Description

Technical Field

[0001] This invention belongs to the field of automobile manufacturing technology, and specifically relates to a B-pillar structure, a vehicle body structure including the B-pillar structure, and an automobile. Background Technology

[0002] In traditional automobile body structures, there are usually A-pillars, B-pillars, and C-pillars. Among them, the B-pillar often only has the traditional functions of supporting the roof and protecting the safety of occupants in side impacts. Currently, many patents mainly address the above-mentioned traditional functions by proposing improvements to the strength and stiffness of the B-pillar. For example, patent CN113291381A discloses an automobile B-pillar reinforcement structure and an automobile B-pillar, including an automobile B-pillar reinforcement structure, an inner B-pillar panel (6), and an outer B-pillar panel. By setting up a B-pillar reinforcement structure, the overall strength and stiffness of the B-pillar are improved, thereby enhancing the support and collision protection capabilities. However, with the development of automobile intelligence, the B-pillar's traditional functions of only providing support and collision protection can no longer meet the user's driving experience and prevent automobile companies from having a better competitive edge.

[0003] Therefore, the existing B-pillar of automobiles suffers from technical problems such as limited functionality and poor user experience. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of limited functionality and poor user driving experience associated with the existing B-pillar in automobiles.

[0005] To address the aforementioned technical problems, this invention discloses a B-pillar structure, comprising: a B-pillar body and a lamp module. The B-pillar body includes a transparent outer panel and an inner panel, which are fixedly connected to form a first hollow structure. An ink layer assembly is disposed on the outer surface of the transparent outer panel near the inner panel. The ink layer assembly comprises multiple ink layers stacked along the thickness direction of the transparent outer panel. Among the multiple ink layers, the ink layer closest to the transparent outer panel is a high-temperature black solid ink layer and has a first through-hole. The ink layer furthest from the transparent outer panel is a low-temperature black light-transmitting ink layer, covering the area surrounding the first through-hole of the high-temperature black solid ink layer. The lamp module is fixedly disposed within the first hollow structure and corresponds to the first through-hole. When the lamp module is lit, a first light-transmitting area with the same shape and size as the first through-hole is formed on the side of the transparent outer panel furthest from the inner panel.

[0006] Using the above technical solution, the transparent outer panel and inner panel of the B-pillar structure are fixedly connected to form a first hollow structure, and the lamp assembly module of the B-pillar structure is fixedly installed in the first hollow structure. Multiple layers of ink are provided on the outer surface of the transparent outer panel near the inner panel. The ink layer closest to the transparent outer panel is a high-temperature black solid ink layer and has a first through-hole. The lamp assembly module is positioned corresponding to the first through-hole. The ink layer furthest from the transparent outer panel is a low-temperature black translucent ink layer and covers the area surrounding the first through-hole of the high-temperature black solid ink layer. Because the high-temperature black solid ink layer is opaque and always appears black, while the low-temperature black translucent ink layer has a certain degree of translucency, it transmits light when illuminated and appears essentially black when not illuminated. When the light module of the B-pillar structure is lit, a first translucent area with the same shape and size as the first through hole can be formed on the side of the transparent outer panel away from the inner panel. The first translucent area has a preset light transmission effect (the shape of the first through hole), which can be used in scenarios such as welcoming guests and bidding farewell, improving the user's driving experience. When the light module of the B-pillar structure is not lit, the first translucent area displays the color of the low-temperature black translucent ink layer, and the B-pillar structure presents a unified black effect, giving it a sense of wholeness.

