[0002] In more and more scenarios, the driver or passenger in a vehicle needs to show a two-dimensional code (such as a payment code or a health code) to the outside, and the driver or passenger often needs to open the window for a long time during the process of showing the two-dimensional code. When the weather is bad outside, or in the context of the epidemic, opening the window for a long time may affect the comfort of the driver or passenger, and even lack a certain safety. SUMMARY

[0003] The embodiments of the present application provide a method and device for controlling display and a mobile carrier, which can display information to the outside through the window, realize contactless information verification, and help improve the comfort and safety of the driver or passenger.

[0004] The mobile carrier in the present application can include a road vehicle, a water vehicle, an air vehicle, an industrial device, an agricultural device, or an entertainment device, etc. For example, the mobile carrier can be a vehicle, which is a general concept of a vehicle, and can be a vehicle (such as a commercial vehicle, a passenger vehicle, a motorcycle, a flying vehicle, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), an agricultural device (such as a mower, a harvester, etc.), an entertainment device, a toy vehicle, etc. The embodiments of the present application do not specifically limit the type of vehicle. For another example, the mobile carrier can be an airplane or a ship.

[0005] In a first aspect, a method for controlling display is provided, which includes: generating first image information according to received first instructions and identity information of a first user in a cockpit of a vehicle; and controlling a first window of the vehicle to display the first image information.

[0006] Exemplarily, the first image information is used for verification by a machine or a person outside the vehicle.

[0007] In the technical solution, the vehicle window can be used as a medium to display information externally, and contactless information verification is achieved, which helps to improve the comfort and safety of the driver and passengers. In a scenario, when the epidemic is more serious, a negative pressure environment is maintained in the cabin, or the exchange of air in the cabin and the air outside is minimized, which can significantly reduce the risk of epidemic transmission. Based on the above technical solution, contactless first image information verification is achieved without opening the window, which can effectively protect the health and safety of the driver and passengers in the cabin and / or the health and safety of the staff outside the cabin. In another scenario, the external environment of the vehicle is harsh, for example, there is a lot of wind and sand, or the temperature is too high or too low, or it is raining or snowing. If the window is opened for a long time, the wind and sand outside may enter the cabin, or the air with unsuitable temperature outside may enter the cabin, or rain or snow may enter the cabin. In any of the above cases, the comfort of the driver and passengers will be affected. Based on the above technical solution, contactless first image information verification is achieved without opening the window, which can effectively protect the comfort of the driver and passengers in the cabin.

Exemplarily, the physical function key can be a dial lever, or a button, or another physical function key.

[0009] With reference to the first aspect, in some implementations of the first aspect, the first image information includes a two-dimensional code image.

[0010] With reference to the first aspect, in some implementations of the first aspect, the control of the first window of the vehicle to display the first image information includes: controlling the first window to display the first image information according to a first position of the first user in the cabin, the first position corresponding to the first window.

[0011] In the technical solution, the display position of the first image information can be adaptively adjusted according to the position of the first user in the cabin. When there are multiple users in the vehicle, the personnel or equipment outside the vehicle can clearly know which user the image information on the window corresponds to.

[0012] With reference to the first aspect, in some implementations of the first aspect, the control of the first window of the vehicle to display the first image information includes: controlling the first window to display the first image information according to a second position of a device that detects or recognizes the first image information, the second position corresponding to the first window.

[0013] Exemplarily, the device detecting or recognizing the first image can be a handheld device of an off-vehicle person; or can also be a device automatically detecting or recognizing the first image information, for example, a device recognizing or detecting a two-dimensional code arranged at a barrier lever support of a barrier gate.

[0014] Exemplarily, if the device is arranged at the left side of the vehicle, the first image information is displayed through at least one of the left side windows of the vehicle; if the device is arranged at the right side of the vehicle, the first image information is displayed through at least one of the right side windows of the vehicle; if the device is arranged at the front of the vehicle, the first image information is displayed through the front windshield of the vehicle.

[0015] In some possible implementation manners, the first window can also be controlled to display the first image information according to a position of a person detecting or recognizing the first image information, the position corresponding to the first window.

[0016] In some possible implementation manners, the first window can be controlled to display the first image information according to a first position of the first user in the cabin and a second position of a device detecting or recognizing the first image information. Exemplarily,

[0017] In the above technical solution, the first image information is displayed through the window on the side of the device or the person detecting or recognizing the first image information, which helps to improve the verification efficiency of the first image information and further improve the passing efficiency.

