Abstract
Description
Technical Field
[0001] This invention relates to a method for arranging electronic exterior rearview mirror monitors, and particularly to a method for arranging electronic exterior rearview mirrors and monitors. Background Technology
[0002] As a product in the field of indirect vision devices, electronic exterior rearview mirrors use cameras to collect road conditions within the field of view of traditional rearview mirrors and display them on the in-vehicle monitor. This not only effectively expands the driver's field of vision and improves the rearview effect in adverse environments and avoids blind spots, but also reduces the vehicle's air resistance and increases the futuristic feel of the overall vehicle design.
[0003] Electronic exterior rearview mirror monitors typically come in two forms: embedded, which integrates with the interior trim panel and is integrated into it; and floating, where the monitor is independently suspended on the interior trim panel or dashboard. Regardless of the form, if the monitor's placement is inappropriate, it can make it difficult for the driver to see the information. Furthermore, the driver's frequent switching of gaze while driving (looking at the monitor and then immediately looking at the road ahead) can easily cause dizziness, affecting driving safety. Summary of the Invention
[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a method for arranging an electronic exterior rearview mirror monitor, which can help drivers conveniently observe road conditions, with an unobstructed screen to avoid dizziness and improve comfort.
[0005] To achieve the above objectives, the present invention provides a method for arranging an electronic exterior rearview mirror monitor, the monitor including a left monitor and a right monitor, the left monitor and the right monitor being arranged on the left and right sides of the vehicle's interior dashboard, respectively, the center point of the left monitor screen and the center point of the right monitor screen being symmetrically arranged with respect to the longitudinal reference plane of the vehicle, and the normals of the center points of the left monitor and the right monitor screen both passing through the driver's eye point.
[0006] Preferably, when the driver is on the left side of the vehicle, the left-side monitor is arranged as follows: a plane is drawn from point Pm in the direction of vehicle travel at a 5° angle downwards from the horizontal plane, and a horizontal plane is drawn at the foremost point where the plane intersects with the A-pillar. This horizontal plane serves as the highest limiting plane in the height direction of the left-side monitor, wherein the position of point Pm is determined by the GB11562 standard; when the driver is on the right side of the vehicle, the right-side monitor is arranged in the same manner.
[0007] Preferably, when the driver is on the left side of the vehicle, the left-side monitor is arranged in such a way that the S2 section specified in GB11562 standard is used as the highest limiting surface in the height direction of the left-side monitor; when the driver is on the right side of the vehicle, the right-side monitor is arranged in the same way.
[0008] Preferably, when the driver is on the left side of the vehicle, the left-side monitor is arranged such that it extends at least 500 mm from point H in the direction of vehicle travel, and at most does not exceed the heel point as the front-rear directional limit of the left-side monitor, wherein the position of point H is determined by the GB11562 standard; when the driver is on the right side of the vehicle, the right-side monitor is arranged in the same manner.
[0009] Preferably, when the driver is on the left side of the vehicle, the left monitor is arranged as follows: with the driver's eye point as the origin, a straight line at a 55° angle to the longitudinal reference plane of the vehicle is drawn, and this straight line serves as the leftmost boundary of the left monitor; when the driver is on the right side of the vehicle, the right monitor is arranged in the same manner.
[0010] Preferably, when the driver is on the left side of the vehicle, the left-side monitor is arranged in such a way that the boundary of the door panel is the leftmost limiting surface boundary of the left-side monitor; when the driver is on the right side of the vehicle, the right-side monitor is arranged in the same way.
[0011] Preferably, when the driver is on the left side of the vehicle, the left-side monitor is arranged as follows: with the driver's eye level as the origin, a tangent line is drawn through the outer contour of the steering wheel, and this tangent line extends around the outer contour of the steering wheel to form a surface that covers the steering wheel. This surface covering the steering wheel serves as the right boundary of the left-side monitor. When the driver is on the right side of the vehicle, the right-side monitor is arranged in the same manner.
[0012] Preferably, both the left and right monitors are arranged in a manner that is not obstructed by the steering wheel.
