Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to a driver health monitoring system, method, and vehicle. Background Technology

[0002] As living standards improve, people's demand for health management is increasing. Traditional health monitoring devices (such as body fat scales and smart bracelets) require active user operation, resulting in low usage frequency and complex operation.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: as a frequently used means of transportation, vehicles provide users with a potential scenario for seamless and continuous health monitoring, but for drivers, the focus is mostly on fatigue driving monitoring, making it difficult to monitor the driver's health. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a driver health monitoring system, method, vehicle, device, and computer-readable medium capable of monitoring the health of a driver in a vehicle.

[0005] A driver health monitoring system includes a tire pressure sensor installed inside the tire, a first bioelectric probe set on the steering wheel, a second bioelectric probe set on the pedal, and a microcontroller. The tire pressure sensor, in response to a driver's instruction to get into the vehicle, collects the tire pressure after the driver gets into the vehicle, and in response to a driver's instruction to get out of the vehicle, collects the tire pressure after the driver gets out of the vehicle. The first bioelectric probe responds to the driver's instructions to operate the vehicle and collects the bioelectrical impedance of the driver's hand; The second bioelectric probe collects bioelectrical impedance data from the driver's feet; The microcontroller uses the tire pressure after the driver gets in the vehicle, the tire pressure after the driver gets out of the vehicle, the bioelectrical impedance of the hand, and the bioelectrical impedance of the foot to analyze the driver's health parameters, and displays and pushes a health report based on the driver's health parameters in the vehicle system interface.

[0006] It also includes a pressure sensor located in the driver's seat and a sensor in the driver's door; The pressure sensor is used to collect the pressure signal of the driver's seat in real time and send the pressure signal to the microcontroller; The driver's door sensor is used to collect the opening status of the driver's door in real time and send the status of the driver's door to the microcontroller; When the microcontroller receives a pressure signal indicating that the pressure exceeds a set pressure threshold and receives a status indication that the driver's door is closed and the vehicle speed is less than a preset speed threshold, it sends the driver's entry instruction to the tire pressure sensor. When the microcontroller receives a pressure signal indicating that the pressure is less than a set pressure threshold and receives a status indication that the driver's door is open, it sends the driver's exit instruction to the tire pressure sensor.

[0007] The first bioelectric probe includes: a left-hand bioelectric probe disposed on the left side of the steering wheel for collecting the bioelectrical impedance of the driver's left hand and a right-hand bioelectric probe disposed on the right side of the steering wheel for collecting the bioelectrical impedance of the driver's right hand. And / or, The second bioelectric probe includes: a left foot bioelectric probe installed on the driver's footrest for collecting the bioelectrical impedance of the driver's left foot and a right foot bioelectric probe installed on the brake pedal for collecting the bioelectrical impedance of the driver's right foot; And / or, Both the first and second bioelectric probes are equipped with multiple frequencies, and the operating frequencies of the first and second bioelectric probes are the same.

[0008] When the microcontroller receives a pressure signal indicating that the pressure exceeds the set pressure threshold and the vehicle speed is zero, it controls the vehicle system interface to display a prompt message to remind the driver to keep the skin of their hands and feet in contact with the bioelectric probe.

[0009] It also includes health sensors disposed on the steering wheel, the health sensors including one or more of an optical heart rate sensor, a blood oxygen sensor, a skin temperature sensor, and a blood pressure sensor; The microprocessor is further used to analyze and obtain the driver's health parameters using the tire pressure after the driver gets in the vehicle, the tire pressure after the driver gets out of the vehicle, the bioelectrical impedance of the hand, the bioelectrical impedance of the foot, and the sensor parameters of the driver collected by the one or more sensors.

[0010] It also includes: a driver's cab camera located near the steering wheel; When the microcontroller receives a pressure signal indicating that the pressure exceeds the set pressure threshold, it sends a driver identification message to the cab camera and displays a reminder message for the captured image on the vehicle system interface. The driver's cab camera captures an image of the driver and sends the image to the microcontroller, which then successfully authenticates the driver's image using the stored image.

