[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to a Chinese patent application filed with the China Patent Office on October 27, 2023, with application number 2023114072606 and titled “Black-border display window and vehicle.” The entire contents of the patent application are incorporated by reference into this disclosure. Technical Field

[0003] The present application relates to the field of vehicle window technology, and in particular to a black-border display vehicle window and a vehicle. Background Art

[0004] With the evolution of the era of intelligent network connectivity, vehicles can provide various types of information to passengers, such as vehicle information, road information, social media information, etc. This can generally be achieved through the use of vehicle head-up displays (HUDs), instrument panels, central control screens, co-pilot displays, etc., and their combinations, to meet multi-format, near- and far-level display needs, thereby bringing passengers a more comfortable, safe, and intelligent experience and rich information.

[0005] Displays such as instrument panels and central control screens require the driver to lower their head to observe, temporarily diverting their eyes away from the road, posing a safety hazard. Traditional head-up displays (HUDs) display the HUD image in the light-transmitting area of ​​the windshield, with the exterior environment serving as the HUD image's background. Ambient brightness and other interfering light can affect the driver's ability to perceive the HUD image, compromising driving safety and visual comfort.

[0038] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0039] As shown in FIG1 , the present application provides a black-bordered display window that can be installed on a vehicle for use as a front windshield, rear windshield, or side window. The black-bordered display window includes a glass body 10 and a functional reflective element 20. The glass body 10 is provided with a light-transmitting area 101 and a shielding area 102 arranged circumferentially around the light-transmitting area 101. The light-transmitting area 101 has a visible light transmittance greater than or equal to 70%, which facilitates the observation of the external environment by the occupants of the vehicle through the light-transmitting area 101. The visible light transmittance of the shielding area 102 is less than or equal to 5%, which facilitates shielding, protection, and enhancing the overall aesthetics. The functional reflective element 20 is disposed within the shielding area 102 of the glass body 10.

[0040] In Figure 1 , the shielding area 102 includes a bottom shielding area 1021 located below the light-transmitting area 101, and the functional reflective element 20 is disposed in the bottom shielding area 1021. Optionally, the shielding area 102 also includes a left shielding area 1022 located to the left of the light-transmitting area 101, a top shielding area 1023 located above the light-transmitting area 101, and a right shielding area 1024 located to the right of the light-transmitting area 101. Preferably, the visible light transmittance of the shielding area 102 is less than or equal to 3%, more preferably less than or equal to 1%, or even equal to 0, i.e., completely opaque.

[0041] The present application can reflect the projection light 301 projected by the image generation unit 30 through the functional reflective element 20 to form an observable image, thereby partially replacing or even completely replacing the traditional instrument panel, or even eliminating the traditional instrument panel, so that the driver has a better field of vision and can use his sight for a longer time to observe the external situation, while being able to more easily obtain the necessary information for assisted driving, greatly improving driving safety; at the same time, the shielding area 102 is usually called the black edge area. The present application sets the functional reflective element 20 in the shielding area 102, especially in the bottom shielding area 1021, so that the shielding area 102, especially the bottom shielding area 1021, is used as the image display background, which can better block the external ambient light, avoid unnecessary interference with the line of sight, and make the image display clearer, achieving higher contrast and color gamut.

[0042] It should be noted that when in operation, the functional reflective element 20 can display vehicle driving information, various graphics, or play videos, and can be used in various scenarios such as welcoming guests, creating an atmosphere, watching movies, and working. Optionally, the functional reflective element 20 can be used to display driving parameters, including vehicle speed, engine speed, fuel consumption, tire pressure, warning information, mileage, etc. It can also be used to display weather temperature, entertainment information, dynamic navigation, night vision, real-life maps, etc.

