[0014] Thus, the vehicle body includes a second control module and a second optical communication system, the vehicle includes a seat, and the seat includes a first optical communication system. The second optical communication system is configured to receive a first optical signal sent by the first optical communication system. The second control module is configured to determine a target optical communication module based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system. Wireless communication between the seat and the vehicle is then achieved based on the target optical communication module and the first optical communication system. In this way, based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system, a target optical communication module capable of stable communication can be determined in real time. A communication link between the seat and the vehicle body is then established based on the target optical communication module and the first optical communication system, realizing wireless communication between the seat and the vehicle. This improves the stability of wireless communication, the freedom and flexibility of seat use, and meets the seat design requirements of different vehicle models. Compared to using physical wiring harnesses to connect the seat to the vehicle floor, this embodiment achieves wireless communication between the seat and the vehicle body using optical signals, solving the problems of easy cutting, breakage, and fatigue-induced circuit breakage of wired wiring harnesses, reducing the probability of vehicle seat failure, and improving the reliability of the seat system.

[0015] In some embodiments, the second optical communication system includes multiple optical communication modules, and the vehicle further includes multiple second energy transmission modules; The second control module is configured as follows: The second energy transmission module in the target area where the target optical communication module is located is identified as the target energy transmission module; The target energy transmission module is configured to transmit energy to the first energy transmission module of the seat.

[0016] Thus, the second optical communication system includes multiple optical communication modules, and the vehicle also includes multiple second energy transmission modules. The second control module is configured to identify the second energy transmission module in the target area where the target optical communication module is located as the target energy transmission module. The target energy transmission module is configured to transmit energy to the first energy transmission module of the seat. In this way, the seat movement can update and identify the target optical communication module in real time, and simultaneously update and identify the target energy transmission module corresponding to the target area, realizing dynamic collaborative updating of the optical communication module and the energy transmission module, ensuring that signal communication and energy transmission always maintain the optimal matching link during the seat's full-degree-of-freedom movement.

[0017] In some embodiments, each of the optical communication modules includes a second light source, a second light detection unit, and a second light filtering unit; The divergence angle of the second light source is greater than a preset divergence angle; and / or The second center wavelength emitted by the second light source is spaced at a predetermined wavelength distance from the second center wavelength of the first light source of the first optical communication system; and / or The distance between the second light source and the second light detection unit is less than a preset distance; and / or The filtering wavelength of the second optical filtering unit is the same as the center wavelength of the first light source; and / or The second light detection unit receives the field of view angle, and the central axis of the divergence angle of the first light source is perpendicular to the horizontal plane.

[0018] Thus, each optical communication module includes a second light source, a second optical detection unit, and a second optical filtering unit. The divergence angle of the second light source is greater than a preset divergence angle. The second center wavelength emitted by the second light source is spaced from the second center wavelength of the first light source in the first optical communication system by a preset wavelength distance. The distance between the second light source and the second optical detection unit is less than a preset distance. The filtering wavelength of the second optical filtering unit is the same as the center wavelength of the first light source. The receiving field of view of the second optical detection unit and the central axis of the divergence angle of the first light source are both perpendicular to the horizontal plane. In this way, by clearly defining the hardware parameters at the vehicle body and seat ends, the coverage of optical signal transmission, the interference-free transmission, and the high efficiency of reception can be guaranteed. Combined with the second optical communication system and the second control module at the vehicle body end, more stable and efficient wireless optical communication between the seat and the vehicle body can be achieved.

[0019] In some embodiments, the plurality of optical communication modules are arranged along a first axis, wherein the first axis is the length direction of the vehicle; and / or The plurality of optical communication modules are arranged in a rectangular configuration; and / or The multiple optical communication modules are arranged in a cellular network configuration.

[0020] Thus, multiple optical communication modules are arranged along a first axis, which is the length direction of the vehicle; multiple optical communication modules are arranged in a rectangular arrangement; multiple optical communication modules are arranged in a cellular network pattern. In this way, according to the vehicle model positioning and the actual degree of freedom of seat movement, the corresponding optical communication module arrangement can be selected to adapt to the needs of different vehicles, avoid the resource waste or insufficient coverage problems caused by a single arrangement, and thus ensure the continuity of wireless optical communication.

[0021] In some implementations, the second control module is configured to: The second light source of the second optical communication system other than the target optical communication module is turned off; and / or The second energy transmission module, other than the target energy transmission module, is shut down.

[0022] Thus, the second control module is configured to shut down the second light source of the second optical communication system other than the target optical communication module, and to shut down the second energy transmission module other than the target energy transmission module. This avoids crosstalk between multiple light source signals, eliminates visual interference from excess light radiation inside the vehicle to the driver and passengers, improves the accuracy and stability of wireless communication and the user's driving experience to a certain extent, and saves vehicle power.

Detailed Implementation

[0025] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0026] Vehicle seats typically rely on physical wiring harnesses to connect to the vehicle floor, enabling signal interaction and energy transfer between the seat and the vehicle as a whole.

