The control instructions are instructions for adjusting the relative position between the display position of the display device 1 and the line of sight of the eyes of the occupants in the vehicle.

[0044] Among them, one end of the execution module 4 is connected to the control module 3, wherein the connection mode of the execution module 4 and the control module 3 may include but is not limited to linear connection, and the linear connection may include but is not limited to connection using the vehicle bus.

[0045] For the embodiments of the present disclosure, Figure 2 As shown, the execution module 4 of the vehicle-mounted tracking display system includes a motor 41 and a mechanical arm 42; the motor 41 is connected to the mechanical arm 42, and the mechanical arm 42 is connected to the display device 1, and the motor 41 is used to drive the mechanical arm 42 to drive the display device 1 to move, so that the display position change speed of the display device 1 is consistent with the line of sight movement speed.

The execution module 4 can drive the display device 1 to move along the three axes of X-axis, Y-axis and Z-axis, and can circle counterclockwise or clockwise along the X-axis, Y-axis and Z-axis. The execution module 4 also has a certain damping force, which is used to maintain the current state of the display device 1 under conditions where there is no control instruction.

[0046] For the embodiments of the present disclosure, Figure 1As shown, the control module 3 of the vehicle-mounted tracking and display system is connected to the vehicle-mounted system 6 through the vehicle-end interface 5. The vehicle-mounted system 6 is used to provide power to the control module 3 through the vehicle-end interface 5, and to send a trigger signal for triggering the working state of the vehicle-mounted tracking and display system to the control module 3 through the vehicle-end interface 5. The working state includes the power-on state, the running state, the standby state and the power-off state. Among them, there is a connector 51 inside the vehicle-end interface 5, which can be connected with the vehicle-mounted system 6 and the control module 3. The vehicle-end interface 5 can be used to transmit the vehicle's current, vehicle-mounted data, etc. It can be understood that the vehicle-end interface 5 can transmit a variety of objects, which are not limited in this disclosure; the vehicle-end interface 5 can include but is not limited to a universal serial bus (USB) interface, an on-board diagnostic system (OBD) interface, etc., which is not specifically limited. Among them, the on-board data may include but is not limited to audio data, video data, control data, etc. sent by the vehicle system 6. The vehicle-end interface 5 can be set at any position of the vehicle, including but not limited to below the main driver's center console, below the left side of the steering wheel, in the middle of the main driver's center console, the co-pilot position, etc., without specific limitation. The vehicle-end interface 5 is used to provide electrical connection and structural connection for the vehicle-mounted tracking and display system. When the control module 3 receives a trigger signal for indicating a power-on state, the control module 3 controls the entire vehicle-mounted tracking display system to power on; when the control module 3 receives a trigger signal for indicating a running state, the control module 3 controls the entire vehicle-mounted tracking display system to track the eye movements of the vehicle occupants, so that the screen display direction of the display device 1 is opposite to the line of sight of the vehicle occupants; when the control module 3 receives a trigger signal for indicating a standby state, the control module 3 controls the entire vehicle-mounted tracking display system to turn on, but does not track the eyes of the vehicle occupants; when the control module 3 receives a trigger signal for indicating a power-off state, the control module 3 controls the entire vehicle-mounted tracking display system to stop tracking the eyes of the vehicle occupants, and folds the vehicle-mounted tracking display system.

[0047] For the disclosed embodiment, the display device 1 of the vehicle-mounted tracking display system is connected to the vehicle-machine system 6 via the vehicle-end interface 5. The vehicle-machine system 6 is used to provide power to the display device 1 and send display data to the display device 1. The display data is data used to provide a screen display to the display device 1. The display data may include but is not limited to audio data, video data, control data, etc., and no specific limitation is made to this.