[0013] The present invention also provides an electronic exterior rearview mirror, including a left-side monitor and a right-side monitor, wherein the left-side monitor and the right-side monitor respectively display the road conditions to the left and right rear of the vehicle; the left-side monitor and the right-side monitor are arranged using the arrangement method of the electronic exterior rearview mirror monitor described in any of the preceding claims.
[0014] The present invention also provides a vehicle having the aforementioned electronic exterior rearview mirror, or having the electronic exterior rearview mirror monitor arranged using any of the aforementioned arrangement methods.
[0015] Compared with the prior art, the advantages of this invention are:
[0016] (1) In the arrangement method of the electronic rearview mirror monitor of the present invention, the normal line of the center of the left and right monitor screens needs to pass through the driver's eye point, which can ensure that the driver can intuitively and accurately observe the information on the monitor screen.
[0017] (2) The arrangement of the electronic exterior rearview mirror monitor of the present invention takes into account the steering wheel and can ensure that the monitor is not obstructed by the steering wheel.
[0018] (3) The arrangement of the electronic rearview mirror monitor of the present invention scientifically limits the range of height, front and rear, and left and right directions, which can help the driver to conveniently observe the road conditions. The screen is unobstructed, avoiding dizziness and improving driving comfort. The optimal arrangement position and angle of the left and right monitors can be obtained, and the regulatory requirements are met without affecting other regulatory requirements.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] The following description of the first embodiment of the present invention is presented with the driver and steering wheel on the left side of the vehicle.
[0031] The first principle to clarify is that the center point of the right monitor 52 screen and the center point of the left monitor 51 screen are symmetrically arranged with respect to the longitudinal reference plane of the entire vehicle; the normals of the center points of the right monitor 52 screen and the left monitor 51 screen must coincide with the driver's eye level. The specific arrangement is as follows:
[0032] Left monitor position 51:
[0033] 1. Draw a plane at a 5° angle downwards from point Pm. Draw a horizontal plane at the foremost point where this plane intersects with column A1. This horizontal plane is the highest limiting plane in the Z direction of the monitor.
[0034] 2. The area 500mm in front of point H and not exceeding the heel point is the X-axis limit range of the monitor;
[0035] 3. Using the driver's eye point as the origin, draw a straight line at a 55° angle to the longitudinal reference plane of the vehicle. This straight line is the leftmost boundary of the monitor.
[0036] 4. With the driver's eye point as the origin, draw a tangent line to the outer contour of the steering wheel 4. The surface formed by this tangent line, when extended, becomes the boundary on the right side of the monitor.
[0037] 5. To ensure that the driver can easily and safely observe the content on the monitor, the normal line of the center point of the monitor screen must coincide with the driver's eye point when the monitor is set up.
[0038] Right monitor position 52:
[0039] 1. The center point of the right monitor 52 is symmetrical to the center point of the left monitor 51.
[0040] 2. In order to ensure that the driver can easily and safely observe the contents of the right monitor 52, the normal of the center point of the right monitor 52 screen must coincide with the driver's eye point when the monitor is set up.
[0041] Figure 1 This is a schematic diagram illustrating the manufacturing method of the highest limiting surface in the Z direction of the monitor according to the present invention. The manufacturing method is detailed as follows: 1. GB 11562 specifies the location of point Pm; 2. Draw a plane at a 5° angle downwards from point Pm, and construct a horizontal plane at the foremost point where this plane intersects with column A1; 3. This horizontal plane is the highest limiting surface in the Z direction of the monitor; 4. The cross-section where this horizontal plane intersects with column A1 is also the S2 cross-section specified in GB 11562.
[0042] The monitor, positioned below this limiting surface, will not increase the A-pillar obstruction angle of the vehicle.
[0043] Figure 2 This is a schematic diagram of a method for manufacturing the X-axis limiting range of a monitor. The manufacturing method is detailed as follows: 1. Obtain the H-point of the human body as specified in GB 11562, and create a vertical plane 500mm in front of the H-point; 2. Obtain the heel point of the human body, and create a vertical plane with the heel point as the origin; 3. The area 500mm in front of the H-point and not exceeding the heel point is the X-axis limiting range of the monitor.
