Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to an in-vehicle projection system. Background Technology

[0002] With the improvement of in-car entertainment functions, in-car projectors have emerged. Currently, many vehicles are equipped with in-car projector devices, but using these devices can easily distract drivers and affect driving safety, and the user experience while watching movies needs improvement. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide an in-vehicle projection system that uses different display components to display the content to be projected under different vehicle conditions, thereby avoiding the projection from distracting the driver's attention.

[0004] To achieve the above objectives, embodiments of the present invention provide a vehicle-mounted projection system, comprising:

[0005] The first display unit is positioned in front of the driver;

[0006] The second display component is located in a different position inside the vehicle cabin than the location of the first display component described above.

[0007] Projection components;

[0008] Detection components are used to detect vehicle status;

[0009] The control module is configured to control the projection component to project the content to be projected onto the first display component in response to the vehicle state being a first vehicle state, and to control the projection component to project the content to be projected onto the second display component in response to the vehicle state being a second vehicle state.

[0010] Optionally, the second display component has a first position state and a second position state;

[0011] When the vehicle status is the first vehicle status, the second display component is in the first position state; when the vehicle status is the second vehicle status, the second display component is in the second position state.

[0012] Optionally, the first position state is a stored state, and the second position state is an unfolded state.

[0013] Optionally, the first position state is when the second display component is housed in a location other than in front of the driver in the vehicle cabin, and the second position state is when the second display component extends into the space inside the vehicle cabin.

[0014] Optionally, the control module is further configured to control the second display component to switch from the first position state to the second position state in response to the vehicle state being the second vehicle state.

[0015] Optionally, the first display component is disposed on the windshield in front of the driver.

[0016] Optionally, the first vehicle state is when the vehicle speed is less than a preset vehicle speed threshold, the gear is in parking gear, or the driving mode indicates that the vehicle is in assisted driving mode, and the projection component is performing projection.

[0017] The aforementioned second vehicle state is characterized by the vehicle speed being greater than a preset speed threshold, the gear being in non-parking gear, and / or the driving mode indicating that the vehicle is in non-assisted driving mode, and the aforementioned projection component being in the state of projection.

[0018] Optionally, the detection component is also used to acquire environmental data and send it to the control module.

[0019] The aforementioned control module is also used to adjust the display parameters of the aforementioned projection component based on the aforementioned environmental data.

[0020] Optionally, the above control module is also used for:

[0021] Determine the location of moviegoers based on the vehicle status described above;

[0022] The viewing seat angle of the viewer is determined based on the display component displaying the content to be projected and the position of the viewer. A seat adjustment signal including the viewing seat angle of the viewer is sent to the vehicle system so that the vehicle system adjusts the viewing seat angle of the viewer to the specified viewing seat angle based on the seat adjustment signal.

[0023] Optionally, when the display component for displaying the content to be projected is the second display component, the tilt angle of the second display component is adjusted based on the viewing seat angle of the viewer.

[0024] One embodiment of the above invention has the following advantages or beneficial effects: According to the vehicle projection system of the present invention, by setting a first display component located in front of the driver and a second display component located in other positions in the vehicle cabin, different display components are selected according to different vehicle states, so as to avoid affecting the driver's vision and distracting the driver's attention when the vehicle projection system is used.

[0025] Meanwhile, by switching between the first and second position states of the second display component, i.e., between the retracted state and the extended state, the second display component can be retracted when not in use, preventing the extended second display component from affecting the safety of the occupants, saving space in the cabin, and improving the space utilization of the cabin.

[0026] By adjusting the angle of the viewer's seat to the viewing seat angle, and adjusting the tilt angle of the second display component based on the viewing seat angle, the viewer's comfort during the movie viewing experience is enhanced, and the user experience is improved.

[0027] The further effects of the aforementioned unconventional alternative methods will be explained below in conjunction with specific implementation methods. Attached Figure Description

[0047] The display components of a vehicle-mounted projector are typically positioned in a location visible to all occupants, ensuring that everyone can view the projected content. However, using a projector while the vehicle is in motion can distract the driver and compromise driving safety.