[0043] As shown in Figure 2, in one embodiment, a black-bordered display window is used as a front windshield. The glass body 10 includes an outer glass panel 11, an adhesive layer 12, and an inner glass panel 13, which are laminated and connected in sequence. The outer glass panel 11 has a first surface 111 and a second surface 112 disposed opposite each other. The inner glass panel 13 has a third surface 131 and a fourth surface 132 disposed opposite each other. The second surface 112 is disposed opposite the third surface 131. The adhesive layer 12 is used to bond the outer glass panel 11 and the inner glass panel 13 together to form a laminated glass structure. When the black-bordered display window is installed on a vehicle, the outer glass panel 11 is located on the outside of the vehicle, and the first surface 111 is the outer surface of the black-bordered display window exposed to the outside of the vehicle. The inner glass panel 13 is located on the inside of the vehicle, and the fourth surface 132 is the inner surface of the black-bordered display window exposed to the inside of the vehicle.

[0044] The outer glass plate 11 is made of transparent glass or tinted glass, has a thickness of 0.7 mm to 4 mm, and has a visible light transmittance greater than 70%. The inner glass plate 13 is made of transparent glass or tinted glass, has a thickness of 0.7 mm to 4 mm, and has a visible light transmittance greater than 70%. The total iron content (calculated as Fe2O3) of the transparent glass is less than or equal to 0.1%, even less than or equal to 0.05%, and further less than or equal to 0.01%, and the visible light transmittance of the transparent glass is 80% to 95%; the total iron content (calculated as Fe2O3) of the tinted glass is 0.1% to 0.8%, even 0.1% to 0.5%, and the visible light transmittance of the tinted glass is 75% to 90%. For example, the outer glass plate 11 can be a transparent glass with a thickness of 2.1 mm and a visible light transmittance of 89%, and the inner glass plate 13 can be a green glass with a thickness of 1.6 mm and a visible light transmittance of 83%, or a green glass with a thickness of 2.1 mm and a visible light transmittance of 80%.

[0045] Wherein, the adhesive layer 12 is a transparent thermoplastic polymer film or a colored thermoplastic polymer film, and the thickness of the adhesive layer 12 is 0.38mm to 2.28mm. For example, the thickness of the adhesive layer 12 can be, but is not limited to, 0.38mm, 0.76mm, 1.14mm, 1.52mm, 1.9mm, 2.28mm, or other values ​​between 0.38mm and 2.28mm. The material of the thermoplastic polymer film can be selected from at least one of polyvinyl butyral (PVB), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), and ionomer (SGP). When the adhesive layer 12 is a transparent thermoplastic polymer, the visible light transmittance of the transparent thermoplastic polymer is greater than or equal to 80%. For example, the visible light transmittance of the adhesive layer 12 can be, but is not limited to, 80%, 85%, 90%, 95%, etc. When the adhesive layer 12 is a colored thermoplastic polymer film, the visible light transmittance of the colored thermoplastic polymer film is greater than 70%. For example, the visible light transmittance of the adhesive layer 12 may be, but is not limited to, 75%, 80%, 85%, or 90%. The colored thermoplastic polymer film may be a gray thermoplastic polymer film, a green thermoplastic polymer film, or a blue thermoplastic polymer film.

[0046] In some embodiments, the left shielding area 1022, the top shielding area 1023, and the right shielding area 1024 are all dark ink layers 14. Ceramic ink or ultraviolet ink is printed on the second surface 112 through a process such as screen printing or inkjet printing, and then cured or sintered at high temperature to form the dark ink layer 14. The dark ink layer 14 surrounds the peripheral edge areas of the second surface 112. It is understood that the dark ink layer 14 can also be located only on the third surface 131, or only on the fourth surface 132, or on both the second surface 112 and the fourth surface 132, or on both the second surface 112 and the third surface 131, or on both the third surface 131 and the fourth surface 132, or on all three surfaces. In order to prevent the left shielding area 1022, the top shielding area 1023 and the right shielding area 1024 from generating mirror reflections and interfering with the vision of the occupants of the vehicle, it is preferred that the surface roughness Ra of the dark ink layer 14 is greater than or equal to 1 μm, for example, 1.1 μm, 1.2 μm, 1.3 μm, 1.4 μm, 1.5 μm, 1.8 μm, 2.0 μm, 2.5 μm, 3.0 μm, 3.5 μm, 4.0 μm The surface roughness Ra of the dark ink layer 14 is preferably 2 μm to 8 μm, and the surface roughness Ra of the dark ink layer 14 is more preferably 4.5 μm to 7 μm. The surface roughness Ra value is measured by a surface roughness tester.

