Description

Technical Field

[0001] The present invention relates to the field of in-vehicle device control, and particularly to an in-vehicle projection system, a control method thereof, and a vehicle. Background Art

[0002] With the development of the automotive industry, the in-vehicle networking function has also evolved, and in-vehicle entertainment devices and in-vehicle computer components can all be controlled through an operating system.

[0003] Traditional control operations need to be implemented by the user through manual touchscreens or buttons. However, for the driver, during driving, controlling through manual touchscreens or buttons provides a poor user experience and is not conducive to driving safety. For passengers sitting in the back row, it is difficult to participate in the control of the entertainment operating system or the in-vehicle computer screen, and their experience is also not good.

[0004] With the development of speech recognition technology, some control operations can be implemented through the in-vehicle speech recognition function. For example, controlling the opening, switching, and volume adjustment of the entertainment system, etc., which greatly improves the user experience of the driver and passengers and is also more conducive to driving safety.

[0005] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art just because these solutions are described in the background art part of the present invention. Summary of the Invention

[0006] The inventor found that through voice command control, all users in the vehicle can control the entertainment system. However, since only the result feedback of the voice command can be heard, the process of voice control cannot be intuitively seen, lacking interest. In addition, sometimes the result of the regulation cannot be immediately confirmed. Therefore, when a voice recognition error leads to a regulation error, it cannot be discovered in time, and the feeling of directly operating the entertainment system cannot be provided.

[0007] In order to solve at least one of the above-mentioned existing technical problems, the present invention provides an in-vehicle projection system, a control method thereof, and a vehicle, which can enable users to intuitively see the execution process of the command, increase interest, and improve the user experience.

[0008] According to the first aspect of an embodiment of the present invention, an in-vehicle projection system is provided, and the in-vehicle projection system includes:

[0009] A control device, which receives a user's command, obtains a display interface related to the operation of the command, and determines the position of the user in the vehicle according to the command;

[0010] a projection device, which projects the display interface to a predetermined area in the vehicle corresponding to the position of the user,

[0011] The control device starts to execute the operation of the user's command, and the display interface displays the process of the control device executing the operation of the user's command.

[0012] Furthermore, by projecting the display interface related to the operation of the command issued by the user to a suitable area visible to the user, the user can intuitively see the execution process of the command, which increases interest, improves user experience, and creates an intuitive feeling of the user himself in the operation interface.

[0013] According to a second aspect of an embodiment of the present invention, the display interface includes a first interface before executing the operation of the command, and / or a second interface for executing the operation to complete the command, and / or a third interface during the process from before executing the operation of the command to completion of the operation of the command.

[0014] Furthermore, the interface for executing the user's command process is displayed to the user, so that the user can intuitively see the process of executing his or her command, as well as the changes before and after the adjustment, which can enable the user to have an immersive experience and enhance the riding experience.

[0015] According to a third aspect of the embodiments of the present invention, the predetermined area includes at least one projection area, and the position of the projection area is determined based on the position of the user in the car, or the position of the user in the car and the number of users.

[0016] Furthermore, the projection area is determined based on the position of the user, or the position and number of the user, so that the projection area corresponds to the user, which allows the user to see the projected image intuitively, which is more user-friendly.

[0017] According to a fourth aspect of an embodiment of the present invention, the position of the user includes an area where the user is located in the vehicle, and / or a seat where the user is located in the vehicle.

[0018] Furthermore, the user's position can be determined by the area in the car, such as the front row, the back row, etc., or by the user's seat in the car, such as the right seat in the back row, etc. In this way, the reserved area can be set accordingly based on the user's position, and can be set based on actual needs to suit the user's preferences.

[0019] According to a fifth aspect of the embodiments of the present invention, the predetermined area includes the area in front of the user in the vehicle and / or the area in front of the seat in the vehicle.

[0020] Further, the predetermined area can be determined based on the setting method of the user's location, corresponding to the area inside the vehicle, located in front of the area inside the vehicle, or corresponding to a certain seat and located in front of a certain seat. In this way, the setting of the predetermined area can be based on actual needs to meet the user's preferences.

[0021] According to the sixth aspect of the embodiments of the present invention, the predetermined area includes a plurality of projection areas, and each seat inside the vehicle corresponds to one of the projection areas. When the control device receives a user's command, based on the seat where the user is located, the corresponding projection area is determined, and the projection device projects the display interface onto the corresponding projection area.

[0022] According to the seventh aspect of the embodiments of the present invention, the predetermined area includes a plurality of projection areas, and the space inside the vehicle is virtually divided into a plurality of divided areas, and each divided area corresponds to one of the projection areas. When the control device receives a user's command, based on the divided area where the user is located, the corresponding projection area is determined, and the projection device projects the display interface onto the corresponding projection area.