[0048] If the display component is placed in a location that is not visible to the driver but is visible to other passengers, the driver will not be able to view the content to be projected while the vehicle is not moving.

[0049] In conclusion, existing in-vehicle projection systems cannot meet the entertainment needs of all occupants while ensuring driving safety, and the user experience during movie viewing still needs improvement.

[0050] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0051] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.

[0052] Figure 1 This is a schematic diagram of the main structure of an in-vehicle projection system according to an embodiment of the present invention. Figure 1 As shown, the vehicle projection system of this embodiment mainly includes: a first display component 101, a second display component 102, a projection component 103, a detection component 104, and a control module 105.

[0053] The first display component 101 is located in front of the driver.

[0054] In one optional embodiment, the first display component 101 may be disposed on the windshield in front of the driver, or on the interior roof 200 in front of the driver, or in other locations that enable all passengers in the vehicle to watch the movie, so that the first display component 101 can meet the viewing needs of all people in the vehicle when in use.

[0055] When installed on the windshield in front of the driver, the first display component 101 can be obtained by setting a transparent display film in the windshield, attaching a transparent display film to the surface of the windshield, or coating a transparent coating that does not obstruct the driver's view. Alternatively, a specially treated transparent display screen can be used as the vehicle's windshield, allowing the windshield to function as the first display component 101. This special treatment may involve coating the transparent display screen to give it the properties of a windshield, making it suitable for use as an automotive windshield. In this case, when the first display component 101 is not in use, the windshield is transparent and does not obstruct the driver's view; when the first display component 101 is in use, the content to be projected can be displayed on the windshield.

[0056] When installed on the interior headliner 200 in front of the driver, the first display assembly 101 may include a display screen 1021, a projection screen 1022, or a flexible screen. Further, the first display assembly 101 may include a foldable display screen 1021, a rollable projection screen 1022, or a rollable flexible screen, but is not limited thereto.

[0057] The second display component 102 is disposed in other locations in the vehicle cabin besides the location of the first display component 101, including but not limited to the interior ceiling 200, the rear windshield of the vehicle, other windows of the vehicle, or the side of the front seat back facing the rear passengers, so that the second display component 102 can meet the viewing needs of all people in the vehicle except the driver when in use.

[0058] Preferably, the second display component 102 can be positioned to at least meet the viewing needs of rear passengers in the vehicle. More preferably, the second display component 102 is located in the interior headliner 200.

[0059] When installed on the interior headliner 200 of a vehicle, the second display assembly 102 may include a display screen 1021, a projection screen 1022, or a flexible screen. Further, as shown in Figures 2(a)-6(c), the second display assembly 102 may include a foldable display screen 1021, a rollable projection screen 1022, or a rollable flexible screen, but is not limited thereto.

[0060] When the second display component 102 includes a foldable display screen 1021, the display screen 1021 itself can be folded or can be folded by other components. For example, as shown in Figures 2(a)-2(c), the second display component 102 may also include a rotating component 1023. The rotating component 1023 is rotatably disposed on the vehicle interior roof 200, and one end of the display screen 1021 is fixedly connected to the rotating component 1023. Rotation of the rotating component 1023 causes the display screen 1021 to be stored in the vehicle interior roof 200 or extended into the vehicle cabin space.

[0061] As shown in Figures 3(a)-3(c), when the second display component 102 includes a rollable projection screen 1022 or a flexible screen, it may also include a rotating component 1024. The rotating component 1024 is rotatably disposed on the interior ceiling 200 of the vehicle. One side of the projection screen 1022 or the flexible screen is fixedly connected to the rotating component 1024. The rotating component 1024 drives the projection screen 1022 or the flexible screen to be stored in the interior ceiling 200 of the vehicle or to extend into the interior space of the vehicle.

