[0061] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] The vehicle projection control method provided by the embodiment of the present application can be applied to the application environment shown in Figure 1. Among them, the controller of the vehicle screen, the vehicle projection device and the terminal can communicate with each other. When the controller performs a lifting operation on the vehicle screen, or the terminal adjusts the application of the 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 expansion ratio of the vehicle screen onto the vehicle screen based on the application information sent by the controller of the vehicle screen or the terminal.

[0063] In an exemplary embodiment, as shown in FIG2 , a vehicle-mounted projection control method is provided, which is described by taking the method applied to the vehicle-mounted projection device in FIG1 as an example, and includes the following steps S202 to S204. Among them:

[0064] Step S202: projecting a first projection screen of the target application onto a vehicle-mounted screen of a first expansion ratio; the screen content layout of the first projection screen is adapted to the first expansion ratio.

[0065] Among them, a vehicle-mounted screen and a vehicle-mounted projection device may be provided in the vehicle. Among them, the vehicle-mounted projection device may use laser projection technology to project the image onto the vehicle-mounted screen. The vehicle-mounted screen supports electric lifting and storage, and can realize stepless height adjustment or customized fixed multiple gears to meet various display needs. Among them, the setting method of the vehicle-mounted screen and the vehicle projection device may be as shown in Figure 3, which is a structural schematic diagram of the interior of the vehicle in one embodiment. The vehicle-mounted screen may be set on the roof between the front and rear rows of the vehicle, and the vehicle projection device may be set on the roof behind the rear row of the vehicle or other positions in the vehicle that can be projected onto the vehicle-mounted screen. Thereby, the rear passengers can sit in the back row and watch the image projected by the vehicle-mounted projection device on the vehicle-mounted screen.

[0066] Among them, the lifting and lowering of the vehicle-mounted screen can be controlled by a controller, or by signals such as voice commands. The target application can be an application in the terminal that needs to be projected, wherein the terminal can be an independent mobile terminal or a vehicle-mounted terminal integrated in the vehicle. The vehicle-mounted projection device can project the projection screen of the target application in the terminal. For example, the vehicle-mounted projection device can project the first projection screen of the above-mentioned target application onto the vehicle-mounted screen of the first expansion ratio. Among them, the vehicle-mounted projection device can only project the projection screen after the vehicle-mounted screen needs to be unfolded. The expansion ratio of the vehicle-mounted screen can be determined based on the screen content layout of the target application, and the screen content layout of the target application can also be adaptively adjusted based on the expansion ratio of the vehicle-mounted screen. The screen content layout of the above-mentioned first projection screen is adapted to the first expansion ratio.

[0067] Among them, the screen content layout can be the layout of each content in the screen presented when the target application is projected onto the vehicle screen. The screen content layout can be adjusted according to the expansion ratio of the vehicle screen, and the expansion 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 instruction, projecting the second projection screen of the target application onto the vehicle-mounted screen of the second expansion ratio; the screen content layout of the second projection screen is adapted to the second expansion ratio; the first expansion ratio is different from the second expansion ratio.

[0069] Among them, the projection adjustment instruction can be an instruction to change the projected picture. Among them, the projection adjustment instruction can be issued for adjusting the target application in the terminal or the vehicle-mounted screen. In response to the projection adjustment instruction, the terminal, the vehicle-mounted projection device and the controller can make corresponding adjustments based on different projection adjustment instructions, so that the expansion ratio of the vehicle-mounted screen and the screen content layout of the target application are adapted again. For example, the first projection picture of the above-mentioned target application is projected onto the vehicle-mounted screen with a first expansion ratio, and the vehicle-mounted projection device responds to the projection adjustment instruction to project the second projection picture of the target application onto the vehicle-mounted screen with a second expansion ratio. Among them, the picture content layout of the above-mentioned second projection picture can be adapted to the second expansion ratio, and the first expansion ratio and the second expansion ratio are different.

[0070] Among them, if the projection adjustment instruction is an adjustment instruction for the target application, indicating that the new target application needs to be projected onto the vehicle-mounted screen, the terminal can determine the screen content layout of the target application, and the vehicle-mounted projection device can control the vehicle-mounted screen from the first expansion ratio to the second expansion ratio based on the screen content layout. The vehicle-mounted projection device projects the second projection screen of the above screen content layout onto the vehicle-mounted screen with the second expansion ratio.

