Safe driving and healthcare provision system based on complex detection of hands-on information and biometric information {SYSTEM FOR PROVIDING SAFE DRIVING AND HEALTH CARE BASED ON COMBINED DETECTING OF HANDS ON AND BIO-INFORMATION}

The present invention relates to a system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information, and more particularly, complexly detecting hands-on information and biometric information for a driver from a steering wheel of a vehicle, and It is related to a safe driving and healthcare provision system based on hands-on information and biometric information complex detection that induces safe driving based on information and provides health information by continuously grasping the driver's health status.

In recent years, the automobile industry is making efforts to improve the safety of automobiles and the convenience of drivers, and to protect pedestrians. Accordingly, a system for recognizing the surrounding environment by attaching various sensors inside and outside a vehicle is generally introduced for the safety of drivers and passengers.

In particular, there are cases in which the driver is in a tired state or drowsy driving due to fatigue or lack of sleep due to long-time driving, and driving a vehicle in such a state may cause a fatal accident. Therefore, many systems are being developed to promote safe driving such as drowsy driving.

The steering wheel of a vehicle is a device that allows a driver to directly grip and manipulate the vehicle to perform steering control, and at least one hand must grip the steering wheel while the vehicle is running. In addition, the steering wheel is provided with various buttons that control the vehicle or control the driving environment in connection with the center fascia and the electronic control unit (ECU) of the vehicle.

As a technology for detecting a biological signal from a driver using such a steering wheel, a multifunctional steering wheel having a basic health information collection function has been disclosed in Patent Publication No. 10-0998032.

The technology includes electrodes for each channel (L, R) for measuring the driver's ECG (ElectroCardioGram) signal, and is equipped with a blood pressure sensor for measuring the pulse of the driver's finger blood vessels, and detected from each electrode for each channel. After analyzing the ECG signal to measure the driver's electrocardiogram, after receiving the driver's personal information from the driver, the driver's body fat is measured based on the driver's body resistance, and the driver's blood pressure based on the blood pressure measurement information detected from the blood pressure sensor. And an operation and display means for analyzing pulse rate and performing display and communication networking corresponding to each analysis result.

However, since the above technology does not have a function of detecting whether the driver holds the steering wheel, an error may be included in the information detected when the driver hands off, that is, when the driver does not grip the steering wheel.

In addition, as a technology for detecting a hands-off state of a steering wheel, an apparatus for detecting a hands-off of a driver and a method thereof are disclosed in Korean Patent Publication No. 10-2018-0069504.

The technology includes a torque sensor that measures the torque generated by the steering wheel of a quantity; A first filter for removing noise of the torque measured by the torque sensor; A vibration generator for generating reference vibration in the steering wheel of the vehicle; A second filter for extracting a torque in a vibration frequency band from the torque measured by the torque sensor; And a controller determining whether the driver's hands off based on the amount of change in the torque passing through the second filter after activating the vibration generator, if the rate of change of the torque passing through the first filter does not exceed a threshold value. It is characterized by that.

However, although the above technology can detect whether the driver grips the steering wheel, there is a disadvantage in that it is difficult to provide health information by detecting the driver's state to induce safe driving or by continuously grasping the driver's health state.

The present invention can provide health information by complexly detecting hands-on information and biometric information for a driver from a steering wheel of a vehicle, inducing safe driving based on the detected information, and continuously grasping the driver's health status. It relates to a system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information.

1 is a schematic configuration diagram of a state in which a system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information according to the present invention is applied to a vehicle, and FIG. 2 is a combination of hands-on information and biometric information according to the present invention. It is a configuration diagram of a detection-based safe driving and healthcare provision system.

Referring to FIG. 1, the system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information according to the present invention includes a hands-on detection unit 100, a bio-signal detection unit 200, a data processing unit 300, It comprises a control unit 400, a storage unit 500, an electronic control unit (ECU, 600), an alarm unit 700, and a communication unit 800.

The hands-on detection unit 100 is installed on the steering wheel 10 of a vehicle to detect whether the steering wheel is gripped.

3 is a schematic configuration diagram of a hands-on detection unit and a bio-signal detection unit of a system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information according to the present invention.

The hands-on detection unit 100 according to the present invention is configured to detect whether the driver grips the rim 11 of the steering wheel 10 and detects the gripping position.

4A is a diagram illustrating a configuration of a hands-on detection unit applied to a system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information according to the present invention, and FIG. 4B is a circuit diagram of a hands-on detection unit.

3, 4A and 4B, the hands-on detection unit 100 includes a power module 110, a positive electrode 120, a negative electrode 130, a galvanometer 140, and a gripping position detection module 150. Is composed.