[0062] The projection component 103 is used to project content onto the first display component 101 or the second display component 102, so that the first display component 101 or the second display component 102 displays the content to be projected. The projection component 103 includes at least a projector, which can be set at any location in the vehicle cabin where the content to be projected can be completely projected onto the first display component 101 and the second display component 102, such as the interior ceiling 200 of the vehicle.

[0063] Understandably, since the first display component 101 and the second display component 102 are positioned differently, the projection component 103 should have an autofocus function to enhance the display effect of the content to be projected when different display components are selected to display the content to be projected. Specifically, when the content to be projected is projected onto the first display component 101, the projection component 103 can automatically focus on the first display component 101 in front of the driver; when the content to be projected is projected onto the second display component 102, the projection component 103 can automatically focus on the second display component 102, thereby achieving a better projection effect and improving the viewing experience of the audience.

[0064] Furthermore, to ensure good projection results, the projection angle, projection position, projector position, and display parameters of the projection component 103 can all be adjusted based on actual conditions. For example, during projection, when switching from the first display component 101 to the second display component 102, the projection angle and position of the projection component 103 can be adaptively adjusted due to the different positions and tilt angles of the two display components. As another example, when the first display component 101 is positioned on the windshield in front of the driver, the content projected onto the first display component 101 by the projection component 103 will be skewed and distorted because the windshield is tilted. Therefore, the projection angle and projector position can be adjusted to correct the skewed and distorted content, allowing viewers to see undistorted and unskewed projection content.

[0065] If the position of the projector in the projection assembly 103 is adjustable, the projection assembly 103 may also include a rotating telescopic component. For example, one end of the rotating telescopic component is disposed on the interior roof 200 of the vehicle, and the other end is connected to the projector. When the content to be projected is being calibrated, the projector can be adjusted in position by the rotation of the telescopic component.

[0066] The detection component 104 is used to detect the vehicle status. The vehicle status is used to indicate whether it is suitable for all passengers to watch the movie, including the first vehicle status and the second vehicle status.

[0067] Specifically, after the vehicle's infotainment system is started, the first vehicle state is characterized by the vehicle speed being less than a preset speed threshold, the gear being in parking mode, or the driving mode indicating the vehicle is in assisted driving mode, and the projection component 103 is performing projection. In the first vehicle state, the driver needs to be prepared to intervene in driving operations at any time, or only needs to perform a few simple driving operations, or does not need to operate the vehicle at all. At this time, the driver can watch the movie without affecting normal driving. Therefore, the first vehicle state can indicate that it is suitable for all passengers to watch the movie. The second vehicle state is characterized by the vehicle speed being greater than a preset speed threshold, the gear being in non-parking mode, and / or the driving mode indicating the vehicle is in non-assisted driving mode, and the projection component 103 is performing projection. In the second vehicle state, the vehicle is entirely driven by the driver, requiring the driver to operate the vehicle. At this time, in order to avoid the content to be projected distracting the driver's attention or affecting the driver's vision, the second vehicle state can indicate that it is not suitable for all passengers to watch the movie. As an example, the preset speed threshold can be set to 0 km / h.

[0068] The control module 105 is used to control the projection component 103 to project the content to be projected onto the first display component 101 in response to the vehicle state being a first vehicle state, and to control the projection component 103 to project the content to be projected onto the second display component 102 in response to the vehicle state being a second vehicle state.

[0069] Specifically, when the vehicle is in the first vehicle state, indicating that it is suitable for all passengers to watch the movie, the control module 105 can control the projection component 103 to automatically focus on the first display component 101 to project the content to be projected onto the first display component 101, so that all people in the vehicle can watch the content to be projected through the first display component 101. When the vehicle is in the second vehicle state, indicating that it is not suitable for all passengers to watch the movie, in order to ensure driving safety, the control module 105 can control the projection component 103 to automatically focus on the second display component 102 to project the content to be projected onto the second display component 102. Other people in the vehicle, except the driver, can watch the content to be projected through the second display component 102. Since the second display component 102 is located in the cabin in a position other than the location of the first display component 101, i.e., in front of the driver, the problem of the content to be projected affecting the driver's line of sight or distracting the driver's attention is avoided.

