[0002] To improve the problems of single layout mode, checking dimension and limiting boundary of in-vehicle display screens, existing vehicles are equipped with an integrated liftable screen, and the rising and falling strokes of the screen are set. Whether in the rising or falling state, the driver and passengers can have good visual experience highlights and a sense of driving ceremony.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the embodiments of the present invention.

[0052] Please refer to Figure 1 , a flowchart of a method for controlling the lifting of a vehicle display screen provided by an embodiment of the present invention, which is applied to the lifting control of the on-vehicle center console display screen. The method includes:

[0053] S11. Obtain the visual area of the driver and the target information on the display screen that needs to be observed by the driver. Among them, the visual area is the area where the driver observes the display screen through the vacant part of the steering wheel.

[0054] Specifically, the center console display screen can be a display screen set at the instrument position in front of the steering wheel, or a display screen that runs through the main driver to the co-driver on the center console. The target information of the vehicle is displayed through the display screen. The target information can be one or more of driving state information, fuel consumption information, speed information, navigation information, etc. The steering wheel structure includes a four-spoke steering wheel, a three-spoke steering wheel, and a two-spoke steering wheel. There are vacant parts in steering wheels of different structures, and the area where the display screen is observed through the vacant part is the visual area.

[0055] In a specific implementation manner, obtaining the visual area of the driver includes:

[0056] Obtain the eye point position of the driver; the area where the eye point position radiates to the display screen through the vacant part of the steering wheel is determined as the visual area.

[0057] Specifically, the eye point position can be preset according to the experience of technicians; of course, it can also be determined according to the corresponding specifications. Please refer to Figure 2-3 , the eye point position can be determined according to the J941 specification formula requirements of SAE (Society of British Automotive Engineers). The eye point is characterized in an elliptical manner and includes Eysllipse Axes (X), Eysllipse Axes (Y), and Eysllipse Axes (Z) in the coordinate. According to the specification, the ellipses of the left and right eyes and the central eye point (i.e., the eye point position) of 95% of the drivers can be determined. The formula includes:

[0058] XXC = L + 644 + 0.587L6 - 0.76H30 - 5t

[0059] Ycl = W0 - 3.5

[0060] Ycl = W0 + 3.5

[0061] ZC = H8 + 638 + H30

[0062] Among them, L1 is the X coordinate of the PRP, L6 is the X-plane distance from the center of the steering wheel to the PRP, H30 is the Z-plane distance from the SgRP to the AHP, t is the transmission type (1 means there is a clutch pedal, 0 means there is no clutch pedal), W20 is the Y coordinate of the SgRP, and H8 is the Z coordinate of the AHP.

[0063] Please refer to Figure 4 , the eye point 1 includes the left eye point and the right eye point. When radiating the eye point 1 at the eye point position to the steering wheel, due to the occlusion of the outer ring of the steering wheel on the driver's vision, there will be an outer ring blind area 2, and the outer ring blind area 2 includes the left eye outer ring blind area 21 and the right eye outer ring blind area 22; similarly, please refer to Figure 5 , due to the occlusion of the center column and spokes of the steering wheel on the driver's vision, there will be a column and spoke blind area 3. Please refer to Figure 6 , the area in the middle of the blind area is the visible area 6. After obtaining the visible area and the target information, enter step S12.

[0064] S12. Determine the lifting range of the display screen according to the vertical floating range of the target information in the visible area.

[0065] Specifically, please continue to refer to Figure 6 , the display screen 4 is inclined in front of the direction. The area where the driver observes the display screen 4 through the vacant area of the steering wheel is the visible area 6. The target information 5 is in the visible area 6. When the target information 5 vertically floats in the visible area 6, the driver can observe the target information 5. Therefore, determining the lifting range of the display screen through the vertical floating range can meet the driving needs of the driver.

[0066] In a specific embodiment, the target information is instrument information. Determining the lifting range of the display screen according to the vertical floating range of the target information in the visible area includes:

[0067] Obtain the upper limit of the rise of the display screen according to the coincidence position of the upper display boundary of the instrument information and the visible upper boundary of the visible area; obtain the lower limit of the fall of the display screen according to the coincidence position of the lower display boundary of the instrument information and the visible lower boundary of the visible area; obtain the lifting range according to the upper limit of the rise and the lower limit of the fall.

[0068] Specifically, the instrument information usually includes the tachometer of the engine, the speedometer of the vehicle, the fuel gauge, and the water temperature gauge. Among them, the tachometer and the speedometer occupy a relatively large area of the visible area, usually with a diameter of 70-75 mm. The coincidence position of the upper display boundary of the instrument information and the visible upper boundary of the visible area is the rising limit value; similarly, the coincidence position of the lower display boundary of the instrument information and the visible lower boundary of the visible area is the falling limit value. When the display screen rises and falls between the rising limit value and the falling limit value, the driver can observe the instrument information through the vacant area of the steering wheel, ensuring safety during driving.

