The control unit 40 may primarily determine the driver's status based on the driver's status information detected by the sensor unit 21.

Additionally, if the control unit 40 determines that the driver's condition is abnormal as a result of the first determination, the control unit 40 may finally determine the driver's condition based on the information captured by the camera 30.

Since a temporary error may occur in the detection result by the sensor unit 21 due to noise, etc. generated from the vehicle 10, the control unit 40 determines 1 according to the detection result by the sensor unit 21. If the car is determined to be abnormal as a result of the car judgment, the driver's condition can be determined more accurately by secondarily determining the driver's condition based on the information captured by the camera 30.

Electrical components such as the control unit 40, the sensor and camera 30, the display unit 50 and the lamp 60, which will be described later, can communicate with each other through a communication network within the vehicle 10. For example, electronic components transmit data through Ethernet, MOST (Media Oriented Systems Transport), Flexray, CAN (Controller Area Network), LIN (Local Interconnect Network), etc. You can give and receive.

Figure 3 is a diagram showing a steering wheel including a sensor according to one embodiment.

The sensor unit 21 is provided on the steering wheel 20 and can detect information about the driver's condition while the driver holds the steering wheel 20 for steering.

This sensor unit 21 may be provided entirely on the steering wheel 20, or may be provided only on a portion of the steering wheel 20, as shown in FIG. 3. It can be placed in various locations to detect driver's status information.

The sensor unit 21 can detect at least one of the driver's heart rate or blood pressure while the driver is holding the steering wheel 20.

Heart rate and blood pressure are just examples of information about the driver's condition, and various other information about the driver's condition can be detected. For example, it can further detect information about the driver's stress level, oxygen saturation, etc.

The control unit 40 can determine whether the driver's condition is normal by comparing the detection information of the sensor unit 21 with information corresponding to the heart rate or blood pressure in a normal state previously stored in the memory 42.

As a result of the comparison, if the detected heart rate or blood pressure is higher or lower than a certain value compared to the normal value, the control unit 40 may determine that the driver's condition is abnormal.

In addition, as described above, the sensor unit 21 can further detect the driver's stress level, oxygen saturation, etc., and in this case, the control unit 40 compares the detected value with the value corresponding to the normal state to determine the driver's condition. You can judge whether it is normal or not.

Figure 4 is a diagram illustrating photographing a driver according to one embodiment.

As described above, the camera 30 may be placed in various positions to capture the face and body of the driver seated in the driver's seat facing the steering wheel 20. For example, the camera 30 may be provided to face the driver's seat from the front inside the vehicle 10 to enable acquisition of images of the area where the driver's face is located. Additionally, it may be provided to face the driver's seat from the upper front inside the vehicle 10 to enable acquisition of images of the driver's face and body.

FIG. 4 shows a case where the camera 30 is provided near the rear-view mirror and faces the driver.

Because it is difficult to accurately determine the driver's condition only with the detection result of the sensor unit 21 due to noise generated in the vehicle 10, etc., if the driver's condition is determined to be abnormal as a result of the detection by the sensor unit 21, the camera (30) ) The driver's condition can be secondarily judged based on the results taken by .

Specifically, the control unit 40 may compare information captured by the camera 30 with information corresponding to the driver's normal state previously stored in the memory 42 and determine the driver's state according to the comparison result.

The control unit 40 may learn the driver's daily appearance captured by the camera 30 and store information corresponding to the driver's normal state in the memory 42.

The control unit 40 can determine the driver's condition by comparing this stored information with information captured by the camera 30.

Information captured by the camera 30 may include at least one of information about the driver's face and information about the driver's gestures.

For example, the control unit 40 may determine the driver's condition by comparing the driver's facial shape or facial muscle changes in the driver's facial image captured by the camera 30 with the driver's usual facial shape or muscle changes. there is.

When a driver is in an emergency situation, he or she may show facial shape or muscle changes that are different from usual, so the control unit 40 may determine that the driver's condition is abnormal if such differences appear as a result of comparison.

