Description

Human-computer interaction method, system and vehicle for passenger seat sunshade screen Technical Field

[0001] The present invention relates to the field of vehicle intelligent control technology, and in particular to a human-computer interaction method, system and vehicle for a passenger seat sunshade screen. Background Art

[0002] As vehicles become increasingly intelligent, market demands for these features are becoming increasingly diverse. In this context, user demands for in-car displays are no longer limited to drivers, but are now extending to passengers as well. In-car displays have evolved from their original purpose of driving assistance tools to consumer electronics products that cater to the entertainment needs of diverse users.

[0003] Currently, passenger sun visors in the automotive industry have limited functionality and poor human-machine interaction. Therefore, satisfying passenger entertainment needs has become a key goal, requiring manufacturers to prioritize the passenger sun visor's user experience.

[0004] For example, the sun visor control method, device and vehicle disclosed in patent document CN112572110A mentions a solution that allows the driver to automatically adjust the sun visor while driving. The solution focuses on the automatic shading control solution of the sun visor, which captures the ambient light intensity and the direction of the vehicle head through an external camera to automatically control the angle of the sun visor. However, the control solution mentioned in the patent is limited to solving the shading problem and cannot solve the passengers' entertainment needs such as viewing comfort.

[0005] Another example is patent document CN112977015A, which discloses a sunshade structure, vehicle, and display control method. This method proposes replacing the existing sun visor design with a display module, replacing the sunshade function. The display module also displays reserved data information, primarily for phone number reservations, making it easier to quickly find the owner's contact information when parking. This sunshade display device only has the functions of shading and displaying reserved information, such as numbers, for people outside the vehicle. The reserved information display function is intended for people outside the vehicle, and the entire sunshade display device suffers from a single function and insufficient automation.

[0006] Therefore, it is necessary to develop a human-computer interaction method, system and vehicle for a passenger car sunshade screen.

DETAILED DESCRIPTION

[0043] The following will describe the implementation of the technical solution of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for the purpose of illustrating the present invention and are not intended to limit the scope of protection of the present invention.

[0044] As shown in Figures 1 and 2, in this embodiment, a human-computer interaction system for a passenger sun visor includes a passenger sun visor, a camera, an angle detection module, and a controller. The passenger sun visor is used to block light and play video information. The passenger sun visor can be rotatably set on the ceiling of the passenger compartment of the vehicle. The camera is used to track the position information of the passenger seat occupant in real time and transmit the position information of the passenger seat occupant to the controller. The angle detection module is used to collect the rotation angle of the passenger seat visor, and the controller is used to control the rotation angle of the passenger seat visor and audio and video playback, as well as dynamically adjust the position of the passenger seat visor based on the position information of the passenger seat occupant and the rotation angle of the passenger seat. The controller is connected to the passenger seat visor, the angle detection module, and the camera respectively.

[0045] In this embodiment, the camera is positioned at the center of the passenger sunshade's visible area. The passenger sunshade also features a TV mode. The controller is further configured to, upon detecting that the passenger sunshade is open and in TV mode, control the camera to track the passenger's eye position in real time, ensuring accurate tracking of the passenger's eye position. If desired, the camera can also be enabled in selfie mode, replacing the vanity mirror function.

[0046] As shown in Figure 2, in this embodiment, the controller is further configured to: calculate the deviation between the virtual line between the passenger's eyeball and the camera and the normal direction of the passenger's sun visor, and compare the deviation with a preset deviation value (for example, 5°). If the deviation is less than or equal to the preset deviation value, the current flip angle of the passenger's sun visor is maintained; if the deviation is greater than the preset deviation value, the target angle position of the passenger's sun visor is calculated based on the passenger's eyeball position and the rotation angle information of the passenger's sun visor, and the passenger's sun visor is controlled to rotate to the target angle position, even if the deviation between the virtual line between the user's eyeball and the camera and the normal direction of the screen is less than or equal to 5°.

[0047] As shown in FIG6 , in this embodiment, a human-computer interaction system for a passenger sunshade includes a light sensor for monitoring ambient light intensity, which is connected to a controller. The controller is further configured to automatically control the opening and closing of the passenger sunshade based on ambient light intensity when the passenger sunshade is not in TV mode. When the passenger sunshade is closed, the passenger sunshade is almost parallel to the vehicle roof, reducing the space occupied by the vehicle interior. When the passenger sunshade is open, the passenger sunshade forms a certain angle with the vehicle roof to achieve sunshade. The passenger sunshade alone provides both sunshade and audio / video display functions, achieving structural integration and maximizing functionality. This effectively avoids glare from mirror displays and reduces direct radiation from strong external light, enhancing the user experience. The system can automatically achieve sunshade function in strong light environments, making it more user-friendly and intelligent.

