Description

A dimming method, device, system and vehicle TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a dimming method, device, system and vehicle. BACKGROUND

[0002] The intelligent rear row entertainment of a vehicle has become a necessity for consumers to purchase a vehicle. At present, various types of large sport utility vehicles (SUV) and high-end multi-purpose vehicles (MPV) are equipped with displays in the rear row of the vehicle, such as ceiling screens, large televisions and other display screens, and some vehicles are equipped with projection systems in the rear row. The increase of the entertainment attribute equipment puts forward higher and higher requirements on the readability and comfort of the vehicle display. The brightness adjustment is the most basic requirement among the readability requirements.

[0003] At present, the adjustment scheme for the brightness of the display screen includes manual adjustment and automatic adjustment. The manual adjustment needs to be frequently operated by the user, which affects the user experience. The automatic adjustment adjusts the brightness of the display screen based on the ambient light intensity collected by the ambient light sensor integrated on the display screen, so that the brightness of the display screen is suitable for the human eye to watch. However, in some scenarios, the display screen brightness adjusted to the highest still cannot meet the user's viewing needs, especially for the projection system.

[0004] SUMMARY

[0005] The present application provides a dimming method, device, system and vehicle to reduce the situation that the display screen brightness adjusted to the highest still cannot meet the viewing needs.

[0006] In a first aspect, the present application provides a dimming method, comprising:

[0007] obtaining a first ambient light intensity in a current space where an electronic device is located; wherein the electronic device is used to display content, including a projection light machine or including a screen;

[0008] adjusting the ambient light intensity of the current space and / or adjusting the output brightness of the electronic device according to the first ambient light intensity and the output brightness of the electronic device; the ambient light intensity is adjusted by adjusting the ambient light transmittance.

[0009] Based on the above dimming scheme, the present application proposes to adjust the ambient light transmittance to reduce the situation that the electronic device adjusted to the maximum brightness still cannot meet the viewing needs of the human eye. Compared with the scheme of adjusting only the output brightness of the electronic device in the traditional scheme, the dimming scheme combining the ambient light transmittance proposed by the present application can also effectively reduce the power consumption of the electronic device.

[0010] In a possible implementation, the adjusting the ambient light illumination of the current space and / or the output luminance of the electronic device according to the first ambient light illumination and the output luminance of the electronic device specifically comprises:

[0011] When the output luminance of the electronic device is the first luminance value, the ambient light transmittance is adjusted according to the first ambient light illumination.

[0012] In a possible implementation, the method further comprises:

[0013] When the ambient light transmittance is the maximum transmittance or the minimum transmittance, the output luminance of the electronic device is adjusted according to the first ambient light illumination.

[0014] In the above solution, the output luminance of the electronic device is first fixed, so as to reduce the power consumption of the electronic device caused by adjusting the luminance. Based on the fixed luminance, the ambient light transmittance is adjusted according to the ambient light. When the ambient light transmittance cannot be continuously adjusted, for example, when the ambient light transmittance reaches the minimum value or the maximum value, the fixed luminance is cancelled, and the output luminance of the electronic device is adjusted.

[0015] In a possible implementation, the first luminance value is a maximum value of the output luminance of the electronic device.

[0016] In a possible implementation, the adjusting the ambient light transmittance according to the first ambient light illumination specifically comprises:

[0017] The ambient light transmittance is adjusted according to the first ambient light illumination and an illumination threshold value, so that the ambient light illumination in the current space after adjustment is the illumination threshold value; wherein the illumination threshold value is set based on the first luminance value.

[0018] In the above solution, when the display luminance is fixed, the corresponding ambient light illumination is used as the illumination threshold value, and the purpose of adjusting the ambient light transmittance is to make the ambient light illumination of the space reach the illumination threshold value.

[0019] In a possible implementation, the method further comprises:

[0022] In a possible implementation, the method further comprises:

[0023] When the first temperature is greater than a first temperature threshold value, the ambient light illumination of the current space and the output luminance of the electronic device are adjusted.

[0024] In the above scheme, a dimming scheme based on the temperature of the electronic device is proposed. When the temperature of the electronic device is high, it indicates that the power consumption of the electronic device is high. At this time, if the high output brightness is maintained, the power consumption will further increase. Therefore, in the above scheme, when the temperature of the electronic device is high, the output brightness of the electronic device and the ambient light transmittance are adjusted simultaneously.

[0065] The schemes provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0066] The following explains some terms in the embodiments of the present application. It should be noted that these explanations are for the convenience of understanding by those skilled in the art, and do not constitute a limitation on the scope of protection required by the embodiments of the present application.

[0067] 1. Ambient light sensor: The ambient light sensor is used to perceive the surrounding light conditions and is mainly composed of a photosensitive element, which can be, for example, a photoresistor, a photodiode, a phototriode, etc.

[0068] 2. Liquid crystal glass: It can also be called electrically controlled liquid crystal glass, electrically controlled dimming glass, LC glass, or dimming glass, etc. Its core material is a liquid crystal film. The liquid crystal glass encapsulates the liquid crystal film through a sandwich layer and uses the passage of current to control the arrangement of liquid crystal molecules, thereby changing the transparent and opaque states of the glass.