[0071] If the projection adjustment instruction is an adjustment instruction for the vehicle-mounted screen, indicating that the expansion ratio of the vehicle-mounted screen needs to be adjusted, then after the expansion ratio of the vehicle-mounted target is adjusted through voice or controller, a second expansion ratio can be obtained. The terminal can determine the screen layout content that the target application can adapt to based on the second expansion ratio, and form a second projection picture and send it to the vehicle-mounted projection device. The vehicle-mounted projection device can project the above-mentioned second projection picture onto the vehicle-mounted screen with the second expansion ratio.

[0072] In the above-mentioned vehicle projection control method, the first projection screen of the target application that is adapted to the first expansion ratio of the screen content layout is projected to the vehicle screen of the first expansion ratio through the vehicle projection device, and in response to the projection adjustment instruction triggered in the target application or triggered by the controller, the second projection screen of the target application that is adapted to the second expansion ratio is projected to the vehicle screen of the second expansion ratio. Compared with the traditional projection of the screen with a fixed size, this solution makes the screen content layout adapt to the expansion ratio of the screen without interrupting the use of the application through the infinite adjustment of the screen or the adjustment of the awakened application, thereby improving the adaptability between the screen and the application of the vehicle projection.

[0073] In one embodiment, in response to the projection adjustment instruction, before projecting the second projection picture of the target application onto the vehicle-mounted screen of the second expansion ratio, the method further includes: obtaining the projection adjustment instruction triggered in the target application.

[0074] In this embodiment, the projection adjustment instruction may be a projection adjustment instruction triggered in the target application, for example, an adjustment instruction for the target application to change the screen content layout, and the instruction may be selected from a plurality of preset screen content layout sets in the target application, and then the selected screen content layout is obtained to form a projection adjustment instruction. Thus, the vehicle-mounted projection device may obtain the projection adjustment instruction triggered in the target application, and perform the projection of the corresponding second projection screen.

[0075] In one embodiment, in response to a projection adjustment instruction, a second projection picture of the target application is projected onto a vehicle-mounted screen with a second expansion ratio, including: in response to the projection adjustment instruction, obtaining a second projection picture provided by the target application, controlling the vehicle-mounted screen to expand to the second expansion ratio, and projecting the second projection picture onto the vehicle-mounted screen with the second expansion ratio.

[0076] In this embodiment, the projection adjustment instruction may be a projection adjustment instruction triggered by the target application. After the projection adjustment instruction is triggered in the target application, the terminal may determine the adjusted screen content layout of the target application based on the projection adjustment instruction to form a corresponding second projection screen. The terminal sends the second projection screen of the target application to the vehicle-mounted projection device, so that the vehicle-mounted projection device responds to the projection adjustment instruction and obtains the second projection screen provided by the target application. The projection adjustment instruction triggered in the target application may be an instruction for adjusting the screen content layout of the current application, or an adjustment instruction for opening a new target application.

[0077] The vehicle-mounted projection device can control the vehicle-mounted screen to expand to the second expansion ratio based on the second projection picture provided by the target application, so that the vehicle-mounted screen is adapted to the layout of the picture content of the second projection picture when the vehicle-mounted screen is at the second expansion ratio. Thus, the vehicle-mounted projection device can project the above-mentioned second projection picture onto the vehicle-mounted screen of the second expansion ratio. Among them, the vehicle-mounted projection device can instruct the controller to adjust the vehicle-mounted screen to the above-mentioned second expansion ratio by sending an adjustment signal to the controller.

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

[0079] In one embodiment, in response to a projection adjustment instruction, before projecting a second projection picture of the target application onto a vehicle-mounted screen with a second expansion ratio, the method also includes: obtaining a projection adjustment instruction according to a screen control instruction for controlling the expansion ratio of the vehicle-mounted screen; the screen control instruction is used to instruct the vehicle-mounted screen to expand to the second expansion ratio.

[0080] In this embodiment, the above-mentioned projection adjustment instruction can also be obtained based on the screen control instruction for the above-mentioned vehicle-mounted screen. Among them, the screen control instruction can be used to control the expansion ratio of the vehicle-mounted screen. The screen control instruction can be initiated by a controller, or by voice instructions and the like. The vehicle-mounted projection device can obtain the screen control instruction, and obtain the corresponding projection adjustment instruction based on the screen control instruction. For example, the vehicle-mounted projection device determines that the screen needs to be adjusted to a second expansion ratio based on the screen control instruction. At this time, the projected first projection picture needs to be adjusted to adapt to the vehicle-mounted screen of the second expansion ratio. The vehicle-mounted projection device can generate a projection adjustment instruction based on the screen control instruction, and then respond to the projection adjustment instruction.

