The driver biometric information monitoring system according to the present invention monitors the driver's biosignals for a plurality of types of measured values in each of the plurality of sensing regions as described above, thereby allowing the driver biometric information to be used regardless of conditions in various driving environments. Can be monitored efficiently.

For example, in a situation in which the seat sensing unit 150 is configured as a non-contact temperature sensor or a non-contact heart rate sensor, when the driver is driving in a thick coat, the seat sensing unit 150 has a threshold temperature of the driver for a specific time or more.

In addition to increasing the accuracy of signal monitoring, the specific sensing unit may be deactivated to cut off power consumed by the sensing unit, thereby increasing power efficiency even with a large number of sensing units.

That is, the driver biometric information monitoring system according to the present invention does not simply monitor the driver's health status according to whether the sensing result for each sensing item is within a normal range, and does not monitor the combination of the result values of the various sensing units 110 to 170. Therefore, by judging whether the driver's health condition is complex, it is possible to increase the power consumption efficiency and secure the reliability of the monitoring result by minimizing the situation of providing wrong information to the driver or controlling unnecessary vehicles according to the error of a specific sensing value. It becomes possible.

The data analyzing unit 200 may include a driver health state monitoring unit 210 and a sensing unit 100 that monitor a driver's health state based on information collected by the sensing unit 100 and the vehicle driving information acquisition unit 180. Emergency information to determine the emergency situation of the driver based on the information collected through the information collected through the, the vehicle driving information acquisition unit 180 and / or the driver health status information determined by the driver health status monitoring unit 210 The situation recognition unit 220 may be included.

Hereinafter, a method of analyzing a sensing value based on information sensed by the sensing unit 100 under various conditions will be described as an example.

In some embodiments, the driver health state monitoring unit 210 based on the driver's heart rate and blood sugar information collected through the steering wheel sensing unit 110 and / or the gear knob sensing unit 120, the cardiovascular state information of the driver. Can be monitored.

In the case where the vehicle to which the system of the present invention is applied is an automatic transmission vehicle, the gear knob sensing unit 120 operates in the parking mode P after the initial start, considering that the driver does not have much time for contacting the gear knob. It can be deactivated after sensing the driver's initial health while changing gear to (D) or reverse mode (R).

Meanwhile, in consideration of various times of contacting the gear knob according to the driver, the present invention is not limited thereto, and an activation condition of the gear knob sensing unit 120 may be variously operated. For example, through the fingerprint sensor of the steering wheel sensing unit 110 and / or the gear knob sensing unit 120, the system identifies the driver and activates the gear knob sensing unit 120 according to the driving habit of the driver. Conditions can be applied. For example, if the identified driver A has long been driving a manual transmission vehicle and has a habit of always keeping his or her hands on the gear knob even though the vehicle is an automatic transmission vehicle, the gear knob sensing unit 120 is always activated. If the identified driver B has a habit of driving with his hand on the gear knob until the end of the operation after the change of the minimum gear, the gear knob sensing unit 120 may be deactivated after the initial sensing. The driver's identification is not limited to the fingerprint recognition method as described above, and may be performed through the driver's face recognition, the driver's iris recognition, or the driver's manual input.

In some embodiments, the driver's health status monitoring unit 210 is based on the driver's face recognition information collected through the face recognition sensing unit 130, the driver's health status, whether the driver's drowsy driving, whether the driver's consciousness, etc. You can monitor the status.

The driver's health condition monitoring unit 210 learns and stores the driver's usual facial condition collected through the facial recognition sensing unit 130, and compares the stored information with the currently recognized facial condition of the driver. Know your health. For example, when the eye size currently recognized based on the learned driver's eye size is small, or when the dark circle size currently recognized based on the learned driver's dark circle size is large, the driver health monitoring unit In operation 210, the fatigue degree of the current driver may be estimated according to the difference between the stored eye size or the dark circle size and the sensed eye size or the dark circle size.

In some embodiments, the driver health monitoring unit 210 learns and stores the driver's usual face angle collected through the face recognition sensor 130, and compares the stored information with the currently recognized driver's face angle. I can understand the drowsiness of the. For example, when the currently recognized face angle based on the learned driver's face angle is different than the reference value, the driver's health state monitoring unit 210 may estimate whether the current driver's drowsy driving is performed.