[0022] In some possible implementation manners, the position of the first window and / or the content of the first image information can be prompted in a voice broadcast manner. For example, the first image information includes a payment code, and when the first image information is displayed on the left front window (the first window), the position of the first window and the content of the first image information can be prompted in a voice "please scan the left front window payment code for collection".

[0023] In the technical solution described above, when the first image information is verified or identified, the out-of-vehicle staff or device can not know the function and / or position of the two-dimensional code, and therefore the out-of-vehicle staff can be prompted in a text or voice prompt manner to scan the two-dimensional code, thereby improving the communication efficiency between inside and outside the vehicle and the verification efficiency of the first image information.

Further, when the first input is a physical function key input, the window on which the image information is displayed is determined according to the direction in which the dial lever is dialed. For example, the image information includes the first image information.

In some possible implementation manners, the vehicle 100 can also perform voice interaction with the user through other external devices, such as a Bluetooth headset, and the present application does not make a specific limitation in this regard.

[0059] The display device 130 in the cabin is mainly divided into two categories, the first category is a vehicle display screen; the second category is a projection display screen, for example, a head up display (HUD), through which projection display can be performed on the vehicle window. The vehicle display screen is a physical display screen, and is an important component of the in-vehicle infotainment system. Multiple display screens can be provided in the cabin, such as a digital instrument display screen, a central control screen, a display screen in front of a passenger (also referred to as a front passenger) at a co-driver position, a display screen in front of a left rear passenger, and a display screen in front of a right rear passenger. The head up display is also referred to as a head-up display system. For example, used for displaying driving information such as speed, navigation, etc. on a display device (such as a windshield glass) in front of a driver. To reduce the time of visual line shift of the driver, avoid pupil changes caused by visual line shift of the driver, and improve driving safety and comfort. The HUD includes, for example, a combiner-HUD (C-HUD) system, a windshield-HUD (W-HUD) system, and an augmented reality HUD (AR-HUD).

[0060] Some or all functions of the vehicle 100 can be controlled by the computing platform 150. The computing platform 150 can include one or more processors, such as processors 151 through 15n (n being a positive integer), which are circuits having a processing capability for signals. In one implementation, the processors can be circuits having an instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a kind of microprocessor), a digital signal processor (DSP), and the like. In another implementation, the processors can be circuits having a certain function implemented by a fixed or reconfigurable logic relationship of hardware circuits, such as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD) implemented hardware circuit, such as a field programmable gate array (FPGA). In the reconfigurable hardware circuit, the processor loads a configuration document to implement the hardware circuit configuration, which can be understood as the process of the processor loading instructions to implement the functions of the above part or all units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as a kind of ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), and the like. In addition, the computing platform 150 can further include a memory for storing instructions, and some or all of the processors 151 through 15n can call the instructions in the memory and execute the instructions to implement corresponding functions.

[0061] In the embodiments of the present application, the processor can process the vehicle surrounding environment information obtained from the perception system 120, or the processor can process the voice information of the driver and passenger obtained from the perception system 120, and determine to acquire the two-dimensional code information and generate the two-dimensional code. Further, the processor can also control the two-dimensional code to be displayed on the vehicle window. In some possible implementation manners, the above two-dimensional code information and two-dimensional code can also be stored in the memory in the computing platform 150 in the form of data.

[0062] It should be understood that the above operations can be performed by the same processor, or can also be performed by multiple processors, and the embodiments of the present application do not make specific limitations.

[0063] It should be understood that the above components are only an example, and in the specific implementation process, the components in each module can be added or deleted according to actual needs, Figure 1 It should not be understood as a limitation on the embodiments of the present application.

[0064] Figure 2 A schematic diagram of a vehicle cabin scene is provided in the embodiments of the present application. One or more cameras can be installed inside or outside the intelligent cabin to capture images inside or outside the cabin, for example, the camera of the driver monitoring system (DMS), the camera of the cabin monitoring system (CMS), and the camera of the dashcam, Figure 2 Take the camera arranged at the A-pillar as an example. The camera for capturing images inside and outside the cabin can be the same camera or different cameras.