[0069] In specific implementation, since the forward vision range of the driver or the clarity of observing the display screen affects driving safety, when controlling the lifting of the display screen, the adverse effects brought by this factor need to be considered.

[0070] In a specific implementation manner, after determining the lifting interval of the display screen according to the vertical floating range of the target information in the visible area, it further includes:

[0071] Updating the lifting interval according to the vision quality index of the driver, where the vision quality index characterizes the forward vision range of the driver and / or the clarity of observing the display screen.

[0072] Specifically, the larger the forward vision range, the better the driving vision of the driver through the front windshield, and the higher the driving safety; on the contrary, the lower the driving safety. The higher the clarity of observing the display screen, the more accurate the target information obtained by the driver, and the higher the driving safety; on the contrary, the lower the driving safety. After characterizing the forward vision range and the clarity of observing the display screen through the vision quality index, the updated lifting interval can improve driving safety.

[0073] In a specific implementation manner, the vision quality index is the lower vision angle. Updating the lifting interval according to the vision quality index of the driver includes:

[0074] When the display screen is at the upper limit value of the lifting interval, obtain the lower vision angle, where the lower vision angle is the angle between the straight line from the driver's eye point position to the vertex of the display screen and the horizontal line; determine whether the lower vision angle is less than the preset angle; if so, update the upper limit value according to the lifting height corresponding to the preset angle.

[0075] Specifically, please refer to Figure 7When the display screen rises to the upper limit value of the lifting range, it is in the rising position 7. When the display screen drops to the lower limit value of the lifting range, it is in the falling position 8. At the rising position 7, the occlusion of the driver's forward vision is the largest. That is, the part above the vision boundary 9 is the forward vision visible to the driver. The vision boundary 9 is the tangent line of the bottom of the eye point 1 and the highest point of the display screen at the rising position 7. At the rising position 7, the lower vision angle in this state is obtained. If the lower vision angle is less than the preset angle, it means that when the display screen rises to the upper limit value, it has a greater impact on the occlusion of the forward vision, which will cause the driver to be unable to observe the road conditions in front of the vehicle head. The upper limit value is updated through the lifting height corresponding to the preset angle, and the influence of the display screen rising too high on the forward vision occlusion is reduced. The preset angle can be set to 5°.

[0076] In specific implementation, due to problems such as reflection when the driver observes the display screen, the target information observed may be inaccurate.

[0077] In a specific implementation manner, the vision quality index is the screen viewing angle. According to the driver's vision quality index, updating the lifting range includes:

[0078] Obtain the screen viewing angle, where the screen viewing angle is the angle between the line of sight of the driver observing the display screen and the perpendicular line of the display screen; determine whether the screen viewing angle is within the preset angle range; if not, update the lifting range according to the lifting height corresponding to the preset angle range.

[0079] Specifically, along with the lifting action of the display screen, the movement of the display screen is not in a completely vertical state. Please refer to Figure 8-9 The display screen 4 can be flipped and tilted through the fan-shaped flipping structure 10. During the process of the lifting height changing, the tilt angle also changes. To make the observed target information reach the best clarity effect, the best state is when the screen viewing angle is 90°. Therefore, the preset angle range can be set to 90°±10°, or it can be other angle ranges. If the screen viewing angle is not within the preset angle range, it means that the driver's viewing angle is relatively skewed, which may cause the observed target information to be blurred. Updating the lifting range according to the lifting height corresponding to the preset angle range, it can be understood that after updating, the range of the lifting range is further reduced.

[0080] In a specific implementation manner, the vision quality index is the viewing distance. According to the driver's vision quality index, updating the lifting range includes:

[0081] Obtain the viewing distance, where the viewing distance is the straight-line distance of the driver observing the display screen; determine whether the viewing distance is within the preset viewing distance range; if not, update the lifting range according to the lifting height corresponding to the preset viewing distance range.

[0082] Specifically, an excessively large or small viewing distance will also affect the target information to be observed. If the viewing distance is not within the preset viewing distance range, the lifting range is updated according to the lifting height corresponding to the preset viewing distance range, and the range of the lifting range is reduced. The viewing distance can be set to 700 ± 50 mm.

[0083] It should be noted that the field of view quality index can include one of the lower field of view angle, the screen viewing angle, and the viewing distance; it can also be three items. When the range of the lifting range is limited more, the viewing quality of the driver observing the target information on the display screen can be guaranteed, and the safety of the lifting control of the display screen is further improved. After determining the lifting range of the display screen, step S12 is entered.

[0084] S13. Control the display screen to lift and lower within the lifting range.

[0085] Specifically, the actuator for controlling the lifting and lowering of the display screen can be a motor with closed-loop control or a telescopic rod with closed-loop control, as long as the lifting and lowering control of the display screen can be achieved through the corresponding mechanical structure. The instruction for controlling the lifting and lowering can be issued by the vehicle central control controller. For example, an up button and a down button are set on the vehicle console, and by the driver operating the corresponding button, the central control controller is triggered to issue an instruction for controlling the lifting and lowering of the display screen.
