DETAILED DESCRIPTION
[0024] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to specific embodiments and drawings.

[0026] As described in the background section, with the continuous development of intelligence and individualization, atmosphere lamps are increasingly used in modern vehicles, and atmosphere lamps have become an important function to improve the driving experience. Atmosphere lamps are important elements to improve user experience and add driving pleasure and comfort. Therefore, the development demand of atmosphere lamps cannot be limited to the basic functions of atmosphere lamps, and atmosphere lamps should not only have a decorative function, but also have a practical function.
[0027] Applicant found in the process of realizing the present application that whether it is necessary to release formaldehyde after new car purchase or it is caused by carelessness after opening the window in summer, it is easy to cause rainwater to enter the car due to the car window being forgotten to be closed in the rainy season in summer, and a good car becomes a "waterlogged car". In view of this problem, in the related art, a sunshine rainfall sensor is configured, the commonly used sunshine rainfall sensor is an optical rainfall sensor, the size of rainfall is judged by rain hitting the sensor to cause the reflectivity of the sensor to change, and then information is fed back to a car window control system to automatically raise the car window to prevent the vehicle from being damaged due to the car window being forgotten to be closed. However, the sunshine rainfall sensor can cause misjudgment or delayed reaction, the sensor can cause misjudgment of the current state due to the influence of the arrangement position, the size and distribution of rainfall, and the sensor cannot automatically raise the window; the sunshine rainfall sensor also needs to be regularly cleaned and maintained, dirt, water accumulation or frost can affect the sensing effect of the sensor; the sensor is affected by electromagnetic environment and in some extreme weather such as heavy fog, snow and the like, the accuracy of the sensor is affected, and the sensor also has the risk of damage, so that the function is limited and the car window cannot be automatically raised.
[0028] Therefore, the present application can detect the humidity in the cabin of the target vehicle, make the car window of the target vehicle perform the operation of being raised or lowered, achieve a suitable environment climate in the cabin, improve the aesthetic appearance in the cabin and improve the user experience.
[0029] The car window control system, the car window control method and the automobile according to the embodiments of the present application are described below with reference to the drawings.
[0030] Reference Figure 1 is a structural schematic view of the car window control system according to some embodiments of the present application.
[0031] As Figure 1 shown, the car window control system 100 of the present application can include a vehicle-mounted RGB atmosphere lamp 10 capable of detecting humidity and a controller 20.
[0032] Further, in order to solve the problem of single function of the current vehicle-mounted RGB atmosphere lamp, the vehicle-mounted RGB atmosphere lamp 10 capable of detecting humidity of the present application can detect the humidity in the cabin of the target vehicle, and then judge the dryness and humidity in the cabin to meet the multi-dimensional needs of users.
[0033] In some embodiments, with reference Figure 2 to a top view schematic view of the arrangement area of the vehicle-mounted RGB atmosphere lamp capable of detecting humidity according to some embodiments of the present application, the vehicle-mounted RGB atmosphere lamp 10 capable of detecting humidity can start from the instrument panel in the car, with reference Figure 3For the isometric view of the arrangement area of the vehicle-mounted RGB atmosphere lamp capable of detecting humidity according to some embodiments of the present application, the atmosphere lamp is arranged along a circle along the car column, the ceiling, and the back of the car. It can also be arranged below the front of the driver's seat and the front passenger's seat, and the foot space of the rear passengers. Or arranged in the area surrounding the gear lever (shift knob), inside the cup holder, inside the mobile phone wireless charging slot, inside the armrest box, or the edge.
[0034] Further, the controller 20 is connected with the vehicle-mounted RGB atmosphere lamp capable of detecting humidity 10, and the controller 20 can control the target vehicle window to perform the lifting or lowering operation according to the humidity, so as to make the environment in the car compartment reach the suitable humidity. For example, when the humidity in the car compartment is large, the target vehicle window is controlled to perform the lifting operation to prevent raindrops or fog outside the window from entering the car compartment and avoid the humidity in the car compartment from continuing to increase; when the humidity in the car compartment is small, the target vehicle window is controlled to perform the lowering operation to make the outside environment enter the car compartment.
[0035] The vehicle-mounted RGB atmosphere lamp capable of detecting humidity 10 can be a vehicle-mounted RGB atmosphere lamp capable of detecting humidity based on Mach-Zehnder interference. Mach-Zehnder (Mach-Zehnder interferometer) is a device that works by using the principle of light interference. The core idea is: divide a beam of light into two paths, let them propagate along different paths, experience different physical environments, and then recombine. By observing the interference of the light after recombination (brightening or darkening), the slight difference between the two paths of light experienced by the environment is accurately measured.
