Embodiments for Carrying out the Invention

[0015] Hereinafter, referring to the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly described. It is clear that the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art belong to the protection scope of the present disclosure.

[0016] Terms such as "first", "second", etc. in the specification and claims of the present application are terms for distinguishing similar objects, and are not for explaining a specific order or priority. It should be understood that such terms can be exchanged when appropriate so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein. The objects distinguished by "first" and "second" are usually of one kind, and do not limit the number of objects. For example, the first object may be one or at least two. Further, "and / or" in the specification and claims represents at least any one of the connected objects, and the symbol " / " generally represents that the related objects before and after are in an "or" relationship.

[0017] Dimmable glass is an important development direction for automotive glass. Currently, dimmable glass mainly comes in three types: electrochromic, polymer liquid crystal, dye liquid crystal, and suspended particle. As an example, in electrochromism, by applying a voltage to the electrodes at both ends of the element, particles move into (or out of) the electrochromic layer due to the action of the electric field of the applied voltage, resulting in a decrease (or increase) in the valence of the electrochromic material, a change in the color of the electrochromic material before equilibrium, and a stabilization of the color of the electrochromic material after equilibrium. Polymer liquid crystal adds a layer of liquid crystal dimming film between the glass layers, so that when power is turned on, the polymer liquid crystal material in the liquid crystal film is regularly arranged, making the glass transparent, otherwise it exhibits a light-transmitting but opaque appearance. The driving voltage and response speed differ depending on the type of dimmable glass. The dimmable glass referred to in the embodiments of this application below may be any one of the above types of glass.

[0018] In related technologies, the control of in-vehicle dimmable glass was primarily performed via corresponding buttons in the in-vehicle cockpit system. The cockpit system transmitted electrical signals to the dimmable glass through a standard control interface. Furthermore, since the dimmable glass could also acquire various sensor data detected by the smart cockpit, interaction between the cockpit system and the dimmable glass was also possible. In these technologies, to adjust the light transmittance, the user had to manually control the corresponding buttons in the cockpit system to send corresponding control signals to the dimmable glass. This manual adjustment method lacked sufficient flexibility, as the user could only control the glass's light transmittance after unlocking the vehicle and entering the cabin. The user could not adjust the glass's light transmittance while outside the vehicle.

[0019] In view of the problems existing in the related art, the present application designs a method for controlling a dimming glass. This method obtains distance information between a target object and a vehicle, generates an input signal for the corresponding dimming glass according to the distance information, and automatically adjusts the light transmittance of the dimming glass by the input signal, so as to realize flexible adjustment control of the light transmittance of the glass without the need for manual control by the user and improve the user experience.

[0020] In the first aspect, referring to FIG. 1, a flowchart of the steps of a method for controlling a dimming glass according to an embodiment of the present application is shown. The method may include the following steps S101 to S103.

[0021] Step S101: Obtain distance information between a target object and a vehicle.

[0022] Here, the target object may be any object or moving object that can be used to assist in detecting distance information. The distance information indicates the distance between the target object and the vehicle. In a specific implementation, the distance information between the target object and the vehicle is obtained through the vehicle's smart cockpit system. For example, first, the position information of the target object and the position information of the vehicle are obtained respectively, and then, according to the position information of the target object and the position information of the vehicle, the distance information between the two may be determined. In this embodiment, step S101 can be automatically executed cyclically without the need for the user to manually trigger. That is, when the target object is far enough away from the vehicle and the distance information cannot be obtained, the execution of subsequent steps is stopped. When the target object is close enough to the vehicle or within a certain range, the position information of the target object is obtained and the subsequent steps are automatically executed.

[0023] Step S102: Control an input signal of the dimming glass of the vehicle according to the distance information.

[0024] Step S103: Change the light transmittance of the dimming glass by the input signal.

[0025] In a specific implementation, dimmable glass can be used as a component of the vehicle's smart cockpit system. Distance information is acquired through the smart cockpit system. The smart cockpit system controls the input signal of the vehicle's dimmable glass according to the distance information and transmits the corresponding input signal to the dimmable glass through a standard control interface, thereby causing the dimmable glass to change its light transmittance in response to the input signal. Here, the input signal may be a voltage signal or a current signal.

[0026] Furthermore, as the vehicle's primary smart control system, the smart cockpit system can acquire multifaceted vehicle information through its mounted sensors, specifically including vehicle area information (digital key, window lift switch, door handle, door lock, tailgate lock, seat adjustment motor, seat heater, seat ventilation fan, seat adjustment switch, seat belt buckle, exterior mirror adjustment motor, exterior mirror folding motor, wiper switch, headlight switch, charging port cover switch), thermal management information (temperature sensor, pressure sensor, sunlight sensor, PM2.5 sensor, electric air outlet switch), power area information (charging electronic lock, P gear switch, AC charging port, DC charging port, high voltage battery control service, high voltage battery query service, MCU control service, MCU query service, etc.), and chassis area information (brake pedal switch sensor, accelerator pedal stroke sensor, collision hardline sensor). In a specific implementation, the smart cockpit system can control the input signal of the dimmable glass by combining distance information and the vehicle information it has acquired, thereby enabling a change in the dimming rate.