It should be understood that the position of the camera for collecting image information in the cabin in the embodiments of the present application is not specifically limited. The camera can be located Figure 2 as shown in the A-pillar, or below the steering wheel, or on the B-pillar, or near the rearview mirror, etc.

[0065] As described above, in more and more scenarios, the driver and passenger in the vehicle need to display a two-dimensional code (such as a payment code or a health code) to the outside. In the process of displaying the two-dimensional code by the driver and passenger, the vehicle window needs to be opened for a long time. In poor weather outside, or in the context of the epidemic, opening the window for a long time may affect the comfort of the driver and passenger, and even lack a certain safety. In particular, when the cabin of the vehicle needs to maintain a negative pressure environment, the window cannot be opened to display information such as a two-dimensional code. In view of this, the embodiments of the present application provide a method, device and mobile carrier for controlling display, which can use the vehicle window as a medium to display two-dimensional code information, realize contactless two-dimensional code verification, and help to improve the comfort and safety of the driver and passenger.

[0066] Figure 3 A schematic diagram of a system framework for controlling display is shown in the embodiments of the present application. As Figure 3As shown, the system includes a perception module, a two-dimensional code generation module, an optical projection module, a display module, and a payment code generator, a health code generator, and an account application device. Among them, the perception module sends the obtained instructions or information to the two-dimensional code generation module to trigger it to generate a two-dimensional code. Exemplarily, the two-dimensional code generation module obtains two-dimensional code information from at least one of the payment code generator, the health code generator, and the account application device according to the instructions or information obtained from the perception module, and then generates a two-dimensional code and sends it to the optical projection module. The optical projection module projects the two-dimensional code into the display module, such as the front windshield, the rear windshield, the driver's side window (also known as the left front window), the passenger's side window (also known as the right front window), the second row left side window (also known as the left rear window), the second row right side window (also known as the right rear window), etc. In an example, the perception module can include Figure 1 As shown in the perception system 120, the perception module can include a sound sensor, and the instructions obtained by the perception module can include voice instructions in the cabin of the vehicle; or the perception module can include a touch screen sensor, and the instructions obtained by the perception module can include Figure 2 As shown, the vehicle display screen or the human machine interface (HMI) detects a click signal; or the perception module can include a physical function key, and the instructions obtained by the perception module can include a signal detected by the physical function key, such as a steering wheel dial signal. In some possible implementations, the perception module can include Figure 1 As shown, the perception system 120 includes one or more cameras, and then the camera obtains an image and sends it to the two-dimensional code generation device. The two-dimensional code generation device performs text recognition on the picture to obtain the instruction "please show the two-dimensional code". In another example, the two-dimensional code generation module can include Figure 1 As shown, the one or more processors in the computing platform 150, the optical projection module can include Figure 1 As shown, the one or more processors in the computing platform 150, the display module can also include Figure 1 As shown, the one or more display devices in the display device 130.

[0067] It should be understood that the above-mentioned modules and devices are only one example, and in actual application, the above-mentioned modules and devices can be added or deleted according to actual needs.

[0068] Figure 4 A schematic flowchart of a method for controlling display provided by an embodiment of the present application is shown. The method 400 can be applied to Figure 1 As shown in the vehicle 100 or Figure 2 As shown in the cabin, the method can also be executed by Figure 3 As shown, the system. The method includes:

[0069] S410, generate first image information according to the received first instruction and identity information of the first user in the cabin of the vehicle.

[0070] Exemplarily, the vehicle can include the vehicle 100 in the above-mentioned embodiments. The first user can be a primary driver or a user at another position in the cabin of the vehicle. The identity information can include, but is not limited to, biometric information stored in the vehicle, and an account, etc. The biometric information can include, but is not limited to, fingerprint, palmprint, voice information, face information, iris information, gait information, etc. The account can include account information for logging into a vehicle system, etc. The first image information can include a two-dimensional code (such as a payment code, a health code) associated with the first user; or can also include other images or information that need to be displayed to machines or personnel outside the vehicle, such as relevant access certificates, etc.; or the first image information can also include an interface image containing a two-dimensional code, for example, an interface containing a health code that pops up on a mobile terminal after the first user scans a site code using the mobile terminal.

[0071] In some possible implementations, the identity information of one or more users is stored in the vehicle, and if the identity information of the first user matches the identity information of the one or more users, the first image information can be generated according to the received first instruction and the identity information of the first user.