[0069] 3. Local Interconnect Network (LIN) bus: The LIN bus is a low-cost serial communication bus based on a universal asynchronous receiver / transmitter (UART) or serial communication interface (SCI), which applies the concept of single master and multiple slaves, and is mainly used to build a simple and low-cost local network. Generally, a LIN network can connect up to 16 nodes, the maximum bus length is 40 meters, and the maximum transmission rate is limited to 20 kbps. In the field of vehicle, the LIN bus is usually applied in the body system, and is used in the fields related to comfort such as windows, seats, sunroofs, door locks, air conditioners, lighting, etc. For example, the domain controller in the vehicle and the motor of the window are connected through the LIN bus.

[0070] The foregoing introduces some terms related to the embodiments of the present application, and the following introduces possible application scenarios of the embodiments of the present application.

[0071] In a possible implementation, the dimming scheme provided by the embodiments of the present application can be applied to an electronic device, or applied to any controller of a space where the electronic device is located, wherein the electronic device can be installed in a vehicle, and the vehicle can include, but is not limited to, a vehicle, a ship, an airplane, a fighter, a train, a subway, a high-speed rail, an automated guided vehicle (AGV), etc.

[0072] FIG. 1 shows a possible application scenario provided by the embodiments of the present application, which takes the electronic device installed in a vehicle as an example. In one example, as shown in FIG. 1, the electronic device 101 (or the electronic device 102) is installed in front of the passengers in the rear row of the vehicle, for providing in-vehicle entertainment. It should be noted that the electronic device 101 shown in FIG. 1 is only an example, and the electronic device can also be a projection system including a projection light machine and a projection screen, and the specific implementation form of the electronic device is not limited in the present application. In addition, as shown in FIG. 1, other electronic devices can also be arranged in the vehicle, such as the electronic device 103 at the center console of the vehicle and the electronic device 104 in front of the co-pilot passenger. In addition, as shown in FIG. 1, a camera 105 can also be arranged in the vehicle. It should be noted that multiple cameras can be arranged in the vehicle, and the positions of the multiple cameras are flexible. For example, the camera can be arranged above the electronic device 103 in the vehicle, or can also be arranged at the top front of the vehicle cabin. The camera 105 shown in FIG. 1 is only a possible example.

[0073] In addition, the electronic device of the vehicle can also support intelligent control, including but not limited to voice control, touch control, application (APP) control, gesture control, etc. For example, the user in the vehicle can issue a voice instruction such as "increase brightness", "decrease brightness", "increase volume", etc., the vehicle-mounted microphone collects the corresponding voice content and sends it to the cabin domain controller or the controller integrated in the electronic device, and the cabin domain controller or the controller integrated in the electronic device adjusts the content output by the electronic device according to the voice content. For another example, the user in the vehicle can click the control on the display screen of the electronic device to enter the interface for adjusting the content output by the electronic device, so as to manually adjust the content output by the electronic device. For another example, the user can send a control message of the electronic device through the vehicle-mounted control APP of the mobile phone, and the control message can be verified by the cloud and sent to the vehicle end to control the content output by the electronic device, etc. There are many possible intelligent control methods, which are not listed one by one here.

[0074] It should be understood that the above vehicle can be any type of vehicle, including but not limited to a pure electric vehicle (pure EV / battery EV), a hybrid electric vehicle (HEV), a range extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), other new energy vehicles (NEVs), or a fuel vehicle, etc.

[0075] In addition, the above application scenarios are only examples, and the dimming scheme provided by the embodiments of the present application can also be applied to other possible scenarios, and is not limited to the above examples. In addition, the application scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application.

[0076] As described in the background, the existing dimming schemes mainly include manual dimming and automatic dimming. In the manual dimming mode, the electronic device provides a control for adjusting the brightness of the display screen, and the brightness of the display screen is adjusted in response to the operation of the user on the control. For example, the control is a brightness adjustment bar, and the electronic device adjusts the brightness of the display screen in response to the operation of the user dragging the brightness adjustment bar. Although the manual adjustment scheme does not need to increase the cost of additional hardware, it needs the user to frequently adjust the brightness of the display screen manually, resulting in poor user experience.

[0077] In the automatic dimming mode, the display screen integrates an ambient light sensor, which can collect the ambient light intensity near the display screen and feed back to the electronic device. The electronic device combines the built-in dimming algorithm to realize the automatic adjustment of the display screen brightness. The automatic dimming scheme is mature in technology and is currently widely used in liquid crystal displays (LCD) and organic light-emitting diodes (OLED). However, when it is applied to in-vehicle dimming, at least two problems exist.

[0078] Problem one: the logic of the automatic dimming mode is relatively simple. When the environment becomes brighter, the display becomes brighter, which will cause the electronic device to increase in temperature, increase in power consumption, and reduce in service life.

[0079] Problem two: in the vehicle environment, the ambient light is generally bright, and the display screen brightness cannot be adjusted to match the ambient light intensity even when the automatic dimming mode is used. Especially for projection-type electronic devices, the size of the screen, the reliability of the light source, and factors such as noise, vibration, harshness (NVH) will affect the output brightness of the projector. Even if the output brightness of the projector is adjusted to the highest level, the screen still cannot meet the user's viewing needs. As an example, see FIG. 2, which shows the effect of ambient light on the display content of the screen. The shaded part in the lower left corner of the screen shown in FIG. 2 is the part that is blurred and unclear due to light.

[0080] Based on this, the present application proposes a dimming scheme that not only makes the display content of the display screen clearer and the user's visual experience higher, but also effectively reduces the power consumption of the electronic device.

