Description
Technical Field
[0001] This invention relates to the field of vehicle technology, and in particular to a display method and display device. Background Technology
[0002] In related technologies, the central control screen in the vehicle cabin can display simulated environmental images from different perspectives. These simulated environmental images refer to virtual visualizations rendered and displayed based on environmental data. However, when the simulated environmental images displayed on the central control screen need to switch from one perspective to another—for example, switching from a wide field of view in front of the vehicle in driving mode to a panoramic view of the vehicle's surroundings in parking mode—this is usually achieved through abrupt transitions, resulting in a choppy viewing experience and a poor user experience. Summary of the Invention
[0003] This application provides a display method and a display device.
[0004] This application provides a display method for a vehicle, the method comprising: Displays a simulated first environment view from a first virtual perspective; In response to a virtual viewpoint switching signal, determine the target virtual viewpoint; The system displays a first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint, and displays a second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint.
[0005] Thus, the display method provided in this application can display a first environment simulation screen under a first virtual perspective, and in response to a virtual perspective switching signal, determine a target virtual perspective, and display a first transition screen switching from the first virtual perspective to the target virtual perspective, and, when switching to the target virtual perspective, display a second environment simulation screen under the target virtual perspective. Compared to switching perspectives by jumping, this application embodiment can achieve a smooth transition of perspectives by displaying a first transition screen switching from the first virtual perspective to the target virtual perspective, avoiding abrupt jumps, and achieving a one-shot effect for the environment simulation screen, thereby improving the user experience to a certain extent.
[0006] In some embodiments, displaying a first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint, and displaying a second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint, includes: Generate a movement path based on the first virtual viewpoint and the target virtual viewpoint; Display a first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path; When switching to the target virtual viewpoint, the second environment simulation screen under the target virtual viewpoint is displayed.
[0007] Thus, a movement path is generated based on the first virtual viewpoint and the target virtual viewpoint; a first transition screen is displayed, showing the transition from the first virtual viewpoint to the target virtual viewpoint along the movement path; and when switching to the target virtual viewpoint, a second environment simulation screen under the target virtual viewpoint is displayed. In this way, by displaying the first transition screen, based on the movement path generated from the first virtual viewpoint and the target virtual viewpoint, a smooth transition of perspectives is achieved, ensuring the continuity of displayed information, thereby improving the user experience to a certain extent.
[0008] In some implementations, the virtual view switching signal includes a vehicle gear shifting signal, which indicates that the vehicle's gear is shifted from a first vehicle gear to a second vehicle gear. Determining the target virtual view in response to the virtual view switching signal includes: In response to the vehicle gear shifting signal, the virtual viewpoint corresponding to the second vehicle gear is determined as the target virtual viewpoint, wherein each vehicle gear corresponds to a virtual viewpoint.
[0009] Thus, in response to the vehicle gear shift signal, the virtual viewpoint corresponding to the second vehicle gear is indeed the target virtual viewpoint, where each vehicle gear corresponds to a virtual viewpoint. In this way, in response to the vehicle gear shift signal, the virtual viewpoint corresponding to the second vehicle gear can be determined as the target virtual viewpoint. This allows the virtual camera to be controlled to display a first transitional screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path corresponding to the first and target virtual views. This reduces user operations, ensures that the simulated second environment under the target virtual viewpoint matches the display requirements of the second vehicle gear, and thus improves the user experience.
[0010] In some embodiments, the virtual viewpoint switching signal further includes a vehicle state change signal, which indicates that the vehicle state is switching from a first vehicle state to a second vehicle state. The step of determining the target virtual viewpoint in response to the virtual viewpoint switching signal includes: In response to the vehicle state change signal, a second virtual perspective is determined as the target virtual perspective, wherein the environmental simulation screen under the second virtual perspective includes simulation content related to the second vehicle state.
[0011] In response to a vehicle state change signal, a second virtual viewpoint is determined as the target virtual viewpoint. The environmental simulation screen under the second virtual viewpoint contains simulated content related to the second vehicle state. Thus, in response to a vehicle state change signal indicating a switch from the first vehicle state to the second vehicle state, the second virtual viewpoint, capable of displaying simulated content related to the second vehicle state, can be determined as the target virtual viewpoint. This allows the virtual camera to be controlled to display a first transition screen showing the transition from the first virtual viewpoint to the target virtual viewpoint along the corresponding movement path, and, upon switching to the target virtual viewpoint, to display the second environmental simulation screen under the target virtual viewpoint. This reduces user operations, ensures that the second environmental simulation screen under the target virtual viewpoint contains simulated content related to the second vehicle state, and thereby improves the user experience.
[0012] In some implementations, the virtual view switching signal further includes a switching signal triggered by the target object, and determining the target virtual view in response to the virtual view switching signal includes: In response to the switching signal triggered by the target object, the target virtual viewpoint is determined.
[0013] Thus, in response to the switching signal triggered by the target object, the target virtual viewpoint is determined. Responding to the switching signal triggered by the target object, the target virtual viewpoint can be automatically adjusted according to the user's needs. This controls the virtual camera to display a first transitional screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path corresponding to the first virtual viewpoint and the target virtual viewpoint. This ensures that the displayed content matches the user's operational intent, meets the user's personalized needs, and enhances the user experience.
