[0061] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0062] The vehicle projection control method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the controller of the vehicle screen, the vehicle projection device, and the terminal can communicate with each other. When the controller raises or lowers the vehicle screen, or when the terminal adjusts the application information for projection, the other party can make corresponding adaptive adjustments based on the adjustment or operation. The vehicle projection device can project the application adapted to the current unfolding ratio of the vehicle screen onto the vehicle screen based on the application information sent by the controller or terminal of the vehicle screen.

[0063] In one exemplary embodiment, such as Figure 2 As shown, a vehicle-mounted projection control method is provided, which is applied to... Figure 1 Taking a vehicle-mounted projection device as an example, the explanation includes the following steps S202 to S204. Wherein:

[0064] Step S202: Project the first projection image of the target application onto the vehicle screen with a first unfolding ratio; the layout of the content of the first projection image is adapted to the first unfolding ratio.

[0065] The vehicle can be equipped with a vehicle-mounted screen and a vehicle-mounted projection device. The vehicle-mounted projection device can use laser projection technology to project images onto the vehicle-mounted screen. The screen supports electric lifting and retraction, and can be infinitely adjusted in height or customized with multiple fixed positions to meet various display needs. The installation method of the vehicle-mounted screen and projection device can be as follows: Figure 3 As shown, Figure 3This is a schematic diagram of the interior structure of a vehicle in one embodiment. The vehicle-mounted screen can be installed on the roof between the front and rear rows of the vehicle, and the vehicle projection equipment can be installed on the roof behind the rear rows or at other locations within the vehicle where it can project onto the vehicle-mounted screen. This allows rear passengers to watch images projected onto the vehicle-mounted screen from their seats.

[0066] The raising and lowering of the vehicle-mounted screen can be controlled via a controller or by voice commands. The target application can be an application within a terminal that requires projection; this terminal can be a standalone mobile terminal or an in-vehicle terminal integrated into the vehicle. The in-vehicle projection device can project the target application's image from the terminal. For example, the in-vehicle projection device can project the first projection image of the target application onto the in-vehicle screen at a first unfolding ratio. The in-vehicle screen needs to be unfolded before the in-vehicle projection device can project the image. The unfolding ratio of the in-vehicle screen can be determined based on the layout of the target application's image content, and this layout can also be adaptively adjusted based on the unfolding ratio. The image content layout of the first projection image is adapted to the first unfolding ratio.

[0067] The screen content layout can be the layout of various contents in the screen when the target application is projected onto the vehicle screen. The screen content layout can be adjusted according to the unfolding ratio of the vehicle screen, and the unfolding ratio of the vehicle screen can also be adjusted based on the specified screen content layout selected by the target application.

[0068] Step S204: In response to the projection adjustment command, the second projection screen of the target application is projected onto the vehicle screen with the second unfolding ratio; the layout of the content of the second projection screen is adapted to the second unfolding ratio; the first unfolding ratio is different from the second unfolding ratio.

[0069] The projection adjustment command can be an instruction to change the projected image. Specifically, it can be issued to adjust a target application on the terminal or a vehicle-mounted screen. In response to this projection adjustment command, the terminal, vehicle-mounted projection device, and controller can make corresponding adjustments based on different commands, thus re-adapting the unfolding ratio of the vehicle-mounted screen to the layout of the target application's image content. For example, if the first projection image of the target application is projected onto a vehicle-mounted screen with a first unfolding ratio, the vehicle-mounted projection device, in response to the projection adjustment command, can project the second projection image of the target application onto a vehicle-mounted screen with a second unfolding ratio. The layout of the second projection image can be adapted to the second unfolding ratio, and the first and second unfolding ratios are different.

[0070] If the projection adjustment command is an adjustment command for a target application, indicating that the new target application needs to be projected onto the vehicle screen, the terminal can determine the screen content layout of the target application, and the vehicle projection device can control the vehicle screen to rise and fall from the first unfolding ratio to the second unfolding ratio based on the screen content layout. The vehicle projection device will project the second projection image of the above-mentioned screen content layout onto the vehicle screen at the second unfolding ratio.

[0071] If the projection adjustment command is for the vehicle screen, indicating that the unfolding ratio of the vehicle screen needs to be adjusted, then after the unfolding ratio of the vehicle target is adjusted by voice or controller, a second unfolding ratio can be obtained. The terminal can then determine the screen layout content that the target application can adapt to based on the second unfolding ratio, and form a second projection image to send to the vehicle projection device. The vehicle projection device can then project the second projection image onto the vehicle screen with the second unfolding ratio.

