[0034] Example 1:

[0035] The embodiment provides a follow-up HUD system, which realizes six-way adjustment of the HUD in up-down, left-right and front-back directions through a three-axis movement mechanism, so as to realize follow-up adjustment of the position of the HUD and the visual angle of the driver; as shown in the figure, the follow-up HUD system mainly comprises a HUD body 2, a three-axis movement mechanism and an A-pillar camera 11, the HUD body 2 is a HUD host display system, which is installed on the upper side of the three-axis movement mechanism; the A-pillar camera 11 is installed on a driver's side A-pillar 10 and is used for acquiring the driving visual angle of the driver. Figure 1

[0036] The three-axis movement mechanism comprises an X-direction movement module, a Y-direction movement module and a Z-direction movement module, wherein the X-direction movement refers to left-right movement, the Y-direction movement refers to front-back movement, and the Z-direction movement refers to up-down movement (lifting movement); the X-direction movement module, the Y-direction movement module and the Z-direction movement module are sequentially arranged from bottom to top, and the HUD body 2 is connected to the upper side of the Z-direction movement module.

[0037] Specifically, the X-direction movement module comprises an X-direction moving track 6 and an X-direction moving block 8, the X-direction moving block 8 is in sliding connection with the X-direction moving track 6, and the X-direction moving block 8 can move along the X-direction moving track 6; the relative movement between the X-direction moving block 8 and the X-direction moving track 6 can be realized through a motor-driven screw nut mechanism.

[0038] The Y-direction movement module comprises a Y-direction moving track 7 and a Y-direction moving block 5, the Y-direction moving block 5 is in sliding connection with the Y-direction moving track 7, and the Y-direction moving block 5 can move along the Y-direction moving track 7; the relative movement between the Y-direction moving block 5 and the Y-direction moving track 7 can be realized through a motor-driven screw nut mechanism. The Y-direction moving track 7 is fixed on the upper side of the X-direction moving block 8 and moves together with the X-direction moving block 8.

[0039] The Z-direction movement module is a mechanism for realizing lifting, in the embodiment, the Z-direction movement module comprises a Z-direction power source 4 and a lifting component 3, the Z-direction power source 4 is fixed on the Y-direction moving block 5 and can provide linear power; one end of the lifting component 3 is connected to the Z-direction power source 4, and the other end is connected to the HUD body 2; the height of the HUD body 2 is adjusted under the action of the Z-direction power source 4. The Z-direction power source 4 can be a linear motor, an air cylinder or a hydraulic cylinder.

[0040] It can be understood that, in other embodiments, the Z-direction movement module can also be a motor-driven slide rail and slide block structure, a motor-driven chain mechanism and the like.

[0041] Since the visual position of the driver changes when the driver adjusts the seat, the A-pillar camera 11 installed on the driver's side A-pillar 10 collects the eye position information of the driver, the visual field of the driver is monitored in real time, the HUD body 2 is adjusted along with the change of the seat, that is, the HUD is adjusted in follow-up, so that the driver can conveniently view. ​

[0042] This embodiment is based on the camera's viewing height and presets the HUD change position at the corresponding height. After reaching the corresponding position, it is actively adjusted through a three-axis motion mechanism; thus solving the problem of drivers having to readjust their seat positions to adapt to the HUD position when changing.

[0043] Example 2:

[0044] This embodiment provides a vehicle equipped with the follow-up HUD system described in Embodiment 1, such as... Figure 1 As shown, the dust baffle 1 is located between the windshield and the follow-up HUD system. Based on the working limit positions of the HUD body 2 in the X, Y, and Z directions, corresponding marks are made on the dust baffle 1 and the windshield display area 9. During mass production, the dust baffle 1 and the windshield display area 9 can be adapted to the working limit position areas of the three-axis motion mechanism, which is convenient for adapting to various extreme driving postures of the HUD.

[0045] like Figure 2 As shown, the vehicle's steering wheel is equipped with buttons for controlling the three-axis motion mechanism, including a forward movement button 12, a backward movement button 14, a left movement button 15, a right movement button 13, an upward movement button 16, and a downward movement button 17. By controlling the movement of the HUD body 2 through the corresponding buttons, the driver can manually adjust the HUD, i.e., in manual mode.

[0046] In addition to manual mode, there are also automatic mode and seat follow mode. Automatic mode and seat follow mode control the HUD based on the driver's field of vision angle collected by A-pillar camera 11.

[0047] It should be noted that the up-moving button 16 and the down-moving button 17 can be implemented using a dial.