[0027] However, physical wiring harnesses present many unavoidable problems in actual use. For example, during the daily forward and backward movement and angle adjustment of the seat, the wiring harness is constantly subjected to bending, pulling and friction. Long-term use can easily lead to short circuits caused by the outer sheath being cut, or even the wiring harness being pulled out directly. At the same time, repeated mechanical stress can also cause fatigue and breakage of the wires inside the wiring harness, making it a high-frequency failure point of the vehicle seat system.

[0028] In addition, the length and wiring path of physical wiring harnesses are subject to fixed limitations, which greatly restricts the range of movement and adjustment of vehicle seats. It is impossible to achieve flexible adjustment actions such as large-scale translation and 360-degree rotation of the seats. The design and use flexibility of the seats are greatly reduced, and it is difficult to adapt to the current development needs of intelligent and highly flexible car seats.

[0029] Based on the above issues, please refer to Figure 1 This application provides a seat 100 for a vehicle 1000, the seat 100 including a first optical communication system 110, and the body 200 of the vehicle 1000 including a second control module 220 and a second optical communication system 210. The first optical communication system 110 is configured to transmit a first optical signal; The second optical communication system 210 is configured to receive the first optical signal; The second control module 220 is configured as follows: The target optical communication module is determined based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system 210. Wireless communication between the seat 100 and the vehicle is achieved based on the target optical communication module and the first optical communication system 110.

[0030] Specifically, seat 100 is a device installed inside the vehicle to provide support for drivers and passengers, and has functions such as position adjustment, signal interaction, and energy reception.

[0031] The first optical communication system 110 is an optical communication device installed at the end of the seat 100. It is used to generate and send optical signals to the vehicle body 200, and can also be used to receive optical signals sent by the vehicle body 200, so as to realize communication between the seat 100 and the vehicle body 200 through optical signals.

[0032] The vehicle body 200 refers to the main frame structure of the vehicle, which is the mounting carrier for various control systems, communication systems and energy transmission systems of the vehicle, and is used to provide basic support and connection channels for the operation of various components of the vehicle.

[0033] The second control module 220 is the control unit at the vehicle body 200 end. It has functions such as data acquisition, analysis and processing, and command issuance, and can interact with the second optical communication system 210.

[0034] The second optical communication system 210 is an optical communication device installed at the end of the vehicle body 200. It is used to generate and send optical signals to the seat 100, and can also be used to receive optical signals sent by the seat 100, so as to realize communication between the seat 100 and the vehicle body 200 through optical signals.

[0035] The first optical signal is an optical band signal emitted by the first optical communication system 110, used to carry interactive data between the seat 100 and the vehicle body 200.

[0036] The optical communication module is the smallest independent working unit of the second optical communication system 210. The second optical communication system 210 consists of an array of multiple optical communication modules. Each optical communication module is used to receive optical signals, detect signal strength, and transmit relevant data to the second control module 220.

[0037] Signal strength refers to the signal amplitude parameter of the first optical signal, which is used to characterize the transmission quality and transmission distance of the first optical signal. The higher the signal strength, the better the transmission quality of the optical communication link. For example, the root mean square (RMS) value of the first optical signal.

[0038] The target optical communication module is an optical communication module selected by the second control module 220 from multiple optical communication modules of the second optical communication system 210, used to establish a formal communication link with the first optical communication system 110, and is the interactive unit for realizing wireless communication between the vehicle body 200 end and the seat 100 end.

[0039] Wireless communication refers to a two-way data interaction method between the seat 100 and the vehicle body 200, which is achieved without physical wiring and uses optical signals as the transmission carrier. It can complete the transmission of various sensor data, control commands, and audio and video data.

[0040] After the seat is moved and adjusted, based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system 210, the optical communication module with the strongest signal strength can be determined as the target optical communication module. A communication link between the seat 100 and the vehicle body 200 is established based on the target optical communication module and the first optical communication system 110, realizing wireless communication between the seat 100 and the vehicle. This avoids communication interruptions and signal attenuation caused by changes in the position of the seat 100, improving the stability and continuity of wireless communication. As a result, the seat 100 can be adjusted and rotated over a wider range, which to some extent improves the freedom of use of the seat 100. It also improves the flexibility of the structural and layout design of the seat 100, meeting the design requirements of the seat 100 for different vehicle models.

[0041] Compared to using physical wiring harnesses to connect the seat 100 to the floor of the vehicle body 200, the embodiment of this application uses optical signals to achieve wireless communication between the seat 100 and the vehicle body 200, which solves the problems of wired wiring harnesses being easily cut, pulled, or fatigued and broken, reduces the probability of after-sales failure of the seat 100, and improves the reliability and durability of the seat 100 system.

[0042] In one example, a first optical communication system 110 can be fixedly configured at the seat 100 end, such as by mounting a first optical communication system 110 as follows: Figure 2 The optical communication module of the second optical communication system 210 at the vehicle body 200 end is located in the center of the seat cushion of the seat 100, while several optical communication modules of the second optical communication system 210 at the vehicle body 200 end are distributed in different areas of the floor of the vehicle body 200.

[0043] The first optical communication system 110 continuously transmits a first optical signal, while several optical communication modules of the second optical communication system 210 are in a real-time receiving state and can synchronously receive the first optical signal transmitted by the first optical communication system 110. Each optical communication module can independently detect the signal strength of the first optical signal it receives and transmit the signal strength data and the received optical signal data to the second control module 220 in real time.