[0081] The dimming scheme proposed by the present application will be described in detail below with reference to the accompanying drawings. By way of example, see FIG. 3, which is a flowchart of a dimming method provided by an embodiment of the present application. Optionally, the dimming scheme shown in FIG. 3 can be executed by an electronic device, such as the electronic device 101 or the electronic device 102 in the scenario shown in FIG. 1. Alternatively, the dimming scheme shown in FIG. 3 can be executed by a processor or processing chip in the electronic device 101 or the electronic device 102. Alternatively, the dimming scheme shown in FIG. 3 can be executed by any controller in the space where the electronic device is located, such as any one of the domain controllers in the vehicle shown in FIG. 1, for example, the cabin domain controller. The present application does not limit the execution subject of the method flow shown in FIG. 3, which will be described below taking the cabin domain controller as an example. The method flow shown in FIG. 3 specifically includes:

[0082] In step 301, the cabin domain controller acquires the first ambient light intensity in the current space where the electronic device is located.

[0083] The electronic device can be used to display content, and can also be referred to as a display device. The electronic device can include a projection light machine or a display screen. For example, the electronic device can be the electronic device 101 or the electronic device 102 in the vehicle shown in FIG. 1, or other devices capable of displaying content.

[0084] For example, the current space can include at least one light sensing element for collecting ambient light data in the current space. The cabin domain controller can obtain a first ambient light intensity according to the ambient light data collected by the at least one light sensing element. Since the first ambient light intensity is used to adjust the light in the current space, so that the brightness of the display screen of the electronic device can be suitable for the human eye to watch, the present application proposes that the at least one light sensing element can be deployed near the electronic device, so as to accurately represent the light near the electronic device. Alternatively, the at least one light sensing element can be deployed near the light transmission hole of the current space, so as to accurately represent the light entering the current space.

[0085] For example, taking the vehicle shown in FIG. 1 as an example, the at least one light sensing element included in the vehicle can be a light sensing element integrated in the electronic device 101 or the electronic device 102, or can be a light sensing element deployed near the electronic device 101 and the electronic device 102, such as a position behind the front seats of the vehicle. Alternatively, the at least one light sensing element can also be deployed near the vehicle window. Of course, the light sensing element can be deployed near the vehicle window, near the electronic device 101 and the electronic device 102, and the number and position of the light sensing element deployed in the current space are not limited in the present application.

[0086] In one possible implementation, the light sensing element in the current space can be an independent ambient light sensor, which can be deployed near the electronic device and the light transmission hole of the space as described above, or integrated in the electronic device and the light transmission hole. In addition, the light sensing element can also be a sensor for collecting light built in the camera in the current space (for the sake of description, the sensor built in the camera is also referred to as an ambient light sensor). For example, taking the vehicle shown in FIG. 1 as an example, the at least one light sensing element included in the vehicle can include an ambient light sensor built in the camera 105 inside the vehicle.

[0087] Exemplarily, when the method flow shown in FIG. 3 is executed by the cabin domain controller, the at least one light sensing element transmits the real-time collected ambient light data to the cabin domain controller, for example, the ambient light data can be transmitted through a LIN bus. The cabin domain controller determines the first ambient illuminance according to the ambient light data collected by the at least one light sensing element. For example, the cabin domain controller can take the average value of the ambient light data collected by the at least one light sensing element as the first ambient illuminance. For another example, when there are two or more light sensing elements, the cabin domain controller can previously set different weights for the light sensing elements deployed at different positions, and further, the ambient light data transmitted by each light sensing element is weighted and averaged to obtain the first ambient illuminance. For another example, different weights can also be previously set for different light sensing elements according to different collection accuracies corresponding to different light sensing elements, and further, the ambient light data transmitted by each light sensing element is weighted and averaged to obtain the first ambient illuminance. It should be noted that the above-mentioned manner is only exemplary, and the present application does not limit the specific implementation manner of obtaining the first ambient illuminance by using the ambient light data collected by the at least one light sensing element.

[0088] In step 302, the cabin domain controller adjusts the ambient illuminance of the current space and / or adjusts the output brightness of the electronic device according to the first ambient illuminance and the output brightness of the electronic device.

[0089] The ambient illuminance of the current space is achieved by adjusting the ambient light transmittance, that is, by adjusting the ambient light entering the current space. The cabin domain controller adjusts the light according to the first ambient illuminance and the output brightness of the electronic device, which can include the following three cases:

[0090] Case one: the cabin domain controller adjusts the ambient light transmittance in combination with the first ambient illuminance and the output brightness of the electronic device.

[0091] Exemplarily, when adjusting, the cabin domain controller can first obtain the mapping relationship between the ambient illuminance and the output brightness of the electronic device, which can be obtained by experiment in advance, and describes the output brightness of the electronic device that is most suitable for the human eye to watch under different ambient illuminances. The mapping relationship can be pre-stored in various forms such as a curve graph, a table, a sequence, etc. As an example, FIG. 4 is a schematic diagram of a curve graph form of the mapping relationship provided by an embodiment of the present application. It should be noted that FIG. 4 is only exemplary and does not limit the actual mapping relationship.

