[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Figure 1 Schematic diagram of a vehicle structure provided by an embodiment of the present invention. Figure 1 The vehicle 100 may include a power system 11, a vehicle window glass 12, and a controller 13. The power system 11 is connected to the vehicle window glass 12 and the controller 13, respectively, and can supply power to the vehicle window glass 12 and the controller 13. The controller 13 is also connected to the vehicle window glass 12, and can adjust the light transmittance of the vehicle window glass 12. The vehicle window glass 12 may be the front windshield of the vehicle 100, or may be all the glass of the vehicle 100.

[0041] Optionally, the vehicle 100 may be an electric vehicle or a hybrid vehicle, for example, an electric vehicle. The vehicle window glass 12 may be an electrochromic glass. The light transmittance of the electrochromic glass may vary with a driving parameter. The driving parameter may be a driving current or a driving voltage.

[0042] Optional, reference Figure 2 The power system 11 may include: a power switching unit 111, a first battery 112 and a second battery 113. The power switching unit 111 is connected to the first battery 112, the second battery 113 and the vehicle window glass 12 respectively. The power switching unit 111 may control the first battery 112 or the second battery 113 to supply power to the vehicle window glass 12 under the control of the controller 13.

[0043] In the embodiment of the present invention, the first battery 112 is mainly used to power the vehicle window glass 12, and the second battery 113 can power the vehicle window glass 12 when the remaining power of the first battery 112 is insufficient. In other words, from the perspective of the vehicle window glass 12, the first battery 112 is the main battery, and the second battery 113 is the backup battery.

[0044] Optionally, the charging methods of the first battery 112 and the second battery 113 may be the same or different, for example, they may be different. For example, the first battery 112 may be charged by a solar panel, and the second battery 113 may be charged by a charging gun. Figure 2 The power supply system 11 may further include: a solar panel 114 connected to the first battery 112. The solar panel 114 is used to charge the first battery 112.

[0045] The solar panel 114 has good photoelectric conversion capability and can convert sunlight in the natural environment into electrical energy to charge the first battery 112. As a result, the charging cost of the vehicle 100 can be effectively reduced, and environmental protection and sustainability can be improved. Optionally, the solar panel 114 can be made of single crystal or polycrystalline silicon material, and the solar panel 114 also has waterproof and UV resistance. The first battery 112 can be a high energy density lithium battery with superior charge and discharge performance and a long service life, and can continue to operate safely for a period of time in the absence of sufficient light.

[0046] Optional, such as Figure 2 As shown, the controller 13 may include: a battery management unit 131 and a window controller 132. The battery management unit 131 is connected to the power switching unit 111 and the second battery 113 respectively, and the battery management unit 131 is used to switch the first battery 112 and the second battery 113 through the power switching unit 111 to supply power to the window glass 12. In addition, the battery management unit 131 also has overload protection and short circuit protection functions to ensure that the vehicle 100 can operate safely. The second battery 113 is used to supply power to the battery management unit 131.

[0047] The window controller 132 is connected to the window glass 12 and is used to adjust the light transmittance of the window glass 12. Optionally, the window controller 132 may be an electronic control unit (ECU).

[0048] Optionally, the vehicle 100 further includes: a sensor group 14, which can be connected to the window controller 132, and the sensor group 14 is used to collect data of the environment in which the vehicle 100 is located, and send the data to the window controller 132. The window controller 132 can then adjust the driving parameters of the window glass based on the data to adjust the light transmittance of the window glass 12. The environmental data may include light intensity, ultraviolet intensity, and temperature.

[0049] Optionally, the sensor group 14 may include an ultraviolet sensor, a light sensor, and a temperature sensor. The vehicle 100 may collect the ultraviolet intensity of the environment in which the vehicle 100 is located through the ultraviolet sensor, collect the light intensity of the environment in which the vehicle 100 is located through the light sensor, and collect the temperature of the environment in which the vehicle 100 is located through the temperature sensor.