[0011] The microcontroller establishes a weight model based on the historical tire pressure and the driver's historical weight, and determines the driver's current weight using the tire pressure after the driver gets in the vehicle and the tire pressure after the driver gets out of the vehicle. The driver's multiple historical weights are smoothed by using sliding window averaging or Kalman filtering to obtain the processed driver's weight. Using the driver's weight after the treatment, the bioelectrical impedance of the hand, and the bioelectrical impedance of the foot, the driver's health parameters are analyzed and obtained. The driver's health parameters include one or more of the following: total body water, total protein mass, total inorganic salt mass, total body fat mass, body fat percentage, BMI index, basal metabolic rate, bone density, physiological age, and heart rate.

[0012] In response to the health report display instruction, the microcontroller displays a health report of the measured health parameters in the vehicle system interface, and establishes and displays a historical health report based on the weights corresponding to the measured health parameters and the weights corresponding to historical health parameters. The weights are determined based on the signal-to-noise ratio and duration corresponding to the health parameters. The health report of the measured health parameters and the historical health report are pushed to the mobile terminal application.

[0013] According to a second aspect of the present invention, a method for monitoring driver health is provided, comprising: A tire pressure sensor installed inside the tire collects the tire pressure after the driver gets into the vehicle in response to a driver's instruction to get in, and collects the tire pressure after the driver gets out of the vehicle in response to a driver's instruction to get out. The first bioelectric probe, located on the steering wheel, responds to the driver's vehicle operation instructions and collects the bioelectrical impedance of the driver's hand. A second bioelectric probe, located at the pedal, collects bioelectrical impedance data from the driver's foot. The driver's health parameters are analyzed using the tire pressure after the driver gets in the vehicle, the tire pressure after the driver gets out of the vehicle, the bioelectrical impedance of the hand, and the bioelectrical impedance of the foot. The health report based on the driver's health parameters is then displayed and pushed to the vehicle system interface.

[0014] According to a third aspect of the present invention, a vehicle is provided, including the driver health monitoring system described above.

[0015] According to a fourth aspect of the present invention, a driver health monitoring electronic device is provided, comprising: One or more processors; Storage device for storing one or more programs. When the one or more programs are executed by the one or more processors, the one or more processors perform the methods described above.

[0016] According to a fifth aspect of the present invention, a computer-readable medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method as described above.

[0017] One embodiment of the above invention has the following advantages or beneficial effects: Tire pressure sensors are used to collect tire pressure data when the driver gets in and out of the vehicle. Bioelectrical impedance analysis of the driver's hands and feet is collected using bioelectrical probes located on the steering wheel and pedals. Based on these health parameters, health reports can be displayed and pushed to the vehicle's infotainment system interface, enabling monitoring of the driver's health within the vehicle.

[0018] The further effects of the aforementioned unconventional alternative methods will be explained below in conjunction with specific implementation methods. Attached Figure Description

[0019] The accompanying drawings are provided to better understand the invention and are not intended to unduly limit the scope of the invention. Wherein: Figure 1 This is a schematic diagram of the main structure of a driver health monitoring system according to an embodiment of the present invention; Figure 2 This is a schematic diagram of a bioelectric probe according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the main steps of the driver health monitoring method according to an embodiment of the present invention; Figure 4 This is an exemplary system architecture diagram in which embodiments of the present invention can be applied; Figure 5 This is a schematic diagram of the structure of a computer system suitable for implementing terminal devices or servers of the present invention. Detailed Implementation

[0020] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0021] Currently, most common health management systems rely on dedicated body composition detection devices (such as body fat scales) or smart wearable devices. Whether it's data measurement, processing, or recording, users need to actively and periodically trigger operations. This results in the following limitations: investment in dedicated equipment and systems (body fat scales, smart wearable devices, mobile app memberships); low usage frequency; and discontinuous data recording, making it easy to miss data points.