[0023] Further, a solution is given when the projection area corresponds to a seat or a divided area inside the vehicle. Based on the user's needs and the actual situation, the projection area can be correspondingly set, so as to meet the user's needs while simplifying the setting of the projection area as much as possible.

[0024] According to the eighth aspect of the embodiments of the present invention, the control device also obtains the seat and / or the number of users in the divided area, and the projection device adjusts the position of the projection area corresponding to the divided area according to the seat and / or the number of users in the divided area.

[0025] According to the ninth aspect of the embodiments of the present invention, the space inside the vehicle is divided into the plurality of divided areas based on the location and / or the number of users.

[0026] Further, the divided areas can be divided based on the situation inside the vehicle at that time, such as the location and number of users inside the vehicle. While meeting the user's intuitive view of the display interface, the most optimized area division is given. For example, when there are passengers on both the left and right sides of the rear row, the entire rear row can be used as a divided area, so that the display interface is projected to the middle of the rear row area, so that users on both sides can see it. If there are passengers in the left seat and the middle seat of the rear row, the left seat and the middle seat of the rear row can also be used as a divided area, and the specific position of the display interface in the projection area can be set to the front of the middle of the left seat and the middle seat. The specific position of the display interface in the projection area can also be adjusted according to the user's needs, so as to better meet the user's personalized needs.

[0027] According to the tenth aspect of the embodiments of the present invention, the predetermined area includes at least one projection area, and the projection device projects more than two display interfaces simultaneously within the at least one projection area.

[0028] Furthermore, different display interfaces can be simultaneously displayed within one projection area. In this way, under the condition of reasonable projection area setting, the needs of different users can also be met.

[0029] The projection device may also include at least one projection unit, and the at least one projection unit includes a three-dimensional projection unit and / or a two-dimensional projection unit.

[0030] Furthermore, the projection unit can be selected as a two-dimensional and / or three-dimensional projection unit, which is selected based on actual needs or device requirements to expand applicability.

[0031] According to the eleventh aspect of the embodiments of the present invention, the commands include voice commands and / or gesture commands.

[0032] Furthermore, by recognizing voice commands or gesture commands, the needs of different groups of people can be met, and the service group of the product can be expanded.

[0033] According to the twelfth aspect of the embodiments of the present invention, the display interface includes an interface related to in-vehicle entertainment equipment, and the control device acquires the interface of the in-vehicle entertainment equipment according to the command.

[0034] Furthermore, the interface of the in-vehicle entertainment equipment is displayed in front of the user by projection, creating a feeling that the user is operating the in-vehicle entertainment equipment by himself.

[0035] According to the thirteenth aspect of the embodiments of the present invention, the in-vehicle projection system further includes a mounting device, and the mounting device movably and / or rotatably mounts the projection device. The projection device controls the mounting device to move and / or rotate according to the position of the user, and projects the display interface onto the predetermined area.

[0036] Furthermore, after determining the predetermined area, the projection area of the projection device is adjusted through the mounting device. With one projection device, projection at any position within the whole vehicle area can be achieved, which can make the projection area more suitable for the user to watch and further enhance the user's riding experience.

[0037] According to the fourteenth aspect of the embodiments of the present invention, the specific projection position of the display interface within the predetermined area changes correspondingly based on the change of the user's line of sight and / or the user's face orientation.

[0038] And / or, the specific projection position of the display interface within the predetermined area moves to another position based on the user's operation.

[0039] Further, by controlling the specific projection position of the display interface in the predetermined area based on the user's line of sight, face orientation, operations, etc., the display interface is made to follow the user's line of sight or the user's will for display, enabling the user to intuitively see the display interface regardless of the state, and further enhancing the user's in-vehicle experience. At the same time, based on the user's own operations, the display interface can also be projected and displayed at the required position to meet the personalized needs of the user.

[0040] According to the fifteenth aspect of the embodiments of the present invention, the display interface is projected in the predetermined area and maintained for a predetermined time. In the case where a second command is detected to be input by the user to the display interface projected in the predetermined area within the predetermined time, a display interface showing the operation process of executing the second command is displayed in the predetermined area.

[0041] Further, by detecting the second command input by the user to the display interface and displaying the execution process of the second command, the user can continuously watch the execution process of the command without a sense of interruption, further enhancing the user's in-vehicle experience.

[0042] According to the sixteenth aspect of the embodiments of the present invention, a virtual image is included in the display interface, and the process of the virtual image executing the user's command is displayed in the display interface.

[0043] Further, by displaying the process of the virtual image executing the user's command in the display interface, the virtual image is made to move, rather than just boringly watching the display interface, further increasing the fun.