[0050] Figure 3 is a flow chart of a method for adjusting the light transmittance of a vehicle window glass provided by an embodiment of the present invention, the method is applied to a vehicle, such as Figure 1 Vehicle shown. Reference Figure 3 , the method comprising:

[0051] Step 301: Obtain the light intensity and ultraviolet intensity of the environment in which the vehicle is located.

[0052] In an optional implementation, the vehicle includes a light sensor and an ultraviolet sensor. The vehicle can obtain the light intensity of the vehicle's environment through the light sensor, and can obtain the ultraviolet intensity of the vehicle's environment through the ultraviolet sensor.

[0053] In another optional implementation, the vehicle may establish a communication connection with another vehicle. The light intensity and ultraviolet intensity of the environment in which the vehicle is located may be sent to the vehicle by the other vehicle through the communication connection. The distance between the other vehicle and the vehicle may be less than a preset distance, and the preset distance may be pre-stored in the vehicle.

[0054] Step 302: Adjust the light transmittance of the vehicle window glass based on the light intensity and the ultraviolet intensity.

[0055] In an embodiment of the present invention, the vehicle can adjust the driving parameters of the window glass to adjust the light transmittance of the window glass. The difference between the adjusted light transmittance and the target light transmittance is less than a difference threshold, which can be pre-stored in the vehicle. The target light transmittance is determined based on the light intensity and the ultraviolet intensity.

[0056] In summary, the embodiment of the present invention provides a method for adjusting the light transmittance of a vehicle window glass, wherein the vehicle can obtain the light intensity and ultraviolet intensity of the environment in which the vehicle is located, and automatically adjust the light transmittance of the vehicle window glass based on the light intensity and ultraviolet intensity, thereby adjusting the light entering the vehicle. The difference between the adjusted light transmittance and the target light transmittance is less than the difference threshold, and the target light transmittance is determined based on the light intensity and ultraviolet intensity. Therefore, on the one hand, since the light transmittance of the vehicle window glass can be automatically adjusted without manual adjustment, the efficiency of adjusting the light entering the vehicle is improved, and the intelligence level of the vehicle is improved; on the other hand, since the light transmittance can be automatically adjusted based on the light intensity and ultraviolet intensity, the vehicle can dynamically adjust the light transmittance of the vehicle window glass.

[0057] The embodiment of the present invention takes the controller including a battery management unit and a window controller as an example to exemplarily illustrate the light transmittance adjustment method of the window glass provided by the embodiment of the present invention. The method can be applied to vehicles, such as Figure 1 Vehicle shown. Reference Figure 4 , the method may include:

[0058] Step 401: Get the current status of the vehicle.

[0059] The current state of the vehicle may be a driving state or an ignition-off state. When the vehicle is currently in a driving state, the window controller may execute step 402. When the vehicle is currently in an ignition-off state, the window controller may execute step 404.

[0060] Optionally, the vehicle may further include a speed sensor, which may be used to obtain the current speed of the vehicle and send it to the window controller. When the speed is not 0, the window controller may determine that the current state of the vehicle is a driving state. When the speed is 0, the window controller may determine that the current state of the vehicle is an ignition-off state.

[0061] Step 402: Obtain the light intensity and ultraviolet intensity of the environment in which the vehicle is located.

[0062] When the vehicle is currently in driving state, the window controller can obtain the light intensity and ultraviolet intensity of the environment in which the vehicle is located.

[0063] For example, the window controller can control the light sensor to collect and upload the light intensity of the vehicle's environment, and control the ultraviolet sensor to collect and upload the ultraviolet intensity of the environment.

[0064] Step 403: Adjust the light transmittance of the vehicle window glass based on the light intensity and the ultraviolet intensity.

[0065] In an embodiment of the present invention, the window controller can determine the target light transmittance based on the light intensity and the ultraviolet intensity. If the window controller determines that the target light transmittance is greater than the current light transmittance of the window glass, it can be determined that the current light transmittance of the window glass is too low, and then the light transmittance of the window glass can be increased. If the window controller determines that the target light transmittance is less than the current light transmittance of the window glass, it can be determined that the current light transmittance of the window glass is too high, and then the light transmittance of the window glass can be lowered. If the window controller determines that the target light transmittance is equal to the current light transmittance of the window glass, it can be determined that the current light transmittance of the window glass is moderate, and then it can be determined that there is no need to adjust the light transmittance of the window glass.