[0022] Vehicle health functions are mostly focused on scenarios such as fatigue driving monitoring and driver relaxation, lacking in-depth detection and analysis of driver health conditions. In particular, the intelligent connectivity of automobiles in recent years has provided favorable conditions for realizing this scenario.

[0023] To monitor the driver's health, the following technical solutions from the embodiments of the present invention can be adopted.

[0024] See Figure 1 , Figure 1 This is a schematic diagram of the main structure of a driver health monitoring system according to an embodiment of the present invention.

[0025] The tire pressure sensor A is installed inside the tire; the bioelectric probes B1 and B2 are installed in the steering wheel; and the bioelectric probe C is installed at the pedal. Figure 1 (Not shown) and microcontroller.

[0026] Specifically, tire pressure sensor A is installed directly inside each tire. For example, it can be installed inside the tire valve stem or fixed to the rim using a special clamp, located within the sealed space formed by the tire and rim. Each tire pressure sensor A independently measures the absolute pressure inside the tire and then transmits the data wirelessly to a receiver inside the vehicle. Existing tire pressure monitoring systems (TPMS) only utilize tire pressure sensor A for tire safety warnings, failing to explore its potential application value.

[0027] As a vehicle component that drivers inevitably come into contact with, the steering wheel is an ideal location for integrating sensors. Figure 2 The bioelectric probes are installed on the steering wheel and pedals respectively. Specifically, the left-hand bioelectric probe B1 is installed on the left side of the steering wheel, and the right-hand bioelectric probe B2 is installed on the right side of the steering wheel. Figure 2 The gray pedal on the lower left is the driver's footrest. Figure 2 The white pedal on the lower right is the brake pedal. A left-foot bioelectric sensor C1 is located on the driver's footrest, and a right-foot bioelectric sensor C2 is located on the brake pedal.

[0028] In addition, a microcontroller is installed in the vehicle to process the parameters collected by the tire pressure sensor and the bioelectric probe.

[0029] In one embodiment of the present invention, tire pressure sensor A collects tire pressure when it receives a driver's instruction to get in the vehicle, and also collects tire pressure when it receives a driver's instruction to get out of the vehicle. The tire pressure increases due to the increased total weight of the vehicle after the driver gets in, and decreases due to the decreased total weight of the vehicle after the driver gets out. The tire pressure is measured by the tire pressure sensor in both of these situations.

[0030] Additionally, upon receiving instructions from the driver to operate the vehicle, with both hands on the steering wheel, bioelectrical impedance data of the driver's hands is collected using bioelectrical probes located on the steering wheel. With both feet on the pedals, bioelectrical impedance data of the driver's feet is collected using bioelectrical probes located on the pedals.

[0031] The microcontroller analyzes tire pressure measured by a tire pressure sensor under two conditions, and bioelectrical impedance analysis of the driver's hands and feet collected by a bioelectrical probe, to obtain health parameters. It can also display the health report on the vehicle's infotainment system interface, such as the central control display. Furthermore, the vehicle can push these health reports to mobile devices linked to the vehicle via a cloud server.

[0032] In the above embodiments, existing tire pressure sensors in the vehicle are reused, and bioelectric probes are added to the steering wheel and pedals, ensuring that measurements can be completed while the driver is in a normal driving grip posture, achieving non-invasive data collection. Data collection is completed inside the vehicle without driver intervention, increasing the frequency and continuity of data collection and enabling monitoring of driver health. Furthermore, health reports can be generated based on the sensor measurement parameters, allowing for in-depth analysis of test parameters and further improving the reliability of health monitoring. This approach is low-cost and easy to implement.

[0033] In one embodiment of the invention, a driver's seat pressure sensor is installed in the driver's seat. Changes in pressure from the driver's seat pressure sensor determine whether the driver's seat is supporting the driver. A driver's door sensor is installed in the driver's side door. The driver's door is the door on the driver's side, such as in vehicles where the steering wheel is located on the left side of the driver's cabin. The driver's door is the left front door. The driver's door sensor determines whether the driver's door is closed or open. The driver's seat pressure sensor and the driver's door sensor can send signals to a microcontroller, which then sends relevant instructions.

