Description

Technical Field

[0001] This disclosure relates to a system for providing an alarm indicating that a vehicle seatbelt is not fastened, and more specifically, to a system for providing an alarm indicating that a vehicle seatbelt is not fastened, the system wirelessly identifying whether the seatbelt is fastened and outputting an alarm when the seatbelt is not fastened. Background Technology

[0002] Existing systems for providing warnings of unfastened seatbelts are typically wired to the front seats of a vehicle. Specifically, a seatbelt buckle warning device, or existing technology, is installed on the seat to detect, for example, the weight distribution of a person sitting in the seat and their electrical current, thereby detecting whether the seatbelt buckle is fastened. Thus, the device determines whether the seatbelt buckle is fastened based on the weight of a person or animal other than a non-conductive object, and provides a warning if it is not fastened.

[0003] However, when it is necessary to determine whether all seat belts are fastened, or when the seats move freely, causing spatial deformation, such as in autonomous vehicles, conventional systems that determine seat belt fastening via wired means may struggle to make such determinations based on wired processing. Therefore, there is a need to develop a system capable of wirelessly determining whether seat belts are fastened and providing notification of that determination. Summary of the Invention

[0004] This disclosure addresses the aforementioned problems and provides a system for providing an alarm indicating that a vehicle's seatbelts are not fastened, wherein the system wirelessly confirms whether the seatbelts of all seats in the vehicle are fastened, and provides an alarm if the seatbelts are not fastened.

[0005] A system according to this disclosure for providing an alarm indicating that a vehicle seatbelt is not fastened may include: a seatbelt portion disposed in a seat of a vehicle; a first controller communicatively connected to the seatbelt portion and configured to determine whether the buckle of the seatbelt portion is fastened; a first sensor module connected to the first controller, the first sensor module including a first transmitter configured to send a buckle fastening signal when the buckle is fastened; a second sensor module including a first receiver configured to receive the buckle fastening signal from the first sensor module; and a second controller communicatively connected to the second sensor module and configured to receive the buckle fastening signal and output an alarm regarding whether the seatbelt is fastened.

[0006] The system may further include: a seat rail on which a seat is mounted; and a channel portion disposed adjacent to the seat rail, the channel portion having a first sensor module and a second sensor module disposed therein, and having a channel shape.

[0007] The system may further include: a first connecting member disposed inside the channel portion, on which one of a first sensor module and a second sensor module is mounted; and a second connecting member, one side (e.g., a first side) of which is connectable to the seat frame, and the opposite side (e.g., a second side) of which is connectable to one side of the first connecting member through a slit in the channel portion. The first sensor module may further include a second receiver configured to receive a buckle fastening signal, and the second sensor module may further include a second transmitter configured to transmit the buckle fastening signal. The first transmitter and the second receiver may be arranged parallel to each other, and the first transmitter may be positioned closer to the outside of the first sensor module than the second receiver.

[0008] A partition wall can be provided between the first transmitter and the second receiver. The first transmitter and the second receiver can be positioned on the upper and lower sides, respectively. The second receiver can be configured to be surrounded by multiple first transmitters.

[0009] The system may further include: a third controller communicatively connected to the seatbelt portion and configured to determine whether the buckle of the seatbelt portion is fastened; a third sensor module connected to the third controller, the third sensor module including a third transmitter configured to send a buckle fastening signal when the buckle is fastened; and a fourth sensor module including a third receiver configured to receive the buckle fastening signal from the third sensor module.

[0010] The first sensor module and the fourth sensor module can be arranged parallel to each other inside the channel section, the second sensor module and the third sensor module can be arranged parallel to each other inside the channel section, the first sensor module and the second sensor module can face each other and be spaced apart from each other by a predetermined distance, and the third sensor module and the fourth sensor module can face each other and be spaced apart from each other by a predetermined distance.

[0011] The first and fourth sensor modules can be positioned on the upper and lower sides, respectively, as can the second and third sensor modules. The first and second sensor modules can face each other and be spaced apart by a predetermined distance, and the third and fourth sensor modules can also face each other and be spaced apart by a predetermined distance. The first and second sensor modules can be infrared sensors.

[0012] The system may also include an alarm unit configured to receive a buckle tightening signal from a second controller and output a notification indicating whether the seatbelt is tightened. The passageway portion may be located on the side surface of the seat rail and may be positioned adjacent to the seat rail. The passageway portion may be formed in a straight, curved, circular, or elliptical shape. The cross-section of the passageway portion may be polygonal or circular.