[0044] According to the seventeenth aspect of the embodiments of the present invention, when the control device receives multiple commands from multiple users, based on the position of each user, the display interface corresponding to each user's command is projected onto each predetermined area corresponding to the position of each user;

[0045] Or, when the control device receives multiple commands from multiple users, the multiple display interfaces corresponding to the multiple commands of the multiple users are projected onto at least one predetermined area corresponding to the positions of the multiple users.

[0046] Further, each user has a dedicated projection area, which can provide personalized correspondence even when multiple users are present and can also meet the different needs of each user. Of course, according to the needs of the users, the display interfaces corresponding to multiple users can also be displayed in the same predetermined area, which can meet the needs of different users while reasonably setting the projection area.

[0047] According to the eighteenth aspect of the embodiments of the present invention, a control method for an in-vehicle projection system is provided, and the control method includes:

[0048] Receive a user's command and obtain a display interface related to the operation of the command.

[0067] Referring to the accompanying drawings, through the following description, the foregoing and other features of the present invention will become apparent. In the description and drawings, specific embodiments of the present invention are specifically disclosed, which show some embodiments in which the principles of the present invention can be adopted. It should be understood that the present invention is not limited to the described embodiments, but includes all modifications, variations, and equivalents falling within the scope of the appended claims.

[0068] The following describes the in-vehicle projection system, its control method, and the vehicle according to the embodiments of the present invention with reference to the accompanying drawings.

[0069] Embodiment 1

[0070] Embodiment 1 of the present invention provides an in-vehicle projection system. Figure 1 It is a schematic block diagram of the in-vehicle projection system according to Embodiment 1 of the present invention.

[0071] As Figure 1 shown, the in-vehicle projection system 1 includes a control device 10 and a projection device 20. The control device 10 is configured to receive a user's command, obtain a display interface related to the operation of the command, and determine the user's position in the vehicle according to the command. The projection device 20 is configured to project the display interface onto a predetermined area corresponding to the user's position, and the control device 10 executes the operation of the user's command, and the display interface displays the process of the control device 10 executing the operation of the user's command.

[0072] Thus, by projecting the display interface related to the operation of the command issued by the user onto a suitable area visible to the user, the user can intuitively see the execution process of the command, increasing the fun and enhancing the user experience, creating an intuitive feeling that the user is operating the interface himself.

[0073] In the embodiment of the present invention, the user's command can be a voice command or a gesture command. For example, the user's voice command can be recognized by a voice recognition chip, or the user's gesture can be captured by a camera device and then the user's gesture command can be recognized by an image recognition chip. In addition, the voice recognition chip and / or the image recognition chip can be integrated in the control device 10, so that the control device 10 can directly obtain the recognized command. The voice recognition chip and / or the image recognition chip can also be integrated in a device such as a processor independent of the control device 10, and then the recognized command can be sent to the control device 10 by means of, for example, a wired or wireless communication link. The specific implementation method can refer to the related technology, and the embodiment of the present invention does not limit this.

[0074] In this way, by recognizing voice commands or gesture commands, the needs of different people can be met, and the service group of the product can be expanded.

[0075] In the embodiment of the present invention, the control device 10 can determine the position of the user in the vehicle according to the command. For example, when the user uses a voice command, the control device 10 can detect the orientation of the user through a sound sensor arranged in the vehicle and judge the position of the user; or, the control device 10 can also obtain the image in the vehicle through the camera device in the vehicle and judge the position of the user according to the image analysis; or, the control device 10 can also judge the position of the user by combining the seat sensor and the sound sensor in the vehicle. The specific implementation manner can refer to the related technology, and the embodiment of the present invention does not limit this.

[0076] In the embodiment of the present invention, the display interface can include a first interface before the operation of executing the command, and / or the display interface includes a second interface after the operation of executing the command is completed, and / or the display interface includes a third interface during the process from before the operation of executing the command to the completion of the operation of the command.

[0077] In this way, the interface of the process of executing the user's command is displayed to the user, so that the user can intuitively see the execution process of his own command, as well as the changes before and after the regulation, enabling the user to obtain an immersive experience and enhancing the riding experience.

[0078] For example, as Figure 1As shown, the vehicle interior may further include in-vehicle entertainment device 30 and in-vehicle head unit device 40. The in-vehicle entertainment device 30 and the in-vehicle head unit device 40 may be components of the in-vehicle projection system 1, or may be relatively independent parts from the in-vehicle projection system 1. The in-vehicle entertainment device 30 and the in-vehicle head unit device 40 may also be integrated together. The embodiments of the present invention do not limit this. The control device 10 and the in-vehicle entertainment device 30 or the in-vehicle head unit device 40 may be integrated together or may be relatively independently arranged. For example, the control device 10 may be built into the in-vehicle entertainment device 30. The embodiments of the present invention do not limit this.