The power module 110 supplies DC power, and after receiving power from a battery provided in a vehicle, converts the applied power to a voltage/current within an appropriate range allowing safety from electric shock and supplies it. Here, the voltage supplied from the power module 110 is configured to be kept constant within the range of the allowable contact voltage.

The positive electrode line 120 is connected to the (+) electrode of the power module 110 and is disposed along the rim 11 of the steering wheel 10.

The cathode ray 130 is connected to the (-) pole of the power module 110 and is disposed along the rim 11 of the steering wheel 10, and is installed in parallel with the anode line 120 at a predetermined distance. do.

At this time, by preventing the ends of the anode line 120 and cathode line 130 from being connected to each other, a closed circuit is not formed along the anode line 120 and cathode line 130 respectively connected to the power module 110. Avoid.

The galvanometer 140 is installed on the selected one of the anode line 120 or the cathode line 130 and detects a current flowing therethrough.

The gripping position detection module 150 detects a current value of the galvanometer 140 in a state in which the anode line 120 and the cathode line 130 are connected according to the grip of the steering wheel, and the steering is performed according to the detected current value. The gripping position of the wheel is detected.

The human body resistance is usually considered to be 5㏀. Accordingly, when the driver's hand grips the steering wheel 10 in a state in which the anode ray 120 and the cathode ray 130 are not in contact, the positive ray 120 and the cathode ray 130 It is connected by a resistor to form a close circuit. When the closed loop is configured, the current supplied from the power module 110 flows through the anode line 120 and the cathode line 130, and resistance and current are inversely proportional when the voltage is constant.

That is, as shown in FIG. 4A, the positive electrode 120 and the negative electrode 130 are disposed along the rim 11 of the steering wheel 10, and the driver's hand holds the rim 11 The lengths of the anode line 120 and the cathode line 130 constituting the loop are variable.

When the skin resistance and voltage of the hand are constant, the resistance becomes proportional to the length of the closed loop conductor. Also, from Ohm's Law, resistance is inversely proportional to current.

Accordingly, when the driver's hand grasps the rim 11, the length of the wire constituting the closed loop varies according to the grasping position, and when the current is detected through the galvanometer 140, not only the gripping position but also the hands-on status Also, detection becomes possible.

The gripping position may be calculated based on the length of the detection current according to the arrangement of the anode line 120 and the cathode line 130. Of course, even when the resistance to the gripping position is detected, the gripping position and whether the hands are turned on can also be detected.

In addition, the hands-on status is determined as hands-on when the galvanometer 140 detects a current greater than a set value, and is determined as hands-off when a current greater than the set value is not detected.

In general, for safe driving, it is preferable that the driver's steering wheel grip position is located at 10 o'clock and 2 o'clock with respect to the rim.

However, this criterion may vary according to the driver's driving habits, and when the detected hands-on position is different from the usual hands-on position, it may be determined that the driver's physical or psychological state is out of the normal state.

In addition, it may be configured to generate an alarm signal or the like when hands-off for a certain amount or more while the vehicle is running by linking with a speedometer of a vehicle in relation to whether hands are on or not.

Accordingly, the information detected by the hands-on detection unit 100 of the present invention has the advantage of including information related to the gripping position of the rim as well as the gripping state.

The biometric signal detection unit 200 detects biometric information from a driver of a vehicle.

To this end, the biosignal detection unit 200 of the present invention includes a first biosignal detection module 210 and a second biosignal detection module 220.

5 is a diagram showing the configuration of a bio-signal detection unit applied to a system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information according to the present invention.

Referring to FIG. 5, the first bio-signal detection module 210 is installed on the steering wheel 10 to detect biometric information from the driver under the condition of holding the steering wheel 10.

That is, when the driver grips the rim 11 of the steering wheel 10, the first bio-signal detection module 210 detects various biometric information from the driver by contact with the skin of the driver's hand and the electrode. , A body temperature sensor 211 for detecting body temperature, an electrocardiogram sensor 212 for detecting a heartbeat, and a pressure sensor 213 for detecting a gripping pressure.

The body temperature sensor 211 detects the temperature of the palm of the hand while the driver grabs the steering wheel.

In addition, the electrocardiogram sensor 212 detects the amplitude of the heart transmitted to the blood vessels and muscles distributed in the palm of the driver to detect the reaction of the living body due to changes in the autonomic nerve, and the pressure sensor 213 The magnitude of the grip force holding the rim 11 of the steering wheel 10 is detected.

Electrocardiogram (ECG) refers to an electrical change that occurs locally due to cardiac activity, and the electrical change is transmitted to tissues constituting a volume conductor and reaches the body surface, and thus can be detected in the head. That is, the electrocardiogram detects a physical motion that contracts and relaxes by electrical activity occurring inside the heart as an electrical signal, and is generally distributed in a frequency band of 0.05 to 150 Hz and has a size of several mV.

