Description

Vehicle operation control system based on driver status

The present invention relates to a vehicle operation control system based on a driver's state, and more particularly, to a system for controlling vehicle operation based on a driver's state calculated using sensors installed in the vehicle.

Traffic accidents caused by drunk driving or a serious illness of the driver lead to major accidents, so the seriousness of accidents and damage caused by drunk driving or disease is continuously promoted, but the number of driving accidents is not decreasing.

Despite the frequent occurrence of drunk driving or disease-related accidents in Korea, reducing drunk driving only with police crackdowns is only a short-term measure. Moreover, these deterrence measures are ineffective for habitual and chronic drunk drivers or patients with serious diseases.

Accordingly, there has been proposed a method of restricting the starting of a vehicle when various biosensors are installed in a vehicle and a serious disease is detected by detecting an alcohol component by measuring the driver's respiration or by measuring blood pressure or pulse.

However, in a situation where the complexity of hardware has increased due to the addition of various buttons, heating wires, and sensors to the vehicle to implement a smart car or autonomous vehicle, the location where the driver touches so that the driver's biometric information can be easily collected When sensors are added at a location close to the driver or the driver, the possibility of errors in the vehicle control system increases and the driver's convenience decreases.

Referring to FIG. 1 , a vehicle operation control system 10 according to an embodiment of the present invention includes an electronic device 20 used by a driver or a company managing a driver using a network through a communication unit 600 and Communication can be connected. Through this, the vehicle driving control system 10 may notify the driver or a management company of a message indicating that driving is impossible because the driver is drunk or ill. Networks may include wireless networks and wired networks. For example, the network may be a short-range communication network (eg, Bluetooth, WiFi direct, or infrared data association (IrDA)) or a telecommunications network (eg, a cellular network, the Internet, or a computer network (eg, LAN or WAN)). have.

In one embodiment, the electronic device 20 is, for example, an integrated management server (server), a smartphone (smartphone), a tablet PC (tablet personal computer), a mobile phone (mobile phone), a video phone, an e-book reader ( e-book reader), desktop PC (desktop PC), laptop PC (laptop PC), netbook computer, workstation, PDA (personal digital assistant), PMP (portable multimedia player), MP3 player, It may include at least one of a mobile medical device, a camera, and a wearable device.

In an embodiment, the vehicle operation control system 10 may detect the driver's condition to control the vehicle's starting, and for this purpose, the skin humidity sensor 200 , the infrared sensor 300 , the starting motor 400 , and the display It may include a unit 500 and a communication unit 600 . For example, the vehicle operation control system 10 may detect the driver's drinking or disease state by using the skin humidity sensor 200 and the infrared sensor 300, and when the driver is intoxicated or ill, the vehicle You can set the ignition to a locked state.

In an embodiment, the controller 100 may calculate the driver state t based on detection of at least one of the skin humidity sensor 200 and the infrared sensor 300 . Specific details on this will be described later with reference to FIG. 2 .

In an embodiment, the controller 100 may control overall operations of each component for detecting the driver's state. To this end, the controller 100 may perform data communication through each of the components and an internal network. Here, the internal network may be a CAN communication method or an RS485 communication method in which the multi-master function is supported.

In an embodiment, the control unit 100 may be connected to the skin humidity sensor 200 and the infrared sensor 300 through a network, and each sensor may detect the motion itself detected by sensing data from the driver. Also, the controller 100 may receive sensor data obtained from the skin humidity sensor 200 and the infrared sensor 300 . For example, the controller 100 may continuously receive a sensor data stream from the skin humidity sensor 200 and the infrared sensor 300 . Here, the sensor data stream may be a data set according to the passage of time of sensor data received from the skin humidity sensor 200 and the infrared sensor 300 . For example, the sensor data stream may include the driver's skin humidity and body temperature, but is not limited thereto, and may further include various types of driver-related sensor data.