[0079] In some embodiments, the display interface may be an interface related to the in-vehicle entertainment device 30, or a schematic interface of the in-vehicle head unit device 40. For example, the in-vehicle entertainment device 30 includes a music player. The music player may be a software application installed in the operating system or a hardware player. The display interface may be various pre-set user interaction interfaces in the music player application or a schematic interface representing the music player, such as an interface of a rotating record player. Taking the music player application as an example, the user's command may be, for example, "Open the music player". The first interface may be, for example, an interface showing the icon of the application of the music player. The second interface may be, for example, an interactive interface when the application of the music player is being opened. The third interface may be, for example, all the interfaces during the process of switching from the interface showing the icon of the music player to the interface after the music player application is opened.

[0080] Another example is that the in-vehicle head unit device 40 includes an air-conditioning interface. The display interface may be a sliding bar representing the set temperature of the air conditioner, or a gradient bar of warm and cold colors, or an expression picture corresponding to the set temperature, etc. Taking the sliding bar as an example, the user's command may be, for example, "Set the vehicle interior temperature to 24 degrees". The first interface may be an interface showing the position of the sliding block on the sliding bar representing the current vehicle interior temperature. The second interface may be an interface showing the position of the sliding block on the sliding bar representing 24°C. The third interface may be an interface showing the sliding block sliding on the sliding bar from the position representing the current vehicle interior temperature to the position representing 24°C.

[0081] In the embodiments of the present application, the projection device 20 may project at least one of the first interface, the second interface, and the third interface. For example, it may first project the first interface, then the third interface, and then the second interface, or it may only project the second interface, or it may also only project the third interface, or it may also only project the first interface. Which interface or which interfaces to project specifically can be set according to the user's command, as long as it can enable the user to see the execution process and result of the command after issuing the command. Of course, the first interface, the second interface, and the third interface may be static interfaces frame by frame or dynamic interfaces, which is not limited herein.

[0082] In this way, by displaying the interface related to the execution of the command to the user for viewing, the user can obtain an immersive experience and enhance the riding experience.

[0083] Next, the projection area of the display interface will be described.

[0084] Figure 2 It is a schematic diagram for explaining the projection area of the in-vehicle projection system according to Embodiment 1 of the present invention.

[0085] As Figure 2 shown, taking the example of placing two rows of seats in the vehicle, the space inside the vehicle can be virtually divided into multiple divided areas. For example, it is divided into a front row area 201 and a rear row area 202 by the dashed line L1; the space inside the vehicle can also be divided according to different seats. For example, the driver's seat 211, the co-driver's seat 212, the left rear seat 221, the right rear seat 222, and the middle rear seat 223; the specific setting of the divided area can be user-defined based on the user's needs, or several area division modes can be preset in the system for the user to select based on their needs. The specific setting of the divided area is not limited in the embodiments of the present invention.

[0086] In the embodiments of the present invention, the direction parallel to the vehicle length direction is referred to as the "front-back direction", the direction parallel to the vehicle height direction is referred to as the "up-down direction", and the direction parallel to the vehicle width direction is referred to as the "left-right direction".

[0087] In addition, the embodiments of the present invention take the example of placing two rows of seats in the vehicle for description, but those skilled in the art should understand that for the case of placing other numbers of seats in the vehicle, the division of the space inside the vehicle can be analogized. The embodiments of the present invention can also be applied to the case of placing other numbers of seats in the vehicle, and will not be repeated in the following embodiments.

[0088] In the embodiments of the present invention, the position of the user can include the area where the user is located inside the vehicle and / or the seat where the user is located inside the vehicle. For example, as Figure 2 shown, it can be determined that the user is in the front row area 201 according to the command issued by the user, or it can also be determined that the user is in the left rear seat 221 according to the command issued by the user.

[0089] In the embodiments of the present invention, the predetermined area can include the front of the area where the user is located inside the vehicle and / or the front of the seat where the user is located inside the vehicle. For example, as Figure 2As shown, when it is determined that the user is in the rear row area 202, the display interface can be projected in front of the rear row area 202. For example, it can be projected onto the back of the front row seat; or, when it is determined that the user is in the co-pilot seat 212, the display interface can be projected in front of the co-pilot seat 212. For example, it can be projected onto the front windshield or onto the road surface in front of the vehicle during travel; or the display interface can also be projected into the air in front of the area where the user is located through holographic projection, enabling the display interface to be visible within the user's line of sight.

[0090] In this way, based on the user's position, or the user's position and quantity, the projection area is determined, so that the projection area corresponds to the user, enabling the user to intuitively see the projected image.

[0091] In addition, the user's position can be determined by the area where the user is located in the vehicle, such as the front row, rear row, etc., or can be determined by the user's seat in the vehicle, such as the rear right seat, etc. In this way, the predetermined area can be correspondingly set based on the user's position and can be set according to actual needs to conform to the user's preferences.