[0048] For the embodiments of the present disclosure, Figure 3As shown, the vehicle-mounted tracking display system also includes a key module 7, wherein the key module 7 can be set within the range where the driver does not need to deviate from the road line of sight and the hand can touch the vehicle-mounted tracking display system, for example, the display device 1, sensor module 2, control module 3, execution module 4 and vehicle-end interface 5 of the vehicle-mounted tracking display system can be set at any position, or other places of the vehicle-mounted tracking display system, without specific limitation, which can improve the safety of the occupants in the vehicle (such as the driver) during driving. The key module 7 can collect the key touch information of the occupants in the vehicle, and convert the key touch information into a trigger signal, and upload the trigger signal to the control module 3. Correspondingly, the control module 3 can receive the trigger signal uploaded by the key module 7. Among them, the key module 7 is used to send a trigger signal to the control module 3, and the trigger signal is used to trigger the working state of the vehicle-mounted tracking display system. Among them, the key touch information may include the key type, touch frequency, number of touches, etc. of the touch, different key touch information may pre-set different trigger signals, and the trigger signal may include a first trigger signal, a second trigger signal, a third trigger signal and a fourth trigger signal, wherein the first trigger signal is used to trigger the working state of the vehicle tracking display system to be the power-on state, the second trigger signal is used to trigger the working state of the vehicle tracking display system to be the running state, the third trigger signal is used to trigger the working state of the vehicle tracking display system to be the standby state, and the fourth trigger signal is used to trigger the working state of the vehicle tracking display system to be the power-off state. The key module 7 may include but is not limited to a hardware key. In the embodiment of the present disclosure, the technical solution in the present disclosure is described by taking the key module 7 as a hardware key as an example, but it does not constitute a specific limitation on the technical solution in the present disclosure. For example, four hardware buttons are set on the steering wheel: button A, button B, button C and button D; it is preset that when the user touches button A, the button module 7 sends a first trigger signal to the control module 3 for triggering the working state of the vehicle tracking display system to be the power-on state; when the user touches button B, the button module 7 sends a second trigger signal to the control module 3 for triggering the working state of the vehicle tracking display system to be the running state; when the user touches button C, the button module 7 sends a third trigger signal to the control module 3 for triggering the working state of the vehicle tracking display system to be the standby state; when the user touches button D, the button module 7 sends a fourth trigger signal to the control module 3 for triggering the working state of the vehicle tracking display system to be the power-off state.

[0049] In addition, in actual applications, it is possible that the user does not actually want to upload the trigger signal, but accidentally touches the hardware button with his hand when moving his body. Therefore, in order to avoid misjudgment, as a preferred method, the button module 7 can be combined with the fingerprint recognition module. For example, the button in the button module 7 can be set as a fingerprint recognition button, and the target user fingerprint information is pre-set in the button module 7. When the user touches the button, the current user's fingerprint information can be collected at the same time, and the collected current user fingerprint information is further compared with the target user's fingerprint information for similarity. If the similarity is greater than a preset threshold (such as a preset threshold of 85%), the current user is judged to be a target user with the authority to send a trigger signal, and the button module 7 can upload a corresponding trigger signal according to the button touch information.

[0050] In a specific application scenario, the button module 7 can also be a virtual button. As a possible implementation method, the image recognition method can be used in conjunction with the projection lamp in the car. The projection lamp can project the projection image to any position in the car that does not block the driver's line of sight and can be touched by the driver's hand. For example, the display device 1, sensor module 2, control module 3, execution module 4 and vehicle-side interface 5 of the vehicle-mounted tracking display system can be set at any position, or other places of the vehicle-mounted tracking display system. There is no specific limitation on this, which can improve the safety of the occupants (such as the driver) in the vehicle during driving. The projection image can be one or more button images of the switching trigger signal. The image recognition method is used to identify the button image projected by the hand clicking the projection image downward, and the identified action is compared with the preset action. If the action is consistent, the control module 3 can receive the corresponding trigger signal generated by the image recognition module. Among them, the button shape and the brightness of the projection image can be set by the user, and can also be adjusted according to the current external environment of the vehicle.

[0051] In a specific application scenario, as a possible implementation method, the audio recognition module can also be used to collect trigger signals, so that the passengers in the car can automatically adjust the screen display direction of the display device 1 to be opposite to the line of sight of the passengers in the car without touching the button, thereby improving the riding experience of the passengers in the car. The audio recognition module can collect the user's voice audio, and can further identify whether the user's voice audio is consistent with the preset audio features and audio content corresponding to the trigger signal. If they are consistent, a trigger signal matching the voice audio can be sent to the control module 3. Accordingly, when the audio recognition module identifies whether the voice audio sent by the current user is consistent with the preset audio features, as a possible implementation method, the audio recognition module can calculate the similarity between the voice timbre sent by the current user and the preset target user's voice timbre. If the similarity is greater than a preset threshold (such as 85%), it is determined that the current user is a target user with the authority to send a trigger signal, and the control module 3 can receive the trigger signal generated by the user audio recognition module.