In an embodiment, the skin humidity sensor 200 is installed in a vehicle (eg, a steering wheel, a door handle) and may detect the driver's skin humidity (or the amount of moisture in the skin). By flowing an electric current through the user's skin to measure the impedance of the user's skin, it serves to detect the level of moisture in the user's skin. The skin humidity sensor 200 is a sensor that effectively acquires in-body diagnostic information by measuring bio-impedance (resistance) of tissues in the body, and in particular, measures the amount of moisture that can determine the user's skin condition. By bringing the reference electrode and the measuring electrode into contact with the skin surface of the body part to be measured, and applying a microcurrent thereto to measure the voltage between the two electrodes, the distribution of impedance inside the body or the change of impedance according to time and frequency By reconstructing the body information, it is possible to diagnose the body information.

2 is a flowchart illustrating a vehicle operation control method according to an embodiment of the present invention. The operations of FIG. 2 may be performed by the controller 100 of FIG. 1 .

Referring to FIG. 2 , in an embodiment, the control unit 100 may detect a sensing operation of at least one of the skin humidity sensor 200 and the infrared sensor 300 in operation 21 . For example, as the driver approaches the vehicle, the infrared sensor 300 installed on the vehicle body or the skin humidity sensor 200 installed on the handle may detect the user's skin humidity or temperature. Here, the sensing operation is not limited to the case where the skin humidity or temperature above a specific value is sensed, but means detecting the user's skin humidity or temperature. That is, the controller 100 may detect the sensing operation whenever at least one of the skin humidity 200 and the infrared sensor 300 detects the user's skin humidity or temperature.

In an embodiment, the controller 100 may calculate the driver's state according to Equation 1 in operation 22 . In the past, there is simply a preset threshold, and when the value sensed by the sensor exceeds the threshold, it is determined that the user is drinking. However, since the present invention determines the user's state according to the finite linear game theory to be described below, even when the sensors acquire any sensing value, the driver's state can be calculated in response to the sensing operation.

Specifically, the finite linear game theory is a theory applied in a situation where a physical system having a finite number of states must be considered. These states can be changed by application of a process that yields a finite number of outcomes at a time. For example, an incandescent light bulb can be turned on or off, and a switch can change the incandescent light bulb from an on state to an off state.

For example, digital systems from Computer Science can be applied to finite linear game theory. More commonly, many computer games are in the form of puzzles, in which there must be a device that must be controlled with several switches to produce the desired result. In such a situation, finiteness is suitable for analysis using arithmetic modules, and often a system of linear equations over Z (p dimensions, p is a natural number) plays a role. A problem involving this type of situation is called a finite linear game.

For example, two light bulbs are connected in a row, each of which is either off, light blue, or dark blue. Below each light bulb are two switches A and B, each of which can change the light's state to off, dark blue, or light blue.

According to the above finite linear game theory, substituting the case of determining the driver's state in the system 10 of the present invention, the skin humidity sensor 200 can be viewed as a switch a, and the infrared sensor can be viewed as a switch b. have. And, xi denotes the number of times the i-th switch was pressed, x ₁ denotes the presence or absence of drinking, and x ₂ denotes the presence or absence of disease. Assume all light bulbs are off initially, switch A and switch B change the driver's state

In the above situation assumed according to the finite linear game theory, the first embodiment in which the skin humidity sensor 200 detects only disease and the infrared sensor 300 detects only drinking will be described.

Here, there are a total of two switches, A and B, and it is assumed that they are two-dimensional.

For example, the controller 100 may calculate the driver's state t according to Equation 1 below based on detection of at least one of the skin humidity sensor 200 and the infrared sensor 300 . Here, the control unit 100 calculates the driver's state by using the finite linear game theory, rather than calculating only by Equation (1).

[Equation 1]

Here, a is a skin humidity sensor, b is an infrared sensor, X ₁ is the driver's drinking state, and X ₂ is the driver's disease state.

That is, as described above, according to the finite linear game theory, the skin humidity sensor 200 can be viewed as a switch A, and the infrared sensor 300 can be viewed as a switch B. FIG. For convenience of description, it will be described as a switch A and a switch B.

For example, the controller 100 may set a and b to the following Equation 2 so that a reflects the skin humidity sensing function of the skin humidity sensor 200 and b reflects the temperature sensing function of the infrared sensor.