[0027] From the steps described above, it has been found that the embodiment of the present invention improves the user experience by detecting changes in the distance between the target object and the vehicle according to the acquired distance information between the target object and the vehicle, and by controlling the input signal of the dimmable glass according to the distance information, thereby achieving dynamic adjustment of the light transmittance of the dimmable glass. Embodiment 1

[0028] This embodiment describes an example of acquiring distance information between a target object and a vehicle.

[0029] The target object is the digital key of the vehicle, and the step of acquiring distance information between the target object and the vehicle is: Depending on the type of the digital key, the step is to obtain the distance parameter value of the digital key, The process includes the step of determining distance information between the digital key and the vehicle based on the distance parameter value.

[0030] Here, "digital key" refers to a technology that binds terminals such as mobile phones and smart wearable devices to a digital key as compatible mobile devices, and uses a precise positioning technology algorithm to enable keyless starting and control of the vehicle from the compatible mobile device. Currently, digital keys are mainly divided into three categories: Bluetooth® (BLE) digital keys, Near Field Communication (NFC) keys, and Ultra Wide Band (UWB) digital keys. Taking Bluetooth® digital keys as an example, a car owner can use a digital key after binding their mobile phone to the Bluetooth® digital key as a control terminal, adding their mobile phone number to the digital key management interface, downloading the corresponding app, and creating the digital key. When the car owner brings their mobile phone close to the vehicle, a Bluetooth® connection is established between the control terminal and the vehicle, thereby enabling automatic control of the vehicle. In this embodiment, the digital key may represent a mobile device bound to the vehicle's digital key, the distance parameter value of the digital key represents the distance parameter value of the mobile device, and the distance information between the digital key and the vehicle represents the distance information between the mobile device and the vehicle.

[0031] In a specific implementation, after the vehicle establishes a connection with the digital key, it is necessary to obtain the distance parameter value of the digital key. If the terminal bound to the digital key is far from the vehicle and the vehicle cannot establish a connection with the digital key, the distance parameter value of the digital key cannot be obtained, and the execution of subsequent steps is stopped. If the terminal bound to the digital key is close to the vehicle and it is detected that the vehicle has established a connection with the digital key, the vehicle will detect the distance to the digital key and automatically obtain the distance parameter value of the digital key. Different types of digital keys establish different connections. Specifically, a Bluetooth® connection is established between the BLE digital key and the vehicle, and a UWB connection is established between the UWB digital key and the vehicle.

[0032] Depending on the type of digital key, the distance parameter value of that digital key is obtained. In specific implementations, the positioning method and distance measurement method for digital keys differ because the type of digital key is different. If the digital key is a BLE digital key, the vehicle calculates and obtains the distance parameter value of the BLE digital key through the Received Signal Strength Indication (RSSI) algorithm of the BLE digital key. Alternatively, the vehicle can calculate the angle of the BLE digital key through the Angle of Arrival (AOA) algorithm of the BLE digital key and obtain the distance parameter value of the BLE digital key. If the digital key is a UWB digital key, the vehicle can calculate and obtain the distance parameter value of the UWB digital key using the time-of-flight distance measurement method of the UWB digital key.

[0033] The distance information between the digital key and the vehicle is determined according to the distance parameter value. In a specific implementation, the functional area may be pre-divided according to the functional requirements of the vehicle. As an example, referring to Figure 2, which shows a schematic diagram of area division, in the area where the distance between the digital key and the vehicle exceeds 30m, the digital key needs to perform the function of establishing a connection with the vehicle and performing authentication. In the area where the distance between the digital key and the vehicle is 8 to 15m (for example, area R5 in Figure 2), the digital key needs to perform the function of remotely controlling the vehicle's welcome lights. In the area where the distance between the digital key and the vehicle is 5 to 8m (for example, area R4 in Figure 2), the digital key needs to perform the function of locking the vehicle when the user is away from the vehicle. In the area where the distance between the digital key and the vehicle is less than 3m (for example, area R3 in Figure 2), the digital key needs to perform the function of unlocking the vehicle when the user approaches the vehicle. In areas where the distance between the digital key and the door is less than 1 meter (for example, area R2 in Figure 2), the digital key must perform a passive entry function. Also, in the interior area of ​​the vehicle (for example, area R1 in Figure 2), the digital key must perform a function to control the starting of the vehicle. In another example, the area division can be customized by the user. Therefore, by performing area division according to the above functional requirements and determining the functional area in which the digital key resides based on the distance parameter value of the digital key, this can be used as distance information between the digital key and the vehicle.

[0034] In the above embodiment 1, when the target is a digital key, a method for acquiring distance information between the target and the vehicle is described, and the distance information between the target and the vehicle is acquired quickly and accurately by utilizing the distance measurement and positioning functions of the digital key itself. Embodiment 2

[0035] In this embodiment, an example of controlling dimmable glass when the vehicle is equipped with keyless entry and ignition functions is described. The method for controlling the dimmable glass is as follows: The steps include detecting whether or not a vehicle unlock operation by the target object has been detected, Before the vehicle unlock operation is detected, the light transmittance of the dimmable glass is maintained at a first light transmittance; If the vehicle unlock operation is detected, the light transmittance of the dimmable glass is adjusted to a second light transmittance that is higher than the first light transmittance; if the vehicle door is detected to have been opened after the vehicle unlock operation is detected, the light transmittance of the dimmable glass is adjusted to a third light transmittance that is lower than the second light transmittance; If it is determined that the vehicle enters a pre-operation state after detecting that the door of the vehicle has been opened, the further step includes adjusting the light transmittance of the dimmable glass to a fourth light transmittance that is lower than the second light transmittance.