[0052] In a specific application scenario, as a possible implementation method, a trigger signal can also be sent using software. The touch-screen vehicle system 6 can be used to send a trigger signal for triggering the working status of the vehicle-mounted tracking display system to the control module 3 through the vehicle-side interface 5.

[0053] For the embodiments of the present disclosure, Figure 4 As shown, the control module 3 includes a timer 31; the timer 31 is used to start when the vehicle-mounted tracking display system is in the power-on state, and record the accumulated time when the vehicle-mounted tracking display system changes from the power-on state to the running state.

[0054] In specific application scenarios, such as Figure 2 As shown, after the control module 3 receives the first trigger signal (trigger signal 1), the vehicle tracking display system (display system) is powered on, the timer 31 in the control module 3 is started, and the vehicle tracking display system (display system) enters a standby state, in which the execution module 4 is not powered on, and the passengers in the vehicle can freely move the vehicle tracking display system (display system) to a suitable position, and the position is kept fixed by the damping of the execution module 4 itself. When the control module 3 receives the second trigger signal (trigger signal 2) within the timing duration of the timer 31, the timing duration of the timer 31 is reset to zero, and the timer 31 is in the off state. The vehicle-mounted tracking display system (display system) enters the running state. Before the vehicle-mounted tracking display system (display system) enters the running state, the control module 3 sends a prompt message to the vehicle-mounted system 6. The prompt message is used to prompt the vehicle-mounted system 6 that the working state of the vehicle-mounted tracking display system (display system) is the running state. Accordingly, the vehicle-mounted system 6 receives the prompt message and can remind the occupants in the vehicle through the vehicle speaker that the vehicle-mounted tracking display system enters the running state. Among them, the execution module 4 is used to receive the control instruction sent by the control module 3 when the vehicle-mounted tracking display system is in the running state, and based on the control instruction, control the mobile display device 1 so that the screen display direction of the display device 1 is opposite to the line of sight direction of the occupants in the vehicle, and the display position change speed of the display device 1 is consistent with the line of sight movement speed.

[0055] As a possible implementation method, when the timing duration of the timer 31 is exceeded or the fourth trigger signal (trigger signal 4) is received, the vehicle-mounted tracking display system (display system) enters a shutdown state and is folded and retracted.

[0056] As another possible implementation method, when the second trigger signal (trigger signal 2) is not received within the timing duration of the timer 31, or the third trigger signal (trigger signal 3) is received, the timer 31 in the control module 3 is started, and the vehicle-mounted tracking display system (display system) enters a standby state. In this state, the execution module 4 is not powered on, and the occupants in the vehicle can freely move the vehicle-mounted tracking display system (display system) to a suitable position, and the execution module 4 itself damps to keep the position fixed.

[0057] Through the vehicle tracking display system provided by this embodiment, compared with the current existing technology, the present disclosure can obtain in-vehicle data through the sensor module, and the in-vehicle data includes the first position data of the display device and the second position data of the eyes of the in-vehicle occupants; the control module is connected to the sensor module, the control module receives the first position data and the second position data, and generates a control instruction for adjusting the display device based on the first position data and the second position data; one end of the execution module is connected to the control module, and the other end of the execution module is connected to the display device, the execution module receives the control instruction, and based on the control instruction, controls the mobile display device so that the screen display direction of the display device is opposite to the line of sight direction of the in-vehicle occupants, and the display position change speed of the display device is consistent with the line of sight movement speed. Through the scheme in the present disclosure, the first position data of the display device and the second position data of the eyes of the in-vehicle occupants are obtained in real time through the sensor module, and based on the first position data and the second position data, a control instruction for adjusting the display device can be generated, and the execution module can realize that the display position change speed of the display screen of the in-vehicle screen is synchronized with the line of sight movement speed of the in-vehicle occupants according to the control instruction, so that the in-vehicle occupants do not need to look at the in-vehicle screen along one line of sight direction, thereby improving the riding experience of the in-vehicle occupants.

[0058] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