[0092] Further, the cabin domain controller determines, according to the mapping relationship, that the output brightness of the electronic device corresponds to the second ambient illuminance, and determines that the second ambient illuminance is not the same as the first ambient illuminance. (It should be noted that if the output brightness of the electronic device determined according to the mapping relationship corresponds to the second ambient illuminance which is the same as the first ambient illuminance, it means that the brightness of the current display screen or projection screen can meet the viewing needs of the human eye, and there is no need to perform dimming processing, so this case is not embodied in FIG. 3.)

[0093] Still further, the cabin domain controller adjusts the environmental light transmittance according to the difference between the first ambient illuminance and the second ambient illuminance. In an example, after adjusting the environmental light transmittance, the ambient illuminance in the current space can be exactly the second ambient illuminance, thereby meeting the viewing needs of the human eye. In order to make the adjusted ambient illuminance exactly equal to the second ambient illuminance, a high adjustment precision can be set during the adjustment process. The adjustment precision can also be referred to as an adjustment step or an adjustment amplitude, which represents the value of the environmental light transmittance adjusted each time during the adjustment process. For example, the adjustment process will be performed multiple times, and the adjustment precision is 0.1%. This means that the cabin domain controller will adjust the environmental light transmittance by 0.1% each time, and after each adjustment, the ambient illuminance will be obtained again to determine whether it is equal to the second ambient illuminance. If it is equal, the adjustment process ends; if it is not equal, the cabin domain controller continues to adjust according to the adjustment precision of 0.1%, until the ambient illuminance in the current space reaches the second ambient illuminance.

[0094] Of course, higher adjustment accuracy will make the adjustment process take longer, and increase the processor resources and transmission resources occupied. For example, taking the scenario shown in FIG. 1 as an example, the adjustment is performed by the cabin domain controller, and the cabin domain controller will issue adjustment instructions to the motor of the vehicle window multiple times through the LIN bus according to the adjustment accuracy. This process will occupy a lot of LIN bus resources. And the higher the adjustment accuracy, the more times the cabin domain controller will execute the judgment that the ambient illuminance reaches the second ambient illuminance and the more times it will issue adjustment instructions, and the more resources the cabin domain controller will occupy. Based on this, in another example, a lower adjustment accuracy can be set, and the adjusted ambient illuminance can be lower or higher than the second ambient illuminance. In this case, after adjusting the ambient light transmittance, the matching degree of the output brightness of the electronic device and the viewing needs of the human eye will be higher, but it cannot fully meet the viewing needs of the human eye. Therefore, after adjusting the ambient light transmittance, the cabin domain controller can further adjust the output brightness of the electronic device. For example, the cabin domain controller can obtain a third ambient illuminance of the current space after adjusting the transmittance, determine the output brightness corresponding to the third ambient illuminance based on the mapping relationship between the ambient illuminance and the output brightness of the electronic device, and adjust the output brightness of the electronic device using the output brightness. Or, the cabin domain controller can not adjust the output brightness of the electronic device after adjusting the ambient light transmittance, in order to save the processing resources and transmission resources of the device.

[0095] Exemplarily, the current space can include one or more light-transmitting holes, and adjusting the ambient light transmittance can be adjusting the light transmittance of the one or more light-transmitting holes. In a possible implementation manner, taking the vehicle shown in FIG. 1 as an example, the one or more light-transmitting holes can be the vehicle windows, for example, can include side window glass, sunroof glass, or rear windshield glass of the vehicle, etc. Adjusting the ambient light transmittance is to adjust the ambient light entering the current space through the multiple vehicle windows.

[0096] In another possible implementation, the target light-transmitting hole can also be selected from the one or more light-transmitting holes, and adjusting the ambient light transmittance is to adjust the ambient light entering the current space through the target light-transmitting hole. For example, the target light-transmitting hole can be determined according to the position of the user and the position of the electronic device, for example, a light-transmitting hole close to the user or close to the electronic device can be selected as the target light-transmitting hole. Alternatively, the target light-transmitting hole can also be determined according to the direction of the light entering, for example, a light-transmitting hole in the direction in which the light enters in the largest amount can be selected as the target light-transmitting hole. Specifically, a light-sensing element can be arranged near each light-transmitting hole. Further, the cabin domain controller selects the target light-transmitting hole from the ambient light data collected by the light-sensing element near each light-transmitting hole. The ambient light data collected by the light-sensing element near the target light-transmitting hole is greater than the ambient light data collected by the light-sensing element near other light-transmitting holes. For example, as shown in FIG. 1, the light-transmitting hole is a window of the vehicle, when the light enters from the left side of the vehicle, the ambient light data collected by the light-sensing element near the left window is greater than the ambient light data collected by the light-sensing element near other windows (the right window, the sunroof, or the rear windshield), and the cabin domain controller determines that the left window is the target light-transmitting hole and adjusts the light transmittance of the left window.

[0097] In another possible implementation, when there are two or more light-transmitting holes, different adjustment weights can also be set for light-transmitting holes in different positions, and the cabin domain controller can adjust the light-transmitting holes in different positions to different degrees based on the weights when adjusting the ambient light transmittance. For example, the weight can be set according to the distance between the light-transmitting hole and the user or the distance between the light-transmitting hole and the electronic device, and a light-transmitting hole close to the user or a light-transmitting hole close to the electronic device can be set to a higher weight. For another example, the weight can also be set based on the direction of the light entering, for example, a light-transmitting hole in which the light enters in a larger amount can be set to a higher weight, and a light-transmitting hole in which the light enters in a smaller amount can be set to a lower weight. The amount of light entering each light-transmitting hole can be determined according to the ambient light data collected by the light-sensing element arranged near each light-transmitting hole.

