[0013] The disclosed embodiments provide a luminous seat belt system, a vehicle and interior lighting control method, in which the vehicle's seat belts, seat belt buckles and seat interiors (seat upper surfaces) are all designed to be controllable and luminous, and can illuminate in dark conditions, making it easier for users to sit down and unfasten / fasten their seat belts. At the same time, the lighting state of the lighting structure of each part is controllable, and can change the lighting state according to the vehicle's operating state, thereby reducing or not emitting light when the vehicle is running, and avoiding the lighting affecting the driver's line of sight and thus affecting driving safety. At the same time, the seat belts, seat belt buckles and seat interiors are all designed to be luminous, and can illuminate at the same time, thereby avoiding the problem of dazzling seat belts when only the seat belts are illuminated but the seat interiors are not illuminated, and the large difference in brightness between the illuminated area of ​​the seat belt and the non-illuminated area of ​​the seat, making it more difficult for users to see the seat range, thereby improving the user experience.

[0014] Advantages of additional aspects of the present disclosure will be given in part in the following description, and in part will become apparent from the following description, or will be learned through practice of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the technical solutions in the embodiments of the present disclosure, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present disclosure. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0016] Figure 1 It is a schematic diagram of the overall structure of a luminous seat belt system provided by an embodiment of the present disclosure.

[0017] The accompanying drawings respectively represent: 1. seat belt buckle; 2. seat belt height adjuster; 3. seat belt; 4. seat. DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0019] The terms "first", "second", etc. in the specification, claims, and drawings of the present disclosure are used to distinguish different objects rather than to describe a specific order. Terms such as "upper", "lower", etc. that indicate orientation are described based on the positional relationship of each component structure under normal use. They are only used to describe relative positional relationships and do not necessarily indicate limitations on orientation. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products, or devices.

[0020] The present disclosure embodiment, such as Figure 1 As shown, firstly, a luminous seat belt system is provided, including a seat belt, a seat belt buckle and a seat interior, wherein the surfaces of the seat belt, the seat belt buckle and the seat interior are provided with electroluminescent materials, and the luminous state of the electroluminescent materials can be changed according to the change of input signals, and the input signals include the ambient light information in the vehicle, the door opening state, and the vehicle running state.

[0021] Existing seat belt webbing luminous and lock luminous technologies are all for the sub-components of the seat belt assembly to illuminate, and the seat belt buckle needs to be buckled to illuminate. The luminous area of ​​the buckle is not obvious, and the luminous belt itself is dazzling when driving in the dark, which can easily cause traffic accidents. It does not have an automatic control function, does not consider the vehicle environment, and is not effectively integrated with the vehicle operation status. Based on the above problems, this embodiment integrates the luminous seat belt, luminous lock and luminous seat, which has the following advantages:

[0022] In dim light conditions with the door open, the luminous seat belt system (buckle, webbing, lock tongue), seat fabric and guard plate all glow, giving customers a warm welcome feeling. This also avoids the situation where the light of a single seat belt causes the seat area to be less visible due to excessive contrast between the seat belt area and the seat area.

[0023] The luminous state of the luminous seat belt system can be adjusted autonomously according to the vehicle's operating status. The luminous brightness can be dimmed or turned off when the vehicle is running, thereby avoiding the light affecting the driver's field of vision during driving, or the reflection of the luminous structure on the front windshield affecting the driver's field of vision, thereby ensuring driving safety.

[0024] After wearing it, the customer can control and customize the lighting devices such as seat belt buckle, seat belt tongue, seat belt webbing, and seat fabric through voice control to prevent driving safety issues due to operating the control software while driving.

[0025] The customer's voice can customize the luminous color or the light can flash rhythmically with the vehicle's interior ambient light and music, with more than 256 colors adjustable.

[0026] In this embodiment, the seat belt 3 includes a seat belt webbing and a seat belt lock tongue. Preferably, both the seat belt webbing and the seat belt lock tongue are designed to be luminous. The purpose of increasing the luminescence of the lock tongue is to facilitate quick finding of the lock tongue in a dark environment to wear the seat belt, thereby improving wearing efficiency.