[0044] The second control module 220 collects, counts, and analyzes the signal strength of each optical communication module in real time. Based on preset judgment rules, such as selecting the module corresponding to the maximum signal strength, it can determine one or more target optical communication modules with the best received first optical signal transmission quality from multiple optical communication modules of the second optical communication system 210, and dynamically update the target optical communication module to establish a communication link with the first optical communication system 110 through the target optical communication module. Then, based on the communication link, it realizes data interaction between the seat 100 and the vehicle body 200, ensuring the stability of wireless communication.

[0045] In one example, each optical communication module of the second optical communication system 210 includes a photodetector that can detect the RMS value of the first optical signal. The second control module 220 can select the optical communication module with the largest RMS or several optical communication modules whose RMS exceeds a set threshold as the target optical communication modules on the floor side.

[0046] It should be noted that the RMS value of the first optical signal detected by the optical communication module of the second optical communication system 210 in this embodiment of the application is only for illustrative purposes. In other embodiments, other values ​​can be used to characterize the signal strength of the first optical signal. This is not limited here and can be set according to the actual situation.

[0047] In one example, each optical communication module of the second optical communication system 210 also includes a light source unit and an optical filter, such as a light-emitting diode (LED) light source. All optical communication modules share a set of modulation circuits, light emission driving circuits, and receiving demodulation circuits. Meanwhile, the optical communication modules of the first optical communication system 110 also include light source units and optical filters. The modulation circuits, light emission driving circuits, and receiving demodulation circuits used in the second optical communication system 210 are the same as those in the first optical communication system 110, to ensure that the modulation and demodulation processes of the optical signal at both ends can be matched, reduce transmission distortion, and improve the reliability of communication between the first optical communication system 110 and the second optical communication system 210.

[0048] Based on the target optical communication module and the first optical communication system 110, a wireless communication link is established between the seat 100 and the vehicle, such as... Figure 3 As shown, the transmitting side can modulate the original data information to be transmitted through a modulation circuit, such as mapping a binary bit signal onto a signal waveform of a certain amplitude. The modulated signal is then input into the light emission driving circuit to generate a driving signal with a certain driving capability. This driving signal can drive the LED light source to output light wave signals of different intensities. The light wave signal reaches the receiving end through a wireless optical channel. The receiving end can filter stray background light outside a certain range of the center wavelength or backscattered light emitted from the light source of the same transceiver unit through an optical filter. The filtered received signal light is then converted into an electrical signal through a photodetector via photoelectric conversion effect. Simultaneously, it undergoes demodulation circuit decision decoding and other operations to recover the original data information. The vehicle body 200 side can also merge multiple signals to recover the original data information. For example, video and audio information can be transmitted from the vehicle body 200 side to the seat 100 side, and temperature and pressure sensing information from the seat 100 side can be transmitted to the vehicle body 200 side.

[0049] Understandably, from the communication bandwidth requirements shown in Table 1 and the achievable theoretical bandwidths of various wireless communication technologies, it can be seen that optical communication technology has the advantage of large bandwidth, which can meet the bandwidth requirements of the seat 100 for video transmission. Therefore, the optical band used in the embodiments of this application can be an uncertified spectrum band, thereby avoiding interference from the wireless communication system.

[0050] Table 1

[0051] In summary, based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system 210, a target optical communication module capable of stable communication can be determined in real time. A communication link between the seat 100 and the vehicle body 200 is then established based on the target optical communication module and the first optical communication system 110, enabling wireless communication between the seat 100 and the vehicle. This improves the stability of wireless communication, the freedom and flexibility of using the seat 100, and meets the design requirements of the seat 100 for different vehicle models. Compared to using physical wiring harnesses to connect the seat 100 to the floor of the vehicle body 200, this embodiment uses optical signals to achieve wireless communication between the seat 100 and the vehicle body 200, solving the problems of easily cut, broken, and fatigue-induced circuit breaks in wired wiring harnesses, reducing the probability of seat 100 failure, and improving the reliability of the seat 100 system.

[0052] In some embodiments, the first optical communication system 110 is located at the geometric center of the seat cushion of the seat 100.

[0053] Specifically, the seat cushion of seat 100 is the structural part of seat 100 used to support the buttocks of the driver and passenger, that is, the main load-bearing area of ​​seat 100.

[0054] The geometric center position refers to the center point obtained by geometric calculation based on the outer contour of the seat cushion of the seat 100. It is the most central area in the space of the seat cushion and can be used as a reference point to judge the change in spatial position of the seat 100 during movement and rotation.

[0055] By placing the first optical communication system 110 at the geometric center of the seat cushion of the seat 100, physical interference with other components of the vehicle body 200 can be avoided. Simultaneously, when the seat 100 is in operation, the first optical communication system 110, located at the geometric center of the seat cushion, continuously emits a first optical signal at a preset cycle. Because the emission point is at the center of the seat 100, the first optical signal can radiate towards the floor side of the vehicle body 200 at a uniform divergence angle, thereby ensuring that multiple optical communication modules of the second optical communication system 210 can receive the optical signal. This lays the foundation for subsequently determining the target optical communication module based on the signal strength of the first optical signal and establishing the optimal communication link.