[0081] In one embodiment, in response to a projection adjustment instruction, projecting a second projection screen of the target application onto a vehicle-mounted screen of a second expansion ratio includes: in response to the projection adjustment instruction, requesting the second projection screen from the target application, and projecting the second projection screen onto the vehicle-mounted screen of a second expansion ratio.

[0082] In this embodiment, the vehicle-mounted screen may be at the first unfolding ratio. After the projection adjustment instruction for the unfolding ratio of the vehicle-mounted screen is triggered, the vehicle-mounted projection device may respond to the projection adjustment instruction and request the target application for the second projection screen, that is, request the target application in the terminal to adapt the screen content layout to the second projection screen of the second unfolding ratio. If the request is successful, the vehicle-mounted projection device projects the second projection screen to the vehicle-mounted screen of the second unfolding ratio. In particular, the vehicle-mounted projection device may not interrupt the use and projection process of the target application during the request for the second projection screen from the target application.

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

[0084] In an exemplary embodiment, as shown in FIG4 , a vehicle-mounted projection control method is provided, which is described by taking the method applied to the terminal in FIG1 as an example, and includes the following steps S402 to S404. Among them:

[0085] Step S402, transmitting a first projection picture of the target application to the vehicle-mounted projection device, so that the vehicle-mounted projection device projects the first projection picture onto a vehicle-mounted screen of a first expansion ratio; the picture content layout of the first projection picture is adapted to the first expansion ratio.

[0086] Among them, the terminal can be a vehicle control terminal integrated in the vehicle, or it can be an independently set terminal. Multiple applications can be installed in the terminal. Among them, the one that needs to be projected can be called the target application. The terminal can form a screen content layout based on the application interface of the target application and the first expansion ratio of the vehicle-mounted screen, and form a first projection screen based on the screen content layout and the first expansion ratio of the vehicle-mounted screen, so that the screen content layout of the first projection screen is adapted to the first expansion ratio. The terminal can transmit the above-mentioned first projection screen to the vehicle-mounted projection device, so that the vehicle-mounted projection device can project the first projection screen onto the vehicle-mounted screen of the first expansion ratio.

[0087] Step S404, in response to the projection adjustment instruction, transmit the second projection picture of the target application to the vehicle-mounted projection device, so that the vehicle-mounted projection device projects the second projection picture onto the vehicle-mounted screen of the second expansion ratio; the picture content layout of the second projection picture is adapted to the second expansion ratio; the first expansion ratio is different from the second expansion ratio.

[0088] Among them, the projection adjustment instruction can be an instruction to change the projected picture. Among them, the projection adjustment instruction can be issued for adjusting the target application in the terminal or the vehicle-mounted screen. In response to the projection adjustment instruction, the terminal, the vehicle-mounted projection device and the controller can make corresponding adjustments based on different projection adjustment instructions, so that the expansion ratio of the vehicle-mounted screen and the screen content layout of the target application are adapted again. For example, the first projection picture of the above-mentioned target application is projected to the vehicle-mounted screen of the first expansion ratio. In response to the projection adjustment instruction, the terminal can transmit the second projection picture of the target application to the vehicle-mounted projection device, so that the vehicle-mounted projection device projects the second projection picture to the vehicle-mounted screen of the second expansion ratio. Among them, the picture content layout of the above-mentioned second projection picture can be adapted to the second expansion ratio, and the first expansion ratio and the second expansion ratio are different.

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

[0090] If the projection adjustment instruction is an adjustment instruction for the vehicle-mounted screen, indicating that the expansion ratio of the vehicle-mounted screen needs to be adjusted, then after the expansion ratio of the vehicle-mounted target is adjusted through voice or controller, a second expansion ratio can be obtained. The terminal can determine the screen layout content that the target application can adapt to based on the second expansion ratio, and form a second projection picture and send it to the vehicle-mounted projection device. The vehicle-mounted projection device can project the above-mentioned second projection picture onto the vehicle-mounted screen with the second expansion ratio.