[0072] In the aforementioned vehicle projection control method, a first projection image of the target application, with a screen content layout adapted to a first unfolding ratio, is projected onto a vehicle screen with a first unfolding ratio using a vehicle projection device. In response to a projection adjustment command triggered by the target application or the controller, a second projection image of the target application, adapted to a second unfolding ratio, is projected onto a vehicle screen with a second unfolding ratio. Compared to traditional projection using a screen unfolded to a fixed size, this solution allows for stepless screen adjustment or application adjustment upon activation, ensuring that the screen content layout adapts to the screen's unfolding ratio without interrupting application use, thus improving the compatibility between the vehicle projection screen and the application.

[0073] In one embodiment, in response to a projection adjustment command, the method further includes projecting a second projection image of a target application onto a vehicle screen with a second unfolding ratio in front of the target application.

[0074] In this embodiment, the aforementioned projection adjustment command can be a projection adjustment command triggered in the target application. For example, it can be an adjustment command in the target application to change the layout of the screen content. This command can be obtained by selecting from multiple preset screen content layouts in the target application, thereby forming the selected screen content layout and generating the projection adjustment command. Thus, the vehicle-mounted projection device can obtain the projection adjustment command triggered in the target application and project the corresponding second projection screen.

[0075] In one embodiment, in response to a projection adjustment command, projecting a second projection image of a target application onto a vehicle screen with a second unfolding ratio includes: in response to a projection adjustment command, acquiring a second projection image provided by the target application, controlling the vehicle screen to unfold to a second unfolding ratio, and projecting the second projection image onto the vehicle screen with the second unfolding ratio.

[0076] In this embodiment, the aforementioned projection adjustment command can be a projection adjustment command triggered by the target application. After the projection adjustment command is triggered by the target application, the terminal can determine the adjusted screen content layout of the target application based on the projection adjustment command, forming a corresponding second projection screen. The terminal sends the second projection screen of the target application to the in-vehicle projection device, thereby the in-vehicle projection device responds to the projection adjustment command and obtains the second projection screen provided by the target application. The projection adjustment command triggered by the target application can be a command to adjust the screen content layout of the current application, or it can be a command to open a new target application.

[0077] The in-vehicle projection device can control the in-vehicle screen to unfold to a second unfolding ratio based on the second projection image provided by the target application, so that the layout of the in-vehicle screen matches the content of the second projection image at the second unfolding ratio. Thus, the in-vehicle projection device can project the aforementioned second projection image onto the in-vehicle screen at the second unfolding ratio. Specifically, the in-vehicle projection device can instruct the controller to adjust the in-vehicle screen to the aforementioned second unfolding ratio by sending an adjustment signal to the controller.

[0078] Through the above embodiments, the vehicle-mounted projection device can receive projection adjustment instructions initiated from the target application, and based on the projection adjustment instructions, receive the second projection image sent from the target application, control the vehicle screen to adjust to the second unfolding ratio, so that the second projection image is adapted to the second unfolding ratio, thereby improving the adaptability of the vehicle-mounted projection.

[0079] In one embodiment, before projecting the second projection image of the target application onto a vehicle screen with a second unfolding ratio in response to a projection adjustment command, the method further includes: obtaining a projection adjustment command based on a screen control command for controlling the unfolding ratio of the vehicle screen; the screen control command is used to instruct the vehicle screen to unfold to the second unfolding ratio.

[0080] In this embodiment, the aforementioned projection adjustment command can also be obtained based on the screen control command for the vehicle-mounted screen. The screen control command can be used to control the unfolding ratio of the vehicle-mounted screen. The screen control command can be initiated through a controller or through voice commands, etc. The vehicle-mounted projection device can obtain the screen control command and obtain the corresponding projection adjustment command based on it. For example, if the vehicle-mounted projection device determines that the screen needs to be adjusted to a second unfolding ratio based on the screen control command, then the first projected image needs to be adjusted to fit the vehicle-mounted screen at the second unfolding ratio. The vehicle-mounted projection device can generate the projection adjustment command based on the screen control command and then respond to the projection adjustment command.

[0081] In one embodiment, in response to a projection adjustment command, projecting a second projection image of a target application onto a vehicle screen with a second unfolding ratio includes: in response to a projection adjustment command, requesting a second projection image from the target application and projecting the second projection image onto a vehicle screen with a second unfolding ratio.

