lifting, or fall to a fully opened state.

In other cases, the photographing module 110, the recognition module 120, and the control module 130 may exist in any combination integrated in one device or may exist separately formed in one device. The device and the equipment can be arranged on the vehicle, or can be equipped on the vehicle.

According to another aspect of the present invention, there is provided a window control method for preventing forcible lifting of a window when an obstacle exists on a lifting trajectory of the window.

In one embodiment, as shown in fig. 2, the window control method 200 includes steps S210 to S230.

Wherein, step S210 is: and acquiring an identification image of the vehicle window which is started to lift.

The identification image is image data about a window that can be raised and lowered on the vehicle.

The "acquiring" may be acquiring from a shooting device provided on the vehicle, such as a shooting device installed on a front windshield or a rear windshield of the vehicle for shooting identification images of all windows in the vehicle, or multiple shooting devices respectively provided at different positions on the vehicle for shooting identification images of corresponding windows.

Preferably, in step S210, the identification image of the window in the non-closed state may be acquired in response to that any one of the windows is in the non-closed state, that is, when there is a gap in the lifting area of the window.

Alternatively, step S210 may acquire the identification image of the window that is lifted up in response to the control key of any one window being pressed, that is, the window is lifted up.

Further, in any one of the operations of acquiring the identification image, the identification images of all the windows may be acquired without distinction, or only the identification images of some of the windows may be acquired. The indiscriminate identification images of all windows are acquired, so that the matching mechanism between the windows and the identification images is reduced, and the cost is reduced. The accuracy of the acquired identification image is increased by only acquiring the identification images of part of the windows, so that the identification images can be processed uniformly, and the complexity of data processing is reduced.

Step S220 is: and identifying the acquired identification image to judge whether an obstacle exists in the lifting area of the started and lifted vehicle window.

Specifically, the image data of the window in the closed state and the open state when the window is in the unmanned state in the vehicle can be used as the image boundary of the window.

Further, step S220 includes step S221: and comparing the image characteristics of the identification images to judge whether the identification images are close to the image boundary of the vehicle window, and judging that an obstacle exists in a lifting area of the vehicle window with the image boundary being exceeded when the image boundary of the vehicle window is exceeded by any identification image.

Alternatively, when a plurality of windows exist in any one of the acquired identification images, the identification image may be divided in advance according to a certain rule, and the identification images are respectively divided into identification images including only one window. The certain rule may be a rule of a corresponding position of each window in the identification image, which is determined based on shooting parameters such as a shooting position and a shooting angle of the identification image.

Step S230 is: in response to the presence of an obstacle in the lifting area of any window that is activated to lift, an alert signal is generated that is intended to trigger the stopping of the lifting of the window in the lifting area in the presence of an obstacle to prevent an accident.
