[0029] Example 1

[0030] Figure 1 A flowchart of a smart dimming glass control method is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the smart dimming glass is controlled based on the facial status of the occupant obtained by an infrared camera. The method can be executed by a smart dimming glass control device, which can be implemented in the form of hardware and / or software. The smart dimming glass control device can be configured in any electronic device with network communication function. Figure 1 As shown, the method includes:

[0031] S110: Determine whether a passenger is sitting in the target seat based on image data acquired by an infrared camera in the cabin.

[0032] An infrared camera may be a device that emits infrared light to illuminate an object. The infrared light is diffusely reflected by the object and then received by the surveillance camera, thereby forming a video image. In embodiments of the present invention, the infrared camera may be configured as a vehicle infrared camera, and image data obtained by the infrared camera may be used to determine whether a passenger is seated in a target seat.

[0033] The target seat may refer to any seat in the vehicle, such as the main driver's seat, the co-driver's seat, or the back seat. The passenger may refer to the driver or other passengers.

[0034] In one alternative embodiment of the present invention, large vehicles, such as buses, typically have two or three adjacent seats near the windows. If infrared cameras are only installed for the seats near the windows, one or two seats adjacent to the windows may still be exposed to light. Therefore, infrared cameras are required for one or two seats adjacent to the windows to determine whether there are passengers in the one or two seats adjacent to the windows. In other words, in this embodiment of the present invention, infrared cameras are required for all seats in the vehicle, allowing passengers in any seat to control the light transmittance of the windows.

[0035] S120: After determining that a passenger is seated in the target seat, turn on the target intelligent dimming glass controller associated with the target seat, and use a light intensity sensor to obtain the current light intensity outside the vehicle window.

[0036] Smart dimming glass refers to a type of laminated glass made by placing a dimming liquid crystal film between two layers of glass, which is then bonded together under high temperature and pressure in an autoclave or laminating furnace. This is a new type of specialty optoelectronic glass product. The liquid crystal dimming film switches instantly between transparent (on) and foggy (off) when powered. In embodiments of the present invention, the vehicle windows are made of smart dimming glass, and the transmittance of the windows is controlled by controlling the smart dimming glass.

[0037] The target smart dimming glass controller may refer to a device that controls the smart dimming glass. The target smart dimming glass controller is connected to an infrared camera and receives image data from the infrared camera to determine whether a passenger is occupying a target seat. If a passenger is seated, the target smart dimming glass controller is automatically activated to control the light transmittance of the vehicle window.

[0038] Optionally, the target smart dimming glass controller can also directly obtain image data from the infrared camera from the bus to determine whether there is a passenger in the target seat and control the light transmittance of the window when there is a passenger. The infrared camera needs to transmit the detected image data information to the bus.

[0039] The light intensity sensor may be a sensor mounted on the side of a vehicle window that detects the intensity of light outside the window. The light intensity sensor collects the intensity of light outside the vehicle window in real time and transmits the collected light intensity to a bus. The target smart dimming glass controller adjusts the transmittance of the smart dimming glass based on the collected light intensity.

[0040] S130: Compare the current light intensity with a preset light intensity threshold, and use the target smart dimming glass controller to adaptively adjust the transmittance of the smart dimming glass at the target seat.

[0041] The current light intensity obtained by the light intensity sensor is compared with a preset light intensity threshold, and when the current light intensity exceeds the preset light intensity threshold, the target smart dimming glass controller is used to adaptively adjust the transmittance of the smart dimming glass at the target seat.

[0042] Optionally, for large vehicles such as buses, there are usually two or three adjacent positions near the windows. When there are passengers sitting in any of these two or three positions, the transmittance of the smart dimming glass of the window can be controlled.

[0043] An embodiment of the present invention provides a method for controlling smart dimming glass. This method determines whether a target seat is occupied based on image data captured by an infrared camera within the cabin. Upon determining that a passenger is occupied in the target seat, the target smart dimming glass controller associated with the target seat is activated, and a light intensity sensor is used to obtain the current light intensity outside the vehicle window. The current light intensity is then compared with a preset light intensity threshold, allowing the target smart dimming glass controller to adaptively adjust the light transmittance of the smart dimming glass at the target seat. Using the technical solution of this embodiment of the present invention, a corresponding control strategy is implemented for the smart dimming glass based on the comparison result between the current light intensity obtained in real time and the preset light intensity threshold, ensuring an optimal user experience for passengers.

