Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an autonomous driving control system and a method for improving user safety,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an autonomous drive control, and more particularly, to an autonomous drive control system and method for improving user safety for controlling an autonomous drive mode based on a driver's drinking state.

The autonomous mobile market is expected to enter full-scale growth from 2020. It is estimated that the world autonomous vehicle market will reach $ 1.2 trillion by 2035 after accounting for 2% of the total automobile market in 2020, which is estimated to be $ 200 billion, and most cars will be replaced by autonomous vehicles in the near future. do.

These autonomous cars are designed to be able to use both autonomous and manual driving before the era of autonomous driving. The reason is that even if fully autonomous driving is performed 100%, if the autonomous driving judgment due to mechanical (electronic) error is wrong, the person should be able to control the vehicle directly. Secondly, Because there are so many people there is a need for a passive driving mode that allows people to drive themselves.

On the other hand, drunk driving is a driver 's obligation under the law that no one should drive an automobile while drunk. In relation to this, regarding the method of measuring drunk driving, there are related patents related to prevention of drunk driving through blood, breathing, and blood in the inside and outside of the vehicle, such as a drinking measurement unit, an auxiliary device,

Referring to FIG. 1, a technology called Sober Steering developed by a parent company of Canada is developed to prevent a drunk driving by implanting a sensor for detecting alcohol concentration by analyzing the skin and respiration of a driver on a steering wheel and a start button . Blood alcohol concentration is detected as soon as the start button is pressed. When the alcohol concentration is higher than the reference, the start is restricted and the vehicle speed is decreased.

Referring to FIG. 2, Nissan also discloses techniques for detecting alcohol odor, driver face detection, steering wheel detection, and the like to prevent drunk driving. There are four sensors on the vehicle, so that the driver automatically senses the odor when the driver is in the car. The sensor built into the transmission detects the alcohol emitted by the driver's palms and the vehicle can not move if the detected value is above the specified value.

However, these conventional techniques are limited to the engine to be controlled by the operation control of the vehicle. Therefore, the conventional techniques are limited to the future automobile in which the engine is controlled without the operation of the vehicle, that is, autonomous vehicles.

Therefore, there is a need to develop a technology for controlling the vehicle itself, regardless of the operation of the vehicle, in order to prevent drunken driving controversies and accidents in future vehicles such as autonomous vehicles.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention. The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, terms and words used in this specification and claims are to be interpreted relative to the technical idea of the present invention based on the principle that the inventor can properly define the concept of the term to describe it in the best way of its own invention It should be interpreted in terms of meaning and concept. In the following description, well-known functions and constructions are not described in detail to avoid obscuring the subject matter of the present invention.

3 and 4, an autonomic driving control system for improving user safety according to an embodiment of the present invention includes a vehicle V, a drinking state determination unit 100, a driving mode setting unit 200, (300).

The vehicle V may be a vehicle capable of operating in a mode in which the driver operates the vehicle directly or in an autonomous mode. In addition to the mode for directly operating the vehicle, the autonomous driving mode is also configured as a possible vehicle, which is a factor for preventing the debate and accident of drinking driving in future vehicles. In this case, the vehicle (V) is intended for the autonomous driving mode to implement the autonomous driving mode, but it can be applied to various smart vehicles that are future cars.

The drinking state determination unit 100 may be mounted on the vehicle V and may sense the breathing state of the driver to determine the drinking state. This is a component for providing a more objective drinking state determination result by utilizing the method of determining the drinking state through breathing of the driver used for the alcohol interception.

At this time, the drinking state determination unit 100 may include a driver recognition unit 110, an amount measuring unit 130, and an alcohol concentration value measurement unit 150.

The driver recognition unit 110 can detect whether a driver is seated and recognize a driver who wants to sense breathing. This is a component for detecting respiration when the driver is seated in the vehicle V, that is, when he / she is about to drive. Or if the passenger has a passenger other than the driver in the vehicle V, it is a component for accurately identifying the person who intends to operate the vehicle. At this time, the driver recognition unit 110 may be combined with various auxiliary measurement means such as a method for measuring the alcohol consumption by the skin.

