[0002] With the development of automotive intelligence, zero-gravity seats have gradually become a core feature of high-end models. Additionally, panoramic sunroofs have become standard equipment in most new energy vehicles in recent years. However, most cabin information in these technologies is concentrated on the driver and passenger screens and the central control screen. When using zero-gravity seats in a reclining position, occupants cannot directly view the main information interfaces. Furthermore, the vehicle's seat system, body control system, panoramic sunroof, and infotainment system typically have independent control units, communication protocols, and development cycles. This results in high barriers to interaction between systems, making it difficult to achieve deep and real-time cross-domain collaboration. Consequently, efficient information acquisition and an immersive experience cannot be achieved while the user is comfortably reclining, leading to a poor user experience. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The vehicle control method, vehicle control system, electronic equipment, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0029] The vehicle control method can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0030] The vehicle control method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the vehicle control method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The vehicle control method provided in this application embodiment will be described below using an electronic device as the execution subject.

[0031] like Figure 1 As shown, the vehicle control method includes steps 110 and 120.

[0032] Step 110: Obtain the positional information of the vehicle seats and the body data of the person sitting in the vehicle seats; In this step, the vehicle seat can be a zero-gravity seat, such as... Figure 2 As shown in Figure 1, the zero-gravity seat can automatically adjust the occupant's sitting posture to a reclining angle that is close to "even weight distribution", thereby reducing local pressure on the occupant's spine and ischial tuberosities, improving blood circulation and enhancing comfort during long-term sitting.

[0033] like Figure 3 As shown, in actual execution, in response to the mode switching command, the seat can drive the backrest, seat cushion and leg rest to move synchronously through the motor, and achieve precise switching of seat posture by combining multi-point pressure and angle sensors, seat control unit and corresponding control algorithm.

[0034] For example, users can input commands via physical buttons, the central control screen, or a voice recognition module. For instance, one or more clearly marked physical buttons can be placed on the door trim panels, center console, or seat body, allowing users to input mode switching commands by pressing them. Alternatively, a graphical virtual button or switch can be provided within the vehicle's central control screen, allowing users to input mode switching commands by touching the virtual button or switch. Or, the command input can be integrated into a touch panel on the seat armrest (such as...). Figure 2 As shown in Figure 3, a multi-point gesture-enabled touch panel can be installed on the seat armrest. The touch panel will automatically light up when the user's hand approaches, or it can be woken up when the user lightly touches or presses a dedicated physical button on the armrest. After the panel is woken up, the user can trigger mode switching by tapping, or mode switching commands can be generated in other ways. This application does not limit this.

[0035] For example, upon receiving a user's mode switching command, the seat control unit can call the preset zero-gravity seat back tilt angle and drive multiple motors to make the backrest, seat cushion and leg rest move synchronously. The pressure sensor array can provide real-time feedback on body pressure distribution, the tilt sensor can provide feedback on component angles, and the control algorithm can dynamically correct the motor output until the target posture is achieved and the pressure distribution is uniform. After the switching is completed, a zero-gravity mode activation completion signal can be output.

[0036] It provides users with a convenient one-click zero-gravity seat mode switching operation, and the closed-loop control can ensure a smooth, safe and accurate adjustment process.

[0037] Vehicle seat pose information is used to characterize the seat's position and orientation within the vehicle space. This pose information can include the seat's X, Y, and Z coordinates in the vehicle coordinate system, as well as the seat back tilt angle, etc. Figure 2 As shown in Figure 6, the tilt angle of the seat back can be collected. The backrest tilt angle is the angle between the seat back and the vertical direction.

[0038] In actual implementation, the tilt angle of the seat back can be sampled in real time by an angle sensor that integrates a gyroscope and an accelerometer, or a Hall sensor or rotary encoder can be integrated inside the motor that controls the tilt of the seat back to sample the tilt angle of the seat back in real time, or other methods can be used to obtain the tilt angle of the seat back. This application does not limit this.

[0039] Among these features, when the vehicle is in motion, the range of seat backrest tilt angles can be limited; for example, it can be set... The backrest tilt angle can be 20°, 30° or 40°, etc., and this application does not limit it.