[0036] Further, referring to Figure 4 For the internal structure diagram of the vehicle-mounted RGB atmosphere lamp capable of detecting humidity according to some embodiments of the present application, the vehicle-mounted RGB atmosphere lamp capable of detecting humidity 10 can include a laser emitter 11, a fiber channel 14, and a photodetector 13.
[0037] Specifically, the laser emitter 11 can emit laser light, wherein the laser emitter 11 can be an RGB laser emitter, the emission wavelength of the RGB laser emitter is 1550 nm, and the RGB laser emitter has RGB three-color laser emitters. The RGB laser emitter as an atmosphere lamp light source can realize a multi-color RGB light source with good coherence and high brightness, so that the atmosphere lamp realizes 64 colors, 128 colors, or even more colors.
[0038] Specifically, the optical fiber channel 14 is arranged in the target vehicle cabin, and the optical fiber channel 14 sequentially comprises a first single-mode optical fiber 141, a first hollow optical fiber 142, a detection single-mode optical fiber 143, a second hollow optical fiber 144, and a second single-mode optical fiber 145. The detection single-mode optical fiber 143 can be a tapered optical fiber, and the surface of the detection single-mode optical fiber 143 is coated with a humidity-sensitive material, wherein the humidity-sensitive material is a graphene film humidity-sensitive material. The incident end of the first single-mode optical fiber 141 is connected with the laser emitter 11, so that the laser emitted by the laser emitter 11 first passes through the first single-mode optical fiber 141.
[0039] Specifically, the photodetector 13 is connected with the outgoing end of the second single-mode optical fiber 145, so that the photodetector 13 can receive the laser emitted through the second single-mode optical fiber 145. The photodetector 13 can detect the transmission spectrum intensity of the laser passing through the optical fiber channel 14, that is, the photodetector 13 can receive the transmission spectrum intensity of the interference fringes.
[0040] Further, the vehicle-mounted RGB atmosphere lamp 10 capable of detecting humidity can further comprise a data storage interaction module 12, which can analyze the transmission spectrum intensity to analyze the humidity in the target vehicle cabin.
[0041] Further, referring to Figure 5 For a schematic diagram of an optical fiber according to some embodiments of the present application, the optical fiber can comprise a core layer, a cladding layer, and a coating layer.
[0042] Referring to Figure 6 For a schematic diagram of the diffusion of the coreless layer of the second hollow optical fiber to the cladding layer according to some embodiments of the present application, the laser emitted from the laser emitter 11 will simultaneously pass through the core layer and the cladding layer when passing through the region from the first single-mode optical fiber 141 to the first hollow optical fiber 142, and evanescent waves will be generated. It can be understood that the laser is transmitted by total reflection in the core layer of the optical fiber, and when transmitted from the core layer of the first single-mode optical fiber 141 to the first hollow optical fiber 142, the laser is transmitted to the cladding layer due to the absence of the core layer of the first hollow optical fiber 142, forming evanescent waves. The evanescent waves will be coupled when passing through the region from the second hollow optical fiber 144 to the second single-mode optical fiber 145, and the interference fringes will be formed when entering the second single-mode optical fiber 145. The interference fringes change due to the change of humidity, and the change of the interference fringes can be used to obtain the change of the humidity in the target vehicle cabin.
[0043] When the relative humidity in the environment increases, the humidity-sensitive material coated on the surface of the detection single-mode optical fiber 143 can absorb water in the air. After the humidity-sensitive material absorbs water vapor, the effective refractive index of the detection single-mode optical fiber 143 changes, thereby changing the transmission spectrum intensity of the laser passing through the optical fiber passage 14, i.e., causing the spectral intensity of the cladding mode transmitted in the optical fiber to change, the evanescent field energy radiated outward increases, thereby causing the transmission spectrum intensity of the laser passing through the optical fiber passage 14 to decrease, i.e., causing the spectral intensity of the cladding mode to decrease, but the spectral intensity of the core mode remains unchanged, so the transmission spectrum intensity of the sensor decreases. The change in spectral intensity (i.e., the change in the stripe) can determine the change in the relative humidity of the surrounding environment.
[0044] The spectral intensity of the interference can be determined according to the following formula:
[0045] wherein, represents the spectral intensity of the interference; represents the light intensity of the core mode; represents the light intensity of the cladding mode; represents the phase difference when the core mode and the cladding mode interfere.
[0046]
[0047] wherein, is the central wavelength of the laser; represents the difference between the effective refractive indices of the core mode and the cladding mode, ; represents the length of the optical fiber; represents the effective refractive index of the core mode; represents the effective refractive index of the cladding mode.