[0092] In some embodiments, the control device 10 can determine the area where the user is located in the vehicle according to the received command, and the projection device 20 projects the display interface in front of the area where the user is located.

[0093] Such as Figure 2 As shown, for example, if a user located in the driver's seat 211 or the co-pilot seat 212 issues a command, then the control device 10 determines that the user is in the front row area 201 according to the received command, and the projection device 20 projects the display interface in front of the front row area 201. For example, it is projected onto the front row projection area p1, and the front row projection area p1 is, for example, located at the middle position in front of the front windshield or in the air in front of the front row seat.

[0094] Or, for example, if a user located in the left rear seat 221, right rear seat 222, or middle rear seat 223 issues a command, then the control device 10 determines that the user is in the rear row area 202 according to the received command, and the projection device 20 projects the display interface in front of the rear row area 202. For example, it is projected onto the rear row projection area p2, and the rear row projection area p2 is, for example, located at the middle position between the backrests of the two front row seats.

[0095] In some embodiments, the control device 10 can determine the seat where the user is located in the vehicle according to the received command, and the projection device 20 projects the display interface in front of the seat where the user is located.

[0096] Such as Figure 2As shown, for example, if the control device 10 determines that the command is issued by the user located at the rear right seat 222 based on the received command, then the projection device 20 projects the display interface onto the projection area p6 in front of the rear right seat 222. Additionally, the projection area corresponding to the driver's seat 211 is p3, the projection area corresponding to the front passenger seat 212 is p4, the projection area corresponding to the rear left seat 221 is p5, and the projection area corresponding to the middle rear seat 223 is p2.

[0097] In the embodiments of the present invention, the predetermined area may include at least one projection area. For example, as Figure 2 shown, the predetermined area may include the projection area p1, or the predetermined area may also include the projection areas p1 to p6.

[0098] In some embodiments, the position of the projection area is determined based on the position of the user in the vehicle or the position of the user in the vehicle and the number of users. For example, if the user in the vehicle is in the front row area 201, then the projection area p1 can be determined as the projection position of the display interface; for another example, if there are 2 users in the front row area 201, then the projection areas p3 and p4 can be determined as the projection positions of the display interface.

[0099] In some embodiments, each seat in the vehicle may correspond to a projection area. When the control device 10 receives the user's command, based on the seat where the user is located, the corresponding projection area is determined, and the projection device 20 projects the display interface onto the corresponding projection area. For example, as Figure 2 shown, each seat in the vehicle corresponds to a projection area. The driver's seat 211 corresponds to the projection area p3, the front passenger seat 212 corresponds to the projection area p4, the rear left seat 221 corresponds to the projection area p5, the rear right seat 222 corresponds to the projection area p6, and the middle rear seat 223 corresponds to the projection area p2. When the control device 10 receives the user's command, it can determine the seat where the user is located according to the user's command. For example, for the rear left seat 221, it is determined that the corresponding projection area is the projection area p5, and the projection device 20 projects the display interface onto the projection area p5.

[0100] For example, the predetermined area where the projection device 20 projects may include multiple projection areas corresponding to the seats in the vehicle. The control device 10 can obtain the number of users in the vehicle and the seat where each user is located in the vehicle. The projection device 20 determines the number of projection areas according to the number of users in the vehicle, and projects the display interface onto the corresponding projection area according to the seat where each user is located in the vehicle.

[0101] As Figure 2As shown, for example, the projection device 20 can project the display interface onto areas p2 to p6 corresponding to the seats in the vehicle. The control device 10, for example, obtains that there are 3 users in the vehicle, and these 3 users are respectively in the driver's seat 211, the co-driver's seat 212, and the left rear seat 221. The projection device 20 can determine that projections need to be made in 3 projection areas, namely, the projection area corresponding to the driver's seat 211 is p3, the projection area corresponding to the co-driver's seat 212 is p4, and the projection area corresponding to the left rear seat 221 is p5, and project the display interface into these projection areas. In the same situation, the driver's seat 211 and the co-driver's seat 212 can correspond to one projection area, that is, the projection area p1, and the left rear seat 221 corresponds to the projection area p5. The specific setting of the projection area can be based on the actual needs of users or custom settings.

[0102] In this way, by projecting the display interface onto the visible areas of each user in the vehicle, the setting of the projection area is more user-friendly, enabling each user to have a sense of participation and enhancing the riding experience.

[0103] For example, the predetermined areas for the projection device 20 to project can include multiple projection areas corresponding to multiple divided areas in the vehicle. The control device 10 can obtain the divided areas where all users in the vehicle are located, and the projection device 20 projects the display interface onto the corresponding projection areas according to the divided areas where all users are located.