[0098] In adjusting the ambient light entering the current space through the one or more light-transmitting holes, the cabin domain controller can adjust the light transmittance of the one or more light-transmitting holes to achieve. In an example, the one or more light-transmitting holes can be covered by liquid crystal glass, and then the cabin domain controller can control the light transmittance of the liquid crystal film in the liquid crystal glass through the motor at the one or more light-transmitting holes, so as to realize the adjustment of the light transmittance of the one or more light-transmitting holes. For example, taking the vehicle shown in FIG. 1 as the current space where the electronic device is located, the one or more light-transmitting holes are the windows of the vehicle, and the window glass is the liquid crystal glass, and the light transmittance of the window glass can be adjusted by the motor at each window. In another example, each of the one or more light-transmitting holes can be provided with a sunshade curtain (or other light shielding device, which is taken as the sunshade curtain for example here), and then the cabin domain controller can adjust the opening degree of the sunshade curtain of the one or more light-transmitting holes to realize the adjustment of the light transmittance of the one or more light-transmitting holes.

[0099] Case two: The cabin domain controller adjusts the output brightness of the electronic device in combination with the first ambient illuminance and the output brightness of the electronic device.

[0100] For the convenience of introducing case two, the obtained current output brightness of the electronic device is referred to as the first output brightness.

[0101] Exemplarily, in the process of adjusting, the cabin domain controller can first obtain the mapping relationship between the output brightness of the electronic device and the ambient illuminance. The introduction of the mapping relationship can be referred to in case one described above, and will not be described here. Further, the cabin domain controller determines the second output brightness of the electronic device corresponding to the first ambient illuminance according to the mapping relationship. Wherein, the first output brightness and the second output brightness are not the same. (It should be noted that if the first output brightness and the second output brightness are the same, it means that the display screen of the electronic device can meet the viewing needs of the human eye under the first ambient illuminance, and there is no need to adjust the light. Therefore, this case is not embodied in FIG. 3.)

[0102] Further, the cabin domain controller adjusts the output brightness of the electronic device from the first output brightness to a second output brightness. For example, taking the vehicle shown in FIG. 1 as the current space where the electronic device is located, when the dimming scheme shown in FIG. 3 is executed by the cabin domain controller of the vehicle, the cabin domain controller can send an adjustment instruction to the electronic device through the LIN bus, which is used to instruct the electronic device to adjust the output brightness to the second output brightness. After receiving the adjustment instruction, the electronic device adjusts the output brightness. Alternatively, when the dimming scheme shown in FIG. 3 is executed by the electronic device (for example, can include being executed by a processor or processing chip in the electronic device), the electronic device can directly adjust its own output brightness to the second output brightness after determining the second output brightness. For example, when the electronic device includes a display screen, the cabin domain controller can adjust the backlight of the display screen to make the brightness of the display screen reach the second output brightness. For another example, when the electronic device is a projection system including a projection light machine and a projection screen, the cabin domain controller can adjust the output brightness of the projection light machine to the second output brightness.

[0103] As an optional way, the cabin domain controller can also adjust in combination with the temperature of the electronic device during the dimming process. If the collected temperature of the electronic device is greater than the first temperature threshold, and the output brightness of the electronic device needs to be increased (for example, the first output brightness is lower than the second output brightness) based on the ambient illuminance, then the dimming method provided in case two cannot be used. Because the high temperature of the electronic device indicates that the current power consumption of the electronic device is high, if the output brightness is further increased in this case, the power consumption of the electronic device will be further increased, which will reduce the service life of the electronic device. Therefore, in this case, the ambient light transmittance needs to be adjusted. As an example, in this case, the ambient light transmittance can be reduced, so that the ambient illuminance in the current space can match the current output brightness of the electronic device, so that the output brightness of the electronic device does not need to be adjusted. The specific adjustment process can be referred to in case one described above. As another example, in this case, the ambient light transmittance and the output brightness of the electronic device can also be adjusted at the same time, the ambient light transmittance is reduced, and the output brightness of the electronic device is reduced, so as to reduce the power consumption of the electronic device. The specific adjustment process can be referred to in case three described below.

[0104] Case three: The cabin domain controller adjusts the output brightness of the electronic device and the ambient light transmittance in combination with the first ambient illuminance and the output brightness of the electronic device.

[0105] For ease of description, the current output brightness of the electronic device obtained in case three is still referred to as the first output brightness.

[0106] Exemplarily, when the adjustment is performed, the cabin domain controller can first acquire a mapping relationship between the ambient illuminance and the output brightness of the electronic device, and the description about the mapping relationship can be referred to the description in the case one above, which will not be repeated here. Further, the cabin domain controller can determine, according to the mapping relationship, that the second output brightness of the electronic device corresponding to the first ambient illuminance is different from the first output brightness, or the cabin domain controller can also determine, according to the mapping relationship, that the second ambient illuminance corresponding to the first output brightness of the electronic device is different from the first ambient illuminance.

