Description

Technical Field

[0001] The present application relates to the technical field of glass gear adjustment, and particularly relates to a gear control method, device, controller and vehicle for a dimming glass. Background Art

[0002] A dimming glass refers to a glass with a film structure added between traditional double-layer glasses to achieve adjustable light transmittance. Dimming glasses are used in many fields. However, currently, dimming glasses often have the problem of short service life during use. For example, due to significant heat insulation and privacy effects, the technology has gradually matured, and at the same time, the cost has become lower and lower. Dimming glasses have begun to be used as sunroof glasses in some vehicles. However, currently, the dimming glasses used as sunroof glasses in vehicles have a short service life and do not meet the service life requirements of vehicle regulations, which affects the user experience. Summary of the Invention

[0003] Embodiments of the present application provide a gear control method, device, controller and vehicle for a dimming glass, which can extend the service life of the dimming glass and make the dimming glass approach or meet the service life requirements of vehicle regulations when applied to a vehicle.

[0004] In a first aspect, the present application provides a gear control method for a dimming glass, including: detecting a trigger condition for adjusting the gear of a target dimming glass from a first gear to a second gear; obtaining a first temperature value of the target dimming glass; the first temperature value is used to represent the real-time temperature measurement value of the target dimming glass; obtaining a first temperature compensation value, and performing temperature compensation on the first temperature value according to the first temperature compensation value to obtain a second temperature value; the first temperature compensation value is used to compensate for the difference between the first temperature value and the actual temperature value of the target dimming glass; when it is determined according to the second temperature value that the target dimming glass supports working in the second gear at the second temperature value, adjusting the gear of the target dimming glass from the first gear to the second gear. In this method, temperature compensation is performed on the first temperature value to make the second temperature value closer to the actual temperature value of the target dimming glass. Then, when it is determined based on the second temperature value that the target dimming glass supports the second gear, the gear of the target dimming glass is adjusted to the second gear, so that the target dimming glass always works in a suitable gear, reducing inappropriate gear adjustments under high temperature and other conditions, thereby extending the service life of the target dimming glass. Furthermore, when the target dimming glass is applied to a vehicle, the service life of the target dimming glass can approach or meet the service life requirements of vehicle regulations.

[0005] In some possible implementation manners, obtaining the first temperature compensation value includes: determining the first temperature compensation value according to a first target parameter; the first target parameter includes a parameter that can affect the temperature of the target dimming glass; the first target parameter includes at least one of the following: the illumination level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located. In this method, the first temperature compensation value is determined by the first target parameter that can affect the temperature of the target dimming glass, so that the second temperature value can be made as close as possible to the actual temperature value of the target dimming glass, thereby improving the gear adjustment accuracy of the target dimming glass and prolonging the service life of the target dimming glass.

[0006] In some possible implementation manners, determining the first temperature compensation value according to the first target parameter includes: determining the first temperature compensation value according to the first target parameter and the first temperature value. In this method, the first temperature compensation value is determined by combining the first temperature value on the basis of the first target parameter, thereby improving the accuracy of the first temperature compensation value.

[0007] In some possible implementation manners, the first target parameter includes: the driving speed of the vehicle where the target dimming glass is located; determining the first temperature compensation value according to the first target parameter and the first temperature value includes: determining the first speed interval where the driving speed is located; determining the first temperature interval where the first temperature value is located; searching in the preset first information for the temperature compensation value corresponding to the combination of the first speed interval and the first temperature interval, and using it as the first temperature compensation value; the preset first information records the temperature compensation values corresponding to the combinations of different speed intervals and first temperature intervals. In this method, the first temperature compensation value is determined by the driving speed of the vehicle and the first temperature value, thereby improving the accuracy of the first temperature compensation value.

[0008] In some possible implementation manners, in the first information, for the combinations formed by the same temperature interval and different speed intervals, the temperature compensation value corresponding to the combination where the speed interval with a relatively larger speed is located is relatively smaller; for the combinations formed by the same speed interval and different temperature intervals, the temperature compensation value corresponding to the combination where the temperature interval with a relatively smaller temperature is located is relatively smaller.

[0009] In some possible implementation manners, obtaining the first temperature compensation value includes: obtaining a preset third temperature value as the first temperature compensation value; or, obtaining a fourth temperature value corresponding to the target dimming glass as the first temperature compensation value. In this method, the first temperature compensation value can be directly searched, thereby improving the processing speed of the gear control method and the gear adjustment speed in the embodiments of the present application.

[0010] In some possible implementation manners, before obtaining the first temperature compensation value and performing temperature compensation on the first temperature value according to the first temperature compensation value, the method further includes: obtaining a second target parameter, where the second target parameter includes a parameter that can affect the temperature of the target dimming glass; determining, according to the second target parameter, to perform temperature compensation on the first temperature value. When the method determines to perform temperature compensation on the first temperature value according to the second target parameter first, it then performs temperature compensation on the first temperature value according to the first temperature compensation value, thereby filtering out some scenarios that do not require temperature compensation and improving the processing speed and gear adjustment speed of the gear control method in the embodiments of the present application.

[0011] In some possible implementation manners, the second target parameter includes at least one of the following: the light intensity level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located.

[0012] In some possible implementation manners, the second target parameter includes the light intensity level received by the target dimming glass and the ambient temperature of the environment where the target dimming glass is located; determining, according to the second target parameter, to perform temperature compensation on the first temperature value includes: determining a second temperature range in which the ambient temperature is located; finding, from preset second information, indication information corresponding to the combination of the light intensity level and the second temperature range; the indication information is used to indicate whether to perform temperature compensation on the first temperature value; the second information records indication information corresponding to combinations of different light intensity levels and second temperature ranges; determining that the indication information is first indication information, and the first indication information is used to indicate performing temperature compensation on the first temperature value. In this method, it is determined whether to perform temperature compensation on the first temperature according to the light intensity level and the ambient temperature, thereby improving the determination accuracy.

[0013] In some possible implementation manners, the trigger condition for detecting that the gear of the target dimming glass is adjusted from the first gear to the second gear includes: receiving a user operation for adjusting the gear of the target dimming glass from the first gear to the second gear; or, detecting an automatic adjustment decision for adjusting the gear of the target dimming glass from the first gear to the second gear in the automatic adjustment mode of the target dimming glass; or, when the vehicle where the target dimming glass is located is powered on and the time interval between the vehicle power-on time and the previous vehicle power-off time is not greater than a preset time threshold, obtaining historical information that the target dimming glass was in the second gear when the vehicle was powered off last time; or, when the vehicle where the target dimming glass is located is powered on and the time interval between the vehicle power-on time and the previous vehicle power-off time is greater than the preset time threshold, determining that the target gear of the target dimming glass is the second gear. Therefore, the embodiments of the present application can control the gear of the target dimming glass in multiple scenarios, so that the target dimming glass works in a suitable gear, reduce inappropriate gear adjustments under conditions such as high temperature, thereby extending the service life of the target dimming glass. Furthermore, when the target dimming glass is applied to a vehicle, the service life of the target dimming glass can be close to or meet the service life requirements of vehicle regulations.

[0014] In some possible implementation manners, it further includes: when it is determined according to the second temperature value that the target dimming glass does not support working in the second gear at the second temperature value, keeping the gear of the target dimming glass as the first gear and prompting that the gear adjustment fails. Thus, it is ensured that when the target dimming glass does not support the second gear, it works in the first gear that it can support, and the service life of the target dimming glass is extended.

[0015] In some possible implementation manners, the determining that the target dimming glass supports working in the second gear at the second temperature value according to the second temperature value includes: finding the first light transmittance corresponding to the combination of the second temperature value and the second gear from preset third information, and determining that the target dimming glass can work in the second gear; the third information is used to record the light transmittance corresponding to the gears that the target dimming glass can support at different temperatures. In this method, it is possible to determine whether the target dimming glass supports working in the second gear at the second temperature value by looking up a table, which improves the processing speed of the gear control method and the gear adjustment speed of the embodiments of the present application.

[0016] In some possible implementation manners, it further includes: adjusting the light transmittance of the target dimming glass to the first light transmittance. Thus, the target dimming glass can not only work in a suitable gear but also work at a suitable light transmittance, thereby extending the service life of the target dimming glass.

[0017] In some possible implementation manners, finding the first light transmittance corresponding to the combination of the second temperature value and the second gear from the preset third information includes: determining the third temperature range where the second temperature value is located; finding the first light transmittance corresponding to the combination of the third temperature range and the second gear from the preset third information; the third information is specifically used to record the light transmittance corresponding to the gears that the target dimming glass can support under different third temperature ranges.