[Equation 2]

Here, in the a matrix and the b matrix, the number 0 in the first row indicates that the alcohol detection function is OFF, the number 1 in the first row indicates that the alcohol detection function is ON, and the number 0 in the second row indicates that the disease detection function is OFF. and number 1 in the second row indicates that the disease detection function is ON.

That is, to elaborate on it, the switch A corresponds to the matrix a, and the switch B corresponds to the matrix b. When the switch A is pressed, the switch A may change the driver's state from the normal state to the disease state, and when the switch B is pressed, the switch B may change the driver's state from the normal state to the drinking state.

For example, the controller 100 may set t to any one of Equation 3, Equation 4 or Equation 5 below to reflect the operation of changing the driver's state in response to at least one of a and b. have.

[Equation 3]

[Equation 4]

[Equation 5]

Here, t can be regarded as a vector of the final target state, and when t is Equation 3 or 4, only one of switch A or switch B is reacted, and when t is Equation 5, This is the case in response to both switch A and switch B.

After t, a, and b are assumed by reflecting the finite linear game theory as described above, scalars x ₁ and x ₂ satisfying Equation 1 in two dimensions can be obtained as follows.

First, an addition coefficient matrix [ab ㅣ t] can be considered from Equation 1, and when t is three cases in two dimensions, the row can be reduced to a reduced event trapezoid, and thus x ₁ and x ₂ can be obtained can

For example, when t is set to Equation 3, the controller 100 may determine the driver's state as drinking based on Equation 1 and the finite linear game theory. For example, as in Equation 1 below, if the addition coefficient matrix of Equation 1 (left side of Equation 1) is arranged according to the reduced exercise trapezoid rule, the first column in the first row becomes 1 and the second column becomes 1 in the second row. It can be reduced as much as possible and converted into the reduced exercise trapezoid of Equation 1 (the matrix on the right of Equation 1), and _{only X 1} has a value of 1, so switch A is pressed, and it is determined that the factor where switch A is pressed is drinking. can be considered as drinking.

[Equation 1]

For example, when t is set to Equation 4, the controller 100 may determine the driver's condition as a disease based on Equation 1 and the finite linear game theory. For example, as in Equation 2 below, if the addition coefficient matrix of Equation 2 (left side of Equation 2) is arranged according to the reduced exercise trapezoid rule, the first column in the first row becomes 1 and the second column becomes 1 in the second row. It can be shortened as much as possible and transformed into the reduced exercise trapezoid of Equation 2 (the matrix on the right of Equation 2), and _{only X 2} has a value of 1, so switch B is pressed, and the driver state as it is determined that the factor where switch B is pressed is a disease can be considered a disease.

[Equation 2]

For example, when t is set to Equation 5, the controller 100 may determine the driver's state as drinking and disease based on Equation 1 and the finite linear game theory. For example, as shown in Equation 3 below, if the addition coefficient matrix of Equation 3 (left side of Equation 3) is arranged according to the reduced exercise trapezoid rule, the first column in the first row becomes 1 and the second column becomes 1 in the second row. It can be reduced as much as possible and transformed into the reduced event trapezoid of Equation 3 (the matrix on the right of Equation 3), and since X ₁ and X ₂ have a value of 1, both switch A and switch B are pressed, and the factors that are both depressed are alcohol and disease. According to the judgment, the driver's condition may be judged to be alcohol or disease.

[Equation 3]

Next, the second embodiment in which the skin humidity sensor 200 detects only disease and the infrared sensor 300 detects both drinking and disease will be described. Here, there are a total of two switches, A and B, and it is assumed that they are two-dimensional.

For example, the controller 100 may calculate the driver's state t according to Equation 1 below based on detection of at least one of the skin humidity sensor 200 and the infrared sensor 300 . Here, the control unit 100 calculates the driver's state by using the finite linear game theory, rather than calculating only by Equation (1).

[Equation 1]

Here, a is a skin humidity sensor, b is an infrared sensor, X ₁ is the driver's drinking state, and X ₂ is the driver's disease state. That is, as described above, according to the finite linear game theory, the skin humidity sensor 200 can be viewed as a switch A, and the infrared sensor 300 can be viewed as a switch B. FIG. For convenience of description, it will be described as a switch A and a switch B.