[0036] In specific implementations, vehicles may be equipped with keyless entry and functionality, and for example, the vehicle can be set to NFC unlock mode or fingerprint unlock mode. NFC unlock mode means that the user unlocks the vehicle by bringing an NFC-enabled device (mobile phone or mobile wearable device) close to the card swipe sensing area on the vehicle body. Fingerprint unlock mode means that the user collects a fingerprint image at the fingerprint recognition area on the vehicle body, and the vehicle is unlocked upon successful fingerprint recognition.

[0037] The system detects whether or not a vehicle unlock operation by the target object has been detected. For example, if the vehicle detects that the target object has brought an NFC-enabled device close to the vehicle's card swipe sensing area and received NFC information, or that the target object has collected a fingerprint image in the vehicle's fingerprint recognition area and successfully identified the fingerprint, it means that a vehicle unlock operation by the target object has been detected, and this determines the distance information between the target object and the vehicle. Specifically, this distance information indicates that the target object is near the vehicle's card swipe sensing area or in the vehicle's fingerprint recognition area.

[0038] Before the vehicle's unlock operation is detected, the light transmittance of the dimmable glass is maintained at a first light transmittance. If the vehicle's unlock operation is not detected, it means that the target is far away from the vehicle and has not yet reached the designated area (near the vehicle's card swipe sensing area or fingerprint identification area). In this case, to protect the privacy of the car owner and prevent other pedestrians passing by the vehicle from obtaining information inside the vehicle, the dimmable glass cannot be made transparent. The light transmittance of the dimmable glass can be maintained at a first light transmittance, and optionally, this first light transmittance may be the minimum light transmittance.

[0039] If a vehicle unlock operation is detected, it indicates that the target has touched the unlock area or corresponding button, or that the target is in the vehicle's card swipe sensing area or fingerprint recognition area. The light transmittance of the dimmable glass can be adjusted to a second light transmittance, which is greater than the first light transmittance. This allows the system to acquire information about the interior of the vehicle in advance through the dimmable glass, provided the target is in its current position and the door is not open. If the vehicle's door is detected to have been opened after a vehicle unlock operation is detected, the light transmittance of the dimmable glass can be adjusted to a third light transmittance, which is lower than the second light transmittance, as the target no longer needs to observe the interior of the vehicle through the dimmable glass. If the system determines that the vehicle should enter a pre-operation state after detecting that the vehicle's door has been opened, and accordingly detects that the target is in the interior area, the system can determine that the vehicle should enter a pre-operation state. To prevent pedestrians passing by the vehicle from obtaining information about the interior, the light transmittance of the dimmable glass is adjusted to a fourth light transmittance, which is lower than the second light transmittance.

[0040] Embodiment 3 described above describes a method for controlling the dimmable glass when the vehicle is equipped with keyless entry and activation functions. By sensing a vehicle unlock operation by a target, when an unlock operation by the corresponding vehicle is detected, it is determined that the target is near the card swipe sensing area of ​​the vehicle body or in the fingerprint recognition area of ​​the vehicle body, and thereafter the light transmittance of the dimmable glass is adjusted to a second light transmittance, allowing the target to acquire internal vehicle information in advance before unlocking, enabling dynamic adjustment of the light transmittance of the dimmable glass and improving the user experience. Embodiment 3

[0041] This embodiment describes an example of acquiring distance information between a target object and a vehicle.

[0042] The system detects whether the vehicle is connected to a target network permitted by the target object. Depending on whether the vehicle is connected to the target network, distance information between the target object and the vehicle is determined.

[0043] In a specific implementation, the target object may be a home gateway. When it is detected that the vehicle is connected to a target network (which may be Wi-Fi or Bluetooth) permitted by the home gateway, it indicates that the vehicle has entered the coverage area of ​​the target network, for example, the home garage. In this case, if the vehicle is connected to the target network, the distance information between the vehicle and the target object indicates that the vehicle is within the coverage of the target network; if the vehicle is not connected to the target network, the distance information between the vehicle and the target object indicates that the vehicle is outside the coverage of the target network.

[0044] In the above embodiment 3, a method for obtaining distance information between a target object and a vehicle was described by detecting whether or not the vehicle is connected to the target network. If the vehicle is connected to the target network, the distance information indicates that the vehicle has entered the coverage area of ​​the target network. Therefore, by detecting whether or not the vehicle is connected to the target network, distance information between the target object and the vehicle can be obtained quickly and accurately. Embodiment 4

[0045] In this embodiment, the method for controlling the dimmable glass before acquiring distance information between the target object and the vehicle is as follows: Steps include obtaining data collected about the target, The process further includes the step of identifying, based on the collected data, whether or not the target is the driver of the vehicle. The step of obtaining distance information between the target object and the vehicle is: If the target is identified as the driver of the vehicle, the method includes the step of acquiring distance sensing data or trajectory data of the driver.