[0034] Signals collected by the driver's seat pressure sensor and the driver's side door sensor are used to determine the indication to be sent to the tire pressure sensor. The pressure sensor is used to collect the pressure signal of the driver's seat in real time and send the pressure signal to the microcontroller; the driver's side door sensor is used to collect the open status of the driver's side door in real time and send the status of the driver's side door to the microcontroller.

[0035] When the microcontroller receives a pressure signal indicating that the pressure exceeds a set pressure threshold, and receives a status indication that the driver's door is closed and the vehicle speed is less than a preset speed threshold, it sends a driver entry instruction to the tire pressure sensor. The tire pressure is then collected by the tire pressure sensor after the driver enters the vehicle.

[0036] When the microcontroller receives a pressure signal indicating that the pressure is below a set pressure threshold and receives a status indication that the driver's door is open, it sends a driver exit instruction to the tire pressure sensor. The tire pressure is then collected by the tire pressure sensor after the driver exits the vehicle.

[0037] In the above embodiments, a driver's seat pressure sensor and a driver's door sensor are used to determine whether the driver's seat is under load and whether the driver's door is open, so as to improve the timeliness and accuracy of tire pressure measurement.

[0038] In one embodiment of the invention, the bioelectric probe is triggered based on a driver's vehicle operation instruction. When the driver is operating the vehicle, they send a vehicle operation instruction. For example, operating the vehicle includes one or more of the following: operating the steering wheel, operating the gear shift, operating the brake pedal, or operating the accelerator pedal.

[0039] Figure 2 Two bioelectrical probes are installed on the steering wheel. Bioelectrical probe B1 is located between the 7 o'clock and 9 o'clock positions on the steering wheel and is used to monitor the driver's left hand. Bioelectrical probe B2 is located between the 3 o'clock and 5 o'clock positions on the steering wheel and is used to monitor the driver's right hand. Bioelectrical probes B1 and B2 are used to establish bioelectrical impedance circuits for the driver's two hands. This allows the left-hand bioelectrical probe to collect the bioelectrical impedance of the driver's left hand, and the right-hand bioelectrical probe to collect the bioelectrical impedance of the driver's right hand.

[0040] Two bioelectric probes are installed at the driver's footrest and brake pedal, respectively. Bioelectric probe C1, located on the footrest, monitors the driver's left foot. Bioelectric probe C2, located on the brake pedal, monitors the driver's right foot, thus establishing a bioelectrical impedance circuit for both feet. This achieves the goal of collecting the bioelectrical impedance of the driver's left foot using the left foot bioelectric probe and collecting the bioelectrical impedance of the driver's right foot using the right foot bioelectric probe. The bioelectrical impedance Z is a complex number comprising resistance (R) and reactance (Xc).

[0041] Each bioelectric probe can serve as both a microcurrent excitation electrode and a detection electrode, employing multi-channel electrical signal acquisition to eliminate acquisition errors. In addition to fixed frequencies (e.g., 50kHz, 500µA), multiple frequencies can be used, utilizing characteristic currents at various frequencies (e.g., 5kHz, 10kHz, 50kHz, 100kHz) to obtain richer bioelectrical information and improve estimation accuracy. A low-frequency current of 5kHz can barely penetrate the cell membrane lipid bilayer, its path confined to the extracellular fluid. A high-frequency current of 100kHz can penetrate the cell membrane, flowing through both intracellular and extracellular fluids. By measuring the impedance at multiple frequencies, the volumes of extracellular and intracellular fluids can be calculated separately, thereby improving the accuracy of impedance measurement.

