Safe driving of the vehicle is an important part of the safety of the driver and the passenger, as well as to prevent personal injuries and property losses in the other lane and surroundings.

In addition, the number of traffic accidents caused by the aging population is increasing in proportion to the increase of elderly drivers. This is because the possibility of traffic accidents is high because of elderly driver's immature driving or slow reaction speed. Therefore, it is necessary to develop a safe driving assistance system for elderly people.

In particular, the probability of suffering from chronic diseases is extremely high in the elderly, and when a person with a chronic illness experiences an abnormal condition during driving, it causes a very dangerous situation. In recent years, the word Road Rage has become so widespread that it has failed to overcome anger and excitement while driving, resulting in an abrupt drive, resulting in a sudden increase in traffic accidents.

Recently, smart cars and various advanced equipments related to them are being introduced as future cars. These devices and technologies are included in ADAS to enhance safety and convenience. In other words, it is a technology that puts eyes and ears on a car, so that an intelligent car helps the driver to drive safely and conveniently. Therefore, it is expected that the advanced operation resource system will be very helpful for the safe driving of the elderly.

1 is an internal view of a vehicle for illustrating a configuration of a safe driving assist system according to the present invention.

As shown, the safe driving assistance system of the present invention utilizes configurations that are already in use in a typical automotive environment. In other words, a navigation system is provided in the vehicle to assist the user in locating the vehicle and guiding the vehicle. The vehicle is equipped with a black box for mounting a camera and monitoring and recording the collision with the outside and various other peripheral dangerous situations. In the vehicle, various kinds of biosensors for detecting the physical changes of the driver are installed and utilized. As shown in the drawing, the present invention uses a smart phone which is a mobile communication terminal of a driver. The mobile communication terminal can be used as a substitute for various terminals such as a tablet PC and a notebook computer.

2 is an external view of a vehicle for displaying a warning message or the like by applying the safe driving assist system according to the present invention.

The safe driving assist system of the present invention is configured so that display control can be performed according to safe driving to the outside of the vehicle. For example, a rear display is provided on the rear glass of the vehicle, and display control is performed so as to recognize a dangerous situation of the vehicle ahead of the vehicle. It is also possible to output a warning message to the driver and the outside using an in-vehicle sound output device (speaker) and an emergency light.

FIG. 3 shows a general configuration diagram of a safe driving assistance system according to the present invention.

As shown, the safe driving assist system of the present invention includes a driving influence factor measuring unit 10 for detecting a driving influence factor of the elderly driver. The present invention includes a safe driving determination unit 20 for determining the current mental, emotional, and physical conditions of an aged driver in a driving state using the measured driving influence factors. The present invention includes a safe driving support reaction unit 30 for supporting safe driving based on a result of the determination by the safe driving determination unit 20.

First, the elderly driver aboard the vehicle mounts the mobile communication terminal 21 such as a smart phone at a designated position so as to collect the value detected from the operation influencing factor measuring unit 10. [ Also, the mobile communication terminal 21 is configured to automatically connect to the safe driving support reaction unit 30 as well. Preferably, this configuration is preconfigured to be made through an electrical connection at the designated location.

The driving influence factor measuring unit 10 may measure the driving influence factor using the existing equipment installed inside or outside the vehicle, the black box 11, the living body sensor 12, the navigation system 13, , And a driving influence factor according to the physical part is detected.

FIG. 4 shows a detailed configuration of a driving influence factor measuring unit in the safe driving assist system according to the present invention.

The driving influence factor measuring unit 10 of the present invention is a configuration for measuring the driving influence factor of the aged driver by using existing equipment installed in the vehicle, among other things. The black box 11 is equipped with a camera. It is possible to monitor the external traffic environment through the black box 11. That is, the camera built in the black box 11 is capable of photographing the traffic light condition at the intersection and the surrounding traffic situation.

The navigation 13 is capable of detecting the current position information of the vehicle. Also, it is possible to check an intersection, a traffic situation, and the like in front of a certain distance according to the traveling direction of the vehicle through a traffic information module (not shown) mounted on the navigation.

The intersection signal light information photographed through the black box 11 and the position information along the traveling direction of the vehicle through the navigation unit 13 to detect time information required for the vehicle to pass through the intersection at the current position . Also, the change of the traffic light can be photographed through the black box 11, and the speed or the like corresponding to the change in traffic lights of the aged driver can be detected using this information.