[0091] In the above-mentioned vehicle projection control method, the first projection screen of the target application that is adapted to the first expansion ratio of the screen content layout is projected to the vehicle screen of the first expansion ratio through the vehicle projection device, and in response to the projection adjustment instruction triggered in the target application or triggered by the controller, the second projection screen of the target application that is adapted to the second expansion ratio is projected to the vehicle screen of the second expansion ratio. Compared with the traditional projection of the screen with a fixed size, this solution makes the screen content layout adapt to the expansion ratio of the screen without interrupting the use of the application through the infinite adjustment of the screen or the adjustment of the awakened application, thereby improving the adaptability between the screen and the application of the vehicle projection.

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

[0093] In this embodiment, the projection adjustment instruction may be a projection adjustment instruction triggered in the target application, for example, an adjustment instruction for the target application to change the screen content layout, including changing the screen content layout of the current target application, or opening a new target application, etc. For the instruction to change the screen content layout of the current target application, a selection may be made from a plurality of preset screen content layout sets in the target application, and then the terminal may obtain the selected screen content layout to form a projection adjustment instruction. Thus, the terminal may obtain the projection adjustment instruction triggered in the target application, send the second projection screen to the vehicle-mounted projection device, and perform the corresponding projection of the second projection screen.

[0094] For example, based on the projection adjustment instruction, the terminal can determine the layout of the screen content after the target application is adjusted to form a corresponding second projection screen. The terminal sends the second projection screen of the target application to the vehicle-mounted projection device, so that the vehicle-mounted projection device responds to the projection adjustment instruction and obtains the second projection screen provided by the target application. The vehicle-mounted projection device can control the vehicle-mounted screen to expand to a second expansion ratio based on the second projection screen provided by the target application, so that the vehicle-mounted screen is adapted to the screen content layout of the second projection screen when the vehicle-mounted screen is at the second expansion ratio. Thus, the vehicle-mounted projection device can project the above-mentioned second projection screen onto the vehicle-mounted screen of the second expansion ratio.

[0095] Through this embodiment, the terminal can send a second projection picture to the vehicle-mounted projection device based on the projection adjustment instruction initiated in the target application. The vehicle-mounted projection device controls the vehicle-mounted screen to adjust to the second expansion ratio based on the second projection picture, so that the second projection picture is adapted to the second expansion ratio, thereby improving the adaptability of the vehicle-mounted projection.

[0096] In one embodiment, in response to a projection adjustment instruction, a second projection picture of the target application is transmitted to a vehicle-mounted projection device, including: in response to the projection adjustment instruction, obtaining a picture request of the vehicle-mounted projection device; and transmitting the second projection picture of the target application to the vehicle-mounted projection device according to the picture request.

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

[0098] For example, the vehicle-mounted projection device requests the target application for a second projection screen, that is, requests the target application in the terminal to adapt the screen content layout to the second projection screen of the second expansion ratio. The terminal can respond to the projection adjustment instruction and obtain the screen request of the vehicle-mounted projection device, so that the terminal can determine the second projection screen of the target application that meets the screen content layout of the second expansion ratio according to the above screen request, and transmit the second screen to the vehicle-mounted projection device. Therefore, after requesting the second projection screen, the vehicle-mounted projection device projects the second projection screen to the vehicle-mounted screen of the second expansion ratio. Among them, the vehicle-mounted projection device can not interrupt the use and projection process of the target application during the request for the second projection screen from the target application.

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

[0100] In one embodiment, the method also includes: according to the target expansion ratio of the vehicle-mounted screen, obtaining the target screen content layout corresponding to the target expansion ratio from the screen content layout set; according to the target screen content layout, obtaining the target projection screen; the target expansion ratio includes the first expansion ratio or the second expansion ratio, and the target projection screen includes the first projection screen or the second projection screen.

[0101] In this embodiment, the above-mentioned projection adjustment instruction can be obtained based on the screen control instruction, and the controller adjusts the vehicle-mounted screen to the corresponding expansion ratio based on the screen control instruction, and the terminal can obtain the target expansion ratio of the vehicle-mounted screen based on the projection adjustment instruction. Among them, the terminal stores a screen content layout set corresponding to the target application. The screen content layout set pre-stores the screen content layout adapted to different expansion ratios corresponding to the target application. Then the terminal can obtain the content layout of the target screen content corresponding to the target expansion ratio from the screen content layout set according to the above-mentioned target expansion ratio. The terminal can obtain the target projection screen according to the above-mentioned target screen content layout. Among them, the target expansion ratio includes a first expansion ratio or a second expansion ratio, and the target projection screen includes a first projection screen or a second projection screen. The terminal can adjust the position and size of each content in the target application to form a screen content layout set containing different screen content layouts, and then the terminal can determine the target screen content layout adapted to the target expansion ratio based on the target expansion ratio.