[0056] Thus, the first optical communication system 110 is located at the geometric center of the seat cushion of the seat 100. This ensures that multiple optical communication modules of the second optical communication system 210 can receive optical signals, laying the foundation for subsequently determining the target optical communication module and establishing the optimal communication link based on the signal strength of the first optical signal.

[0057] Please refer to it again. Figure 1 In some embodiments, the seat 100 further includes a first energy transmission module 130; The first energy transmission module 130 is configured to receive energy transmitted from the second energy transmission module 230 of the vehicle body 200.

[0058] Specifically, the first energy transmission module 130 is an energy receiving device, such as a receiving coil, installed at the end of the seat 100. It is used to convert the wireless energy transmitted at the end of the vehicle body 200 into electrical energy that can be used by various electronic and electrical devices of the seat 100 to power the seat 100 system.

[0059] The second energy transmission module 230 is an energy transmitting device, such as a transmitting coil, installed at the end of the vehicle body 200. It is used to convert the vehicle's electrical energy into wireless energy signals and transmit them outward, providing an energy source for the first energy transmission module 130 at the end of the seat 100.

[0060] Energy transmission refers to the process of transferring electrical energy from the second energy transmission module 230 at the vehicle body 200 end to the first energy transmission module 130 at the seat 100 end through non-physical contact methods such as wireless magnetic coupling and electromagnetic induction, which can provide power supply for various electronic devices in the seat 100.

[0061] The first energy transmission module 130 receives energy from the second energy transmission module 230 of the vehicle body 200, which can provide a continuous and stable power supply to the display device, speaker, sensor and charging device of the seat 100 and other components 140, ensuring the normal operation of the seat components 140.

[0062] In one example, seat 100 may include one or more of a display device, a speaker, a sensor, and a charging device, such as a seat back display, a seat headrest speaker, a seat heating temperature sensor, a seat pressure sensor, and a wireless charging device. It receives energy transmitted from the second energy transmission module 230 of the vehicle body 200 through the first energy transmission module 130, which can provide a continuous and stable power supply for the display device, speaker, sensor, and charging device, ensuring the normal operation of various devices.

[0063] Thus, the seat 100 also includes a first energy transmission module 130. This provides a continuous and stable power supply to the seat components 140, ensuring the normal operation of the seat components 140 and improving the stability of wireless energy transmission, as well as the freedom and flexibility of using the seat 100.

[0064] In some embodiments, the seat 100 further includes a first control module 120; The first control module 120 is configured to transmit data collected by the seat components 140 to the second optical communication system 210 of the vehicle body 200 via the first optical communication system 110.

[0065] Specifically, the first control module 120 is a control unit integrated on the seat 100. It is used to collect, summarize, process and transmit data of various seat components 140. It can also be used to receive control commands from the vehicle body 200 and drive the seat 100 components to perform corresponding operations.

[0066] Seat components 140 refer to various functional and sensing components integrated on the seat 100, including but not limited to the seat 100 heating temperature sensor, seat 100 pressure sensor, position sensor, seat 100 back display screen, headrest speaker, seat 100 adjustment drive components, etc.

[0067] The collected data includes various information and data detected and generated by the various components 140 of the seat 100 during operation, such as sensor data such as temperature, pressure, and real-time position of the seat 100, status data such as the working status of the display screen, the playback status of the speaker, and the working status of the heating module, as well as fault data such as abnormal operating parameters and fault codes of the components 140.

[0068] The first control module 120 can wirelessly transmit data from the seat 100 side by sending the data collected by the seat components 140 to the second optical communication system 210 of the vehicle body 200 via the first optical communication system 110.

[0069] Thus, the seat 100 also includes a first control module 120; the first control module 120 is configured to transmit data collected by the seat components 140 to a second optical communication system 210 of the vehicle body 200 via a first optical communication system 110. In this way, wireless data transmission on the seat 100 side can be realized by transmitting data collected by the seat components 140 to the second optical communication system 210 of the vehicle body 200 via the first optical communication system 110.

[0070] In some embodiments, the first optical communication system 110 includes a first light source, a first light detection unit, and a first light filtering unit; The divergence angle of the first light source is greater than the preset divergence angle; and / or The first center wavelength emitted by the first light source is spaced apart from the second center wavelength of the second light source of the second optical communication system 210 by a preset wavelength distance; and / or The distance between the first light source and the first light detection unit is less than a preset distance; and / or The central axis of the field of view received by the first light detection unit and the divergence angle of the second light source are both perpendicular to the horizontal plane.

[0071] Specifically, the first light source is a component in the first optical communication system 110 that converts electrical signals into optical signals, such as an LED light source, which is also the source that emits the first optical signal at the end of the seat 100. It is used to convert the modulated electrical drive signal into an optical band signal carrying data information and emit it outward.

[0072] The first optical detection unit is a component in the first optical communication system 110 that converts optical signals into electrical signals. It is used to receive optical signals emitted by the second optical communication system 210 at the vehicle body 200 end and convert them into electrical signals through photoelectric conversion effect, providing a data basis for subsequent signal demodulation.