Physical and/or psychological changes of the driver may be determined through signals detected by the body temperature sensor 211, the electrocardiogram sensor 212, and the pressure sensor 213.

For example, the change of the physiological phenomenon proceeds to the stage of body temperature change after the change in the heart rate.When drowsiness, which is an example of the change in the physiological phenomenon, occurs, the driver's gripping pressure (hand grip) decreases after the change in the heart rate and body temperature. This is common. Accordingly, the biosignal detected by the first biosignal detection module 210 may be used as information for determining drowsy driving, drunk driving, and the like.

The first bio-signal detection module 210 may be composed of three electrode modules composed of a first electrode, a second electrode, and a reference electrode, and is composed of a dry type capable of measuring a bio-electrode without a separate conductive gel. Can be.

In addition, the first bio-signal detection module 210 includes a first electrode, a second electrode, and a reference electrode, and the electrode module may be installed at the 10 o'clock and 2 o'clock directions of the rim 11, but if necessary Accordingly, it may be disposed on the entire rim 11 at regular intervals.

The second biometric signal detection module 220 is installed on the upper front side of the driver to capture a face image of the driver, and includes an infrared image sensor 211.

The infrared image sensor 211 acquires a plurality of time-wise two-dimensional biometric images in a non-invasive and non-contact manner using a plurality of lasers and near-infrared image sensors that emit electromagnetic waves in the near-infrared range, and Acquires a 3D biometric image according to time when the depth of the facial skin is formed through a 3D image reconstruction algorithm for a 2D biometric image, and intensively checks the flow of blood appearing in the 3D biometric image over time. It is structured to be able to.

Through the infrared image sensor 211, it is possible to detect heat distribution and blood flow on the driver's face.

That is, by comparing the previously stored infrared image from the infrared image of the driver's face through the second biometric signal detection module 220, the driver's excited state or drinking state may be determined.

The data processing unit 300 performs a function of receiving detection data from the hands-on detection unit 100 and the biometric information detection unit 200 and shaping it into usable data.

6 is a diagram showing the configuration of a data processing unit applied to a system for providing safe driving and healthcare based on complex detection of hands-on information and biometric information according to the present invention.

Referring to FIG. 6, the data processing unit 300 includes a measurement amplification module 310, a selector module 320, and a filter module 330.

The measurement amplification module 310 receives detection data from the hands-on detection unit 100 and the biometric information detection unit 200 and amplifies the detection data.

The hands-on detection unit 100 detects a current to determine whether it is gripped, and the current detected by the grip is a relatively small current in the range of several to tens of μA. In addition, in the case of an electrocardiogram, it has a frequency band of 0.1 ~ 150Hz, and the detected body temperature signal and pressure signal are also a small signal.

The measurement amplification module 310 amplifies such a biological signal.

The selector module 320 selects the signal output from the measurement amplification module 310 and connects it to the filter module 330 at the rear stage.

That is, the selector module 320 transmits a signal output from one selected from the hands-on detection unit 100 or the biosignal detection unit 200 to the control unit 400 by a sync signal of the control unit 400 to be described later. Here, the sync signal is variable according to a predetermined period, so that the signal detected by the hands-on detection unit 100 is transmitted for a predetermined time per cycle, and the signal detected by the biosignal detection unit 200 for the rest of the time. Is transmitted.

In addition, the selector module 320 connects a corresponding electrode module and a filter.

For example, the selector module 320 connects the body temperature detection electrode module and the body temperature sensor filter based on the body temperature detection signal, and connects the ECG electrode module and the ECG sensor filter based on the ECG detection signal, and the pressure detection signal Based on this, the pressure electrode module and the pressure sensor filter are connected.

If necessary, the selector module 320 may be configured to sequentially connect the electrode modules at a predetermined cycle. In addition, in the case of the electrode module in which the abnormal biosignal has been generated, the selector module 320 may be configured to increase the connection time between the electrode module and the filter to intensively detect the biosignal in which the abnormality has occurred.

The filter module 330 filters only signals of a necessary band including a high-pass filter and a low-pass filter, and outputs biometric information about body temperature, electrocardiogram, and pressure, respectively, according to the selection of the selector module 320, and It consists of a sensor filter 331, an ECG sensor filter 332, and a pressure sensor filter 333.

At this time, in the case of the body temperature sensor filter 331, the electrocardiogram sensor filter 332, and the pressure sensor filter 333, since the small signal bands of detection values for body temperature, electrocardiogram, and pressure are different, the filter itself must be configured separately. do.

Accordingly, information detected by the hands-on detection unit 100 and the biometric information detection unit 200 is formed into available data through a separate filter by the data processing unit 300.