[0044] Example 2

[0045] Figure 2 This is a flow chart of a smart dimming glass control method provided by the second embodiment of the present invention. The embodiment of the present invention further optimizes the above embodiment on the basis of the above embodiment. The embodiment of the present invention can be combined with various optional solutions in one or more of the above embodiments. Figure 2 As shown, the method includes:

[0046] S210: Determine whether the target seat is occupied based on image data acquired by the infrared camera in the cabin.

[0047] Among them, an infrared camera is equipped in the vehicle cabin, and the infrared camera is used to detect whether there is an occupant sitting in the target seat.

[0048] As an optional but non-limiting implementation, determining whether a target seat is occupied based on image data acquired by an infrared camera in the cabin includes but is not limited to steps A1-A2:

[0049] Step A1: An infrared camera is configured in the target seat, and the infrared camera is connected to the target intelligent dimming glass controller.

[0050] Step A2: Acquire image data captured by the infrared camera to determine whether there is an occupant sitting in the target seat; wherein, when there is an occupant sitting in the target seat, the presence of the occupant can be detected in the image data captured by the infrared camera.

[0051] Among them, an infrared camera is equipped in the cabin of the vehicle, and the infrared camera is connected to the target smart dimming glass controller so that the data obtained by the infrared camera is transmitted to the target smart dimming glass controller.

[0052] In the embodiment of the present invention, image data from an infrared camera is used to determine whether there is an occupant sitting in the target seat.

[0053] S220: After determining that a passenger is seated in the target seat, turn on the target intelligent dimming glass controller associated with the target seat, and use a light intensity sensor to obtain the current light intensity outside the vehicle window.

[0054] Among them, after determining that there is a passenger in the target seat and the passenger controls the transmittance of the smart dimming glass through the intelligent soft switch, the target smart dimming glass controller associated with the target seat is turned on, and the light intensity sensor is used to obtain the current light intensity outside the window.

[0055] As an optional but non-limiting implementation, the method further includes but is not limited to steps B1-B3:

[0056] Step B1: Setting a soft switch on the central control screen of the target seat; wherein the soft switch includes an intelligent soft switch and a manual soft switch.

[0057] Step B2: When the occupant of the target seat selects the manual soft switch, the soft switch is manually adjusted to adaptively select the transmittance.

[0058] Step B3: When the occupant of the target seat does not select any soft switch within the preset time threshold, the intelligent soft switch is automatically triggered, and the transmittance of the intelligent dimming glass at the target seat is adaptively adjusted through the target intelligent dimming glass controller.

[0059] Among them, an intelligent soft switch and a manual soft switch are set on the central control screen of the target seat; when the passenger sits in the target seat and determines from the central control screen that the transmittance of the intelligent dimming glass is controlled by the manual soft switch, the soft switch is manually adjusted to determine the appropriate transmittance.

[0060] If the passenger sits in the target seat and determines from the central control screen that the transmittance of the smart dimming glass is controlled through the smart soft switch, the target smart dimming glass controller associated with the target seat can be turned on, and the transmittance of the smart dimming glass can be controlled according to the current light intensity obtained by the light intensity sensor to keep the light intensity at a comfortable state.

[0061] Optionally, if the passenger is sitting in the target seat and does not select any soft switch to control the transmittance of the smart dimming glass within a preset time threshold, the smart soft switch will be automatically triggered, and the transmittance of the smart dimming glass at the target seat will be adaptively adjusted through the target smart dimming glass controller.

[0062] In the embodiment of the present invention, a soft switch is set to allow passengers to select the corresponding soft switch according to their needs, allowing passengers to choose their preferred transmittance state; at the same time, a preset time threshold is set so that after the passenger has sat in the target seat for a certain period of time, the target smart dimming glass controller automatically turns on to automatically control the transmittance at the target seat.

