[0034] Embodiment 1:

[0035] This embodiment provides a follow-up HUD system, which realizes six-way adjustment of the HUD up and down, left and right, and front and back by setting a three-axis motion mechanism, thereby realizing follow-up adjustment of the HUD position and the driver's field of view angle; Figure 1 As shown, the follow-up HUD system mainly includes a HUD body 2, a three-axis motion 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 motion mechanism; the A-pillar camera 11 is installed on the A-pillar 10 on the main driver's side to obtain the driver's driving perspective.

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

[0037] Specifically, the X-axis motion module includes an X-axis moving rail 6 and an X-axis moving block 8. The X-axis moving block 8 is slidably connected to the X-axis moving rail 6, and the X-axis moving block 8 can move along the X-axis moving rail 6; the relative movement of the X-axis moving block 8 and the X-axis moving rail 6 can be achieved by a screw nut mechanism driven by a motor.

[0038] The Y-direction motion module includes a Y-direction moving track 7 and a Y-direction moving block 5. The Y-direction moving block 5 is slidably connected to 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 of the Y-direction moving block 5 and the Y-direction moving track 7 can be achieved by a lead screw nut mechanism driven by a motor. The Y-direction moving track 7 is fixed to the upper side of the X-direction moving block 8 and moves with the X-direction moving block 8.

[0039] The Z-direction motion module is a mechanism for realizing lifting. In this embodiment, the Z-direction motion module includes 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 adjustment of the HUD body 2 is realized under the action of the Z-direction power source 4. The Z-direction power source 4 can be a linear motor, a cylinder, a hydraulic cylinder, etc.

[0040] It is understandable that in other embodiments, the Z-axis motion module may also be a motor-driven slide rail and slider structure, a motor-driven chain mechanism, etc.

[0041] As the driver's field of vision changes when adjusting the seat, the A-pillar camera 11 installed on the A-pillar 10 on the main driver's side collects the driver's eye position information, monitors the driver's field of vision in real time, and adjusts the HUD body 2 as the seat changes, that is, the HUD is adjusted dynamically, so as to facilitate the driver's viewing.

[0042] This embodiment presets the HUD change direction of the corresponding height based on the visual height of the camera. After reaching the corresponding position, it is actively adjusted through the three-axis motion mechanism, solving the problem of readjusting the seat position to adapt to the HUD position due to the driver's change.

[0043] Embodiment 2:

[0044] This embodiment provides a vehicle, which is equipped with the follow-up HUD system described in Embodiment 1, such as Figure 1 As shown, the dust shield 1 is arranged between the windshield and the follow-up HUD system. Combined with the working limit positions of the HUD body 2 in the X direction, the Y direction, and the Z direction, the dust shield 1 and the windshield display area 9 are marked accordingly. During mass production, the dust shield 1 and the windshield display area 9 can be adapted to the working limit position area of ​​the three-axis motion mechanism, so as to adapt to various extreme driving postures to the HUD.

[0045] like Figure 2 As shown, the steering wheel of the vehicle is provided 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. The movement of the HUD body 2 is controlled by the corresponding buttons to enable the driver to manually adjust the HUD, that is, the manual mode.

[0046] In addition to the manual mode, an automatic mode and a seat follow-up mode are also provided. The automatic mode and the seat follow-up mode control the HUD based on the driver's field of view angle captured by the A-pillar camera 11 .

[0047] It should be noted that the upward movement button 16 and the downward movement button 17 can be implemented in the form of a dial wheel.

[0048] Embodiment 3:

[0049] The present embodiment provides a control method for a follow-up HUD system. Based on the HUD system described in Example 1, first, the A-pillar camera 11 obtains 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 adjustment methods of the HUD body 2 position are divided into automatic mode, manual mode or seat follow-up mode, specifically:

[0051] (1) Automatic mode:

[0052] When the driver sits in the seat, the A-pillar camera 11 installed on the A-pillar 10 on the main driver's side is started to obtain video or images from the driver's perspective, and the video or image is transmitted to the control system. In the control system, the processor processes the video or image to obtain a calculation result, and provides adjustment parameters of the HUD based on the calculation result.