It is possible to detect the relative reaction speed and the like compared with the flow of the surrounding vehicle to the intersection traffic light of the aged driver. For example, when passing through an intersection based on intersection signal light information photographed through the black box 11, it can be determined that the vehicle travels too slowly compared with the flow of the surrounding vehicle. Also, when the intersection needs to be stopped first based on the intersection signal light information photographed through the black box 11, the time when the vehicle is first stopped can be detected from the point of time when the display information of the traffic light changes. This detection information makes it possible to determine the reaction speed or the like with respect to the signal lamp of the aged driver.

Also, the number of times the signal is violated is determined by failing to respond to the change of the traffic light. It is possible to check the current state of the traffic light through the black box 11 camera and to detect the current number of times the vehicle has been violated by detecting the vehicle state (stop, running).

Further, by using the black box 11, it is possible to secure the headway distance to the next vehicle through the photographing information. Then, during the present guiding operation, the number of times of deviation from the predetermined distance between the vehicle and the predetermined distance is determined. This is because older drivers tend to cause traffic congestion by spacing the inter-vehicle distance longer than necessary. In determining the number of times of inter-vehicle distance uncertainty, various sensors installed in the vehicle may be used. For example, detection information of sensors installed in the vehicle such as an inter-vehicle distance detecting sensor and a speed sensor may be used. Therefore, the driving influence factor measuring unit of the present invention means that it includes the configuration of various sensors installed in the existing vehicle.

The biometric sensor 12 is installed in various places in the vehicle. In particular, the heart rate sensor 121 detects the heart rate to measure the physical condition of the driver. It is preferable that the heart rate sensor 121 is installed at the handle portion where the driver's hand always touches. That is, it is possible to detect the heart rate at the same cycle as the heart rate in the capillary blood vessel (peripheral blood vessel) of the finger by using a pressure sensor or the like.

Further, a temperature sensor 122 is provided to detect the temperature of the driver. The temperature sensor 122 can be installed anywhere in the vehicle where the body temperature of the driver can be detected. For example, an infrared temperature sensor can be mounted on the windshield of a vehicle to detect the temperature of the driver. Alternatively, a temperature sensor may be provided on the vehicle handle to detect the body temperature of the driver.

The SpO2 sensor 123, which detects the degree of oxygen saturation, is installed on a handle, a watch, or the like, calculates a measured value for a predetermined time, and displays the output as an output. The light emitted from the light emitting unit included in the SpO2 sensor 123 passes through the blood vessel between the driver's fingers and is detected through the light receiving unit. The hemoglobin combined with oxygen absorbs infrared rays, while the reduced hemoglobin absorbs more red light Using the property, the difference of the light is measured and the value of SpO2 is calculated. Therefore, the SpO2 sensor is also installed at an appropriate position where signal detection from the driver in the vehicle is easy.

In addition, the driving influence factor measuring unit 10 may further connect various measuring devices installed in the vehicle to detect the driving influence factor index according to the mental, emotional, and physical changes of the driver.

The operation influence factor index detection will be described below again.

The safe driving determination unit 20 shown in Fig. 3 is a configuration using the mobile communication terminal 21 of the driver.

The mobile communication terminal 21 is a portable terminal, and can be a smart phone, a tablet PC, a notebook, or the like of a driver. Therefore, since the mobile communication terminal 21 is configured independently for all the drivers, it is in a state customized for all the drivers. This is because the health information of the driver is monitored through the linkage with the healthcare application of the driver stored separately in the mobile communication terminal 21 and utilized for the safe driving assistance system of the present invention.

The mobile communication terminal 21 is provided with a running app of the safe driving assist system according to the present invention. The app is configured to be additionally updateable. The app is downloaded from a separate server (not shown). When the safe driving support mode signal is selected from the driver, that is, when the application is activated, the app performs control according to the following operations.

The app inputs various data influencing the operation from the operation influencing factor measuring unit 10. [ And collects and analyzes the inputted driving influence factor information. And quantify the driving influence factor index according to the analyzed result. Then, the safe driving support reaction unit 30 is activated using the quantified values.

The safe driving support reaction unit 30 shown in FIG. 3 is a part of a control configuration for supporting safe driving of the vehicle by receiving an instruction from the mobile communication terminal 21. As shown in FIG.

The safe driving support reaction unit 30 performs safe driving support assistance using the safe driving support reaction control signal provided by the mobile communication terminal 21. [ The safe driving support reaction unit 30 includes an ECU 31. The ECU 31 is already installed in the vehicle. That is, ECU 31, which is provided for controlling electronic components inside the automobile, is used. Of course, it is also possible to have a separate additional ECU, but it is preferable to use an existing device rather than an additional one in the cost saving part. Therefore, in order to minimize the load from the operation of the safe driving assist system according to the present invention, the existing ECU 31 configured to control the operation of the vehicle receives only the control signal provided from the mobile communication terminal 21 .