[0013] According to this disclosure, it is easier to confirm whether each of the seat belts is fastened, and even when the seat moves freely and thus deforms the space (as in the case of an autonomous vehicle), it is easier to confirm whether the seat belts are fastened and provide an alarm accordingly.

[0031] Hereinafter, a system for providing an alarm indicating that a vehicle seatbelt is not fastened will be described with reference to the accompanying drawings, according to an exemplary embodiment of the present disclosure.

[0032] refer to Figure 1 and Figure 2 A system for providing an alarm indicating that a vehicle seatbelt is not fastened, according to an exemplary embodiment of the present disclosure, may include a seatbelt section 100, a first controller 200, a first sensor module 300, a second sensor module 400, and a second controller 500, and may also include a seat rail 600, a passage section 700, a third sensor module 1100, a fourth sensor module 1200, a third controller 1000, and an alarm unit.

[0033] Seatbelt portion 100 is a seatbelt disposed in a vehicle seat, and may be a seatbelt disposed in multiple seats, wherein, according to an exemplary embodiment, these seats are located in the first and second rows of a vehicle including two rows of seats, such as... Figure 1 As shown. When several rows of seats are configured differently according to another exemplary embodiment, the seat belt portion 100 may be a seat belt disposed in the seat located in each row of seats.

[0034] The first controller 200 can be communicatively connected to the seat belt section 100 and can be configured to determine whether the buckle 110 of the seat belt section 100 is fastened. Specifically, the aspect in which the first controller 200 is communicatively connected to the seat belt section 100 may refer to the seat belt section 100 and the first controller 200 as follows: Figure 3 The parts shown are connected to each other via leads, and in response to determining that the buckle 110 of the seat belt portion 100 is fastened, a buckle fastening signal can be transmitted to a first controller 200. When the buckle fastening signal is transmitted to the first controller 200, the first controller 200 can be configured to determine that the buckle 110 of the seat belt portion 100 is fastened.

[0035] refer to Figure 3 and Figure 4 A first sensor module 300 may be connected to a first controller 200 and may be configured to send a buckle fastening signal in response to determining that the buckle 110 is fastened. According to an exemplary embodiment, the first sensor module 300 may include a first transmitter 310 configured to send the buckle fastening signal, and the first sensor module may also include a second receiver 320 configured to receive the buckle fastening signal. A second sensor module 400 may be configured to receive the buckle fastening signal from the first sensor module 300. According to an exemplary embodiment, the second sensor module 400 may include a first receiver configured to receive the buckle fastening signal, and the second sensor module may also include a second transmitter configured to send the buckle fastening signal.

[0036] Meanwhile, according to an exemplary embodiment, the first sensor module 300 and the second sensor module 400 can be infrared sensors. In this way, according to this disclosure, since infrared sensors can be used in both the first sensor module 300 and the second sensor module 400, a signal indicating whether the buckle 110 of the seatbelt portion 100 is fastened can be wirelessly transmitted and received. Furthermore, the signal can be transmitted and received wirelessly only when an event such as the buckle 110 being fastened occurs, such as a radio frequency identification (RFID) communication scheme or a Bluetooth Low Energy (BLE) scheme. This results in very low power consumption for the sensor modules, eliminates the need for complex fail-safe logic, and does not interfere with or hinder communication by other signals. The second controller 500 can be communicatively connected to the second sensor module 400 and can be configured to receive the buckle fastening signal and output an alarm indicating whether the seatbelt is fastened.

[0037] refer to Figure 3 In the description of the operating principle of a system for providing an alarm indicating that a vehicle seatbelt is not fastened according to an exemplary embodiment of the present disclosure, firstly, in response to determining that the buckle 110 of the seatbelt portion 100 is fastened, a buckle fastening signal of the seatbelt portion 100 can be transmitted to a first controller 200, which can be configured to operate the transmitter of a first sensor module 300 to transmit an infrared signal, a second sensor module 400 can be configured to receive the infrared signal via a first receiver, and a second controller 500 can be configured to transmit the buckle fastening signal to an external controller (not shown) so that an alarm unit outputs an alarm indicating that the seatbelt is not fastened.

