Description

[Technical Field]

[0001] The present invention relates to wheels, and more particularly to a wheel system and method for indicating the state of a driver of a vehicle. [Background technology]

[0002] With advances in technology, vehicles are increasingly being equipped with functions for improving driving safety, such as inter-vehicle distance measurement systems and oncoming vehicle approach display systems. For example, Patent Document 1 discloses an intelligent tire system as an in-vehicle system for improving such safety. However, many of the conventional designs for these systems use a detection device mounted on the vehicle to detect other vehicles and the surrounding environment and issue a warning to the driver of the vehicle. Therefore, for example, if an abnormality occurs in the vehicle itself, the drivers of surrounding vehicles (e.g., other vehicles behind the abnormal vehicle) are unable to immediately know of the abnormality and may not have enough time to react, which could lead to a traffic accident.

[0003] [Patent Document 1] Patent No. 4627108 Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a wheel system and method that can alleviate at least one of the drawbacks of the prior art. [Means for solving the problem]

[0005] According to one aspect of the present invention, a wheel system is configured for use with a vehicle body and includes a control device and a wheel assembly. The control device includes a wireless communication module, a sensing module configured to perform detection related to a target object within the vehicle body and generate sensing data, and a warning control module. The warning control module stores multiple warning conditions and multiple warning parameters corresponding to the warning conditions, and is configured to obtain a warning parameter corresponding to the warning condition and output a control signal including the corresponding warning parameter via the wireless communication module when it determines that one of the warning conditions is met based on the sensing data. The wheel assembly is configured to be attached to the vehicle body and includes a wheel, a lighting module disposed on the wheel and configured to be controlled to emit light in one of multiple color patterns, a lighting control module disposed on the wheel and electrically connected to the lighting module, and a power generation mechanism disposed on the wheel and configured to be driven by the wheel to generate power. The lighting control module includes a wireless communication unit configured to receive a control signal from the wireless communication module of the control device and a lighting control unit configured to control the lighting module to emit light in a color pattern corresponding to the corresponding warning parameter included in the control signal. Power is provided to the lighting module and the lighting control module.

[0006] According to another aspect of the present invention, a method is performed by the wheel system described above to indicate a driver status of a vehicle body, where the target object is the driver. The method includes: a sensing module performing detection related to the target object to generate sensing data; a warning control module outputting a control signal including a warning parameter corresponding to the warning condition when determining that any one warning condition is met based on the sensing data; a lighting control module receiving the control signal from the warning control module via a wireless communication unit and identifying the corresponding warning parameter included in the control signal; and a lighting control module controlling the lighting module to emit light in a color pattern corresponding to the corresponding warning parameter included in the control signal. [Effects of the Invention]

[0007] The wheel system performs detection related to a target object (e.g., a driver) in the interior space while the vehicle is moving, generates sensing data, and if it determines based on the sensing data that one of the warning conditions is met, controls the wheel assembly to emit light in one of the color patterns. Therefore, the emitted light can warn surrounding people and vehicles and prevent them from approaching the vehicle, thereby reducing the possibility of a traffic accident. Specifically, surrounding people can be, for example, pedestrians or drivers of other vehicles, motorcycles, or bicycles.

[0010] Before describing the present invention in more detail, it should be noted that, where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or similar elements that may have similar characteristics.

[0011] 1 to 4, a wheel system 200 according to one embodiment of the present invention is configured for use in a vehicle body 800. The wheel system 200 includes a wheel assembly 3 configured to be attached to the vehicle body 800, and a control device 4 configured to be disposed in an interior space 801 of the vehicle body 800 and electrically connected to the wheel assembly 3. Specifically, a tire can be attached to the wheel assembly 3.

[0012] The control device 4 includes a wireless communication module 41, a sensing module 42, and a warning control module 43 electrically connected to the wireless communication module 41 and the sensing module 42. The wireless communication module 41 is configured to wirelessly communicate with the wheel assembly 3 using a wireless communication technology (e.g., Bluetooth®).

[0013] The sensing module 42 is configured to perform detection related to a target object in the interior space 801 of the vehicle body 800, generate a sensing data set, and transmit the sensing data set to the warning control module 43. The sensing module 42 includes a millimeter-wave sensor 421, an imaging device 422, and an alcohol sensor 423. The sensing data set includes first sensing data generated by the millimeter-wave sensor 421, second sensing data generated by the imaging device 422, and third sensing data generated by the alcohol sensor 423. The target object is, for example, a human body, and more specifically, a driver of the vehicle.

