[0048] In related technologies, vehicles are gradually changing people's travel experience by becoming increasingly digitalized, intelligent, and connected. In-vehicle interactive devices serve as the vehicle's interface, enabling interaction between passengers and the vehicle. Existing in-vehicle interactive devices typically have displays to facilitate the display of interactive information and anthropomorphic expressions. While displays with rich visuals can enhance the travel experience for passengers, drivers can easily be distracted by the screen, causing their gaze to deviate from the driving direction and creating potential safety hazards.

[0049] To address the aforementioned issues, this application provides an in-vehicle interactive device and its control method. The following description, in conjunction with the accompanying drawings, will illustrate various embodiments of the in-vehicle interactive device and its control method.

[0050] Please refer to Figures 1 to 3 To address the aforementioned problems, an embodiment of the first aspect of this application provides an in-vehicle interactive device 100, which includes a mounting bracket 1, a housing 2, a display module 3, and a driving module. The housing 2 is connected to the mounting bracket 1 and has at least one opening 5; the display module 3 is disposed within the housing 2; the driving module includes a first driving component 41 and a second driving component 42, the first driving component 41 being connected to the display module 3 and the second driving component 42 being connected to the housing 2.

[0051] The vehicle-mounted interactive device 100 has a first display mode and a second display mode. When the vehicle-mounted interactive device 100 is in the first display mode, at least a portion of the display module 3 displays an image at the opening 5. When the vehicle-mounted interactive device 100 switches from the first display mode to the second display mode, the first driving component 41 drives the display module 3 to rotate relative to the housing 2 and / or the second driving component 42 drives the housing 2 to rotate relative to the mounting bracket 1, so that at least a portion of the display module 3 projects a projection beam to the outside of the housing 2 through the opening 5.

[0052] The in-vehicle interactive device 100 provided in this application can be installed on the dashboard assembly. It can be connected to the dashboard assembly through the mounting bracket 1, so that the in-vehicle interactive device 100 can be fixed on the dashboard assembly.

[0053] exist Figure 1 In the illustrated embodiment, the outer shell 2 is spherical, anthropomorphically resembling a head. Of course, to enrich the appearance of the in-vehicle interactive device 100, the outer shell 2 can also be configured with other shapes, such as imitating the shape of an animal or plant. The outer shell 2 has at least one opening 5 for display, the size of which can be adapted to the size of the outer shell 2, so that the user can easily see the content displayed by the display module 3 through the opening 5. Figure 1 In the illustrated embodiment, at least one opening 5 is located in the middle of the housing 2. The display module 3 located in the opening 5 can display images that are anthropomorphized as human faces, and display facial expressions that match the interactive context to enrich the interaction process between the in-vehicle interactive device 100 and the user.

[0054] The display module 3 may include a display screen body 32 based on technologies such as liquid crystal, OLED, and mini LED, through which different images are displayed. The display module 3 may also include a light-emitting device based on projection technology. The light emitted by the light-emitting device can be projected onto the housing 2 for display, and the light emitted by the light-emitting device can also pass through the opening 5 and be projected onto the outside of the housing to display images on structures such as the vehicle roof and windows. Those skilled in the art can select one or more display structures based on different display technologies to form the display module 3 as needed. Images displayed based on different display technologies and images displayed in different positions have varying degrees of attraction to the driver. For example, an image displayed at the opening 5 is more attractive to the driver than an image projected onto the outside of the housing; an image facing the driver is more attractive than an image facing away from the driver. Therefore, appropriate display modes can be switched according to the actual driving scenario, allowing the display module 3 to present different image display effects.

[0055] Those skilled in the art will understand that the display module 3 can display not only the aforementioned anthropomorphic facial expression images, but also vehicle operating information, navigation information, environmental information of the vehicle's driving environment, and response information generated from user interaction. Vehicle operating information may include vehicle speed, fuel consumption, engine speed, etc. Environmental information of the vehicle's driving environment may include road speed limits, traffic light information, etc.