[0082] In this embodiment, the aforementioned vehicle-mounted screen can be in a first unfolding ratio. After a projection adjustment command for the unfolding ratio of the vehicle-mounted screen is triggered, the vehicle-mounted projection device can respond to the projection adjustment command and request a second projection image from the target application. That is, it requests a second projection image whose content layout is adapted to the second unfolding ratio from the target application in the terminal. If the request is successful, the vehicle-mounted projection device projects the second projection image onto the vehicle-mounted screen in the second unfolding ratio. During the process of requesting the second projection image from the target application, the vehicle-mounted projection device can continue to use the target application and the projection process without interrupting the use of the target application.

[0083] Through the above embodiments, the vehicle-mounted projection device can respond to the screen control command to generate a projection adjustment command, and request a second projection image from the target application based on the projection adjustment command, so that the second projection image is adapted to the second unfolding ratio, thereby improving the adaptability of the vehicle-mounted projection.

[0084] In one exemplary embodiment, such as Figure 4 As shown, a vehicle-mounted projection control method is provided, which is applied to... Figure 1 Taking the terminal in the example, the explanation includes the following steps S402 to S404. Wherein:

[0085] Step S402: The first projection image of the target application is transmitted to the vehicle projection device so that the vehicle projection device can project the first projection image onto the vehicle screen with the first unfolding ratio; the layout of the image content of the first projection image is adapted to the first unfolding ratio.

[0086] The terminal can be an integrated vehicle control terminal or a standalone terminal. Multiple applications can be installed on the terminal. The application requiring projection can be referred to as the target application. The terminal can create a screen content layout based on the target application's interface and the first unfolding ratio of the vehicle screen, and then create a first projected image based on the same layout, ensuring the content layout of the first projected image is adapted to the first unfolding ratio. The terminal can transmit this first projected image to an in-vehicle projection device, which can then project the first projected image onto the vehicle screen at the first unfolding ratio.

[0087] In step S404, in response to the projection adjustment command, the second projection image of the target application is transmitted to the vehicle projection device so that the vehicle projection device can project the second projection image onto the vehicle screen with the second unfolding ratio; the layout of the image content of the second projection image is adapted to the second unfolding ratio; the first unfolding ratio is different from the second unfolding ratio.

[0088] The projection adjustment command can be an instruction to change the projected image. Specifically, it can be issued to adjust a target application on the terminal or a vehicle-mounted screen. In response to this projection adjustment command, the terminal, the vehicle-mounted projection device, and the controller can make corresponding adjustments based on different commands, thus re-adapting the unfolding ratio of the vehicle-mounted screen to the layout of the target application's image content. For example, if the first projection image of the target application is projected onto a vehicle-mounted screen with a first unfolding ratio, the terminal, in response to the projection adjustment command, can transmit the second projection image of the target application to the vehicle-mounted projection device, allowing the device to project the second image onto a vehicle-mounted screen with a second unfolding ratio. The layout of the second projection image can be adapted to a second unfolding ratio, and the first and second unfolding ratios are different.

[0089] If the projection adjustment command is an adjustment command for a target application, indicating that the new target application needs to be projected onto the vehicle screen, the terminal can determine the screen content layout of the target application, generate the corresponding second projection screen, and transmit it to the vehicle projection device. The vehicle projection device can control the vehicle screen to rise and fall from the first unfolding ratio to the second unfolding ratio based on the screen content layout. The vehicle projection device projects the second projection screen with the above-mentioned screen content layout onto the vehicle screen with the second unfolding ratio.

[0090] If the projection adjustment command is for the vehicle screen, indicating that the unfolding ratio of the vehicle screen needs to be adjusted, then after the unfolding ratio of the vehicle target is adjusted by voice or controller, a second unfolding ratio can be obtained. The terminal can then determine the screen layout content that the target application can adapt to based on the second unfolding ratio, and form a second projection image to send to the vehicle projection device. The vehicle projection device can then project the second projection image onto the vehicle screen with the second unfolding ratio.

[0091] In the aforementioned vehicle projection control method, a first projection image of the target application, with a screen content layout adapted to a first unfolding ratio, is projected onto a vehicle screen with a first unfolding ratio using a vehicle projection device. In response to a projection adjustment command triggered by the target application or the controller, a second projection image of the target application, adapted to a second unfolding ratio, is projected onto a vehicle screen with a second unfolding ratio. Compared to traditional projection using a screen unfolded to a fixed size, this solution allows for stepless screen adjustment or application adjustment upon activation, ensuring that the screen content layout adapts to the screen's unfolding ratio without interrupting application use, thus improving the compatibility between the vehicle projection screen and the application.