[0042] Specifically, multiple frequencies are set for the bioelectric probe installed on the steering wheel, and multiple frequencies are also set for the bioelectric probe installed on the pedals. The bioelectric probes on the steering wheel and the pedals are set to the same frequency. The bioelectric probe on the steering wheel uses multiple raised or arrayed electrode points to increase the probability of contact with the skin of the hand. The conductive area of ​​the bioelectric probe on the pedals is increased to improve its sensitivity.

[0043] In one embodiment of the present invention, to improve the accuracy of the signals acquired by the bioelectric probe, when the microcontroller receives a pressure signal indicating that the pressure exceeds a set pressure threshold and the vehicle speed is zero, it controls the vehicle's infotainment system interface to display a prompt message to remind the driver to keep their hands and feet in contact with the bioelectric probe with bare skin. The prompt message serves to remind the driver to remove gloves and socks, and to ensure that their hands and feet are in contact with the bioelectric probe with bare skin.

[0044] Figure 2 A sensor D is located on the lower right side of the steering wheel. Sensor D may include one or more of the following: an optical heart rate sensor, a blood oxygen sensor, a skin temperature sensor, and a blood pressure sensor. Sensor D can replace the data collection function of wearable smart devices. This allows for in-vehicle monitoring of the driver's health using the steering wheel and pedals. Sensor D, positioned in the steering wheel grip area, can collect heart rate, blood oxygen levels, body temperature, and blood pressure data imperceptibly.

[0045] In analyzing the driver's health parameters, sensor D is set up to collect the driver's sensor parameters, tire pressure collected by the tire pressure sensor, and bioelectrical impedance, and the driver's health parameters are obtained through analysis.

[0046] The vehicle's driver is not fixed; each driver can be monitored. Drivers can be identified using a cab camera located near the steering wheel and a driver's seat pressure sensor.

[0047] Specifically, when the microcontroller receives a pressure signal indicating that the pressure exceeds a set threshold, it sends a driver authentication message to the driver's cab camera. Simultaneously, it displays an image acquisition reminder message on the vehicle's infotainment system interface, such as: Image Acquisition Reminder: Please face the driver's cab camera.

[0048] The driver's cab camera captures images of the driver and sends them to the microcontroller. The microcontroller successfully authenticates the driver image using the stored images. For example, if the microcontroller stores images of Driver 1 and Driver 2, and the driver image matches Driver 1, the authentication is successful. If the driver image differs from both Driver 1 and Driver 2, the authentication fails. The microcontroller can then use these driver images as Driver 3 and create a corresponding health report for Driver 3.

[0049] The microcontroller is linked to the sensors of the driver health monitoring system and receives parameters collected by multiple sensors.

[0050] For tire pressure measured by tire pressure sensors, the microcontroller establishes a weight model formula 1 based on historical tire pressure and historical driver weight.

[0051]

[0052] Formula 1

[0053] W user is the driver's current weight, in kg. K The calibration constant is the fitting coefficient between the tire pressure sensor pressure and the driver's weight, obtained from calibration experimental data, and is related to the tire and vehicle suspension characteristics. C The calibration coefficients are environmental temperature and levelness coefficients obtained through calibration time, used to correct calculation errors. g is the gravitational constant. Pi It is the tire pressure after the driver gets into the car. Pi c It is the tire pressure after the driver gets out of the car.

[0054] The microcontroller uses the tire pressure after the driver gets in the vehicle and the tire pressure after the driver gets out of the vehicle to determine the driver's current weight using Formula 1.

[0055] Considering the impact of vehicle weight variations on driver weight measurement, such as changes in fuel tank level, a sliding window averaging or Kalman filter is used to smooth multiple historical driver weights, resulting in a processed driver weight. This eliminates the influence of short-term vehicle weight fluctuations on driver weight, yielding a stable and accurate driver weight.

[0056] The driver's health parameters were obtained by analyzing the driver's weight, hand bioelectrical impedance, and foot bioelectrical impedance after treatment.

[0057] The following sections describe the health parameters for drivers.

[0075] BMI Body fat percentage, in kg / m² 2 . Wuser The driver's weight is expressed in kg. H The driver's height is in meters (m).