[0048] As shown in FIG6 , in this embodiment, a human-computer interaction system for a passenger sunshade further includes a door assembly for providing feedback on the door status to a controller, the door assembly being connected to the controller. The passenger sunshade is also configured with a courtesy mode. The controller is further configured to: upon detecting that the passenger sunshade is in the deployed state, control the courtesy mode of the passenger sunshade to be in an on-standby state; upon detecting that the vehicle door is opened and recognizing that the passenger seat passenger intends to exit the vehicle or that a passenger intends to enter the passenger seat, activate the courtesy mode of the passenger sunshade and control the passenger seat passenger sunshade to move toward the front windshield to a courtesy position; and, when the passenger seat sunshade is in the courtesy mode, in response to detecting that the passenger seat door is closed, control the passenger seat passenger sunshade to move to a position prior to activation of the courtesy mode, exit the courtesy mode, and enter the on-standby state of the courtesy mode. This provides a courtesy function to prevent the passenger seat passenger from bumping into the passenger seat sunshade when entering or exiting the vehicle.

[0049] As shown in Figure 6, in this embodiment, a human-machine interaction system for a passenger sunshade includes a TV mode activation module configured to issue a command to activate TV mode. The TV mode activation module establishes a communication connection with a controller. The controller is further configured to, upon detecting that the passenger sunshade's TV mode is inactive, control the passenger seat to move to a memorized seat position Ps1 for TV mode, control the passenger sunshade to rotate to a memorized position Pr1 for TV mode, and control the passenger sunshade to enter TV mode. The seat position Ps1 includes the seat back angle and the seat's fore-aft position. In other words, when a user activates the TV mode function, the vehicle automatically controls the movement of the passenger seat and the sunshade simultaneously, aligning the seat position with the sunshade's deployment angle, allowing the passenger to rest in a comfortable position while viewing the sunshade. The adaptive positions of the passenger sunshade and seat can be customized and memorized based on user needs. This approach improves passenger comfort.

[0050] As shown in Figure 6, in this embodiment, the TV mode activation module is a passenger sunshade TV mode switch, which establishes a communication connection with a controller. The controller is further configured to, when the passenger sunshade's TV mode is inactive, issue a TV mode activation command in response to detecting that the TV mode activation button has been triggered. In other words, the passenger sunshade's TV mode can be activated by triggering the passenger sunshade's TV mode switch.

[0051] As shown in Figure 6, in this embodiment, the TV mode activation module can also be a voice recognition module, which establishes a communication connection with the controller. The controller is also configured to: when the TV mode of the passenger sunshade is not activated, in response to receiving a voice command to enter the TV mode of the passenger sunshade, issue an activation TV mode command; that is, the TV mode of the passenger sunshade can be activated by voice. For example: when the user says to turn on the TV mode, the vehicle system will actively ask the user "Do you want to turn on the TV mode?" through voice. If the response "OK" is detected, the passenger sunshade will be controlled to move to the TV mode position to facilitate the user to watch the video. If other responses are detected, the vehicle will not perform any operation.

[0052] As shown in Figure 6, in this embodiment, the passenger seat includes a seat and a first control unit that controls the seatback angle and fore-aft position. After entering the vehicle, the user can adjust the seat to their preferences. The first control unit establishes a communication connection with the controller. The controller is further configured to, when the TV mode of the passenger sunshade is inactive, issue a confirmation message indicating whether to activate the TV mode of the passenger sunshade in response to detecting movement of the passenger seat to a preset angle, and to issue a command to activate the TV mode upon receiving the confirmation message indicating whether to activate the TV mode of the passenger sunshade. The TV mode of the passenger sunshade can be activated by adjusting the seat.

[0053] In this embodiment, as shown in Figures 7 to 13, the passenger sunshade includes a sunshade display module and a second control unit connected to the sunshade display module. The sunshade display module includes a module base 1, a rotating mechanism 2, a display screen 3, and a module housing 4. The upper portion of the module base 1 is provided with a mounting structure 11 for connecting to the front roof crossbar 6 of the vehicle. The lower portion of the module base 1 is connected to the module housing 4, forming a cavity therebetween. The rotating mechanism 2 includes a fixing assembly, an electric drive assembly, and a mechanism housing 27. The fixing assembly is fixed within the cavity, and the electric drive assembly is connected to the fixing assembly, capable of driving the mechanism housing 27 to rotate. The module housing 4 is provided with a clearance groove 41 corresponding to the mechanism housing 27. The mechanism housing 27 extends from the clearance groove 41, and one end of the display screen 3 is connected to the mechanism housing 27. The mounting structure 11 comprises two locating pins and four bolt connection holes.