[0092] In one embodiment, before transmitting the second projected image of the target application to the vehicle-mounted projection device in response to a projection adjustment command, the method further includes: acquiring a projection adjustment command triggered in the target application.

[0093] In this embodiment, the aforementioned projection adjustment command can be a projection adjustment command triggered in the target application. For example, it can be an adjustment command that changes the screen content layout of the target application, including changing the screen content layout of the current target application or opening a new target application. For commands that change the screen content layout of the current target application, selection can be made from a set of multiple preset screen content layouts within the target application. The terminal can then obtain the selected screen content layout and form a projection adjustment command. Thus, the terminal can obtain the projection adjustment command triggered in the target application, send the second projection image to the in-vehicle projection device, and project the corresponding second projection image.

[0094] For example, based on a projection adjustment command, the terminal can determine the adjusted layout of the target application's screen content, forming a corresponding second projected image. The terminal then sends this second projected image to the in-vehicle projection device. The in-vehicle projection device, responding to the projection adjustment command, acquires the second projected image provided by the target application. Based on this second projected image, the in-vehicle projection device can control the in-vehicle screen to expand to a second expansion ratio, ensuring that the screen's layout matches the second projected image's content layout. Thus, the in-vehicle projection device can project this second projected image onto the in-vehicle screen at the second expansion ratio.

[0095] In this embodiment, the terminal can send a second projection image to the vehicle projection device based on the projection adjustment command initiated by the target application. The vehicle projection device controls the vehicle screen to adjust to the second unfolding ratio based on the second projection image, so that the second projection image is adapted to the second unfolding ratio, thereby improving the adaptability of the vehicle projection.

[0096] In one embodiment, in response to a projection adjustment command, transmitting a second projected image of a target application to an in-vehicle projection device includes: in response to the projection adjustment command, obtaining an image request from the in-vehicle projection device; and transmitting the second projected image of the target application to the in-vehicle projection device according to the image request.

[0097] In this embodiment, the projection adjustment command can also be obtained based on the screen control command for the vehicle-mounted screen. The screen control command can be used to control the unfolding ratio of the vehicle-mounted screen. The screen control command can be initiated through a controller or through voice commands, etc. The vehicle-mounted projection device can obtain the screen control command and obtain the corresponding projection adjustment command based on it. Thus, the terminal can respond to the projection adjustment command.

[0098] For example, the in-vehicle projection device requests a second projection image from the target application, that is, it requests a second projection image with a content layout adapted to a second unfolding ratio from the target application on the terminal. The terminal can respond to the projection adjustment command, receive the image request from the in-vehicle projection device, and then determine the second projection image with a content layout that meets the second unfolding ratio for the target application based on the image request, and transmit the second projection image to the in-vehicle projection device. After receiving the second projection image, the in-vehicle projection device projects the second projection image onto the in-vehicle screen with the second unfolding ratio. During the process of requesting the second projection image from the target application, the use of the target application and the projection process can be uninterrupted.

[0099] In this embodiment, the vehicle-mounted projection device can respond to the screen control command to generate a projection adjustment command, and request a second projection screen from the target application in the terminal based on the projection adjustment command. The terminal determines the second projection screen with the screen content layout adapted based on the second unfolding ratio, so that the second projection screen is adapted to the second unfolding ratio, thereby improving the adaptability of the vehicle-mounted projection.

[0100] In one embodiment, the method further includes: obtaining a target screen content layout corresponding to the target unfolding ratio from a set of screen content layouts based on the target unfolding ratio of the vehicle screen; obtaining a target projection screen based on the target screen content layout; the target unfolding ratio includes a first unfolding ratio or a second unfolding ratio, and the target projection screen includes a first projection screen or a second projection screen.

[0101] In this embodiment, the projection adjustment command can be obtained based on the screen control command. The controller adjusts the vehicle screen to the corresponding unfolding ratio based on the screen control command, and the terminal can obtain the target unfolding ratio of the vehicle screen based on the projection adjustment command. The terminal stores a set of screen content layouts corresponding to the target application. This set of screen content layouts pre-stores screen content layouts adapted to different unfolding ratios for the target application. The terminal can then obtain the content layout of the target screen content corresponding to the target unfolding ratio from the set of screen content layouts. The terminal can obtain the target projected image based on the target screen content layout. The target unfolding ratio includes a first unfolding ratio or a second unfolding ratio, and the target projected image includes a first projected image or a second projected image. The terminal can adjust the position and size of various contents in the target application to form a set of screen content layouts containing different screen content layouts, and then the terminal can determine the target screen content layout adapted to the target unfolding ratio.