[0040] When the vehicle is not in motion, the seat back tilt angle can be set to a range of [range missing]. For example, the backrest tilt angle can be 0°, 20°, 45°, 60° or 90°, etc., which are not limited in this application.

[0041] The body data of the passenger can be used to characterize the passenger's body shape and posture. The body data can include height information and sitting height information. Images of the passenger can be captured by in-vehicle cameras, and the key points of the human body can be identified from the images to obtain parameters such as the passenger's height based on the proportional relationship between the key points.

[0042] Alternatively, the body data of the passenger can be pre-recorded to create a personalized profile. For example, the user's height information can be entered, and the user's physiological characteristics (such as facial information or fingerprint information) can be associated with the height information and stored together. Before or during the ride, the passenger can select the height information corresponding to the current passenger from the personalized profile, or the current passenger's physiological characteristics can be identified to obtain the height information corresponding to the current passenger; or the passenger's body data can be obtained through other means, which are not limited in this application.

[0043] Step 120: Based on the pose information and body data, control the vehicle's display device to display the first display area at the corresponding position; In this step, the vehicle's display device is installed on the inner wall of the vehicle's roof, such as... Figure 2As shown in Figure 2, a panoramic sunroof can be used to provide viewing functionality for the vehicle's seating area. This can be achieved using a technology similar to transparent television, where the sunroof remains transparent when no content is displayed, and activates corresponding self-emissive pixel units to display content. The panoramic sunroof is a large, light-transmitting structure covering most of the vehicle's roof, made of high-strength glass or composite materials, replacing the traditional segmented sunroof. Panoramic sunroofs can create a sense of spaciousness inside the vehicle and can be combined with variable-light panoramic sunroof technology to provide a similar shading experience to traditional sunshades.

[0044] like Figure 3 As shown, in actual implementation, a domain controller (such as...) can be set up in the vehicle or seat. Figure 2 As shown in Figure 4), the domain controller can obtain the zero-gravity mode activation completion signal of the seat control unit through the CAN bus, and then send a start command to the display device (the start command includes initial display mode parameters, etc.). The driving circuit in the display device can switch the working state of self-emissive pixels (such as OLED or Micro LED, etc.) and load preset interfaces (such as vehicle status, environmental information, and vehicle home page, etc.) to the default display area. OLED stands for Organic Light Emitting Diode, which refers to light-emitting diode display technology made of organic semiconductor materials, and has the characteristics of self-emissiveness, wide viewing angle, high contrast and low power consumption. Micro LED stands for Micro Light Emitting Diode, which specifically refers to a new type of self-emissive display technology with a pixel size of less than 100 micrometers. It is achieved by miniaturizing the traditional LED array and realizing matrix active driving. This technology has the advantages of high brightness, long life and low power consumption. CAN stands for Controller Area Network Bus, which is a serial communication protocol used in industrial control and automotive electronics. It adopts differential signal transmission and has the characteristics of strong real-time performance, outstanding anti-electromagnetic interference capability and long transmission distance.

[0045] By acquiring the zero-gravity mode activation completion signal of the seat in real time, and responding to the zero-gravity mode activation completion signal to start the display function of the display device, the display device can be started without any additional operation by the user, which improves the smoothness and convenience of the user experience and avoids the inconvenience of the user having to look for the display device control switch after lying down.

[0046] Based on pose information and body data, it can be determined in which area the display device should display content in the current state, thus defining the "corresponding position." The display device can then be controlled to display a first display area at that position. This first display area is used to display the target content, such as... Figure 2 Example 5 illustrates the panoramic sunroof display area. When using the panoramic sunroof (i.e., the display device), the display area can be adjusted according to the tilt angle of the seat back to ensure that the user can naturally view the displayed content while lying down.

[0047] The target content may include vehicle status and environmental control information, navigation and trip information, communication and social information, entertainment and multimedia information, as well as external environment and augmented reality information.

[0048] In actual execution, for example, when the backrest tilt angle is detected to change from 40° to 80°, and the head position of the passenger is detected to move backward and the passenger's line of sight is directed towards the front of the roof, the perspective projection can be recalculated based on the new backrest tilt angle and head position to obtain a new first display area, and the display device can be controlled to display the target content in the new first display area.