[0048] When , the spectral intensity of the interference reaches a minimum value, and a trough of interference occurs.
[0049] According to the relationship between the above formula and , the wavelength of the trough can be obtained:
[0050] wherein, represents the wavelength of the trough. Due to the change in the interference stripe, the central wavelength of the trough is shifted. By demodulating the amount of shift of the central wavelength, the current humidity change can be measured.
[0051] During the testing of the sensor, assuming that the external temperature is constant, when the humidity conditions of the surrounding environment change, the relative humidity sensitivity of the sensor can be determined by the following formula: wherein, represents the relative humidity sensitivity; represents the light intensity of the core mode; represents the light intensity of the cladding mode; represents the difference between the effective refractive index of the core mode and the cladding mode.
[0052] In summary, according to the vehicle window control system of the embodiment of the present application, the vehicle-mounted humidity-detectable RGB atmosphere lamp is used to detect the humidity in the vehicle cabin of the target vehicle, the controller is connected with the vehicle-mounted humidity-detectable RGB atmosphere lamp and is used to control the vehicle window of the target vehicle to perform the lifting or lowering operation according to the humidity. Thus, the system can detect the humidity in the vehicle cabin of the target vehicle, make the vehicle window of the target vehicle perform the lifting or lowering operation, achieve the suitable environmental climate in the vehicle cabin, improve the aesthetic appearance in the vehicle cabin, and improve the user experience.
[0053] Reference Figure 7 is a flowchart of the vehicle window control method according to some embodiments of the present application.
[0054] As Figure 7 shown, the vehicle window control method of the embodiment of the present application can include the following steps: S701, acquiring the transmission spectrum intensity detected by the photodetector in the target vehicle, and determining whether the transmission spectrum intensity is lower than a first preset intensity threshold. The first preset intensity threshold can be calibrated according to the actual situation.
[0055] Specifically, the photodetector detects the transmission spectrum intensity in real time, compares the real-time collected transmission spectrum intensity with the first preset intensity threshold, and determines whether the transmission spectrum intensity is lower than the first preset intensity threshold.
[0056] S702, in response to the transmission spectrum intensity being lower than the first preset intensity threshold, determining that the humidity in the vehicle cabin of the target vehicle is out of standard, and controlling at least one vehicle window of the target vehicle to perform the lifting operation.
[0057] Specifically, when the transmission spectrum intensity is lower than the first preset intensity threshold, it can be indicated that the vehicle window of the target vehicle is in the open state, and the target vehicle is in a humid environment such as rain or heavy fog. At this time, the humidity in the vehicle cabin may rise due to air circulation, it is determined that the humidity in the vehicle cabin of the target vehicle is out of standard, and at least one vehicle window of the target vehicle is controlled to perform the lifting operation, so as to prevent the humid environment such as rain or heavy fog from entering the vehicle cabin of the target vehicle. Thus, the automatic window lifting function in rainy and foggy days can be realized through humidity detection, the traditional sunlight and rainfall sensor is replaced, and the problem that the traditional sensor has a failure risk in complex extreme environments is solved.
[0058] In some embodiments of the present application, the above-mentioned vehicle window control method further comprises: in response to the transmittance spectrum intensity being not lower than the first preset intensity threshold, determining whether the transmittance spectrum intensity is higher than a second preset intensity threshold; in response to the transmittance spectrum intensity being higher than the second preset intensity threshold, determining that the humidity in the vehicle cabin of the target vehicle is insufficient, and controlling at least one vehicle window of the target vehicle to perform a lowering operation. The second preset intensity threshold can be calibrated according to actual conditions.
[0059] Specifically, when the transmittance spectrum intensity is not lower than the first preset intensity threshold, the transmittance spectrum intensity is compared with the second preset intensity threshold to determine whether the transmittance spectrum intensity is higher than the second preset intensity threshold. When the transmittance spectrum intensity is higher than the second preset intensity threshold, it can be indicated that the vehicle window of the target vehicle is in a closed state, and the target vehicle is in a dry external environment, and the humidity in the vehicle cabin of the target vehicle is insufficient. At this time, the humidity in the vehicle cabin can be increased by opening the vehicle window, that is, at least one vehicle window of the target vehicle is controlled to perform a lowering operation, so that the air of the external environment enters the vehicle cabin to achieve a suitable environmental climate in the vehicle cabin.