[0102] In one embodiment, before obtaining the target screen content layout corresponding to the target unfolding ratio from the screen content layout set according to the target unfolding ratio of the vehicle screen, the method further includes: for non-fully unfolded ratios, determining the content projection range and non-content projection range corresponding to the vehicle screen; obtaining the effective content layout corresponding to the content projection range based on the projection layout of the application content of the target application within the content projection range; obtaining the screen content layout based on the preset content layout acting on the non-content projection range and the effective content layout; and obtaining the screen content layout set based on the screen content layout corresponding to each unfolding ratio.

[0103] In this embodiment, the terminal can pre-generate a set of screen content layouts. Among them, the incomplete unfolding ratio represents the ratio corresponding to when the vehicle screen is not fully unfolded. At this time, the screen size of the vehicle screen is not a regular screen size. Therefore, the terminal needs to adapt the screen content layout for each incomplete unfolding ratio so that the image of the terminal's target application projected onto the vehicle screen is still adapted even when the vehicle screen is in an incomplete unfolding ratio.

[0104] For example, for a partially expanded screen ratio, the terminal can determine the content projection range and non-content projection range corresponding to the in-vehicle screen. The content projection range represents the area on the in-vehicle screen where image content is projected, while the non-content projection range represents the area on the in-vehicle screen where no image content is projected. Different partially expanded screen ratios have different content projection ranges and non-content projection ranges. The terminal can obtain the effective content layout corresponding to the content projection range based on the projection layout of the target application's content within the content projection range. Here, application content refers to the various elements in the target application's application interface, and the terminal can adjust the projection layout of the application content to form the projection layout within each content projection range.

[0105] The terminal can obtain the screen content layout based on the preset content layout and the effective content layout applied to the non-content projection area. The terminal can generate different screen content layouts for different incomplete expansion ratios. Therefore, the terminal can obtain a set of screen content layouts based on the screen content layouts corresponding to each expansion ratio. Thus, the terminal can use this set of screen content layouts to adjust the projected image.

[0106] Specifically, such as Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the change in screen content layout in one embodiment. Taking a 50% raised / lowered vehicle screen as an example, 50% screen unfolding indicates a non-fully unfolded ratio. At this time, the terminal can determine the target screen content layout from the set of screen content layouts that satisfies the 50% unfolding ratio of the vehicle screen, such as... Figure 5 The system adjusts the position and size of lyrics and characters to create an effective content layout that fits the projection area. For areas outside the projection area, the terminal can control the image to be black, ensuring that when the in-vehicle projector projects the above image, the content layout portion is projected normally, while the non-content layout portion remains unlit. In this case, the actual projected pixel count of the in-vehicle projector remains 100%. For example, with a maximum in-vehicle screen size of 1920*1080, and adjusting the screen from 100% to 50% unfolded, the projected image size can change from 1920*1080 to 1920*540. By controlling the color of the non-content portion to black (which is unlit during projection), the content layout and unfolded ratio are adapted.

[0107] Through the above embodiments, the terminal can generate a set of screen content layouts corresponding to the target application in advance based on the unfolding ratio of the vehicle screen and the content projection part and the non-content projection part. Thus, when the vehicle screen is not fully unfolded, the terminal can determine the projection screen corresponding to the target screen content layout that meets the unfolding ratio of the vehicle screen based on the set of screen content layouts, thereby improving the adaptability of projection in the vehicle.

[0108] In one exemplary embodiment, such as Figure 6 As shown, a vehicle-mounted projection control method is provided, which is applied to... Figure 1 Taking the controller in the example, the explanation includes the following steps S602 to S604. Wherein:

[0109] Step S602: Control the vehicle screen to unfold to a first unfolding ratio; the vehicle screen at the first unfolding ratio is used to project the first projection image of the target application; the layout of the content of the first projection image is adapted to the first unfolding ratio.

[0110] The vehicle-mounted screen can be controlled via a controller or voice commands. For example, the controller can unfold the screen to a first unfolding ratio. This first unfolding ratio can be either fully unfolded or partially unfolded. At the first unfolding ratio, the screen can be used to project a first image of the target application, and the layout of the first projected image is adapted to the first unfolding ratio.