[0049] In some embodiments, when there are multiple passengers, controlling the vehicle's display device to display a first display area at a corresponding location may include: The display device controlling the vehicle displays multiple primary display areas.

[0050] In this embodiment, multiple first display areas are used to display different target content to multiple passengers.

[0051] The single-seat linkage mechanism can be extended into a multi-seat collaborative system for the entire vehicle. For example, a central cockpit controller can be set up to coordinate all seats and display devices. Each seat is an intelligent node, including a seat control unit and a sensing system. The display device is divided into multiple independently controllable display zones (e.g., driver's area, passenger's area, rear left area, and rear right area). That is, the display screen of the display device can be adaptively divided into multiple first display areas according to the viewing needs of passengers in different areas of the passenger cabin. Each first display area can provide viewing needs for passengers in the corresponding position. Independent panoramic sunroof partition display can be achieved for the front and rear areas, and content can be shared across seats.

[0052] During the research and development process, the inventors discovered that in related technologies, when the user's posture changes from the traditional "sitting upright" to "lying down", the entire cockpit's interaction logic (such as information display location, touch area, and gesture interaction) needs to be redefined, making the control logic quite cumbersome.

[0053] In this application, by constructing a closed-loop linkage system for zero-gravity seat posture perception and panoramic canopy intelligent display, the canopy can be dynamically adjusted to adjust the display area and content layout based on the real-time collected seat back tilt angle. This allows the screen display distribution to dynamically match the user's viewing angle, ensuring that the user can view the content on the display device even when lying down. This solves the problem of difficulty in obtaining information when the user is in a comfortable lying position, thus improving the user experience. Furthermore, based on real-time collected data such as the seat back tilt angle, the display area on the display device can be adaptively adjusted to suit the user's viewing angle in different postures. The same set of interaction logic can be used regardless of the user's posture, making operation convenient.

[0054] According to the vehicle control method provided in this application embodiment, by acquiring the posture information of the vehicle seat and the body data of the passenger, the display device is controlled to display the first display area at the corresponding position based on the posture information and body data. This realizes the linkage control between the seat and the display device, so that the passenger can obtain the content information displayed by the display device even in a comfortable resting posture (such as a lying posture). This solves the problem that the lying posture information is not visible due to the independent functions of the seat and the display device, and improves the user experience.

[0055] In some embodiments, step 120 may further include: Based on pose information and body data, the position information of the center point of the first display area on the display device is obtained; Based on the location information corresponding to the center point, the control display device displays the first display area at the corresponding position.

[0056] In this embodiment, body data may include user viewpoint pose, etc., to characterize the user's gaze direction.

[0057] The center point of the first display area can be obtained based on the user's body data and pose information. Then, the center point of the first display area can be converted into pixel coordinates on the display device. For example, the correspondence between the 2D pixel coordinates of the display device and its 3D spatial coordinate system can be established in advance, and the conversion can be performed according to the correspondence to obtain accurate pixel coordinates. These pixel coordinates represent the center position of the first display area on the screen.

[0058] The display device can be controlled to display the first display area at the corresponding position, using the location information corresponding to the center point as the center.

[0059] For example, when it is detected that the user has adjusted the seat back and the head position has moved accordingly, the position information of the center point of the first display area on the display device can be recalculated based on the new line of sight and the tilt angle of the seat back. If the new position information is found to be closer to the rear of the vehicle than the previous position, the new center point pixel coordinates can be obtained through coordinate transformation. The display device can then move the display center of the first display area from the old position to the new position, and perform real-time perspective correction on the image.

[0060] In some embodiments, obtaining the position information of the center point of the first display area on the display device based on pose information and body data may include: Based on pose information and body data, the coordinates of the intersection point between the line of sight of the person sitting and the display device are obtained; The coordinates of the intersection point are used to determine the position information of the center point on the display device.

[0061] In this embodiment, based on a preset standard sitting posture and the body data of the passenger (such as height information), key dimensions such as the passenger's thigh length, torso length, and eye point can be calculated. Then, combined with the vehicle seat's posture information (such as the backrest tilt angle), the 3D position of the center point of the passenger's eyes (i.e., "eye point") in the vehicle coordinate system can be calculated.