Meanwhile, the driver health state monitoring unit 210 may determine the drowsiness state of the driver by combining the eye size information and the face angle information.

In some embodiments, the driver health monitoring unit 210 may detect the amount of impact delivered to the airbag, the facial body temperature, the bleeding estimated amount detected by the airbag, and the headrest sensing unit when the airbag is collected through the airbag sensing unit 140. The health of the driver after an accident through the amount of impact applied to the driver's head in a situation such as an accident collected through the 160, the amount of impact applied to the body of the driver in the event of an accident collected through the seat belt sensing unit 170, etc. The state can be predicted. Alternatively, the driver health monitoring unit 210 may estimate the driver's unconscious state after the accident according to whether the airbag collected through the airbag sensing unit 140 and the driver's face contact continue.

The driver's health state monitoring unit 210 may monitor the driver's current health state based on body temperature information and heart rate information sensed by the seat sensing unit 150. In some embodiments, the driver health monitoring unit 210 determines whether the driver is seated based on the pressure information sensed by the seat sensing unit 150, and other sensing units other than the seat sensing unit 150 according to the seating state. 110 to 140 and 160 to 170 may be determined. Through this, the sensing unit 100 may operate in a situation in which no sensing is required, thereby preventing unnecessary power consumption.

The emergency situation recognition unit 220 may monitor the driver's health state by combining the information collected as described above through the sensing unit 100 and the vehicle driving information collected through the vehicle driving information acquisition unit 180. For example, the vehicle driving information acquisition unit 180 determines that the vehicle is currently running and the input value is input to the steering wheel sensing unit 110 and the gear knob sensing unit 120 in a situation not in the autonomous driving mode. If not, the emergency situation recognition unit 220 may determine that the current driver is unconscious even if the driver's health condition monitoring unit 210 estimates that the driver's health is normal based on the sensing value.

The operation unit 400 may include a speaker 410, a display 420, an electronic control unit (ECU) 430, a communication module 440, and a drone control module 450.

In some embodiments, the speaker 410, the display 420 and the ECU 430 may be hardware of the vehicle itself, and the communication module 440 and the drone control module 450 may be separately provided in the vehicle. It may be hardware on the system, but is not limited thereto.

When the driver's health condition monitoring unit 210 determines that the driver's health condition is abnormal, the driver's health condition monitoring unit 210 may present the driver to the driver through the speaker 410 and / or the display 420 of the operation unit 400. Can warn you of your health.

The controller 300 warns the driver of the current situation through the speaker 410 and / or the display 420 of the operation unit 400 based on the information transmitted through the emergency situation recognition unit 220, or the ECU. 430, the operation of the communication module 440 and the drone control module 450 may be controlled.

2 is a flowchart illustrating a driver biometric information monitoring and a vehicle and system control method according to an embodiment of the present invention.

Referring to FIG. 2, when the driver starts the vehicle and moves the gear knob to change the gear from the parking mode (P) to the drive mode (D) or the reverse mode (R) (S210), the driver health monitoring unit In operation 210, the driver health state is initially analyzed based on the information collected through the gear knob sensing unit 120 (S220).

If it is determined that the driver's health state is capable of driving, the system may acquire and monitor biometric information of the driver through various sensing units 110 to 170 of the sensing unit 100 (S250). If it is determined that the driver's health state is impossible to drive, the controller 300 may move the gear knob to the parking mode P through the control of the ECU 430.

During the driver health state monitoring (S250), the emergency situation recognition unit 220 may determine whether an emergency situation, such as drowsy driving of the driver or whether the driver is unconscious, occurs as described above with reference to FIG. 1 based on various sensing information. There is (S260).

When it is determined that an emergency situation has occurred, the emergency situation recognition unit 220 first determines whether the driver is unconscious while driving based on the information from the vehicle driving information acquisition unit 180 (S270), or whether the driver is unconscious. S280 may be determined.

When the driver is unconscious while driving, the controller 300 may control to safely emergency stop the vehicle through the control of the ECU 430 (S275).

In the case of the stationary driver's consciousness unknown situation, the data analysis unit 200 determines that the driver's consciousness is unknown due to an accident, and in this case, the control unit 300 transmits position information to a rescue team through a communication module and calls an ambulance. It may be (S282). In addition, before the ambulance arrives, paramedics first call and control the drone so as to understand the driver's current state, and control the window of the vehicle so that the drone can clearly photograph the driver inside the vehicle. It can send to a circle etc. (S284).