[0076] Basal metabolic rate:

[0077] Formula 8

[0078] BMR Basal metabolic rate, expressed in kcal / day. Wuser is the driver's weight, expressed in kg. H The driver's height is in meters (m). Age For drivers and their age. CFor the error compensation constant, C=5 for males and C=-161 for females.

[0088] Blood oxygen content, body temperature, and blood pressure can be converted from analog to digital values ​​based on parameters collected by blood oxygen sensors, skin temperature sensors, and blood pressure sensors, and then processed into the absolute values ​​that need to be presented.

[0089] In one embodiment of the present invention, the microcontroller constructs a health report based on the driver's health parameters obtained through analysis. In response to a health report display instruction, the health report is displayed on the vehicle's infotainment system interface and pushed to a mobile terminal associated with the vehicle. The health report includes a report on the currently measured health parameters and historical health reports. The health report display instruction can be sent by the driver through the vehicle's infotainment system interface or the mobile terminal.

[0090] Specifically, after measuring the driver's health parameters using sensors in the vehicle, the system stores the current health parameters as well as historical health parameters. A health report is then generated based on the current health parameters.

[0091] A historical health report can also be constructed using the health parameters measured in the current and historical measurements. The weight of each health parameter measurement is determined by its signal-to-noise ratio and duration. For example: the weight of the first body fat percentage measurement is 0.3; the weight of the second body fat percentage measurement is 0.3; the weight of the current body fat percentage measurement is 0.4 because its signal-to-noise ratio and duration are both greater than those of the first and second measurements. The historical health report is constructed using these three measurements and their corresponding weights. The historical health report includes trend charts of the health parameters and health recommendations.

[0092] When the health report is displayed on the vehicle infotainment system interface, the current health report and historical health reports can be sent to the mobile terminal associated with the vehicle infotainment system via a cloud server connected to the vehicle infotainment system.

[0093] In the above embodiments, parameters measured by tire pressure sensors, bioelectric probes, and other sensors are used to determine the driver's health parameters more accurately than from a single data source. Continuous monitoring generates health reports. The vehicle connects to a cloud server and a mobile app to form a personal health data center, providing a data foundation for subsequent access to medical services, fitness plans, and more.

[0094] In the embodiments of the present invention described above, the automobile is upgraded from a means of transportation into a mobile health management platform. Through seamless and automated data collection, driver compliance is addressed, enabling continuous monitoring of health indicators. By collecting health parameters through sensors within the vehicle, a more convenient and data-continuous health management solution is provided compared to traditional home devices and wearable devices. This solution is particularly suitable for health-conscious but busy modern individuals, possessing enormous market potential and social value.

[0095] See Figure 3 , Figure 3 This is a schematic diagram of the main flow of a driver health monitoring method according to an embodiment of the present invention, specifically including: S301. A tire pressure sensor installed inside the tire, which, in response to a driver's instruction to get in the vehicle, collects the tire pressure after the driver gets in the vehicle, and in response to a driver's instruction to get out of the vehicle, collects the tire pressure after the driver gets out of the vehicle.

[0096] The tire pressure sensor is installed inside the tire, the first bioelectric probe is set in the steering wheel, the second bioelectric probe is set in the pedal, and a microcontroller is installed. In one embodiment of the present invention, the pressure sensor is used to acquire pressure signals from the driver's seat in real time and send the pressure signals to the microcontroller; The driver's door sensor is used to collect the opening status of the driver's door in real time and send the status of the driver's door to the microcontroller; When the microcontroller receives a pressure signal indicating that the pressure exceeds a set pressure threshold and receives a status indication that the driver's door is closed and the vehicle speed is less than a preset speed threshold, it sends the driver's entry instruction to the tire pressure sensor. When the microcontroller receives a pressure signal indicating that the pressure is less than a set pressure threshold and receives a status indication that the driver's door is open, it sends the driver's exit instruction to the tire pressure sensor.