A speaker 32, an emergency light 33, a display 34, etc. may be included in the safe driving support reaction unit 30 under the control of the ECU 31. [ The speaker 32 and the emergency light 33 are all provided in existing vehicles. The speaker 32 is used to sound a horn. And the display 34 is arranged at the rear as shown in Fig. That is, a message for informing the outside of the vehicle of the current state of the aged driver in the vehicle.

In addition to this configuration, the safe driving support reaction unit 30 of the present invention includes a traffic voice guidance module 22. The traffic voice guidance module 22 is a voice guidance configuration for various safety driving assists used in a safe driving support described later. The traffic voice guidance module 22 can use the voice service configuration included in the mobile communication terminal 21 or use the voice service configuration using the speaker already installed in the vehicle. What is important here is that the voice guidance service is supported for safe driving assistance under the control of the mobile communication terminal.

FIG. 5 shows a state diagram of an assistant driving mode for the elderly in the safe driving assist system according to the present invention.

And FIG. 6 is a diagram illustrating assistance operation control relationships for the elderly in the safe driving assistance system according to the present invention.

In the safe driving assist system of the present invention, the configuration of the safe driving assist is divided into four stages. As shown, includes a normal driving assist mode 41, a warning driving assist mode 42, a warning driving assist mode 43, and a dangerous driving assist mode 44.

The driving assist mode is a configuration suitable for the elderly driver and is divided into a plurality of driving assist modes. To this end, a reference value is determined for each of the driving influence factor index determination factors for determining the driving assist mode.

The mobile communication terminal 21 collects and analyzes the detection value of the operation impact factor measurement unit 10, determines a driving assist mode according to the determination result, and transmits the driving assistance mode to the ECU 31. The ECU 31 controls the safe driving support reaction unit 30 according to the driving assist mode control value provided by the mobile communication terminal 21. [

The normal operation assist mode 41 may be described as a general operation control process. In the normal driving assist mode 41, the same effect can be obtained even when the aged driver is driving and the assistant driver is not on board.

For example, a front traffic light in the vehicle running direction is photographed through a camera mounted on the black box 11. The intersection in front of the current position of the vehicle in the vehicle traveling direction can be confirmed by using the navigation unit 13. Using this information, it is possible for the app to inform the driver of the color of the traffic light before a certain time before entering the intersection according to the driving direction of the vehicle. If you change from green light to orange before a certain time to enter the intersection, you will be guided by the voice saying, "Driver, please be careful." If you change from red light to green light, you can give a voice guidance saying, "Driver's departure is green light." If the traffic light at the intersection is red light, you can say "Stop the driver, it's red light." Such voice guidance can be made directly under the control of the mobile communication terminal 21 through the traffic voice guidance module 22. Alternatively, the voice guidance may be made through the speaker 32 under the control of the ECU 31. Recent research has shown that providing voice guidance to older drivers is more effective and less confusing than providing visual guidance.

When the driving influence mode index is included in the range of the driving assistance mode, the mobile communication terminal 21 continuously monitors the operation of the vehicle, (21). ≪ / RTI >

The driving assist mode 42 includes a voice guidance control process performed through the traffic voice guidance module in the normal driving assist mode 41. [ In addition, the driver performs control to focus on driving. As an example, it is possible to give voice guidance while driving. As another example, it is possible to carry out control to turn on music that can be focused on driving. The music control performed in the driving assist mode 42 may be controlled through the speaker 32 to store the preset music. At this time, the music to be reproduced can be stored in advance. Further, it is possible to classify the selection music for preventing sleepiness of the driver, the selection music for calming the excited state of the driver, and the selection music for allowing the driver to concentrate on driving, and control the corresponding music to be reproduced based on each judgment Do.

The warning driving assistant mode 43 continuously monitors the operation of the vehicle by the mobile communication terminal 21 and analyzes the collected information so that when the driving influence factor index is included in the range of the warning driving assistant mode, (21). ≪ / RTI >

The warning driving assisting mode 43 includes a traffic voice guidance in the driving assisting mode in the past, and a control process for music reproduction so that the driver can concentrate on driving. In addition, it includes warning control to the driver, and also allows the outside of the vehicle to recognize it.

For example, the emergency light 33 maintains the blinking state, and recognizes that the vehicle is in an emergency situation not only in the driver but also outside the vehicle, and guides other drivers located in the vicinity of the vehicle to be careful.