[0046] In a concrete implementation, the vehicle first needs to identify the target. It acquires data collected about the target and, based on the collected data, identifies whether the target is the vehicle's driver. Specifically, the collected data may be treated as image data, a camera capable of recognizing faces may be mounted on the vehicle, and the driver's facial information may be recorded and stored through facial recognition. In actual use, when the target walks into the area around the vehicle and enters the camera's field of view, the camera acquires images of the area around the vehicle in real time, identifies the image containing the target, and identifies whether the target is the vehicle's driver based on that image. Alternatively, the collected data may be treated as mark data for a digital key, thereby identifying whether the target possessing that digital key is the vehicle's driver based on the mark on the digital key. Alternatively, the collected data may be treated as characteristic information of the target, such as gait, trajectory, and voice, and thereby identify whether the target is the vehicle's driver based on that characteristic information.

[0047] If the target is identified as the driver of a vehicle, distance sensing data or trajectory data of that driver is acquired. Specifically, after determining that the target is the driver, distance information between the target and the vehicle is acquired. This distance information may be the driver's distance sensing data or trajectory data.

[0048] Optionally, the vehicle may detect changes in the driver's depth information through on-board sensors such as on-board cameras, radar, and lasers, calculate distance sensing data based on these changes, and obtain the distance between the driver and the vehicle. The vehicle may also acquire driver trajectory data through corresponding sensors and determine whether the driver intends to unlock the vehicle by detecting the driver's trajectory. Specifically, the driver's movement trajectory may indicate that the driver is approaching the vehicle and intends to unlock it. The vehicle controls the input signal to change the light transmittance of the dimmable glass. If the driver's movement trajectory indicates that the driver is merely passing by the vehicle and does not intend to unlock it, the vehicle does not change the light transmittance of the dimmable glass.

[0049] In the above embodiment 4, the target object is identified by acquiring data collected about the target object, and after identifying that the target object is the driver of the vehicle, the driver's distance sensing data or trajectory data is acquired. This facilitates the subsequent modification of the dimmable glass according to the driver's distance sensing data or trajectory data, thereby realizing flexible adjustment control of the light transmittance of the dimmable glass. Embodiment 5

[0050] In this embodiment, an example of adjusting the light transmittance of the vehicle's dimmable glass according to the distance information will be described.

[0051] Before acquiring distance information between the target object and the vehicle, the light transmittance of the vehicle's tinted glass is maintained at its initial light transmittance. The step of controlling the input signal of the vehicle's dimmable glass according to the distance information is as follows: If the distance information indicates that the target object is within a first distance range, the input signal of the vehicle's dimmable glass is the input signal for the first light transmittance, and the vehicle is controlled so that the first distance range is within the distance range inside the vehicle. If the distance information indicates that the target object is within a second distance range, the vehicle's dimmable glass input signal is the second light transmittance input signal, and the vehicle is controlled so that the second distance range is within a first target distance range outside the vehicle. If the distance information indicates that the target object is within a third distance range, the step includes controlling the vehicle's dimmable glass so that the input signal is a third light transmittance input signal, the third distance range is a second target distance range outside the vehicle, and the lower limit of the second target distance range is greater than the upper limit of the first target distance range. The third light transmittance is lower than the first light transmittance and also lower than the second light transmittance.

[0052] In a specific implementation, the light transmittance of the vehicle's tinted glass is maintained at its initial light transmittance before acquiring distance information between the target object and the vehicle. If the vehicle cannot acquire distance information before acquiring distance information between the target object and the vehicle, it indicates that the distance between the target object and the vehicle is too far, and the light transmittance of the tinted glass is maintained at its initial light transmittance. Generally, the initial light transmittance is relatively low and serves to protect the privacy of the car owner. In actual use, the initial light transmittance may be set by the user. Optionally, the initial light transmittance may be the minimum light transmittance.

[0053] By acquiring distance information between the corresponding target object and the vehicle, the distance range of vehicles in which the target object exists can be determined based on the acquired distance information. The light transmittance of the dimmable glass is then adjusted according to the distance range of vehicles in which the target object exists.

[0054] Case 1: When the distance information indicates that the target is within a first distance range, the input signal of the vehicle's dimmable glass is set to the input signal for the first light transmittance, and control is performed so that the first distance range is within the vehicle's interior distance range. The vehicle's interior area is determined as the vehicle's first distance range, and if it is determined that the target is within the first distance range according to the distance information, control is performed so that the input signal of the vehicle's dimmable glass is set to the input signal for the first light transmittance, thereby adjusting the light transmittance to the first light transmittance. Optionally, the first light transmittance is lower than the second light transmittance. In this embodiment, after it is determined that the target has entered the vehicle according to the distance information, the light transmittance of the dimmable glass is appropriately reduced (adjusted to the first light transmittance), protecting the privacy information of the target inside the vehicle, eliminating the need for the user to manually adjust the light transmittance after entering the vehicle, and improving the user experience.