[0027] Seat belt webbing can be designed to be multi-color or monochromatic. For multi-color, it can be achieved by adding luminous silk threads during the weaving process, and the luminous color can be controlled by the size of the microcurrent. For monochromatic, yarn with fluorescent materials can be woven during the weaving process, which absorbs light from sunlight or lamps during the day and automatically emits light at night. In addition, the car company logo can be further designed on the webbing to emit light. The seat belt webbing can be powered by the fixed end, that is, the power supply of the seat belt webbing is fixed to the seat belt retractor through a connector and connected to the whole vehicle to realize the power supply of the luminous material on the webbing and the control of the luminous state. In some embodiments, for a multi-color luminous seat belt webbing, it can be designed that when the webbing power supply current is 1-10mA, the color of the luminous thread is red, the power supply current is 11-20mA is orange, the power supply current is 21-30mA is yellow, the power supply current is 31-4mA is green, the power supply current is 41-50mA is cyan, the power supply current is 51-60mA is blue, the power supply current is 61-70mA is purple, and the power supply current is 71-100mA is a rhythmic color. The rhythmic color can be further subdivided into different rhythms, such as different rhythmic frequencies, different colors, etc.

[0028] The seat belt lock tongue is illuminated by an LED lamp. An LED lamp can be designed at the lock tongue. The light emission is uniform through the surface light-transmitting material and the light-guiding structure. The built-in wireless connection can be used to connect to the vehicle's wireless device (such as Bluetooth, wireless WIFI) to control the lighting state. The power supply demand can be met by a built-in battery. The battery can also be charged when the lock tongue is inserted into the lock buckle.

[0029] The seat belt buckle 1 emits light by arranging an LED lamp tube, and the light emission is uniform through the light-transmitting material and the light-guiding structure. The LED lamp tube can be directly connected to the vehicle wiring harness to meet the power supply demand and realize the control of the light emission state.

[0030] The lighting of the seat 4 can be realized in two ways:

[0031] 1. Leather seats: LED light strips are embedded in the leather seat foam, and holes are punched in the seat fabric. Different types of light are formed by the size and pattern of the holes, and the seat control module is connected to the vehicle to meet the power supply and control requirements;

[0032] 2. The seat knitted fabric is made by weaving luminous yarn and controlling it through microcurrent to achieve luminescence. The luminescence principle is the same as that of the multi-color luminous seat belt webbing.

[0033] In addition, in some embodiments, the seat belt height adjuster 2 provided on the B-pillar of the vehicle can also be further designed as a luminous structure, and electroluminescent materials are added to improve the integrity of the interior when it is illuminated. The seat belt height adjuster is illuminated by pre-embedded LED lamps, and the wiring harness is connected to the vehicle wiring harness through a pre-installed guard plate to meet power supply and control requirements.

[0034] The embodiment of the present disclosure further provides a vehicle, which includes the luminous seat belt system provided above.

[0035] The vehicle includes a body control module, a domain controller module, a wiring harness or CAN, a seat, a microphone and other structures. The body control module and the microphone input signals through the wiring harness or CAN, the domain controller module performs signal judgment, and outputs signals to the luminous seat belt system (seat belts, seat belt buckles and seat interiors, etc.) through the wiring harness or CAN to realize lighting and control.

[0036] The logical judgment is as follows:

[0037] When the door is opened, the light at which position is lit is set by (which door is opened, which position is lit). By default, the seat belt webbing, lock tongue, lock buckle, and seat surface are lit (the default color is warm orange). After the passengers get on the car, the host starts, and the lighting position and color can be customized by voice control and the host large screen software (the color of the ambient light can be red, orange, yellow, green, cyan, blue, purple, white, and mixed colors of more than 256 colors). At the same time, if the owner allows the in-car camera to run, the in-car camera is used to identify adults or children, and the child seat wears a seat belt. The luminous color defaults to the standard soft light (using 2700K to 4000K warm white light, which can be calibrated) to ensure that it does not hurt the eyes. The luminous intensity can be preset to a fixed value, or it can be dynamically adjusted according to the actual ambient light. The light at the adult position can be slightly brighter. The main and co-driver can realize the memory function, and the default color is the owner's favorite color. Other passengers can set it through voice settings or APP software and in-car APP software (the number of memories is 100, and it is overwritten by default after exceeding). The light can be turned off by inserting the seat belt lock tongue into the buckle, or you can use voice control to light up your favorite parts.

[0038] After the driver starts the vehicle, all seat belt and seat system lights can be turned off or kept on synchronously.