[0056] Please see Figure 4 In addition to the aforementioned display module 3 and drive module 4, the in-vehicle interactive device 100 may also include an image acquisition unit 101, a voice input unit 102, a processing module 103, and a voice output module 104. The processing module 103 is signal-connected to the image acquisition unit 101, voice input unit 102, processing module 103, voice output module 104, display module 3, and drive module 4, respectively. The processing module 103 can also establish a communication connection with an external server to achieve more complex interactions. When the in-vehicle interactive device 100 is applied to a vehicle, the processing module 103 can also be electrically connected to the vehicle's infotainment system module, thereby allowing control of the vehicle's infotainment system module through the in-vehicle interactive device 100. The infotainment system module may include windows, speakers, air conditioning, etc.

[0057] The in-vehicle interactive device 100 can acquire environmental images through the image acquisition unit 101. The processing module 103 can pre-store image processing programs to process the acquired environmental images, enabling voice interaction between the user and the in-vehicle interactive device 100. The image acquisition unit 101 can be a camera 7. The in-vehicle interactive device 100 can emit sound through the voice output module 104, which can be a speaker. The in-vehicle interactive device 100 can acquire audio data through the voice input unit 102. The processing module 103 can pre-store audio processing programs to convert the audio data acquired by the voice input unit 102 into character data, generate voice response information based on the character data, and play the voice response information through the voice output module 104, thereby enabling voice interaction between the user and the in-vehicle interactive device 100. The voice input unit 102 can be a microphone array. The camera 7 can be installed inside the housing 2, at the end of the housing 2 furthest from the mounting bracket 1, to facilitate the camera 7 acquiring image information about the driver's cab. The speakers can be located at opposite ends of the housing 2, and the area in the housing 2 corresponding to the speakers can be anthropomorphized to the shape of a human ear.

[0058] Please see Figure 5The in-vehicle interactive device 100 has a first display mode and a second display mode. The first display mode can be a multimedia display mode, and the second display mode can be a head-up display mode. That is, when the in-vehicle interactive device 100 is in the multimedia display mode, the in-vehicle interactive device 100 can be in a first position, and at least part of the display module 3 displays an image at the opening 5. The displayed image can be directed towards the side of the driver and passengers inside the vehicle, and the driver and passengers inside the vehicle can directly observe the image displayed at the opening on the in-vehicle interactive device 100. When the in-vehicle interactive device 100 switches from multimedia display mode to head-up display mode, the in-vehicle interactive device 100 can be in a second position. The display module 3 can be driven to rotate relative to the housing 2 by the first drive component 41, and / or the housing 2 can be driven to rotate relative to the mounting bracket 1 by the second drive component 42, so that at least part of the display module 3 projects a projection beam onto the outside of the housing 2 through the opening 5. At this time, the light emitted by the display module 3 can be projected onto the vehicle windows, roof, etc., thereby forming a projection image on the vehicle windows, roof, etc. The driver and passengers in the vehicle can indirectly observe the image displayed by the in-vehicle interactive device 100 through the projection image formed on the windows, roof, etc., so that the driver and passengers can browse the projected image while looking at the front of the vehicle.

[0059] In the in-vehicle interactive device 100 provided in this application, by connecting a first driving component 41 to the display module 3, the display module 3 can be moved relative to the housing 2 via the first driving component 41 to adjust the relative position of the display module 3 and the opening 5 located on the housing 2. By connecting a second driving component 42 to the housing 2, the housing 2 can be moved relative to the mounting bracket 1 via the second driving component 42 to adjust the relative position of the opening 5 and the mounting bracket 1. In different states, the in-vehicle interactive device 100 can, through the driving module, enable the display module 3 to display in different ways through the opening 5, avoiding the driver being easily distracted by the images displayed on the display module and reducing driving safety hazards.

[0060] When the in-vehicle interactive device 100 is in multimedia display mode, the display module 3 can directly display the images to be shown to the driver and passengers, who can directly view the images displayed by the display module 3 through the opening 5. When the in-vehicle interactive device 100 is in head-up display mode, since the user views images projected onto other vehicle components, the in-vehicle interactive device 100 pre-reverses the images to be shown to the driver and passengers, allowing them to view the projected images displayed by the display module 3 on other components. In some embodiments, when the in-vehicle interactive device 100 is in a first display mode, the display module 3 is used to display images generated by the in-vehicle interactive device 100; when the in-vehicle interactive device 100 is in a second display mode, the display module 3 is used to display the reversed image of the image generated by the in-vehicle interactive device 100.