For example, the controller 100 may set a and b to the following Equation 6 so that a reflects the skin humidity sensing function of the skin humidity sensor 200 and b reflects the temperature sensing function of the infrared sensor.

[Equation 6]

Here, in the a matrix and the b matrix, the number 0 in the first row indicates that the alcohol detection function is OFF, the number 1 in the first row indicates that the alcohol detection function is ON, and the number 0 in the second row indicates that the disease detection function is OFF. and number 1 in the second row may indicate that the disease detection function is ON.

That is, to elaborate on it, the switch A corresponds to the matrix a, and the switch B corresponds to the matrix b. When the switch A is pressed, the switch A may change the driver's state from the normal state to the sick state, and when the switch B is pressed, the switch B may change the driver's state from the normal state to the drinking and ill state.

For example, the control unit 100 may set t as Equation 3, Equation 5, or Equation 7 below to reflect the operation of changing the driver's state in response to at least one of a and b. have.

[Equation 3]

[Equation 5]

[Equation 7]

Here, t can be regarded as a vector of the final target state, and when t is Equation 3 or 5, only one of the switch A or switch B is reacted, and when t is Equation 7, This is the case in response to both switch A and switch B.

After t, a, and b are assumed by reflecting the finite linear game theory as described above, scalars x ₁ and x ₂ satisfying Equation 1 in two dimensions can be obtained as follows.

First, an addition coefficient matrix [ab ㅣ t] can be considered from Equation 1, and when t is three cases in two dimensions, the row can be reduced to a reduced event trapezoid, and thus x ₁ and x ₂ can be obtained can

For example, when t is set to Equation 3, the controller 100 may determine the driver's state as drinking based on Equation 1 and the finite linear game theory. For example, as shown in Equation 4 below, if the addition coefficient matrix of Equation 4 (left side of Equation 4) is arranged according to the reduced exercise trapezoid rule, the first column in the first row becomes 1 and the second column becomes 1 in the second row. It can be reduced as much as possible and converted into the reduced exercise trapezoid of Equation 4 (the matrix on the right of Equation 4), and _{only X 1} has a value of 1, so switch A is pressed. can be considered as drinking.

[Equation 4]

For example, when t is set to Equation 5, the controller 100 may determine the driver's condition as a disease based on Equation 1 and the finite linear game theory. For example, as in Equation 5 below, if the addition coefficient matrix of Equation 5 (left side of Equation 5) is arranged according to the reduced exercise trapezoid rule, the first column in the first row becomes 1 and the second column becomes 1 in the second row. It can be reduced as much as possible and transformed into the reduced exercise trapezoid of Equation 5 (the matrix on the right of Equation 5), and _{only X 2} has a value of 1, so switch B is pressed, and it is determined that the factor where switch B is pressed is a disease. can be considered a disease.

[Equation 5]

For example, when t is set to Equation 7, the controller 100 may determine the driver's state as drinking and disease based on Equation 1 and the finite linear game theory. For example, as shown in Equation 6 below, if the addition coefficient matrix of Equation 6 (left side of Equation 6) is arranged according to the reduced exercise trapezoid rule, the first column in the first row becomes 1 and the second column becomes 1 in the second row. It can be shortened as much as possible and transformed into the reduced event trapezoid of Equation 6 (the matrix on the right of Equation 6), and since X ₁ and X ₂ have a value of 1, both switch A and switch B are pressed, and the factors that are both depressed are alcohol and disease. According to the judgment, the driver's condition may be judged to be alcohol or disease.

[Equation 6]

In an embodiment, the controller 100 may control starting of the vehicle according to the calculated driver state in operation 23 . For example, when it is determined that the driver's condition corresponds to drinking, illness, or both, the control unit 100 may lock the ignition regardless of whether the driver is in the vehicle or starting the vehicle, and may stop the driver's operation. can stop In addition, the control unit 100 may display a warning message about drinking or disease to the driver through the display unit 500 , and may display the driver's drinking or disease warning message on the electronic device 20 used by the company through the communication unit 600 . It is possible to transmit the state in which the vehicle's ignition is locked by means of a message.