[0063] S230: Compare the current light intensity with a preset light intensity threshold, and use the target smart dimming glass controller to adaptively adjust the transmittance of the smart dimming glass at the target seat.

[0064] Among them, when the passenger controls the transmittance of the smart dimming glass through the smart soft switch, the current light intensity obtained is compared with the preset light intensity threshold, and the target smart dimming glass controller is used to control the transmittance of the smart dimming glass at the target seat.

[0065] As an optional but non-limiting implementation, comparing the current light intensity with a preset light intensity threshold to adaptively adjust the transmittance of the smart dimming glass at the target seat using the target smart dimming glass controller includes but is not limited to steps C1-C4:

[0066] Step C1: disposing a light intensity sensor on a side window of a vehicle and connecting the light intensity sensor to a target smart dimming glass controller; wherein the material of the side window of the vehicle is smart dimming glass.

[0067] Step C2: comparing the current light intensity acquired by the light intensity sensor with a preset light intensity threshold.

[0068] Step C3: If the current light intensity is less than the preset light intensity threshold, the target smart dimming glass controller is used to adaptively enhance the light transmittance of the smart dimming glass at the target seat.

[0069] Step C4: If the current light intensity is greater than the preset light intensity threshold, the target smart dimming glass controller is used to adaptively reduce the transmittance of the smart dimming glass at the target seat.

[0070] Among them, in an embodiment of the present invention, a light intensity sensor is configured on the side window of the vehicle, and the light intensity sensor is connected to the target smart dimming glass controller. The target smart dimming glass controller controls the transmittance of the smart dimming glass at the target seat through the current light intensity transmitted by the light intensity sensor.

[0071] The preset light intensity threshold set in the embodiment of the present invention can refer to a most comfortable light intensity (δ0), which is taken from the light intensity that makes people most comfortable on a clear summer day without direct sunlight. The light intensity sensor obtains the current light intensity (δ) outside the window of the target seat; when (δ<δ0), the light intensity is not strong, and the smart glass controller adjusts the light transmittance of the smart dimming glass at the target seat to the maximum, allowing all light to enter; when (δ>δ0), the system determines that the current light intensity has exceeded the optimal comfortable state and adjusts the light transmittance of the smart dimming glass at the target seat to maintain the light intensity entering the vehicle through the smart dimming glass at approximately δ0.

[0072] In an alternative embodiment of the present invention, if there are occupants in adjacent seats, and all occupants use manual soft switches to control the window transmittance, the transmittance can be adjusted based on the set transmittance. For example, the transmittances adjusted by the manual soft switches can be compared, and the lowest transmittance can be set as the final window transmittance; or the transmittance adjusted first using the manual soft switch can be used as the final transmittance.

[0073] In an alternative solution of an embodiment of the present invention, if there are passengers in adjacent seats, and one passenger uses a manual soft switch and the other passenger uses an intelligent soft switch, the transmittance of the intelligent dimming glass is adaptively adjusted according to the target intelligent dimming glass controller.

[0074] In the embodiment of the present invention, by comparing the current light intensity with the preset light intensity threshold, the target smart dimming glass controller is used to adaptively adjust the transmittance of the smart dimming glass at the target seat, so that the light intensity entering the vehicle is maintained at an optimal state, providing a good user experience for the passengers.

[0075] S240: Detecting passenger facial expressions.

[0076] Among them, after using the target intelligent dimming glass controller to adaptively adjust the transmittance of the intelligent dimming glass at the target seat, the infrared sensor is continuously used to obtain the facial expression of the occupant to determine whether the adjusted transmittance meets the needs of the occupant.

[0077] As an optional but non-limiting implementation, the method for detecting occupant facial expressions specifically includes but is not limited to steps D1-D2:

[0078] Step D1: Real-time detection of the occupant's facial expression, and after determining that the occupant is feeling uncomfortable, using the target smart dimming glass controller to adaptively reduce the transmittance of the smart dimming glass at the target seat; wherein, factors determining that the occupant is feeling uncomfortable include the occupant blocking light with his hands or the occupant's eyes are in a closed state.