[0102] In one embodiment, according to the target expansion ratio of the vehicle-mounted screen, before obtaining the target screen content layout corresponding to the target expansion ratio from the screen content layout set, it also includes: determining the content projection range and non-content projection range corresponding to the vehicle-mounted screen for the non-complete expansion ratio; obtaining the effective content layout corresponding to the content projection range according to the projection layout of the application content of the target application in the content projection range; obtaining the screen content layout according to the preset content layout and the effective content layout acting on the non-content projection range; and obtaining the screen content layout set according to the screen content layout corresponding to each expansion ratio.

[0103] In this embodiment, the terminal may pre-generate a screen content layout set, wherein the non-fully expanded ratio refers to the ratio corresponding to when the vehicle screen is not fully expanded, and at this time, the screen size of the vehicle screen does not belong to the conventional screen size, and the terminal needs to adapt the screen content layout for each non-fully expanded ratio, so that when the vehicle screen is in a non-fully expanded ratio, the screen projected by the terminal's target application onto the vehicle screen is still adapted.

[0104] For example, for a non-fully expanded ratio, the terminal can determine the content projection range and non-content projection range corresponding to the vehicle-mounted screen. The content projection range indicates the range where the picture content is projected on the vehicle-mounted screen, and the non-content projection range indicates the projection range where there is no picture content on the vehicle-mounted screen. For different non-fully expanded ratios, there are 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 application content of the target application in the content projection range. Among them, the application content represents the various elements in the application interface of the target application, and the terminal can adjust the projection layout of the application content to form a projection layout in each content projection range.

[0105] The terminal can obtain the screen content layout according to the preset content layout and the effective content layout acting on the non-content projection range. The terminal can generate different screen content layouts for different non-complete expansion ratios. Then the terminal can obtain a screen content layout set according to the screen content layout corresponding to each expansion ratio. Thus, the terminal can use the above screen content layout set to adjust the projection screen.

[0106] Specifically, as shown in FIG5 , FIG5 is a schematic diagram of the change of the screen content layout in one embodiment. Taking the screen of lifting the vehicle-mounted screen by 50% as an example, the screen unfolding by 50% indicates a non-complete unfolding ratio. At this time, the terminal can determine the target screen content layout that meets the unfolding ratio of the vehicle-mounted screen by 50% from the screen content layout set, such as adjusting the position and size of the lyrics and characters in FIG5 to form an effective content layout that meets the content projection range. For the non-content projection range, the terminal can control the screen within the range to be black, so that when the vehicle-mounted projection device projects the above-mentioned projection screen, the content layout part will be projected normally, and the non-content layout part will not emit light. At this time, the actual projection pixel of the vehicle-mounted projection device is still 100%. Taking the maximum size of the vehicle-mounted screen as 1920*1080, and adjusting the vehicle-mounted screen from unfolding 100% to unfolding 50% as an example, the size of the projection screen can be changed from 1920*1080 to 1920*540. By controlling the color of the non-content part to be black that does not emit light during projection, the screen content layout and the unfolding ratio are adapted.

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

[0108] In an exemplary embodiment, as shown in FIG6 , a vehicle-mounted projection control method is provided, which is described by taking the method applied to the controller in FIG1 as an example, and includes the following steps S602 to S604. Among them:

[0109] Step S602, controlling the vehicle-mounted screen to unfold to a first unfolding ratio; the vehicle-mounted screen at the first unfolding ratio is used to project a first projection screen of a target application; and the screen content layout of the first projection screen is adapted to the first unfolding ratio.

[0110] The vehicle-mounted screen can be controlled by a controller or by voice commands. For example, the controller controls the vehicle-mounted screen to unfold to a first unfolding ratio. The first unfolding ratio can be a fully unfolded ratio or a partially unfolded ratio. In the case of the first unfolding ratio, the vehicle-mounted screen can be used to project a first projection screen of the target application, and the screen content layout of the first projection screen is adapted to the first unfolding ratio.

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

[0112] The projection adjustment instruction may include an adjustment instruction for the expansion ratio of the vehicle screen, and may also include an adjustment instruction for the selection of a target application. The controller may respond to the projection adjustment instruction and control the vehicle screen to expand to a second expansion ratio. In the case of the second expansion ratio, the screen content layout of the second projection screen is adapted to the second expansion ratio, and the first expansion ratio and the second expansion ratio are different.