[0047] In the present application, the area in the bottom shielding area 1021 where the functional reflective element 20 is provided is the display area, and the other areas in the bottom shielding area 1021 where the functional reflective element 20 is not provided are the non-display areas. The image generation unit 30 projects the projection light 301 to the display area at an incident angle of 40° to 85°, and the display area reflects the incident projection light 301 into the eyes of the people in the car to form a display image. The display area has a first reflectivity RL1 greater than or equal to 8% for the incident projection light 301. Since the bottom shielding area 1021 serves as the display background of the display image, the power of the image generation unit 30 can be reduced to prevent the image generation unit 30 from overheating while obtaining a clear display image, thereby reducing the unit and volume of the image generation unit 30, which is conducive to design optimization and cost reduction. Preferably, the first reflectivity RL1 is greater than or equal to 10%, and specific examples include 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, etc., and is further preferably greater than or equal to 15%, further preferably greater than or equal to 20%, even greater than or equal to 25%, and even greater than or equal to 30%.

[0048] In some embodiments, in order to reduce the interference of the mirror reflection generated by the non-display area in the bottom shielding area 1021 on the display image generated by the display area, the non-display area has a second reflectivity RL2 for visible light incident at an incident angle of 0° to 8°. Preferably, the ratio of the first reflectivity RL1 to the second reflectivity RL2 is greater than or equal to 3, that is, RL1 / RL2 ≥ 3, and specific examples include 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20. More preferably, the ratio of the first reflectivity RL1 to the second reflectivity RL2 is greater than or equal to 5, further preferably greater than or equal to 8, further preferably greater than or equal to 10, even greater than or equal to 15, and even more preferably greater than or equal to 20. Specifically, the second reflectivity RL2 is less than or equal to 6%, preferably less than or equal to 4%, more preferably less than or equal to 3%, further preferably less than or equal to 2%, and even more preferably less than or equal to 1%. The first reflectivity RL1 and the second reflectivity RL2 may be measured according to the Chinese standard GB9656.

[0049] The image generation unit 30 is configured to generate projection light 301. The projection light 301 includes at least one of P-polarized light, circularly polarized light, and unpolarized light. Preferably, the projection light 301 includes at least 30% P-polarized light, so that passengers wearing polarized sunglasses can still clearly see the displayed image. Specifically, for example, the projection light 301 includes 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or even 100% P-polarized light. The image generation unit 30 can utilize a projector, which is mounted inside the instrument panel. The optical path is designed so that the displayed image is displayed at a distance of 0 to 5 meters in front of the black-bordered display window. The image generation unit 30 can also utilize a display screen, which can be mounted on the top surface of the instrument panel. The optical path is designed so that the displayed image is displayed at a distance of 0 to 0.5 meters in front of the black-bordered display window. In this application, the display image displayed at a distance of 0 meters in front of the black-bordered display window can be understood as the displayed image being directly displayed on the black-bordered display window. Specifically, the display screen can be exemplified by a thin film transistor display (TFT), an organic light emitting diode display (OLED), a liquid crystal on silicon (LCOS), a digital light processing display (DLP), a sub-millimeter light emitting diode display (Mini LED), a micro light emitting diode display (Micro LED), etc.

[0050] In some embodiments, the functional reflective element 20 may be a diffuse reflective projection layer having a reflectivity of at least 8% for the projection light 301 generated by the image generation unit 30. The projection light 301 forms a display image on the diffuse reflective projection layer, which is then directly displayed on the black-bordered display window. The diffuse reflective projection layer can achieve nearly uniform reflection in all directions according to the Lambertian model, or it can prioritize maximum reflectivity in the direction of observation by the vehicle occupant. Examples of the diffuse reflective projection layer include a black scattering coating, a white curtain, a transparent scattering layer, and the like. The diffuse reflective projection layer can be disposed on the second surface 112, between the second surface 112 and the third surface 131, on the third surface 131, or on the fourth surface 132. Preferably, the visible light transmittance of the diffuse reflective projection layer is less than or equal to 50%, and specific examples include 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, 1%, or 0%. More preferably, the visible light transmittance of the diffuse reflection projection layer is less than or equal to 5%, so that the diffuse reflection projection layer can serve as part of the bottom shielding area 1021. Preferably, the haze of the diffuse reflection projection layer is 2% to 10%, and specifically, for example, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10%.