[0111] Step S604: In response to the projection adjustment command, control the vehicle screen to unfold to the second unfolding ratio; the vehicle screen at the second unfolding ratio is used to project the second projection image of the target application; the layout of the image content of the second projection image is adapted to the second unfolding ratio; the first unfolding ratio is different from the second unfolding ratio.

[0112] The projection adjustment command can include commands to adjust the unfolding ratio of the vehicle screen, or commands to select a target application. The controller can respond to the projection adjustment command and control the vehicle screen to unfold to a second unfolding ratio. In the second unfolding ratio, the layout of the second projected image is adapted to the second unfolding ratio, and the first and second unfolding ratios are different.

[0113] If the projection adjustment command is initiated by the controller, the controller will respond to the projection adjustment command by obtaining a screen control command. This screen control command can be a command to actively control the unfolding ratio of the vehicle screen. The controller can control the vehicle screen to unfold to a second unfolding ratio according to the screen control command.

[0114] If the projection adjustment command is initiated through the target application in the terminal, the controller responds to the projection adjustment command and can obtain the screen control command for the vehicle projection device. This screen control command can be a command for adapting the screen content layout of the second projection screen to the target application. The controller can then control the vehicle screen to unfold to a second unfolding ratio based on the screen control command.

[0115] In the aforementioned vehicle projection control method, a first projection image of the target application, with a screen content layout adapted to a first unfolding ratio, is projected onto a vehicle screen with a first unfolding ratio using a vehicle projection device. In response to a projection adjustment command triggered by the target application or the controller, a second projection image of the target application, adapted to a second unfolding ratio, is projected onto a vehicle screen with a second unfolding ratio. Compared to traditional projection using a screen unfolded to a fixed size, this solution allows for stepless screen adjustment or application adjustment upon activation, ensuring that the screen content layout adapts to the screen's unfolding ratio without interrupting application use, thus improving the compatibility between the vehicle projection screen and the application.

[0116] In one exemplary embodiment, such as Figure 7 As shown, Figure 7 This is a flowchart illustrating the vehicle projection control method in another embodiment. In this embodiment, the projection adjustment commands include projection adjustment commands for the target application and adjustment commands for the vehicle screen. For projection adjustment commands triggered by the target application, since the screen height is adjustable, the terminal can design an adaptive application interface. By selecting an application function, the screen height can be adjusted accordingly. For example, the vehicle screen is first fully extended (100% extended). The terminal detects the target application selection command and determines whether the target application is a full-screen application. If so, the terminal sends the projection image of the target application to the vehicle projection device to project the content of the target application. If the target application is not a full-screen application, the terminal sends the projection image of the target application, including both the content portion and the non-content portion, to the vehicle projection device. The vehicle projection device controls the vehicle screen to adjust to a suitable height, i.e., a suitable extension ratio, based on this projection image. For example, the vehicle screen is raised by 50%, so that the extension ratio of the vehicle screen adapts to the projection image of the target application.

[0117] For projection adjustment commands triggered by the in-vehicle screen, the application's adaptive interface can be automatically displayed by controlling the screen's height. For example, the in-vehicle screen is first fully extended (100%). If the controller detects a screen control command, such as raising the screen by 50%, the target application being displayed needs to adjust its content layout to fit the adjusted screen's extension ratio. The controller sends the adjustment information to the in-vehicle projection device, which requests a second projection image of the target application from the terminal. The terminal checks if the target application has an adaptive interface, for example, by selecting from a set of content layouts. If no content layout matches the screen's current extension ratio, the in-vehicle projection device continues to project the target application according to its current layout. If a content layout matches the screen's current extension ratio, the terminal sends a second projection image with the appropriate extension ratio to the in-vehicle projection device, which projects the second image onto the adjusted screen without interrupting application usage.

[0118] Through the above embodiments, when adjusting the screen using stepless adjustment or application activation, the layout of the screen content adapts to the screen's unfolding ratio without interrupting application use, improving the compatibility between the in-vehicle projection screen and the application. Furthermore, when adjusting the screen height, the adaptive interface application does not interrupt application use; the application and screen work well together, whereas full-screen applications will either cease use or fail to provide a satisfactory experience. Additionally, the non-full-screen projection shows the scene in front of the vehicle, giving users a sense of spaciousness. The non-full-screen projection also leaves space for communication between front and rear passengers and allows for the passing of items, improving the utilization of interior space.

[0119] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