[0018] In some possible implementation manners, it further includes: obtaining a fifth temperature value of the target dimming glass; the fifth temperature value is used to represent the real-time temperature measurement value of the target dimming glass; obtaining a second temperature compensation value, and performing temperature compensation on the fifth temperature value according to the second temperature compensation value to obtain a sixth temperature value; determining the third temperature range where the sixth temperature value is located; when the third temperature range where the sixth temperature value is located is different from the third temperature range where the second temperature value is located, and the light transmittance corresponding to the combination of the third temperature range where the sixth temperature value is located and the second gear cannot be found from the preset third information, adjusting the gear of the target dimming glass from the second gear to a third gear, and the third gear is the gear that the target dimming glass can support at the sixth temperature value. In this method, when the target dimming glass does not support working in the second gear, the target dimming glass is adjusted to the third gear that can be supported, so that the target dimming glass works in a suitable gear, reducing inappropriate gear adjustment under high temperature and other conditions, thereby prolonging the service life of the target dimming glass.

[0019] In some possible implementation manners, it further includes: when the third temperature range where the sixth temperature value is located is different from the third temperature range where the second temperature value is located, and the second light transmittance corresponding to the combination of the third temperature range where the sixth temperature value is located and the second gear is found from the preset third information, adjusting the light transmittance of the target dimming glass to the second light transmittance. In this method, when the real-time temperature of the target dimming glass changes, the light transmittance of the target dimming glass is dynamically adjusted, so that the target dimming glass works in a suitable gear and light transmittance, thereby prolonging the service life of the target dimming glass.

[0020] In some possible implementation manners, the target dimming glass is specifically the left window and / or the right window of the vehicle where the target dimming glass is located.

[0021] In some possible implementation manners, obtaining the first temperature value of the target dimming glass includes: obtaining the first temperature value of the target dimming glass from a temperature sensor, and the temperature sensor is located on the triangular glass of the left rear door or the right rear door of the vehicle.

[0043] The terms used in the detailed implementation manners of the present application are only for explaining the specific embodiments of the present application, rather than aiming to limit the present application.

[0044] Figure 1 A schematic structural diagram of a vehicle provided by an embodiment of the present application. The vehicle 100 may include various subsystems, for example: a traveling system 110, a sensor system 120, a control system 130, one or more peripheral devices 140, and a computer system 150. Optionally, the vehicle 100 may include more or fewer subsystems, and each subsystem may include multiple elements. In addition, each subsystem and element of the vehicle 100 may be interconnected by wire or wirelessly.

[0045] The propulsion system 110 may include components that provide powered movement for the vehicle 100. In one embodiment, the propulsion system 110 may include an engine 111, a transmission 112, an energy source 113, and wheels / tires 114. The engine 111 may be an internal combustion engine, an electric motor, an air compression engine, or a combination of other types of engines, such as a hybrid engine composed of a gasoline engine and an electric motor, or a hybrid engine composed of an internal combustion engine and an air compression engine. The engine 111 converts the energy source 113 into mechanical energy.

[0046] Examples of the energy source 113 include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other power sources. The energy source 113 may also provide energy for other systems of the vehicle 100.

[0047] The transmission 112 may transmit mechanical power from the engine 111 to the wheels 114. The transmission 112 may include a gearbox, a differential, and a drive shaft. In one embodiment, the transmission 112 may also include other devices, such as a clutch. Among them, the drive shaft may include one or more shafts that can be coupled to one or more wheels 114.

[0048] The sensor system 120 may include several sensors that sense information about the surrounding environment of the vehicle 100 or information inside the vehicle 100. For example, the sensor system 120 may include: a window temperature sensor 121, a sunlight and rain sensor 122, a body environment temperature sensor 123, and a positioning system 124, etc. [[ID=!0]]

[0049] The window temperature sensor 121 is used to sense the temperature of the window. In some embodiments, the window temperature sensor 121 may include an NTC probe, and the NTC probe may be disposed in the black edge of the window. In some embodiments, one or more NTC probes may be provided for each window. When multiple NTC probes are provided for one window, the above NTC probes may be located at different positions of the window to sense the temperatures at different positions of the window. In other embodiments, one NTC probe may be provided for multiple windows, and the NTC probe may be disposed on one of the multiple windows to sense the real-time temperature of this window as the real-time temperature of the multiple windows.

[0050] The sunlight and rain sensor 122 can be used to sense the light intensity received by the vehicle and the rainfall in the environment where the vehicle is located.

[0051] The body environment temperature sensor 123 can be used to sense the ambient temperature outside the vehicle.

[0052] The positioning system 124 can be used to estimate the geographical location of the vehicle 100. The positioning system can be, for example, a global positioning system (GPS) system, or a Beidou system or other positioning systems.

[0053] The control system 130 performs operations to control the vehicle 100 and its components. The control system 130 can include various elements, such as a window control system 131, a steering system 132, a throttle 133, a braking unit 134, etc.

[0054] The window control system 131 can be operated to adjust the vehicle's windows, including panoramic glass, side windows, etc.

[0055] The steering system 132 can be operated to adjust the forward direction of the vehicle 100. For example: in one embodiment, it can be a steering wheel system.

[0056] The throttle 133 is used to control the operating speed of the engine 111 and thus control the speed of the vehicle 100.

[0057] The braking unit 134 is used to control the deceleration of the vehicle 100. The braking unit 134 can use friction to slow down the wheels 114.

[0058] In other embodiments, the braking unit 134 can convert the kinetic energy of the wheels 114 into electric current. The braking unit 134 can also take other forms to slow down the rotational speed of the wheels 114 so as to control the speed of the vehicle 100.

[0059] Of course, in one instance, the control system 130 can additionally or alternatively include components other than those shown and described. Or some of the above - shown components can also be reduced.

[0060] The vehicle 100 interacts with external sensors, other vehicles, other computer systems or users through the peripheral device 140. The peripheral device 140 can include a wireless communication system 141, an on - vehicle computer 142, a microphone 143 and / or a speaker 144.

[0061] In some embodiments, the on - vehicle computer 142 can provide information to the user of the vehicle 100. The user can operate through the touch screen of the on - vehicle computer 142, interact with the on - vehicle computer 142, and thus achieve interaction with the vehicle 100. In other cases, the peripheral device 140 can provide means for the vehicle 100 to communicate with other devices located inside the vehicle. For example, the microphone 143 can receive audio (such as voice commands or other audio inputs) from the user of the vehicle 100. Similarly, the speaker 144 can output audio to the user of the vehicle 100.

[0062] The wireless communication system 141 can communicate wirelessly with one or more devices directly or via a communication network. For example, the wireless communication system 141 can use 3G cellular communication, such as Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM) / GPRS, or fourth generation (4G) communication, such as Long-Term Evolution (LTE). Or fifth generation (5G) communication. The wireless communication system 141 can communicate with a wireless local area network (WLAN) using WiFi. In some embodiments, the wireless communication system 141 can communicate directly with devices using an infrared link, Bluetooth, or ZigBee. For other wireless protocols, such as various vehicle communication systems, for example, the wireless communication system 141 can include one or more dedicated short range communications (DSRC) devices, which can include public and / or private data communications between vehicles and / or roadside stations.

[0063] Some or all of the functions of the vehicle 100 are controlled by the computer system 150. The computer system 150 can include at least one processor 151 that executes instructions 153 stored in a non-transitory computer-readable medium such as a data memory 152. The computer system 150 can also be multiple computing devices that control individual components or subsystems of the vehicle 100 in a distributed manner.

[0064] The processor 151 can be any conventional processor, such as a commercially available central processing unit (CPU). Alternatively, the processor can be a special-purpose device such as an application-specific integrated circuit (ASIC) or other hardware-based processor. Although Figure 1 the functional diagram shows the processor and the memory, those of ordinary skill in the art should understand that the processor or the memory can actually include multiple processors or memories that are not stored within the same physical housing. For example, the memory can be a hard disk drive or other storage medium. Therefore, the reference to a processor will be understood to include a reference to a collection of processors or memories that may not operate in parallel. Different from using a single processor to perform the steps described herein, some components such as the steering component and the deceleration component can each have its own processor that only performs calculations related to component-specific functions.

[0065] In some embodiments, the memory 152 may include instructions 153 (e.g., program logic) that may be executed by the processor 151 to perform various functions of the vehicle 100, including those described above. The memory 152 may also include additional instructions, including instructions to send data to, receive data from, interact with, and / or control one or more of the propulsion system 110, the sensor system 120, the control system 130, and the peripheral devices 140.

[0066] In addition to the instructions 153, the memory 152 may also store data, such as road maps, route information, the location, direction, speed of the vehicle, and other such vehicle data, as well as other information. Such information may be used by the vehicle 100 and the computer system 150 during operation of the vehicle 100 in autonomous, semi-autonomous, and / or manual modes.

[0067] The computer system 150 may control the functions of the vehicle 100 based on data received from the various subsystems (e.g., the propulsion system 110, the sensor system 120, and the control system 130) and user input received. In some embodiments, the computer system 150 may be operable to provide control over many aspects of the vehicle 100 and its subsystems.

[0068] Optionally, one or more of the above components may be installed or associated separately from the vehicle 100. For example, the memory 152 may exist partially or completely separately from the vehicle 100. The above components may be communicatively coupled together in a wired and / or wireless manner.

[0069] Optionally, the above components are just an example. In actual applications, the components in each of the above modules may be added or deleted according to actual needs. Figure 1 It should not be construed as a limitation to the embodiments of the present application.