[0113] If the projection adjustment instruction is initiated by the controller, the controller can obtain a screen control instruction in response to the projection adjustment instruction. The screen control instruction can be an instruction to actively control the expansion ratio of the vehicle-mounted screen. The controller can control the vehicle-mounted screen to expand to the second expansion ratio according to the screen control instruction.

[0114] If the projection adjustment instruction is initiated by the target application in the terminal, the controller can obtain a screen control instruction of the vehicle-mounted projection device in response to the projection adjustment instruction. The screen control instruction can be an instruction for adapting the layout of the screen content of the second projection screen of the target application. The controller can control the vehicle-mounted screen to expand to the second expansion ratio according to the screen control instruction.

[0115] In the above-mentioned vehicle projection control method, the first projection screen of the target application that is adapted to the first expansion ratio of the screen content layout is projected to the vehicle screen of the first expansion ratio through the vehicle projection device, and in response to the projection adjustment instruction triggered in the target application or triggered by the controller, the second projection screen of the target application that is adapted to the second expansion ratio is projected to the vehicle screen of the second expansion ratio. Compared with the traditional projection of the screen with a fixed size, this solution makes the screen content layout adapt to the expansion ratio of the screen without interrupting the use of the application through the infinite adjustment of the screen or the adjustment of the awakened application, thereby improving the adaptability between the screen and the application of the vehicle projection.

[0116] In an exemplary embodiment, as shown in FIG. 7, FIG. 7 is a flow chart of a vehicle projection control method in another embodiment. In this embodiment, the above-mentioned projection adjustment instruction includes a projection adjustment instruction for the target application and an adjustment instruction for the vehicle screen. Among them, for the projection adjustment instruction triggered in the target application, since the height of the screen can be adjusted, the terminal can design an adaptive application interface, and the height of the screen can be adjusted in linkage by selecting the application function. For example, the above-mentioned vehicle screen is first fully unfolded, that is, 100% unfolded, and the terminal detects the selection instruction of the target application, determines whether the target application is a full-screen application, and if so, the terminal sends the projection screen of the target application to the vehicle projection device to project the screen content of the target application. If the target application is not a full-screen application, the terminal sends the projection screen of the target application containing the screen content part and the screen content part to the vehicle projection device, and the vehicle projection device controls the vehicle screen to adjust to the adapted height based on the projection screen, that is, the adapted unfolding ratio, for example, the vehicle target is raised by 50%, so that the unfolding ratio of the vehicle screen is adapted to the projection screen of the target application.

[0117] For the projection adjustment instruction triggered for the vehicle-mounted screen, the adaptive interface of the application can be automatically called up by controlling the height of the screen. For example, the above-mentioned vehicle-mounted screen is first fully unfolded, that is, 100% unfolded. The controller detects the screen control instruction, such as controlling the vehicle-mounted screen to rise 50%, and the target application being displayed needs to adjust the screen content layout to adapt to the unfolding ratio of the adjusted vehicle-mounted screen. The controller sends the adjustment information to the vehicle-mounted projection device, and the vehicle-mounted projection device requests the second projection screen of the target application from the terminal. The terminal detects whether there is an adaptive interface for the target application, for example, from the screen content layout set. If there is no screen content layout that is adapted to the current unfolding ratio of the vehicle-mounted screen, the vehicle-mounted projection device will continue to play and project the target application according to the current screen content layout. If there is a screen content layout that is adapted to the current unfolding ratio of the vehicle-mounted screen, the terminal will send the second projection screen that adapts the unfolding ratio to the vehicle-mounted projection device, and the vehicle-mounted projection device projects the second projection screen to the above-mentioned adjusted vehicle-mounted screen, and the use of the application is not interrupted during the process.

[0118] Through the above embodiments, when the screen is infinitely adjusted or the application is awakened, the layout of the screen content is adapted to the unfolding ratio of the screen without interrupting the use of the application, thereby improving the compatibility between the screen and the application of the vehicle projection. In addition, when adjusting the height of the screen, the adaptive interface application will not interrupt the use of the application, and the application and the screen can cooperate well. The full-screen application will terminate its use or fail to bring a reasonable experience. In addition, the non-full-screen screen projection can show the scene in front of the car, giving the user a sense of transparency in space. The non-full-screen screen projection leaves space for communication between users in the front and rear rows, and can also pass objects, thereby improving the utilization rate of the space in the car.

[0119] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