[0073] The first optical filtering unit is an optical signal filtering device in the first optical communication system 110. It is used to filter out optical signals within a preset wavelength range, filter out stray background light, optical signals of non-target wavelengths and backscattered light, and improve the reception purity of optical signals to a certain extent.

[0074] The divergence angle is the range of angles at which the light rays deviate from the emission center axis when the first light source emits a light signal. It can be used to determine the radiation coverage of the light signal; the larger the angle, the wider the coverage area of ​​the light signal.

[0075] The preset divergence angle is a threshold value for the light source divergence angle that is pre-set based on actual application scenarios such as the moving range of the seat 100 and the layout of the floor optical communication module of the vehicle body 200. It is used to determine whether the light source coverage capability meets the usage requirements.

[0076] The first center wavelength is the wavelength value of the optical signal emitted by the first light source, and it is also the spectral characteristic of the optical signal. It can determine the transmission characteristics and filtering matching standards of the optical signal.

[0077] The second center wavelength is the wavelength value of the optical signal emitted by the second light source in the second optical communication system 210 at the vehicle body 200 end, and it is also the spectral characteristic of the optical signal at the vehicle body 200 end.

[0078] The preset wavelength distance is a pre-defined threshold difference between the center wavelengths of the two light sources. It is used to ensure that the spectral characteristics of the optical signals at both ends can be accurately distinguished and to avoid crosstalk.

[0079] The preset distance is a pre-defined installation distance threshold between the first light source and the first light detection unit, used to ensure the structural compactness of the optical communication system and the coordination of optical signal transmission and reception.

[0080] The receiving field of view is the angular range within which the first optical detection unit can receive optical signals. Optical signals within this angular range can be identified and converted by the detection unit; those outside this range cannot be effectively received.

[0081] The central axis refers to the main emission axis when the second light source emits light signals; it is the baseline for light signal radiation.

[0082] The horizontal plane refers to the plane parallel to the floor of the vehicle body 200, which is the reference plane for the installation of the optical communication system of the seat 100 and the transmission of optical signals.

[0083] By setting the divergence angle of the first light source to be greater than a preset divergence angle, it can be ensured that the optical signal can cover the entire range of movement of the seat 100; by setting the first center wavelength of the first light source and the second center wavelength of the second light source of the vehicle body 200 to a preset wavelength distance, a spectrum basis for realizing wavelength division duplex communication can be provided; by controlling the installation distance between the first light source and the first optical detection unit within a preset distance, it can be ensured that the structure of the first light source and the first optical detection unit is compact and nearly coincident with the light transmission and reception link; by adjusting the receiving field of view of the first optical detection unit to be perpendicular to the horizontal plane and the central axis of the divergence angle of the second light source to be perpendicular to the horizontal plane, the effective receiving angle of the detection unit can be precisely matched with the emission direction of the optical signal at the end of the vehicle body 200.

[0084] When the seat 100 emits an optical signal, the modulated electric drive signal drives the first light source, which can emit the first optical signal in a range greater than the preset divergence angle. The first optical signal has a first center wavelength as its spectral characteristic and can cover multiple optical communication modules on the floor side of the vehicle body 200, ensuring that the vehicle body 200 can receive an effective optical signal no matter where the seat 100 moves. Since the first center wavelength and the second center wavelength are separated by a preset wavelength distance, the optical signal emitted by the seat 100 will not overlap with the optical signal emitted by the vehicle body 200 in the spectrum, thus avoiding crosstalk between the two-way optical signals.

[0085] When the optical signal emitted by the second optical communication system 210 at the vehicle body 200 is transmitted to the seat 100, it is filtered by the first optical filtering unit. Stray background light, optical signals of non-second center wavelengths, and backscattered light are effectively filtered out, and only the effective optical signal that conforms to the wavelength standard is retained. Since the receiving field of view of the first optical detection unit is perpendicular to the horizontal plane with the central axis of the second light source, the effective optical signal can enter the receiving range of the detection unit at the optimal angle, maximizing the receiving efficiency of the optical signal and reducing transmission loss. The first optical detection unit converts the filtered effective optical signal into an electrical signal, and after processing by the demodulation circuit, the original data is recovered, completing the signal transmission from the vehicle body 200 to the seat 100.

[0086] Thus, the first optical communication system 110 includes a first light source, a first optical detection unit, and a first optical filtering unit; the divergence angle of the first light source is greater than a preset divergence angle; the first center wavelength emitted by the first light source is spaced apart from the second center wavelength of the second light source of the second optical communication system 210 by a preset wavelength distance; the distance between the first light source and the first optical detection unit is less than a preset distance; the receiving field of view of the first optical detection unit and the central axis of the divergence angle of the second light source are both perpendicular to the horizontal plane. In this way, by clearly defining the hardware parameters of the vehicle body 200 and the seat 100, the coverage of optical signal transmission, the interference-free transmission, and the high efficiency of reception can be guaranteed. Combined with the second optical communication system 210 and the second control module 220 at the vehicle body 200 end, a more stable and efficient wireless optical communication between the seat 100 and the vehicle body 200 can be achieved.