In addition, in the warning driving assist mode 43, the warning message " Please pay attention to the driver " Such a warning message may be similarly controlled in the driving assist mode 42 of the above-noted state.

The dangerous driving assist mode 44 continuously monitors the operation of the vehicle by the mobile communication terminal 21 and analyzes the collected information. When the driving influence factor index is included in the range of the dangerous driving assist mode, (21). ≪ / RTI >

The dangerous driving assist mode 44 is a case in which it is determined that the elderly driver can no longer drive the vehicle. In this case, the message is delivered to the outside quickly, and control to stop the vehicle operation is performed. Of course, it outputs a warning voice to the driver in the vehicle to notify the driver of the danger. And controls the blinking of the emergency light to inform the outside of the vehicle that the vehicle is in an emergency situation. By displaying a warning phrase on the rear display of the vehicle, it is possible for the rear vehicle to know the occurrence of a dangerous situation in the front vehicle. Alternatively, the mobile communication terminal may automatically transmit a telephone call to the safety center (119 emergency center) for requesting assistance.

The control values of the automobile electronic components including the speaker, the display, the emergency light, etc. in the automobile for each driving assist mode can be stored in the internal memory of the ECU 31 or in a separate memory. It may be stored in a memory inside the mobile communication terminal 21. [

FIG. 7 shows the relationship of the factors for determining the driving influence factor index in the safe driving assistance system according to the present invention.

The safe driving assist system for the elderly according to the present invention determines the driving influence factor index value based on the measured value of the driving influence factor measuring unit 10 and calculates a normal driving assist mode, The driving assist mode, the warning driving assist mode, and the dangerous driving assist mode are controlled.

The driving influence factor index value is determined on the mental side, the emotional side, and the physical side as shown in Fig. The mental aspect is a part for confirming the driver's cognitive ability. The emotional aspect is a part for confirming the state of emotion such as driver's anger / excitement state. The above physical aspect is a part for practically applying it to the determination of the driving influence factor index because most of the elderly aged people have chronic diseases.

The driving influence factor exponent value of the mental aspect is determined by various operating factors of influence factors, for example, the detection value such as the number of signal violations, the corresponding speed of signal changes, and the number of direction indicator mismatches.

The signal violation count detects the traffic light information at an intersection or a board through the camera of the black box 11. It is possible to judge whether the signal is violated by judging in real time the detected signal light information and the driving state of the corresponding vehicle at the intersection or the board. The number of signal violations may be the number of signal violations occurring during the current running, or may be the number of signal violations during a certain period of time.

The number of signal violations detected in the above process (a) is given as a weight (a ') which is previously set to determine the driving influence factor index value in terms of mental aspects, Is determined as an initial value (A) to be determined.

That is, weights of different values determined according to the experimental values are given to the factors of the driving influence factor index for determining the driving influence factor index value in the mental aspect, and the weighted value is used as the driving influence factor Is used to determine the exponent value.

The corresponding speed (b) for the signal change detects the traffic light information at the intersection or the board through the camera of the black box 11. Also, it is possible to detect the current position information of the vehicle, the intersection before the predetermined section in the vehicle running direction, and the pedestrian press information through the navigation unit 13. Also, the flow information of the surrounding vehicle can be detected through the camera mounted on the black box 11. Based on such information, a time at which a change in motion of the vehicle occurs at a point of time when a traffic light change occurs, and a speed corresponding to a signal change of the vehicle through a relative speed with respect to the movement of the vehicle (b) can be detected.

The corresponding speed (b) of the signal change detected by the above process is given by a predetermined weight (b ') to determine the driving influence factor index value in the mental aspect, Is determined as an initial value (B) for determining an exponent value.

The inter-vehicle distance non-compliance value (c) detects the inter-vehicle distance from the preceding vehicle using the detection image of the camera of the black box 11. However, the present invention is not limited to this, but an inter-vehicle distance from the vehicle ahead is detected using an inter-vehicle distance detecting sensor installed in the vehicle. It is also possible to detect the headway distance from the vehicle ahead through a black box equipped with a near-field radar sensor that measures the distance to the vehicle ahead. The detected inter-vehicle distance is calculated by comparing the value of the detected inter-vehicle distance with the value of the inter-vehicle distance from the preceding vehicle on the road safety law. The non-compliance value (c) of the inter-vehicle distance may be the number of non-compliant times in accordance with the comparison with the set value.

(C), which is detected by the above procedure, is given a predetermined weight (c ') to determine the driving influence factor index value in terms of the mental side, so that the driving influence factor index Is determined as an initial value (C) for determining a value.