[0066] The target light transmittance may be determined based on the current light intensity and the current ultraviolet intensity. For example, the window controller may store a correspondence between light intensity, ultraviolet intensity, and light transmittance. The window controller may determine the light transmittance corresponding to the current light intensity and the current ultraviolet intensity in the correspondence as the target light transmittance.

[0067] In the embodiment of the present invention, the current light transmittance of the vehicle window glass can be recorded in the vehicle window controller. Specifically, each time the light transmittance of the vehicle window glass is adjusted, the vehicle window controller can determine the adjusted light transmittance of the vehicle window glass as the current light transmittance of the vehicle window glass and record the current light transmittance.

[0068] It is understandable that when the vehicle is in motion, the current light transmittance of the window glass must be greater than the minimum light transmittance required for safe driving by the driver, so as to ensure that the driver can observe the surrounding driving environment, thereby ensuring a good field of vision for the driver. Therefore, when the vehicle is currently in motion and the current light transmittance of the window glass needs to be lowered, the light transmittance threshold (i.e., the minimum light transmittance mentioned above) needs to be considered to ensure safe driving of the vehicle.

[0069] Specifically, if the window controller determines that the target light transmittance is less than the current light transmittance of the window glass, that is, the light transmittance of the window glass needs to be lowered, it can be detected whether the current light transmittance of the window glass is greater than the light transmittance threshold. If the window controller determines that the light transmittance of the window glass is greater than the light transmittance threshold, the light transmittance of the window glass can be lowered. If the window controller determines that the light transmittance of the window glass is less than or equal to the light transmittance threshold, it can be determined that the light transmittance of the window glass does not need to be adjusted.

[0070] In an embodiment of the present invention, the window controller can adjust the driving parameters of the window glass to adjust the light transmittance of the window glass. Optionally, the window controller can use a PID algorithm to adjust the light transmittance of the window glass. In this way, it can be ensured that the light transmittance of the window glass can change smoothly, thereby further ensuring that the driving safety of the vehicle is high.

[0071] Taking the driving voltage of the window glass as an example, the window controller using the PID algorithm to adjust the light transmittance of the window glass is described as follows:

[0072] After the window controller determines the target light transmittance based on the light intensity and ultraviolet intensity of the vehicle's environment, it can determine the difference between the current light transmittance of the window glass and the target light transmittance. Then, the window controller can process the difference through the PID algorithm to obtain the light transmittance adjustment value of the window glass, and then determine the driving voltage adjustment value based on the light transmittance adjustment value. Afterwards, the window controller can adjust the driving voltage of the window glass based on the driving voltage adjustment value of the window glass to adjust the light transmittance of the window glass.

[0073] Step 404: Obtain the temperature of the environment in which the vehicle is located.

[0074] When the vehicle is currently in an ignition-off state, the window controller can obtain the temperature of the vehicle's environment.

[0075] Step 405: Detect whether the temperature of the environment in which the vehicle is located is greater than a temperature threshold.

[0076] If the temperature of the vehicle's environment is greater than the temperature threshold, the window controller may execute step 406. If the temperature of the vehicle's environment is less than or equal to the temperature threshold, the process may end. The temperature threshold may be pre-stored in the window controller.

[0077] Optionally, if the temperature of the environment in which the vehicle is located is less than or equal to the temperature threshold, the window controller may first increase the light transmittance of the window glass (eg, to the highest value) and then terminate the process.