In addition, when comparing the driver's gestures with his usual gestures, if the driver is in a sudden emergency situation, he may make gestures that would not appear in a normal driving environment, such as lowering his head or making loud noises, so the control unit 40 determines the following as a result of the comparison. If a difference appears, the driver's condition can be judged to be abnormal.

By performing a secondary determination based on the shooting information from the camera 30 after the primary determination by the sensor unit 21, the driver's condition can be determined more accurately.

FIG. 5 is a diagram illustrating classification into a plurality of stages according to the driver's state according to an embodiment.

The control unit 40 may determine the driver's state according to the above-described process and divide the driver's state into a plurality of stages according to the final determination result.

For example, as shown in FIG. 5, if the driver shows the same state as usual, the driver's state can be determined to be 'normal' and classified as level 0.

Additionally, if it is determined that the driver is in a mild state such as fatigue, the control unit 40 can classify it into level 1.

If it is determined that the driver is in a serious condition, the control unit 40 can divide it into two stages, and if it is determined that the driver is in a serious condition requiring urgent action due to loss of consciousness, etc., the control unit 40 can divide it into three stages. can be distinguished.

In this way, the driver's state can be divided into a plurality of stages, and the control unit 40 can take different responses according to the divided stages.

FIG. 6 is a diagram illustrating a control block diagram of a vehicle according to an embodiment, and FIG. 7 is a diagram illustrating a display of a driver's state according to an embodiment.

The vehicle 10 according to one embodiment may further include a display unit 50 and a lamp 60.

The lamp 60 is provided on the outside of the vehicle 10 and can blink, and may include an emergency light provided on the outside of the vehicle 10.

If the driver's condition is determined to be mild as a result of the above-mentioned determination of the driver's condition, the control unit 40 may classify it into one stage and control the display unit 50 to display information about the driver's condition.

Specifically, it can be controlled to display the detection results by the sensor unit 21 and display a rest recommendation message such as “Take a break.”

If the driver's condition is mild, such as fatigue, it can be resolved by displaying a message to draw the driver's attention and encourage him to rest. Therefore, in such a mild condition, the control unit 40 displays information about the driver's condition. The display unit 50 can be controlled to do so.

Below, cases where the driver's condition is judged to be severe or critical will be explained.

FIG. 8 is a diagram illustrating a flashing lamp of a vehicle according to one embodiment.

The control unit 40 determines the driver's condition and, if it is determined that the driver's condition is in a serious or critical condition, can perform several levels of response measures because it is an urgent situation requiring emergency measures.

First, the control unit 40 may control the driving unit (not shown) to change the driving mode of the vehicle 10 to autonomous driving mode (Autonomous Mode).

If the driver is in a serious or emergency condition, he or she cannot drive normally and there is a risk of a major accident occurring, so it is necessary to switch the driving of the vehicle 10 to autonomous driving mode. Accordingly, the control unit 40 can switch all driving of the vehicle 10 to the autonomous driving mode, thereby freeing the driver from driving.

Additionally, the control unit 40 can control the lamp 60 provided on the outside of the vehicle 10 to flash to notify the outside of an emergency situation.

For example, the emergency lights can be continuously flashed so that the external vehicle 10 can recognize that an emergency situation has occurred in the vehicle 10.

In addition, since it is necessary to notify the external server 100, such as the center, of an emergency situation and take action, this is described below.

FIG. 9 is a diagram illustrating a control block diagram of a vehicle according to an embodiment, and FIG. 10 is a diagram illustrating displaying route guidance information to a nearby cooperative organization according to an embodiment.

The vehicle 10 according to one embodiment may further include a communication unit 70 that communicates with the external server 100.

If the driver's condition is determined to be at a serious or critical level, the communication unit 70 may transmit information about the driver's condition to the external server 100.

The communication unit 70 may receive information about nearby cooperative organizations and route information to the cooperative organizations from the external server 100.

The control unit 40 may control the AVN 52 to display the route information received by the communication unit 70.

The vehicle 10 switched to autonomous driving mode according to this route information can perform autonomous driving with the cooperative organization as its destination and transport the driver to the cooperative organization.