[0014] In some embodiments, the method further includes: When displaying the second environment simulation screen under the target virtual perspective, in response to a reset signal triggered by the target object, a second transition screen is displayed to switch from the target virtual perspective to the first virtual perspective, and when switching to the first virtual perspective, the first environment simulation screen under the first virtual perspective is displayed.
[0015] Thus, after moving from the first virtual viewpoint to the target virtual viewpoint, in response to a reset signal triggered by the target object, the viewpoint moves back to the first virtual viewpoint. This allows for the display of a second transition screen switching from the target virtual viewpoint to the first virtual viewpoint. Upon switching to the first virtual viewpoint, a first environmental simulation screen from that viewpoint is displayed, avoiding the perspective jump caused by a reset and ensuring a seamless, immersive interactive experience. This, in turn, fulfills the user's active reset needs and enhances the user experience.
[0016] In some embodiments, the method further includes: When displaying the second environment simulation screen under the target virtual perspective, if no vehicle status change signal or target object-triggered switching signal is received within a preset time threshold, a third transition screen is displayed to switch from the target virtual perspective to the first virtual perspective, and when switching to the first virtual perspective, the first environment simulation screen under the first virtual perspective is displayed.
[0017] Thus, when displaying the second environment simulation screen from the target virtual perspective, if no vehicle status change signal or target object-triggered switching signal is received within a preset time threshold, a third transition screen switching from the target virtual perspective to the first virtual perspective is displayed. Conversely, when switching to the first virtual perspective, the first environment simulation screen from the first virtual perspective is displayed. This active reset prevents the user from forgetting to reset, thus avoiding a prolonged non-standard viewing angle and ensuring perspective adaptability and information integrity, thereby improving the user experience to some extent.
[0018] In some implementations, the virtual view switching signal includes a vehicle gear shifting signal, a vehicle state change signal, and a switching signal triggered by the target object. Determining the target virtual view in response to the virtual view switching signal includes: When at least two of the following signals are obtained: the vehicle gear shift signal, the vehicle state change signal, and the switching signal triggered by the target object, a target signal is determined from the at least two signals according to the first preset priority corresponding to the vehicle gear shift signal, the second preset priority corresponding to the vehicle state change signal, and the third preset priority corresponding to the switching signal triggered by the target object. The virtual viewpoint of the target is determined based on the target signal.
[0019] Thus, when at least two of the following signals are received: vehicle gear shift signal, vehicle status change signal, and target object-triggered switching signal, the target signal is determined from these two signals based on a first preset priority corresponding to the vehicle gear shift signal, a second preset priority corresponding to the vehicle status change signal, and a third preset priority corresponding to the target object-triggered switching signal. Based on the target signal, the target virtual viewpoint is determined. In this way, by clearly defining priority rules, the problem of multiple signal conflicts can be resolved when multiple signals are triggered concurrently, ensuring driving safety while meeting the personalized needs of users.
[0020] In some embodiments, the method further includes: In response to the launch command of the target application, the application interface of the target application is displayed in a sub-area of the currently displayed environment simulation screen.
[0021] In response to the target application's launch command, the application interface of the target application is displayed in a sub-region of the currently displayed environment simulation screen. This allows for real-time response to the target application's launch command, determining the position and size of the sub-region based on the target application and the content distribution of the current environment simulation screen, and then displaying the target application's interface within that sub-region. This enables simultaneous acquisition of vehicle surroundings and functional information, improving interaction efficiency and reducing the number of times the driver's gaze needs to shift during driving, thereby enhancing user experience and driving safety to some extent.
[0022] This application provides a vehicle including a memory and a processor. The memory stores a computer program, which, when executed by the processor, implements the steps of the above-described method.
[0023] This application provides a computer-readable storage medium storing a computer program that, when executed by one or more processors, implements the steps of the above-described method.
[0024] The display device, vehicle, and computer-readable storage medium provided in this application embodiment display a first environment simulation screen under a first virtual viewpoint; determine a target virtual viewpoint in response to a virtual viewpoint switching signal; display a first transition screen switching from the first virtual viewpoint to the target virtual viewpoint; and display a second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint. This allows for displaying the first environment simulation screen under the first virtual viewpoint, determining the target virtual viewpoint in response to a virtual viewpoint switching signal, displaying the first transition screen switching from the first virtual viewpoint to the target virtual viewpoint, and displaying the second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint. Compared to switching viewpoints abruptly, this application embodiment achieves a smooth transition of viewpoints by displaying the first transition screen switching from the first virtual viewpoint to the target virtual viewpoint, avoiding abrupt jumps and achieving a one-shot effect for the environment simulation screen, thereby improving the user experience to a certain extent.
[0025] Additional aspects and advantages of embodiments of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of embodiments of this application. Attached Figure Description

Detailed Implementation
[0027] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.
[0028] In related technologies, the central control screen in the vehicle cabin can display simulated environmental images rendered and displayed based on environmental data from different perspectives, such as a lane-level overhead view when driving and a panoramic view when parking.
[0029] However, when the environmental simulation screen displayed on the central control screen needs to switch from one perspective to another, it is usually done by jumping. For example, when switching from the wide field of view in front of the vehicle in driving mode to the panoramic view of the vehicle's surroundings in parking mode, the environmental simulation screen in one perspective will be instantly replaced by the environmental simulation screen in the other perspective. The switching process is rather abrupt and the user experience is poor.