[0070] The above vehicle 100 may be a sedan, a truck, a motorcycle, a bus, a ship, an airplane, a helicopter, a lawn mower, a recreational vehicle, a playground vehicle, a construction vehicle, a tram, a golf cart, a train, or a trolley, etc., and the embodiments of the present application do not make special limitations.

[0071] Hereinafter, the method, device, controller, and vehicle for controlling the gear of the dimming glass in the embodiments of the present application will be exemplarily described in conjunction with the above vehicle structure. The gear in the embodiments of the present application refers to the gear used to adjust the light transmittance of the dimming glass.

[0072] A dimming glass refers to a glass with a film structure installed between traditional double - layer glasses to achieve adjustable light transmittance. Currently, the main technical solutions for dimming glass include polymer dispersed liquid crystal (PDLC), suspended particle device (SPD), dye liquid crystal (DLC), electrochromic (EC), etc. The main parameter of dimming glass is the light transmittance. The light transmittance of dimming glass refers to the ratio of the amount of light that can pass through to the amount of incident light when light passes through the dimming glass. The higher the light transmittance, the more transparent the dimming glass; conversely, the less transparent the dimming glass. Taking the electrochromic technical solution as an example, the principle of electrochromism is that under the action of an external electric field, the electrochromic material undergoes stable and reversible chemical changes, thereby changing the transmittance of the material, which is manifested as reversible changes in color and transparency in appearance.

[0073] Due to its significant heat insulation and privacy effects, the technology is gradually maturing, and at the same time, the cost is getting lower and lower. Dimming glass is applied in many fields. However, dimming glass currently has the problem of a relatively short service life.

[0074] For example, due to the characteristics of high magnification and neutral black in both bright and dark states, EC dimming glass is currently starting to be used as a sunroof glass in some vehicles. During the use of the vehicle, the vehicle or the user can adjust the gear of the sunroof glass to adjust the light transmittance of the sunroof glass. However, because EC dimming glass is sensitive to temperature, during the dimming process of EC dimming glass in a high - temperature environment, the number of uncontrollable side reactions increases. Especially when the sun shines strongly during the day in summer, the temperature of the sunroof glass is very high. Adjusting the EC dimming glass used as the sunroof glass at a large magnification during use will have a greater impact on the service life of the EC dimming glass, resulting in a serious attenuation of the service life of the EC dimming glass and not meeting the service life requirements of vehicle regulations, which affects the user experience. Other dimming glasses that are sensitive to temperature also have similar problems during use, resulting in a relatively short service life of the dimming glass and affecting the user's use experience.

[0075] Therefore, the embodiments of this application provide a method for controlling the gear of dimming glass, which can extend the service life of dimming glass, so that when dimming glass, such as EC dimming glass, is applied to vehicles, its service life is close to or meets the service life requirements of vehicle regulations.

[0076] The dimming glass in the embodiments of this application is not limited to being used as a sunroof glass, and can also be used as side windows, windshield glass, etc. of vehicles, or as glass for other purposes on vehicles, to achieve the above - mentioned control of the gear of dimming glass, thereby expanding the application range of dimming glass in vehicles.

[0077] The window configurations of different vehicles may vary. For example, Figure 2 As shown, it is a schematic diagram of the window configuration of a vehicle, which is equipped with 2 windshield glasses: a front windshield and a rear windshield, 2 panoramic glass: panoramic glass 1 and panoramic glass 2, 5 left-side windows: a fixed glass of the left front door, a lifting glass of the left front door, a fixed glass of the left rear door, a lifting glass of the left rear door, and a triangular glass of the left rear door, and 5 right-side windows ( Figure 2 not shown in the figure): a fixed glass of the right front door, a lifting glass of the right front door, a fixed glass of the right rear door, a lifting glass of the right rear door, and a triangular glass of the right rear door.

[0078] It should be noted that here, left and right can be considered as follows: when a passenger is sitting normally in vehicle 100 and facing the front of the vehicle, the left side of the passenger is the left side of the vehicle, and the right side of the passenger is the right side of the vehicle. Correspondingly, the windows located on the left side of the vehicle are collectively referred to as left-side windows, and the windows located on the right side of the vehicle are collectively referred to as right-side windows.

[0079] It can be understood that Figure 2 This is only an example of the window configuration of the vehicle, for the convenience of subsequent examples, and is not used to limit the window configuration of the vehicle.

[0080] In some embodiments, when the dimming glass is used as a window of the vehicle, a corresponding window controller can be set in the vehicle to execute the gear control method of the dimming glass in the embodiments of the present application through the window controller to achieve the gear control of the window.

[0081] The following takes the Figure 2 vehicle shown as an example for exemplary illustration.

[0082] Assume that the dimming glass is used as the left-side window and the right-side window. As shown in Figure 3 the figure, the vehicle may include: a left-side window controller set for the left-side window, and a right-side window controller set for the right-side window. In addition, the vehicle may also include processors such as a cockpit domain controller and a body domain controller.

[0083] The cockpit domain controller can be used to manage and monitor various systems of the vehicle, provide intelligent control and multi-functional integration, and ensure the safety and comfort of the vehicle.

[0084] The body domain controller can be used to manage and control various electronic systems and functions of the vehicle, including operating windows, rearview mirrors, etc.

[0085] The left-side window controller is used to execute the gear control method of the dimming glass in the embodiments of the present application to achieve the gear control of the left-side window.

[0086] The right-side window controller is used to execute the gear control method of the dimming glass in the embodiments of the present application to achieve the gear control of the right-side window.

[0087] The cockpit domain controller and the body domain controller can be connected via in-vehicle Ethernet, and the body domain controller can be connected to the left window controller and the right window controller respectively via the CAN bus.

[0088] See Figure 3 , each piece of glass on the left window can be connected to the left window controller respectively, and each piece of glass on the right window can be connected to the right window controller respectively. The specific connection method is not limited in the embodiments of the present application, as long as the left window controller can achieve gear control of each piece of glass on the left window and the right window controller can achieve gear control of each piece of glass on the right window.

[0089] It can be understood that Figure 3 taking all the glass of the left window and the right window being realized by dimming glass as an example, in other embodiments, part of the glass of the left window and the right window can also be realized by dimming glass, which is not limited in the embodiments of the present application.

[0090] It can be understood that Figure 3 only as an example, if the dimming glass is used as a panoramic glass or a windshield, etc., a corresponding panoramic glass controller or windshield controller can also be set in the vehicle.

[0091] It can be understood that Figure 3 taking the example of setting corresponding controllers for different types of windows (windshield, side window or panoramic glass) respectively, in other embodiments, the functions of the above-mentioned controllers can also be combined or further split. For example, the left window controller and the right window controller are realized by one controller, or further corresponding controllers are set for different side window glasses, etc.

[0092] In some embodiments, see Figure 3 as shown, the above-mentioned left window controller and right window controller can be controllers powered by low voltage, and a power supply can be set in the vehicle to supply power to the above-mentioned left window controller and right window controller. The above-mentioned power supply can be, for example, a 12V battery.

[0093] In some embodiments, one or more temperature sensors (such as NTC probes) can be set for the left window and the right window in the vehicle respectively to measure the real-time temperature of the left window and the right window. In the embodiments of the present application, the temperature sensor set for the left window is called the left temperature sensor, and the temperature sensor set for the right window is called the right temperature sensor. See Figure 3 as shown, the left temperature sensor can be connected to the left window controller, and the right temperature sensor can be connected to the right window controller to send the measured real-time temperature to the corresponding controller.

[0094] The following provides an exemplary illustration of the possible interface implementation of the gear control method for the dimming glass in the embodiments of the present application. In this embodiment, the dimming glass is still used for the left and right side windows as an example.

[0095] In some embodiments, Figure 4 the interface shown can be displayed on the central control screen of the vehicle, the rear activity screen, and / or in an application for vehicle control in an electronic device (such as a mobile phone). In the following description, it is assumed that the interface is displayed on the central control screen of the vehicle. Figure 4 The following takes the interface shown as an example.

[0096] Referring to Figure 4 , the vehicle can provide a window control interface 410 for the user. In the window control interface 410, a dimming gear adjustment control 401 can be set to trigger the gear adjustment of the window. When the user clicks the dimming gear adjustment control 401, correspondingly, the vehicle detects a selection operation for the dimming gear adjustment control 401 and displays a dimming gear adjustment interface 420.

[0097] The dimming gear adjustment interface 420 can be set with different dimming items, and each item corresponds to a control. For example, Figure 4 the dimming items shown in include: the left front door window, the right front door window, the left rear door window, the right rear door window, the linkage of the left and right front door windows, the linkage of the left and right rear door windows, the linkage of the left side door windows, the linkage of the right side door windows, and the linkage of all door windows. It can be understood that different dimming items can correspond to different dimming objects. Taking the dimming item of the left rear door window as an example, the dimming objects can include the fixed glass of the left rear door, the lifting glass of the left rear door, and the triangular glass of the left rear door. Other items will not be listed one by one. It can be understood that the above dimming items are only examples, and in actual applications, the above items can be removed, added, split, or combined according to the possible dimming needs of vehicle users. The embodiments of the present application do not make restrictions.