[0087] This application provides a vehicle 1000, the vehicle body 200 of which includes a second control module 220 and a second optical communication system 210, the vehicle 1000 includes a seat 100, and the seat 100 includes a first optical communication system 110. The second optical communication system 210 is configured to receive a first optical signal sent by the first optical communication system 110; The second control module 220 is configured as follows: The target optical communication module is determined based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system 210. Wireless communication between the seat 100 and the vehicle is achieved based on the target optical communication module and the first optical communication system 110.

[0088] Specifically, the vehicle 1000 includes the aforementioned seat 100 and body 200. The body 200 includes a second control module 220 and a second optical communication system 210, and the seat 100 includes a first optical communication system 110.

[0089] The vehicle body 200 of the vehicle 1000 in this embodiment is the same as the seat 100 described above, and can be referred to the description of the seat 100 described above, which will not be repeated here.

[0090] Thus, the vehicle body 200 of vehicle 1000 includes a second control module 220 and a second optical communication system 210. The vehicle includes a seat 100, and the seat 100 includes a first optical communication system 110. The second optical communication system 210 is configured to receive a first optical signal sent by the first optical communication system 110. The second control module 220 is configured to determine a target optical communication module based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system 210. Based on the target optical communication module and the first optical communication system 110, wireless communication between the seat 100 and the vehicle is performed. In this way, based on the signal strength of the first optical signal received by each optical communication module in the second optical communication system 210, a target optical communication module capable of stable communication can be determined in real time. A communication link between the seat 100 and the vehicle body 200 is established based on the target optical communication module and the first optical communication system 110, realizing wireless communication between the seat 100 and the vehicle. This improves the stability of wireless communication, the freedom and flexibility of use of the seat 100, and meets the design requirements of the seat 100 for different vehicle models. Compared to using physical wiring harnesses to connect the seat 100 to the floor of the vehicle body 200, the embodiment of this application uses optical signals to achieve wireless communication between the seat 100 and the vehicle body 200, which solves the problems of wired wiring harnesses being easily cut, pulled, or fatigued and broken, reduces the failure probability of the seat 100, and improves the reliability of the seat 100 system.

[0091] In some embodiments, the second optical communication system 210 includes multiple optical communication modules, and the vehicle also includes multiple second energy transmission modules 230; The second control module 220 is configured as follows: The second energy transmission module 230 in the target area where the target optical communication module is located is identified as the target energy transmission module; The target energy transmission module is configured to transmit energy to the first energy transmission module 130 of the seat 100.

[0092] Specifically, the optical communication module is the smallest independent working unit of the second optical communication system 210. The second optical communication system 210 is an array composed of multiple optical communication modules. Each optical communication module is used to receive optical signals, detect signal strength, and transmit relevant data to the second control module 220. The multiple optical communication modules are distributed in different areas of the floor of the vehicle body 200.

[0093] The second energy transmission module 230 is an energy transmission functional unit, such as a transmitting coil, installed at the end of the vehicle body 200. It is used to convert the vehicle's electrical energy into wireless energy signals and transmit them outward. Multiple second energy transmission modules 230 are distributed in different areas of the floor of the vehicle body 200.

[0094] The target area is a pre-defined area on the floor of the vehicle body 200. Each optical communication module corresponds to a unique target area on the floor of the vehicle body 200, and a matching second energy transmission module 230 is configured in this area.

[0095] The target energy transmission module is the energy transmission module selected by the second control module 220 from multiple second energy transmission modules 230, which belongs to the same target area as the target optical communication module. It is the transmitting unit at the vehicle body 200 end that provides wireless energy to the seat 100.

[0096] The second optical communication system 210 at the vehicle body 200 end includes multiple distributed optical communication modules. Each optical communication module is arranged according to a preset rule in the moving coverage area of ​​the seat 100 on the floor of the vehicle body 200. At the same time, there is a second energy transmission module 230 that matches the optical communication module. Each second energy transmission module 230 and the corresponding optical communication module are arranged in the same physical area of ​​the floor of the vehicle body 200 to form a regional matching unit to cover the entire moving range of the seat 100. All optical communication modules and second energy transmission modules 230 establish electrical and signal connections with the second control module 220 and are subject to unified scheduling by the second control module 220.

[0097] During the movement of seat 100, the distribution of the received intensity of the first optical signal emitted by the first optical communication system 110 at the vehicle body 200 changes. The second control module 220 collects the signal intensity data of each optical communication module in real time, re-screens and determines the new target optical communication module, and simultaneously locks the new target area. The second energy transmission module 230 in the target area is updated to the new target energy transmission module, and the original target energy transmission module is turned off. This realizes the dynamic collaborative update of the optical communication module and the energy transmission module, ensuring that the signal communication and energy transmission always maintain the optimal matching link during the full-degree-of-freedom movement of seat 100.

[0098] In one example Figure 2 The vehicle body 200 shown may include 18 optical communication modules and 2 second energy transmission modules 230. The 18 optical communication modules are distributed in a 3×6 rectangular structure. The 3×3 optical communication modules on the front side of the seat 100 correspond to the front second energy transmission modules 230, and the 3×3 optical communication modules on the rear side of the seat 100 correspond to the rear second energy transmission modules 230. If one of the 18 optical communication modules is determined to be the target optical communication module, if the target optical communication module is one of the 3×3 optical communication modules on the front side of the seat 100, then the front second energy transmission module 230 is determined to be the target energy transmission module; if the target optical communication module is one of the 3×3 optical communication modules on the rear side of the seat 100, then the rear second energy transmission module 230 is determined to be the target energy transmission module.