[0070] In addition, the control module 105 can also connect to the vehicle's infotainment system to acquire data such as the content to be projected. In this case, the control module 105 can connect to the vehicle's infotainment system via wired or wireless means to acquire the content to be projected. For example, the control module 105 can connect to the vehicle's infotainment system via a bus or via a wireless local area network.

[0071] In one optional embodiment, the second display component 102 has a first position state and a second position state; when the vehicle state is the first vehicle state, the second display component 102 is in the first position state, and when the vehicle state is the second vehicle state, the second display component 102 is in the second position state.

[0072] Furthermore, the first position state is a retracted state, and the second position state is an extended state. Specifically, the first position state is when the second display component 102 is retracted in a location within the vehicle cabin other than in front of the driver, and the second position state is when the second display component 102 extends into the space within the vehicle cabin.

[0073] Specifically, when the vehicle is in the first vehicle state, the driver does not need to operate the vehicle. The control module 105 can control the projection component 103 to project the content to be projected onto the first display component 101 located in front of the driver, so that all people in the vehicle can view the content to be projected through the first display component 101. At this time, there is no need to use the second display component 102. Therefore, when not in use, the second display component 102 is in the first position state, i.e., the retracted state, and is stored in the interior roof 200, thereby avoiding the second display component 102 from blocking the content to be projected and from bumping into people in the vehicle. At the same time, it can save space in the vehicle cabin and improve the utilization rate of the vehicle cabin space. When the vehicle is in the second vehicle state, the driver needs to perform driving operations. The control module 105 can control the projection component 103 to project the content to be projected onto the second display component 102 located in other positions in the vehicle cabin, so that other people in the vehicle except the driver can view the content to be projected through the second display component 102. At this time, the second display component 102 in use is in the second position state, i.e., the unfolded state, so that the projection component 103 can project the content to be projected onto the second display component 102.

[0074] In an optional embodiment, the control module 105 is further configured to control the second display component 102 to switch from the first position state to the second position state in response to the vehicle state being the second vehicle state.

[0075] As shown in Figures 2(a)-2(b), 3(a)-3(b), or 4(a)-4(b), if the detection component 104 detects that the vehicle state has switched from another state to the second vehicle state, the control module 105 can respond as follows based on the signal of switching to the second vehicle state: control the second display component 102 to switch from the first position state to the second position state, that is, control the second display component 102 to change from the state of being stored in a position other than in front of the driver in the vehicle cabin to the state of being extended in the space of the vehicle cabin.

[0076] In one possible implementation, when the second display component 102 is disposed on the interior roof 200, the second display component 102 in the first position state can be accommodated in the groove 201 or the cavity 301 between the interior roof 200 and the roof sheet 300 above the opening by providing a groove 201 or an opening in the interior roof 200.

[0077] As shown in Figures 2(a)-3(c), a groove 201 may be provided at the position where the second display component 102 is located in the interior roof 200 of the vehicle to accommodate the folded or rolled-up second display component 102, so as to prevent the second display component 102 from protruding from the interior roof 200 during vehicle use and causing bumping injury to the occupants of the vehicle.