[0051] In some embodiments, the functional reflective element 20 may be a P-polarized light reflective layer, which is used to increase the reflectivity of the display area to P-polarized light, so that the reflectivity of the display area to P-polarized light is greater than or equal to 8%. The P-polarized light reflective layer may be, for example, a high-low refractive index laminate, a metal laminate, or a polyethylene terephthalate (PET) laminate. The visible light transmittance of the P-polarized light reflective layer is greater than or equal to 70%. The P-polarized light reflective layer may be disposed on the second surface 112, between the second surface 112 and the third surface 131, on the third surface 131, or on the fourth surface 132.

[0052] In some embodiments, the functional reflective element 20 may be an S-polarized light reflective layer. The S-polarized light reflective layer is used to increase the reflectivity of the display area to S-polarized light, so that the reflectivity of the display area to S-polarized light is greater than or equal to 8%. The S-polarized light reflective layer may be, for example, a high-low refractive index stack or a metal stack. The S-polarized light reflective layer has a visible light transmittance greater than or equal to 70%. To prevent ghosting of the displayed image, the S-polarized light reflective layer is disposed on the fourth surface 132.

[0053] In some embodiments, the functional reflective element 20 may be a mirror ink layer, which is used to increase the reflectivity of the display area to the projection light 301, such that the reflectivity of the display area to the projection light 301 is greater than or equal to 8%. The visible light transmittance of the mirror ink layer is less than or equal to 5%, and specific examples include 5%, 4%, 3%, 2%, 1%, and 0%. This allows the mirror ink layer to serve as part of the bottom shielding area 1021. The mirror ink layer may be disposed on the second surface 112, or between the second surface 112 and the third surface 131, or on the third surface 131, or on the fourth surface 132. Preferably, the surface roughness Ra of the mirror ink layer is less than or equal to 0.1 μm, more preferably less than or equal to 0.05 μm, and even more preferably less than or equal to 0.025 μm.

[0054] In some embodiments, the bottom shielding area 1021 is selected from at least one of a dark ink layer, an opaque polymer film, a dimming film, and a functional reflective element with a visible light transmittance of less than or equal to 5%. The dark ink layer can form the bottom shielding area 1021 alone or in combination with an opaque polymer film, a dimming film, or a functional reflective element to form the bottom shielding area 1021. The opaque polymer film can form the bottom shielding area 1021 alone or in combination with a dark ink layer, a dimming film, or a functional reflective element to form the bottom shielding area 1021. The dimming film is preferably combined with a dark ink layer or an opaque polymer film to form the bottom shielding area 1021. The functional reflective element with a visible light transmittance of less than or equal to 5% is preferably combined with a dark ink layer or an opaque polymer film to form the bottom shielding area 1021. The bottom shielding area 1021 can be flexibly adjusted and set according to actual needs. The bottom shielding area 1021 can be used as a display background for the displayed image, so that the displayed image is not affected by the brightness of the external environment of the vehicle, thereby improving the display effect of the functional reflective element 20.

[0055] The opaque polymer film may be a body-colored polymer film, for example, by adding a black or brown coloring component during the manufacturing process; a surface-printed polymer film with ink or pigment, for example, by printing black ink or brown pigment on the surface of the polymer film; or a dyed or colored polymer film, for example, by coloring the polymer film with a black or brown dye. The polymer film may be made of polyvinyl butyral (PVB), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), polymethyl methacrylate (PMMA), etc. Preferably, the opaque polymer film has a thickness of less than or equal to 0.3 mm, and specifically, may be 0.3 mm, 0.25 mm, 0.2 mm, 0.15 mm, 0.1 mm, 0.08 mm, 0.05 mm, 0.02 mm, etc., so that the opaque polymer film has a minimal impact on the overall thickness of the laminated glass structure. More preferably, the opaque polymer film has a thickness of less than or equal to 0.1 mm, and even more preferably, less than or equal to 0.05 mm.