[0044] Figure 3 This is a schematic diagram illustrating the method for fabricating the leftmost limiting boundary of the monitor according to the present invention. The detailed fabrication method is as follows: 1. Obtain the human eye point; 2. Construct a vertical plane at a 55° angle to the vertical reference plane; 3. This vertical plane is the leftmost limiting boundary of the monitor. Therefore, the boundary range is relatively large, and since the monitor of the electronic rearview mirror is basically located inside the cabin, the boundary of the door panel 6 is usually used as the leftmost limiting boundary of the monitor.
[0045] Figure 4 This is a schematic diagram illustrating the method for creating the rightmost limiting boundary of the monitor according to the present invention. Because the monitor is positioned in front of the steering wheel 4, if the monitor is not positioned correctly, the steering wheel 4 may obstruct the driver's view of the monitor. Therefore, the method for creating the rightmost limiting boundary of the monitor is as follows: 1. Obtain the human eye point; 2. Obtain the outermost contour of the steering wheel 4; 3. With the driver's eye point as the origin, draw a tangent line to the outer contour of the steering wheel 4. The surface formed by this tangent line, when extended, becomes the right boundary of the monitor. That is, the tangent surface of the steering wheel serves as the right boundary of the monitor. When the monitor is positioned on the dashboard, the right boundary is the intersection of the tangent surface of the steering wheel and the dashboard.
[0046] Figure 5This is a schematic diagram illustrating the monitor arrangement angle method of the present invention. To ensure that the driver can intuitively and accurately observe the information on the monitor screen, the normal line at the center of the monitor screen must pass through the driver's eye level. This arrangement angle is the optimal arrangement angle.
[0047] Figure 6 This is a schematic diagram of the front, rear, left, and right boundaries of the monitor of the present invention. Figure 6 and Figure 1 Integration refers to the boundary of the monitor placement. As can be seen from the diagram, after the monitor's position is constrained by the above boundaries, the optimal placement position can be determined. This position is not obstructed by the steering wheel 4 and does not affect the regulatory requirements such as the A-pillar 1 obstruction angle.
[0048] Figures 1-6 The arrangement of the left-side monitor 51. Figure 7 This is a schematic diagram of the left and right monitor arrangement of the present invention. The center point of the right monitor 52 screen and the center point of the left monitor 51 screen are symmetrically arranged with respect to the longitudinal reference plane of the vehicle. After the left monitor 51 is arranged, the center point of the right monitor 52 screen is immediately determined. Because the right screen is far from the driver, the angle of the right monitor 52 needs to be adjusted to ensure that the driver can intuitively and accurately observe the information on the right monitor 52 screen. Similar to the method of arranging the angle of the left monitor 51, the normal line of the center of the right monitor 52 screen must pass through the driver's eye level. This arrangement angle is the optimal arrangement angle.
[0049] By using the above methods, the optimal placement and angle of the left and right monitors can be obtained, meeting regulatory requirements without affecting other regulatory requirements.
[0050] The vehicle coordinate system used in this invention patent is a special moving coordinate system used to describe the motion of a car; its origin coincides with the center of mass. When the vehicle is stationary on a horizontal road, the X-axis is parallel to the ground and points in front of the vehicle, the Z-axis passes through the center of mass of the car and points upward, and the Y-axis points to the left of the driver.
[0051] To illustrate the invention, the first embodiment described above depicts a scenario where the driver and steering wheel 4 are on the left side of the vehicle.
[0052] The second embodiment of the present invention describes the scenario where the driver and steering wheel 4 are on the right side of the vehicle. It should be noted that when the driver and steering wheel 4 are on the right side of the vehicle, those skilled in the art, using the longitudinal reference plane of the entire vehicle as the center plane, should understand the arrangement of the left-side monitor 51 described above.
[0053] The same principle applies to the right monitor 52. First, determine the position of the right monitor 52, and then determine the position of the left monitor 51. This will not be elaborated further here.
[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