[0007] According to another specific embodiment of the present invention, the B-pillar structure disclosed in this embodiment includes a multi-layer ink layer comprising a first ink layer, a second ink layer, and a third ink layer sequentially disposed thereon. The first ink layer is the ink layer closest to the transparent outer plate among the multi-layer ink layers, and the third ink layer is the ink layer furthest from the transparent outer plate among the multi-layer ink layers. Furthermore, the second ink layer is a high-temperature gray solid ink layer and includes a first region of the second ink layer, which covers the area surrounding the first through-hole of the first ink layer and has a second through-hole corresponding to the first through-hole. The second through-hole has the same shape and size as the first through-hole. The third ink layer covers the area surrounding the second through-hole of the second ink layer, and the boundary of the third ink layer is located inside the boundary of the second ink layer.

[0008] By adopting the above technical solution, since the high-temperature gray solid ink layer is opaque and always displays gray, the high-temperature gray solid ink layer covers the area around the first through hole of the first ink layer, i.e., the high-temperature black solid ink layer, and the boundary of the third ink layer, i.e., the low-temperature black light-transmitting ink layer, is located inside its boundary. This achieves a second coverage effect around the area around the first through hole, avoiding the halo effect that occurs around the first light-transmitting area, which has the same shape and size as the first through hole, on the side of the transparent outer plate away from the inner plate after the lamp module is lit, thus ensuring a better display effect for the first light-transmitting area.

[0009] According to another specific embodiment of the present invention, in the B-pillar structure disclosed in this embodiment, the light transmittance of the third ink layer ranges from 5% to 7%.

[0010] Using the above technical solution, the light transmittance of the third ink layer, namely the low-temperature black translucent ink layer, ranges from 5% to 7%, ensuring that it has a certain degree of light transmittance while maintaining a good black appearance visually.

[0011] According to another specific embodiment of the present invention, the B-pillar structure disclosed in this embodiment of the present invention has a third through hole in the first ink layer to form a second light-transmitting area with the same shape and size as the third through hole on the side of the transparent outer plate away from the inner plate; and the B-pillar structure also includes a camera, the transparent outer plate and the inner plate are fixedly connected to form a second hollow structure, the camera is disposed in the second hollow structure, corresponding to the third through hole, and is fixedly and sealed to the transparent outer plate and the inner plate respectively.

[0012] By adopting the above technical solution, a camera is installed on the B-pillar structure to collect information about the vehicle's surroundings. After processing, this information provides various ADAS driving assistance functions such as adaptive cruise control, lane departure warning, collision warning, and automatic parking, further expanding the functions of the B-pillar system and improving the user experience.

[0013] According to another specific embodiment of the present invention, the B-pillar structure disclosed in this embodiment of the present invention has a first ink layer with a fourth through hole; the second ink layer further includes a second ink layer second region, which covers the area surrounding the fourth through hole of the first ink layer; the B-pillar structure also includes an NFC module, a transparent outer plate and an inner plate are fixedly connected to form a third hollow structure, the NFC module is fixedly disposed in the third hollow structure and is disposed corresponding to the fourth through hole, so as to form an NFC identification area with the same shape and size as the fourth through hole on the side of the transparent outer plate away from the inner plate.

[0014] Using the above technical solution, the B-pillar structure also includes an NFC module, enabling vehicle unlocking, starting, and locking functions, thus increasing the functionality of the B-pillar structure and further improving the user experience. Furthermore, the NFC module is fixedly installed in the third hollow structure. The first ink layer has a fourth through-hole, and the second area of ​​the second ink layer covers the area surrounding the fourth through-hole in the first ink layer. The NFC module is positioned corresponding to the fourth through-hole, forming an NFC identification area on the side of the transparent outer panel away from the inner panel, with the same shape and size as the fourth through-hole. The NFC identification area is always gray, providing an indicative effect without being overly obtrusive.

[0015] According to another specific embodiment of the present invention, the B-pillar structure disclosed in the present invention has a first light-transmitting area in the shape of a preset pattern.

[0016] By adopting the above technical solution, the first light-transmitting area presents a preset pattern shape, which improves the user experience.