[0098] Assume that the dimming item selected by the user is the left rear door window. When the user clicks the control corresponding to the left rear door window, correspondingly, the vehicle detects a selection operation for the control corresponding to the left and right door windows and can display a left rear door window gear adjustment interface 430.

[0099] The left rear door window gear adjustment interface 430 can be set with controls corresponding to different gears. Figure 4It is assumed that there are a total of 4 gears, namely gear 0 to gear 3. The current gear of the left rear door window is gear 0, and the control 403 corresponding to gear 0 is highlighted to prompt the user of the current gear. If the user wishes to adjust to gear 3, the user can click on the control 404 corresponding to gear 3. Correspondingly, the vehicle can detect the user's selection operation for the control 404 corresponding to gear 3, that is, detect the user operation of adjusting the left rear door window from gear 0 to gear 3, which can trigger the execution of the gear control method of the dimming glass in the embodiment of the present application, and decide whether the left rear door window can be adjusted from gear 0 to gear 3. If it cannot be adjusted to gear 3, the user can be prompted that the gear adjustment fails. If it can be adjusted to gear 3, the vehicle adjusts the gear of the left rear door window to gear 3, and the left rear door window gear adjustment interface 430 can update the interface and highlight the control 404 corresponding to gear 3 to prompt the user that the gear has been adjusted to gear 3.

[0100] The above prompt for the user that the gear adjustment fails can be, for example, to display the gear adjustment failure prompt interface shown in the interface 440 and / or play the prompt voice for the gear adjustment failure. Figure 4 as shown in the interface 440 and / or play the prompt voice for the gear adjustment failure.

[0101] In other embodiments, in addition to prompting the user that the gear adjustment fails, the vehicle can also recommend other gears that the left rear door window currently supports adjustment for the user to refer to, so as to improve the user experience.

[0102] It can be understood that the above interface implementation is only an example and is not used to limit the actual interface implementation in the vehicle.

[0103] The gear control method of the dimming glass in the embodiment of the present application will be described in more detail below in combination with the above description.

[0104] In an embodiment provided by the present application, when it is necessary to adjust the target dimming glass on the vehicle from the first gear to the second gear, it is determined whether the target dimming glass can be adjusted to the second gear based on the real-time temperature measurement value of the target dimming glass. When the real-time temperature measurement value of the target dimming glass is too high, the gear adjustment of the dimming glass is restricted to reduce the influence of high temperature on the service life of the dimming glass and extend the service life of the dimming glass.

[0105] Among them, the above first gear and second gear can be any two gears in the gears of the target dimming glass.

[0106] Among them, the above-mentioned target dimming glass is not limited to one piece of glass. In other words, it can be any one or more dimming glasses on the vehicle. Figure 2 Taking the window configuration shown as an example, the target dimming glass can be the lifting glass of the left rear door, or can be the fixed glass, lifting glass and triangular glass of the left rear door, etc., which will not be listed one by one here.

[0107] In some embodiments, the target dimming glass may specifically be an EC dimming glass.

[0108] Figure 5 FIG. is a schematic flow chart of a method for controlling the gear of the dimming glass provided in an embodiment of the present application. This method may be executed by a vehicle, specifically by a controller where the target dimming glass is located in the vehicle. Taking the target dimming glass as the left window of the vehicle as an example, this method may be executed by the left window controller.

[0109] As Figure 5 shown, this method may include:

[0110] Step 501: Detect a trigger condition for adjusting the gear of the target dimming glass from the first gear to the second gear.

[0111] The implementation of this step may refer to the corresponding description in the subsequent embodiments and will not be elaborated here.

[0112] Step 502: Obtain a first temperature value of the target dimming glass.

[0113] In some embodiments, the first temperature value may specifically be a real-time temperature measurement value of the target dimming glass.

[0114] In some embodiments, if the target dimming glass is a single dimming glass, a temperature sensor may be provided on or near the target dimming glass, and the real-time temperature value detected by the temperature sensor may be used as the first temperature value of the target dimming glass.

[0115] In some embodiments, if the target dimming glass is multiple dimming glasses, a temperature sensor may be provided on or near one of the dimming glasses, and the real-time temperature value detected by the temperature sensor may be used as the first temperature value of the target dimming glass.

[0116] In some embodiments, if the target dimming glass is multiple dimming glasses, multiple temperature sensors may be provided on or near the multiple dimming glasses. At this time, the first temperature value of the target dimming glass may be calculated based on the multiple real-time temperature values detected by the multiple temperature sensors. The specific calculation method is not limited in the embodiments of the present application. For example, the multiple real-time temperature values may be averaged, the median value may be taken, or weighted summation may be performed.

[0117] In some embodiments, the real-time temperature value detected by the above temperature sensor may specifically be the latest temperature value detected by the temperature sensor before, when, or after triggering the execution of this step.

[0118] Step 503: Determine whether the target dimming glass supports operating in the second gear at the first temperature value. If it supports, execute Step 504; if not, execute Step 505.

[0119] In some embodiments, control information (corresponding to the above-mentioned third information) indicating whether the dimming glass supports operating in each gear at different temperature intervals (corresponding to the above-mentioned third temperature interval) can be preset. The control information may record the light transmittance corresponding to the combination of different temperature intervals and different gears. For the gears that the dimming glass does not support in a certain temperature interval, the light transmittance corresponding to the combination of this temperature interval and the gear may be missing or recorded as a special identifier.

[0120] In this step, the temperature interval where the first temperature value is located can be determined first, and the first light transmittance corresponding to the combination of the temperature interval where the first temperature value is located and the target gear is searched from the above control information. If the corresponding first light transmittance is found, it means that the target dimming glass supports operating in the second gear at the first temperature value; if the corresponding first light transmittance is not found, it means that the target dimming glass does not support operating in the second gear at the first temperature value.

[0121] The above-mentioned temperature intervals can be obtained by dividing the possible temperature range of the dimming glass. The temperature intervals are independent of each other, do not have overlapping temperatures, and the union of the temperature intervals can constitute the possible temperature range of the dimming glass.

[0122] For example, the above control information is shown in Table 1 below. It is assumed that the possible temperature range of the dimming glass is divided into 7 temperature intervals: ultra-low temperature zone, low temperature zone, normal temperature zone, medium temperature zone, medium-high temperature zone, high temperature zone, and ultra-high temperature zone. The temperatures included in the 7 temperature intervals increase in sequence from the ultra-low temperature zone to the ultra-high temperature zone.

[0123] It should be noted that the specific temperatures included in the above 7 temperature intervals are not limited in the embodiments of the present application and can be determined by methods such as pre-calibration in practical applications. Exemplarily, assuming that the possible temperature range of the dimming glass is -50 to 100 degrees, it can be divided into: ultra-low temperature zone [-50, -20], low temperature zone (-20, 0], normal temperature zone (0, 25], medium temperature zone (25, 30], medium-high temperature zone (35, 40], high temperature zone (40, 45], ultra-high temperature zone (45, 100].

[0124] In addition, it is assumed in Table 1 that the gears of the dimming glass are divided into 4 gears from gear 0 to gear 3. From gear 0 to gear 3, the light transmittance increases in sequence, that is, the values of TL0, TL1, TL2, and TL3 increase in sequence. It can be understood that the number of gears of the dimming glass is not limited in the embodiments of the present application, and the above division into 4 gears is only an example. TL0, TL1, TL2, and TL3 respectively represent light transmittances with different values.

[0125] Assume that the first temperature value is in the medium temperature range and the second gear is gear 2. Since the light transmittance TL2 corresponding to the combination of the medium temperature range and gear 2 can be found in Table 1, in this step, it can be determined that the target dimming glass supports operating in gear 2 at the first temperature value.

[0126] Assume that the first temperature value is in the high temperature range and the second gear is gear 1. Since the light transmittance corresponding to the combination of the high temperature range and gear 1 is missing in Table 1, the light transmittance corresponding to the combination of the high temperature range and gear 1 cannot be found in Table 1. Therefore, in this step, it can be determined that the target dimming glass does not support operating in gear 1 at the first temperature value.

[0128] Table 1

[0129] In some embodiments, in order to further refine the control of the target dimming glass, different light transmittances can be further set for the combination of the same gear and different temperature ranges in the preset control information. For example, in Table 2, the light transmittance corresponding to the combination of gear 3 and the low temperature range is TL3*n1, while the light transmittance corresponding to the combination of gear 3 and each temperature range from the normal temperature range to the high temperature range is TL3; the light transmittances corresponding to the combination of gear 1 and each temperature range from the low temperature range to the medium-high temperature range are all different.

[0130] That is to say, in the preset control information of the embodiments of the present application, the light transmittances corresponding to the combination of the same gear and different temperature ranges can be the same or different.