In a similar process, all of the initial values that determine the driving influence factor exponent values included in the driving influence factor exponent determining element of the mental aspect are determined, and these initial values are all computed (as an example). Then, the weighted value (30%) assigned to the mental aspect is given to the calculated value (A + B + C ....) to calculate the driving influence factor index value in the final mental aspect.

Likewise, the driving influence factor exponent value calculation process is performed on the driving influence factor exponent value determining elements of the emotional aspect.

The driving influence factor index value of the emotional side is determined by various driving influence factor measurements, for example, a sudden increase in heart rate, an increase in body temperature, and a sudden shouting sound.

The sudden increase value of the heart rate can be obtained from the detection value of the biometric sensor 12. [ The reference heart rate value of the aged driver for detecting the sudden increase value of the heart rate can be detected on the basis of the heart rate value detected at the beginning of the vehicle operation or the preset reference value.

The sudden increase (d) of the heart rate detected in the above process is given by the weight (d ') set in advance to determine the driving influence factor index value in the emotional aspect, so that the driving influence factor index Is determined as an initial value (D) for determining a value.

That is, a weighting value of each of different values determined according to the experimental values is given to the driving influence factor index determining factors for determining the driving influence factor index value in the emotional aspect, and the weighted value is a driving influence factor Is used to determine the exponent value.

The rising value of the body temperature can be obtained from the detection value of the living body sensor 12. [ The reference body temperature value of the aged driver for detecting the increase value of the body temperature can be detected on the basis of the body temperature value detected at the beginning of the vehicle operation or the preset reference value.

The rising value (e) of the body temperature detected in the above process is given a predetermined weight (e ') to determine the driving influence factor index value in the emotional aspect, thereby determining the driving influence factor index value in the emotional aspect Is determined as an initial value (E).

Also, the sudden shout sound generation value can be obtained by detecting the size of sound input through the sound input unit (microphone of the mobile communication terminal, etc.) installed in the vehicle. Of course, in this case also, a reference value for detecting the size of sound needs to be set.

The sudden shout sound generation value f is set to a predetermined value f 'to determine a driving influence factor index value in an emotional aspect, so that an initial value < RTI ID = 0.0 > (F).

In a similar process, all of the initial values for determining the driving influence factor exponent values included in the driving influence factor exponent value determining element of the emotional aspect are determined, and these initial values are all operated (added as an example). Then, the weighted value (30%) assigned to the emotion side is assigned to the calculated value (D + E + F + ....) to calculate the driving influence factor index value in the final emotion side.

Finally, the driving influence factor exponent value in the physical aspect is detected through the biological sensor 12 by a change in heart rate, a change in SpO2, an increase in blood pressure, and a monitoring of blood glucose information. Then, weights assigned to different values are assigned to the detected values to calculate the driving influence factor exponent value in terms of physical aspects, and the initial values of the respective driving influence index determining factors are determined.

In this process, all of the initial values for determining the values of the driving influence factor index included in the factor of determining the driving influence factor value of the physical aspect are determined, and these initial values are all operated (added as an example). Then, the weight value (40%) assigned to the physical aspect is added to the calculated value to calculate the driving influence factor index value in the final physical aspect.

As a result of the above process, the driving influence factor index value, the driving influence factor index value in the emotional aspect, and the driving influence factor index value in the physical aspect were determined on the mental side. The three driving influence factor values thus determined are computed (as an example), and the final driving influence factor exponent value is determined.

The final driving operation influencing factor exponent value is determined to which range of the predetermined mode determination exponent boundary value, and mode determination is performed according to the inclusion range.

In FIG. 7, the driving influence factor index value according to the mental aspect is given as 30% of 100% of the driving influence factor index value according to the experimental values. In addition, the driving influence factor index value according to the emotional aspect was given 30% of the total driving factor index value 100%, and the driving influence factor index according to the physical aspect was 40% of the driving influence factor index value 100% Respectively.

Also, in FIG. 7, the boundary value of the driving influence factor index, i.e., the exponential boundary value for mode determination is set to 40 points or less in the normal driving assist mode. CAUTION In the driving assist mode, set the driving influence factor exponent value from 41 to 60 points. Warning The driving assist mode sets the driving influence factor exponent value from 61 to 80 points. Danger The driving assist mode sets the driving influence factor exponent value from 81 points or more.

7, reference values, weights, and set values used for determining the driving assist mode are stored through a memory of the mobile communication terminal or a memory of the ECU and a separate external memory.

Next, a description will be made of an operation process in which the safe driving assistance assistance for the elderly is performed according to the present invention.