[0107] Further, the cabin domain controller can adjust the output brightness of the electronic device and the ambient light transmittance simultaneously in combination with the first ambient illuminance and the first output brightness, so that the adjusted output brightness meets the viewing requirement of the human eye under the ambient illuminance after the adjustment of the ambient light transmittance. For example, after the adjustment of the ambient light transmittance, the ambient illuminance of the current space is a fourth ambient illuminance. At the same time, after the adjustment of the output brightness of the electronic device, the output brightness of the electronic device is a third output brightness. In the mapping relationship between the ambient illuminance and the output brightness of the electronic device, the ambient illuminance corresponding to the third output brightness is the fourth ambient illuminance.

[0108] Based on the above light adjustment scheme, the present application proposes to adjust the ambient light transmittance to reduce the situation that the electronic device is adjusted to the maximum brightness but still cannot meet the viewing requirement of the human eye. Moreover, compared with the scheme of adjusting only the output brightness of the electronic device in the traditional scheme, the light adjustment scheme combining the ambient light transmittance proposed by the present application can also effectively reduce the power consumption of the electronic device.

[0109] As described in the case three in the step 302 above, when the cabin domain controller adjusts the ambient light transmittance and the output brightness of the electronic device simultaneously, a fixed ambient light transmittance can be set to adjust the output brightness of the electronic device, or a fixed output brightness of the electronic device can be set to adjust the ambient light transmittance. Next, the mode one to mode two will be introduced:

[0110] Mode one: fixed ambient light transmittance.

[0111] Exemplarily, as described in the third case above, when adjusting the output brightness of the electronic device and the ambient light transmittance, the cabin domain controller can first adjust the ambient light transmittance to a fixed light transmittance. Optionally, the fixed light transmittance can be pre-set by the user. As described in the first case above, adjusting the ambient light transmittance can be achieved by adjusting the light transmittance of one or more light transmittance holes in the current space, and then adjusting the ambient light transmittance to the fixed light transmittance can be adjusting the light transmittance of all the light transmittance holes to the fixed light transmittance. Alternatively, a target light transmittance hole can be selected from the one or more light transmittance holes, and the light transmittance of the target light transmittance hole is adjusted to the fixed light transmittance. Alternatively, when there are two or more light transmittance holes, the light transmittance holes can be assigned weights according to their positions, and the light transmittance of the light transmittance hole with the highest weight or the light transmittance hole with a weight exceeding a set threshold can be adjusted to the fixed light transmittance. Of course, the way of adjusting the ambient light transmittance to the fixed light transmittance is not limited to the above, and the above is only an example.

[0112] Further, after adjusting the ambient light transmittance to the fixed light transmittance, the cabin domain controller obtains a fifth ambient illuminance of the current space. Further, the cabin domain controller determines the output brightness corresponding to the fifth ambient illuminance according to the mapping relationship between the ambient illuminance and the output brightness of the electronic device, and adjusts the output brightness of the electronic device to the output brightness.

[0113] In an example, the fixed ambient light transmittance can be the minimum light transmittance that can be achieved in the current space. For example, taking the vehicle shown in FIG. 1 as the current space where the electronic device is located, the ambient light transmittance in the vehicle can be set to the minimum light transmittance, which can be adjusting the transmittance of all the glass in the vehicle except the front windshield to the minimum transmittance. Alternatively, a target vehicle window glass can be selected from the multiple vehicle window glasses in the vehicle, and the transmittance of the target vehicle window glass is adjusted to the minimum transmittance. Alternatively, different weights can be assigned to different vehicle window glasses according to their positions, and the vehicle window glass with the maximum weight or the weight exceeding a set threshold is adjusted to the minimum transmittance.

[0114] When the vehicle window glass is a liquid crystal glass, adjusting the transmittance of the vehicle window glass to the minimum transmittance can be achieved by controlling the arrangement of liquid crystal molecules through the vehicle window motor, so that the light transmittance reaches the minimum. Alternatively, the opening of the sunshade curtain of the vehicle window glass can be adjusted to zero to achieve the adjustment of the transmittance of the vehicle window glass to the minimum transmittance. For example, the sunshade curtain of the vehicle window glass can be fully raised.

[0115] Based on the above scheme, after the environmental light transmittance is adjusted to the minimum light transmittance, the output brightness of the electronic device is adjusted according to the ambient light intensity in the space to meet the viewing requirements of the human eye. Since the environmental transmittance is minimum, the vehicle interior environment is relatively dark, and the brightness of the electronic device required by the user is also low, thereby effectively reducing the power consumption of the electronic device.

[0116] Exemplarily, before adjusting the environmental light transmittance to the minimum light transmittance, the cabin domain controller can first obtain the temperature of the electronic device. In the case that the temperature of the electronic device is relatively high, such as higher than the first temperature threshold, the environmental light transmittance is adjusted to the minimum light transmittance, and then the output brightness of the electronic device is adjusted based on the ambient light intensity of the adjusted current space.

[0117] Method two: fixing the output brightness of the electronic device.

[0118] Exemplarily, as described in the above case three, when adjusting the output brightness of the electronic device and the environmental light transmittance, the cabin domain controller can set the output brightness of the electronic device to a fixed brightness value. Optionally, the fixed brightness value can be a brightness value set by the user in advance. After setting the output brightness of the electronic device to the fixed brightness value, the cabin domain controller can adjust the environmental light transmittance according to the ambient light intensity in the current space. For ease of description, the ambient light intensity in the current space is referred to as the first ambient light intensity.