[0048] Example 3:

[0049] This embodiment provides a control method for a follow-up HUD system. Based on the HUD system described in Embodiment 1, the A-pillar camera 11 first acquires the driver's driving perspective and sends it to the control system. The control system outputs adjustment parameters according to the calculation results, and the three-axis motion mechanism adjusts the position of the HUD body 2 according to the adjustment parameters.

[0050] The HUD body 2 can be adjusted in three ways: automatic mode, manual mode, or seat-following mode. Specifically:

[0051] (1) Automatic mode:

[0052] When the driver sits on the seat, the A-pillar camera 11 installed on the A-pillar 10 on the driver's side is started to obtain a video or image of the driver's view angle and transmit the video or image to the control system. In the control system, the processor processes the video or image to obtain a calculation result, and provides an adjustment parameter of the HUD based on the calculation result.

[0053] The adjustment of the HUD is divided into the following cases:

[0054] When the height needs to be adjusted, the control system sends a height adjustment signal to the Z-direction power source 4, and the Z-direction power source 4 adjusts the height (up or down) of the HUD body 2 through the lifting component 3.

[0055] When the front-rear distance needs to be adjusted, the control system sends a front-rear displacement adjustment signal to the motor in the Y-direction movement module, and the front-rear movement of the HUD body 2 is realized by the movement of the Y-direction moving block 5 along the Y-direction moving rail.

[0056] When the left-right distance needs to be adjusted, the control system sends a left-right displacement adjustment signal to the motor in the X-direction movement module, and the left-right movement of the HUD body 2 is realized by the movement of the X-direction moving block 8 along the X-direction moving rail.

[0057] (2) Manual mode:

[0058] The driver adjusts the HUD through the keys on the steering wheel, which is divided into the following cases:

[0059] Height adjustment: When the HUD needs to be raised, the upward moving key 16 is operated to make the Z-direction power source 4 control the lifting component 3 to raise the HUD body 2, and the signal duration is combined to make the HUD body 2 continuously move upward until it is paused at the limit position. When the HUD needs to be lowered, the downward moving key 17 is operated to make the Z-direction power source 4 control the lifting component 3 to lower the HUD body 2, and the signal duration is combined to make the HUD body 2 continuously move downward until it is paused at the limit position.

[0060] Front-rear position adjustment: When the HUD needs to be moved forward by a certain distance, the forward moving key 12 is pressed to make the motor in the Y-direction movement module control the Y-direction moving block 5 to move forward along the Y-direction moving rail 7, and the signal duration is combined to make the HUD body 2 continuously move forward until it is paused at the limit position. When the HUD needs to be moved backward by a certain distance, the backward moving key 14 is pressed to make the motor in the Y-direction movement module control the Y-direction moving block 5 to move backward along the Y-direction moving rail 7, and the signal duration is combined to make the HUD body 2 continuously move backward until it is paused at the limit position.

[0061] Similarly, left and right position adjustment: when the HUD needs to be adjusted to move a certain distance to the left, press the left moving button 15 to control the motor in the X direction movement module to move the X direction moving block 8 along the X direction moving track 6 to the left; when the HUD needs to be adjusted to move a certain distance to the right, press the right moving button 13 to control the motor in the X direction movement module to move the X direction moving block 8 along the X direction moving track 6 to the right. During the left and right movement, the signal input duration is always controlled to pause according to the signal interruption, and if the signal input is continuous, it will always move to the corresponding end limit position of the track and pause.

[0062] (3) Seat follow-up mode:

[0063] When the driver adjusts the seat to the appropriate sitting posture, the seat follow-up mode is selected, and the HUD position matching the current driver's sitting posture is adjusted through the automatic mode.

[0064] At this time, if the driver adjusts the front and rear seat changes, the driver's view angle changes are obtained through the A-pillar camera 11, and signals are sent to the motor in the Y direction movement module through the control system, so that the motor drives the Y direction moving block 5 to move forward and backward along the Y direction moving track 7, and the optimal HUD position visible to the driver is always maintained.

[0065] If the driver adjusts the height of the seat, the driver's view angle changes are obtained through the A-pillar camera 11, and if the seat height is adjusted, the control system sends signals to the Z direction power source 4, and the height of the HUD body 2 is adjusted through the preset parameter value to always maintain the optimal HUD position visible to the driver.

[0066] If the driver adjusts the left and right seat changes, the driver's view angle changes are obtained through the A-pillar camera 11, and signals are sent to the motor in the X direction movement module through the control system, so that the motor drives the X direction moving block 8 to move left and right along the X direction moving track 6, and the optimal HUD position visible to the driver is always maintained.

[0067] In this embodiment, whether it is an automatic mode, a manual mode or a seat follow-up mode, the adaptability of the HUD position to the seat can be guaranteed, and different driver view positions can be adapted to achieve the best visual effect.

[0068] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