[0072] Exemplarily, the first instruction can include, but is not limited to, a voice instruction, an instruction generated according to an input to a vehicle screen, an instruction generated according to an operation on a physical function key (such as a dial lever, a button, etc.), and an instruction generated according to an image recognition result.

[0073] Firstly, a voice instruction of a user, for example, the vehicle can acquire audio of the voice instruction through a sound sensor, and analyze the voice semantics of "please display the first image information" through a processing device.

[0074] Secondly, an instruction generated according to an input to a vehicle screen, for example, when the vehicle screen is in a main desktop page, a right sliding signal on the screen of an electronic device is detected by a touch sensor, and then an instruction for controlling the vehicle to generate the first image information is generated according to the right sliding signal.

[0075] Thirdly, an instruction generated according to an operation on a physical function key, for example, when a pressing signal is collected by a pressure sensor at a dial lever of the vehicle, a processing device (such as a processor) of the vehicle can process the pressing signal and perform corresponding control, for example, the processing device of the vehicle can generate an instruction for controlling the vehicle to generate the first image information according to the pressing signal.

[0076] Fourthly, the instruction generated according to the image recognition result, for example, the vehicle's camera shoots the flat of the vehicle's surrounding environment, the image is recognized by the processing device, the text information of "please display the first image information" is obtained, and then the instruction of controlling the vehicle to generate the first image information is generated according to the text information.

[0077] S420, the first window of the vehicle displays the first image information.

[0078] Exemplarily, the first window can include at least one of the front windshield, the left front window, the right front window, the left rear window, and the right rear window.

[0079] Optionally, the first window displays the first image information according to the first position of the first user in the cabin corresponding to the first window.

[0080] Exemplarily, "the first position corresponding to the first window" can include: the first position can be a main driving position, and the first window can be the window at the main driving position and / or the front windshield in the above-mentioned embodiments, that is, the main driving position corresponds to the window at the main driving position; the first position can be a co-driver position, and the first window can be the window at the co-driver position and / or the front windshield in the above-mentioned embodiments, that is, the co-driver position corresponds to the window at the co-driver position; the first position can be a second-row left position of the vehicle, and the first window can be the second-row left window in the above-mentioned embodiments, that is, the second-row left position corresponds to the second-row left window; the first position can be a second-row right position of the vehicle, and the first window can be the second-row right window in the above-mentioned embodiments, that is, the second-row right position corresponds to the second-row right window.

[0081] Exemplarily, the method for determining the first position of the first user in the cabin includes but is not limited to: determining the first position of the first user by a sound wave sensor; determining the first position of the first user by a camera or an in-cabin visual sensor; determining the first position of the first user by a pressure sensor arranged at a seat.

[0082] Exemplarily, the vehicle can determine the actual position of the first user in the cabin according to the audio information obtained by the sound wave sensor. The audio information can be obtained by excluding various invalid audio information from the collected audio information in the vehicle, and the invalid audio information can be audio information with too low volume. The sound source position can be the position of the sound source corresponding to the audio information, which can be the relative position of the vehicle screen based on the sound source positioning, or a specific position coordinate.

[0083] Exemplarily, the position of the sound source can be determined based on the audio information collected by multiple sound wave sensors according to the time difference of arrival (TDOA) principle. For example, sound wave sensors A and B respectively detect that audio is emitted from the sound source S, where the time at which the sound source signal of the sound source S arrives at the sound wave sensor A is t1, and the time at which the sound source signal of the sound source S arrives at the sound wave sensor B is t2, then the time difference dt = |t1-t2|, assuming that the distance between the sound source S and the sound wave sensor A is AS, the distance between the sound source S and the sound wave sensor B is BS, and the speed of sound is c, then dt = t1-t2 = AS / c-BS / c can be obtained, and then the position of the sound source can be determined according to the distance a between the two sound wave sensors and by selecting one of the sensors as a reference point.

[0084] Exemplarily, the first position of the first user is determined by a camera or an in-cabin visual sensor, specifically, the facial information of the user obtained by the camera or the in-cabin visual sensor is used to determine the actual position of the user in the cabin. The camera or the in-cabin visual sensor includes but is not limited to a camera sensor integrated or installed on a vehicle screen or a camera sensor installed inside a vehicle cabin, for example, a red green blue (RGB) camera, a red green blue-infrared radiation (RGB-IR) camera, or a time of flight (TOF) camera.