[0017] According to another specific embodiment of the present invention, the B-pillar structure disclosed in this embodiment includes a lamp module comprising an upper cover, a brightness enhancement film assembly, a light guide plate, a reflective film assembly, a lamp panel, a lower cover, and a breathable membrane; the upper cover and the lower cover are fixedly connected to form a fourth hollow structure; the brightness enhancement film assembly, the light guide plate, the reflective film assembly, and the lamp panel are fixedly disposed inside the fourth hollow structure; the breathable membrane is fixedly disposed on the lower cover; the lower cover is fixedly connected to the inner panel, and the upper cover is fixedly and sealed to the transparent outer panel.

[0018] Using the above technical solution, the light panel can achieve uniform light emission through the micro-pattern of the light guide plate, improve brightness by superimposing a brightness enhancement film group on the light guide plate, and allow internal water vapor to be discharged through the breathable membrane.

[0019] According to another specific embodiment of the present invention, the thickness of the lamp module in the B-pillar structure disclosed in this embodiment is 15-16 mm.

[0020] Using the above technical solution, the thickness of the lamp module is 15-16mm, which is relatively small and ensures that the thickness of the B-pillar structure is not too thick, thus guaranteeing the side impact protection function of the B-pillar structure.

[0021] The present invention also discloses a vehicle body structure, including a body sheet metal structure and the aforementioned B-pillar structure, wherein the B-pillar structure is detachably and sealedly connected to the body sheet metal structure.

[0022] By adopting the above technical solution, the vehicle body structure, including the aforementioned B-pillar structure, enhances the user experience of the vehicle body structure. The B-pillar structure is detachably and sealed to the body sheet metal structure, which not only prevents liquids and dust from entering and improves durability, but also facilitates convenient and quick replacement and installation when parts in the B-pillar structure are damaged.

[0023] The present invention also discloses an automobile, including the above-described body structure.

[0024] By adopting the above technical solutions, the user experience can be improved while maintaining a sense of overall cohesion, thereby enhancing the competitiveness of automobile companies. Attached Figure Description

Detailed Implementation

[0042] In traditional automobile body structures, there are usually A-pillars, B-pillars, and C-pillars. Among them, the B-pillar often only has the traditional functions of supporting the roof and protecting the safety of occupants in side impacts. Currently, many patents mainly address the above-mentioned traditional functions by proposing improvements to the strength and stiffness of the B-pillar. For example, patent CN113291381A discloses an automobile B-pillar reinforcement structure and automobile B-pillar, including an automobile B-pillar reinforcement structure, an inner B-pillar panel (6), and an outer B-pillar panel. By setting up a B-pillar reinforcement structure, the overall strength and stiffness of the B-pillar are improved, thereby enhancing the support and anti-collision capabilities. However, with the development of automobile intelligence, the B-pillar's traditional functions of only providing support and anti-collision are no longer sufficient to meet the user's driving experience and prevent automobile companies from having a better competitive edge. Therefore, the existing automobile B-pillars suffer from the technical problems of limited functionality and poor user experience.

[0043] To address the aforementioned problems of the prior art, this invention provides a B-pillar structure, comprising a transparent outer panel and an inner panel, with a light module arranged between them. The outer panel, near the inner panel, has at least two ink layers. The layer closest to the outer panel is a high-temperature black solid ink, which is opaque and always appears black, with a customizable perforated pattern corresponding to the light module. The layer furthest from the outer panel is a low-temperature black translucent ink, which has some translucency and appears essentially black when not illuminated. When the light module is lit, light passes through the low-temperature black translucent ink, illuminating the perforated pattern, which is used in welcoming and farewell scenarios, enhancing the user experience. When the light module is not lit, the B-pillar structure presents a unified black effect, creating a cohesive look.

[0044] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] To address the above problems, this invention provides a B-pillar structure, such as... Figure 1-3 As shown, it includes: a B-pillar body and a light assembly module 50. The B-pillar body includes a transparent outer panel 10 and an inner panel 20, which are fixedly connected to form a first hollow structure.