[0039] When the vehicle is stationary and in the P gear, the lights will come on again to facilitate passengers to unlock the seat belts. When the seat belt buckle of the occupant is unlocked, the seat belt system and seat system lights will go out. When the vehicle is turned off, the lights will go out. If the vehicle is in N gear and the driver does not get off, other occupants will unlock the seat belts. When the occupant unlocks the seat belt buckle, the lights will go out.

[0040] The vehicle can also be further designed with control buttons connected to the controller of the photovoltaic power generation device. The control buttons can be mechanical buttons or virtual buttons integrated into the central control screen. When the host is started, the software can simultaneously set the rhythm of the luminous seat belts and seat lights and the instrument panel and door panel atmosphere lights to move with the host music and display different colors.

[0041] The embodiment of the present disclosure further provides an interior lighting control method, comprising:

[0042] Acquiring the ambient light information in the vehicle, equipped with an ambient light sensor, which can generate a first light emitting signal according to the ambient light information in the vehicle based on the light brightness;

[0043] Acquire the door opening state, and generate a second light emitting signal according to the door opening state (ON / OFF);

[0044] Acquire the vehicle operation state (ON / ACC / OFF), and generate a third light emitting signal according to the vehicle operation state;

[0045] In response to a user instruction, generating a fourth light emitting signal;

[0046] The lighting state and / or lighting intensity of the luminous seat belt system is controlled according to the first lighting signal, the second lighting signal, the third lighting signal and the fourth lighting signal.

[0047] Among them, the ambient light information in the vehicle can be obtained through the ambient light sensor installed in the vehicle. When it is determined that the light intensity in the vehicle is lower than the set threshold, for example, when the light intensity is lower than 10lux, a first light signal is generated. The first light signal can be used to trigger the main switch signal of the light-emitting seat belt system. When the first light signal is received, it can be further determined whether to emit light according to other signals. In addition, the first light signal can further include the luminous brightness of the light-emitting seat belt system controlled according to the ambient light information. The corresponding relationship between the luminous brightness and the ambient light information can be pre-calibrated. For example, the luminous intensity L of the controllable luminous material (LED light) installed at the seat belt buckle, seat belt tongue, seat, etc. is controlled according to the formula L=K·ln(L0-L1+1), where K is a proportional coefficient (calibrable), L0 is the ambient light intensity threshold, and L1 is the ambient light intensity.

[0048] The door opening status can be obtained based on the door sensor. When the door is detected to be open, a lighting control signal of the corresponding area can be generated according to the door opening position to control the lighting of the seat belt, lock and seat at the door.

[0049] The third luminous signal includes information such as the vehicle startup status, gear status, and vehicle speed. When the vehicle is not started, the light can be controlled. When the driver starts the vehicle, all the luminous structures can be extinguished at the same time to avoid affecting driving safety. The gear status is the current gear of the vehicle, and the light control can be performed in combination with the vehicle startup status and vehicle speed. In some embodiments, when it is determined that the vehicle is stationary and in the P gear parking gear, the lights are turned on to facilitate passengers to unlock / lock the seat belts; when it is determined that the vehicle is not stationary, the lights are turned off. In other embodiments, pressure sensors can be further designed at the vehicle seats, or in-vehicle cameras can be used (after user authorization) to obtain whether there are occupants at each seat. When it is determined that there are no occupants in the car, the luminous seat belt system at the corresponding seat does not emit light. At this time, the luminous intensity can be further controlled according to the status of the passengers getting on and off the vehicle. Taking the driver getting on the vehicle as an example, when there is no one in the driving seat and the driver opens the door, the luminous intensity is calculated according to L=K·ln(L0-L1+1). When the driver is detected to be seated, for example, the pressure value of the pressure sensor at the seat (seat pressure) reaches the set threshold, or the camera in the car determines that there is someone in the driving seat, the luminous intensity of the seat is reduced by a set value, such as 80%, or turned off to reduce unnecessary light. The luminous intensity of the seat belt webbing is reduced by a set value, such as 50%, to avoid the light being too dazzling and affecting the driver's experience. The luminous intensity of the seat belt tongue and the seat belt buckle is maintained to facilitate the driver to quickly find the tongue and buckle positions and improve the experience of fastening the seat belt.

[0050] The fourth luminous signal is generated according to a user button or voice command, thereby meeting personalized control requirements.

[0051] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