[0097] In one embodiment of the present invention, a driver's cab camera is disposed near the steering wheel; When the microcontroller receives a pressure signal indicating that the pressure exceeds the set pressure threshold, it sends a driver identification message to the cab camera and displays a reminder message for the captured image on the vehicle system interface. The driver's cab camera captures an image of the driver and sends the image to the microcontroller, which then successfully authenticates the driver's image using the stored image.

And / or, The second bioelectric probe includes: a left foot bioelectric probe installed on the driver's footrest for collecting the bioelectrical impedance of the driver's left foot and a right foot bioelectric probe installed on the brake pedal for collecting the bioelectrical impedance of the driver's right foot; And / or, Both the first and second bioelectric probes are equipped with multiple frequencies, and the operating frequencies of the first and second bioelectric probes are the same.

[0100] In one embodiment of the present invention, when the microcontroller receives a pressure signal indicating that the pressure exceeds a set pressure threshold and the vehicle speed is zero, it controls the vehicle system interface to display a prompt message to remind the driver to keep the skin of their hands and feet in contact with the bioelectric probe.

[0101] S303. Using the tire pressure after the driver gets into the vehicle, the tire pressure after the driver gets out of the vehicle, the bioelectrical impedance of the hand, and the bioelectrical impedance of the foot, the driver's health parameters are analyzed and obtained, and a health report based on the driver's health parameters is displayed and pushed in the vehicle system interface.

[0102] In one embodiment of the present invention, a health sensor disposed on the steering wheel is further included, the health sensor including one or more of an optical heart rate sensor, a blood oxygen sensor, a skin temperature sensor, and a blood pressure sensor; The microprocessor is further used to analyze and obtain the driver's health parameters using the tire pressure after the driver gets in the vehicle, the tire pressure after the driver gets out of the vehicle, the bioelectrical impedance of the hand, the bioelectrical impedance of the foot, and the sensor parameters of the driver collected by the one or more sensors.

[0103] In one embodiment of the present invention, the microcontroller establishes a weight model based on the historical tire pressure and the historical driver weight, and determines the driver's current weight using the tire pressure after the driver gets into the vehicle and the tire pressure after the driver gets out of the vehicle. The driver's multiple historical weights are smoothed by using sliding window averaging or Kalman filtering to obtain the processed driver's weight. Using the driver's weight after the treatment, the bioelectrical impedance of the hand, and the bioelectrical impedance of the foot, the driver's health parameters are analyzed and obtained. The driver's health parameters include one or more of the following: total body water, total protein mass, total inorganic salt mass, total body fat mass, body fat percentage, BMI index, basal metabolic rate, bone density, physiological age, and heart rate.

[0104] In one embodiment of the present invention, the microcontroller, in response to a health report display instruction, displays a health report of the current measured health parameters in the vehicle system interface, and establishes and displays a historical health report based on the weights corresponding to the current measured health parameters and the weights corresponding to historical health parameters, wherein the weights are determined based on the signal-to-noise ratio and duration corresponding to the health parameters. The health report of the measured health parameters and the historical health report are pushed to the mobile terminal application.

[0105] The driver health monitoring system in this embodiment of the invention can be applied to vehicles.

[0106] Figure 4 An exemplary system architecture 400 for which the driver health monitoring method or driver health monitoring system of the present invention can be applied is shown.

[0107] like Figure 4 As shown, the vehicle system architecture 400 may include various systems, such as a driving control system 401, a power system 402, a sensor system 403, a control system 404, a lane change assist system 405, one or more peripheral devices 406, a power supply 407, a computer system 408, and a user interface 409. The driver health monitoring method provided in this embodiment can be implemented through interaction with the aforementioned systems, or through control of the systems by external devices, or through operation of the systems by a robot driving the vehicle. Optionally, the vehicle system architecture 400 may include more or fewer systems, and each system may include multiple components. Furthermore, each system and component of the vehicle system architecture 400 may be interconnected via wired or wireless means.