[0061] Please see Figure 3 In one embodiment, the display module 3 includes a projection component 31, and a first driving component 41 is connected to the projection component 31. The first driving component 41 is used to drive the projection component 31 to rotate relative to the housing 2.

[0062] The first driving component 41 allows adjustment of the relative position of the projection component 31 and the opening 5, enabling the projection component 31 to emit a beam of light entirely or partially through the opening 5. The relative position of the housing 2 and the mounting bracket 1 can also be adjusted to correct the distortion of the projected image. Furthermore, the direction of the beam emitted by the projection component 31 relative to the mounting bracket 1 can be changed, thereby adjusting the beam's trajectory to different locations such as car windows or the roof for display.

[0063] The housing 2 may include a light-transmitting area. The projection component 31 can be adjusted to be positioned relative to the light-transmitting area via the first driving component 41. The light beam emitted by the projection component 31 is projected onto the light-transmitting area, and the driver and passengers can view the image through the light-transmitting area.

[0064] In one embodiment, the number of openings 5 ​​is at least two, and the at least two openings 5 ​​include a first opening 51 and a second opening 52; when the vehicle interactive device 100 is in the first display mode, the projection component 31 displays an image at the first opening 51, and when the vehicle interactive device 100 is in the second display mode, the projection component 31 projects a projection beam to the outside of the housing 2 through the second opening 52.

[0065] With the first opening 51 and the second opening 52 respectively located on both sides of the mounting bracket 1, without changing the positional relationship between the outer shell 2 and the mounting bracket 1, the projection component 31 can be moved solely by driving the first driving component 41. This allows the light-emitting surface of the projection component 31 to be positioned corresponding to either the first opening 51 or the second opening 52, thereby enabling the display of an image at the first opening 51 and the projection of a projection beam onto the outside of the outer shell 2 through the second opening 52.

[0066] In one embodiment, the display module 3 further includes a screen 6 disposed in the first opening 51. When the in-vehicle interactive device 100 is in the first display mode, the light-emitting surface of the projection component 31 faces the driver's cab through the first opening 51, and the light beam of the projection component 31 can be projected onto the screen 6 disposed in the first opening 51, allowing the driver and passengers to view the image on the screen 6. When the in-vehicle interactive device 100 is in the second display mode, the light-emitting surface of the projection component 31 projects the light beam onto the windshield through the second opening 52, allowing the driver and passengers to view the projected image on the windshield.

[0067] In one embodiment, the outer shell 2 includes a front shell 21, a rear shell 22, and a top shell 23. The front shell 21 and the rear shell 22 cover each other, and the top shell 23 covers the front shell 21 and the rear shell 22. The top shell 23 is spaced apart from the mounting bracket 1. A first opening 51 is provided in the front shell 21, and a second opening 52 is provided in the rear shell 22. The front shell 21, the rear shell 22, and the top shell 23 can be connected by snap-fit. The first drive assembly 41 can be connected to the rear shell 22. Since the first drive assembly is connected to the outer shell 2, when the second drive assembly 42 pushes the outer shell 2 to move relative to the mounting bracket 1, the first drive assembly 41 and the outer shell 2 move together relative to the mounting bracket 1.

[0068] Please see Figure 6 In some embodiments, the display module 3 further includes a display screen body 32, which is movably connected to the housing 2. The display screen body 32 differs from the projection component 31 in that the beam of light projected by the projection component 31 needs to fall on the surface of an object to display an image, while the display screen body 32 itself can be a self-emissive device to achieve image display. Specifically, the display screen body 32 can be a liquid crystal display, an OLED display, a mini LED display, etc. The display screen body 32 can also be a touch screen with touch functionality. Of course, the display screen body 32 can also be a non-self-emissive device, meaning the projection component 31 can provide a light source for the display screen body 32. Optionally, the display screen body 32 can be a screen. Those skilled in the art do not limit the specific type of the display screen body 32.