[0038] The seat rail 600 is a rail on which a seat is mounted, and the seat can move forward or backward via the seat rail 600. According to an exemplary embodiment, the seat can rotate on the seat rail 600. According to an exemplary embodiment, as... Figure 5 As shown, the channel portion 700 can be connected to the seat rail 600 as a separate object from the seat rail 600. Specifically, the channel portion 700 can be located on the side surface of the seat rail 600 and can be disposed adjacent to the seat rail 600. According to another exemplary embodiment, the channel portion 700 can be integrally formed with the seat rail 600.

[0039] Furthermore, such as Figure 3 and Figure 4As shown, the first sensor module 300 and the second sensor module 400 can be disposed inside the channel portion 700. Furthermore, the channel portion 700 can have a channel shape to prevent the introduction of signals other than infrared signals, thereby improving the signal transmission / reception performance of the first sensor module 300 and the second sensor module 400. Typically, infrared sensors may experience data interference in environments with introduced light. To avoid this problem, according to this disclosure, by forming the channel portion 700, where the first sensor module 300 and the second sensor module 400 are disposed, into a tunnel shape to prevent the introduction of external signals, data interference and communication obstruction can be prevented.

[0040] refer to Figure 6 According to an exemplary embodiment, the channel portion 700 may have a straight, curved, circular, or elliptical shape, and the cross-section of the channel portion 700 may have a polygonal shape, including a triangular shape, a rectangular shape, and a circular shape. However, this is only an exemplary embodiment, and various other shapes may be used as the shape of the channel portion 700 of this disclosure, as long as it can prevent other external signals from being introduced into the channel portion 700.

[0041] In the following text, reference will be made to Figures 7 to 9 The first sensor module 300 is described in more detail. According to an exemplary embodiment, as... Figure 7 As shown, the first sensor module 300 may include a first transmitter 310 and a second receiver 320. The first transmitter is configured to transmit a buckle fastening signal, and the second receiver is configured to receive the buckle fastening signal. Specifically, as shown... Figure 7 As shown, the first transmitter 310 and the second receiver 320 can be arranged in parallel, and as... Figure 9 As shown, the first transmitter 310 can be positioned closer to the outside of the first sensor module 300 than the second receiver 320. Specifically, because the first transmitter 310 can be positioned closer to the outside of the first sensor module 300 than the second receiver 320, it is possible to prevent the signal transmitted by the first transmitter 310 from being received by the second receiver 320.

[0042] In addition, such as Figure 9 As shown, a partition wall 330 can be disposed between the first transmitter 310 and the second receiver 320 in the first sensor module 300. Specifically, the partition wall 330 can be disposed between the first transmitter 310 and the second receiver 320 to prevent signals transmitted by the first transmitter 310 from being received by the second receiver 320. Although not shown in the figures, according to another exemplary embodiment, the first sensor module 300 may only have a transmitter. Specifically, only one transmitter or multiple transmitters may be provided.

[0043] At the same time, refer to Figure 8 The first sensor module 300 can have a pair of first transmitters 310 and a second receiver 320 arranged in parallel on the left and right sides, or two pairs of first transmitters 310 and second receivers 320 arranged in parallel on the left and right sides, or a pair of first transmitters 310 and second receivers 320 arranged on the upper and lower sides, or two pairs of first transmitters 310 and second receivers 320 arranged on the upper and lower sides, with the second receiver 320 surrounded by multiple first transmitters 310. However, this is merely an example, and the number of transmitters and receivers in the first sensor module 300 and their arrangement can vary depending on the system's signal transmission / reception environment.

[0044] The third controller 1000 can be communicatively connected to the seatbelt portion 100 and can be configured to determine whether the buckle 110 of the seatbelt portion 100 is fastened. Specifically, the seatbelt portion 100 connected to the third controller 1000 can be provided in a seat located in a different row from the seat provided with the seatbelt portion 100 connected to the first controller 200. For example, in a vehicle with two rows of seats, the first controller 200 can be configured to determine whether the buckle 110 of the seatbelt portion 100 of the seat in the first row is fastened, and the third controller 1000 can be configured to determine whether the buckle 110 of the seatbelt portion 100 of the seat in the second row is fastened.

[0045] Furthermore, the aspect of the third controller 1000 being communicatively connected to the seat belt portion 100 can refer to the seat belt portion 100 and the third controller 1000 being connected to each other via leads, and in response to determining that the buckle 110 of the seat belt portion 100 is fastened, a buckle fastening signal can be transmitted to the third controller 1000. When the buckle fastening signal is transmitted to the third controller 1000, the third controller 1000 can be configured to determine that the buckle 110 of the seat belt portion 100 is fastened.