[0060] In some embodiments of the present application, the above-mentioned vehicle window control method further comprises: in response to determining that the humidity in the vehicle cabin of the target vehicle is insufficient, controlling to start a humidification system in the vehicle cabin of the target vehicle to humidify the vehicle cabin of the target vehicle.
[0061] Specifically, when it is determined that the humidity in the vehicle cabin of the target vehicle is insufficient, the humidification system in the vehicle cabin of the target vehicle is controlled to start, wherein the humidification system can be an ultrasonic humidifier, which can avoid the influence of water mist condensation on the line of sight. The humidification amount of the humidification system can be dynamically adjusted according to the number of people in the vehicle. The vehicle cabin of the target vehicle is humidified by the linkage of the humidification system, so as to realize the balance of dry and wet humidity in the vehicle cabin and achieve a suitable environmental climate in the vehicle cabin.
[0062] In some embodiments of the present application, before controlling at least one vehicle window of the target vehicle to perform a raising operation, the above-mentioned method further comprises: acquiring a gear signal of the target vehicle through a body controller, and determining whether the target vehicle is in a parking state according to the gear signal; in response to the target vehicle not being in the parking state, prohibiting the vehicle window of the target vehicle from performing a raising operation.
[0063] Specifically, before controlling the at least one window of the target vehicle to perform the lifting operation, first, the gear signal of the target vehicle is acquired by the body controller, if the gear signal of the target vehicle is in a non-parking gear (i.e. non-P gear), it is confirmed that the target vehicle is not in a parking state according to the non-parking gear, and the control of the window of the target vehicle to perform the lifting operation is prohibited to prevent misoperation from affecting driving safety. If the gear signal of the target vehicle is in a parking gear (i.e. P gear), it is confirmed that the target vehicle is in a parking state according to the parking gear, and the signal is fed back to the atmosphere lamp through the LIN (Local Interconnect Network) line.
[0064] In some embodiments of the present application, before controlling the at least one window of the target vehicle to perform the lifting operation, the above method further comprises: confirming whether there is a driver or passenger in the cabin of the target vehicle through the passenger detection system; and in response to the presence of a driver or passenger in the cabin of the target vehicle, controlling the voice prompt system to issue a voice prompt in the cabin of the target vehicle; wherein the voice prompt is used to prompt the driver or passenger in the cabin of the target vehicle to close the window.
[0065] Specifically, before controlling the at least one window of the target vehicle to perform the lifting operation, the presence of a driver or passenger in the cabin of the target vehicle is detected by the passenger detection system, when a driver or passenger is present in the cabin of the target vehicle, the voice prompt system is controlled to issue a voice prompt in the cabin of the target vehicle, for example, a voice prompt "the current cabin humidity is too high, please close the window" is issued. When there is no driver or passenger in the cabin of the target vehicle, the atmosphere lamp sends a closing command to the window control module through the LIN line to control the window of the target vehicle to perform the lifting operation.
[0066] When a driver or passenger is present in the cabin of the target vehicle, it is determined whether a window closing action of the driver or passenger is detected within a preset time, when no window closing action of the driver or passenger is detected within the preset time, the window of the target vehicle is controlled to perform the lifting operation, and a prompt "the window has been automatically closed, please press and hold the unlock key if you want to open it" is added to achieve a suitable environment climate in the cabin.
[0067] In some embodiments, before controlling the at least one window of the target vehicle to perform the lifting operation, first, the gear signal of the target vehicle is acquired by the body controller, if the gear signal of the target vehicle is in a non-parking gear (i.e. non-P gear), it is confirmed that the target vehicle is not in a parking state according to the non-parking gear, and the control of the window of the target vehicle to perform the lifting operation is prohibited to prevent misoperation from affecting driving safety. If the gear signal of the target vehicle is in a parking gear (i.e. P gear), it is confirmed that the target vehicle is in a parking state according to the parking gear, and a signal is fed back to the ambient light through the LIN line. Further, whether the driver or passenger exists in the cabin of the target vehicle is detected by the passenger detection system, when the driver or passenger exists in the cabin of the target vehicle, the voice prompt system is controlled to issue a voice prompt in the cabin of the target vehicle at this time, for example, a voice prompt "the current cabin humidity is too high, please close the window" is issued. When the driver or passenger does not exist in the cabin of the target vehicle, the ambient light sends a closing command to the window control module through the LIN line to control the window of the target vehicle to perform the lifting operation.
[0068] As a specific embodiment, as shown in Figure 8 the window control method of the present application can include the following steps: S801, the target vehicle is in a humid environment such as rain or heavy fog.
[0069] S802, whether the target vehicle is in a parking state is determined. If yes, step S803 is executed; if no, step S806 is executed.