[0055] Case 2: If the distance information indicates that the target object is within the second distance range, the input signal for the vehicle's dimmable glass is set to the input signal for the second light transmittance, and control is performed so that the second distance range is within the first target distance range outside the vehicle. The first target distance range outside the vehicle is determined as the second distance range. For example, an area within a 10m radius outside the vehicle is determined as the second distance range. If, according to the distance information, it is determined that the target object is within the second distance range, control is performed so that the input signal for the vehicle's dimmable glass is set to the input signal for the second light transmittance, thereby adjusting the light transmittance to the second light transmittance. The second light transmittance is higher than the first light transmittance and the third light transmittance. Generally, when the vehicle is closed or locked, the vehicle's dimmable glass is opaque to protect user privacy. When a user wants to obtain information from inside a vehicle, they need to open the door and enter the vehicle. Alternatively, when a user wants to improve the light transmittance of the window glass, they need to control the corresponding button on the cockpit system from inside the vehicle to select the appropriate light transmittance. In this embodiment, distance information is obtained, and if the distance information indicates that the target is within a second distance range, the light transmittance of the dimmable glass is automatically increased to the second light transmittance. This makes it easier for the target to observe the inside of the vehicle through the glass and obtain the desired information, thereby achieving automatic control of the light transmittance of the dimmable glass and improving the user experience.

[0056] Case 3: When the distance information indicates that the target object is within the third distance range, the input signal of the vehicle's dimmable glass is set to be the input signal for the third light transmittance, the third distance range is set to be the second target distance range outside the vehicle, and the control is performed so that the lower limit of the second target distance range is greater than the upper limit of the first target range. The second target distance range outside the vehicle is set to be the third distance range, and the lower limit of the second target distance range is set to be greater than the upper limit of the first target distance range. For example, the first target range is the area within a 10m radius outside the vehicle, and the lower limit of the second target distance range must be greater than 10m. Therefore, the lower limit of the second target distance range must be greater than 10m, and for example, the third distance range is the area within a 20-15m radius outside the vehicle. If it is determined that the target object is within the third distance range according to the distance information, the control is performed so that the input signal of the vehicle's dimmable glass is the input signal for the third light transmittance, thereby adjusting the light transmittance to the third light transmittance. The third light transmittance is lower than the first light transmittance and also lower than the second light transmittance, and when the target object is far away from the vehicle, the light transmittance of the vehicle's tinted glass can be kept low to protect the privacy of the car owner.

[0057] In one possible embodiment, if the target object is the vehicle's digital key and the digital key has not established a communication connection with the vehicle, the light transmittance of the vehicle's dimmable glass is maintained at its current light transmittance. The step of obtaining distance information between the target object and the vehicle is: If the target object is the vehicle's digital key and the digital key has established a communication connection with the vehicle, the method includes the step of obtaining distance information between the digital key and the vehicle, depending on the type of digital key.

[0058] Referring to Figure 3, which shows a schematic diagram of distance range division, as shown in Figure 3, when the target object is a vehicle's digital key, the vehicle's distance range can be divided into three main parts depending on whether the digital key can establish a connection with the vehicle or not. According to the above embodiment, the distance range outside the vehicle in which the digital key can establish a connection with the vehicle is determined as the second distance range, the distance range outside the vehicle in which the digital key cannot establish a connection with the vehicle is determined as the third distance range, and the distance range inside the vehicle in which the digital key can establish a connection with the vehicle is determined as the first distance range.

[0059] In a specific implementation, refer to Figure 4, which shows a schematic diagram of the flow for acquiring distance information. As shown in Figure 4, if the vehicle is equipped with a digital key, first, it is determined whether or not the digital key has established a connection with the vehicle. If the digital key has not established a connection with the vehicle, it is determined that the target object (digital key) is outside the vehicle in a third distance range. Since the digital key is far away from the vehicle, there is no need to adjust the light transmittance of the vehicle's glass, and the light transmittance of the vehicle's tinted glass is maintained at the current light transmittance (e.g., third light transmittance).

[0060] When the system detects that the vehicle has established a connection with the digital key, it acquires distance information between the digital key and the vehicle. For specific details on how to acquire distance information, refer to the contents of Embodiment 1. Depending on the type of digital key, the distance parameter value of the digital key is acquired, and the distance information between the digital key and the vehicle is determined according to the acquired distance parameter value of the digital key. Referring to Figure 4, after it is determined that the digital key has established a connection with the vehicle, it is further determined, according to the acquired distance information, whether or not the digital key is inside the vehicle. If the digital key is inside the vehicle, it is determined that the target is within a first distance range, and the light transmittance of the dimmable glass is adjusted to the first light transmittance. If the digital key is not inside the vehicle, it is determined that the target is within a second distance range, and the light transmittance of the dimmable glass is adjusted to the second light transmittance. Embodiment 6

[0061] In this embodiment, we will describe an example in which, in Embodiment 5, when the distance information indicates that the target object is within the second distance range, the input signal of the vehicle's dimmable glass is controlled to be the input signal of the second light transmittance.

[0062] If the distance information indicates that the target object is within a second distance range, the distance level to which the distance information belongs is determined. Depending on the distance level to which the distance information belongs, the vehicle's dimmable glass is controlled to be an input signal that gradually adjusts the light transmittance of the dimmable glass to the second light transmittance.

[0063] In a specific implementation, the second light transmittance can be expressed as a specific value, as a range of light transmittance values, or as a multi-stage light transmittance for multiple distance levels, with each level of light transmittance corresponding to one distance level. As an example, as shown in Figure 2, distance levels R5, R4, R3, R2, and R1 each correspond to one light transmittance. If the distance information indicates that the target object is within a second distance range outside the vehicle, the distance level between the target object and the vehicle can be further determined, and the corresponding light transmittance can be determined according to the distance level.