[0054] The module base 1 is connected to the front roof beam 6 of the vehicle via a mounting structure 11, allowing the vehicle sunshade device to be installed above and in front of the passenger seat. When the vehicle sunshade device is not in use, the display screen 3 is horizontally positioned, facing the module housing 4. When the passenger needs sunshade protection, such as when driving in strong sunlight, the electric drive assembly can drive the mechanism housing 27 to rotate, which in turn drives the display screen 3, causing the display screen 3 to rotate toward the front windshield 7 until it reaches an angle that blocks sunlight and then hovers. This reduces sunlight radiation and prevents strong light from directly hitting the passenger, improving the passenger's comfort. When the passenger needs audio and video entertainment, the electric drive assembly can drive the mechanism housing 27 to rotate, which in turn drives the display screen 3, causing the display screen 3 to rotate toward the front windshield 7 until it reaches an angle suitable for viewing and then hovers. This meets the passenger's audio and video entertainment needs and enhances the functionality and practicality of the vehicle sunshade device.

[0055] In this embodiment, the fixing assembly includes a main pin seat 21 and a secondary pin seat 22 respectively provided on the left and right sides of the mechanism housing 27. The main pin seat 21 and the secondary pin seat 22 are connected to the mechanism housing 27 by screws.

[0056] In this embodiment, the electric drive assembly includes a motor 23, a gearbox 24, and a main shaft 25, which are sequentially connected in a transmission manner. The end of the main shaft 25, which is away from the gearbox 24, is fixedly connected to the kingpin seat 21. The motor 23 and gearbox 24 are both fixedly connected to the inner wall of the mechanism housing 27. The interior of the mechanism housing 27 is hollow and can be used to accommodate the motor 23, gearbox 24, and damper 26. The gearbox 24 can convert the high-speed and low-torque output of the motor 23 into low-speed and high-torque. When the motor 23 is working, the power of the motor 23 is transmitted to the gearbox 24 and the main shaft 25 in turn, so that the main shaft 25 rotates relative to the motor 23 and the gearbox 24. However, since the main shaft 25 is fixedly connected to the kingpin seat 21, the main shaft 25 cannot rotate. Therefore, when the motor 23 is working, the motor 23 and the gearbox 24 will rotate relative to the main shaft 25 and the kingpin seat 21. The motor 23 and the gearbox 24 are both fixedly connected to the mechanism housing 27, so when the motor 23 is working, it can drive the mechanism housing 27 to rotate relative to the kingpin seat 21, thereby realizing the movement of the display screen 3 relative to the kingpin seat 21 and the module housing 4.

[0057] In this embodiment, the electric drive assembly further includes a damper 26, which is used to increase the friction force when the mechanism housing 27 and the main shaft 25 rotate relative to each other. Increasing the friction force when the mechanism housing 27 and the main shaft 25 rotate relative to each other can enable the mechanism housing 27 to rotate smoothly.

[0058] In this embodiment, the mechanism housing 27 includes a left sleeve 271, a middle sleeve 272, and a right sleeve 273, which are connected in sequence. A left rotating shaft is provided at the left end of the left sleeve 271. The main mounting hole is provided in the main pin seat 21, and the left rotating shaft is rotatably connected to the main mounting hole. A right rotating shaft 2731 is provided at the right end of the right sleeve 273. The secondary mounting hole 222 is provided in the secondary pin seat 22, and the right rotating shaft 2731 is rotatably connected to the secondary mounting hole 222. This structural arrangement ensures that the mechanism housing 27 can rotate relative to the fixed assembly.

[0059] In this embodiment, a rotation limiter 2732 is provided on the right rotating shaft 2731, and a rotation limiter slot 221 is provided in the secondary pin holder 22 for engaging with the rotation limiter 2732. The rotation limiter 2732 is inserted into the rotation limiter slot 221 to limit the right rotation angle. During the process of rotating the rotation limiter 2732 from abutting the leading end of the rotation limiter slot 221 to abutting the trailing end of the rotation limiter slot 221, the right rotating shaft 2731 rotates 170°.