[0014] The millimeter wave sensor 421 is configured to detect a target object (e.g., a driver) using millimeter wave radar technology and generate first sensing data. Specifically, the millimeter wave sensor 421 is configured to emit a millimeter wave signal having a wavelength of 1 mm to 10 mm and a frequency of 58 GHz to 62 GHz to a driver sitting in the driver's seat of a vehicle (i.e., a target object), detect the millimeter wave signal reflected by the driver, and generate the first sensing data.

[0015] The imaging device 422 may be a camera and is configured to capture an image or video of the driver (for example, by capturing an image of the driver's seat or a specific area) to generate second sensing data. The alcohol sensor 423 is configured to detect the alcohol content in the air inside the vehicle body 800 (specifically, around the driver and around the driver's seat) to generate third sensing data. That is, the alcohol sensor 423 is used to measure the alcohol content in the air exhaled by the driver.

[0016] The warning control module 43 includes a signal analysis unit 431, an image analysis unit 432, a behavior analysis unit 433, a concentration analysis unit 434, and a warning control unit 435. The warning control module 43 stores a plurality of warning conditions and a plurality of warning parameters respectively corresponding to the warning conditions.

[0017] The signal analysis unit 431 is configured to obtain the heart rate and respiration rate of the driver based on the first sensing data generated by the millimeter wave sensor 421. Methods for obtaining the heart rate and respiration rate based on millimeter wave signals are well known to those skilled in the art, and will not be described in further detail for the sake of brevity.

[0018] The image analysis unit 432 is configured to obtain a human body image portion (ie, an image portion including the driver) from the second sensing data generated by the imaging device 422 using image analysis techniques.

[0019] The behavior analysis unit 433 includes a behavior determination model and is configured to determine the behavior of the human body image portion (i.e., driver behavior) based on the human body image portion using the behavior determination model. The behavior determination model relates to, but is not limited to, data collection and preprocessing, feature extraction, behavior analysis and classification, behavior identification, time series analysis, risk determination, warning, intervention, etc.

[0020] Specifically, data collection and preprocessing include collecting data using a sensor (not shown; for example, the sensing module 42 may be used as this sensor, or a separate sensor may be provided and connected to the behavior analysis unit 433). For example, sensors such as an on-board camera, an infrared camera, and a pressure sensor may be used to collect the driver's facial features, head movements, and gaze direction. Feature extraction includes extracting features such as facial features such as blink frequency, blink count, eye movement trajectory, and mouth opening, as well as head rotation angle, head rotation duration, head rotation frequency, and whether the driver's gaze is focused on the road or off the road for a long period of time. Behavior analysis and classification include analyzing the extracted features using a machine learning model, which may be a pre-trained convolutional neural network (CNN) or long short-term memory (LSTM). Behavior identification includes identifying whether the driver is fatigued, distracted, or focused based on the analysis results of the extracted features. The time series analysis includes analyzing changes in the extracted features over time to determine whether the driver is engaging in risky driving behavior. The risk determination includes setting different thresholds for the extracted features, and when any of the extracted features exceeds the respective thresholds, the behavior analysis unit 433 can determine that the driver is engaging in risky driving behavior. The warning includes obtaining a determination result on whether the driver's behavior matches any one of multiple preset risky behaviors to determine whether a warning should be output, and outputting different levels of warning (e.g., sound, vibration, visual presentation) based on the determination result. In some embodiments, the wheel system 200 may be electrically connected to a central control system (not shown) of the vehicle, and the intervention includes the wheel system 200 and the central control system working together to interfere with the vehicle's movement (e.g., slowing down or braking).

[0021] The image analysis techniques may include, but are not limited to, converting the image to grayscale, performing a binarization process, detecting the contours of various objects in the image, and identifying human body image portions. The behavior determination model may be trained by using an algorithm to analyze and recognize various risky driver behaviors while driving a vehicle. Risky behaviors include, but are not limited to, looking at a cell phone, turning the head to the side for more than a predetermined period of time, closing the eyes for more than a predetermined period of time, etc. The algorithm in this specification may be, but is not limited to, a computer vision algorithm using artificial intelligence (AI) or machine learning (ML).