[0078] As shown in Figure 2(a), when the second display component 102 includes a foldable display screen 1021, when the detection component 104 detects that the vehicle state is the first vehicle state, the control module 105 controls the display screen 1021 to fold itself into the groove 201 of the interior roof 200, so that the second display component 102 is in the first position state; as shown in Figure 2(b), when the detection component 104 detects that the vehicle state has switched to the second vehicle state, it controls the display screen 1021 to extend itself out of the groove 201 and extend into the cabin space, so that the second display component 102 is in the second position state. Alternatively, when the detection component 104 detects that the vehicle status is a first vehicle status, the control module 105 controls the rotating component 1023 of the second display component 102 to fold the display screen 1021 into the groove 201 of the interior roof 200, and the second display component 102 is in a first position state; when the detection component 104 detects that the vehicle status is a second vehicle status, the control module 105 controls the rotating component 1023 of the second display component 102 to rotate, so that the display screen 1021 rotates out of the groove 201 and extends into the cabin space, and the second display component 102 is in a second position state. Similarly, as shown in Figures 3(a)-3(c), when the second display component 102 includes a rollable projection screen 1022 or a rollable flexible screen, the control module 105 controls the rotation of the rotating component 1024 to roll the projection screen 1022 or the flexible screen into the groove 201 or extend it into the cabin space, so that the second display component 102 is in a first position state or a second position state.

[0079] As shown in Figures 5(a)-6(c), the interior headliner 200 may have an opening so that the second display component 102 can be received in the cavity 301 between the interior headliner 200 and the roof sheet 300 through the opening, thereby hiding it in the first position and saving space in the vehicle cabin. The first position of the second display component 102 in the cavity 301 and the second position in the vehicle cabin space are similar to those when the interior headliner 200 has a recess 201, and will not be described again here.

[0080] It should be noted that when the first display component 101 is disposed on the interior roof 200 in front of the driver, as described in the above embodiments, other grooves for accommodating the first display component 101 or openings for the first display component 101 can be provided on the interior roof 200 so that the first display component 101 can be accommodated in the above-mentioned other grooves or in the cavity between the interior roof 200 and the roof sheet 300 when not in use.

[0081] In an optional embodiment, the detection component 104 is further configured to acquire environmental data and send it to the control module 105; the control module 105 is further configured to adjust the display parameters of the projection component 103 based on the environmental data.

[0082] Environmental data may include ambient brightness, and display parameters may include projection brightness, contrast, etc. For example, the detection component 104 may include a built-in optical sensor to acquire ambient brightness after the vehicle projection system is started, and send it to the control module 105. The control module 105 can adaptively adjust the projection brightness and contrast of the projection component 103 according to the ambient brightness to display the content to be projected more clearly to the viewers and improve the viewing experience.

[0083] In an optional embodiment, the control module 105 is further configured to: determine the position of the movie viewer based on the vehicle status; determine the viewing seat angle of the movie viewer based on the display component displaying the content to be projected and the position of the movie viewer; and send a seat adjustment signal including the viewing seat angle of the movie viewer to the vehicle system, so that the vehicle system adjusts the viewing seat angle of the movie viewer to the viewing seat angle based on the seat adjustment signal.

[0084] Specifically, vehicle status can also include the seating positions of all occupants and user input information. It's understandable that user input information is selectively entered by occupants based on their own needs; that is, if occupants don't have specific needs, they don't need to input it, and therefore the vehicle status doesn't include user input information. Conversely, if occupants have specific needs and can input it, then the vehicle status includes user input information.

[0085] Furthermore, several questions with multiple options are pre-set. When the in-vehicle projection system is started, the user input information is determined by receiving the user's selection results of the above questions. Alternatively, the user can input special requirements on their own, and the user input information is determined by semantic recognition of the special requirements entered by the user.

[0086] After the detection component 104 acquires data such as the seating positions of all occupants inside the vehicle, user input information, and whether the vehicle is currently in the first or second vehicle state, it can send this data to the control module 105. Based on this data, the control module 105 determines the positions of the viewers inside the vehicle and the display component for displaying the content to be projected. As an example, when all occupants in the vehicle are seated in the driver's seat, front passenger seat, and left rear seat, and the vehicle is in a first vehicle state, the driver does not need to perform driving operations, and the viewers can include all occupants. Therefore, the control module 105 can determine that the viewers' positions include the seat positions of all occupants, and the display component for displaying the content to be projected is the first display component 101. When all occupants in the vehicle are seated in the driver's seat, left rear seat, and right rear seat, and the vehicle is in a second vehicle state, the driver needs to perform driving operations. The control module 105 can determine that the viewers' positions include the left rear seat and the right rear seat, and the display component for displaying the content to be projected is the second display component 102. When all occupants in the vehicle are seated in the driver's seat, left rear seat, and right rear seat, and the user input indicates that the viewers are in the left rear seat, and the vehicle is in a second vehicle state, the driver needs to perform driving operations. The control module 105 can directly determine that the viewers' positions are in the left rear seat based on the user input, and the display component for displaying the content to be projected is the second display component 102.