[0060] In this embodiment, the left sleeve 271 and the right sleeve 273 are both provided with mounting ears 274 for connecting to the display screen 3. After the display screen 3 is connected to the two mounting ears 274, it can rotate synchronously with the left sleeve 271 and the right sleeve 273.

[0061] In this embodiment, the electric drive component also includes a circuit board 28 arranged in the cavity, and the circuit board 28 is connected to the module housing 4; a wiring harness through-hole 2733 is provided inside the right rotating shaft 2731, and the wiring harness of the circuit board 28 passes through the auxiliary mounting hole 222 and the wiring harness through-hole 2733 and is connected to the motor 23.

[0062] In this embodiment, a decorative blocking plate 5 is further provided in the cavity, and the decorative blocking plate 5 is connected to the module base 1. The decorative blocking plate 5 can be used to shield the bolts used to connect the module base 1 and the front roof beam 6 of the vehicle.

[0063] In this embodiment, the display screen 3 is provided with a mirror reflective film 31. When the display screen 3 is in the on state, the mirror reflective film 31 is able to transmit light normally and does not affect the front passenger's viewing. When the front passenger needs to use a vanity mirror, the electric drive assembly can drive the mechanism housing 27 to rotate, which in turn drives the display screen 3, so that the display screen 3 rotates toward the front windshield 7 until it rotates to an angle facing the front passenger, and then hovers. The display screen 3 is in the off state. At this time, the display screen 3 with the mirror reflective film 31 can be used as a vanity mirror, meeting the front passenger's vanity mirror needs.

[0064] As shown in FIG6 , in this embodiment, the angle detection module uses an angle sensor, which is set at the rotation axis of the passenger sunshade. It can accurately record the real-time rotation angle of the passenger sunshade and transmit the angle information back to the controller in real time.

[0065] As shown in FIG1 , FIG3 , FIG4 and FIG5 , in this embodiment, a human-computer interaction method for a passenger car sun visor is provided, which uses the human-computer interaction system for the passenger car sun visor as described in this embodiment, and the method includes the following steps:

[0066] (1) When it is detected that the TV mode of the passenger sunshade is not activated, in response to receiving an activation instruction for the TV mode, the passenger seat is controlled to move to the seat position Ps1 memorized in the TV mode, the passenger sunshade is controlled to rotate to the passenger sunshade position Pr1 memorized in the TV mode, and the passenger sunshade is controlled to enter the TV mode; wherein, the seat position Ps1 includes the seat back angle and the position of the seat in the front-to-back direction. Before the passenger sunshade rotates to the passenger sunshade position Pr1 memorized in the TV mode, if it is detected that the passenger sunshade stops moving (for example, the passenger sunshade adjustment switch is pressed and the passenger sunshade stops moving), it indicates that the entry into the TV mode is abnormal, and the TV mode of the passenger sunshade is exited. Before the passenger seat moves to the seat position Ps1 memorized in the TV mode, if it is detected that the passenger seat stops moving (for example, the passenger seat adjustment switch is pressed and the passenger seat stops moving), it indicates that the entry into the TV mode is abnormal, and the TV mode of the passenger sunshade is exited.

[0067] (2) When the passenger sunshade is in TV mode, the position information of the passenger seat occupant (e.g., the eye information of the passenger seat occupant) and the rotation angle of the passenger sunshade are obtained; and the position of the passenger sunshade is dynamically adjusted based on the eye position information and the rotation angle information of the passenger sunshade.

[0068] (3) When the passenger sunshade is not in TV mode, the external ambient light intensity is monitored and the opening and closing of the passenger sunshade is automatically controlled based on the external ambient light intensity.

[0069] (4) When it is detected that the passenger sunshade is in the unfolded state (for example, in the TV mode or in the sunshade mode), the courtesy mode of the passenger sunshade is controlled to be in the on-standby state, and when it is detected that the vehicle door is opened and it is identified that the passenger on the passenger side intends to get off the vehicle or that a passenger intends to enter the passenger side, the courtesy mode of the passenger sunshade is activated, and the passenger sunshade is controlled to move toward the front windshield side to the courtesy position; and when the passenger sunshade is in the courtesy mode, in response to detecting that the passenger door is closed, the passenger sunshade is controlled to move to the position before the courtesy mode is activated, and the courtesy mode is exited, and the courtesy mode is entered into the on-standby state.

[0070] In this embodiment, a vehicle employs the human-machine interaction system for the passenger sunshade as described in this embodiment. The above embodiments are preferred implementations of the present invention, but the implementation of the present invention is not limited to these embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principles of the present invention shall be considered equivalent replacements and are included within the scope of protection of the present invention.