[0022] The concentration analysis unit 434 is configured to obtain an alcohol concentration value based on the third sensing data generated by the alcohol sensor 423.

[0023] When the warning control unit 435 determines that any one of the warning conditions is met based on the sensing data set, it is configured to obtain one warning parameter corresponding to the one warning condition and output a control signal including the corresponding one warning parameter to the wheel assembly 3 via the wireless communication module 41.

[0024] More specifically, when the signal analysis unit 431 determines that the heart rate obtained satisfies a first warning condition (e.g., the heart rate is higher than a predetermined rate (e.g., 110 beats per minute)) (hereinafter referred to as the "first warning condition"), the warning control unit 435 is configured to generate a control signal including one warning parameter corresponding to the first warning condition. Different warning parameters can be set according to the range of the obtained heart rate.

[0025] The warning control unit 435 is further configured to generate a control signal including one warning parameter corresponding to the second warning condition when the signal analysis unit 431 determines that the respiratory rate obtained satisfies a second warning condition (e.g., the respiratory rate is higher than a predetermined rate (e.g., 20 breaths per minute)) (hereinafter referred to as the "second warning condition").

[0026] The first warning condition for the heart rate and the second warning condition for the respiratory rate may be set by the driver or may be set according to the gender or age of the driver, but the present invention is not limited to this.

[0027] The warning control unit 435 is further configured to generate a control signal including one warning parameter corresponding to the third warning condition when the behavior of the human body image portion (i.e., the driver's behavior) determined by the behavior analysis unit 433 meets a third warning condition (hereinafter referred to as the "third warning condition") (e.g., the driver's behavior meets any one of the above-mentioned dangerous behaviors).

[0028] The warning control unit 435 is further configured to generate a control signal including one warning parameter corresponding to the fourth warning condition when it determines that the alcohol concentration value obtained by the concentration analysis unit 434 satisfies a fourth warning condition (for example, the alcohol concentration value is higher than a predetermined value (for example, 0.15 mg / L)) (hereinafter referred to as the "fourth warning condition"). The fourth warning condition may be set according to the traffic laws of the country in which the vehicle is traveling, but the present invention is not limited thereto. Furthermore, the warning parameter here may also be set to a different parameter depending on the range of the obtained alcohol concentration value.

[0029] The alert control module 43 may be implemented using, but is not limited to, a system on a chip (SoC), a microcontroller, or the like, and may include a central processing unit (CPU) and memory for storing a software application. The software application includes instructions that, when executed by the CPU, cause the CPU to perform the operations of the alert control module 43 described above. In some embodiments, the CPU can function as the signal analysis unit 431, the image analysis unit 432, the behavior analysis unit 433, the concentration analysis unit 434, and the alert control unit 435 by executing different portions of the software application. In some embodiments, each unit of the alert control module 43 may be implemented using hardware elements, software elements, or a combination of both. Examples of hardware elements may include a processor, a microprocessor, an electrical circuit, an integrated circuit, an application-specific integrated circuit (ASIC), a programmable logic circuit (PLD), a digital signal processor (DSP), a field-programmable gate array (FPGA), a logic gate, a semiconductor device, a chip, a microchip, a chipset, etc.

[0030] The wheel assembly 3 includes a wheel 31 on which a tire can be mounted, a lighting module 32, a power generation mechanism 33, a tire pressure gauge 34, and a lighting control module 35. The lighting module 32, the power generation mechanism 33, the tire pressure gauge 34, and the lighting control module 35 are disposed on the wheel 31. The lighting control module 35 is electrically connected to the lighting module 32, the power generation mechanism 33, and the tire pressure gauge 34.

[0031] The wheel 31 includes a wheel body 311 attached to an axle (not shown) of the vehicle body 800, and a plurality of decorative plates 315 arranged on the wheel 311. The wheel body 311 includes a hub 312 attached to the axle, a rim 313 spaced radially from the hub 312 and coaxially surrounding the outer circumferential surface of the hub 312, and a plurality of spokes 314 spaced apart from one another and connecting the outer circumferential surface of the hub 312 to the inner circumferential surface of the rim 313. The outer circumferential surface of the hub 312 faces the inner circumferential surface of the rim 313. The decorative plates 315 are arranged on each spoke 314 and are arranged on the side of the wheel 311 facing away from the vehicle.