[0104] As Figure 2 shown, for example, the multiple divided areas in the vehicle are the front row area 201 and the rear row area 202. The projection areas for the projection device 20 to project are the front row projection area p1 corresponding to the front row area 201 and the rear row projection area p2 corresponding to the rear row area 202. It is determined whether to project the display interface onto the front row projection area p1 or the rear row projection area p2 according to whether the user is in the front row area 201 or the rear row area 202. For example, if the control device 10 determines that all users in the vehicle are in the front row area 201, the projection device 20 projects the display interface onto the front row projection area p1 corresponding to the front row area 201; in addition, if the control device 10 determines that all users in the vehicle are in the rear row area 202, the projection device 20 projects the display interface onto the rear row projection area p2 corresponding to the rear row area 202; in addition, if the control device 10 determines that there are users in both the front row area 201 and the rear row area 202, then the projection device 20 projects the display interface in both the front row projection area p1 and the rear row projection area p2.

[0105] In this way, by projecting the display interface onto the areas where all users are located, all users can see the control process of the command, enhancing the riding experience.

[0106] In addition, since the projection area can be set according to user requirements and actual conditions, the setting of the projection area can be simplified as much as possible while meeting user needs.

[0107] In some embodiments, the control device 10 may further obtain the seat and / or number of users within the divided area, and the projection device 20 adjusts the position of the projection area corresponding to the divided area according to the seat and / or number of users within the divided area.

[0108] As Figure 2 shown, for example, when the control device 10 obtains that there is 1 user in the rear row area 202, located at the left rear seat 221, the projection device 20 may move the projection area p2 corresponding to the rear row area 202 to the front of the left rear seat 221. For example, move the projection area p2 to the position where the projection area p5 is located. Or, the projectable area of the projection device 20 includes the projection areas p2 and p5. In this case, the projection device 20 may choose to project the display interface onto the area p5. Another example is that when the control device 10 obtains that there are 2 users in the rear row area 202, located at the left rear seat 221 and the middle rear seat 223 respectively, the projection device 20 may move the projection area p2 corresponding to the rear row area 202 in the direction of the projection area p5. For example, move it to the position in the middle between the projection area p2 and the projection area p5 to facilitate the user at the left rear seat 221 to view.

[0109] Another example is that during driving, the control device 10 determines that all users in the vehicle are in the front row area 201 and determines that there is only 1 user in the front row area 201. Then it can be presumed that the user on the driver's seat 211 issued the command. In this case, the projection device 20 may move the projection area to the front of the driver's seat 211. For example, move the projection area from p1 to p3. However, it can also be that the projectable area of the projection device 20 includes the projection areas p1 and p3. In this case, the projection device 20 may choose to project the display interface onto the area p3.

[0110] In this way, by determining the seat and / or number of users within the area, the projection area can be set more reasonably to meet the user's need to view the interface, enabling the user to watch the control process of the command more comfortably. At the same time, unnecessary complex settings can be omitted, making it more user-friendly and further enhancing the riding experience.

[0111] In addition, the divided area can be divided based on the situation inside the vehicle at that time, such as the positions and numbers of users in the vehicle, to give the most optimized area division while allowing users to directly see the display interface. For example, when there are passengers on both the left and right sides of the rear row, the entire rear row can be used as a divided area, and the display interface can be projected to the middle of the rear row area so that users on both sides can see it.

[0112] In some embodiments, when the control device 10 receives multiple commands from multiple users, based on the location of each user, the display interface corresponding to each user's command is projected onto each predetermined area corresponding to the location of each user.

[0113] For example, as Figure 2 shown, the user sitting in the co-pilot seat 212 issues command C1, and the user sitting in the middle rear seat 223 issues command C2. The control device 10 receives command C1 and command C2, and determines that command C1 comes from the user in the co-pilot seat 212 according to command C1, and determines that command C2 comes from the user in the middle rear seat 223 according to command C2. The control device 10 projects the display interface A1 corresponding to command C1 onto the predetermined area corresponding to the co-pilot seat 212 (for example, projection area p4), and projects the display interface B1 corresponding to command C2 onto the predetermined area corresponding to the middle rear seat 223 (for example, projection area p2).

[0114] In addition, multiple commands from multiple users can be received simultaneously, and the control device 10 can simultaneously display multiple display interfaces corresponding to multiple commands in the corresponding predetermined areas respectively. For example, in the above example, the control device 10 receives command C1 and command C2 simultaneously, and the control device 10 can project the display interface A1 and the display interface B1 onto the projection area p4 and the projection area p2 respectively at the same time. The control device 10 can also display multiple display interfaces corresponding to multiple commands in one predetermined area. For example, in the above example, two users are respectively located in the rear row area. When the control device 10 receives the commands C1 and C2 of the two users, the control device 10 can project the display interface A1 and the display interface B1 onto the projection area p2 corresponding to the rear row area at the same time, that is, multiple display interfaces can be projected in one projection area at the same time.