[0030] Based on the above issues, please refer to Figure 1 This application provides a display method for a vehicle, the method comprising: 01: Displays the first environment simulation screen from the first virtual perspective; 02: In response to the virtual viewpoint switching signal, determine the target virtual viewpoint; 03: Display the first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint, and display the second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint.
[0031] This application provides a display device. The display method of this application can be implemented by the display device of this application. Specifically, the display device includes a display module and a determination module. The display module is used to display a first environment simulation screen under a first virtual viewpoint. The determination module is used to determine a target virtual viewpoint in response to a virtual viewpoint switching signal. The display module is also used to display a first transition screen switching from the first virtual viewpoint to the target virtual viewpoint, and, when switching to the target virtual viewpoint, to display a second environment simulation screen under the target virtual viewpoint.
[0032] This application also provides a vehicle, which includes a display, a memory, and a processor. The display method of this application can be implemented by the electronic device of this application. Specifically, the memory stores a computer program, and the processor is used to control the display to show a first environment simulation screen under a first virtual viewpoint. The processor is also used to determine a target virtual viewpoint in response to a virtual viewpoint switching signal. The processor is also used to control the display to show a first transition screen switching from the first virtual viewpoint to the target virtual viewpoint, and to show a second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint.
[0033] Specifically, virtual perspective refers to the virtual camera observation angle that simulates the vehicle and its surrounding environment on the display device (such as the central control screen) in the vehicle cabin, such as the lane-level overhead view when driving and the panoramic view when parking.
[0034] The virtual environment simulation screen is a visual interface that integrates the vehicle's 3D model, real-time vehicle status information (such as tire pressure and battery level), and simulated display of the surrounding environment (such as lanes and obstacles).
[0035] The first environment simulation screen in the first virtual perspective refers to the initial visualization interface in the initial virtual perspective corresponding to the current vehicle.
[0036] The second environment simulation screen under the target virtual perspective is the observation angle and corresponding visualization content that needs to be presented after the switch, which matches the perspective switching signal.
[0037] The first transition screen is the intermediate screen displayed during the process of switching from the first virtual perspective to the target virtual perspective.
[0038] Understandably, the environmental simulation screen is a visual interface generated by analyzing at least one of the vehicle's gear information, vehicle status information, and vehicle environmental information, allowing users to obtain multiple types of information in the same screen.
[0039] Vehicle gear refers to the vehicle's current operating gear, such as park (P), drive (D), and reverse (R); vehicle status refers to the vehicle's current state, including information such as the vehicle's current operating mode and working status, such as charging status, navigation activation status, autonomous driving mode, and safety warning status; vehicle environmental information refers to real-time environmental data collected by the vehicle around it, including information such as road distribution, obstacles, the positions of surrounding vehicles, and road signs.
[0040] When vehicle gear and vehicle status information change, the current first virtual view and the simulated environment within that view may change accordingly. For example, the view in driving mode focuses on a wide field of view in front of the vehicle and simultaneously displays the lane-level scene, while the view in parking mode focuses on a panoramic view of the vehicle's surroundings. Furthermore, users can actively switch virtual views. Therefore, signals generated by gear shifting, changes in vehicle status, and user-triggered view switching can be considered virtual view switching signals to trigger perspective changes.
[0041] In response to a virtual viewpoint switching signal, it can be determined that a target virtual viewpoint needs to be displayed, so as to switch the current virtual camera's viewpoint from the first virtual viewpoint to the target virtual viewpoint.
[0042] Since the first virtual viewpoint corresponds to the first environment simulation screen and the target virtual viewpoint corresponds to the second environment simulation screen, during the process of the current virtual camera's viewpoint switching from the first virtual viewpoint to the target virtual viewpoint, by displaying the first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint, a gradual transition from the first environment simulation screen to the second environment simulation screen can be achieved, so that when switching to the target virtual viewpoint, the second environment simulation screen under the target virtual viewpoint is displayed.
[0043] In one example, with the vehicle in Park (P) gear, the display is as follows: Figure 2 The virtual view shown focuses on the panoramic view around the vehicle and displays vehicle status information such as tire pressure. It can also overlay environmental simulation display content such as the relative position of the vehicle with the surrounding parking lines and adjacent vehicles.
[0044] In one example, with the vehicle in Drive (D) gear, the display is as follows: Figure 3 The virtual view shown focuses on a wide field of view in front of the vehicle, and simultaneously displays lane-level scenes, navigation paths, and real-time vehicle status, such as the current lane, adjacent lanes, and other environmental simulation content.
[0045] In one example, when the vehicle shifts from P to D gear, the first virtual view could be... Figure 2 The panoramic view shown focuses on the area around the vehicle; the target virtual view can be... Figure 3 The wide field of view shown focuses on the view in front of the vehicle, and the virtual camera view can be adjusted. Figure 2 The first virtual view shown moves to Figure 3 The target virtual view shown is displayed, and a first transition screen is shown that switches from the first virtual view to the target virtual view.
