Description

Technical Field

[0001] This application relates to the field of dimming awning technology, and in particular to a dimming awning control method, device and vehicle that are linked with vehicle ambient lighting. Background Technology

[0002] In recent years, vehicles have gradually become an important part of people's work and life as a means of transportation or mobility. With the development and advancement of technology, people have higher demands for the comfort, aesthetics, and riding experience of vehicles.

[0003] Currently, vehicles are typically equipped with sunroofs and ambient lighting. However, since the light transmittance of ordinary glass is fixed, when the ambient lighting is turned on, in brighter scenarios, external light will enter the vehicle through the sunroof, potentially disrupting the ambient lighting and affecting the atmosphere it creates. Furthermore, in darker scenarios, the vehicle needs to provide light warnings to prevent external targets from contacting or colliding with it, which requires turning on the headlights. Simultaneously turning on both headlights and ambient lighting increases the vehicle's energy consumption. Summary of the Invention

[0004] In view of this, this application provides a dimming sunroof control method, device and vehicle that are linked with vehicle ambient lighting, in order to solve the problems that may be caused by the ambient lighting being turned on in different scenarios in the prior art, which may affect the atmosphere or increase power consumption.

[0005] Firstly, this application provides a method for controlling a dimming sunroof that is linked to vehicle ambient lighting, including:

[0006] Monitor the ambient lighting's activation signal;

[0007] The brightness level of the vehicle exterior is obtained, and the target dimming range of the vehicle dimming awning is determined based on the brightness level; wherein the transmittance of the dimming range corresponding to the bright exterior of the vehicle is less than the transmittance of the dimming range corresponding to the dim exterior of the vehicle.

[0008] If the activation signal is detected, a dimming command is output, which is used to instruct the transmittance of the dimming canopy to be adjusted to the target dimming range.

[0009] In one possible implementation, after detecting the enable signal, the following is also included:

[0010] Monitor the real-time brightness of the ambient light;

[0011] Accordingly, the dimming command is used to instruct the transmittance of the dimming canopy to change in the opposite direction to the change in real-time brightness within the target dimming range.

[0012] In one possible implementation, the minimum real-time brightness corresponds to the maximum transmittance within the target dimming range, and the maximum real-time brightness corresponds to the minimum transmittance within the target dimming range.

[0013] In one possible implementation, the target dimming range of the dimming canopy includes:

[0014] The first dimming range corresponds to a bright scene and the second dimming range corresponds to a dark scene;

[0015] The maximum transmittance of the first dimming range is not greater than the minimum transmittance of the second dimming range.

[0016] In one possible implementation, the transmittance of the first dimming range includes 0%-50%, and the transmittance of the second dimming range includes 50%-100%.

[0017] In one possible implementation, determining the target dimming range of the vehicle dimming canopy based on the brightness level includes:

[0018] The vehicle is currently in either the bright scene or the dark scene based on the brightness level.

[0019] If the vehicle is currently in the bright scene, then the target dimming range of the dimming canopy is determined to be the first dimming range;

[0020] If the vehicle is currently in the dark scene, then the target dimming range of the dimming canopy is determined to be the second dimming range.

[0021] In one possible implementation, the following is included before outputting the dimming command:

[0022] Record the light transmittance of the dimming canopy before dimming;

[0023] Following the output dimming command are:

[0024] The system monitors the ambient light's off signal. If the off signal is detected, a recovery command is output. The recovery command instructs the light transmittance of the dimming canopy to be restored to its original transmittance before dimming.

[0025] Secondly, this application provides a dimming sunroof control device that is linked to vehicle ambient lighting, including:

[0026] The monitoring module is used to monitor the ambient light's activation signal;

[0027] The acquisition module is used to acquire the brightness level of the vehicle exterior and determine the target dimming range of the vehicle dimming awning based on the brightness level; wherein, the transmittance of the dimming range corresponding to the bright exterior of the vehicle is less than the transmittance of the dimming range corresponding to the dim exterior of the vehicle.

