Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, not all, embodiments of the present invention.
At present, in view of the problem that the existing vehicle window control technology has low user experience, in order to improve the problem, the vehicle window control method and device and the unmanned vehicle provided by the embodiment of the invention can be applied to improving the user experience.

And S102, acquiring vehicle interior information by using the first sensor and acquiring vehicle exterior information by using the second sensor.
The first sensor may be fixed to an edge of the target window and form a certain angle with the window glass, so as to detect vehicle interior information of the vehicle in which the target window is located (i.e. the inside condition of the target window), and the first sensor may be a camera, an infrared sensor or a light sensor. Correspondingly, the second sensor may be fixed to an edge of the target window at a certain angle with respect to the window glass, so as to detect vehicle external information of the vehicle in which the target window is located (i.e. the outside condition of the target window), and the second sensor may be a camera, an infrared sensor or a light sensor.
And step S104, controlling the target window based on the vehicle interior information and the vehicle exterior information.
Because the vehicle internal information comprises the vehicle window inner side condition of the target vehicle window, and the vehicle external information comprises the vehicle window outer side condition of the target vehicle window, the vehicle window is controlled according to the comprehensive information of the vehicle window inner side and the vehicle window outer side, the misjudgment of abnormal conditions can be avoided, and the accuracy of vehicle window control is improved.
For example, when a first sensor detects a foreign object (such as a passenger's hand) on the inside of the window of a target window and a second sensor does not detect a foreign object on the outside of the window of the target window, it can be determined that the passenger's hand is at the window but not protruding outside the window, anti-pinch control can be performed on the window without a safety warning prompt; when the first sensor detects that there is the foreign matter in the door window inboard of target door window, and the second sensor also detects the door window outside of target door window when having the foreign matter, can confirm that there is the foreign matter to stretch out outside the window, can carry out anti-pinch control to the door window to carry out the warning suggestion of safety.
According to the vehicle window control method provided by the embodiment, the two sensors are arranged on the target vehicle window, the vehicle internal information located on the inner side of the vehicle window and the vehicle external information located on the outer side of the vehicle window can be simultaneously acquired, the acquired vehicle information is more comprehensive, the vehicle window is automatically controlled based on the vehicle internal information and the vehicle external information, the vehicle window safety control of the unmanned vehicle can be realized, the unmanned driving safety is improved, and the user experience is further improved in the automatic driving process of the unmanned vehicle.
In order to improve the accuracy of window control, the first sensor and the second sensor that this embodiment provided set up in target door window top, and first sensor and second sensor become the contained angle of predetermineeing the angle. The first sensor and the second sensor can share the same mounting point, see the sensor position schematic diagram shown in fig. 2, fig. 2 shows a side view of the vehicle door 21 and the vehicle window 22, the first sensor 23 and the second sensor 24 can be arranged on the top of the edge of the vehicle window 22, and the first sensor 23 and the second sensor 24 form an included angle of a preset angle (the included angle of the preset angle can be set according to the maximum detection angle of the sensors, so that the vehicle window can be shot by both the first sensor and the second sensor), the mounting point of the first sensor 23 on the top of the edge of the vehicle window 22 and the mounting point of the second sensor 24 on the top of the edge of the vehicle window 22 are the same mounting point, and the arrangement position is hidden, so that the aesthetics of the vehicle is not affected. In practical applications, the mounting points of the first sensor 23 and the second sensor 24 may be provided with a rotatable device, so that the angle between the first sensor 23 and the second sensor 24 can be adjusted manually or automatically.
In the existing window control technology, referring to the existing sensor position schematic diagram shown in fig. 3, the existing window foreign matter detection sensor 31 is disposed directly above the window, and the number of the sensors is one, and the sensor can only detect window information, however, when the foreign matter detection sensor 31 fails, it is impossible to detect whether a foreign matter exists above the window, and the reliability of window control is low.
In this application, the detection range of the first sensor 23 includes the interior of the vehicle and the glass top of the target window, and the detection range of the second sensor 24 includes the exterior of the vehicle and the glass top of the target window (preferably, the two sensors can indicate the detection results from different ranges, such as the detection results of the glass top, the detection results of the exterior or the detection results of the interior are respectively indicated). The first sensor 23 and the second sensor 24 can simultaneously detect the information inside the vehicle, the information of the vehicle window and the information outside the vehicle, when one of the sensors breaks down, the other sensor can still detect whether a foreign object exists above the vehicle window, safety warning is carried out, and the reliability of vehicle window control is improved. Moreover, the first sensor 23 and the second sensor 24 can share one mounting point, and compared with the prior art, a new sensor mounting point does not need to be processed, and the installation is convenient.

The air pollution index inside the vehicle is detected by the first sensor, the air pollution index outside the vehicle is detected by the second sensor, when the air pollution index inside the vehicle is larger than the air pollution index outside the vehicle, namely the quality of the air outside the vehicle is better than that of the air inside the vehicle, and when the quality of the air outside the vehicle is smaller than a preset pollution index (namely the quality of the air outside the vehicle is better), the vehicle window is controlled to be opened, so that the air pollution index inside the vehicle is reduced, and the quality of the air inside the vehicle is improved.
The preset pollution index may be set according to the age of the vehicle occupant, such as a smaller value when the vehicle occupant is an old person or a child, and a larger value when the vehicle occupant is an adult, and may be, for example, any value between 50 and 150.
And 2, step: and when the air pollution index inside the automobile is smaller than the air pollution index outside the automobile, controlling the target automobile window to be in a window closing state. When the air quality inside the vehicle is better than the air quality outside the vehicle, the control target window is closed and remains closed in order to prevent the air quality inside the vehicle from being degraded.
And 3, step 3: and when the air pollution index inside the vehicle and the air pollution index outside the vehicle are both larger than the preset pollution index, controlling the vehicle where the target vehicle window is located to start fresh air circulation. When the air quality inside the vehicle and the air quality outside the vehicle are poor, in order to improve the air quality inside the vehicle, the target vehicle window can be controlled to be closed, a fresh air circulating system of the vehicle is started, pollutants inside the vehicle are removed, the air inside the vehicle is purified, and the air quality inside the vehicle is improved.

When a vehicle is in driving and a window is opened, an internal image acquired by a first camera and an external image acquired by a second camera are acquired in real time or at preset time intervals, the internal image and the external image are subjected to image detection respectively, when the detection result of the internal image is that a foreign matter exists above the glass of the window (the foreign matter can be other objects except the window glass or human body parts such as hands, heads or other objects of passengers), and the detection result of the external image is that the foreign matter exists above the glass of the window, the foreign matter exists above the glass of a target window is determined, in order to ensure the safety of the passengers, anti-pinch control is performed on the target window, and a safety prompt is issued to remind the passengers of withdrawing the foreign matter of the window. Above-mentioned anti-pinch control can be when the control door window is closed, if it has the foreign matter to detect the door window top, stop control door window closes. The safety prompt can be one or more of a voice prompt, an alarm sound prompt and an indicator light prompt.
In order to improve the safety of the automatic driving of the unmanned vehicle, the vehicle window control method provided by the embodiment further comprises the following steps a to c:
and a, performing portrait recognition on the internal image to obtain a target passenger portrait in the vehicle.