[0046] Understandably, in other examples, the first virtual viewpoint can be any viewpoint in the foregoing embodiments, and the target virtual viewpoint can be any viewpoint different from the first virtual viewpoint in the foregoing embodiments, so that when a virtual viewpoint switching signal is received, full viewpoint switching in multiple scenarios can be realized, and the first transition screen of viewpoint switching can be displayed.
[0047] In addition, in display Figure 2 In the simulated environment shown in the virtual perspective, the user can also move the viewpoint by dragging the image; the virtual camera viewpoint is self-contained. Figure 2 The first virtual viewpoint moves to the user's desired viewpoint (target virtual viewpoint) and displays the first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint, ultimately achieving a seamless, immersive interactive experience.
[0048] Compared to switching perspectives by jumping around, the implementation method of this application can achieve a smooth transition of perspectives by displaying a first transition screen that switches from the first virtual perspective to the target virtual perspective, avoiding abrupt jumps and achieving a one-shot effect for the environmental simulation screen, thereby improving the user experience to a certain extent.
[0049] In addition, based on the actual usage scenario of the vehicle, it can automatically respond to virtual perspective switching signals such as vehicle gear shifting, vehicle status changes, and perspective switching signals triggered by the user, in order to determine the target virtual perspective to be switched and display the first transition screen, ensuring that the target virtual perspective scenario requirements are matched, as well as the timeliness and accuracy of perspective switching, thereby improving the user's driving experience.
[0050] In summary, the display method provided by this application can display a first environment simulation screen under a first virtual perspective, and, in response to a virtual perspective switching signal, determine a target virtual perspective, and display a first transition screen switching from the first virtual perspective to the target virtual perspective, and, when switching to the target virtual perspective, display a second environment simulation screen under the target virtual perspective. Compared to switching perspectives by jumping, this application's embodiment can achieve a smooth transition of perspectives by displaying a first transition screen switching from the first virtual perspective to the target virtual perspective, avoiding abrupt jumps, and achieving a one-shot effect for the environment simulation screen, thereby improving the user experience to a certain extent.
[0051] Please see Figure 4 In some embodiments, step 03 (displaying a first transition screen switching from a first virtual viewpoint to a target virtual viewpoint, and displaying a second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint) includes: 031: Generate a movement path based on the first virtual viewpoint and the target virtual viewpoint; 032: Display the first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path; 033: When switching to the target virtual view, display the second environment simulation screen under the target virtual view.
[0052] In some implementations, the determining module is further configured to generate a movement path based on the first virtual viewpoint and the target virtual viewpoint. The display module is further configured to display a first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path. The display module is further configured to display a second environment simulation screen under the target virtual viewpoint when switching to the target virtual viewpoint.
[0053] In some implementations, the processor is further configured to generate a movement path based on a first virtual viewpoint and a target virtual viewpoint. The processor is also configured to control the display to show a first transition screen showing the transition from the first virtual viewpoint to the target virtual viewpoint along the movement path. The processor is further configured to control the display to show a second environmental simulation screen under the target virtual viewpoint when the viewpoint is switched to.
[0054] Specifically, the movement path is a continuous trajectory generated by an algorithm, in which the virtual camera viewpoint moves from the first virtual viewpoint to the target virtual viewpoint.
[0055] Based on the parameter differences between the current first virtual viewpoint and the target virtual viewpoint to be displayed later, such as the viewpoint spatial coordinates, pitch angle, field of view, and zoom ratio, a movement path can be generated starting from the first virtual viewpoint and ending at the target virtual viewpoint.
[0056] Based on the parameters of each frame of the movement path, the virtual camera parameters can be adjusted in real time to calculate the content under the current view of the virtual camera, so as to generate continuous dynamic images. This allows users to observe the smooth movement and natural gradation of the view along the path until the virtual camera parameters match the target virtual view. At this point, the path movement stops, and the second environment simulation image is rendered and fixed to avoid abrupt changes in the image.
[0057] In one example, a smooth transition algorithm can be used to move the virtual camera's viewpoint, thus achieving a smooth transition between the first virtual viewpoint and the target virtual viewpoint.
[0058] Based on the damped cosine easing function, the transition curve is controlled by three parameters: damping coefficient, frequency coefficient, and easing exponent. Interpolation calculations are performed in the rendering loop to achieve smooth interpolation of camera parameters and ensure a smooth and natural transition of viewpoint.
[0059] It should be noted that the values of parameters such as damping coefficient, frequency coefficient, and easing index are not fixed and can be adjusted according to different viewing angles and scenes to automatically respond to scene changes, ensure the timeliness and accuracy of viewing angle switching, and the continuity of display.
[0060] Compared to switching perspectives by jumping, the implementation method of this application can display a first transition screen that switches from the first virtual perspective to the target virtual perspective along the movement path generated based on the first virtual perspective and the target virtual perspective, thereby achieving a smooth connection of perspectives and ensuring the continuity of displayed information, thus improving the user experience to a certain extent.
[0061] Thus, a movement path is generated based on the first virtual viewpoint and the target virtual viewpoint; a first transition screen is displayed, showing the transition from the first virtual viewpoint to the target virtual viewpoint along the movement path; and when switching to the target virtual viewpoint, a second environment simulation screen under the target virtual viewpoint is displayed. In this way, by displaying the first transition screen, based on the movement path generated from the first virtual viewpoint and the target virtual viewpoint, a smooth transition of perspectives is achieved, ensuring the continuity of displayed information, thereby improving the user experience to a certain extent.