[0099] Thus, the second optical communication system 210 includes multiple optical communication modules, and the vehicle also includes multiple second energy transmission modules 230. The second control module 220 is configured to identify the second energy transmission module 230 in the target area where the target optical communication module is located as the target energy transmission module. The target energy transmission module is configured to transmit energy to the first energy transmission module 130 of the seat 100. In this way, the movement of the seat 100 can update and identify the target optical communication module in real time, and simultaneously update and identify the target energy transmission module corresponding to the target area, realizing dynamic collaborative updating of the optical communication module and the energy transmission module, ensuring that the signal communication and energy transmission always maintain the optimal matching link during the full-degree-of-freedom movement of the seat 100.

[0100] In some implementations, each optical communication module includes a second light source, a second light detection unit, and a second light filtering unit; The divergence angle of the second light source is greater than the preset divergence angle; and / or The second center wavelength emitted by the second light source is spaced apart from the first center wavelength of the first light source of the first optical communication system 110 by a preset wavelength distance; and / or The distance between the second light source and the second light detection unit is less than a preset distance; and / or The filtering wavelength of the second optical filter unit is the same as the center wavelength of the first light source; and / or The central axis of the receiving field of view of the second light detection unit and the divergence angle of the first light source are both perpendicular to the horizontal plane.

[0101] Specifically, the second light source is the core device in the single optical communication module at the vehicle body 200 end that realizes the conversion of electrical signals to optical signals. It is the source of light transmission from the vehicle body 200 end to the seat 100, and can convert the modulated electric drive signal into an optical band signal carrying data information and transmit it outward.

[0102] The second optical detection unit is the core device in the single optical communication module at the vehicle body 200 end, which realizes the conversion of optical signals to electrical signals. It can receive the optical signals emitted by the first optical communication system 110 at the seat 100 end and convert them into electrical signals through photoelectric conversion effect, providing a basis for subsequent signal demodulation.

[0103] The second optical filtering unit is an optical signal filtering device in the single optical communication module at the 200 end of the vehicle body. It can accurately filter out optical signals within a preset wavelength range, filter out stray background light, non-target wavelength optical signals and backscattered light in the vehicle, and improve the reception purity of effective optical signals.

[0104] The filter wavelength is the core wavelength value of the optical signal that the second optical filter unit can allow to pass through. It is the core criterion for the filter unit to select effective optical signals and matches the center wavelength of the target optical signal.

[0105] Setting the divergence angle of the second light source to be greater than a preset divergence angle ensures that the optical signal of a single module can cover the movement range of the seat 100 within the corresponding area. Setting the second center wavelength emitted by the second light source to be spaced apart from the center wavelength of the first light source at the seat 100 by a preset wavelength distance provides a spectrum basis for bidirectional wavelength division duplex communication between the seat 100 and the vehicle body 200. Controlling the installation distance between the second light source and the second optical detection unit within a preset distance ensures a compact module structure and near-coincidence of the light and signal transmission links, reducing signal transmission loss. Precisely matching the filtering wavelength of the second optical filtering unit to the center wavelength of the first light source ensures that only the effective optical signal from the seat 100 can pass through. Adjusting the receiving field of view of the second optical detection unit to be perpendicular to the horizontal plane along with the central axis of the divergence angle of the first light source allows for precise matching of the effective receiving angle of the detection unit with the emission direction of the optical signal from the seat 100.

[0106] Thus, each optical communication module includes a second light source, a second optical detection unit, and a second optical filtering unit; the divergence angle of the second light source is greater than a preset divergence angle; the second center wavelength emitted by the second light source is spaced from the first center wavelength of the first light source of the first optical communication system 110 by a preset wavelength distance; the distance between the second light source and the second optical detection unit is less than a preset distance; the filtering wavelength of the second optical filtering unit is the same as the center wavelength of the first light source; the receiving field of view of the second optical detection unit and the central axis of the divergence angle of the first light source are both perpendicular to the horizontal plane. In this way, by clearly defining the hardware parameters of the vehicle body 200 and the seat 100, the coverage of optical signal transmission, the interference-free transmission, and the high efficiency of reception can be guaranteed. Combined with the second optical communication system 210 and the second control module 220 at the vehicle body 200, a more stable and efficient wireless optical communication between the seat 100 and the vehicle body 200 can be achieved.

[0107] In some embodiments, multiple optical communication modules are arranged along a first axis, wherein the first axis is the length direction of the vehicle; and / or Multiple optical communication modules are arranged in a rectangular pattern; and / or Multiple optical communication modules are arranged in a cellular network configuration.

[0108] Specifically, the first axial arrangement refers to a layout in which multiple optical communication modules are arranged linearly along a single axis, such as... Figure 4 The diagram shows four optical communication modules arranged in each of the two rows along the length of the vehicle to accommodate the basic mobility requirements of the 100 seats.