Accordingly, appropriate measures can be taken to drivers in emergency situations and emergency treatment can be performed within the golden time.

11 to 13 are flowcharts showing a vehicle control method according to an embodiment.

Information about the driver's health status can be detected through the sensor unit 21 provided in the steering (1001), and photographing information can be collected by photographing the driver with the camera 30 (1003).

The sensor unit 21 can detect at least one of the driver's heart rate or blood pressure while the driver is holding the steering wheel 20, and can further detect various information about the driver's condition. For example, it can further detect information about the driver's stress level, oxygen saturation, etc.

Additionally, the information captured by the camera 30 may include at least one of information about the driver's face and information about the driver's gestures.

Afterwards, the driver's health status can be primarily determined based on the driver's health status information detected by the sensor (1005).

As a result of the determination, if it is determined that the driver's health condition is abnormal (No in 1007), the driver's health condition can be finally determined based on the information captured by the camera 30.

Since a temporary error may occur in the detection result by the sensor unit 21 due to noise generated from the vehicle 10, etc., the first judgment result according to the detection result by the sensor unit 21 is abnormal. If it is determined that the driver's condition is secondarily determined based on the information captured by the camera 30, the driver's condition can be determined more accurately.

The control unit 40 may determine the driver's state and divide the driver's state into a plurality of stages according to the final determination result (1101).

If the driver shows the same condition as usual, the driver's condition can be judged as 'normal' and classified as level 0. Additionally, if it is determined that the driver is in a mild state such as fatigue, the control unit 40 can classify it into level 1. If it is determined that the driver is in a serious condition, the control unit 40 can divide it into two stages, and if it is determined that the driver is in a serious condition requiring urgent action due to loss of consciousness, etc., the control unit 40 can divide it into three stages. can be distinguished.

As a result of the determination, if it is determined that the driver's condition is in a normal state (example in 1103), the existing control can be maintained (1105).

As a result of the determination, if the driver's condition is determined to be at a mild level (example in 1107), information about the driver's condition can be displayed (1109).

Specifically, it can be controlled to display the detection results by the sensor unit 21 and display a rest recommendation message such as “Take a break.”

If the driver's condition is mild, such as fatigue, it can be resolved by displaying a message to draw the driver's attention and encourage him to rest. Therefore, in such a mild condition, the control unit 40 displays information about the driver's condition. The display unit 50 can be controlled to do so.

As a result of the determination, if the driver's condition is determined to be at a serious or critical level (example in 1111), the driving mode of the vehicle 10 may be controlled to be switched to the autonomous driving mode (1201).

If the driver is in a serious or emergency condition, he or she cannot drive normally and there is a risk of a major accident occurring, so it is necessary to switch the driving of the vehicle 10 to autonomous driving mode. Accordingly, the control unit 40 can switch all driving of the vehicle 10 to the autonomous driving mode, thereby freeing the driver from driving.

Additionally, the lamp 60 provided on the outside of the vehicle 10 can be controlled to blink to notify the outside of an emergency situation (1203). For example, the emergency lights can be continuously flashed so that the external vehicle 10 can recognize that an emergency situation has occurred in the vehicle 10.

Afterwards, information about the driver's health status can be transmitted to the external server 100 (1205), and information about nearby cooperative organizations and route information to the cooperative organizations can be received from the external server 100 (1207).

Afterwards, the AVN 52 can be controlled to display the received route information to the cooperating institution (1209), and the vehicle 10 switched to autonomous driving mode according to this route information can drive autonomously with the cooperating institution as its destination. It can be carried out and the driver can be transferred to a partner organization.

According to the disclosed invention, it is possible to prevent traffic accidents by first detecting sudden changes in the driver's health status by checking the driver's health status in real time using sensors and cameras, and immediately detecting sudden changes in the driver's health status when an unexpected health condition occurs while driving. Risk to life can be reduced by receiving emergency treatment immediately upon arrival by notifying partner organizations (hospitals/police) through linkage with the center. In addition, since errors may occur in the sensor detection results due to vehicle noise, etc., the driver's condition can be determined more accurately by secondarily determining the driver's condition using a camera.