[0062] Please see Figure 5In some implementations, the virtual view switching signal includes a vehicle gear shifting signal, which indicates that the vehicle's gear is shifted from a first vehicle gear to a second vehicle gear. Step 02 (determining the target virtual view in response to the virtual view switching signal) includes: 021: In response to the vehicle gear shifting signal, determine the virtual viewpoint corresponding to the second vehicle gear as the target virtual viewpoint, wherein each vehicle gear corresponds to a virtual viewpoint.
[0063] In some implementations, the determining module is further configured to determine, in response to a vehicle gear shifting signal, a virtual viewpoint corresponding to a second vehicle gear as a target virtual viewpoint, wherein each vehicle gear corresponds to a virtual viewpoint.
[0064] In some implementations, the processor is further configured to, in response to a vehicle gear shifting signal, determine a virtual viewpoint corresponding to a second vehicle gear as a target virtual viewpoint, wherein each vehicle gear corresponds to a virtual viewpoint.
[0065] Specifically, the vehicle gear shift signal is an electrical signal generated after the vehicle gear shifts from the first vehicle gear to the second vehicle gear. For example, triggering the vehicle gear lever or electronic gear button can generate the vehicle gear shift signal, which can be used to trigger the viewpoint switch.
[0066] The first vehicle gear position is the gear state the vehicle is in before the viewpoint switch; the second vehicle gear position is the gear position after the vehicle gear switch, which is different from the first vehicle gear position. Each vehicle gear position corresponds to a virtual viewpoint, that is, when the vehicle is in the first vehicle gear position, it corresponds to a virtual viewpoint, and the virtual viewpoint corresponding to the first vehicle gear position is the first virtual viewpoint; when switching to the second vehicle gear position, the virtual viewpoint corresponding to the first vehicle gear position becomes the target virtual viewpoint.
[0067] Understandably, each vehicle gear is pre-configured with a corresponding virtual view. This virtual view serves as the default display reference for the corresponding vehicle gear, so that subsequent view switching is based on the virtual view corresponding to that vehicle gear.
[0068] By providing a stable display benchmark for different vehicle gears to adapt to different driving scenarios, the frequent changes in viewing angle at the same gear can be avoided from affecting the user experience, thereby ensuring the stability of the display within the same vehicle gear.
[0069] In response to the vehicle gear shift signal, the virtual viewpoint corresponding to the second vehicle gear can be determined as the target virtual viewpoint. This allows the virtual camera to be controlled to move along the movement path corresponding to the first virtual viewpoint and the target virtual viewpoint, displaying a first transitional screen that switches from the first virtual viewpoint to the target virtual viewpoint. This reduces user operations, ensures that the simulated second environment screen under the target virtual viewpoint matches the display requirements of the second vehicle gear, and thus improves the user experience.
[0070] Thus, in response to the vehicle gear shift signal, the virtual viewpoint corresponding to the second vehicle gear is indeed the target virtual viewpoint, where each vehicle gear corresponds to a virtual viewpoint. In this way, in response to the vehicle gear shift signal, the virtual viewpoint corresponding to the second vehicle gear can be determined as the target virtual viewpoint. This allows the virtual camera to be controlled to display a first transitional screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path corresponding to the first and target virtual views. This reduces user operations, ensures that the simulated second environment under the target virtual viewpoint matches the display requirements of the second vehicle gear, and thus improves the user experience.
[0071] Please see Figure 6 In some embodiments, the virtual view switching signal further includes a vehicle state change signal, which indicates that the vehicle state has switched from a first vehicle state to a second vehicle state. Step 02 (determining the target virtual view in response to the virtual view switching signal) includes: 022: In response to the vehicle status change signal, the second virtual viewpoint is determined as the target virtual viewpoint, wherein the environmental simulation screen under the second virtual viewpoint contains simulation content related to the second vehicle status.
[0072] In some implementations, the determining module is further configured to determine the second virtual viewpoint as the target virtual viewpoint in response to a vehicle state change signal, wherein the environmental simulation screen under the second virtual viewpoint includes simulation content related to the second vehicle state.
[0073] In some implementations, the processor is further configured to determine a second virtual viewpoint as a target virtual viewpoint in response to a vehicle state change signal, wherein the environmental simulation screen under the second virtual viewpoint includes simulation content related to the second vehicle state.
[0074] Specifically, the vehicle status change signal is an electrical signal generated by the real-time change of vehicle operation data, i.e., the switch from the first vehicle status to the second vehicle status, which can be used to trigger the viewpoint switch.
[0075] The first vehicle state is the state of the vehicle before the viewpoint is switched; the second vehicle state is the state after the vehicle state changes and is different from the first vehicle state, such as switching from navigation mode (first vehicle state) to cruise mode (second vehicle state) in D gear.
[0076] Understandably, when the vehicle's state switches from the first vehicle state to the second vehicle state, the vehicle state information displayed in the environmental simulation screen will also change accordingly. This is achieved by displaying a transition screen showing the virtual viewpoint switch, and an environmental simulation screen after the viewpoint switch is complete, to inform the user of the changed vehicle state information. The simulation content related to the second vehicle state is the visual information related to the second vehicle state displayed in the environmental simulation screen under the second virtual viewpoint.