[0132] Table 2

[0133] It should be noted that the setting of the light transmittance corresponding to the combination of different temperature ranges and different gears in Table 2 is only an example and is not intended to limit the setting of the light transmittance corresponding to the combination of different temperature ranges and different gears in actual applications.

[0134] It should be noted that if it is still assumed that the light transmittance increases in sequence from gear 0 to gear 3, the light transmittances TL0 / n01, TL0, TL0 / n02, and TL0 / n03 corresponding to gear 0 are all less than TL1, and the light transmittances TL3*n1 and TL3 corresponding to gear 3 are both greater than the light transmittance TL2 corresponding to gear 2.

[0135] It should be noted that the above n01, n02, n03, and n1 can be pre-calibrated coefficients used to represent the correlation between the light transmittances corresponding to different temperature ranges in the same gear. In practical applications, the specific value of TL3 * n1 can be directly set in the vehicle, and it is not necessary to calculate the value of TL3 * n1 in real time. The same applies to TL0 / n01, TL0 / n02, and TL0 / n03, which will not be elaborated here.

[0136] In some embodiments, the above n1, n01, n02, and n03 can be numbers greater than 1.

[0137] In the above embodiments, the control information on whether the preset dimming glass supports working in each gear at different temperature ranges is implemented by recording the light transmittances corresponding to the combinations of different temperature ranges and different gears. The light transmittance corresponding to a combination of a certain temperature range and a certain gear not only includes the meaning of whether it supports working in a certain gear at the above certain temperature range but also indicates the light transmittance corresponding to the combination. In other embodiments, the content included in the above control information can be implemented through the first sub-information and the second sub-information. The first sub-information (corresponding to Table 3) is used to record, with different identifiers, whether the dimming glass supports working in each gear at different temperature ranges, and the second sub-information (corresponding to Table 4) is used to record the light transmittances corresponding to the combinations of different temperature ranges and different gears. The above identifiers can include two types, one indicating support and the other indicating non-support.

[0138] At this time, to determine whether the target dimming glass supports working in the second gear at the first temperature value according to the first temperature value, it can include: finding the identifier corresponding to the combination of the temperature range where the first temperature value is located and the second gear from the first sub-information, and determining whether the target dimming glass supports working in the second gear at the first temperature value based on this identifier.

[0139] For example, the content recorded in the above Table 2 can also be recorded through the following Tables 3 and 4. Among them, in Table 3, 0 and 1 are used as identifiers to record whether the dimming glass supports working in each gear at different temperature ranges, where 0 indicates non-support and 1 indicates support; Table 4 records the light transmittances corresponding to the combinations of different temperature ranges and different gears. At this time, it is not necessary to record the information corresponding to the missing part of the light transmittance in Table 2 in Table 4. Then, assuming that the first temperature value is in the medium temperature range and the second gear is the 2nd gear, the identifier found from Table 3 is 1, indicating that the target dimming glass supports working in the 2nd gear in the medium temperature range, so it can be determined that the target dimming glass supports working in the second gear at the first temperature value. Assuming that the first temperature value is in the high temperature range and the second gear is the 1st gear, the corresponding identifier found from Table 3 is 0, indicating that the target dimming glass does not support working in the 1st gear in the high temperature range, so it can be determined that the target dimming glass does not support working in the second gear at the first temperature value.

[0144] Table 4

[0145] In other embodiments, in order to improve the gear control accuracy of the dimming glass, the control information on whether the preset dimming glass supports working in each gear in different temperature ranges can be further extended to the control information on whether the preset dimming glass supports working in each gear at different temperatures. At this time, in this step, the first light transmittance corresponding to the combination of the first temperature value and the second gear can be directly found from the control information, or the identifier corresponding to the combination of the first temperature value and the second gear can be found from the first sub-information, without first determining the temperature range where the first temperature value is located. Similarly, the second sub-information can also be extended in a similar manner.

[0146] Step 504: Adjust the target dimming glass to the second gear, and this branch process ends.

[0147] Continuing with the example in step 503, in some embodiments, when the first light transmittance corresponding to the combination of the temperature range where the first temperature value is located and the second gear is found from the above control information in step 503, or when the first light transmittance corresponding to the combination of the first temperature value and the second gear is found, this step may further include: adjusting the light transmittance of the target dimming glass to the first light transmittance.

[0148] Continuing with the distance in step 503, in other embodiments, if the control information includes the first sub-information and the second sub-information, this step may further include: finding the first light transmittance corresponding to the combination of the temperature range where the first temperature value is located and the second gear from the second sub-information, and adjusting the light transmittance of the target dimming glass to the first light transmittance; or, finding the first light transmittance corresponding to the combination of the first temperature value and the second gear from the second sub-information, and adjusting the light transmittance of the target dimming glass to the first light transmittance.

[0149] In some embodiments, the gear parameters of the target dimming glass may be set in the vehicle. Specifically, adjusting the target dimming glass to the second gear in this step may include: updating the gear parameters of the target dimming glass to the second gear.

[0150] Step 505: Keep the target dimming glass unchanged in the first gear, and prompt the user that the gear adjustment fails, and this branch process ends.

[0151] Reference ​According to the description in [reference], the failure prompt for the user's gear adjustment in this step can be achieved by popping up a prompt box on the vehicle's central control screen and / or playing voice, etc., and the embodiments of the present application do not limit this.

[0152] In other embodiments, in addition to prompting the user that the gear adjustment fails, the gear that the target dimming glass can support at the first temperature value can also be found from the above control information or the first sub-information, and a gear other than the first gear in the above gears can be recommended to the user.

[0153] In other embodiments, the vehicle can also find the gear that the target dimming glass can support at the first temperature value from the above control information or the first sub-information. If there is a gear between the first gear and the second gear among the found gears, one gear can be selected from them, the target dimming glass can be adjusted from the first gear to the selected gear, and the user can be prompted. For example, assuming that the first temperature value is in the high temperature zone, the first gear is gear 3, and the second gear is gear 0, then in this step, the gears that the target dimming glass can support at the first temperature value can be obtained as gear 3 and gear 2. Gear 2 can be selected, the target dimming glass can be adjusted from gear 3 to gear 2, and the light transmittance of the target dimming glass can be adjusted to the light transmittance corresponding to the high temperature zone and gear 2. Correspondingly, the vehicle can prompt the user that it cannot be adjusted to gear 0 and has adjusted the gear to gear 2. This embodiment can reduce user operations and improve the user experience.

[0154] ​ In the gear control method of the dimming glass shown, based on the first temperature value of the dimming glass, it is determined whether the target dimming glass can be adjusted to the second gear. By restricting the gear adjustment of the target dimming glass when the first temperature value of the target dimming glass is too high, the influence of unreasonable gear adjustment at high temperature on the life of the target dimming glass can be reduced, and the life of the dimming glass can be extended.

[0155] The following combines ​ and ​ to give an exemplary illustration of the possible implementation of detecting the trigger condition for adjusting the gear of the target dimming glass to the second gear in step 501.

[0156] Referring to ​ , the target dimming glass can be triggered to be adjusted from the first gear to the second gear by the user's operation. Specifically, if the vehicle receives the user's operation of adjusting the gear of the target dimming glass from the first gear to the second gear, it can be considered that the trigger condition for detecting the adjustment of the gear of the target dimming glass from the first gear to the second gear is detected. The implementation of the above user operation can refer to the corresponding description in ​ , and will not be elaborated here.

[0157] Referring to ​, after the vehicle is powered on, the vehicle can determine whether the gear adjustment of the target dimming glass is in the automatic adjustment mode. If so, the vehicle can automatically adjust the gear of the target dimming glass in the automatic adjustment mode. At this time, if the vehicle generates an automatic decision to adjust the gear of the target dimming glass from the first gear to the second gear, it can be considered that the trigger condition for adjusting the gear of the target dimming glass from the first gear to the second gear is detected.

[0158] Alternatively, if the gear adjustment of the target dimming glass is not in the automatic adjustment mode, the vehicle can determine whether the time interval between the current vehicle power-on time and the previous vehicle power-off time is less than the preset time threshold T. If it is less, the historical information that the target dimming glass was in the second gear at the previous vehicle power-off can be obtained, and it is determined to adjust the gear of the target dimming glass to the second gear. Correspondingly, it can be considered that the trigger condition for adjusting the gear of the target dimming glass from the first gear to the second gear is detected. Here, the first gear is the current gear of the target dimming glass, and the second gear is the second gear in the above historical information.

[0159] If the time interval between the current vehicle power-on time and the previous vehicle power-off time is greater than the preset time threshold, the default gear of the target dimming glass can be obtained, and it is determined to adjust the gear of the target dimming glass to the default gear. Correspondingly, it can be considered that the trigger condition for adjusting the gear of the target dimming glass from the first gear to the second gear is detected. Here, the first gear is the current gear of the target dimming glass, and the second gear is also the above default gear.

[0160] It can be understood that the above trigger conditions are only examples, and the embodiments of the present application are not limited to the above trigger conditions, as long as they can trigger the target dimming glass to adjust the gear.