[0069] When the vehicle-mounted interactive device 100 is in the first display mode, the display screen 32 is located in the opening 5; when the vehicle-mounted interactive device 100 switches from the first display mode to the second display mode, the display screen 32 is housed in the housing 2, and the first driving component 41 drives the projection component 31 to rotate relative to the housing 2, so that the projection component 31 projects a projection beam to the outside of the housing 2 through the opening 5.

[0070] With only one opening 5 provided, and the light-emitting surfaces of the projection component 31 and the display screen 32 facing the mounting bracket 1 respectively, the display screen 32 can be housed within the housing 2 during the switching process from the first display mode to the second display mode of the vehicle-mounted interactive device 100, thus exposing the opening 5. The first driving component 41 can drive the projection component 31 to move, so that the projection component 31 emits light in the desired direction through the opening 5. For example, this can be used to project images onto the windshield or the roof of the vehicle.

[0071] Since the housing 2 can be configured into any shape as needed, in some embodiments, the display screen 32 is a curved screen adapted to the housing 2, and the display screen 32 can cover the opening 5. The housing 2 and the display screen 32 can be movably connected in various ways.

[0072] For example, a slide rail can be provided on the housing 2, and the display screen 32 can be movably connected to the slide rail. The slide rail can be provided along the major axis or the minor axis of the curved screen.

[0073] For example, the drive module also includes a rotary motor connected to the display body 32. The rotary motor is used to wind the display body to drive the display body 32 to cover or expose the opening. The housing 2 includes a first side and a second side located on both sides of the opening. The first side can be located on the side of the opening 5 closer to the mounting bracket 1, and the second side can be located on the side of the opening 5 away from the mounting bracket 1. The stator of the rotary motor is connected to the housing 2, and the rotor of the rotary motor is configured to cooperate with the stator. One end of the drive shaft of the rotary motor is connected to the rotor, and the other end is connected to the display body 32. When the vehicle interaction device 100 switches to the first display mode, the drive shaft rotates and drives the display body 32 to rotate as well, moving the display body 32 from a first position opposite to the first side to a second position that covers the opening 5. When the vehicle interaction device 100 switches from the first display mode to the second display mode, the drive shaft rotates and drives the display body 32 to rotate as well, moving the display body 32 from the second position to the first position to expose the opening 5, so that the light beam emitted by the projection component 31 can be emitted outward through the opening 5. Optionally, the display body 32 is a flexible, rollable screen.

[0074] For example, the housing 2 has a slide rail, and the display body 32 is movably connected to the slide rail. The drive module 4 also includes a screen driving component connected to the display body 32. The screen driving component is used to drive the display body 32 to move along the slide rail between a first side, a first opening 51, and a second side. The housing 2 includes a first side and a second side located on both sides of the opening 5. The display body 32 includes a main screen and a slider. The screen driving component can push the slider to move, thereby moving the main screen between the first side, the opening 5, and the second side. The screen driving component can be a stepper motor. When the vehicle interaction device 100 switches to the first display mode, the drive shaft of the stepper motor pushes the slider, and the slider drives the display body 32 to move to a second position covering the opening 5. When the vehicle interaction device 100 switches from the first display mode to the second display mode, the drive shaft pushes the slider, and the slider drives the display body 32 to move to a position opposite to the first side or the second side, exposing the opening 5, so that the light beam emitted by the projection component 31 can be emitted outward through the opening 5.

[0075] The number of display screens 32 can be multiple. In the first display mode, multiple display screens 32 can be spliced ​​together to cover the opening 5. In one embodiment, the number of display screens 32 is two, and the two display screens 32 are respectively used to move from the first side and the second side to the opening 5.

[0076] In some embodiments, the mounting bracket 1 includes a main body 11 and at least one mounting ear 12 connected to the main body 11. A second drive assembly 42 is disposed on the main body 11. The mounting ear 12 can be used to connect to the dashboard assembly, and the in-vehicle interactive device can be fixed to the dashboard assembly through the mounting ear 12.