[0053] Adjustments to the HUD are divided into the following situations:

[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 (increases or decreases) of the HUD body 2 through the lifting component 3 .

[0055] When the front-to-back distance needs to be adjusted, the control system sends a front-to-back displacement adjustment signal to the motor in the Y-motion module, and the front-to-back movement of the HUD body 2 is achieved by the movement of the Y-motion block 5 along the Y-motion guide 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 motion module, and the left-right movement of the HUD body 2 is achieved by moving the X-direction moving block 8 along the X-direction moving guide rail.

[0057] (2) Manual mode:

[0058] The driver adjusts the HUD through the buttons on the steering wheel, which can be divided into the following situations:

[0059] Height adjustment: When the HUD needs to be raised, the upward movement button 16 is operated to make the Z-direction power source 4 control the lifting component 3 to drive the HUD body 2 to rise, and combined with the signal duration, the HUD body 2 continues to move upward until it reaches the limit position and then pauses. When the HUD needs to be lowered, the downward movement button 17 is operated to make the Z-direction power source 4 control the lifting component 3 to drive the HUD body 2 to descend, and combined with the signal duration, the HUD body 2 continues to move downward until it reaches the limit position and then pauses.

[0060] Front and rear position adjustment: When the HUD needs to be adjusted to move forward a certain distance, by pressing the forward movement button 12, the motor in the Y-motion module controls the Y-motion block 5 to move forward along the Y-motion track 7. According to the duration of the signal input, the control pauses at any time according to the signal interruption. If the signal input is continuous, it will move forward to the front limit position of the track and pause. When the HUD needs to be adjusted to move backward a certain distance, by pressing the backward movement button 14, the motor in the Y-motion module controls the Y-motion block 5 to move backward along the Y-motion track 7. According to the duration of the signal input, the control pauses at any time according to the signal interruption. If the signal input is continuous, it will move backward to the rear limit position of the track and pause.

[0061] Similarly, left and right position adjustment: when the HUD needs to be adjusted to move to the left by a certain distance, by pressing the left movement button 15, the motor in the X-direction motion module controls the X-direction motion block 8 to move to the left along the X-direction motion track 6; when the HUD needs to be adjusted to move to the right by a certain distance, by pressing the right movement button 13, the motor in the X-direction motion module controls the X-direction motion block 8 to move to the right along the X-direction motion track 6. During the left and right movement, the control pauses at any time according to the duration of the signal input and the signal interruption. If the signal input continues, it will move to the corresponding end of the track and pause.

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

[0063] When the driver adjusts the seat to a suitable sitting posture, by selecting the seat follow-up mode, the HUD position will be automatically adjusted to match the current driver's sitting posture.

[0064] At this time, if the driver adjusts the front and rear seats, the A-pillar camera 11 will obtain the driver's viewing angle changes, and send a signal to the motor in the Y-axis motion module through the control system. As the seat moves forward and backward, the motor drives the Y-axis moving block 5 to move forward and backward along the Y-axis moving track 7, always maintaining the best HUD position visible to the driver.

[0065] If the driver adjusts the height of the seat, the A-pillar camera 11 will obtain the change in the driver's viewing angle. If the seat moves, the control system will send a signal to the Z-direction power source 4 to adjust the height change of the HUD body 2 through the preset parameter value to always maintain the best HUD position visible to the driver.

[0066] If the driver adjusts the left and right seats, the A-pillar camera 11 will obtain the driver's perspective change, and send a signal to the motor in the X-direction motion module through the control system. As the seat moves left and right, the motor drives the X-direction moving block 8 to move left and right along the X-direction moving track 6, always maintaining the best HUD position visible to the driver.

[0067] In this embodiment, whether it is automatic mode, manual mode or seat follow-up mode, the adaptive adjustment of the HUD position and the seat can be guaranteed, and it can adapt to different driver viewing angles to achieve the best visual effect.

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