[0062] In a relaxed state, a person's gaze is usually at a fixed angle to the direction of their torso (i.e., the back of a vehicle seat), or by default, they are looking straight ahead. This angle can be predefined, such as... Figure 2 As shown, the line of sight can be defined as perpendicular to the direction of the vehicle seat back; that is, the angle between the line of sight and the vertical direction is... Then, starting from the eye point, a ray is emitted along the predicted line of sight in the relaxed state. The intersection of the ray with the plane equation where the roof display device is located is calculated, and the intersection point is determined as the predicted line of sight landing point, that is, the position information of the center point of the first display area on the display device.

[0063] In actual implementation, such as Figure 3 As shown, the domain controller can call pre-stored ergonomic models. (e.g., a height-viewpoint mapping table), where the ergonomic model is a database or function pre-established through extensive experiments and data, describing the height of a person... For passengers whose seat back is reclined at an angle of [missing information] At that time, where will the occupant's relaxed gaze naturally point, for example, in In a standard sitting position, one's natural line of sight might be directed towards the front of the roof; In a semi-reclining position, one's gaze is naturally more vertically upward, pointing towards the center of the roof.

[0064] By inputting posture information and body data into the ergonomic model, the coordinates of the intersection point between the passenger's line of sight and the display device can be obtained: ,in, For body data, For pose information, The coordinates of the intersection point are used to determine the position information of the center point on the display device.

[0065] The window can be moved to the area centered on the intersection coordinates, and the first display area will be displayed at the corresponding position.

[0066] In some embodiments, controlling the display device to display a first display area at the corresponding position based on the position information corresponding to the center point may include: Based on the boundary parameters of the display device, determine the size information of the first display area; Using the position information corresponding to the center point as the center, and based on the size information, control the display device to display the first display area at the corresponding position.

[0067] In this embodiment, the boundary parameters of the display device may include the maximum width of the display device. and maximum height .

[0068] You can define a default or user-selected display area size, i.e., the initial width W and height H, and you can inspect the display area centered on the intersection point coordinates. Does it exceed the boundaries of the display device?

[0069] If the display area exceeds the boundaries of the display device, the size of the display area can be reduced proportionally until the display area can be completely contained within the display screen of the display device, thus obtaining the final size information of the first display area. and .

[0070] Center point pixel coordinates Based on this, determine the coordinates of the top left corner of the final first display area. The controller can refresh the pixel lighting positions according to the new coordinate matrix to display a size of [value] at the specified position on the display device. The first display area.

[0071] According to the vehicle control method provided in the embodiments of this application, the position information of the center point of the first display area on the display device is obtained by using the tilt angle of the vehicle seat back and the body data of the passenger, so as to control the display device to display the first display area at the corresponding position. This allows the display area to adapt to the lying posture of the passenger, so that the passenger can comfortably and naturally view the content on the display device without adjusting their posture, thereby improving the efficiency of information acquisition and immersion, and enhancing the user experience.

[0072] In some embodiments, the method may further include: The brightness and transmittance of the second display area in the control display device are at least one lower than the brightness and transmittance of the first display area, respectively.

[0073] In this embodiment, the first display area is the information focus area, the second display area is the display area on the display screen of the display device other than the first display area, and the second display area is the environmental background area.

[0074] Display devices can have local dimming and pixel-level dimming functions. For example, display devices can use Micro-LED technology or transparent OLED technology to achieve pixel-level dimming.

[0075] In some embodiments, the display device may also be electrochromic glass and a projection display system, which can utilize glass partition coloring as a dynamic display background, and this application does not limit it.

[0076] The brightness of the second display area can be reduced, or the transmittance of the second display area can be reduced, or both the brightness and transmittance of the second display area can be reduced, so that at least one of the brightness and transmittance of the first display area is lower than at least one of the brightness and transmittance of the first display area, respectively. This application does not limit this.

[0077] For example, brightness and transmittance commands can be sent to different areas based on the position and shape of the first display area. Inside the first display area, the brightness command can be "high" or "full brightness," for example, the brightness of the first display area can be set to 100%. The transmittance command can be "low" or "opaque," for example, the transmittance of the first display area can be set to 0%. Outside the first display area (i.e., the second display area), the brightness command can be "low" or "off," for example, the brightness of the second display area can be set to 10%. The transmittance command can be "high" or "transparent," for example, the transmittance of the second display area can be set to 98%.