[0079] Step D2: Alternatively, if it is detected that the occupant's eyes are closed and the duration is greater than a first preset time threshold, the target smart dimming glass controller is used to adjust the transmittance of the smart dimming glass at the target seat to a target transmittance, and the target smart dimming glass controller automatically stops controlling the smart dimming glass; wherein the target transmittance refers to the transmittance at the lowest state.

[0080] Among them, the facial expressions of the passengers are detected in real time to determine whether the adjusted transmittance meets the needs of the passengers; and after determining that the passengers are feeling uncomfortable, the target intelligent dimming glass controller is used to adaptively adjust the transmittance of the intelligent dimming glass at the target seat. For example, if the passenger uses his hands to block the light, it can be determined that the passenger is feeling uncomfortable, and the target intelligent dimming glass controller is used to adaptively reduce the transmittance of the intelligent dimming glass at the target seat. If it is detected that the passenger's eyes are in a closed state, the target intelligent dimming glass controller can be used to adaptively reduce the transmittance of the intelligent dimming glass at the target seat so that the passenger can rest better. Optionally, the detection of the passenger's facial expressions can be trained by identifying the eyeballs and facial relaxation using deep learning methods, and has the ability to judge the passenger's comfort level. There is no specific limitation on the detection of the passenger's facial expressions in the embodiments of the present invention.

[0081] Among them, if it is detected that the occupant's eyes are closed and the duration is greater than a first preset time threshold, it can be determined that the occupant has entered a nap state, and the target smart dimming glass controller is used to adjust the transmittance of the smart dimming glass at the target seat to the lowest state; and the target smart dimming glass controller is turned off to drive the smart dimming glass to save energy.

[0082] As an optional but non-limiting implementation, the occupant facial expression detection further includes:

[0083] When it is detected that the passenger's eye state changes from closed eyes to open eyes, and the duration of the open eyes state is greater than a second preset time threshold, the control of the smart dimming glass by the target smart dimming glass controller is automatically restored, and the transmittance of the smart dimming glass at the target seat is adaptively controlled according to the light intensity outside the car window.

[0084] Among them, an infrared sensor is used to continuously detect the occupant in the target seat. When it is detected that the occupant's eye state changes from a closed eye state to an open eye state, and the duration of the open eye state is greater than a second preset time threshold, the target smart dimming glass controller automatically restores the control of the smart dimming glass to adaptively adjust the transmittance of the smart dimming glass to meet the new needs of the occupant.

[0085] As an optional but non-limiting implementation, the method further includes: when it is determined that there is no passenger at the target seat, automatically turning off the target smart dimming glass controller and setting the transmittance of the smart dimming glass at the target seat to an original state; wherein the original state refers to a transmittance state corresponding to a preset light intensity threshold.

[0086] When it is determined that there is no passenger in the target seat, the target smart dimming glass controller is automatically turned off, and the transmittance of the smart dimming glass at the target seat is in the original state; the original state refers to the transmittance state corresponding to the preset light intensity threshold, that is, δ0. Optionally, the passenger seating state at the target seat is monitored, and when it is determined that the time when there is no passenger in the target seat is greater than a first preset time threshold, the target smart dimming glass controller is automatically turned off. After the passenger leaves the target seat, the target smart dimming glass controller is not immediately turned off, so as to avoid frequent closing and opening of the target smart dimming glass controller when a passenger leaves and then immediately takes the seat, causing damage to the target smart dimming glass controller.

[0087] In the embodiment of the present invention, when the target seat is unoccupied, the driving control of the target smart dimming glass controller is turned off, which can achieve the effect of both saving energy and extending the service life of the smart dimming glass.

[0088] An embodiment of the present invention provides a method for controlling smart dimming glass. By equipping the cabin with a light intensity sensor and an in-cabin infrared camera, the system acquires information about occupant occupancy, facial status, and current external light intensity, creating a real-time control system for the smart dimming glass. By acquiring occupant facial information, the system can be adjusted in a closed loop to maintain optimal light intensity. Occupants can also adjust light transmittance to achieve privacy or personalization. When the cabin is unoccupied or a passenger is taking a nap, the system automatically disables control of the smart dimming glass, providing a positive passenger experience while also saving energy and extending the life of the smart dimming glass.