[0109] The length direction of the vehicle is the direction in which the vehicle extends from the front to the rear. It is the main longitudinal axis of the vehicle and also the most common direction of movement for seat 100.

[0110] Rectangular arrangement refers to a layout in which multiple optical communication modules are arranged in a rectangular array, such as... Figure 5 The arrangement forms a 4×5 array, creating a planar grid coverage to accommodate the forward and backward, left and right bidirectional movement of the seat 100.

[0111] Cellular network layout refers to an array layout in which multiple optical communication modules are spliced ​​together using regular hexagonal basic units to form a honeycomb pattern, such as... Figure 6 The front and rear rows are arranged in an equidistant, staggered pattern to accommodate the seats' 100 degrees of freedom of movement or rotation.

[0112] Based on the vehicle model positioning and the actual degree of freedom of movement of the seat 100, the corresponding optical communication module arrangement can be selected to adapt to the needs of different vehicles, avoid resource waste or insufficient coverage caused by a single arrangement, and thus ensure the continuity of wireless optical communication.

[0113] In one example, for a vehicle where the seat 100 only has the ability to move forward and backward along the length of the vehicle, multiple optical communication modules can be arranged along the first axis, linearly along the longitudinal axis from the front to the rear of the vehicle, ensuring seamless connection of the optical signal coverage areas of adjacent modules; for a vehicle where the seat 100 has the ability to move forward and backward and left and right in both directions, a rectangular arrangement is adopted, arranging multiple optical communication modules in a rectangular array with equal spacing in the horizontal and vertical directions, forming a planar grid coverage of the vehicle body 200 floor horizontally along the width direction of the vehicle and vertically along the length direction of the vehicle; for a vehicle where the seat 100 has the ability to move forward, backward, left and right and rotate with full degrees of freedom, a cellular network arrangement can be adopted, arranging optical communication modules with regular hexagons as the basic unit, with the coverage areas of each module connected to each other and without overlapping blind spots, achieving full-area high-precision coverage of the vehicle body 200 floor.

[0114] Thus, multiple optical communication modules are arranged along a first axis, which is the length direction of the vehicle; multiple optical communication modules are arranged in a rectangular arrangement; multiple optical communication modules are arranged in a cellular network pattern. In this way, according to the vehicle model positioning and the actual degree of freedom of movement of the seat 100, the corresponding optical communication module arrangement can be selected to adapt to the needs of different vehicles, avoid resource waste or insufficient coverage caused by a single arrangement, and thus ensure the continuity of wireless optical communication.

[0115] In some implementations, the second control module 220 is configured to: The second light source of the second optical communication system 210, other than the target optical communication module, is turned off; and / or The second energy transmission module 230, other than the target energy transmission module, is shut down.

[0116] Specifically, after identifying the target optical communication module and the target energy transmission module, the second control module 220 can control the second light source of the second optical communication system 210 other than the target optical communication module to turn off. By stopping the optical signal transmission function of all non-target optical communication modules, crosstalk between optical signals from multiple light sources can be avoided. Only the second light source of the target optical communication module is kept on, enabling the target optical communication module to perform bidirectional optical signal interaction with the first optical communication system 110 at the seat 100 end. This improves the accuracy and stability of wireless communication to a certain extent. It can also reduce the visual interference of excess light radiation in the vehicle to the driver and passengers, and improve the driving experience.

[0117] It can also control all second energy transmission modules 230 other than the target energy transmission module to shut down. By stopping the energy transmission function of all other non-target second energy transmission modules 230, and keeping only the target module working, the vehicle's electrical energy will no longer be consumed, thus solving the problem of energy waste caused by the continuous operation of multiple modules and improving the utilization efficiency of vehicle electrical energy to a certain extent.

[0118] Thus, the second control module 220 is configured to shut down the second light source of the second optical communication system 210 other than the target optical communication module; and to shut down the second energy transmission module 230 other than the target energy transmission module. This avoids crosstalk between multiple light source signals, eliminates visual interference from excess light radiation inside the vehicle to the driver and passengers, improves the accuracy and stability of wireless communication and the user's driving experience to a certain extent, and saves vehicle energy.

[0119] The following is Figure 7 The data communication process between the seat 100 and the vehicle body 200 in the embodiments of this application will be explained using examples: First, the side light transceiver system of seat 100, namely the first optical communication system 110, periodically sends light signals with fixed data information, namely the first light signals, to the floor-side port of vehicle body 200. The second control module 220 on the floor side is responsible for calculating the RMS value of the photoelectric detector received signals of all units.

[0120] Then, the second control module 220 selects the receiving unit with the largest RMS or several receiving units with RMS exceeding a set threshold as the effective optical transceiver units on the floor side. The LED light sources of the remaining units are turned off, and the electrical signal output by the photodetector does not participate in signal demodulation. The coil of the phototransceiver unit with the largest RMS value is the optimal transmitting coil. At this time, the optimal coil is turned on, and the other coils are turned off.

[0121] Finally, under the premise of optimal optical communication quality, data interaction is carried out between the seat 100 and the floor, transmitting video and audio information from the floor to the seat 100, transmitting temperature and pressure sensing information of the seat 100 to the floor, and wirelessly powering various sensors, speakers, displays and other vehicle components 140 on the seat 100.