[0085] In some possible implementations, whether a user is seated at a seat can also be detected by a laser radar integrated or installed on a vehicle screen or a laser radar installed inside a vehicle cabin, a radio transceiver (including but not limited to a millimeter wave radar or a centimeter wave radar) on a vehicle screen or at the edge of a vehicle screen, an infrared sensing device (including but not limited to an infrared range finder or a laser range finder) integrated on a vehicle screen or at the edge of a vehicle screen, an eye tracker, and the like, and then the actual position of the user in the cabin is determined.

[0086] Exemplarily, the first position of the first user is determined by a pressure sensor arranged at a seat, specifically, when the pressure at a seat is greater than or equal to a preset threshold, it is determined that a user is seated at the seat. Exemplarily, the preset threshold can be 100 Newton (N), or 200 N, or other values.

[0087] Optionally, the first window displays the first image information according to a second position of a device for detecting or identifying the first image information, and the second position corresponds to the first window.

[0088] Exemplarily, when the second position is a position in front of the vehicle, the first window can be the front windshield; when the second position is a position on the left side of the vehicle, the first window can be the driver-side window and / or the second-row left-side window; when the second position is a position on the right side of the vehicle, the first window can be the passenger-side window and / or the second-row right-side window.

[0089] In some possible implementation manners, the first window is controlled to display the first image according to a first position of the first user in the cabin and a second position of the device detecting or recognizing the first image information. In an example, when the first position is the driver position, it is preliminarily determined to display the first image on the front windshield and / or the left front window. Further, when the second position is a position on the left side of the vehicle, it is determined to display the first image on the left front window, i.e., the first window is the left front window.

[0090] Optionally, the first window of the vehicle displays the first image information, including: controlling a first area of the first window to display the first image information, the first area corresponding to a third position of the first user in the cabin.

[0091] Exemplarily, the first window includes the front windshield, and the front windshield can include a first area, a second area and a third area. The first area is a left-side area of the front windshield, corresponding to the driver position; the second area is a right-side area of the front windshield, corresponding to the passenger position; and the third area is a middle area of the front windshield, corresponding to the rear-row position.

[0092] It should be understood that the above-mentioned correspondence between the "position" and the "first window" or the "first area of the first window" is only exemplary, and the correspondence between them can be in other forms in the specific implementation process.

[0093] Optionally, the control of the first window of the vehicle to display the first image information includes: controlling the first image information to be displayed on the first window by the HUD.

[0094] In some possible implementation manners, the first image information can be displayed on the first vehicle window by a thin film transistor liquid crystal display (TFT) technology, that is, information is projected after light emitted by a light emitting diode (LED) passes through a liquid crystal unit; or the first image information can be displayed on the first vehicle window by a digital light processing (DLP) technology; or the first image information can be projected on the first vehicle window by using a laser scanning micro-electro-mechanical system (MEMS) projection system, where the laser scanning MEMS projection system takes a red, green and blue (RGB) single-color laser with high power as a light source, and the laser is projected on a display screen after being integrated and scanned by corresponding optical elements and processing chips.

[0095] Optionally, after the first vehicle window is controlled to display the first image information, a position of the first vehicle window and / or content of the first image information is prompted.

[0096] Optionally, in response to the first input of the first user, the first vehicle window is controlled to switch to a second vehicle window of the vehicle to display the first image information.

[0097] For example, the first input can be a voice instruction input, or a voice instruction input by a physical function key, or an input to a vehicle-mounted screen.

[0098] For example, the second vehicle window can include at least one vehicle window different from the first vehicle window in a front windshield, a rear windshield, a driver's seat vehicle window, a front passenger seat vehicle window, a rear left vehicle window of the cabin, and a rear right vehicle window of the cabin.

[0099] The method for controlling display provided in the embodiments of the present application can display information externally by taking a vehicle window as a medium, implement contactless information verification, and help improve the comfort and safety of a driver and a passenger.

[0100] The following will be described in detail Figures 5 to 7 The method 400 will be described in detail in different application examples.