[0032] The lighting module 32 includes a plurality of lighting components 321 arranged on the spokes 314 and covered by a decorative plate 315. Each of the lighting components 321 is configured to emit light in one of a plurality of color patterns under the control of the lighting control module 35 and transmit light through the corresponding decorative plate 315. Each of the lighting components 321 may be a light-emitting diode (LED), although the present invention is not limited thereto. In this embodiment, the decorative plate 315 is made of a translucent material. In some embodiments, the decorative plate 315 may be replaced with any structure that transmits light emitted by the lighting components 321, such as a flat plate with holes formed therein, although the present invention is not limited thereto.

[0033] The power generation mechanism 33 is coaxially disposed within the hub 312 of the wheel 31 and is configured to be driven by the wheel 31 to generate electric power. The electric power is provided to components disposed in the wheel body 311, including the lighting module 32, the tire pressure gauge 34, and the lighting control module 35. For details of the implementation of the power generation mechanism 33, reference may be made to the "power generation device" disclosed in U.S. Patent Application No. 18 / 610,620, "Power Generation Device," the "Power Generation Mechanism" disclosed in U.S. Patent Application No. 18 / 413,809, "Wheel Rim Device," and the "Power Generation Mechanism" disclosed in U.S. Patent Application No. 18 / 413,816, "Wheel Rim Device."

[0034] The tire pressure gauge 34 is disposed on the rim 313 of the wheel body 311 and is configured to detect the tire pressure of the tire attached to the wheel 31 to obtain a tire pressure value.

[0035] The lighting control module 35 includes a wireless communication unit 351 and a lighting control unit 352. The wireless communication unit 351 is configured to wirelessly communicate with the wireless communication module 41 of the control device 4 using a wireless communication technology (e.g., Bluetooth (registered trademark)) and to wirelessly receive control signals from the wireless communication module 41 of the control device 4.

[0036] The lighting control unit 352 may be, but is not limited to, a microcontroller circuit. The lighting control unit 352 stores a plurality of color display settings, a plurality of tire pressure conditions, and the above-mentioned warning parameters. The tire pressure conditions and the warning parameters correspond to the color display settings, respectively. When the lighting control unit 352 determines that the tire pressure value detected by the tire pressure gauge 34 meets one of the tire pressure conditions, the lighting control unit 352 is configured to obtain a color display setting corresponding to the one tire pressure condition and control the lighting component 321 to emit light in one of the color patterns based on the corresponding color display setting.

[0037] As an example, Table 1 below shows the standard tire pressure ranges (generally around 35 psi) for the front and rear tires of different vehicle models. Specifically, the difference in tire pressure ranges for the front and rear tires of each vehicle model in Table 1 is due to the difference in weight between the front and rear of the vehicle model. Furthermore, tire pressure may also be affected by changes in the volume of gas inside the tire due to seasonal variations (e.g., winter and summer). Therefore, the tire pressure condition value must be set taking the above factors into consideration. Generally speaking, to accommodate various vehicle models and scenarios, the tire pressure condition of the present invention is set so that, for example, when the tire pressure is higher than 45 psi or lower than 25 psi (i.e., when the tire pressure is too high or too low), the lighting component 321 is controlled to emit a red light as a warning. That is, a tire pressure condition corresponding to a tire pressure higher than 45 psi is a red light, and a tire pressure condition corresponding to a tire pressure lower than 25 psi is also a red light. The present invention is not limited to this. [Table 1] The lighting control unit 352 is further configured to obtain one of the warning parameters included in the control signal received by the wireless communication unit 351, obtain one color display setting corresponding to the obtained one of the warning parameters, and control the lighting component 321 to emit light in one of the color patterns based on the corresponding one color display setting.

[0038] In this embodiment, the lighting control module 35 is configured to first control the lighting components 321 to emit light in one of the color patterns based on the tire pressure value, and in response to receiving a control signal including one of the warning parameters, to alternatively control the lighting components 321 to emit light in one of the color patterns based on the control signal. In some embodiments, the lighting control module 35 is configured to control the lighting components 321 to emit light alternately based on the tire pressure value and the control signal. Note that the present invention is not limited to the above embodiments.