[0064] Depending on the distance level to which the distance information belongs, the input signal to the vehicle's dimmable glass is controlled to be an input signal that gradually adjusts the light transmittance of the dimmable glass to a second light transmittance. When adjusting the light transmittance, to prevent abrupt changes in light transmittance from affecting the user, the input signal can be used to adjust the light transmittance gradually according to the level, eventually adjusting it to the second light transmittance. In this embodiment, the distance level is further divided according to the distance information, and the light transmittance is adjusted to the corresponding level according to the corresponding distance level, thereby realizing flexible adjustment control of light transmittance. This allows the car owner to obtain information about the vehicle's internal environment through the dimmable glass without entering the vehicle, and to decide whether or not to use the vehicle based on the acquired information. Embodiment 7

[0065] In this embodiment, we will describe an example in which, according to Embodiment 6, the input signal to the dimmable glass of the vehicle is controlled to be an input signal that adjusts the light transmittance of the dimmable glass to the second light transmittance in steps, depending on the distance level to which the distance information belongs.

[0066] The second distance range includes a plurality of levels, a connection area level, a welcome area level, and an unlock area level, where the distance from the vehicle outside the vehicle gradually decreases, and the multi-stage light transmittance includes a plurality of light transmittances, a connection area light transmittance, and an unlock area light transmittance, where the light transmittance gradually increases, and the step of controlling the input signal of the vehicle's dimming glass to be an input signal that gradually adjusts the light transmittance of the dimming glass to the second light transmittance, depending on the distance level to which the distance information belongs, If the distance information falls within the connection area level, the light transmittance of the dimmable glass is adjusted to the light transmittance of the connection area. If the distance information falls within the level of the welcome area, the light transmittance of the dimmable glass is adjusted to the light transmittance of the welcome area. The process includes, if the distance information falls within the unlocked area level, adjusting the light transmittance of the dimmable glass to the light transmittance of the unlocked area.

[0067] In a specific implementation, the second distance range includes multiple levels of connection area level, welcome area level, and unlock area level, where the distance from the vehicle outside the vehicle gradually decreases. Referring to Figure 5, which shows a schematic diagram of the distance level distribution, the area around the vehicle is divided into connection area, welcome area, and unlock area according to its diameter, as shown in Figure 5. As an example, the range from 10 to 15 m from the vehicle is determined as the connection area, the range from 5 to 10 m from the vehicle is determined as the welcome area, and the range from 0 to 5 m from the vehicle is determined as the unlock area. The multiple distance levels of the second distance range include multiple levels of connection area level, welcome area level, and unlock area level, where the distance from the vehicle gradually decreases. Each distance level corresponds to one light transmittance level.

[0068] Therefore, the multi-stage light transmittance includes a plurality of light transmittances, which gradually increase, for the connection area, the welcome area, and the unlock area. Since the connection area is further from the vehicle than the welcome area, the light transmittance of the connection area is greater than or equal to the light transmittance of the welcome area, and since the welcome area is further from the vehicle than the unlock area, the light transmittance of the welcome area is lower than the light transmittance of the unlock area.

[0069] Referring to Figure 6, which shows a flowchart of the steps for determining the distance level, as shown in Figure 6, if the target object is a digital key, first it is determined whether the digital key has established a connection with the vehicle. If the digital key has not established a connection with the vehicle, it is determined that the target object (digital key) is in a third distance range outside the vehicle, and the light transmittance of the vehicle's tinted glass can be maintained at the current light transmittance (e.g., third light transmittance).

[0070] As shown in Figure 6, after the digital key establishes a connection with the vehicle, the distance between the vehicle and the digital key (target object) is determined based on the acquired distance information. If the distance information determines that the current distance level of the target object is at the connection area level, the light transmittance of the dimmable glass is adjusted to the light transmittance of the connection area. If the distance information determines that the current distance level of the target object is at the welcome area level, the light transmittance of the dimmable glass is adjusted from the light transmittance of the connection area to the light transmittance of the welcome area. If the distance information determines that the current distance level of the target object is at the unlock area level, the light transmittance of the dimmable glass is adjusted from the light transmittance of the welcome area to the light transmittance of the unlock area. As the target object approaches the vehicle, the light transmittance should be adjusted to a higher level, and the light transmittance should be gradually increased so that the target object can acquire information inside the vehicle.

[0071] In one possible embodiment, the method is The method further includes, before acquiring distance information between the target object and the vehicle, maintaining the light transmittance of the vehicle's tinted glass at its initial light transmittance, The aforementioned method, If the door of the vehicle is opened, the steps include adjusting the light transmittance of the dimmable glass to the initial light transmittance, and / or If the door of the vehicle is opened, the method further includes sending an off command to the ambient lights and / or welcome lights of the vehicle.

[0072] In a specific implementation, the light transmittance of the vehicle's tinted glass is maintained at its initial light transmittance before acquiring distance information between the target object and the vehicle. If the vehicle cannot acquire distance information before acquiring distance information between the target object and the vehicle, it indicates that the distance between the target object and the vehicle is too far, and the light transmittance of the tinted glass is maintained at its initial light transmittance. Generally, the initial light transmittance is relatively low and serves to protect the privacy of the car owner. In actual use, the initial light transmittance may be set by the user. Optionally, the initial light transmittance may be the minimum light transmittance.