[0119] Exemplarily, when performing the adjustment, the cabin domain controller can first obtain the mapping relationship between the output brightness of the electronic device and the ambient light intensity, and determine the sixth ambient light intensity corresponding to the fixed brightness value according to the mapping relationship. Further, the cabin domain controller adjusts the environmental light transmittance according to the difference between the first ambient light intensity and the sixth ambient light intensity, so that the ambient light intensity in the adjusted current space reaches the sixth ambient light intensity. For example, when the sixth ambient light intensity is higher than the first ambient light intensity, the cabin domain controller can increase the environmental light transmittance; when the sixth ambient light intensity is lower than the first ambient light intensity, the cabin domain controller can decrease the environmental light transmittance. The specific process of adjusting the environmental light transmittance can be referred to the case one in the above step 302, which will not be described here in detail.

[0120] In a case, the ambient light transmittance is adjusted to the maximum or minimum, and the sixth ambient illuminance still cannot be reached. For example, the sixth ambient illuminance is lower than the first ambient illuminance, the ambient light transmittance is gradually adjusted to the minimum according to the adjustment precision, and the ambient illuminance of the current space is still higher than the sixth ambient illuminance. In this case, the cabin domain controller can cancel the fixed brightness value, and adjust the output brightness of the electronic device based on the ambient illuminance of the current space after adjusting the ambient light transmittance. The adjustment to the minimum light transmittance can refer to the related description in the above-mentioned manner one, and will not be described in detail here. For another example, the sixth ambient illuminance is higher than the first ambient illuminance, the ambient light transmittance is gradually adjusted to the maximum according to the adjustment precision, and the ambient illuminance of the current space is still lower than the sixth ambient illuminance. In this case, the cabin domain controller can cancel the fixed brightness value, and adjust the output brightness of the electronic device based on the ambient illuminance of the current space after adjusting the ambient light transmittance.

[0121] In a possible implementation, the fixed brightness value introduced above can be the maximum brightness value of the output brightness of the electronic device. In the adjustment process, the cabin domain controller can first determine a seventh ambient illuminance corresponding to the maximum brightness value according to the mapping relationship between the output brightness of the electronic device and the ambient illuminance. When the first ambient illuminance is lower than the seventh ambient illuminance, it indicates that the output brightness of the electronic device has not reached the maximum brightness value, and the cabin domain controller can adjust the output brightness of the electronic device according to the first ambient illuminance, for example, the adjustment process can refer to the adjustment process introduced in the above-mentioned case two. When the first ambient illuminance is higher than the seventh ambient illuminance, it indicates that the output brightness of the electronic device has reached the maximum brightness value, and the cabin domain controller can adjust the ambient light transmittance according to the first ambient illuminance, for example, the adjustment process can refer to the adjustment process introduced in the above-mentioned case one. Optionally, after adjusting the ambient light transmittance, if the ambient illuminance collected afterwards becomes lower, the output brightness of the electronic device can be first adjusted to reduce the power consumption of the electronic device.

[0122] The above introduces the dimming scheme proposed in this application. In order to further understand the scheme, the following will be introduced in combination with specific embodiments. First, the system architecture applied by the scheme is introduced. Exemplarily, FIG. 5 is a schematic diagram of the architecture of a dimming system provided in an embodiment of this application, which includes a light sensing element, a temperature sensor, a controller, a light transmission hole and an electronic device. Exemplarily, taking the system architecture shown in FIG. 5 applied in the vehicle shown in FIG. 1 as an example, the light sensing element in FIG. 5 can be an ambient light sensor deployed near the electronic device 101 (or the electronic device 102) in FIG. 1, or can also be an ambient light sensor built in the camera 105 in FIG. 1. Exemplarily, the light sensing element in FIG. 5 can also include the ambient light sensor deployed near the light transmission hole introduced in the above embodiments. The temperature sensor included in FIG. 5 is used to collect temperature data of the electronic device and report the temperature data to the controller for the controller to perform dimming. Exemplarily, in order to better collect the temperature, the temperature sensor can be integrated in the electronic device or can be deployed near the electronic device. The controller in FIG. 5 can be the cabin domain controller in the vehicle shown in FIG. 1, or can also be other domain controllers in the vehicle, which is not limited in this application. The light transmission hole in FIG. 5 can be the vehicle window glass in the vehicle shown in FIG. 1, which can include side window glass, sunroof glass and rear windshield glass, etc. The electronic device shown in FIG. 5 can be the electronic device 101 or the electronic device 102 in FIG. 1. It should be noted that the architecture shown in FIG. 5 is only an example, and the application scenario of the architecture shown in FIG. 5 and the number of components included in the architecture are not limited.

[0123] The dimming scheme of this application will be further introduced in combination with the architecture of the dimming system shown in FIG. 5. Exemplarily, the dimming scheme of this application can include the following four modes:

[0124] Mode one: can also be called standard mode.

[0125] In mode one, the controller can first determine the seventh ambient light illuminance corresponding to the maximum brightness value of the output brightness of the electronic device according to the mapping relationship between the output brightness of the electronic device and the ambient light illuminance. Further, the controller performs dimming based on the seventh ambient light illuminance. In order to facilitate description, in mode one, the ambient light illuminance of the current space is called the first ambient light illuminance.