[0028] An adjustment module is used to output a dimming command if the activation signal is detected. The dimming command is used to instruct the transmittance of the dimming canopy to be adjusted to the target dimming range.

[0029] Thirdly, this application provides a vehicle including a control device, the control device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method as described in the first aspect or any possible implementation of the first aspect.

[0030] Fourthly, this application provides a computer-readable storage medium storing a computer program, characterized in that, when executed by a processor, the computer program implements the steps of the method as described in the first aspect or any possible implementation of the first aspect.

[0031] This application provides a method, device, and vehicle for controlling a dimming sunroof that is linked to vehicle ambient lighting. The control method includes: monitoring an ambient lighting activation signal; acquiring the brightness level outside the vehicle and determining a target dimming range for the vehicle's dimming sunroof based on the brightness level; wherein the transmittance of the dimming range corresponding to bright conditions outside the vehicle is less than the transmittance of the dimming range corresponding to dim conditions outside the vehicle; if an activation signal is detected, outputting a dimming command, the dimming command being used to instruct the transmittance of the dimming sunroof to be adjusted to the target dimming range. By monitoring the ambient lighting activation signal in real time and determining the dimming range of the dimmable sunroof based on the real-time brightness of the vehicle's exterior, the sunroof's transmittance is controlled to remain within a low transmittance dimming range when the ambient lighting is turned on in a bright environment. This reduces the amount of external light entering the vehicle, ensuring the ambient lighting's luminous effect and providing a good driving experience for the user. Conversely, when the ambient lighting is turned on in a dim environment, the sunroof's transmittance is controlled to remain within a high transmittance dimming range. In this way, even without turning on the vehicle's headlights, the ambient lighting inside the car can still illuminate the external environment through the dimmable sunroof, serving as a warning to the vehicle's surroundings and reducing the vehicle's energy consumption to some extent.

[0038] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0040] Smart glass refers to a new type of special optoelectronic glass product with a laminated structure, where a liquid crystal film is laminated between two layers of glass and bonded together under high temperature and pressure. Depending on the control methods and principles, the smart glass can switch between transparent and opaque states through various means such as electronic control, temperature control, light control, or pressure control. With the trend towards intelligent and electric vehicles, many vehicles are equipped with smart sunroofs. These sunroofs are made of smart glass, allowing for the adjustment of the light entering the vehicle by regulating the light transmittance of the glass.

[0041] Based on this Figure 1This is a flowchart illustrating the implementation of the dimming canopy control method linked to vehicle ambient lighting provided in this application embodiment. Figure 1 As shown in the figure, this application provides a method for controlling a dimming sunroof that is linked to vehicle ambient lighting, including:

[0042] Step 101: Monitor the ambient light's activation signal.

[0043] Ambient lighting, also known as ambient lighting, is a product used to decorate cars and create an atmosphere. It is typically found on the steering wheel, center console, foot lights, cup holders, roof, welcome lights, door sills, trunk, and headlights.

[0044] Ambient lights for different vehicle models can correspond to different activation signals (i.e. activation methods). For example, the activation signal for ambient lights can be that the user manually turns on the corresponding switch; or it can be that it turns on automatically through a light sensor; or the user can also turn it on through the screen menu settings of the vehicle's central control system. This application does not limit this.

[0045] In step 101, for example, the vehicle central control system can communicate with the control switch of the ambient light. When the user turns on the ambient light, the control switch can send an on signal to the vehicle central control system. When the vehicle central control system receives the on signal, it can monitor the ambient light on signal.

[0046] In another possible implementation scenario, a light sensing device can be installed inside the vehicle. This device can contain a light sensor. When the light intensity inside the vehicle is lower than a set value, the ambient light will be automatically turned on. The device will also send an ambient light activation signal to the vehicle's central control system. Upon receiving the activation signal, the vehicle's central control system can monitor the ambient light activation signal.