[0039] When the wheel system 200 of the present invention is mounted on a vehicle body 800 and used, the power generation mechanism 33 of the wheel assembly 3 is driven to rotate while the vehicle is running, generating and supplying electricity to the wheel assembly 3. The tire pressure gauge 34 continuously obtains tire pressure values, and when the lighting control module 35 determines that the tire pressure value obtained by the tire pressure gauge 34 meets one of the tire pressure conditions, it controls the lighting component 321 to emit light in one of the color patterns based on one color display setting corresponding to the one tire pressure condition. This allows the wheel 31 to emit light to warn nearby people and vehicles.

[0040] Furthermore, the millimeter wave sensor 421, the imaging device 422, and the alcohol sensor 423 of the control device 4 perform detection related to the driver (or the driver's seat) and generate a sensing data set. If the warning control module 43 determines that any one of the warning conditions is met based on the sensing data set, it generates a control signal including one warning parameter corresponding to the one warning condition and outputs the control signal to the wireless communication unit 351 via the wireless communication module 41. Then, the lighting control module 35 of the wheel assembly 3 controls the lighting component 321 to emit light in one of the color patterns based on the control signal, so that the wheel 31 can emit light to warn surrounding people and vehicles.

[0041] 3 to 5, a method for indicating the driver's state of a vehicle according to one embodiment of the present invention is provided. The method is executed by the wheel system 200 mounted on the vehicle body 800 and is used to detect the driver's state and output a warning when the driver's state is abnormal. The method includes steps 901 to 904.

[0042] In step 901, the sensing module 42 of the control device 4 performs detection related to a target object (e.g., a driver or a driver's seat) to generate a sensing data set. The sensing data set relates to at least one of a heart rate, a breathing rate, an alcohol concentration value, a blink frequency, a blink count, an eye movement trajectory, a mouth opening, a head rotation angle, a head rotation duration, a head rotation frequency, and whether the driver's gaze is focused on the road or away from the road for a long period of time.

[0043] In step 902, if it is determined that any one of the warning conditions is met based on the sensing data set, the warning control module 43 generates a control signal including a corresponding one of the warning parameters and outputs the control signal to the lighting control module 35.

[0044] In step 903, the lighting control module 35 receives a control signal from the warning control module 53 and identifies a corresponding warning parameter contained in the control signal.

[0045] In step 904, the lighting control module 35 controls the lighting module 32 to emit light in a color pattern (e.g., red light) corresponding to a corresponding warning parameter included in the control signal, and warns surrounding people and vehicles with the emitted light.

[0046] In summary, according to the present invention, the wheel system 200 performs detection related to a target object (e.g., a driver) in the interior space 801 while the vehicle is moving to generate a sensing data set, and if it determines that one of the warning conditions is met based on the sensing data set, it controls the wheel assembly 3 to emit light in one of the color patterns. Therefore, the emitted light can warn surrounding people and vehicles and prevent them from approaching the vehicle, thereby reducing the possibility of a traffic accident. Specifically, the surrounding people can be, for example, pedestrians or drivers of other vehicles, motorcycles, or bicycles.

[0047] In one embodiment, the wireless communication module 41 of the control device 4 and the wireless communication unit 351 of the wheel assembly 3 are circuits that use ultra-wideband (UWB) wireless communication technology and operate in a frequency range of 31 MHz to 88 MHz, with a fractional bandwidth, or the bandwidth relative to the center frequency, greater than 20%. This frequency range is typically a spectrum reserved for the military, and since the center frequency is related to the sensitivity of the sensor and the maximum penetration depth of the emitted UWB signal, this frequency range can be applied to vehicles with thicker armor, such as military trucks, armored vehicles, and wheeled vehicles.

[0048] In another embodiment, the wireless communication module 41 of the control device 4 and the wireless communication unit 351 of the wheel assembly 3 are circuits that use ultra-wideband (UWB) wireless communication technology and operate in a frequency range of 3.1 GHz to 10.6 GHz, with a fractional bandwidth (i.e., the bandwidth relative to the center frequency) greater than 10%. This frequency range is a spectrum commonly used in civilian applications, and the center frequency is related to the resolution of the sensor and affects the size of the wireless receiver. Therefore, this frequency range can be applied to civilian cars, trucks, sport utility vehicles, and other vehicles that are generally not affected by the size of the antenna and receiving module.

Furthermore, in the description of "one embodiment" or "an embodiment" herein, all references to an ordinal number or other designation should be understood to include specific aspects, structures, and features of the present invention.