[0047] Specifically, in this embodiment, the transparent outer panel 10 can be made of 3.2mm thick tempered white glass, and the inner panel 20 can be made of ABS engineering plastic. The transparent outer panel 10 and the inner panel 20 can be fixedly connected by adhesive, and the adhesive used for bonding can be structural adhesive 30.

[0048] An ink layer assembly is provided on the outer surface of the transparent outer panel 10 near the inner panel 20. The ink layer assembly includes multiple ink layers stacked along the thickness direction of the transparent outer panel 10; wherein, for example... Figures 4-6 As shown, in multiple ink layers, as Figure 4 As shown, the closest to the transparent outer panel 10 ( Figure 4-6 The ink layer (not shown) is a high-temperature black solid ink layer 41, and is provided with a first through hole 411, such as... Figure 6 As shown, the ink layer furthest from the transparent outer panel 10 is a low-temperature black translucent ink layer 43, which covers the area surrounding the first through-hole 411 of the high-temperature black solid ink layer 41. The lamp module 50 is fixedly disposed in the first hollow structure and is disposed corresponding to the first through-hole 411; after the lamp module 50 is lit, a first light-transmitting area 11 with the same shape and size as the first through-hole 411 can be formed on the side of the transparent outer panel 10 away from the inner panel 20.

[0049] Specifically, such as Figure 8 As shown, the lamp module 50 can be positioned by locating pins and fixed to the inner plate 20 by self-tapping screws.

[0050] It should be noted that the boundary of the high-temperature black solid ink layer 41 coincides with the boundary of the transparent outer panel 10. The specific shape of the first through-hole 411 of the high-temperature black solid ink layer 41 can be set by those skilled in the art according to the desired effect. In one specific embodiment, the first light-transmitting area 11 has a preset pattern shape. That is, the first through-hole 411 is set to a preset pattern shape, which can be a car logo, a company logo, a welcome message shape, or other specific pattern shapes.

[0051] Specifically, the low-temperature black light-transmitting ink layer 43, which is furthest from the transparent outer panel 10, covers the area around the first through hole 411 of the high-temperature black solid ink layer 41, which is closest to the transparent outer panel 10. The lamp module 50 is fixedly installed in the first hollow structure formed after the transparent outer panel 10 and the inner panel 20 are fixedly connected and is set corresponding to the first through hole 411. Because the high-temperature black solid ink layer is opaque and always appears black, while the low-temperature black translucent ink layer 43 has a certain degree of translucency, it is translucent when illuminated and basically appears black when not illuminated. When the light module 50 of the B-pillar structure is lit, a first translucent area 11 with the same shape and size as the first through hole 411 can be formed on the side of the transparent outer panel 10 away from the inner panel 20. The first translucent area 11 has a preset translucent effect (the shape of the first through hole 411) and can be used for welcoming guests, bidding farewell, and other scenarios, improving the user's driving experience. When the light module 50 of the B-pillar structure is not lit, the first translucent area 11 displays the color of the low-temperature black translucent ink layer 43, which is black, and the B-pillar structure presents a one-piece black effect, which has a sense of unity.

[0052] In one embodiment of the present invention, the multilayer ink layer group includes a first ink layer 41, a second ink layer 42, and a third ink layer 43 sequentially disposed, such as... Figure 4-6 As shown, Figure 4 This is a schematic diagram of the structure of the first ink layer 41. Figure 5 This is a schematic diagram of the structure of the first ink layer 41 and the second ink layer 42. Figure 6 This is a schematic diagram of the structure of the first ink layer 41, the second ink layer 42, and the third ink layer 43. The first ink layer 41 is the ink layer closest to the transparent outer plate 10 in the multilayer ink layers (i.e., the high-temperature black solid ink layer 41), and the third ink layer 43 is the ink layer furthest from the transparent outer plate 10 in the multilayer ink layers (i.e., the low-temperature black light-transmitting ink layer 43). The second ink layer 42 is a high-temperature gray solid ink layer 42 and includes a first region 421 of the second ink layer. The first region 421 of the second ink layer covers the area surrounding the first through hole 411 of the first ink layer 41 and is provided with a second through hole 4211 corresponding to the first through hole 411. The second through hole 4211 has the same shape and size as the first through hole 411. The third ink layer 43 covers the area surrounding the second through hole 4211 of the second ink layer 42, and the boundary of the third ink layer 43 is located inside the boundary of the second ink layer 42.