In some embodiments, the drone may be provided at the trunk of a vehicle or the like, or may be called at a drone station equipped with an infrastructure for emergency dispatch on the road.

In some embodiments, the control unit 300 may control the vehicle window according to the positional relationship between the drone and the vehicle in order to prepare a case where the interior of the vehicle cannot be easily seen from the outside such as tinting of the vehicle window. For example, when the drone is flying in the driver's seat of the vehicle, the driver's window may be opened, but the window of the non-shooting window or the window where the shooting is finished may be closed to prevent a winter temperature loss.

3 is a flowchart illustrating a driver biometric information monitoring and vehicle and system control method according to an embodiment of the present invention.

In FIG. 3, a method of determining whether the driver has become unconscious while driving while a vehicle is determined to be in an emergency situation will be described as an example.

Referring to FIG. 3, the data analyzer 200 may determine whether the autonomous driving mode of the vehicle is in operation (S310). Step S310 is performed only when the autonomous driving function is mounted on the vehicle, and may be omitted in a vehicle without the autonomous driving function.

When the autonomous driving mode is not in operation, the data analyzer 200 determines whether a driver's input is present in the steering wheel (S320).

If it is determined that the driver's input does not exist in the steering wheel, the controller 300 may request the driver to grip the steering wheel through the speaker 410 and / or the display 420 (S330).

If the driver does not accept the request of step S330, the data analysis unit 200 determines that the driver is unconscious while driving (S350), and in this case, emergency stop of the vehicle through ECU control as described with reference to FIG. Can be.

4 is a flowchart illustrating a driver biometric information monitoring and vehicle and system control method according to an embodiment of the present invention.

In FIG. 4, a method of determining whether a driver becomes unconscious while stopping is assumed on the assumption that the driver is in an emergency situation in a stopped state of the vehicle.

Referring to FIG. 4, the data analyzing unit 200 determines whether the vehicle stopping direction of the vehicle is stopped by i) an external force based on the information from the vehicle driving information acquisition unit 180, ii) the controller 300 It is possible to determine whether the vehicle is stopped by controlling the ECU 430, or iii) whether the driver's will, that is, the vehicle stops due to the brake pedal development (S410).

When it is determined that the vehicle is stopped by an external force, the data analyzer 200 determines whether the airbag of the vehicle is deployed (S420). If the airbag is deployed, it may be determined as a stop due to an accident, and it may be determined whether there is a sensing value from the sensors of the airbag sensing unit 140 (S422). When the sensing value of the airbag sensing unit 140 exists, it is determined from the airbag sensing unit 140 whether the sensing value continuously exists in excess of the reference time (S424), and when the reference time is exceeded, the driver stops due to an accident or the like. If it is determined that the state is unconscious (S434), otherwise, if the sensing value disappears before the reference time is exceeded, it may be determined that the driver's consciousness exists (S426).

If there is no sensing value of the airbag sensing unit 140 in step S422, the driver may request to hold the steering wheel through a speaker (S430).

When it is determined in step S410 that the stopping process is stopped by the controller 300 controlling the ECU 430, the driver may request that the driver grip the steering wheel through a speaker or the like (S430).

The data analysis unit 200 determines whether the driver accepts the request according to the step S430 (S432), and if the driver does not comply with the request, determines that the driver is unconscious in the stopped state (S434). If the wheel is gripped, it may be determined that the driver's consciousness exists (S442).

When it is determined in step S410 that the stop is the stop according to the driver's will, that is, the brake pedal development, the face recognition sensing unit 130 performs the face recognition of the driver (S440), when the face recognition is normal If it is determined that there is a consciousness (S442), and facial recognition is not normal, the driver may request to grip the steering wheel through the speaker (S430).

The steering wheel sensor 524 may have a configuration corresponding to the steering wheel sensor unit 110 described above with reference to FIGS. 1 to 4, and description thereof will be omitted.

As illustrated in FIG. 5, the steering wheel sensor 524 may be disposed to avoid a portion where the hot coil 522 passes from the driver side of the rim 520. In other words, the steering wheel sensor 524 may be disposed between the two hot wire portions 522a and 522b so as not to overlap the two hot wire portions 522a and 522b passing on the driver side of the rim 520.