[0077] Please refer to the following: Figure 7 The mounting bracket 1 may also include a first limiting block 13 disposed on the main body 11. The second drive assembly 42 includes a second drive member 421 connected to the main body 11 and a second limiting block 422 disposed on the second drive member 421. The second drive member 421 is fixedly connected to the outer shell 2. The second drive member 421 is used to drive the second limiting block 422 and the outer shell 2 to rotate relative to the mounting bracket 1. The first limiting block 13 is disposed on the movement path of the second limiting block 422 to limit the rotation of the second limiting block 422.

[0078] The first limiting block 13 can be directly connected to the main body 11, or it can be fixed to the main body 11 through other connecting parts. In one embodiment, the mounting bracket 1 further includes a drive base 14, which is connected to the main body 11, and the first limiting block 13 is disposed on the drive base 14.

[0079] The second driving component 421 includes a rotor 423, a stator 424, and a connecting shaft 425. The rotor 423 of the second driving component 421 is connected to the housing 2, and the stator 424 of the second driving component 421 is connected to the mounting bracket 1 via the connecting shaft 425. The second limiting block 422 is connected to the rotor 423. Optionally, the stator 424 of the second driving component 421 is bolted to the drive base 14 via the connecting shaft 425. The rotor 423 of the second driving component 421 rotates relative to the stator 424 of the second driving component 421, causing the housing 2 and the second limiting block 422 to rotate relative to the mounting bracket 1. The first limiting block 13 is disposed on the moving path of the second limiting block 422, so that the first limiting block 13 can restrict the rotation of the second limiting block 422. For example, the second driving member 421 rotates horizontally, and the second driving member 421 and the main body 11 are arranged vertically. The maximum height of the first limiting block 13 to the plane where the main body 11 is located is greater than the minimum height of the second limiting block 422 to the plane where the main body 11 is located. During the rotation of the outer shell 2 driven by the second driving member 421, the first limiting block 13 and the second limiting block 422 may collide, thereby limiting the rotation angle range of the outer shell 2. By setting the first limiting block 13 and the second limiting block 422 of different sizes, the rotatable angle of the outer shell 2 can be adjusted, so that the outer shell 2 can only rotate relative to the mounting bracket 1 within the rotatable angle.

[0080] Please see Figure 6 In one embodiment, the drive module further includes a third drive component 43, which is connected to the housing 2. The vehicle interaction device 100 also includes a rotating bracket 8 and a camera 7 disposed in the housing 2. The camera 7 is mounted on the rotating bracket 8, and the third drive component 43 is connected to the rotating bracket 8.

[0081] The third drive assembly 43 can drive the rotating bracket 8 to rotate, thereby changing the relative positional relationship between the camera 7 and the housing 2. The rotating bracket 8 includes a mounting base 81 connected to the first drive assembly 41, a mounting platform 82 disposed on the mounting base 81, and a connecting rib 83 connecting the mounting base 81 and the mounting platform 82. The mounting base 81 is hollow, and the camera 7 is disposed on the mounting platform 82. The hollow mounting base 81 reduces the overall weight of the vehicle interaction device and provides space to accommodate structures such as the control module, which may include circuit boards and chips for controlling the vehicle interaction device. In one embodiment, one side of the mounting platform 82 is arc-shaped to fit the housing 2, thereby increasing the distribution density of components within the housing 2. The connecting rib 83 may include two intersecting ribs to improve the support stability of the connecting rib 83.

[0082] The third drive assembly 43 includes a third drive member and a third drive shaft. The third drive member is connected to the housing 2 and can also be snapped between the front housing 21 and the rear housing 22. One end of the third drive shaft is connected to the third drive member, and the other end is connected to the rotating bracket 8. The other end of the rotating bracket 8 is rotatably connected to the housing 2. Rotation of the third drive shaft allows the camera 7 mounted on the mounting base 81 to rotate along the axial direction of the third drive shaft. The third drive assembly 43 may also include a bearing sleeved on the outside of the third drive shaft. One end of the third drive shaft is connected to the rotating bracket 8 via the bearing to reduce friction generated by rotation.