[0108] The vehicle system architecture 400 includes a driving control system 401, which can be in a fully or partially automated driving mode. For example, the driving control system 401 can automatically control the vehicle's movement based on control signals or control commands without human interaction, interaction with external devices, or interaction with a robot driving the vehicle.

[0109] Sensor system 403 may include sensors for sensing the vehicle's surrounding environment (such as sensors for detecting the presence of obstacles) and pressure sensors for sensing the presence of passengers in the seats. Examples include a positioning system (which may be a Global Positioning System (GPS), BeiDou Navigation Satellite System, or other positioning systems), radar, a laser rangefinder, an inertial measurement unit (IMU), and cameras. The positioning system can be used to determine the vehicle's geographical location. The IMU is used to sense changes in the vehicle's position and orientation based on inertial acceleration. In one embodiment, the IMU may be a combination of an accelerometer and a gyroscope. Radar can use radio signals to sense objects in the vehicle's surrounding environment. In some embodiments, in addition to sensing objects, radar can also be used to sense the speed and / or direction of travel of objects.

[0110] To detect environmental information and objects outside the vehicle, cameras can be configured at appropriate locations on the vehicle's exterior. For example, to acquire environmental images of the vehicle's sides, a camera can be mounted on the side mirror. The camera can be a still or video camera.

[0111] The control system 404 may include software systems for implementing vehicle driving control, such as systems for analyzing the vehicle's surrounding environment, pretensioning seat belts, route planning, obstacle avoidance, and image analysis. The control system 404 may also include hardware systems such as an accelerator, steering wheel system, seat belt system, airbag system, and peripheral devices (such as projection equipment and displays). Furthermore, the control system 404 may add or replace components other than those shown and described. Alternatively, some of the components shown above may be reduced.

[0112] In addition, the control system 404 can also interact with external sensors, other autonomous driving devices, other computer systems, or users via peripheral devices 406. Peripheral devices 406 may include wireless communication systems, on-board computers, microphones and / or speakers, cameras, and projectors, etc.

[0113] In some embodiments, peripheral device 406 provides a means for user interaction with the control system 404 via a user interface. For example, an onboard computer may provide information to a user of the vehicle. The user interface may also operate the onboard computer to receive user input. The onboard computer may be operated via a touchscreen. In other cases, peripheral device may provide a means for communicating with other devices located within the vehicle. For example, a microphone may receive audio (e.g., voice commands or other audio input) from a user of the control system. Similarly, a speaker may output audio to a user of the control system.

[0114] Wireless communication systems can communicate wirelessly with one or more devices, either directly or via a communication network. For example, wireless communication systems can use networks such as cellular networks, WiFi, and wireless local area networks (WLANs), or they can use infrared links, Bluetooth, or ZigBee to communicate directly with devices. Other wireless protocols include those used in various autonomous driving communication systems.

[0115] The processor can be any conventional processor, such as a commercially available central processing unit (CPU). Alternatively, the processor can be a special-purpose device such as an application-specific integrated circuit (ASIC) or other hardware-based processor. Those skilled in the art will understand that the processor, computer, or memory can actually include multiple processors, computers, or memories that may or may not be stored in the same physical housing. For example, memory can be a hard disk drive or other storage media located in a housing different from that of a computer. Therefore, references to processors or computers will be understood to include references to a collection of processors or computers or memories that may or may not operate in parallel. Unlike using a single processor to perform the steps described herein, some components, such as steering and deceleration components, may each have their own processor that performs only determinations related to the component's specific function.

[0116] User interface 409 is used to provide information to or receive information from a user of the vehicle. Optionally, user interface 409 may include one or more input / output devices within a set of peripheral devices 406, such as wireless communication systems, on-board computers, microphones, and speakers.

A drive 510 is also connected to I / O interface 505 as needed. A removable medium 511, such as a disk, optical disk, magneto-optical disk, semiconductor memory, etc., is installed on drive 510 as needed so that computer programs read from it can be installed into storage section 508 as needed.