[0056] The dimming film can be a polymer dispersed liquid crystal film (PDLC), a suspended particle film (SPD), an electrochromic film (EC), a dye liquid crystal film (LC), etc. The minimum visible light transmittance of the dimming film is less than or equal to 5%, such as 3%, 2%, 1%, 0.5%, or 0%. In addition, the maximum visible light transmittance of the dimming film can be set as needed, such as 10%, 20%, 30%, 50%, 70%, or 80%. Specifically, the visible light transmittance of the dimming film can be adjusted between 0% and 20%, between 0.5% and 50%, or between 0% and 70%. The dimming film can meet the visible light transmittance requirements of multiple scenarios. For example, when black border display is required, the dimming film is in an opaque state (visible light transmittance is less than or equal to 5%, or even 0%), improving the contrast between the displayed image and the display background. When no display is required, the dimming film is in a transparent state (visible light transmittance is greater than or equal to 70%), achieving transparency in a larger area of ​​the glass body 10.

[0057] Among them, the functional reflective element with a visible light transmittance less than or equal to 5% can also serve as a part of the bottom shielding area 1021 while realizing image display, which is more conducive to the combined design of the bottom shielding area 1021 and the functional reflective element.

[0058] In Figure 2, the bottom shielding area 1021 is a dark ink layer 14 disposed on the second surface 112. The functional reflective element 20 is disposed on the third surface 131. The projection of the dark ink layer 14 on the third surface 131 completely covers the functional reflective element 20. When the functional reflective element 20 displays an image, the dark ink layer 14 serves as the display background of the displayed image, effectively shielding the external ambient light and preventing unnecessary interference to the line of sight. It also makes the image display clearer and achieves a higher contrast and color gamut.

[0059] As shown in Figure 3, the bottom shielding area 1021 is a dark ink layer 14 disposed on the third surface 131. The functional reflective element 20 is disposed on the fourth surface 132. The projection of the dark ink layer 14 on the fourth surface 132 completely covers the functional reflective element 20. When the functional reflective element 20 displays an image, the dark ink layer 14 serves as the display background of the displayed image, which can better block external ambient light, avoid unnecessary interference with the line of sight, and make the image display clearer, achieving a higher contrast and color gamut.

[0060] As shown in FIG4 , the bottom shielding area 1021 is a dark ink layer 14 disposed on the fourth surface 132. The functional reflective element 20 is disposed on the dark ink layer 14, and the dark ink layer 14 completely covers the projection of the functional reflective element 20 on the fourth surface 132. When the functional reflective element 20 displays an image, the dark ink layer 14 serves as the display background of the displayed image, which can better block external ambient light, avoid unnecessary interference with the line of sight, and make the image display clearer, achieving a higher contrast and color gamut.

[0061] As shown in Figure 5, the bottom shielding area 1021 is a combination of a dark ink layer 14 and a functional reflective element 20 with a visible light transmittance of less than or equal to 5%. The dark ink layer 14 is disposed on the second surface 112, while the functional reflective element 20 with a visible light transmittance of less than or equal to 5% is disposed on the third surface 131. The dark ink layer 14 has a hollow area 141, which partially overlaps with the functional reflective element 20. The area of ​​the functional reflective element 20 is larger than that of the hollow area 141. The functional reflective element 20 can both display images and serve as a partial background for the displayed image. The dark ink layer 14 serves as another partial background for the displayed image, further facilitating the design of the combination of the bottom shielding area 1021 and the functional reflective element. Furthermore, the use of the dark ink layer 14 in the bottom shielding area 1021 is reduced, further reducing the difficulty of the printing process and improving the bending quality of the outer glass sheet 11.