[0161] In some embodiments, due to the location of the temperature sensor and the influence of the detection accuracy of the temperature sensor, etc., the first temperature value (real-time temperature measurement value) of the target dimming glass detected by the temperature sensor often has a certain deviation from the actual temperature value of the target dimming glass. Especially when the temperature sensor used to detect the target dimming glass is not located on the target dimming glass, this deviation will be more serious. The following is an exemplary description.

[0162] In an embodiment provided by the present application, if the dimming glass is used as the side window of the vehicle, due to the space layout limitation and cost reasons around the vehicle side window, only a small number of temperature sensor probes can be arranged on the dimming glass of the side window, for example ​ As shown, only one NTC probe can be set in the black edge of the triangular glass of the left and right rear doors respectively to measure the real-time temperature of the left side window and the right side window respectively. At this time, there is often a deviation between the temperature value measured by the NTC probe and the actual temperature value of each side window glass.

[0163] See ​ As shown, multiple temperature-time curves are shown. The blue curve is the real-time temperature value measured by the NTC probe within a period of time, and the curves of other colors are the actual temperature values of each window within the same period of time. It can be seen that at an ambient temperature of 40 degrees, there is a certain deviation between the actual temperature values of the windows at different positions and the real-time temperature value measured by the NTC probe.

[0164] The difference-time curve between the actual temperature value of a certain window and the real-time temperature value of the NTC probe, for example ​ As shown, it can be seen that the differences at different times are small and large. The small differences are between 1 and 1.5 degrees, while the large differences are about 5.5 degrees. In view of this, ​ In the method shown, directly determining whether the dimming glass can be adjusted to the second gear based on the first temperature value of the dimming glass and performing gear adjustment based on the judgment result may still have a certain risk of gear error, which may affect the service life of the dimming glass. Especially in the case of large differences, this impact is greater.

[0165] For this reason, the embodiment of the present application also provides a method for controlling the gear of the dimming glass, which performs temperature compensation on the first temperature value of the dimming glass on the basis of the method shown in ​ to further extend the service life of the dimming glass, so that when the dimming glass, such as the EC dimming glass, is applied to a vehicle, the service life is closer to or meets the life requirements of vehicle regulations.

[0166] ​ FIG. is a schematic flowchart of an implementation of the method for controlling the gear of the dimming glass provided by the embodiment of the present application. As shown in ​ shown, the method may include:

[0167] Step 1001: Detect a trigger condition for adjusting the gear of the target dimming glass from the first gear to the second gear;

[0168] The implementation of this step can refer to step 501 in ​ and will not be elaborated here.

[0169] Step 1002: Obtain the first temperature value of the target dimming glass.

[0170] The implementation of this step can refer to step 502 in ​ and will not be elaborated here.

[0171] Step 1003: Obtain a first temperature compensation value, and perform temperature compensation on the first temperature value according to the first temperature compensation value to obtain a second temperature value.

[0172] Among them, the first temperature compensation value is used to compensate for the difference between the first temperature value and the actual temperature value of the target dimming glass.

[0173] In some embodiments, the above temperature compensation of the first temperature value according to the first temperature compensation value to obtain the second temperature value may specifically include: calculating the sum of the first temperature compensation value and the first temperature value as the second temperature value.

[0174] For the specific implementation of obtaining the first temperature compensation value in this step, please refer to the subsequent corresponding description, which will not be elaborated here.

[0175] Step 1004: Determine whether the target dimming glass supports operating in the second gear at the second temperature value. If yes, execute Step 1005; if not, execute Step 1006.

[0176] The implementation of this step can refer to ​ Step 503 in, with the main difference being that the first temperature value is replaced by the second temperature value in this step.

[0177] Step 1005: Adjust the gear of the target dimming glass from the first gear to the second gear, and this branch process ends.

[0178] The implementation of this step can refer to ​ Step 504 in, which will not be elaborated here.

[0179] Step 1006: Keep the target dimming glass at the first gear unchanged and prompt the user that the gear adjustment fails, and this branch process ends.

[0180] The implementation of this step can refer to ​ Step 505 in, which will not be elaborated here.

[0181] ​ In the method shown, the first temperature value is temperature-compensated by the first temperature compensation value to obtain the second temperature value, so that the second temperature value is closer to the actual temperature value of the target dimming glass. Therefore, when determining whether to adjust the target dimming glass to the second gear based on the second temperature value, compared with ​ the shown embodiment can achieve more precise gear adjustment control, reduce the impact of unreasonable gear adjustment at high temperatures on the life of the target dimming glass, and extend the life of the target dimming glass.

[0182] The following gives an exemplary illustration of the specific implementation of obtaining the first temperature compensation value in Step 1003.

[0183] In the first embodiment, the temperature compensation value (corresponding to the aforementioned third temperature value) can be preset, and then the preset temperature compensation value can be directly obtained as the first temperature compensation value in Step 1003.

[0184] Among them, the temperature compensation value can be obtained by a pre-calibration method. For example, when the ambient temperature is high (e.g., 40 degrees), the actual temperature values of the target dimming glass at different times (with different light intensities) and the real-time measured values of the corresponding temperature sensors of the target dimming glass can be pre-measured, and the difference between the real-time measured value and the actual temperature value at different times can be obtained, and then a difference-time curve similar to that shown in ​ is obtained, and the temperature compensation value is determined based on this difference-time curve. For example, the maximum difference, or the minimum difference, or the average value of the differences, or the median value of the differences in the difference-time curve can be taken as the temperature compensation value.

[0185] In the second embodiment, referring to ​ it can be seen that under the same ambient temperature and light intensity, the actual temperature values of the dimming glasses at different positions on the vehicle are different. Therefore, corresponding temperature compensation values can be set in advance for each dimming glass in the vehicle to achieve a more accurate temperature compensation effect. Then, in step 1003, the temperature compensation value corresponding to the target dimming glass (corresponding to the aforementioned fourth temperature value) can be obtained as the first temperature compensation value.

[0186] If the target dimming glass includes multiple dimming glasses, the temperature compensation value corresponding to a certain target dimming glass, or the average value of the temperature compensation values corresponding to the above multiple dimming glasses, etc. can be taken as the first temperature compensation value.

[0187] Among them, the temperature compensation value corresponding to each dimming glass can also be obtained by pre-calibration. The calibration method can refer to the description in the first embodiment and will not be elaborated here.

[0188] In the third embodiment, obtaining the first temperature compensation value in step 1003 can specifically include: determining the first temperature compensation value according to the first target parameter.

[0189] Among them, the first target parameter includes the parameter that can affect the temperature of the target dimming glass. In some embodiments, the first target parameter may include at least one of the following: the light level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located.

[0190] Among them, the possible value range of the light intensity can be pre-divided to obtain multiple independent light intensity ranges. Each light intensity range corresponds to a light level. The greater the light intensity included in the light intensity range, the higher the light level corresponding to the light intensity range. The number of light levels is not limited in the embodiments of the present application, and the specific division method of the light levels is not limited in the embodiments of the present application. In an example, 2 light levels can be set, and the boundary value between the 2 light levels is 5. When the light intensity is less than or equal to 5, the light level is level 1; when the light intensity is greater than 5, the light level is level 2.

[0191] In a possible implementation manner, the vehicle can obtain the real-time light intensity from the sunlight and rain sensor in the vehicle as the light intensity received by the target dimming glass, determine the light level corresponding to the light intensity, and obtain the light level received by the target dimming glass.

[0192] In another possible implementation manner, the vehicle can also determine the geographical location where the vehicle is located based on the positioning system, determine the light intensity at the geographical location at the current time based on the weather forecast information of the geographical location where the vehicle is located, and determine the light level received by the target dimming glass based on the light intensity.

[0193] In a possible implementation manner, the vehicle can obtain the real-time temperature value from the body environment temperature sensor in the vehicle as the ambient temperature of the environment where the target dimming glass is located. In another possible implementation manner, the vehicle can determine the ambient temperature at the geographical location at the current time based on the weather forecast information of the geographical location where the vehicle is located as the ambient temperature of the environment where the target dimming glass is located.

[0194] Compared with the foregoing first embodiment and second embodiment, this embodiment can have a relatively more accurate temperature compensation effect in various vehicle use scenarios, so that the second temperature value obtained after temperature compensation is closer to the actual temperature value of the target dimming glass. Thus, under the condition of preventing unreasonable control of the target dimming glass gear, it can try to ensure the reasonable gear adjustment and use of the target dimming glass by passengers during the vehicle ride. Therefore, compared with the first embodiment and the second embodiment, it can provide a better user experience for users.

[0195] The following gives an exemplary description of the possible implementation of determining the first temperature compensation value according to the first target parameter.

[0196] In the first embodiment, the first temperature compensation value can be determined according to the light level received by the target dimming glass. Specifically, the temperature compensation values corresponding to different light levels can be preset, and the higher the light level, the larger the temperature compensation value corresponding to the light level. The temperature compensation value corresponding to each light level can be obtained through pre-calibration. Then, determining the first temperature compensation value according to the first target parameter may specifically include: obtaining the temperature compensation value corresponding to the light level received by the target dimming glass as the first temperature compensation value.