[0046] The third sensor module 1100 can be connected to the third controller 1000 and can be configured to send a buckle fastening signal when the buckle 110 is fastened. According to an exemplary embodiment, the third sensor module 1100 may include a third transmitter configured to send the buckle fastening signal, and the third sensor module may also include a fourth receiver configured to receive the buckle fastening signal. The fourth sensor module 1200 can be configured to receive the buckle fastening signal from the third sensor module 1100. According to an exemplary embodiment, the fourth sensor module 1200 may include a third receiver 1210 configured to receive the buckle fastening signal, and the fourth sensor module may also include a fourth transmitter 1220 configured to send the buckle fastening signal. The third sensor module 1100 and the fourth sensor module 1200 according to this disclosure can be infrared sensors, similar to the first sensor module 300 and the second sensor module 400.

[0047] At the same time, refer to Figure 10 and 11 The space utilization of the passageway 700 can be increased by placing sensor modules for two seats in different rows within a single passageway 700. Specifically, according to an exemplary embodiment, refer to... Figure 10 The first sensor module 300 and the fourth sensor module 1200 can be arranged parallel to each other inside the channel section 700. The second sensor module 400 and the third sensor module 1100 can be arranged parallel to each other inside the channel section 700. The first sensor module 300 and the second sensor module 400 can face each other and be spaced apart from each other at a predetermined distance. The third sensor module 1100 and the fourth sensor module 1200 can face each other and be spaced apart from each other at a predetermined distance.

[0048] In this way, the first sensor module 300 and the fourth sensor module 1200 can be arranged parallel to each other inside the channel portion 700, and the second sensor module 400 and the third sensor module 1100 can be arranged parallel to each other inside the channel portion 700, thereby preventing the signal sent by the first sensor module 300 from being interrupted by the fourth sensor module 1200, and preventing the signal sent by the third sensor module 1100 from being interrupted by the second sensor module 400.

[0049] According to another exemplary embodiment, reference Figure 11The first sensor module 300 and the fourth sensor module 1200 can be disposed on the upper side and the lower side, respectively. The second sensor module 400 and the third sensor module 1100 can be disposed on the upper side and the lower side, respectively. The first sensor module 300 and the second sensor module 400 can face each other and be spaced apart from each other at a predetermined distance. The third sensor module 1100 and the fourth sensor module 1200 can face each other and be spaced apart from each other at a predetermined distance.

[0050] In this way, the first sensor module 300 and the fourth sensor module 1200 can be positioned on the upper and lower sides, respectively, and the second sensor module 400 and the third sensor module 1100 can be positioned on the upper and lower sides, thereby preventing the signal sent by the first sensor module 300 from being interrupted by the fourth sensor module 1200, and preventing the signal sent by the third sensor module 1100 from being interrupted by the second sensor module 400.

[0051] At the same time, refer to Figure 12 A slit hole can be formed on the upper surface of one side of the passage portion 700 along the length direction of the passage portion 700. Furthermore, the system according to this disclosure for providing an alarm indicating that a vehicle seatbelt is not fastened may also include a first connecting member 800 and a second connecting member 900. The first connecting member is disposed inside the passage portion 700, and at least one of a first sensor module 300 or a second sensor module 400 can be mounted on the upper part of the first connecting member. One side or a first side of the second connecting member can be connected to the seat frame 810, and the opposite side or a second side of the second connecting member can be connected to one side of the first connecting member 800 through the slit hole in the passage portion 700.

[0052] Therefore, when the seat moves forward or backward via the first connecting member 800 and the second connecting member 900, the sensor module can also move along the slit hole in the passage portion 700 with the seat, thereby increasing the seat's freedom of movement. The alarm unit can be configured to receive a buckle tightening signal from the second controller 500 and output a notification regarding whether the seat belt is tightened. Furthermore, the alarm unit can be configured to receive a buckle tightening signal from a fourth controller and provide a notification indicating whether the seat belt is tightened. According to an exemplary embodiment, the alarm unit can be configured to output a notification to the driver regarding whether the seat belt is tightened via a dashboard, an audio-visual navigation (AVN) device, or a speaker. However, this is only an exemplary embodiment, and other configurations can also be used as the alarm unit of this disclosure, as long as they can transmit a buckle tightening signal from the fourth controller and provide a notification to the driver regarding whether the seat belt is tightened.