[0047] In another possible scenario, users can also manually turn on the ambient lighting directly in the on-screen menu settings of the vehicle's central control system, and the vehicle's central control system can detect the ambient lighting activation signal in a timely manner.

[0048] Step 102: Obtain the brightness level of the vehicle exterior and determine the target dimming range of the vehicle dimming awning based on the brightness level; wherein, the transmittance of the dimming range corresponding to the bright exterior of the vehicle is less than the transmittance of the dimming range corresponding to the dim exterior of the vehicle.

[0049] In step 102, for example, an ambient light sensing device can be installed on the roof of the vehicle. This device contains an ambient light sensor and is connected to the vehicle body controller. The ambient light sensing device collects the current light intensity outside the vehicle and sends the collected light intensity signal to the vehicle body controller. After receiving the light intensity signal, the vehicle body controller determines the current brightness level outside the vehicle based on a pre-set correspondence between light intensity and brightness. This allows the vehicle body controller to output a corresponding dimming command to the dimming sunroof controller based on the brightness level when the vehicle's central control system detects the ambient light activation signal. The dimming sunroof controller can then adjust the light transmittance of the dimming sunroof based on the dimming command.

[0050] In another possible scenario, under severe weather conditions, placing the ambient light sensor on the roof of the vehicle may lead to inaccurate light information or even damage to the device. Therefore, the ambient light sensor can also be placed on the interior window of the vehicle for light collection. For example, the ambient light sensor can be placed on the rear window of the vehicle to achieve accurate light information collection inside the vehicle. This can effectively avoid the impact of inaccurate data collection by the ambient light sensor under severe weather conditions and also help improve the adjustment accuracy of the light transmittance of the dimming sunroof.

[0051] In this embodiment, the transmittance of the dimming range corresponding to the dimming canopy when the exterior of the vehicle is bright is less than the transmittance of the dimming range corresponding to the dimming canopy when the exterior of the vehicle is dim. For example, in bright environments, when the light transmittance of the dimmable sunroof is high, a large amount of light will pass through it and enter the vehicle's interior. If the ambient lighting is on at this time, it will be difficult for users to experience the effect created by the ambient lighting. In this case, the dimmable sunroof can be adjusted to a low light transmittance state to prevent too much light from entering the vehicle through it, ensuring the effect created by the ambient lighting and providing users with a more comfortable driving experience, thereby improving the user's experience. In dim environments, headlights can usually be turned on to make the vehicle bright and alert other vehicles or people outside the vehicle. However, this method often increases the vehicle's power consumption. Therefore, the light transmittance of the dimmable sunroof can be adjusted to a high light transmittance state, allowing the light from the ambient lighting inside the vehicle to pass through the dimmable sunroof and illuminate the external environment of the vehicle, thus alerting other objects outside the vehicle and preventing them from contacting or colliding with the vehicle. In this way, the problem of increased vehicle power consumption caused by turning on the headlights can be avoided, and the safety of users during the driving process can be guaranteed.

[0052] In one possible implementation, the target dimming range of the dimming canopy includes:

[0053] The first dimming range corresponds to a bright scene, and the second dimming range corresponds to a dark scene.

[0054] The maximum transmittance of the first dimming range shall not be greater than the minimum transmittance of the second dimming range.

[0055] In this embodiment, different dimming ranges are set for the light transmittance of the dimming sunroof in bright and dim scenes. For example, when a user turns on the ambient lights in a bright scene, to create an in-vehicle environment atmosphere that meets the user's needs, the dimming sunroof can be appropriately kept in a dimming range with a lower light transmittance (i.e., the first dimming range). This reduces the amount of light from the external environment entering the vehicle through the dimming sunroof, thus ensuring that the ambient lights create a suitable in-vehicle environment atmosphere. Conversely, when a user turns on the ambient lights in a dim scene, since the outside world is relatively dark, the dimming sunroof can be kept in a dimming range with a higher light transmittance (i.e., the second dimming range). This allows the light from the ambient lights inside the vehicle to pass through the dimming sunroof and illuminate the external environment, thereby alerting other vehicles or people around the vehicle and preventing contact or collision between the vehicle and them, ensuring the user's driving safety. To ensure that the ambient lighting inside the vehicle always creates an environment that meets the user's needs, the maximum light transmittance of the dimming sunroof in bright scenes can be limited to no more than the minimum light transmittance of the dimming sunroof in dim scenes. In this way, users can fully experience the in-vehicle environment created by the ambient lighting, whether in bright or dim scenes.