[0078] In this application, by significantly reducing at least one of the brightness and transmittance of the second display area, such that at least one of the brightness and transmittance of the second display area is lower than at least one of the brightness and transmittance of the first display area, the user's viewing immersion is enhanced, the environmental transparency is improved, and the user's experience is enhanced.

[0079] like Figure 3 As shown, in some embodiments, the method may further include: Obtain the current environmental parameters of the vehicle's environment; Adjust the first display area based on the current environmental parameters.

[0080] In this embodiment, the current environmental parameters may include ambient light intensity, weather conditions, and external visibility, wherein the ambient light intensity is the light intensity around the top of the vehicle (e.g., Figure 2 (As shown in Figure 7).

[0081] A photosensitive sensor (such as) can be used Figure 2 As shown in Figure 8, the ambient light intensity is collected in real time, and the data can be converted by an ADC (analog-to-digital converter, an electronic device used to convert continuous analog signals into discrete digital signals) and then input into the domain controller.

[0082] Alternatively, the ambient light sensor can be replaced with a panoramic canopy integrated transparent photosensitive module (embedded in the glass interlayer) to achieve integrated acquisition of light data and display area. Other methods can also be used to acquire ambient light intensity, which is not limited in this application.

[0083] After obtaining the environmental parameters, the various attributes of the first display area can be automatically adjusted according to the preset strategy.

[0084] Based on the current environmental parameters, the brightness, contrast, color temperature, hue, internal layout, and transparency of the first display area can be adjusted.

[0085] For example, when a vehicle enters a tunnel from a sunny outdoor highway and a sudden drop in light intensity is detected, in response to the signal of darkening of the environment, the brightness of the first display area can be smoothly reduced from high to night mode based on the current light intensity, and the color temperature of the displayed content can be adjusted from cool white to warm yellow.

[0086] In some embodiments, adjusting the first display area based on current environmental parameters may include: Based on the current environmental parameters, determine the screen display parameters corresponding to the first display area; Adjust the first display area based on the screen display parameters.

[0087] In this embodiment, the display parameters may include brightness, contrast, color temperature, transparency, etc.

[0088] After collecting the current environmental parameters, the screen display parameters can be calculated or obtained by looking up the table based on the current environmental parameters, and then the first display area can be adjusted according to the screen display parameters.

[0089] In some embodiments, determining the screen display parameters corresponding to the first display area based on current environmental parameters may include: Based on the preset correspondence between environmental parameter ranges and screen display parameters, the screen display parameters corresponding to the environmental parameter range of the current environmental parameters are determined as the screen display parameters corresponding to the first display area.

[0090] In this embodiment, the correspondence between the environmental parameter range and the screen display parameters can be a preset functional relationship or a mapping table, which is not limited in this application.

[0091] The collected raw environmental parameters can be classified and ranged, such as those related to ambient light intensity. Under these circumstances, it can be determined that the current environment is low light; in terms of light intensity Under these circumstances, it can be determined that the current environment is normal; under the light intensity In this case, it can be determined that the current environment is one of strong light.

[0092] For example, if the current environment is detected to be a strong light environment, the corresponding combination of display parameters can be retrieved from the mapping table, such as setting the brightness to the maximum value, the contrast to high, the color temperature to cool, and the transparency to high. The domain controller can send the determined parameter combination to the display driver controller, which can then call the corresponding hardware driver instructions to change the physical properties of the first display area.

[0093] In some embodiments, determining the screen display parameters corresponding to the first display area based on current environmental parameters may include: Based on the preset correspondence between environmental parameter ranges and brightness information, the brightness information corresponding to the environmental parameter range in which the current environmental parameter is located is determined as the brightness information corresponding to the first display area. Based on the current environmental parameters and the brightness information corresponding to the first display area, the contrast information corresponding to the first display area is determined.

[0094] In this embodiment, a preset brightness mapping table can be used to obtain brightness information corresponding to the current environmental parameters, so as to ensure that the average brightness of the first display area matches the ambient light intensity.

[0095] A contrast decision function that takes brightness into account can be used to determine the contrast information corresponding to the current environmental parameters based on the current environmental parameters and brightness information.