The application of the safe driving assist system of the mobile communication terminal 21 receives the safe driving support mode signal from the driver and is executed.

When the app is activated, the app collects data for all elements included in the driving influence factor exponent. The data at this time is based on the detection values of the black box 11, the navigation unit 13, and the biometric sensor 12.

First, the present invention has concretely derived driving factor index factors as one embodiment.

Among the determinants of the driving influence factor index, mental aspects were applied to the number of signal violations, the response speed to the signal changes, and the number of non - compliance of the inter - vehicle distance. That is, a plurality of factors for determining the driving influence factor index may be set, and the driving factor may be selected and applied to the aged driver.

The number of signal violations is determined by scoring the number of violations of the signal by the aged driver during the current operation based on the camera mounted on the vehicle black box. For example, three points are awarded for each violation, and the maximum is set at 15 points.

The corresponding speed for the signal change detects the traffic light information and the real-time vehicle driving information at the intersection using the camera mounted on the vehicle black box. For example, the number of times the elapsed driver responds to a signal change by more than 2 seconds is scored based on the signal light conversion time point. For example, two points are assigned to each delay, and the highest point is set to 10 points.

The number of times of non-compliance of the inter-vehicle distance is detected in real time by using the camera mounted on the vehicle black box. For example, the distance to the front vehicle is detected in real time while driving on the road. If the appropriate inter-vehicle distance is set to 10M during operation, the number of times that the difference of the inter-vehicle distance such as 5M or more or 15M or more is wrong by 50% or more is counted. One point is given for each violation, and the highest point is set at 10 points.

Through the above example, scores for three factors of driving influence factor index in mental aspect are calculated during the current operation. The score for this mental aspect is determined to be between the lowest value of 0 and the highest value of 30.

Next, in the embodiment of the present invention, the elements for determining the driving influence factor index on the emotional side apply values for a sudden increase or decrease in heart rate, an increase in body temperature, and a sudden shout.

The sudden increase or decrease in the heart rate is detected in real time by the heart rate sensor installed in the vehicle and gives a score according to the increase or decrease of the heart rate. 10 points for less than 50 times per minute, 6 points for 50 to 60 times, 3 points for 60 to 70 times, and 0 point (normal value) for 70 to 80 times. 3 points are given for 80 to 90 points, 6 points for 90 to 100 points, and 10 points for 100 points or more. The application of the normal 70 to 80 times the heart rate indicates that the embodiment of the present invention is applied to the elderly driver and is set slightly higher than the normal adult reference value.

The rising value of the body temperature is based on the detected temperature of the infrared body temperature sensor attached to the windshield of the vehicle or the like. Two points are given every 1 degree rise based on 36 degrees and scored. For example, 0 points below 36 degrees, 2 points at 37 degrees, 4 points at 38 degrees, and 10 points at above 39 degrees. This is because the sudden rise in body temperature is very lethal for older drivers, so we set the highest point above 39 degrees.

The sudden shout sound detection value measures a noise of a voice detected through a microphone installed in a vehicle or a microphone of a mobile communication terminal. As an example, the noise measurement can be detected through a noise measurement application installed in a mobile communication terminal, and a score is given to a voice over a certain decibel (dB). For example, 0 points below 60 decibels, 2 points below 80 decibels, 4 points below 100 decibels, 6 points below 120 decibels, and 10 points above 120 decibels.

In the above embodiment, scores for the three driving influence factor determining factors of the emotional aspect are calculated. The score for this emotional aspect is determined to be between the lowest value of 0 and the highest value of 30.

Next, in the embodiment of the present invention, the factor of determining the driving influence factor of the physical aspect is a chronic disease of the elderly due to abnormal heart rate, low oxygen saturation, hypertension, hypoglycemic shock, and the like.

The driving influence factor index determining elements of the physical aspect can be detected using a wristwatch-type sensor and transmitted to the mobile communication terminal. Recently, high-quality mobile communication terminals also have a sensor function capable of detecting the heart rate, oxygen saturation, blood pressure, blood sugar, and the like. These configurations can be used to detect values for the required physical aspects of the driving influence factor exponent determinants.

The abnormal heart rhythm is a danger signal from arrhythmia, tachycardia or bradycardia. For example, a pulse of more than 100 beats per minute (tachycardia) can cause heart disease or sudden death. Conversely, bradycardia less than 50 beats per minute causes dizziness or syncope.