[0197] In the second embodiment, the first temperature compensation value can be determined according to the ambient temperature of the environment where the target dimming glass is located.

[0198] In a possible implementation, the temperature compensation values corresponding to different ambient temperatures can be preset, and the higher the ambient temperature, the larger the temperature compensation value corresponding to the ambient temperature. The temperature compensation value corresponding to each ambient temperature can be obtained through pre-calibration. Then, determining the first temperature compensation value according to the first target parameter may specifically include: obtaining the temperature compensation value corresponding to the ambient temperature of the environment where the target dimming glass is located as the first temperature compensation value.

[0199] In another possible implementation, the functional relationship between the ambient temperature and the temperature compensation value can be preset. Then, determining the first temperature compensation value according to the first target parameter may specifically include: calculating the first temperature compensation value based on the ambient temperature of the environment where the target dimming glass is located and the functional relationship.

[0200] In still another possible implementation, the temperature compensation values corresponding to different temperature ranges can also be preset. The higher the temperature included in the temperature range, the larger the temperature compensation value corresponding to the temperature range. Then, determining the first temperature compensation value according to the first target parameter may specifically include: determining the temperature range to which the ambient temperature of the environment where the target dimming glass is located belongs, and obtaining the temperature compensation value corresponding to the temperature range as the first temperature compensation value. The temperature range division method in this implementation may be different from ​ the temperature range division method therein. The specific temperature range division method will not be elaborated here.

[0201] In the third embodiment, the first temperature compensation value can be determined according to the driving speed of the vehicle where the target dimming glass is located.

[0202] In a possible implementation, the temperature compensation values corresponding to different driving speeds can be preset, and the higher the driving speed, the smaller the temperature compensation value corresponding to the ambient temperature. The temperature compensation value corresponding to each driving speed can be obtained through pre-calibration. Then, determining the first temperature compensation value according to the first target parameter may specifically include: obtaining the temperature compensation value corresponding to the driving speed of the vehicle where the target dimming glass is located as the first temperature compensation value.

[0203] In another possible implementation, a functional relationship between the driving speed and the temperature compensation value may also be preset. Then, determining the first temperature compensation value according to the first target parameter may specifically include: calculating the first temperature compensation value based on the driving speed of the vehicle where the target dimming glass is located and the preset functional relationship.

[0204] In yet another possible implementation, temperature compensation values corresponding to different speed intervals may also be preset. The higher the speed included in the speed interval, the smaller the temperature compensation value corresponding to the speed interval. Then, determining the first temperature compensation value according to the first target parameter may specifically include: determining the speed interval to which the driving speed of the vehicle where the target dimming glass is located belongs, and obtaining the temperature compensation value corresponding to the speed interval as the first temperature compensation value. The method for dividing the above speed intervals is not limited in the embodiments of the present application.

[0205] In the fourth embodiment, the first temperature compensation value may be determined according to two or three of the light intensity level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located.

[0206] For the relationship between each parameter and the first temperature compensation value, please refer to the corresponding descriptions in the first to third embodiments.

[0207] The following takes determining the first temperature compensation value according to the light intensity level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located as an example for illustration.

[0208] In the vehicle, temperature compensation values corresponding to combinations of different light intensity levels, temperature intervals, and speed intervals may be preset. Under the same light intensity level and temperature interval, the higher the speed included in the speed interval, the smaller the temperature compensation value corresponding to the combination; under the same light intensity level and speed interval, the higher the temperature included in the temperature interval, the larger the temperature compensation value corresponding to the combination; under the same temperature interval and speed interval, the higher the light intensity level, the larger the temperature compensation value corresponding to the combination. Then,

[0209] Determining the first temperature compensation value according to the first target parameter may specifically include: determining the temperature interval where the ambient temperature of the environment where the target dimming glass is located is located, determining the speed interval corresponding to the driving speed of the vehicle where the target dimming glass is located, and obtaining the temperature compensation value corresponding to the combination of the light intensity level, temperature interval, and speed interval corresponding to the target dimming glass as the first temperature compensation value.

[0210] The implementation of determining the first temperature compensation value according to any two of the light intensity level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located may refer to the example of determining the first temperature compensation value according to three parameters described above, and will not be listed one by one here.

[0211] In the fifth embodiment, in order to further improve the temperature compensation accuracy, the first temperature compensation value may also be determined by combining the first temperature value on the basis of the first target parameter. At this time, determining the first temperature compensation value according to the first target parameter may include:

[0212] Determine the first temperature compensation value according to the first target parameter and the first temperature value.

[0213] The following is an exemplary description of the possible implementation of determining the first temperature compensation value according to the first target parameter and the first temperature value.

[0214] In the first embodiment, the first target parameter may include the driving speed of the vehicle where the target dimming glass is located; at this time, determining the first temperature compensation value according to the first target parameter and the first temperature value, that is, determining the first temperature compensation value according to the driving speed of the vehicle where the target dimming glass is located and the first temperature value.

[0215] In a possible implementation manner, determining the first temperature compensation value according to the driving speed of the vehicle where the target dimming glass is located and the first temperature value may specifically include:

[0216] Determine the speed range in which the driving speed of the vehicle where the target dimming glass is located is located;

[0217] Determine the first temperature range in which the first temperature value is located;

[0218] Find the temperature compensation value corresponding to the combination of the speed range and the first temperature range in which the first temperature value is located from the preset first information as the first temperature compensation value; the temperature compensation values corresponding to the combinations of different speed ranges and first temperature ranges are recorded in the preset first information.

[0219] The division methods of the speed range and the first temperature range here may be different from those of the speed range and the temperature range in the foregoing embodiments, and the embodiments of the present application do not limit this. The "first" in the first temperature range here is used to distinguish it from the temperature ranges in other embodiments.

[0220] In some embodiments, in the first information, for the combinations formed by the same first temperature range and different speed ranges, the temperature compensation value corresponding to the combination in which the speed range with a relatively larger speed is located is relatively smaller; for the combinations formed by the same speed range and different first temperature ranges, the temperature compensation value corresponding to the combination in which the temperature range with a relatively lower temperature is located is relatively smaller.

[0221] The following is an example.

[0222] As shown in Table 5 below, examples of the first information are shown. Among them, the speed ranges include: (0 km / h, 30 km / h], (30 km / h, 60 km / h], (60 km / h, 100 km / h], (100 km / h, +∞), and the first temperature ranges include: (35 °C, 40 °C], (40 °C, 45 °C],

[0223] (45 °C, +∞), and the first temperature range below 35 °C is not shown.

[0224]

[0225] Table 5

[0226] In Table 5, for the temperature compensation values in each row, they can increase sequentially from left to right, and for the temperature compensation values in each column, they can decrease sequentially from top to bottom. For example, for the temperature compensation values in the first row, ΔT3 > ΔT2 > ΔT1, and for the temperature compensation values in the first column, ΔT1 > ΔT4 > ΔT7 > ΔT10.

[0227] Assume that the driving speed is 45 km / h and the first temperature value of the target dimming glass is 38 °C. Then, it can be determined that the speed range where the driving speed is located is (30 km / h, 60 km / h], and the first temperature range where the first temperature value is located is (35 °C, 40 °C]. By looking up Table 5, the corresponding temperature compensation value can be obtained as ΔT4, so the first temperature compensation value is ΔT4.

[0228] In the second embodiment, the first target parameter may include the light level received by the target dimming glass. At this time, the first temperature compensation value is determined according to the first target parameter and the first temperature value, that is, the first temperature compensation value is determined according to the light level received by the target dimming glass and the first temperature value.

[0229] The implementation of this embodiment can refer to the aforementioned first embodiment. The main difference is that the speed range is replaced by the light level. Then, the first temperature compensation value is determined according to the light level received by the target dimming glass and the first temperature value, which may specifically include:

[0230] Determine the first temperature range where the first temperature value is located;

[0231] Find the temperature compensation value corresponding to the combination of the light level and the first temperature range from the preset first information as the first temperature compensation value; the preset first information records the temperature compensation values corresponding to the combinations of different light levels and first temperature ranges.

[0232] In this embodiment, in the first piece of information, for a combination of the same light level and different first temperature ranges, the larger the temperature included in the first temperature range, the relatively larger the temperature compensation value corresponding to the combination. For a combination of the same first temperature range and different light levels, the smaller the light level, the smaller the temperature compensation value corresponding to the combination.

[0233] In the third embodiment, the first target parameter may include the ambient temperature of the environment where the target dimming glass is located. At this time, the first temperature compensation value is determined according to the first target parameter and the first temperature value, that is, the first temperature compensation value is determined according to the ambient temperature of the environment where the target dimming glass is located and the first temperature value.

[0234] The implementation of this embodiment can refer to the foregoing first embodiment. The main difference is that the speed range is replaced by the ambient temperature range. Then, determining the first temperature compensation value according to the ambient temperature of the environment where the target dimming glass is located and the first temperature value may specifically include:

[0235] Determine the ambient temperature range in which the ambient temperature of the environment where the target dimming glass is located is located;

[0236] Determine the first temperature range in which the first temperature value is located;

[0237] Find the temperature compensation value corresponding to the combination of the ambient temperature range and the first temperature range of the target dimming glass from the preset first piece of information as the first temperature compensation value; the preset first piece of information records the temperature compensation values corresponding to the combinations of different ambient temperature ranges and first temperature ranges.