[0096] For example, in a bright light environment (with high light intensity and high brightness information), a higher gamma value or a more aggressive tone mapping curve can be used to achieve high contrast; in a low light environment (with low light intensity and low brightness information), a standard or lower gamma value can be used to achieve moderate or low contrast; in a normal environment, standard contrast can be used.

[0097] Contrast information can be gamma value or contrast intensity value, etc., and this application does not limit it.

[0098] Given the brightness information L and contrast information C, the display driver can adjust the average brightness of the entire first display area to the target value L by controlling the anode current of the pixels (as in Micro-LED / OLED) or the backlight brightness (as in LCD). The graphics processor can load the contrast information C (such as a specific gamma value) into a gamma lookup table. Before the image data in the first display area is output to the screen, it will be remapped through the gamma curve, thereby increasing or decreasing the contrast.

[0099] It should be noted that brightness and contrast adjustments can be applied simultaneously, ultimately presenting a bright (or soft) image with distinct layers and clear details on the first display area.

[0100] In actual execution, piecewise functions can be pre-constructed to determine the brightness information corresponding to the current light intensity.

[0101] For example, in low-light environments, a linear function can be used to adjust the brightness information; in normal environments, a logarithmic function can be used to adjust the brightness information; and in bright light environments, the brightness can be adjusted to a fixed value (such as the maximum value).

[0102] For example, the domain controller can calculate the screen display brightness L in segments based on the ambient light intensity E:

[0103] in, It is a constant and satisfies , , and These represent the intensity thresholds that distinguish between low and high light levels, respectively. To enable the display device to support the highest brightness of the displayed image.

[0104] Brightness can be adjusted by regulating the anode current of the display pixel driver IC (an integrated circuit, a miniature electronic device that integrates a large number of transistors, resistors, and capacitors onto a single chip using semiconductor technology). For example, for Micro-LED / OLED (pixels emit their own light), the driving current of each pixel can be directly controlled; the higher the current, the higher the pixel brightness. For LCDs (which require backlighting), the "anode current" can be understood as the control of the backlight module. Whether it's global dimming or local dimming, the overall or regional brightness can be adjusted by controlling the current of the LED backlight.

[0105] Contrast adjustment can be achieved through independent gamma correction of RGB subpixels. Gamma correction is a technique used to compensate for the nonlinear light response characteristics of display devices, and can be used to correct the nonlinear relationship between the input signal and the output brightness. The system can adjust the contrast by dynamically loading different gamma value curves. For example, in a strong light environment (such as midday sunlight), a curve with a higher gamma value can be used to stretch the midtones, making the dark areas darker and the bright areas brighter, thereby enhancing the overall contrast and ensuring that the image is visible without appearing washed out. In a low light environment (such as at night or in a tunnel), a curve with a lower gamma value can be used to compress the midtones, brighten the details in the dark areas, and prevent the highlights from being too glaring, thereby creating a softer viewing experience.

[0106] It can perform gamma correction on R, G, and B sub-pixels independently, and optimize the grayscale performance of the three primary colors separately. It can not only adjust the contrast between light and dark, but also correct color cast, ensuring accurate color reproduction under different brightness levels.

[0107] In this application, the brightness and contrast are automatically increased under strong light (such as midday sunlight) to ensure that the image is visible without appearing washed out; under weak light (such as at night or in a tunnel) the brightness is automatically reduced to avoid glare, while maintaining sufficient contrast to see details clearly. This can optimize visual clarity and comfort, and improve the display usability in all weather conditions and all scenarios.

[0108] According to the vehicle control method provided in the embodiments of this application, by integrating an ambient light sensor and an intelligent dimming algorithm, the display parameters of the optimal display area are calculated in real time based on the real-time ambient light parameters and the seat back tilt angle. This achieves multiple adaptive adjustments to the display area positioning, brightness, and contrast. The adjustment mechanism and seat posture are linked to form a multi-dimensional perception closed loop, forming a cockpit interaction solution that combines immersive experience, human-centered design, and energy-saving advantages, thereby improving the user experience.

[0109] like Figure 3 As shown, in some embodiments, the vehicle includes a control device, which is used for: Receive adjustment instructions; Adjust the target content in the first display area based on the adjustment command.