The sudden increase or decrease in the heart rate is detected in real time by the heart rate sensor installed in the vehicle and gives a score according to the increase or decrease of the heart rate. 10 points for less than 50 times per minute, 6 points for 50 to 60 times, 3 points for 60 to 70 times, and 0 point (normal value) for 70 to 80 times. 3 points are given for 80 to 90 points, 6 points for 90 to 100 points, and 10 points for 100 points or more. The application of the normal 70 to 80 times the heart rate indicates that the embodiment of the present invention is applied to the elderly driver and is set slightly higher than the normal adult reference value.

The low oxygen saturation (SpO2), for example, can measure blood oxygen saturation through a living body sensor implemented as a wristwatch type and transmit it to a mobile communication terminal. For example, a blood oxygen saturation of 95% to 100% is judged to be normal, and a score of zero is given. 90% to 95% of blood oxygen saturation is judged abnormal and 5 points are given. A blood oxygen saturation of 90% or less is judged as a dangerous condition and a score of 10 is given.

The hypertension may cause a stroke. Therefore, it is possible to measure the blood pressure through the blood pressure measuring sensor, which is implemented as a wristwatch type, and transmit it to the mobile communication terminal. A systolic blood pressure of 140 mmHg or more is considered a hypertensive state and is given a score of 10. A blood pressure of 130 to 140 is judged to be a high blood pressure and 5 points are given. A range of 110 to 130 is judged as a normal state and a zero point is given. In the range of 100 to 110, a low blood pressure is judged and 5 points are given. A value of 100 mmHg or less is judged as hypotension and a score of 10 is given.

The state of hypoglycemic shock due to diabetes is judged based on blood glucose measurement data. The blood glucose measurement can be performed through a blood glucose measurement sensor implemented as a wristwatch type and transmitted to a mobile communication terminal. The blood glucose level is judged to be less than 100 mg / L as normal, and 0 point is given. When the detected blood sugar is 100 to 110, it is judged to be slightly higher, and 3 points are given. In the range of 110 to 120, it is judged that the blood glucose level is middle, and 5 points are given. If the range of 120 ~ 130 is high, 7 points are given. If a blood sugar value of 130 or more is detected, it is judged to be hyperglycemic and 10 points are given.

In the above embodiment, scores for the four factors of driving influence factor index on the physical side are calculated. The score for this physical aspect is determined to be between the lowest value of 0 and the highest value of 40.

As described above, the scores of the mental aspects, the emotional aspects, and the physical aspects are determined, and when these values are added, the final driving influence factor index value for the aged driver is determined.

The mobile communication terminal 21 outputs the driving assist mode value determined by the ECU 31 when the driving assist mode is determined. The ECU 31 controls the operation of the automobile parts based on the stored control value according to the determined driving assist mode.

In the normal driving assist mode 41 of the vehicle, the traffic situation along the traveling direction of the vehicle is analyzed through the detection signals of the black box and the navigation. Then, the analyzed traffic situation is guided by voice and serves as an assistant driver of the aged driver. In the case of elderly drivers, it is difficult to cope with situations where attention is weak and imminent. Therefore, when a voice guidance is given so as to maintain a change of a traffic light, an interval between vehicles, and a traveling line, an effect of assisting an aged driver in driving the vehicle can be obtained.

In the driving assist mode 42 of the vehicle, the assistant driver performs an auxiliary driving operation so that the driver can concentrate on the driving at an appropriate interval at an appropriate distance. At this time, in addition to the process performed in the normal driving assist mode, the driver turns on predetermined music or outputs a warning voice message to induce the driver to concentrate on driving.

In the warning driving assist mode 43 of the vehicle, in addition to the process performed in the driving assist mode described above, the driver and the surrounding other drivers can further perform the blinking operation of the emergency light so that the warning operation for the vehicle can be performed.

In the dangerous driving assist mode (44) of the vehicle, an emergency call number (119) which is previously set can be automatically dialed to inform the outside of the dangerous situation. In addition, a warning message is displayed on the rear display to inform the driver of the danger of the vehicle ahead. In addition to this, it is possible to control the sounding of the horn using the speaker and the flashing operation of the emergency light.

As described above, the present invention allows the aged driver to perform the same function as the assistant driver when driving. In particular, driving assistance is controlled so that safe driving can be performed based on the health condition of the elderly driver individually.

On the other hand, the present invention focuses on assisting an elderly driver in safe driving of the vehicle. In the embodiment described above, it is based on a value being measured through a driving influence factor measuring part for determining the exponent value of the driving influence factor index determining factors.

However, it is not always based on measured values measured through the operating influence factor measuring part. For example, elderly drivers may have chronic illnesses. Therefore, it is also preferable to determine an initial value for the chronic disease of the aged driver in advance and use it in the determination of the safe driving assist mode.