The control unit 400 transmits a control signal to the electronic control unit (ECU) 600 of the vehicle based on the available data standardized by the data processing unit 300.

More preferably, the control unit 400 compares the signal detected by the hands-on detection unit 100 and the biometric information detection unit 200 with the previously stored hands-on information and bio-signal information for the driver, and the detected signal is It is determined whether the stored signal is within the error range. That is, the control unit 400 compares the detected available data with the previously stored available data to determine a change of the body and a state of the driver, and outputs the determined result.

Accordingly, the controller 400 may be configured to store the driver's hands-on information and biometric information for a certain period of time, and obtain the driver's driving style and health status according to the biometric information through a predetermined algorithm.

For example, the received time, driving time, driving pattern, etc. of the driver's hands-on information and biometric information are detected and stored for a certain period, and then the average value of the stored values is calculated, and the calculated average value is greater than or equal to a predetermined value. After deleting the outlier information, it may be configured to obtain hands-on information and biometric information for the driver by using the deleted and remaining information.

The control unit 400 compares the detected available data with the previously stored available data to determine whether there is an abnormality in the body, such as body temperature, heart rate, safe driving, health care, alcohol consumption, and a Kyotong accident. Can be included.

In this case, the control unit 400 may be configured to receive information such as speed, shock detection, and position from the electronic control unit (ECU) 600 of the vehicle, and determine the driver's state according to an algorithm through the information.

1. Body temperature and heart rate

The controller 400 is configured to compare the available data detected for physical activity of body temperature and heart rate with the previously stored available data, and determine a case out of the error range as a body abnormality.

2. Safe driving

The control unit 400 is configured to be determined based on information such as hands-on information and speed and impact detection transmitted from the electronic control unit (ECU, 600) about the physical condition of safe driving.

For example, if hands-on information is not received for a certain period of time while the vehicle is running, the controller 400 may be configured to determine that the driving is careless and output a voice guide to grip the steering wheel.

3. Healthcare

The controller 400 may be configured to provide continuous health information by determining whether the driver has high/low blood pressure, hypothermia, or high fever, etc., based on previously stored available data about the driver regarding the health care situation.

4. Drunk driving

The controller 400 may be configured to determine the physical condition of the drunk driving based on available data such as an infrared image of a driver's face, heart rate, and body temperature.

Because drunk driving can cause fatal accidents not only for the driver himself but also for others, strong legal standards are restricting it. However, many drivers drive without knowing whether their drinking amount is suitable or inappropriate for drunk driving, thereby causing a car accident.

At this time, if the control unit 400 determines that the driving is drunk driving, the control unit 400 transmits a signal to forcibly stop the engine to the electronic control unit 600 or transmits a signal to limit the speed. It can be configured not to drive.

5. Traffic accident

The controller 400 may be configured to determine the physical condition of a traffic accident based on available data such as an external shock or heart rate generated while the vehicle is running.

At this time, if the control unit 400 determines that it is a traffic accident, the control unit 400 transmits a message of the content to the stored phone number based on the location information transmitted from the electronic control unit (ECU, 600). Can be configured to

The storage unit 500 stores and manages available data received from the control unit 400 and a control signal transmitted. The available data stored in the storage unit 500 is updated at a certain period according to time and is configured to be stored and managed.

If necessary, the stored available data may be configured to be transmitted to the driver's Internet storage (web DB, etc.) under the control of the controller 400.

The alarm unit 700 outputs a guide voice to the sound output device installed in the vehicle based on a control signal transmitted from the control unit 400.

The communication unit 800 performs communication with an external device through a communication network under the control of the controller 400.

At this time, the communication unit 800 may be configured to be installed in a vehicle, but after performing communication with the driver's mobile device through a physical connection with the driver's mobile device or a short-range communication means such as Zigbee or Bluetooth, if necessary, It may be configured to be connected to a pre-stored phone number or a specific address on the Internet network through the driver's mobile device.

In addition, when an emergency such as a traffic accident is required, it will be natural that communication can be made to a medical institution, an emergency rescue organization, or a predetermined specific place.

According to the present invention, by performing the basic health information of the driver in real time, it is possible to accurately cope with the occurrence of an emergency situation while driving. In addition, according to the present invention, by continuously accumulating and managing the driver's biometric information, the driver's health can be managed, and not only the driver's state can be identified, but also shared in areas such as healthcare, edutainment, and social networks. In addition, there is an advantage that can be applied to a driverless vehicle that can collect information on such drivers to build big data, and to perform safe driving based on big data.

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and it should be understood that the scope of the present invention extends to the scope substantially equal to the embodiment of the present invention. Various modifications may be made by those of ordinary skill in the technical field to which the present invention pertains within the scope not departing from the spirit of the invention.