[0110] In this embodiment, the control device may include a voice control device, an in-vehicle terminal control device, and a central control screen control device, etc.

[0111] The voice control device may include an in-vehicle microphone array and an integrated voice recognition module; the in-vehicle terminal control device may include physical control terminals (such as multi-function buttons on the steering wheel, rear armrest screens, and physical buttons / knobs on the door panels), as well as mobile terminals (such as the user's mobile phone, which connects to the vehicle's infotainment system via Bluetooth or a network); the central control screen control device may be the main touch screen display in the center of the vehicle's dashboard.

[0112] The control device can be connected to the display driver controller of the display device or the main controller of the entertainment system to adjust the display content in the first display area based on adjustment commands.

[0113] Among them, the content of the first display area can be adjusted in many ways based on the adjustment commands. For example, media control (such as play / pause, volume increase / decrease, previous / next track and playback progress dragging, etc.), display settings (brightness, contrast, color temperature and saturation adjustment, etc.) and content layout (such as screen scaling and window position fine adjustment, etc.) can be performed.

[0114] In some embodiments, the control device may be located on the armrest of the vehicle seat.

[0115] In this embodiment, the control device may be a capacitive touch panel on the seat armrest, or a non-contact millimeter-wave gesture radar (supporting user hover gesture operation), or a physical button / knob set on the seat armrest, or a voice microphone, etc., which are not limited in this application.

[0116] Among them, the capacitive touch sensor array can be integrated into the handrail surface to detect the coordinates of the user's finger. The capacitive touch panel supports multi-touch operations, such as zooming, swiping, and clicking.

[0117] For example, when using a display device to play entertainment information, users can directly slide on the touchscreen of the armrest to adjust the volume; they can use two fingers to pinch to zoom in and out; or they can make a swipe gesture in the air to switch to the next song or movie.

[0118] By installing control devices on the armrests of the vehicle seats, users can adjust the target content in the first display area based on the control devices. The operation panel can be reached by the user's arm hanging naturally, without having to lift their hand to operate the central control screen or find other buttons.

[0119] According to the vehicle control method provided in the embodiments of this application, by setting a control device on the armrest of the vehicle seat, the user can adjust the target content in the first display area based on the control device. The user can reach the operation panel with his arm hanging down naturally, without having to lift his hand to operate the central control screen or find other buttons. This achieves natural and efficient interaction in zero-gravity posture, improves the convenience and comfort of operation in the reclining state, enhances the cabin interaction experience, and achieves a unity of comfort and interaction efficiency.

[0120] In some embodiments, step 110 may include: Upon receiving an adjustment command for the vehicle seat, the system acquires the vehicle seat's position and posture information, as well as the body data of the person sitting in the vehicle seat.

[0121] In this embodiment, the adjustment commands may include direct user commands, such as the user pressing physical buttons or screen buttons such as "zero gravity mode", "rest mode" or "memory position 1", or the user issuing commands such as "flatten the seat" via voice; the adjustment commands may also include intelligent scene commands from the system, such as when the vehicle enters "cinema mode", the system automatically triggers the linkage adjustment of the seat and screen.

[0122] Upon receiving an adjustment command for the vehicle seat, it indicates that the seat back tilt angle may have changed, and the system can automatically obtain the latest vehicle seat posture information and the body data of the passenger.

[0123] Upon receiving the adjustment command, the system automatically triggers actions to acquire posture information and body data.

[0124] In this application, by receiving the adjustment command corresponding to the vehicle seat, the positional information of the vehicle seat and the body data of the passenger are then acquired. This avoids the continuous high-frequency data acquisition and calculation without any command, thereby reducing system power consumption and computing power burden. It also ensures that the acquired data is the latest state after the command is issued, avoiding errors caused by using outdated data for calculation.

[0125] It should be noted that during zero-gravity mode and when the display device is activated, the tilt sensor and ambient light sensor can work continuously, and the cockpit domain controller can continuously receive data. If a significant change in the seat back tilt angle is detected (such as when the user actively adjusts their posture and the domain controller detects the corresponding adjustment command for the vehicle seat) or a significant change in ambient light intensity (such as when entering a tunnel or when the sun is obscured by clouds), the controller can readjust the first display area based on the latest posture information, body data, and current environmental parameters, thereby ensuring the continuous stability of adjustment and experience.