[0056] In one possible implementation, the transmittance of the first dimming range includes 0%-50%, and the transmittance of the second dimming range includes 50%-100%.

[0057] In this embodiment, the transmittance of the first dimming range can be 0%-50%, and the transmittance of the second dimming range can be 50%-100%. For example, when the vehicle is in a bright environment, the interior is usually also quite bright. If the user turns on the ambient lighting, the effect is not obvious. Therefore, if the transmittance of the dimming sunroof is simultaneously adjusted to a lower dimming range (e.g., 0%-50%), the brightness inside the vehicle can be reduced. In this case, the ambient lighting can create a pleasant in-car atmosphere. Conversely, when the vehicle is in a dim environment, the interior is also quite dark. If the ambient lighting is too bright and the transmittance of the dimming sunroof is low, it may pose a safety hazard to the user. Therefore, the transmittance of the dimming sunroof can be simultaneously adjusted to a higher dimming range (e.g., 50%-100%) based on the brightness of the ambient lighting. This ensures the user's safety while allowing them to fully experience the ambiance created by the ambient lighting.

[0058] In one possible implementation, determining the target dimming range of the vehicle dimming canopy based on brightness levels includes:

[0059] The vehicle is currently in a bright or dark scene based on the level of brightness.

[0060] If the vehicle is currently in a bright scene, then the target dimming range of the dimming canopy is determined as the first dimming range.

[0061] If the vehicle is currently in a dark scene, then the target dimming range of the dimming canopy is determined to be the second dimming range.

[0062] In this embodiment, after the body controller determines the brightness level of the vehicle's exterior, it can also determine the environment in which the vehicle is located based on the brightness level, and determine the adjustment range of the light transmittance of the dimming sunroof according to the environment in which the vehicle is located. For example, in a bright scene, if a user turns on the vehicle's ambient lighting and the translucent sunroof has a transmittance of 100%, the interior environment will still be bright. Even with the ambient lighting on, the created ambiance may not be noticeable. Therefore, the translucent sunroof can be adjusted within a lower transmittance range (e.g., between 0% and 50%) to ensure the ambient lighting creates an ambiance that meets the user's needs. Conversely, when the vehicle is in a dim scene, the user turns on the ambient lighting. Since both the interior and exterior are relatively dark, the translucent sunroof can be adjusted within a higher transmittance range (e.g., between 50% and 100%). By adapting to different brightness levels and adjusting the translucent sunroof's transmittance within a specific range, the user's various sensory entertainment needs in different environments can be met, creating an immersive and relaxing experience.

[0063] Step 103: If an activation signal is detected, a dimming command is output. The dimming command is used to instruct the transmittance of the dimming canopy to be adjusted to the target dimming range.

[0064] In step 103, for example, when the vehicle central control system detects the activation signal of the vehicle ambient lights, it sends the activation signal to the body controller. After receiving the activation signal, the body controller determines the current brightness level of the vehicle's exterior, generates a dimming command based on the brightness level signal, and sends the dimming command to the dimming sunroof controller. After receiving the dimming command, the dimming sunroof controller adjusts the light transmittance of the dimming sunroof to the target dimming range.