As an example, in the process of detecting the values of the factors for determining the driving influence factor index of the present invention, the driving factor index factor for the physical aspect is obtained by applying the exponential value of the chronic driver ' It can also be used to determine factor index values.

That is, the elderly driver may preliminarily apply the usual diabetic value to determine the score. Therefore, when the usual diabetic level of the elderly driver is included in the range of 110 to 120, adding the values of the other factors of driving influence factor determining factor in the physical aspect is calculated in advance.

It is also possible to determine the score by applying the usual blood pressure value of the elderly driver in advance. Therefore, when an older driver's blood pressure is included in a high blood pressure state in the range of 130 to 140, add another value of the factors to determine the driving influence factor index, with 5 points preliminarily calculated on the physical side.

Therefore, in the case of the elderly driver who has chronic diseases due to hypertension and diabetes, it is preferable to add the calculated values of the factors for determining the other factors of influencing factors when the diabetes and blood pressure values are calculated in advance Do.

Thus, it is also possible to configure the driving factor index factor of the physical aspect to be influenced by the health condition that the older driver usually has.

In the process of detecting the values of the factors for determining the driving influence factor index of the present invention, the factors for determining the driving influence factor index for the mental aspects are determined by cumulatively calculating the portions generated during the last five driving operations, . In this case, the parameter for determining the driving influence factor exponent value can be changed according to the cumulative operation condition.

That is, the number of times the signal is violated during the last five times of the number of signal violations can be accumulated and scored. Likewise, it is possible to cumulatively count the cases in which the response speed to the signal change, the headway distance uncertainty frequency, and the like occurred during the last five times of operation.

This is an index value for judging the cognitive ability of the aged driver so as to be based not only on the current driving state but also on the judgment value according to the driving state during the recent period. In this way, it is also possible to configure the driving factor index factor of the mental aspect to be influenced by the cognitive ability that the older driver usually has.

In addition, the factor of determining the driving influence factor index can be used by adjusting the variable according to the tendency of the aged driver. For example, the factor of determining the driving influence factor index for the mental aspect can be changed to the number of the direction indicator mismatch by replacing the number of the headway distance uncertainty.

The direction indicator mismatch count detects the driving information of the vehicle in real time using the camera mounted on the vehicle black box. For example, it detects in real time the state of vehicle operation at an intersection. Then, the on / off state of the turn signal lamp of the vehicle at the intersection is detected. Based on this information, the driving direction of the current vehicle is compared with the state of the turn signal lamp, and the aged driver detects the number of mismatches of the turn signal lamp during the current operation. For example, one point is given per mismatch and the maximum point is set as 10 points.

In addition, health information for the driver is required to configure the driving factor of the physical aspect to be influenced by the usual health condition of the elderly driver.

For this purpose, the mobile communication terminal 21 needs to store the health information of the driver. Therefore, the mobile communication terminal 21 has secured, set, and stored health information of the aged driver and a risk judgment range based on the health information in advance. For example, when the elderly driver has a high blood pressure, the normal blood pressure value of the elderly driver is stored and basically calculates the driving influence factor index value based on the blood pressure. In order to determine hypoglycemic shock status, the blood glucose measurement result of the elderly is stored, and the index of the driving influence factor by the blood glucose is calculated based on the value.

The health information of the elderly driver can be provided as health information for the elderly driver at an authorized center. That is, the health information corresponding to the elderly driver can be obtained by various methods and used in an app of the driving assistance system. The health information of the aged driver and the risk judgment range determined on the basis of the health information are stored in the internal memory of the mobile communication terminal and then used for application operation of the safe driving assist system.

In addition, in order to configure the mental aspects of driving factor index factors to be influenced by the cognitive ability of older drivers, it is necessary to accumulate information about the drivers. For this purpose, it is necessary to store information using a storage area of the mobile communication terminal 21 or a separate memory (not shown).

In the embodiment of the present invention, the driving factor determining factor, the driving factor determining factor, and the driving factor determining factor of the physical aspect that are applied to the mental aspects can be changed through the updating process. Also, the reference value for deriving the score value of the exponent determination factors may be changed in the updating process.

This is because it is natural that the driving influence factor of the aged driver changes according to the elapse of time, and therefore, it is necessary to update it in a predetermined time unit. The determination update for determining the operation mode can be sufficiently performed through a process of updating a used application of the mobile communication terminal through a server (not shown).

Accordingly, the foregoing detailed description should not be construed in any way as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