[0053] Specifically, in this embodiment, the second ink layer 42 may also be a high-temperature solid ink layer of other colors, such as blue, brown, etc.

[0054] It should be noted that, in this embodiment, when printing the multi-layer ink layers of the transparent outer panel 10, the first ink layer 41 is printed first, then the second ink layer 42 is printed, and finally the third ink layer 43 is printed.

[0055] More specifically, since the second ink layer (i.e., the high-temperature gray solid ink layer) 42 is opaque and always displays gray, the second ink layer 42 is set to cover the area around the first through hole 411 of the first ink layer (i.e., the high-temperature black solid ink layer) 41. Specifically, the boundary between the second ink layer 42 and the first ink layer 41 can be 1mm apart, with the tolerance controlled within ±0.5mm. The boundary of the third ink layer (i.e., the low-temperature black light-transmitting ink layer) 43 is located inside its boundary, which can achieve a second coverage effect around the area around the first through hole 411. This avoids the halo effect around the first light-transmitting area 11, which is the same shape and size as the first through hole 411, formed on the side of the transparent outer plate 10 away from the inner plate 20 after the lamp module 50 is lit, ensuring a better display effect for the first light-transmitting area 11.

[0056] In one embodiment of the present invention, the light transmittance of the third ink layer 43 is in the range of 5% to 7%. This low light transmittance ensures that the third ink layer 43 has a certain degree of light transmittance while maintaining a good black appearance.

[0057] In one embodiment of the present invention, such as Figure 7-9 As shown, the lamp module 50 includes an upper cover 51, a brightness enhancement film assembly, a light guide plate 53, a reflective film assembly, a lamp panel 55, a lower cover 56, and a breathable membrane 57; the upper cover 51 and the lower cover 56 are fixedly connected to form a fourth hollow structure; the brightness enhancement film assembly, the light guide plate 53, the reflective film assembly, and the lamp panel 55 are fixedly disposed inside the fourth hollow structure; the breathable membrane 57 is fixedly disposed on the lower cover 56; the lower cover 56 is fixedly connected to the inner plate 20, and the upper cover 51 is fixedly and sealed to the transparent outer plate 10.

[0058] Specifically, the brightness enhancement film assembly includes a first brightness enhancement film 521 and a second brightness enhancement film 522, which are a 0° brightness enhancement film and a 90° brightness enhancement film, respectively. The lamp board 55 integrates LED lights, heat sinks, wiring harnesses, etc., and is assembled to the lower cover 56 through its groove and upper limit rib. The reflective film assembly includes a first reflective film 541 and a second reflective film 542. The second reflective film 542 is pasted on the outer ring of the light guide plate 53. The first reflective film 541, the light guide plate 53 integrating the second reflective film 542, the first brightness enhancement film 521, and the second brightness enhancement film 522 are sequentially placed on the lamp board 55, and the above components are locked and fixed to the lower cover 56 by two screws. Its optical principle mainly involves LED lights achieving uniform light emission through the micro-pattern of the light guide plate 53. Brightness is enhanced by superimposing brightness-enhancing films at 0° and 90° on the upper side of the light guide plate 53, achieving a brightness increase of up to 15%. Simultaneously, the first reflective film 541 on the lower side of the light guide plate 53 and the surrounding second reflective film 542 ensure uniform light emission within a large 80° range to the left and right. The upper cover 51 and lower cover 56 are fixed by ultrasonic welding, and the lower cover 56 and wiring harness are sealed with sealant to achieve an IP67 self-sealing rating. Furthermore, the lamp module 50 and the transparent outer plate 10 are sealed together by a sealing gasket 58, which can be attached to the upper cover 51 with adhesive. A breathable membrane 57 is attached to the back of the lower cover 56 to allow internal water vapor to escape. The transparent outer plate 10 and inner plate 20 around the lamp module 50 are sealed together, specifically using PU adhesive.