[0073] When it is detected that a door has been opened, the light transmittance of the dimmable glass is automatically adjusted to the initial light transmittance. When the door is opened, the target can directly observe the situation inside the vehicle without using the dimmable glass, and the light transmittance of the dimmable glass can be automatically adjusted to the initial light transmittance. Furthermore, when the vehicle is outdoors, the glass can be switched to a blackout state based on the privacy protection settings, or to a corresponding light-transmitting / semi-transmitting / blackout state based on the settings of the car owner. In this embodiment, when it is detected that a door has been opened, it is also possible to control the vehicle's ambient lights and / or welcome lights by automatically sending an off command to turn them off.

[0074] In one possible embodiment, the method is The steps include detecting whether the vehicle is connected to a target network permitted by the target object, The further step includes, if it is detected that the vehicle is connected to the target network, adjusting the dimmable glass to a fully transparent state.

[0075] In a specific implementation, it is also possible to detect whether the vehicle is connected to a target network authorized by the target object. The target object may be a home gateway, and if the vehicle is connected to a target network authorized by the home gateway, it indicates that the vehicle has entered the target network's coverage, for example, the vehicle has entered the garage area of ​​the house. Since the garage area is a private area, shading settings are not necessary, so the dimmable glass can be adjusted to a fully transparent state to make it easier to observe the situation inside the car.

[0076] In this embodiment, it is possible to determine whether a vehicle is in a specific environment (e.g., a home environment) by detecting whether or not the vehicle is connected to a target network. Generally, when a smart car key is near a vehicle, the vehicle activates corresponding functions (e.g., welcome, engine start, seat heating, unlock, etc.). However, vehicles are in motion and are in different environments over time, and the requirements for insensitive operation of the vehicle differ in various environments. For example, in a home environment, the target object (e.g., a digital key) is at home and is likely to always be within a valid connection range from the vehicle. In this case, the target object may trigger the vehicle to perform operations such as welcome or unlock. When the vehicle is in a company or other environment, the target object (e.g., a digital key) is at a considerable distance from the vehicle. Typically, the target object is not within the vehicle's valid connection area, and operations such as welcome or unlock are not triggered. In this embodiment, we propose to determine whether a vehicle is in a specific environment (e.g., a home environment) by detecting whether or not the vehicle is connected to a target network. When the vehicle is in a specific environment, the dimmable glass can be directly adjusted to a fully transparent state, and the rules for the vehicle's insensitive operation can be controlled so that when the vehicle is in a home environment, the distance between the target object and the vehicle is always within a valid connection range, and the vehicle avoids continuously turning on corresponding functions (e.g., welcome, engine start, seat heating, unlock, etc.). This allows the vehicle's insensitive operation to better match the requirements of a specific environment, improving the user experience.

[0077] In one possible embodiment, the method is If the frequency with which the distance information triggers light transmittance adjustment is greater than a target threshold, the further step includes maintaining the light transmittance of the vehicle's dimmable glass at its current light transmittance.

[0078] In specific implementations, when distance detection is rapidly adjusted for sensing accuracy, or when the target's position changes frequently, causing distance information to change frequently, the frequency of light transmittance adjustments can be detected to avoid frequent adjustments and reduce power consumption. If the frequency of light transmittance adjustments is greater than the target threshold, it means that the vehicle's light transmittance is being adjusted too often. In this case, the light transmittance of the vehicle's tinted glass can be maintained at its current level, thereby fixing the light transmittance and reducing power consumption caused by frequent adjustments.

[0079] In one possible embodiment, the step of adjusting the light transmittance of the vehicle's dimmable glass according to the distance information is: The process includes adjusting the light transmittance of one or the side of the dimmable glass of the vehicle that is closest to the target object, according to the distance information.

[0080] Glass installed in a vehicle can be found in various locations, such as the windshield, rear window, sunroof, side windows, and sun visors. When adjusting the light transmittance of dimmable glass according to distance information, all dimmable glass in the vehicle may be adjusted, or one or more dimmable glass may be adjusted. In this embodiment, the light transmittance of the dimmable glass closest to the target can be determined according to distance information. For example, if the target is on the left side of the vehicle, the light transmittance of the two windows on the left side of the vehicle can be increased according to distance information, allowing the target to observe the situation inside the vehicle through these two windows, thus enabling flexible adjustment of the light transmittance of the dimmable glass.

[0081] In one possible embodiment, the step of obtaining distance information between the target object and the vehicle is: If multiple targets exist simultaneously, the procedure includes the step of obtaining distance information between the vehicle and the target with the highest priority among the multiple targets.

[0082] In a specific implementation, multiple targets may exist simultaneously. For example, if the target is a digital key, there may be multiple users each possessing a digital key for a vehicle. In this case, the priority of each target is first determined, the target with the highest priority is designated as the valid target, distance information between that target and the vehicle is obtained, and the light transmittance of the vehicle's tinted glass can be adjusted according to that distance information.

[0083] In one possible embodiment, the method is The further step includes transmitting control commands to the ambient lights and / or welcome lights of the vehicle in accordance with the distance information.

[0084] In a specific implementation, it is also possible to send control commands to the vehicle's ambient lights and / or welcome lights based on distance information, thereby controlling whether the ambient lights and / or welcome lights are turned on or off.