[0070] S803, whether the driver or passenger exists in the cabin of the target vehicle is determined. If yes, step S804 is executed; if no, step S805 is executed.
[0071] S804, the voice prompt system is controlled to issue a voice prompt in the cabin of the target vehicle.
[0072] S805, when the humidity in the cabin continuously accumulates to a certain humidity threshold, the window of the target vehicle is controlled to perform the lifting operation.
[0073] S806, the control of the window of the target vehicle to perform the lifting operation is prohibited.
[0074] In some embodiments, before controlling the at least one window of the target vehicle to perform the lifting operation, the window opening ambient light linkage switch in the large screen of the in-vehicle information entertainment system is opened, further, the linkage switch can be opened in a human-computer interaction manner. Specifically, the linkage switch can be designed in a physical button interaction manner, which can be quickly recognized and used by the user, and the physical button can be more reliable than the touch screen in a complex environment (such as wet hands, wearing gloves). The linkage switch can also be designed in a touch screen interaction manner, the user can operate by directly touching the icon on the screen, for example, refer toFigure 9 For the touch screen human-computer interaction according to some embodiments of the application, an icon of "whether to start the humidity detection function" can be popped up on the screen, and the user can select "yes" or "no" on the screen according to the needs, which can provide clearer and more delicate visual experience, and the user can perform more complex gesture operations such as zooming and rotating, and further, the touch operation usually provides instant feedback such as vibration, sound or visual prompt, which enhances the user experience. The linkage switch can also be designed as a voice interaction mode, which can allow the user to interact with the device through natural language without manual operation, and the user can complete the operation without touching the device. Voice input is usually faster than manual input, which can improve the interaction efficiency.
[0075] For example, five humidity thresholds can be set according to the calibration before the car is shipped, that is, the first humidity threshold (humidity 10-20), the second humidity threshold (humidity 21-30), the third humidity threshold (humidity 31-40), the fourth humidity threshold (humidity 41-50) and the fifth humidity threshold (humidity 51-60), and the relationship between these thresholds is first humidity threshold < second humidity threshold < third humidity threshold < fourth humidity threshold < fifth humidity threshold.
[0076] When the humidity in the target vehicle cabin reaches the first humidity threshold, the humidity in the cabin is small at this time, and the humidity in the cabin needs to be increased, so the two windows of the target vehicle can be controlled to perform the lowering operation; when the humidity in the target vehicle cabin reaches the second humidity threshold, the humidity in the cabin is small at this time, and the humidity in the cabin needs to be increased, so one window of the target vehicle can be controlled to perform the lowering operation; when the humidity in the target vehicle cabin reaches the third humidity threshold, the humidity in the cabin is large at this time, and the humidity in the cabin needs to be reduced, so one window of the target vehicle can be controlled to perform the raising operation; when the humidity in the target vehicle cabin reaches the fourth humidity threshold, the humidity in the cabin is large at this time, and the humidity in the cabin needs to be reduced, so two windows of the target vehicle can be controlled to perform the raising operation; when the humidity in the target vehicle cabin reaches the fifth humidity threshold, the humidity in the cabin is large at this time, and the humidity in the cabin needs to be greatly reduced, so three windows of the target vehicle can be controlled to perform the raising operation.
[0077] When the humidity in the target vehicle cabin is out of standard, the humidity in the cabin is large at this time, and the humidity in the cabin needs to be completely reduced, so all the windows of the target vehicle are controlled to perform the raising operation to prevent the air in the external environment from entering the cabin.
[0078] In some embodiments, when the target vehicle is in a humid environment such as rain or fog, and the windows are open, when the humidity inside the vehicle continuously accumulates and increases to the third humidity threshold, that is, the humidity inside the vehicle has not yet reached the third humidity threshold at first, but only accumulates and increases to the third humidity threshold as the windows continue to be opened, the windows of the target vehicle are controlled to be raised to prevent air from the outside environment from continuing to enter the vehicle.
[0079] In summary, the window control method according to embodiments of the present invention includes: acquiring the transmission spectral intensity detected by a photodetector inside a target vehicle, and confirming whether the transmission spectral intensity is lower than a first preset intensity threshold; in response to the transmission spectral intensity being lower than the first preset intensity threshold, determining that the humidity inside the target vehicle's cabin exceeds the standard, and controlling at least one window of the target vehicle to perform an raising operation. Therefore, this method can detect the humidity inside the target vehicle's cabin, causing the target vehicle's windows to rise or fall, achieving a suitable environmental climate inside the cabin, improving the aesthetics of the cabin, and enhancing the user experience.