[0059] It should be noted that, in order to reduce costs, in this embodiment, the lamp module 50 can be directly controlled by the vehicle body electronic control. The Body Control Module (BCM) uses hard-wired direct drive to control whether the lights are on or off. This is done when a user enters the vehicle. The light module 50 illuminates when the vehicle is unlocked, the key is within 5 meters of the vehicle, or the door is opened. It also illuminates when the user leaves the vehicle and opens the door. This is used in welcoming and farewell scenarios to enhance the sense of occasion and increase brand awareness.

[0060] In one embodiment of the present invention, the thickness of the lamp module 50 is 15-16 mm. Traditional lamp bodies require a thickness of 25 mm or more. Since the Y-axis space in the B-pillar area is relatively small, excessively thick lamp bodies can negatively impact the vehicle's collision performance. By using the lamp module 50 described above, the thickness of the entire lamp module 50 is reduced to less than 16 mm, ensuring that the B-pillar structure is not excessively thick and thus guaranteeing its side-impact protection function.

[0061] It should be noted that in this embodiment, the light transmittance of the third ink layer 43 and the number of LEDs in the lamp module 50 can be adjusted according to the brightness requirements after lighting. For example, if the brightness requirement after lighting is ≥1000nt through the B-pillar, and to achieve the effect of making the integrated black pattern invisible, the transmittance of the low-temperature light-transmitting ink is defined as 6%, then 6 LEDs are arranged in the lamp module 50, and the brightness requirement of the lamp group is ≥17000nt.

[0062] Pattern display is generally defined as emitting white light, and the range of white light color coordinates is shown in Table 1 below.

[0063] Table 1. Range of Standard Color Coordinates for White Light

[0064]

[0065] The standard requires a wide range of white light color coordinates. In terms of process, the desired white light appearance can be achieved by adjusting the color and proportion of varnish in the translucent ink. As shown in Table 2, by adding blue to the varnish and increasing the proportion of blue, the X and Y color coordinate values ​​can be reduced, resulting in a bluish white light, and vice versa.

[0068]

[0069]

[0070] In one embodiment of the present invention, such as Figure 4 As shown, the first ink layer 41 is provided with a third through hole 412 to form a second light-transmitting area on the side of the transparent outer plate 10 away from the inner plate 20, which has the same shape and size as the third through hole 412. Figure 2 As shown, the B-pillar structure also includes a camera 60, and the transparent outer panel 10 and inner panel 20 are fixedly connected to form a second hollow structure. The camera 60 is disposed in the second hollow structure, corresponding to the third through hole 412, and is fixedly and sealed to the transparent outer panel 10 and inner panel 20 respectively.

[0071] Specifically, such as Figure 10 and Figure 11 As shown, the camera 60 can be positioned by a locating pin and fastened to the inner panel 20 by self-tapping screws. Due to the high sealing requirements around the camera 60 (IP67 required) and to prevent fogging on the transparent outer panel 10 from affecting the camera 60's function, the transparent outer panel 10 and inner panel 20 around the camera 60 are sealed with PU adhesive. The camera 60 and inner panel 20 can be sealed with a rubber ring. To prevent fogging on the transparent outer panel 10, a breathable membrane needs to be designed near the camera 60, which can be specifically attached to the inner panel 20.