[0065] In summary, this application provides a method for controlling a dimming sunroof that is linked to vehicle ambient lighting. The method includes: monitoring an ambient lighting activation signal; acquiring the brightness level outside the vehicle and determining a target dimming range for the vehicle's dimming sunroof based on the brightness level; wherein the transmittance of the dimming range corresponding to bright conditions outside the vehicle is less than the transmittance of the dimming range corresponding to dim conditions outside the vehicle; if an activation signal is detected, a dimming command is output, which instructs the transmittance of the dimming sunroof to be adjusted to the target dimming range. By monitoring the ambient lighting activation signal in real time and determining the dimming range of the dimmable sunroof based on the real-time brightness of the vehicle's exterior, the sunroof's transmittance is controlled to remain within a low transmittance dimming range when the ambient lighting is turned on in a bright environment. This reduces the amount of external light entering the vehicle, ensuring the ambient lighting's luminous effect and providing a good driving experience for the user. Conversely, when the ambient lighting is turned on in a dim environment, the sunroof's transmittance is controlled to remain within a high transmittance dimming range. In this way, even without turning on the vehicle's headlights, the ambient lighting inside the car can still illuminate the external environment through the dimmable sunroof, serving as a warning to the vehicle's surroundings and reducing the vehicle's energy consumption to some extent.

[0066] In one possible implementation, after detecting the enable signal, the following is also included:

[0067] Step 104: Monitor the real-time brightness of the ambient light.

[0068] Correspondingly, the dimming command is used to instruct the transmittance of the dimming canopy to be adjusted in the opposite direction to the target dimming range as the real-time brightness changes.

[0069] Figure 2 This is a flowchart illustrating the implementation of another dimming sunroof control method linked to vehicle ambient lighting, as provided in an embodiment of this application. Figure 2 As shown in step 104, when the vehicle's central control system detects that the ambient lights are on, it can also monitor the real-time brightness changes of the ambient lights and adjust the light transmittance of the dimming sunroof to correspond to the brightness changes of the ambient lights within the target dimming range. When the brightness of the ambient lights decreases, the light transmittance of the dimming sunroof is controlled to increase accordingly. For example, the brightness levels of the ambient lights can be set to correspond to the light transmittance levels of the dimming sunroof. For each level increase in the brightness of the ambient lights, the light transmittance of the dimming sunroof is controlled to decrease by one level. Alternatively, a light sensor can be added to the dimming sunroof so that it can intelligently and automatically adjust its light transmittance according to the brightness of the ambient lights in the vehicle. In this way, the linkage between the brightness of the ambient lights and the light transmittance of the dimming sunroof is realized, and a privacy mode with adjustable light transmittance levels of the dimming sunroof is added to the interior space, thereby effectively improving the user's driving experience.

[0070] In one possible implementation, the minimum real-time brightness corresponds to the maximum transmittance within the target dimming range, and the maximum real-time brightness corresponds to the minimum transmittance within the target dimming range.

[0071] In this embodiment, for example, when the real-time brightness of the vehicle ambient light is at its minimum, the dimming sunroof controller adjusts the transmittance of the dimming sunroof to the maximum transmittance within the target adjustment range; when the real-time brightness of the vehicle ambient light is at its maximum, the dimming sunroof controller adjusts the transmittance of the dimming sunroof to the minimum transmittance within the target adjustment range. Thus, when a user adjusts the brightness of the vehicle ambient light to its brightest state in a bright environment, the dimming sunroof is at the minimum transmittance state within the corresponding target dimming range. For example, the minimum transmittance can be 0%, at which point excessive external light will not penetrate the vehicle interior, creating a relatively dim environment that allows the ambient light to create a suitable atmosphere and provide the user with a good visual experience. The dimming sunroof provides a superior driving experience and effectively protects user privacy, offering a more comfortable and safer driving environment. When the user adjusts the ambient lighting to its brightest setting in a dim environment, the sunroof operates at its minimum transmittance within the target dimming range. For example, this minimum transmittance can be 50%. At this time, the ambient light inside the vehicle can be diffused through the sunroof into the external environment, serving as a warning to other vehicles or people around the vehicle. This helps prevent the increased energy consumption caused by turning on the headlights. The ambient light passing through the sunroof can also remind other people or vehicles to maintain a proper distance from the vehicle, thereby ensuring the safety of the user and others.