[0083] Optionally, the rotatable angle of the housing 2 is from 0° to 300°. In one embodiment, when the rotation angle of the housing 2 is 0°, the camera 7 faces the driver's seat; when the rotation angle of the housing 2 changes from 0° to 300°, the field of view of the camera 7 can sequentially cover the rear seats of the driver's cab, the front passenger seat, and the area in front of the vehicle.

[0084] Please refer to the following: Figure 8 In some embodiments, the in-vehicle interactive device 100 also includes a slide rail 9, and the mounting bracket 1 is movably connected to the slide rail 9.

[0085] In a vehicle, the in-vehicle interactive device 100 is installed in the vehicle. The slide rail 9 can be positioned along the width of the vehicle, allowing the display module 3 to move along this width to face different passengers. The slide rail 9 can protrude from the dashboard assembly or be embedded in it. By providing the slide rail 9, it is convenient to move the housing 2 and functional modules such as the display module 3 housed within the housing 2. The mounting bracket 1 may also include a slider, with the main body 11 connected to the slider via a mounting ear 12. The slider and the slide rail 9 are movably connected.

[0086] Please see Figure 9 This application also provides a vehicle, including:

[0087] Frame;

[0088] Both the instrument panel assembly and the light-transmitting wind deflector 201 are mounted on the vehicle frame;

[0089] As provided in the first aspect, the in-vehicle interactive device 100 is mounted on the instrument panel assembly;

[0090] When the in-vehicle interactive device 100 is in the first display mode, at least part of the display module 3 displays an image at the opening 5. When the in-vehicle interactive device 100 is in the second display mode, at least part of the display module 3 projects a projection beam L onto the light-transmitting windshield through the opening 5.

[0091] The light-transmitting windshield 201 can be the windshield located at the front of the vehicle. The light emitted from the display module 3 can fall onto the holographic film of the light-transmitting windshield 201 to achieve a head-up display.

[0092] The vehicle provided in this application can achieve the beneficial effects that the in-vehicle interactive device 100 provided in any embodiment of the first aspect can achieve, and will not be described in detail here.

[0093] The second aspect of this application also provides a control method for the in-vehicle interactive device of the first aspect embodiment described above, the method comprising the following steps:

[0094] S101, when the in-vehicle interactive device is in the first display mode, control at least a portion of the display module to display an image at the opening;

[0095] S102, when the in-vehicle interactive device is in the second display mode, control at least part of the display module to project a projection beam through the opening to the outside of the housing so as to project an image onto the vehicle's light-transmitting windshield.

[0096] The control method for the in-vehicle interactive device can also be applied to vehicles equipped with such devices, which can be the aforementioned vehicles, with the in-vehicle interactive device mounted on the dashboard assembly. The in-vehicle interactive device can switch between multimedia display mode and head-up display mode based on received control commands. Control commands can be voice control information issued by the driver or passengers, control commands issued to the in-vehicle interactive device via mobile terminals such as smartphones, or posture information such as body posture, gestures, or facial expressions collected from the driver or passengers.

[0097] Please see Figure 10 The in-vehicle interactive device can acquire voice control information through a microphone array sensor and parse it to obtain control commands. The process of parsing voice control information includes: first, front-end signal processing; if multiple voice control messages are received, the voice information of a specific person (e.g., the driver) is separated using a target speaker extraction method; then, a speech recognition algorithm model performs feature extraction and pattern matching on the voice control information, followed by semantic understanding using a natural language understanding algorithm model to obtain the control commands corresponding to the voice control information. The in-vehicle interactive device can also acquire image information through a camera and parse it to obtain posture information. For image data, an image processing algorithm model can extract human joint coordinates, gesture features, and facial features, matching these features with a pre-set template library to obtain posture information corresponding to the image data. The in-vehicle interactive device pre-stores structured operation templates corresponding to all control commands; when a control command is received, the corresponding interactive operation is automatically executed.