[0126] The vehicle control method provided in this application can be executed by the vehicle's control system. This application uses the vehicle's control system executing the vehicle control method as an example to illustrate the vehicle control system provided in this application.

[0127] This application also provides a vehicle control system.

[0129] The first processing module 410 is used to acquire the posture information of the vehicle seat and the body data of the person sitting on the vehicle seat. The second processing module 420 is used to control the vehicle's display device to display a first display area at a corresponding position based on pose information and body data; the first display area is used to display target content, and the display device is set on the inner wall of the vehicle's roof.

[0130] According to the vehicle control system provided in this application embodiment, by acquiring the posture information of the vehicle seat and the body data of the passenger, the system controls the display device to display the first display area at the corresponding position based on the posture information and body data. This realizes the linkage control between the seat and the display device, enabling the passenger to obtain the content information displayed by the display device even in a comfortable resting posture (such as a lying posture). This solves the problem of the inability to see the lying posture information caused by the independent functions of the seat and the display device, and improves the user experience.

[0131] In some embodiments, the vehicle control system may be a body control system, such as, the vehicle control system may include, for example, a body control system. Figure 2 The cockpit domain controller shown in Figure 4 is used to realize the linkage control between the vehicle seats and the display device.

[0133] In this embodiment, the control device may include a voice control device, an in-vehicle terminal control device, and a central control screen control device, etc.

[0134] The voice control device may include an in-vehicle microphone array and an integrated voice recognition module; the in-vehicle terminal control device may include physical control terminals (such as multi-function buttons on the steering wheel, rear armrest screens, and physical buttons / knobs on the door panels), as well as mobile terminals (such as the user's mobile phone, which connects to the vehicle's infotainment system via Bluetooth or a network); the central control screen control device may be the main touch screen display in the center of the vehicle's dashboard.

[0135] The control device can be connected to the display driver controller of the display device or the main controller of the entertainment system to adjust the display content in the first display area based on adjustment commands.

[0136] Among them, the content of the first display area can be adjusted in many ways based on the adjustment commands. For example, media control (such as play / pause, volume increase / decrease, previous / next track and playback progress dragging, etc.), display settings (brightness, contrast, color temperature and saturation adjustment, etc.) and content layout (such as screen scaling and window position fine adjustment, etc.) can be performed.

[0137] In some embodiments, the control device may be located on the armrest of the vehicle seat.

[0138] In this embodiment, the control device may be a capacitive touch panel on the seat armrest, or a non-contact millimeter-wave gesture radar (supporting user hover gesture operation), or a physical button / knob set on the seat armrest, or a voice microphone, etc., which are not limited in this application.

[0139] Among them, the capacitive touch sensor array can be integrated into the handrail surface to detect the coordinates of the user's finger. The capacitive touch panel supports multi-touch operations, such as zooming, swiping, and clicking.

[0140] For example, when using a display device to play entertainment information, users can directly slide on the touchscreen of the armrest to adjust the volume; they can use two fingers to pinch to zoom in and out; or they can make a swipe gesture in the air to switch to the next song or movie.

[0141] By installing control devices on the armrests of the vehicle seats, users can adjust the target content in the first display area based on the control devices. The operation panel can be reached by the user's arm hanging naturally, without having to lift their hand to operate the central control screen or find other buttons.

[0142] In some embodiments, the vehicle's control system may further include environmental parameter sensors.

[0143] In this embodiment, the environmental parameter sensor may include a photosensor (such as...) Figure 2 As shown in Figure 8, environmental parameter sensors can be installed on the top of the vehicle to collect current environmental parameters of the environment in which the vehicle is located.

[0144] For example, environmental parameter sensors can collect ambient light intensity in real time, and the data can be converted by an ADC (analog-to-digital converter, an electronic device used to convert continuous analog signals into discrete digital signals) and then input into the domain controller.

[0145] The environmental parameter sensor may also include a panoramic canopy integrated transparent photosensitive module (embedded in a glass interlayer), which can realize the integrated acquisition of illumination data and display area, or may include other types of sensors, which are not limited in this application.

This solves the problem that the lying posture information is not visible due to the independent functions of the seat and the display device, and improves the user experience.