[0115] It should be noted that the "simultaneously" described in the embodiments of the present invention does not necessarily mean absolute synchronization in time, and it can refer to synchronization to a certain extent. For example, there is a certain overlap in time between the issuance of command C1 and the issuance of command C2, then there is also a certain overlap in time between the time when the control device 10 receives command C1 and the time when it receives command C2, and it can be considered that these two commands are simultaneous. For example, it is judged whether the overlap time is within a predetermined time, and if it is within the predetermined time, it is considered simultaneous. The predetermined time is, for example, 2 seconds, and the embodiments of the present application do not limit this. In this case, the control device 10 can project the display interface A1 and the display interface B1 onto the projection area p4 and the projection area p2 respectively at a predetermined time interval.

[0116] In this way, each user has a dedicated projection area, and even when multiple users exist, personalized correspondence can be provided, and the different needs of each user can be met.

[0117] Figure 3 This is a schematic diagram for explaining the divided areas of the in-vehicle projection system according to Embodiment 1 of the present invention.

[0118] The above has taken the division of the space inside the vehicle into a front row area and a rear row area in the front-back direction as an example for explanation. However, the embodiments of the present application are not limited thereto, and the space inside the vehicle can also be divided into multiple divided areas based on the position and / or number of users. For example, as Figure 3 shown, if there are users in the driver's seat 211 and the left rear seat 221, then the space inside the vehicle can also be divided in the left-right direction. For example, it can be divided into a left area 301 and a right area 302 along the dotted line L2; or, it can also be divided into three divided areas, namely a divided area 303 centered on the driver's seat 211, a divided area 304 centered on the passenger seat 212, and a divided area 305 corresponding to the three rear seats, along the dotted lines L2 and L3; or, if there is only one user in the vehicle, then the seat where the user is located can be divided into a divided area, and the other space inside the vehicle can be divided into another divided area. How to specifically divide the multiple divided areas can be predefined or user-defined, and the embodiments of the present invention do not limit this.

[0119] In some embodiments, the projection device 20 may include at least one projection unit. For example, as Figure 2 shown, six projection units can be correspondingly set for the projection areas p2 to p6 corresponding to all seats, or two projection units can be correspondingly set for the projection areas p1 and p2 corresponding to two divided areas (such as the front row area 201 and the rear row area 202). In addition, only one projection unit can also be set to form multiple projection interfaces by using one projection unit.

[0120] In addition, the projection unit can also be moved, so that projection can be performed in multiple areas. For example, as Figure 1 shown, the in-vehicle projection system 1 may further include a mounting device 50 for mounting the projection device 20, and the mounting device 50 can move and / or rotate. The projection device 20 can control the movement of the mounting device 50 according to the position of the user, so as to project the display interface onto the area where projection is desired. For example, the slidable function of the mounting device 50 can be realized through a slide rail, the rotatable function of the mounting device 50 can be realized through a rotating cloud platform, and the movement of the mounting device 50 can also be realized through other related technologies. The embodiments of the present invention do not limit this.

[0121] In this way, by adjusting the projection area of the projection device through the mounting device, the projection area can be made more suitable for the user to watch, further improving the user's riding experience.

[0122] In addition, the projection device according to the embodiment of the present invention may be a two-dimensional projection device. For example, the projection areas p5 and p6 may be set to the back surface of the backrest of the front row seats, and the back surface of the backrest of the front row seats is used as a projection screen for projecting a display interface. The projection device may also be a three-dimensional projection device or a holographic projection device. For example, a projection device based on the principle of Pepper's ghost may be used to project a display interface in multiple projection areas. Specific implementation manners of the two-dimensional projection device and the three-dimensional projection device may refer to related technologies, and the embodiments of the present invention do not limit this.

[0123] Figure 4 and Figure 5 are schematic diagrams for explaining the projection positions of the in-vehicle projection system according to Embodiment 1 of the present invention.

[0124] In some embodiments, the specific projection position of the display interface in the predetermined area changes correspondingly based on the change of the user's line of sight and / or the user's face orientation, and / or the specific projection position of the display interface in the predetermined area moves to another position based on the user's operation.

[0125] For example, as Figure 4 shown, the user's line of sight changes from direction E1 to direction E2, or the user's face orientation changes from direction E1 to direction E2. The projection device 20 can move the display interface in the predetermined area PA from the projection position P1 corresponding to direction E1 to the projection position P2 corresponding to direction E2.

[0126] For another example, as Figure 5 shown, the user performs a sliding operation S on the display interface, and the position of the finger, for example, slides from position H1 to position H2. The projection device 20 can move the display interface in the predetermined area PA from the projection position P3 corresponding to position H1 to the projection position P4 corresponding to position H2.