[0077] In response to a vehicle state change signal that switches from a first vehicle state to a second vehicle state, a second virtual viewpoint capable of displaying simulated content related to the second vehicle state can be determined as the target virtual viewpoint. The virtual camera is then controlled to display a first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path corresponding to the second virtual viewpoint and the target virtual viewpoint. When switching to the target virtual viewpoint, a second environment simulation screen under the target virtual viewpoint is displayed, reducing user operations and ensuring that the second environment simulation screen under the target virtual viewpoint contains simulated content related to the second vehicle state, thereby improving the user experience.
[0078] It should be noted that the vehicle state in the embodiments of this application can be subdivided according to the actual use scenario. For changes in the vehicle state, the target virtual perspective can be determined by the combination of parameter conditions corresponding to the vehicle state before and after the change, so as to ensure that the second environment simulation screen under the target virtual perspective contains simulation content related to the second vehicle state.
[0079] In one example, such as Figure 7 In the virtual perspective shown (first virtual perspective), the vehicle is in navigation mode, and the simulated environment displayed corresponds to a slightly higher viewing angle, such as... Figure 8 In the virtual perspective shown (target virtual perspective), the vehicle changes from navigation mode to cruise mode, and the corresponding perspective of the displayed environment simulation screen is slightly lower.
[0080] Thus, in response to a vehicle state change signal, a second virtual viewpoint is determined as the target virtual viewpoint, wherein the environmental simulation screen under the second virtual viewpoint contains simulation content related to the second vehicle state. In this way, in response to a vehicle state change signal switching from the first vehicle state to the second vehicle state, the second virtual viewpoint, capable of displaying simulation content related to the second vehicle state, can be determined as the target virtual viewpoint. This allows the virtual camera to be controlled to display a first transition screen switching from the first virtual viewpoint to the target virtual viewpoint along the corresponding movement path, and, upon switching to the target virtual viewpoint, to display the second environmental simulation screen under the target virtual viewpoint. This reduces user operations, ensures that the second environmental simulation screen under the target virtual viewpoint contains simulation content related to the second vehicle state, and thereby improves the user experience.
[0081] Please see Figure 9 In some implementations, the virtual view switching signal also includes a switching signal triggered by the target object. Step 02 (in response to the virtual view switching signal, determining the target virtual view) includes: 023: In response to a switching signal triggered by the target object, determine the target's virtual viewpoint.
[0082] In some implementations, the determining module is also used to determine the target virtual viewpoint in response to a switching signal triggered by the target object.
[0083] In some implementations, the processor is also configured to determine the target virtual viewpoint in response to a switching signal triggered by the target object.
[0084] Specifically, the target object refers to the user inside the vehicle's cabin. The switching signal is a signal triggered by the target object that can adjust the virtual camera's perspective. This can be an electrical signal generated by user touch operations (such as dragging the simulated environment on the central control screen), voice commands (such as "zoom in on the map"), gesture operations, and button operations, used to personalize the perspective adjustment.
[0085] In response to a switching signal triggered by the target object, the target virtual viewpoint can be automatically adjusted according to the user's needs. This controls the virtual camera to move along the path corresponding to the first virtual viewpoint and the target virtual viewpoint, displaying the first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint. This ensures that the displayed content matches the user's operational intent, meets the user's personalized needs, and improves the user experience.
[0086] Furthermore, the target object can trigger an application launch signal to display the desired application on the screen, and in multi-tasking scenarios, lane-level avoidance can be achieved, such as... Figure 10 The simulated environment shown is displayed when the user opens an application ( Figure 10(In the left-hand APP area), the camera smoothly moves to the right horizontally to avoid the application obscuring the vehicle model or information, further enhancing the user experience.
[0087] Thus, in response to the switching signal triggered by the target object, the target virtual viewpoint is determined. Responding to the switching signal triggered by the target object, the target virtual viewpoint can be automatically adjusted according to the user's needs. This controls the virtual camera to display a first transitional screen that switches from the first virtual viewpoint to the target virtual viewpoint along the movement path corresponding to the first virtual viewpoint and the target virtual viewpoint. This ensures that the displayed content matches the user's operational intent, meets the user's personalized needs, and enhances the user experience.
[0088] Please see Figure 11 In some implementations, the method further includes: 024: When displaying a second environment simulation screen under the target virtual view, in response to a reset signal triggered by the target object, a second transition screen is displayed to switch from the target virtual view to the first virtual view, and when switching to the first virtual view, a first environment simulation screen under the first virtual view is displayed.
[0089] In some embodiments, the display module is further configured to, in response to a reset signal triggered by the target object, display a second transition screen switching from the target virtual viewpoint to the first virtual viewpoint when displaying a second environment simulation screen under the target virtual viewpoint, and display a first environment simulation screen under the first virtual viewpoint when switching to the first virtual viewpoint.
[0090] In some embodiments, the processor is further configured to, in response to a reset signal triggered by the target object, control the display to display a second transition screen that switches from the target virtual viewpoint to the first virtual viewpoint when displaying a second environment simulation screen under the target virtual viewpoint, and to display a first environment simulation screen under the first virtual viewpoint when switching to the first virtual viewpoint.