[0098] When passengers control the in-vehicle interactive device via voice, the processing module can calculate the sound source location using a microphone array-based sound source localization algorithm. This allows the first and / or second drive components to move, enabling the display module to face the sound source location through an opening. Specifically, the display module can face the passenger issuing the voice command. The microphone array-based sound source localization algorithm is based on Time Difference of Arrival (TDOA). It first calculates the time difference based on the phase-differential sound source signals collected by each microphone sensor in the array. Typically, a Generalized Cross Correlation (GCC) function is used, with weighting applied in the cross-power spectral domain. Then, an Inverse Fast Fourier Transform (IFFT) operation is performed to find the peak time delay. Next, a sound source localization model is established using the geometry of the microphone array, and the model is solved to estimate the sound source location. For example, when the sound source is located in the driver's seat, the in-vehicle interactive device moves horizontally to the center of the instrument panel assembly and rotates the housing so that the display module faces the driver through the opening; when the sound source is located in the passenger seat, the housing is rotated so that the display module faces the passenger through the opening.

[0099] In one embodiment, when the sound source is located at the driver's seat, the in-vehicle interactive device moves horizontally along the slide rail to the center of the center console and rotates to -60 degrees relative to the mounting bracket, so that the opening of the in-vehicle interactive device faces the driver; when the sound source is located at the passenger seat, the in-vehicle interactive device moves horizontally along the slide rail in front of the passenger seat and rotates to 0 degrees relative to the mounting bracket, so that the opening of the in-vehicle interactive device faces the passenger. When a command to switch to the second display mode is received, the in-vehicle interactive device moves horizontally along the slide rail to a position directly in front of the driver and rotates to 180 degrees relative to the mounting bracket, facing the windshield; when a command to switch to the first display mode is received, the in-vehicle interactive device moves horizontally along the slide rail to a position directly in front of the passenger seat and rotates to 180 degrees relative to the mounting bracket, facing the windshield.

[0100] Of course, drivers and passengers can also directly control the in-vehicle interactive device to rotate to the desired angle via voice commands or mobile devices. For example, by setting the specific position and angle of the in-vehicle interactive device through a mobile app, the device will move to the user-defined position and rotate to the specified angle.

[0101] The control method for the in-vehicle interactive device provided in this application can achieve the beneficial effects that the in-vehicle interactive device provided in any embodiment of the first aspect can achieve, and will not be described in detail here.

[0106] The first driving component is controlled to drive the projection component to be positioned opposite the second opening, and the projection component is controlled to project a projection beam onto the light-transmitting windbreak component through the second opening.

[0107] In the case of multiple openings, the projection component can be moved by the first driving component to drive the beam of the projection component to different openings, so as to realize projection display and transmission display.

[0108] In another embodiment, the display module includes a projection component, a rotating bracket, and a display screen body. The projection component is mounted on the rotating bracket, the first driving component is connected to the rotating bracket, and the display screen body is movably connected to the outer casing.

[0111] S102 includes:

[0112] The display screen moves relative to the outer casing, and the first drive component drives the projection component to project a projection beam through the opening onto the light-transmitting windbreak.

[0113] In the case of a display screen and a projection component, the housing can be moved by a second drive component so that the opening corresponds to the projection component or the display screen, so that the projection component or the display screen can display through the opening.

[0114] Please see Figure 11 In one embodiment, such as S310-S390, when the in-vehicle interactive device is in projection mode, the opening of the in-vehicle interactive device faces the light-transmitting windshield, exposing the projection component. The projection component projects a projection beam onto the light-transmitting windshield through the opening. The in-vehicle interactive device can collect audio data through a microphone array and obtain key information from the audio data. Based on the key information, it can provide interactive feedback, including but not limited to voice feedback, projection beam feedback, and control of the vehicle's functional modules.

[0115] Please see Figure 12 In one embodiment, such as S210-S280, when the in-vehicle interactive device is in interactive mode, the opening of the in-vehicle interactive device faces the driver and passengers, and the display screen covers the opening. The in-vehicle interactive device can collect audio data through a microphone array and video data through a camera, and obtain key information from the audio and video data. Based on the key information, it provides interactive feedback, which includes, but is not limited to, voice feedback, projection beam feedback, and control of the vehicle's functional modules.