[0087] As shown in Figures 2(c), 3(c), 4(c), 5(c), or 6(c), after determining the position of the viewer, the control module 105 can determine the viewing seat angle of the viewer based on the display component displaying the content to be projected and the viewer's position. For example, when the display component displaying the content to be projected is the second display component 102 and the viewer's position is the left rear seat, the left rear seat angle can be 130°; when the display component displaying the content to be projected is the first display component 101 and the viewer's position is the right rear seat, the left and right seat angles can be 120°.

[0088] Then, the control module 105 can send a seat adjustment signal, including the viewing seat angle of the aforementioned moviegoer, to the vehicle system. After receiving the seat adjustment signal, the vehicle system adjusts the viewing seat angle of the moviegoer to the viewing seat angle of the aforementioned moviegoer, thereby improving the comfort of the moviegoer when watching the movie.

[0089] Furthermore, when the display component for displaying the content to be projected is the second display component 102, the tilt angle of the second display component 102 is adjusted based on the viewing seat angle of the viewers.

[0090] To improve the viewing experience, the tilt angle of the second display component 102 can be adjusted under the control of the control module 105, making it easier for viewers to see the projected content. The relationship between the tilt angle and the viewing seat angle can be predetermined, allowing the tilt angle of the second display component 102 to be determined based on this relationship after the viewing seat angle is obtained. Accordingly, as shown in Figure 4(c), after adjusting the tilt angle of the second display component 102, the projection component 103 automatically focuses on the tilted second display component 102. Simultaneously, the projected content can be corrected by adjusting the projection angle and projector position, ensuring that viewers see projected content without skew or distortion.

[0091] When the second display component 102 includes a foldable display screen 1021, the control module 105 can control the rotating component 1023 or the display screen 1021 itself to adjust the tilt angle; when the second display component 102 includes a rollable projection screen 1022 or a flexible screen, the second display component 102 may also include a stretching component 1025, the stretching component 1025 includes a telescopic connecting part 10251 and a fixing part 10252, the fixing part 10252 is fixed to the interior roof 200, the telescopic connecting part 10251 can connect the side of the projection screen 1022 or the flexible screen away from the rotating component 1024, and the tilt angle of the projection screen 1022 or the flexible screen can be adjusted by controlling the length of the telescopic connecting part 10251.

[0092] Additionally, it is understood that when the first display component 101 is mounted on the interior ceiling 200 in front of the driver, and the display component displaying the content to be projected is the aforementioned first display component 101, the tilt angle of the aforementioned first display component 101 can be adjusted based on the viewing seat angle of the aforementioned moviegoer.

[0093] According to an embodiment of the present invention, the vehicle projection system provides a first display component 101 located in front of the driver and a second display component 102 located in other positions within the vehicle cabin. When the vehicle is in different vehicle states, different display components are selected accordingly to avoid affecting the driver's line of sight and distracting the driver's attention when the vehicle projection system is in use.

[0094] Meanwhile, by switching the second display component 102 between the first position state and the second position state, that is, between the retracted state and the extended state, the second display component 102 can be retracted when not in use, preventing the extended second display component 102 from affecting the safety of the people in the vehicle, saving space in the vehicle cabin, and improving the space utilization rate of the vehicle cabin.

[0095] By adjusting the angle of the viewer's seat to the viewing seat angle, and adjusting the tilt angle of the second display component 102 based on the viewing seat angle, the viewer's comfort during the movie viewing experience is enhanced, and the user experience during the movie viewing experience is improved.