[0091] Specifically, the reset signal is the instruction signal that returns the viewpoint to the initial viewpoint (from the current target virtual viewpoint back to the first virtual viewpoint).
[0092] The second transition screen is an intermediate screen displayed during the transition from the target virtual viewpoint to the first virtual viewpoint, and its rendering logic is the same as that of the first transition screen.
[0093] After moving from the first virtual viewpoint to the target virtual viewpoint, a second environment simulation screen from the target virtual viewpoint will be displayed. By triggering a reset signal, the user can display a second transition screen that switches from the target virtual viewpoint back to the first virtual viewpoint. When switching back to the first virtual viewpoint, the first environment simulation screen from the first virtual viewpoint will be displayed, avoiding the perspective jump caused by the reset and ensuring a seamless, immersive interactive experience. This allows the user to actively reset their viewpoint and improves the user experience.
[0094] It should be noted that the reset signal only resets the view switching based on the virtual view corresponding to the vehicle gear. It can be understood that when the vehicle gear remains unchanged, the first virtual view switched by the vehicle state change signal and the user-triggered switching signal is the virtual view corresponding to the current vehicle gear. Regardless of how many times the virtual view is switched in response to the vehicle state change signal and the user-triggered switching signal, such as switching the first virtual view to the first target virtual view and then switching the first target virtual view to the second target virtual view, in response to the reset signal, the final target virtual view will be switched back to the first virtual view corresponding to the current vehicle gear.
[0095] In the event of a vehicle gear shift, in response to a vehicle gear shift signal indicating a shift from the first vehicle gear to the second vehicle gear, the first virtual view is switched to the second virtual view (target virtual view) corresponding to the second vehicle gear, and no reset is required.
[0096] Thus, after moving from the first virtual viewpoint to the target virtual viewpoint, in response to a reset signal triggered by the target object, the viewpoint moves back to the first virtual viewpoint. This allows for the display of a second transition screen switching from the target virtual viewpoint to the first virtual viewpoint. Upon switching to the first virtual viewpoint, a first environmental simulation screen from that viewpoint is displayed, avoiding the perspective jump caused by a reset and ensuring a seamless, immersive interactive experience. This, in turn, fulfills the user's active reset needs and enhances the user experience.
[0097] Please see Figure 12 In some implementations, the method further includes: 025: When displaying the second environment simulation screen under the target virtual perspective, if no vehicle status change signal or target object-triggered switching signal is received within a preset time threshold, a third transition screen is displayed to switch from the target virtual perspective to the first virtual perspective, and when switching to the first virtual perspective, the first environment simulation screen under the first virtual perspective is displayed.
[0098] In some embodiments, the display module is further configured to, when displaying a second environment simulation screen under the target virtual perspective, if no vehicle state change signal or target object-triggered switching signal is received within a preset time threshold, display a third transition screen switching from the target virtual perspective to the first virtual perspective, and when switching to the first virtual perspective, display a first environment simulation screen under the first virtual perspective.
[0099] In some embodiments, the processor is further configured to control the display to display a third transition screen switching from the target virtual viewpoint to the first virtual viewpoint if no vehicle state change signal or target object-triggered switching signal is received within a preset time threshold when displaying a second environment simulation screen under the target virtual viewpoint, and to display a first environment simulation screen under the first virtual viewpoint when switching to the first virtual viewpoint.
[0100] Specifically, the preset time threshold is a pre-configured automatic reset waiting time, which can be dynamically adjusted according to the actual situation, and is not limited here.
[0101] When displaying the first transition screen that switches from the first virtual viewpoint to the target virtual viewpoint, and when switching to the target virtual viewpoint, the automatic reset timer can be activated, and new signals such as vehicle status change signals and switching signals can be continuously detected.
[0102] If no vehicle status change signal or switching signal is received within the preset time threshold, the conditions for automatic reset are met, similar to the reset signal triggered by the target object mentioned above. The target virtual view is moved to the first virtual view. Please refer to the steps for the reset signal triggered by the target object mentioned above, which will not be repeated here.
[0103] By actively resetting the viewpoint, the user's perspective can be kept in a non-standard state for a long time due to forgetting to reset, thus ensuring viewpoint adaptability and information integrity and improving the user experience to a certain extent.
[0104] Thus, when displaying the second environment simulation screen from the target virtual perspective, if no vehicle status change signal or target object-triggered switching signal is received within a preset time threshold, a third transition screen switching from the target virtual perspective to the first virtual perspective is displayed. Conversely, when switching to the first virtual perspective, the first environment simulation screen from the first virtual perspective is displayed. This active reset prevents the user from forgetting to reset, thus avoiding a prolonged non-standard viewing angle and ensuring perspective adaptability and information integrity, thereby improving the user experience to some extent.
[0105] Please see Figure 13In some implementations, the virtual view switching signal includes a vehicle gear shifting signal, a vehicle state change signal, and a switching signal triggered by the target object. Step 02 (determining the target virtual view in response to the virtual view switching signal) includes: 026: When at least two of the following signals are obtained: vehicle gear shifting signal, vehicle status change signal, and target object triggered switching signal, the target signal is determined from the at least two signals according to the first preset priority corresponding to the vehicle gear shifting signal, the second preset priority corresponding to the vehicle status change signal, and the third preset priority corresponding to the target object triggered switching signal. 027: Determine the virtual viewpoint of the target based on the target signal.