[0062] As shown in Figure 6, the bottom shielding area 1021 comprises a combination of a dark ink layer 14 and a functional reflective element 20 with a visible light transmittance of less than or equal to 5%. Both the dark ink layer 14 and the functional reflective element 20 are disposed simultaneously on the second surface 112. The dark ink layer 14 includes a hollowed-out area 141, within which the functional reflective element 20 is positioned. The functional reflective element 20 can both display images and serve as a background for these images. The dark ink layer 14 shields the functional reflective element 20, further facilitating the combined design of the bottom shielding area 1021 and the functional reflective element. Furthermore, the use of the dark ink layer 14 in the bottom shielding area 1021 is reduced, further reducing the complexity of the printing process and improving the bending quality of the outer glass sheet 11. It is understood that the dark ink layer 14 and the functional reflective element 20 can also be disposed simultaneously on the third surface 131 or the fourth surface 132.

[0063] As shown in FIG7 , the bottom shielding area 1021 is a combination of a dark ink layer 14 and an opaque polymer film 15. The dark ink layer 14 is disposed on the second surface 112, the opaque polymer film 15 is disposed in the adhesive layer 12, and the functional reflective element 20 is disposed on the third surface 131. The dark ink layer 14 has a hollow area 141. The opaque polymer film 15 partially overlaps with the functional reflective element 20, and the area of ​​the opaque polymer film 15 is larger than the area of ​​the hollow area 141. The projection of the combination of the dark ink layer 14 and the opaque polymer film 15 on the third surface 131 completely covers the functional reflective element 20. When the functional reflective element 20 displays an image, the dark ink layer 14 and the opaque polymer film or the dimming film 15 together serve as the display background of the displayed image, effectively blocking ambient light and preventing unnecessary interference with vision. This also makes the image display clearer and achieves a higher contrast and color gamut. Moreover, the use of the dark ink layer 14 in the bottom shielding area 1021 is reduced, further reducing the difficulty of the printing process and improving the bending quality of the outer glass plate 11. Preferably, the area of ​​the opaque polymer film 15 is larger than the area of ​​the dark ink layer 14 in the bottom shielding area 1021.

[0064] As shown in FIG8 , the bottom shielding area 1021 is a combination of a dark ink layer 14 and a dimming film 16. The dark ink layer 14 is disposed on the second surface 112, the dimming film 16 and the functional reflective element 20 are disposed in the adhesive layer 12, and the functional reflective element 20 is located between the dimming film 16 and the third surface 131. At least a portion of the dark ink layer 14 overlaps with the dimming film 16. The projection of the combination of the dark ink layer 14 and the dimming film 16 on the third surface 131 completely covers the projection of the functional reflective element 20 on the third surface 131. When the functional reflective element 20 is displaying an image, the visible light transmittance of the dimming film 16 is less than or equal to 5%, or even 0%. The dark ink layer 14 and the dimming film 16 together serve as the display background for the displayed image, effectively blocking ambient light and preventing unnecessary visual interference. This also allows for clearer images and higher contrast and color gamut. When the functional reflective element 20 is not displaying an image, the visible light transmittance of the dimming film 16 is greater than 5%, preferably greater than or equal to 10%, more preferably greater than or equal to 20%, and even more preferably greater than or equal to 50%, or even greater than or equal to 70%. This allows for a larger area of ​​the glass body 10 to be transparent, providing a wider field of view for vehicle occupants. Furthermore, the use of the dark ink layer 14 in the bottom shielding area 1021 is reduced, further reducing the difficulty of the printing process and improving the bending quality of the outer glass sheet 11. Preferably, the area of ​​the dimming film 16 is larger than the area of ​​the dark ink layer 14 in the bottom shielding area 1021.

[0065] The present application also provides a vehicle, which includes an image generation unit 30 and a black-border display window of any of the above embodiments. The image generation unit 30 projects the projection light 301 at an incident angle of 40° to 85° to the display area in the bottom shielding area 1021, and the display area reflects the incident projection light 301 into the eyes of the people in the vehicle to form a display image.

[0066] When the black-bordered display window is installed on a vehicle, it is preferably used as the front windshield of the vehicle. However, the black-bordered display window can also be used as the rear windshield or side window glass, thereby providing more display scene applications for the vehicle.

[0067] The vehicles in this application may be, but are not limited to, sedans, multi-purpose vehicles (MPVs), sport / suburban utility vehicles (SUVs), off-road vehicles (ORVs), pickup trucks, vans, buses, and trucks.