[0101] In an example, when a vehicle wants to enter a certain community or a certain parking lot, the vehicle can be prompted to display a QR code on a vehicle window, and a user can scan the QR code by using a mobile phone to verify information of the vehicle. Figure 5As shown in (a), when a vehicle approaches a barrier gate (or vehicle stop), the gate arm support displays "Please show your health code" as shown in 501. The vehicle can then use a camera to capture images of its exterior and extract the "Please show your health code" message from the captured images. Based on the identity information of the first user in the vehicle, the vehicle can then obtain the first user's health code information. Alternatively, after seeing the content shown in 501, the first user can issue a voice command, "Please display your health code on the windshield." Upon receiving the voice command, the vehicle can then obtain the first user's health code information based on their identity information.

[0102] In another example, when a vehicle is about to leave a parking lot, such as Figure 5 As shown in (b), when a vehicle approaches the barrier gate (or parking barrier), the gate arm bracket displays the message "You have been parked for 6 hours and 22 minutes, a payment of 21 yuan is required. Please show your payment code." The vehicle can then use a camera to capture images of its exterior and extract the "Please show your payment code" message. Based on the identity information of the first user in the vehicle, the vehicle can then retrieve the first user's payment code. Alternatively, after seeing the message displayed in image (502), the first user can issue a voice command, "Please display the payment code on the windshield." Upon receiving the voice command, the vehicle can then retrieve the first user's payment code based on their identity information.

[0103] For example, if the first user's health code information or payment code information is stored in the vehicle, the vehicle can search for and determine the first user's health code information or payment code information in the vehicle based on the first user's identity information; or, if the first user's health code information or payment code information is stored in the first user's mobile terminal, the vehicle can obtain the first user's health code information or payment code information from the first user's mobile terminal based on the first user's identity information.

[0104] For example, before obtaining the first user's health code or payment code information based on the first user's identity information, the first user's identity information can be verified first. For instance, the first user's identity can be identified based on voice commands or captured facial images.

[0105] Furthermore, the vehicle control displays the first image information generated based on the first user's health code information or payment code information on the first vehicle window.

[0106] In one example, the vehicle controls the display of a first image on the windshield, for example, in the area of ​​the windshield corresponding to the driver's side. This first image information can be displayed in response to a "Please show payment code" instruction, such as... Figure 6The (a) in FIG. 6A shows the view angle in the vehicle cabin, and the first image information can include the payment code 601, or can also include the payment code 601 and the prompt text "Please scan the payment code here" 602. The prompt text is used to prompt the person outside the vehicle that the two-dimensional code displayed on the vehicle window is a payment code. Figure 6 The (b) in FIG. 6A shows the view angle outside the vehicle, and the two-dimensional code 603 and the text 604 are the display effects of the payment code 601 and the prompt text 602 in the view angle outside the vehicle.

[0107] In another example, the first image information can be displayed in response to the instruction "Please show the health code", as shown in Figure 6 The (c) in FIG. 6B shows the view angle in the vehicle cabin, and the first image information can include the health code 605, or can also include the health code 605 and the name information of the user to which the health code belongs "*Kai" 606. Figure 6 The (d) in FIG. 6B shows the view angle outside the vehicle, and the two-dimensional code 607 and the text 608 are the display effects of the health code 605 and the text 606 in the view angle outside the vehicle.

[0108] In another example, the first vehicle window displaying the first image information can be determined according to the location of the prompt board. As shown in Figure 6 The (c) in FIG. 6C shows that the prompt board requiring to show the two-dimensional code information or other information required for passing through is located on the left side of the vehicle, and the left front window and / or the left rear window can be controlled to display the first image information.

[0109] In another example, the first vehicle window displaying the first image information can be determined according to the voice instruction of the first user. As shown in Figure 6 The (e) in FIG. 6D shows that the first user includes the user at the driver's seat, and when the voice instruction "Please display the health code on the left front window" issued by the user at the driver's seat is detected, the left front window is controlled to display the first image information, as shown in the (f) in FIG. 6D. Figure 6 Alternatively, the first vehicle window can be determined according to the region where the voice instruction "Please display the two-dimensional code on the vehicle window" is detected. For example, if the voice instruction comes from the driver's area, the vehicle window at the driver's seat (i.e., the left front window in the above embodiment) is determined as the first vehicle window; or if the voice instruction comes from the co-driver's area, the vehicle window at the co-driver's seat (i.e., the right front window in the above embodiment) is determined as the first vehicle window. Further, the first image information is controlled to be displayed on the first vehicle window.