[0238] In this embodiment, in the first piece of information, for a combination of the same ambient temperature range and different first temperature ranges, the larger the temperature included in the first temperature range, the relatively larger the temperature compensation value corresponding to the combination. For a combination of the same first temperature range and different ambient temperature ranges, the larger the temperature included in the ambient temperature range, the larger the temperature compensation value corresponding to the combination.

[0239] In the fourth embodiment, the first target parameter may include two or three of the light level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located. At this time, the implementation of determining the first temperature compensation value according to the first target parameter and the first temperature value can refer to the foregoing first to third embodiments. The main difference is that the number of dimensions included in the first piece of information is increased from two dimensions to three or four dimensions, and the relationship between each dimension and the temperature compensation value is the same as that in the first to third embodiments. The corresponding temperature compensation value can be found according to the combination of the parameters of the above multiple dimensions in the first piece of information and used as the first temperature compensation value. The embodiments of the present application will not be enumerated one by one.

[0240] In another embodiment provided by the present application, as ​ shown, between step 1002 and step 1003 of the method shown in ​ the following step 1101 may further be included.

[0241] Step 1101: Obtain a second target parameter, and determine whether to perform temperature compensation on the first temperature value according to the second target parameter. If yes, execute step 1003. If no, execute steps 503 to 505 in the foregoing embodiment.

[0242] Wherein, the second target parameter includes a parameter that can affect the temperature of the target dimming glass.

[0243] In some embodiments, the second target parameter may include at least one of the following: the light level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, and the driving speed of the vehicle where the target dimming glass is located.

[0244] In this method, only the first temperature value that meets the requirements is temperature-compensated, so that the data processing amount of the vehicle can be reduced, and the gear adjustment speed of the dimming glass is improved under the condition of ensuring the service life of the dimming glass.

[0245] The following gives an exemplary illustration of the possible implementation of determining whether to perform temperature compensation on the first temperature value according to the second target parameter in step 1101.

[0246] In the first embodiment, the second target parameter may include the light level received by the target dimming glass and the ambient temperature of the environment where the target dimming glass is located. Then, determining whether to perform temperature compensation on the first temperature value according to the second target parameter may include:

[0247] Determine the second temperature range in which the ambient temperature of the target dimming glass is located;

[0248] Find the indication information corresponding to the combination of the light level and the second temperature range from the preset second information; the indication information is used to indicate whether to perform temperature compensation on the first temperature value; the second information records the indication information corresponding to different combinations of the light level and the second temperature range;

[0249] Determine whether the indication information is the first indication information.

[0250] Wherein, the first indication information is used to indicate performing temperature compensation on the first temperature value, and the second indication information is used to indicate not performing temperature compensation on the first temperature value.

[0251] In some embodiments, in the second information, the indication information corresponding to the combination of a relatively high light level and a relatively high temperature included in the second temperature range is the first indication information, and the indication information corresponding to the combination of a relatively low light level and a relatively low temperature included in the second temperature range is the second indication information. The "second" in the second temperature range here is used to distinguish it from the temperature range in the foregoing embodiments.

[0252] This is illustrated by the following examples.

[0253] As shown in Table 6 below, an example of the second information is shown. Among them, the light level includes two levels, YES and NO. The light intensity of the YES level is higher than that of the NO level. For example, 5 can be used as the threshold. If the light intensity is less than 5, the light level is the NO level; otherwise, the light level is the YES level. The second temperature range includes: (0, 30°C], (30°C, 35°C], (35°C, 40°C], (40°C, +

[0254] ∞). The first indication information is Lv1, and the second indication information is Lv0.

[0255] Assume that the ambient temperature is 26°C, which is in the second temperature range (0, 30°C], and the light level is the YES level. Then, the corresponding indication information found from Table 6 is Lv0, which is not the first indication information, so it is determined not to perform temperature compensation on the first temperature value.

[0256] Assume that the ambient temperature is 40°C, which is in the second temperature range (35°C, 40°C], and the light level is YES. Then, the corresponding indication information found from Table 6 is Lv1, which is the first indication information, so it is determined to perform temperature compensation on the first temperature value.

[0257]

[0258] Table 6

[0259] In the second embodiment, the second target parameter may include the light level received by the target dimming glass. Then, determining whether to perform temperature compensation on the first temperature value according to the second target parameter may include:

[0260] Finding the indication information corresponding to the light level received by the target dimming glass from the preset information; the indication information is used to indicate whether to perform temperature compensation on the first temperature value; the preset information records the indication information corresponding to different light levels;

[0261] Determining whether the indication information is the first indication information.

[0262] Among them, the first indication information is used to indicate performing temperature compensation on the first temperature value, and the second indication information is used to indicate not performing temperature compensation on the first temperature value.

[0263] For example, if the light level includes two levels, YES and NO, the preset information may include: the light level YES corresponds to the first indication information, and the light NO corresponds to the second indication information.

[0264] In the third embodiment, the second target parameter may include the ambient temperature of the environment where the target dimming glass is located. Then, determining whether to perform temperature compensation on the first temperature value according to the second target parameter may include:

[0265] Determine the second temperature range in which the ambient temperature of the environment where the target dimming glass is located lies;

[0266] Find the indication information corresponding to the second temperature range from the preset information; the indication information is used to indicate whether to perform temperature compensation on the first temperature value; different indication information corresponding to different second temperature ranges is recorded in the preset information;

[0267] Determine whether the indication information is the first indication information.

[0268] Among them, the first indication information is used to indicate performing temperature compensation on the first temperature value, and the second indication information is used to indicate not performing temperature compensation on the first temperature value.

[0269] In other embodiments, the second target parameter may include: the light level received by the target dimming glass and the driving speed of the vehicle where the target dimming glass is located; or, the second target parameter may include: the ambient temperature of the environment where the target dimming glass is located, the driving speed of the vehicle where the target dimming glass is located; or, the second target parameter may include: the light level received by the target dimming glass, the ambient temperature of the environment where the target dimming glass is located, the driving speed of the vehicle where the target dimming glass is located.

[0270] At this time, the specific implementation of determining whether to perform temperature compensation on the first temperature value according to the second target parameter may refer to the first embodiment, with the main difference being parameter replacement and adaptive adjustment of the preset information. It should be noted that when the parameters in other dimensions are the same, the relationship between the above driving speed and the indication information may be: for the speed range with a relatively small speed, the corresponding indication information may be the first indication information, and for the speed range with a relatively large speed, the corresponding indication information may be the second indication information.

[0271] In another embodiment provided by the present application, after adjusting the target dimming glass to the second gear in step 1005, when the temperature of the target dimming glass is too high and the target dimming glass does not support working in the second gear, the gear of the target dimming glass can be adjusted to a gear that the target dimming glass can support, or when the temperature of the target dimming glass is too high but the target dimming glass supports working in the second gear, the light transmittance of the target dimming glass can be adjusted to further extend the service life of the target dimming glass.

[0272] As ​ shown, after step 1005, the method may further include:

[0273] Step 1201: Obtain a fifth temperature value of the target dimming glass; the fifth temperature value is used to represent the real-time temperature measurement value of the target dimming glass.

[0274] Step 1202: Obtain a second temperature compensation value, and perform temperature compensation on the fifth temperature value according to the second temperature compensation value to obtain a sixth temperature value.

[0275] Step 1203: Determine the third temperature range where the sixth temperature value is located.

[0276] Step 1204: Determine that the third temperature range where the sixth temperature value is located is different from the third temperature range where the second temperature value is located.

[0277] Among them, when it is determined that the third temperature range where the sixth temperature value is located is the same as the third temperature range where the second temperature value is located, the target dimming glass can be kept unchanged in the second gear.

[0278] Step 1205: Determine whether the light transmittance corresponding to the combination of the third temperature range where the sixth temperature value is located and the second gear can be found from the preset third information. If so, execute step 1207; if not, execute step 1206.

[0279] Step 1206: Adjust the gear of the target dimming glass from the second gear to the third gear, and this branch process ends.

[0280] Among them, the third gear is a gear that the target dimming glass can support at the sixth temperature value.

[0281] Step 1207: Find the second light transmittance corresponding to the combination of the third temperature range where the sixth temperature value is located and the second gear from the preset third information, and determine that the second light transmittance is different from the first light transmittance, and adjust the light transmittance of the target dimming glass to the second light transmittance.

[0282] The above-mentioned preset third information may be ​ the control information described in

[0283] In this method, by adjusting the gear position of the target dimming glass from a second gear position that is no longer supported to a third gear position that can be supported, or by adjusting the light transmittance of the target dimming glass from a first light transmittance that is no longer supported to a second light transmittance that can be supported, the lifespan of the target dimming glass can be extended.