[0078] It is understandable that when the vehicle is currently in the off state, even if the light passing through the window glass will irritate the driver's eyes, no safety accident will occur. Therefore, when the vehicle is currently in the off state, the comfort of the driver and passengers is mainly considered to adjust the light transmittance of the window glass. Because the temperature of the vehicle's environment is low, it is usually necessary to allow as much light as possible to enter the vehicle, and because the first battery charged by solar energy is preferred to power the window glass, and the light is not strong when the temperature is low, frequent adjustments to the light transmittance will consume too much electricity, so the light transmittance of the window glass is generally not adjusted at this time. In this way, on the one hand, as much light as possible can be allowed to enter the car to improve the comfort of the driver and passengers, and on the other hand, the power consumption of the first battery can be reduced. When the temperature of the environment is high, the light may cause harm to the driver and passengers, so the light transmittance of the window glass needs to be adjusted at this time.

[0079] Based on this, when the vehicle is currently in the off state, the temperature of the vehicle's environment can be obtained, and based on the relationship between the temperature and the temperature threshold, it is decided whether to adjust the light transmittance of the window glass.

[0080] Step 406: Detect whether the light intensity of the environment in which the vehicle is located is greater than the first intensity threshold, and whether the ultraviolet intensity is greater than the second intensity threshold.

[0081] When the temperature of the vehicle's environment is greater than the temperature threshold, the window controller can detect whether the light intensity of the vehicle's environment is greater than the first intensity threshold, and whether the ultraviolet intensity of the vehicle's environment is greater than the second intensity threshold. When the light intensity is greater than the first intensity threshold, and / or the ultraviolet intensity is greater than the second intensity threshold, the window controller can determine that the light may cause harm to the driver and passengers (such as sunburn), and then step 403 can be executed. When the light intensity is less than or equal to the first intensity threshold, and the ultraviolet intensity is less than or equal to the second intensity threshold, the window controller can determine that the light will not cause harm to the driver and passengers, and thus it can be determined that there is no need to adjust the current light transmittance of the window glass, and then the process can be terminated. The first intensity threshold and the second intensity threshold can be pre-stored in the window controller.

[0082] According to the above description, in the embodiment of the present invention, when the window controller adjusts the window glass, it not only takes into account the current light intensity, but also takes into account the current ultraviolet intensity. This improves the adjustment accuracy of the window glass on the one hand, and on the other hand, reduces the discomfort caused by excessive light to the vision of the driver and passengers, while reducing the damage of ultraviolet rays to the eyes of the driver and passengers, providing more comprehensive protection for the driver and passengers.

[0083] Step 407: Determine whether the remaining power of the first battery is greater than a power threshold.

[0084] In the embodiment of the present invention, both the first battery and the second battery can power the vehicle window glass, and the first battery is preferentially used to power the vehicle window glass. Based on this, the battery management unit can determine whether the remaining power of the first battery is greater than the power threshold. If the remaining power of the first battery is greater than the power threshold, the battery management unit can execute step 408. If the remaining power of the first battery is less than or equal to the power threshold, the battery management unit can execute step 409.

[0085] Step 408: Control the first battery to supply power to the vehicle window glass.

[0086] When the remaining power of the first battery is greater than the power threshold, the battery management unit can determine that the remaining power of the first battery is sufficient, and can control the first battery to supply power to the vehicle window glass.

[0087] It is understandable that if the second battery is currently supplying power to the vehicle window glass, the battery management unit may send a first switching signal to the power switching unit when determining that the remaining power of the first battery is greater than the power threshold. In response to the first switching signal, the power switching unit may disconnect the connection path between the second battery and the vehicle window glass, and connect the connection path between the first battery and the vehicle window glass, so as to switch the battery supplying power to the vehicle glass from the second battery to the first battery. In this way, the first battery can be controlled to supply power to the vehicle window glass.

[0088] Step 409: Control the second battery to supply power to the vehicle window glass.

[0089] When the remaining power of the first battery is less than or equal to the power threshold, the battery management unit can control the second battery to supply power to the vehicle window glass.

[0090] It is understandable that if the first battery is currently supplying power to the vehicle window glass, the battery management unit may send a second switching signal to the power switching unit when determining that the remaining power of the first battery is less than or equal to the power threshold. In response to the second switching signal, the power switching unit may disconnect the connection path between the first battery and the vehicle window glass, and connect the connection path between the second battery and the vehicle window glass, so as to switch the battery supplying power to the vehicle glass from the first battery to the second battery. In this way, the second battery can be controlled to supply power to the vehicle window glass.