[0110] In another example, when there are two or more users in the vehicle, the first vehicle window can be controlled to display the information of the two or more users. For example, there are users "*Kai", "*Qi", "*Fan", and "*Tian" in the vehicle, which are located at the driver's seat, the co-driver's seat, the right side of the second row, and the left side of the second row, respectively. In some possible implementation manners, as shown inFigure 6 As shown in (g) of FIG. 26, the front windshield is controlled to display the health codes of “*empty”, “*meal”, “*weather”, and “*Qi” in turn. In some possible implementation manners, the two or more users’ information can be displayed on multiple vehicle windows. As shown in (h) of FIG. 26, the health codes of the users located at the driver seat, the front passenger seat, the second-row right seat, and the second-row left seat are displayed on the left front window, the right front window, the right rear window, and the left rear window respectively. Figure 6

[0111] In some possible implementation manners, when there are two or more users in the vehicle, after obtaining the two-dimensional code information of each of the two or more users according to the identity information of the two or more users, a two-dimensional code is synthesized according to the two-dimensional code information of the two or more users, and the vehicle window is controlled to display the two-dimensional code.

[0112] In some possible implementation manners, when there are two or more users in the vehicle, only the two-dimensional code associated with the driver user can be displayed. For example, after generating the two-dimensional code according to the identity information of the driver user, the vehicle window is controlled to display the two-dimensional code.

[0113] In some possible implementation manners, when entering a certain place, a specific two-dimensional code can be scanned by staff or machines for registration (or verification). Exemplarily, the “specific two-dimensional code” is a two-dimensional code specific to the place, which identifies information such as the location and name of the place, and after the user scans the specific two-dimensional code, the information of the person entering or leaving the place can be automatically registered. In some implementations, the “specific two-dimensional code” can be referred to as a “place code”. In the above scenario, after scanning the specific two-dimensional code, a two-dimensional code or other registration code with time information is generated for verification by the machines or staff of the place. In the embodiments of this application, the user in the vehicle scans the specific two-dimensional code using the mobile terminal, and after the mobile terminal generates a two-dimensional code or other registration code with time information, the vehicle can control to display the two-dimensional code or other registration code with time information. As shown in (a) of FIG. 27, the vehicle drives to a barrier (or barrier), and the barrier rod support of the barrier displays “please scan the two-dimensional code” as shown in 701. Further, as shown in (b) of FIG. 27, the user in the vehicle scans the two-dimensional code using the mobile terminal according to the prompt of 701, and jumps to the interface as shown in (c) of FIG. 27. In this embodiment, the interface as shown in (c) of FIG. 27 is a two-dimensional code interface, and the two-dimensional code interface displays the two-dimensional code with time information as shown in 702. Figure 7 Figure 7 Figure 7 Figure 7 ​​​​The interface shown in (c) includes the health code 702, the user's name information (null) 703, the health code status information (green code) 704, the time information (xxxx.xx.xx xx:xx:xx) 705, and the place name information (xx mall) 706. Further, the mobile terminal sends the information contained in the interface to the vehicle. Further, as shown in (d), the vehicle controls the display of the health code shown in 702 on the vehicle window. In some possible implementations, the vehicle can also control the display of the interface shown in (c) on the vehicle window. Figure 7 The interface shown in (c) includes the health code 702, the user's name information (null) 703, the health code status information (green code) 704, the time information (xxxx.xx.xx xx:xx:xx) 705, and the place name information (xx mall) 706. Further, the mobile terminal sends the information contained in the interface to the vehicle. Further, as shown in (d), the vehicle controls the display of the health code shown in 702 on the vehicle window. In some possible implementations, the vehicle can also control the display of the interface shown in (c) on the vehicle window. Figure 7 The interface shown in (c) includes the health code 702, the user's name information (null) 703, the health code status information (green code) 704, the time information (xxxx.xx.xx xx:xx:xx) 705, and the place name information (xx mall) 706. Further, the mobile terminal sends the information contained in the interface to the vehicle. Further, as shown in (d), the vehicle controls the display of the health code shown in 702 on the vehicle window. In some possible implementations, the vehicle can also control the display of the interface shown in (c) on the vehicle window.