[0085] Ambient lighting, in particular, is interior lighting installed inside a vehicle to enhance the atmosphere in the cockpit. It is typically installed on door panels, the roof, cup holders, central controls, welcome pedals, and the trunk. With technological advancements, ambient lighting displays have become more personalized and diverse. They come in various forms, including single-color, multi-color, breathing rhythms, and musical rhythms. Ambient lighting can be controlled via apps, voice, gestures, or automatically adjusted according to the passenger's various emotions. Furthermore, ambient lighting can also be used to display vehicle status, such as vehicle malfunction information. Welcome lights refer to the lights located below the vehicle doors. Typically, when the door is opened, the welcome lights instantly illuminate the ground and the path in front of the door for the passenger, and immediately turn off when the door is closed.

[0086] In a specific implementation, the vehicle's smart cockpit system can be used to acquire distance information. Based on this distance information, the smart cockpit system sends control commands corresponding to ambient lights and / or welcome lights through a standard control interface, and turns the ambient lights and / or welcome lights on or off according to those control commands.

[0087] Normally, when a door is detected to be opened, the welcome lights automatically turn on, and the ambient lights must be manually turned on by the user using the corresponding button in the cockpit. In the embodiments of the present invention, the distance between the target object and the vehicle can be determined based on the acquired distance information between the target object and the vehicle, and the ambient lights and / or welcome lights can be automatically turned on or off depending on the distance between them. The user does not need to manually turn on the ambient lights, and the welcome lights can also be turned on in advance before the door is opened, thus improving the user experience.

[0088] In one possible embodiment, referring to Figure 7, which is a flowchart of the steps of sending a control command, the steps of sending a control command to the ambient lights and / or welcome lights of the vehicle in accordance with distance information, as shown in Figure 7, The process includes the step of sending an ON command to the vehicle's ambient lights and / or welcome lights if the distance information falls within the welcome area level. In a specific implementation, when a target approaches the vehicle, distance information between the target and the vehicle is acquired. As shown in Figure 7, if the distance information determines that the target is within the welcome area, the vehicle's smart cockpit system sends an ON command to the vehicle's ambient lights and / or welcome lights, illuminating the road in front of the target's door. In a parking lot application scenario, pre-turning on the ambient lights and / or welcome lights makes it easier for the user to quickly find the desired vehicle, and an input signal can be sent to the dimmable glass to control it and adjust the light transmittance to the light transmittance of the welcome area.

[0089] If the distance information indicates that the target is inside the vehicle, an off command is sent to the vehicle's ambient lights and / or welcome lights. Or, If the distance information indicates that the target is inside the vehicle, an initial state restore command is sent to the vehicle's ambient lights and / or welcome lights.

[0090] In a specific implementation, as shown in Figure 7, if the system determines that the target is inside the vehicle based on distance information, an off command can be sent to the vehicle's ambient lights and / or welcome lights, automatically turning them off. After the target enters the vehicle, there is no need to illuminate the exterior and interior with the welcome lights and ambient lights; the system can automatically send an off command based on the target's distance information, turning off the ambient lights and / or welcome lights. Alternatively, if the system determines that the target is inside the vehicle based on distance information, an initial state command can be sent to the ambient lights and / or welcome lights to restore them to their initial state, and an input signal can be sent to the dimmable glass to control it and adjust its light transmittance to a third light transmittance.

[0091] Furthermore, multiple areas with different distance levels, such as a welcome area and an unlock area, can be set within different radius areas around the vehicle. When a user enters a different area, the vehicle can determine the user's intention to use the vehicle and perform actions such as welcoming or unlocking. For example, when a user approaches the vehicle and enters the welcome area, the vehicle identifies the user's identity and automatically turns on the welcome lights. When a user enters the unlock area, the vehicle automatically unlocks and adjusts the seat to the user's preferred position. In addition, pressure sensors installed in the seat can determine whether or not a target is inside the vehicle. If the user is inside the vehicle, ambient lighting can be controlled via the app, voice, gestures, etc., or the ambient lighting can be automatically adjusted according to the target's various emotions.

[0092] In one possible embodiment, the step of sending an ON command to the ambient lights and / or welcome lights of the vehicle is: Steps to acquire ambient light brightness information, If the brightness of the ambient light is higher than a preset brightness threshold, the step of sending a flashing-on command to the vehicle's welcome lights, The method includes the step of sending a command to the vehicle's welcome lights to keep them constantly lit if the brightness of the ambient light is lower than a preset brightness threshold.

[0093] In a specific implementation, ambient light brightness information is acquired through sensors corresponding to the vehicle's smart cockpit system, and based on this ambient light brightness information, it is possible to determine whether the current ambient light brightness is lower than a preset brightness threshold. If the ambient light brightness is higher than the preset brightness threshold (for example, outdoors during the day), it means that the current environment is sufficiently bright and the lighting effect of the welcome lights is not sufficiently apparent. Therefore, a flashing ON command can be sent to the vehicle's welcome lights to keep them flashing. If the ambient light brightness is lower than the preset brightness threshold (for example, outdoors at night), it means that the current environment is relatively dark. A constant illumination ON command can be sent to the vehicle's welcome lights to keep them constantly illuminated and ensure the lighting effect.