[0091] According to the description of steps 407 to 409, when the remaining power of the first battery is sufficient, the power management unit preferentially controls the first battery to supply power to the vehicle window glass. When the remaining power of the first battery is insufficient, the power management unit can control the second battery to supply power to the vehicle window glass. In this way, the power supply reliability of the vehicle window glass can be ensured, and the problem of being unable to adjust the light transmittance of the vehicle window glass due to power interruption can be avoided.

[0092] The above embodiment is an exemplary description of the case where the power management unit automatically switches to the battery that powers the vehicle window glass based on the remaining power of the first battery. It is understandable that the central control screen of the vehicle can display the power switching control and the identification of the battery currently powering the vehicle window glass. If the driver or passenger needs to switch to the battery that powers the vehicle window glass, the power switching control can be touched. The vehicle's power management unit can switch to the battery that powers the vehicle window glass in response to the touch operation on the power switching control. For example, if the battery currently powering the vehicle glass is the first battery, the power management unit can control the second battery to power the vehicle window glass in response to the touch operation on the power switching control.

[0093] In the embodiment of the present invention, the vehicle can switch the battery, that is, the first battery or the second battery is used for power supply, thereby reducing the vehicle's dependence on the first battery (or the second battery) and extending the service life of the first battery and the second battery.

[0094] It is understandable that the order of the steps of the method for adjusting the light transmittance of the vehicle window glass provided by the embodiment of the present invention can be appropriately adjusted, and the steps can be increased or decreased accordingly according to the situation. For example, steps 406 to 409 can be performed before step 401. Any technician familiar with the technical field can easily think of a method of variation within the technical scope disclosed in this application, which should be included in the protection scope of this application, so it will not be repeated.

[0095] In summary, the embodiment of the present invention provides a method for adjusting the light transmittance of a vehicle window glass, wherein the vehicle can obtain the light intensity and ultraviolet intensity of the environment in which the vehicle is located, and automatically adjust the light transmittance of the vehicle window glass based on the light intensity and ultraviolet intensity, thereby adjusting the light entering the vehicle. The difference between the adjusted light transmittance and the target light transmittance is less than the difference threshold, and the target light transmittance is determined based on the light intensity and ultraviolet intensity. Therefore, on the one hand, since the light transmittance of the vehicle window glass can be automatically adjusted without manual adjustment, the efficiency of adjusting the light entering the vehicle is improved, and the intelligence level of the vehicle is improved; on the other hand, since the light transmittance can be automatically adjusted based on the light intensity and ultraviolet intensity, the vehicle can dynamically adjust the light transmittance of the vehicle window glass.

[0109] Optionally, the vehicle further comprises: a first battery and a second battery, and the window glass is connected to the first battery and the second battery respectively; Figure 6 The device 60 may further include a control module 603, which may be used to:

[0110] When the remaining power of the first battery is greater than the power threshold, controlling the first battery to supply power to the vehicle window glass;

[0112] In summary, the embodiment of the present invention provides a light transmittance adjustment device for vehicle window glass, and the vehicle can obtain the light intensity and ultraviolet intensity of the environment in which the vehicle is located, and automatically adjust the light transmittance of the vehicle window glass based on the light intensity and ultraviolet intensity, thereby realizing the adjustment of the light entering the vehicle. The difference between the adjusted light transmittance and the target light transmittance is less than the difference threshold, and the target light transmittance is determined based on the light intensity and ultraviolet intensity. Therefore, on the one hand, since the light transmittance of the vehicle window glass can be automatically adjusted without manual adjustment, the efficiency of adjusting the light entering the vehicle is improved, and the intelligence level of the vehicle is improved; on the other hand, since it can be automatically adjusted based on the light intensity and ultraviolet intensity, the vehicle can dynamically adjust the light transmittance of the vehicle window glass.