[0106] In some embodiments, the determining module is further configured to, when at least two of the following signals are acquired—a vehicle gear shifting signal, a vehicle state change signal, and a target object-triggered switching signal—determine a target signal from the at least two signals according to a first preset priority corresponding to the vehicle gear shifting signal, a second preset priority corresponding to the vehicle state change signal, and a third preset priority corresponding to the target object-triggered switching signal. The determining module is also configured to determine the target virtual viewpoint based on the target signal.
[0107] In some embodiments, the processor is further configured to, upon acquiring at least two of the following signals—a vehicle gear shift signal, a vehicle state change signal, and a target object-triggered switching signal—determine a target signal from the at least two signals according to a first preset priority corresponding to the vehicle gear shift signal, a second preset priority corresponding to the vehicle state change signal, and a third preset priority corresponding to the target object-triggered switching signal. The processor is also configured to determine a target virtual viewpoint based on the target signal.
[0108] Specifically, the preset view switching conditions include acquiring a vehicle gear shift signal, a vehicle state change signal, and a switching signal triggered by a target object. When at least two of the vehicle gear shift signal, vehicle state change signal, and switching signal are acquired, i.e., when multiple signals are triggered concurrently, the signal with higher priority can be determined as the target signal based on the priority of each signal and the preset priority rules, so as to determine the target virtual view to be converted subsequently based on the target signal; if there are signals with the same priority, they are triggered sequentially in chronological order.
[0109] In one example, the priority of vehicle gear shifting signals, vehicle status change signals, and safety-related signals among the switching signals can be set to the highest priority. This ensures that safety requirements (such as obstacle warnings and collision risk alerts) can be presented as soon as possible by adjusting the viewing angle, or even interrupting the normal viewing angle display state, thereby reducing safety hazards caused by the failure to adapt the viewing angle in time.
[0110] By clearly defining priority rules, the problem of multiple signal conflicts can be resolved when multiple signals are triggered concurrently, thus ensuring driving safety while meeting users' personalized needs.
[0111] Thus, when at least two of the following signals are received: vehicle gear shift signal, vehicle status change signal, and target object-triggered switching signal, the target signal is determined from these two signals based on a first preset priority corresponding to the vehicle gear shift signal, a second preset priority corresponding to the vehicle status change signal, and a third preset priority corresponding to the target object-triggered switching signal. Based on the target signal, the target virtual viewpoint is determined. In this way, by clearly defining priority rules, the problem of multiple signal conflicts can be resolved when multiple signals are triggered concurrently, ensuring driving safety while meeting the personalized needs of users.
[0112] Please see Figure 14 In some implementations, the method further includes: 04: In response to the launch command of the target application, display the application interface of the target application in a sub-area of the currently displayed environment simulation screen.
[0113] In some implementations, the display module is also used to display the application interface of the target application in a sub-region of the currently displayed environment simulation screen in response to the launch command of the target application.
[0114] In some implementations, the processor is also configured to control the display to show the application interface of the target application in a sub-region of the currently displayed environment simulation screen in response to a launch command of the target application.
[0115] Specifically, the target applications are various functional applications that users need to activate in the vehicle cabin scenario, such as music playback, air conditioning control, telephone communication, vehicle settings, weather inquiry, and other functional applications.
[0116] The launch command for the target application refers to the signal triggered by the user through cockpit interaction to activate the target application.
[0117] A sub-region refers to an independent interactive area within the overall display area of the environment simulation screen that does not obscure environmental information. The size and position of the sub-region can be dynamically adapted based on the application type and the information distribution of the environment screen.
[0118] In response to the target application's launch command, the target application's interface is displayed in a sub-area of the currently displayed environment simulation screen.
[0119] During any stage of displaying the first environment simulation screen, the transition screen, or the second environment simulation screen, it can respond in real time to the launch command of the target application, determine the position and size of the sub-region based on the content distribution of the target application and the current environment simulation screen, and then display the application interface of the target application in the sub-region of the currently displayed environment simulation screen. This enables the simultaneous acquisition of vehicle surrounding information and functional information, improves interaction efficiency, reduces the number of times the eyes need to be shifted in driving scenarios, and improves user experience and driving safety to a certain extent.
[0120] Furthermore, while rendering the target application's interface in the sub-region, the current environmental simulation can be updated in real time. For example, the viewpoint adjusts as the vehicle moves and vehicle status data is refreshed in real time, ensuring that the environmental simulation remains undisturbed. If the user triggers a virtual viewpoint switching signal, the system will prioritize the viewpoint switching process, and the sub-region will transition synchronously with the environmental screen, ensuring display continuity.
[0121] In response to the target application's launch command, the application interface of the target application is displayed in a sub-region of the currently displayed environment simulation screen. This allows for real-time response to the target application's launch command, determining the position and size of the sub-region based on the target application and the content distribution of the current environment simulation screen, and then displaying the target application's interface within that sub-region. This enables simultaneous acquisition of vehicle surroundings and functional information, improving interaction efficiency and reducing the number of times the driver's gaze needs to shift during driving, thereby enhancing user experience and driving safety to some extent.