[0072] More specifically, a camera 60 is installed on the B-pillar structure to collect information about the vehicle's surroundings. After processing, this information provides various ADAS driving assistance functions such as adaptive cruise control, lane departure warning, collision warning, and automatic parking, further expanding the functionality of the B-pillar system and enhancing the user experience.

[0073] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the first ink layer 41 is provided with a fourth through hole 413; the second ink layer 42 further includes a second ink layer second region 422, which covers the area surrounding the fourth through hole 413 of the first ink layer 41. Figure 2 As shown, the B-pillar structure also includes an NFC module 70. The transparent outer panel 10 and the inner panel 20 are fixedly connected to form a third hollow structure. The NFC module 70 is fixedly disposed in the third hollow structure and is disposed corresponding to the fourth through hole 413, so as to form an NFC identification area 12 with the same shape and size as the fourth through hole 413 on the side of the transparent outer panel 10 away from the inner panel 20.

[0074] Specifically, in this embodiment, to save space, the NFC module 70 eliminates the outer casing and uses a bare PCB board on which electrical components are arranged. For example... Figures 12-14 As shown, the NFC module 70 is welded to the inner plate 20 using welding posts. To ensure the sealing performance of the area where the NFC module 70 is located, the transparent outer plate 10 around the perimeter of the NFC module 70 is sealed to the inner plate 20 with PU adhesive, and the back of the NFC module 70 is sealed with a wire harness plug.

[0075] More specifically, the B-pillar structure also includes an NFC module 70, which enables vehicle unlocking, starting, and locking functions, increasing the functionality of the B-pillar structure and further improving the user experience. Furthermore, the NFC module 70 is fixedly disposed in the first hollow structure. The first ink layer 41 has a fourth through-hole 413, and the second area 422 of the second ink layer covers the area surrounding the fourth through-hole 413 of the first ink layer 41. The NFC module 70 is correspondingly disposed to the fourth through-hole 413, forming an NFC identification area 12 on the side of the transparent outer panel 10 away from the inner panel 20, with the same shape and size as the fourth through-hole 413. The NFC identification area 12 is always the color of the second ink layer, i.e., gray, providing an indicative effect without being overly obtrusive.

[0076] It should be noted that in this embodiment, the NFC (Near Field Communication) function can be used to unlock, start, and lock the vehicle via a mobile phone or a physical NFC card. Its control principle is as follows: Figure 15As shown. In traditional solutions, the NFC reader is directly connected to the LIN (a serial communication method) channel of the vehicle's Body Control Module (BCM). When an NFC card approaches the NFC reader, the reader recognizes the card's presence and authenticates it. Then, it wakes up the BCM on the LIN channel and authenticates the card to initiate the unlocking function. In this implementation, the NFC reader is connected to the Bluetooth Controller Module (BPEPS). The BPEPS and the NFC reader interact via a proprietary CANFD (a serial communication method), handling the NFC's locking and unlocking logic, and then transmit the data to the BCM via CAN signals. When an NFC card or Apple phone is brought within 4cm of the NFC reader, the NFC reader's operating mode (NFCStatus) switches from Low Power CD (LPCD) to Polling mode (POLING). It actively polls to check the card's AID (Affiliate ID). If a positive response is received after sending the card's AID, the NFC reader periodically sends network management messages (Netwake messages) on the BPEPS's private CANFD to wake up the BPEPS, notifying it of an NFC physical card swipe event. After the BPEPS responds positively, it engages in authentication interaction with the NFC Reader on the CANFD (NFCKeyReq and NFCKeyResp). Upon successful interaction, the BPEPS is notified that an NFC card has been detected. The BPEPS then interacts with the BCM (Challenge and Response) to initiate the unlocking function. This solution supports the CCC protocol (used for communication between smartphones and vehicles), meets MFI certification (an Apple certification program that allows third-party accessory manufacturers to develop hardware products compatible with Apple devices), and supports Apple phone card swiping for unlocking and starting the vehicle.