[0126] Exemplarily, when performing dimming, the controller can first obtain the collected ambient light data from the light sensing element, and obtain the first ambient light illuminance according to the obtained ambient light data. Exemplarily, the process of the controller obtaining the first ambient light illuminance can refer to the introduction in step 301 above, which will not be described here.

[0127] In a possible case, the first ambient light illuminance is not greater than the seventh ambient light illuminance, in which case, the controller can determine the output luminance of the electronic device corresponding to the first ambient light illuminance according to a mapping relationship between the output luminance of the electronic device and the ambient light illuminance. Further, the controller can send an adjustment instruction carrying the determined output luminance to the electronic device, to instruct the electronic device to adjust the output luminance according to the adjustment instruction.

[0128] In another possible case, the first ambient light illuminance is greater than the seventh ambient light illuminance, indicating that adjusting the luminance of the electronic device to the highest still cannot meet the viewing requirements of the human eye. In this case, the controller can lower the light transmittance of the light transmission hole to reduce the ambient light illuminance to the seventh ambient light illuminance. The specific process of adjusting the light transmittance can be referred to the description in the above case one, which will not be described here in detail. Optionally, after the light transmittance of the light transmission hole is lowered, if the ambient light illuminance subsequently collected continues to increase, the light transmittance of the light transmission hole is continuously lowered; otherwise, if the ambient light illuminance subsequently collected decreases, the output luminance of the electronic device can be lowered preferentially to reduce the power consumption of the electronic device.

[0129] Mode two: which can also be referred to as a custom mode.

[0130] In mode two, the controller sets the output luminance of the electronic device to a fixed luminance value, and adjusts the ambient light transmittance based on the change of the ambient light illuminance. For ease of description, in mode two, the ambient light illuminance of the current space is still referred to as the first ambient light illuminance. Exemplarily, the controller can first obtain a mapping relationship between the output luminance of the electronic device and the ambient light illuminance, and determine a sixth ambient light illuminance corresponding to the fixed luminance value according to the mapping relationship.

[0131] In a possible case, the sixth ambient light illuminance is higher than the first ambient light illuminance, the controller can adjust the ambient light transmittance to increase the ambient light illuminance of the current space from the first ambient light illuminance to the sixth ambient light illuminance according to the difference between the sixth ambient light illuminance and the first ambient light illuminance. The specific process of adjusting the ambient light transmittance can be referred to the case one in the above step 302, which will not be described here in detail. Optionally, during the adjustment process, if the ambient light transmittance is adjusted to the maximum light transmittance and the ambient light illuminance still cannot be increased to the sixth ambient light illuminance, the controller can cancel the fixed luminance value and adjust the output luminance of the electronic device according to the sixth ambient light illuminance.

[0132] In another possible case, the sixth ambient illuminance is lower than the first ambient illuminance, and the controller can lower the ambient light transmittance according to a difference between the sixth ambient illuminance and the first ambient illuminance, so as to reduce the ambient illuminance of the current space from the first ambient illuminance to the sixth ambient illuminance. The process of adjusting the ambient light transmittance can be referred to the case one in step 302, which will not be described herein again. Alternatively, during the adjustment, if the ambient light transmittance is adjusted to the minimum light transmittance and the ambient illuminance still cannot be reduced to the sixth ambient illuminance, the controller can cancel the fixed brightness value and adjust the output brightness of the electronic device according to the sixth ambient illuminance.

[0133] Alternatively, after the fixed brightness value of the electronic device is cancelled, the controller can use the light adjustment scheme in mode one when adjusting the light according to the ambient illuminance collected subsequently.

[0134] Mode three: which can also be referred to as energy-saving mode.

[0135] In mode three, the ambient light transmittance is set to the minimum light transmittance, and the specific setting process can be referred to the description of mode one, which will not be described herein again.

[0136] During the light adjustment, the controller can adjust the output brightness of the electronic device according to the mapping relationship between the output brightness of the electronic device and the ambient illuminance, and the ambient illuminance of the current space. The specific adjustment process can be referred to the case two.

[0137] Mode four: which can also be referred to as temperature control mode.

[0138] During the light adjustment, the controller can also acquire the temperature of the electronic device collected by the temperature sensor, and when the temperature of the electronic device is higher than the first temperature threshold, the controller can adjust the output brightness of the electronic device and the ambient light transmittance simultaneously. For example, the output brightness and the ambient light transmittance can be reduced simultaneously, so as to reduce the temperature of the electronic device. Alternatively, the light adjustment scheme in the case three can also be used.

[0139] The four modes introduced above are modes one to four. It should be noted that the light adjustment mode proposed in the present application is not limited to the four modes. When performing light adjustment, the controller can select any one of the four modes to perform light adjustment, or can perform light adjustment in response to user operation. For example, the controller can determine the light adjustment mode in response to user operation on a display interface for selecting a light adjustment mode. The display interface can be provided by any electronic device in the space that can display content. For example, in the scenario shown in FIG. 1, the display interface can be provided by any one of the electronic devices 101, 102, 103, and 104. As an example, refer to FIG. 6, which shows a display interface for selecting a light adjustment mode according to an embodiment of the present application. The display interface includes a control for each light adjustment mode, and the controller can determine the light adjustment mode selected by the user in response to user operation on the control. The user operation on the control includes, but is not limited to, voice control, touch control, APP control, and gesture control. It should be noted that the display interface shown in FIG. 6 is only an example and does not limit the content of the display interface for selecting a light adjustment mode.