[0072] In one possible implementation, the following is included before outputting the dimming command:

[0073] Step 105: Record the light transmittance of the dimming canopy before dimming.

[0074] Following the output dimming command are:

[0075] Step 106: Monitor the ambient light's off signal. If an off signal is detected, output a recovery command. The recovery command is used to instruct the light transmittance of the dimming canopy to be restored to the light transmittance before dimming.

[0076] Figure 3 This is a flowchart illustrating the implementation of another dimming sunroof control method linked to vehicle ambient lighting, as provided in this application embodiment. Figure 3As shown, in step 105, before the vehicle body controller outputs the dimming command, the current transmittance of the dimming sunroof is pre-recorded so that the transmittance of the dimming sunroof can be adjusted to that transmittance later. For example, before outputting the dimming command, the vehicle body controller pre-records the current transmittance of the dimming sunroof (e.g., 21%), and then the vehicle body controller outputs the dimming command to the dimming sunroof controller, which adjusts the transmittance of the dimming sunroof based on the dimming command.

[0077] In step 106, after the body controller outputs the dimming command, the vehicle central control system will also monitor the ambient light's off signal in real time. When the ambient light's off signal is detected, the body controller will output a recovery command to the dimming sunroof controller. Correspondingly, the dimming sunroof controller can adjust the light transmittance of the dimming sunroof to the light transmittance before dimming, that is, adjust the light transmittance of the dimming sunroof to 21%.

[0078] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0096] If the vehicle is currently in a bright scene, then the target dimming range of the dimming canopy is determined as the first dimming range.

It monitors the ambient lighting's activation signal; obtains the brightness level outside the vehicle; and determines the target dimming range of the vehicle's dimming sunroof based on the brightness level. The transmittance of the dimming range corresponding to bright external lighting is less than the transmittance of the dimming range corresponding to dim external lighting. If an activation signal is detected, a dimming command is output, instructing the transmittance of the dimming sunroof to be adjusted to the target dimming range. By monitoring the ambient lighting activation signal in real time and determining the dimming range of the dimmable sunroof based on the real-time brightness of the vehicle's exterior, the sunroof's transmittance is controlled to remain within a low transmittance dimming range when the ambient lighting is turned on in a bright environment. This reduces the amount of external light entering the vehicle, ensuring the ambient lighting's luminous effect and providing a good driving experience for the user. Conversely, when the ambient lighting is turned on in a dim environment, the sunroof's transmittance is controlled to remain within a high transmittance dimming range. In this way, even without turning on the vehicle's headlights, the ambient lighting inside the car can still illuminate the external environment through the dimmable sunroof, serving as a warning to the vehicle's surroundings and reducing the vehicle's energy consumption to some extent.

[0104] In summary, this application provides a vehicle that monitors the ambient light activation signal; obtains the brightness level outside the vehicle, and determines the target dimming range of the vehicle's dimming sunroof based on the brightness level; wherein the transmittance of the dimming range corresponding to bright external lighting is less than the transmittance of the dimming range corresponding to dim external lighting; if an activation signal is detected, a dimming command is output, which instructs the transmittance of the dimming sunroof to be adjusted to the target dimming range. By monitoring the ambient lighting activation signal in real time and determining the dimming range of the dimmable sunroof based on the real-time brightness of the vehicle's exterior, the sunroof's transmittance is controlled to remain within a low transmittance dimming range when the ambient lighting is turned on in a bright environment. This reduces the amount of external light entering the vehicle, ensuring the ambient lighting's luminous effect and providing a good driving experience for the user. Conversely, when the ambient lighting is turned on in a dim environment, the sunroof's transmittance is controlled to remain within a high transmittance dimming range.