[0127] In this way, the display interface can follow the user's line of sight or the user's will to further meet the user's viewing needs at that time and further improve the user's in-vehicle experience.

[0128] Figure 6 is a schematic diagram for explaining the execution process of the display command of the display interface of the in-vehicle projection system according to Embodiment 1 of the present invention.

[0129] In some embodiments, the display interface is projected in the predetermined area and maintained for a predetermined time. When it is detected that the user inputs a second command to the display interface projected in the predetermined area within the predetermined time, a display interface for executing the operation process of the second command is displayed in the predetermined area.

[0130] For example, as Figure 6As shown, a display interface U1 is projected within a predetermined area. If another command is detected being input by the user to the display interface U1 within a predetermined time, for example, it is detected that the user clicks the play button B on the display interface U1 or a voice command for playing output by the user is detected, the control device 10 can display the next play interface U2 in this predetermined area. The above example of detecting that the user clicks a button on the display interface is used to illustrate that the user inputs a second command to the display interface, but the embodiments of the present invention are not limited thereto. For example, the second command input by the user to the display interface can also be determined by recognizing the user's voice instruction. The implementation manner of detecting a command input to the display interface can refer to related technologies, and the embodiments of the present invention do not limit this.

[0131] In this way, by detecting the second command input by the user on the display interface and displaying the execution process of this second command, the user can continuously watch the execution process of the command without a sense of interruption, further enhancing the user's in-vehicle experience.

[0132] Figure 7 FIG. is a schematic diagram for explaining projecting two or more display interfaces within the projection area of the in-vehicle projection system in Embodiment 1 of the present invention.

[0133] In some embodiments, the projection device 20 can simultaneously project at least two display interfaces within at least one projection area.

[0134] For example, as Figure 7 shown, the display interface U3 and the display interface U4 can be simultaneously projected within the projection area p1. The display interface U3 and the display interface U4 can be different display interfaces. The display interface U3 is, for example, a display interface obtained by performing an operation for executing a command issued by the user sitting in the driver's seat 211, and the display interface U4 is, for example, a display interface obtained by performing an operation for executing a command issued by the user sitting in the passenger seat 212. Of course, two different display interfaces corresponding to two commands issued by the same passenger can also be simultaneously projected within a projection area p1. For example, the display interface U3 can be a display interface obtained by performing an operation for a command to adjust the air conditioner issued by the passenger, and U4 can be a display interface obtained by performing an operation for a command to adjust the seat issued by the same passenger. In this way, the same passenger can also adjust different functions simultaneously and can directly see the display interfaces of the command execution processes at the same time, which is more user-friendly.

[0135] Thus, different display interfaces can be simultaneously displayed within one projection area, and the needs of different users can also be met under the condition of a reasonable projection area setting.

[0136] In some embodiments, the display interface can further include a virtual image, and the process of the virtual image performing the operation of the user's command is displayed in the display interface. Thereby, the fun is further increased.

[0137] As can be seen from the above embodiments, by projecting the display interface related to the operation of the command issued by the user onto a suitable area visible to the user, the user can intuitively see the execution process of the command, increasing the fun and enhancing the user experience.

[0138] Embodiment 2

[0139] Embodiment 2 of the present invention provides a control method for an in-vehicle projection system. Figure 8 It is a flowchart of the control method for the in-vehicle projection system according to Embodiment 2 of the present invention.

[0144] Step 704: Execute the operation of the user's command, and the display interface displays the process of executing the operation of the user's command.

[0145] Thus, by projecting the display interface related to the operation of the command issued by the user onto a suitable area visible to the user, the user can intuitively see the execution process of the command, increasing the fun and enhancing the user experience.

[0146] In some embodiments, in step 702, the area where the user is located in the vehicle can be determined according to the command.

[0151] In some embodiments, in step 702, it is also possible to obtain the seat and / or the number of the user in the divided area, and adjust the position of the projection area corresponding to the divided area according to the seat and / or the number of the user in the divided area in step 703.

[0152] In some embodiments, in step 703, the specific projection position of the display interface in the predetermined area changes correspondingly based on the change of the user's line of sight and / or the user's face orientation, and / or, the specific projection position of the display interface in the predetermined area moves to another position based on the user's operation.

[0153] In some embodiments, in step 703, the display interface is projected in the predetermined area and maintained for a predetermined time. In the case where a second command is detected to be input to the display interface projected in the predetermined area within the predetermined time, a display interface for executing the operation process of the second command is displayed in the predetermined area.

[0154] In some embodiments, the display interface includes a virtual image, and the process of the virtual image executing the operation of the user's command is displayed in the display interface.

[0155] In some embodiments, when receiving a plurality of commands from a plurality of users in step 701, in step 703, based on the position of each user, project the display interface corresponding to each user's command onto the predetermined area corresponding to the position where each user is located.