On the other hand, the driver recognizing unit 110 detects whether or not the driver is seated by using various sensors such as a pressure-reducing sensor and the like, which can be installed inside the vehicle.

The exhale amount measuring unit 130 can measure the exhaled amount of the recognized driver. This is a component for objectively measuring blood alcohol concentration using exhalation.

The alcohol concentration value measuring unit 150 can measure the alcohol concentration value included in the measured driver's exhalation. This is a component to determine the alcohol status of the driver by measuring the alcohol concentration value contained in the exhalation.

The driving mode setting unit 200 can set the driving mode to limit the driving mode of the driver based on the determined drinking state. This can be said to be a constituent element for prevention of drunk driving controversy and accident through control of the vehicle itself, that is, autonomous driving control.

The driving mode setting unit 200 may include an autonomous driving mode setting unit 210 and a performance mode setting unit 230.

The autonomous mode setting unit 210 may set the driving mode of the vehicle V to the autonomous driving mode if the measured alcohol concentration value is equal to or greater than a predetermined concentration value.

The performance mode setting unit 230 may set the driving mode of the vehicle V to the performance mode when the measured alcohol concentration value is smaller than a preset concentration value.

The autonomic driving mode setting unit 210 and the performance mode setting unit 230 are components for providing an optimum driving mode by comparing the numerical drunk driving state of the driver with a predetermined comparison target value.

On the other hand, when the vehicle V is controlled in the execution mode, the driving state determination unit 100 may be repeatedly performed to change or maintain the running mode of the vehicle V. [ This is a feature that allows you to maintain safety until the end of the journey through continuous drinking measurement. Particularly, the repetitive execution of the drunk state determination unit 100 is a feature for preventing the drunk driver from performing the drunk driving after the driver drank the operation mode in which the driver directly operates the vehicle.

Accordingly, the vehicle control unit 300 can control the vehicle V according to the set travel mode.

The vehicle control unit 300 can control the vehicle to change the traveling mode of the vehicle V to the autonomous traveling mode and move to the address preset by the user if the control of the vehicle V is not performed even after a certain period of time . This is a feature for letting the driver return home through autonomous driving when it is determined that the driver is in the dull state when there is no adjustment for the vehicle V for a predetermined time.

At this time, the control of the vehicle V may be referred to as a direct control of the driver including an engine button, a handle, and a brake operation.

5, the autonomic driving control system for improving user safety according to an embodiment of the present invention includes a vehicle V, a drinking state determination unit 100, a driving mode setting unit 200, a vehicle control unit 300 And a passenger drunk state determination unit 400 in addition to the passenger drunk state determination unit 400.

The passenger drunk state determination unit 400 can determine the drunk state of the passenger powering the vehicle V in addition to the driver. This is a component considering the fact that the person boarding the vehicle V is not limited to one driver. At this time, the passenger drunk state determination unit 400 performs the same process as that of the driver recognition unit 110, the amount-of-vomit measurement unit 130, and the alcohol concentration value measurement unit 150 included in the drunk state determination unit 100 . Although the driver recognition unit 110 refers to the driver as the object, it can be targeted to the passenger.

At this time, if there is no passenger, the drunk state determiner 100 or the vehicle controller 300 may be operated. That is, the driver's breathing is sensed to determine the drinking state, and the driving mode is set to limit the driver's driving mode based on the determined breathing state, so that the vehicle V can be controlled.

When the occupant is one, the breathing state of the driver may be detected based on breathing characteristics including the intensity and direction of breathing, and then the breathing state determination unit 100 to the vehicle control unit 300 may be performed.

When the number of passengers is two or more, the driver can perform direct breathing measurement and then perform the drinking state determination unit 100 to the vehicle control unit 300. In this case, it is possible to utilize a seat detection sensor built in the passenger seat to direct breath measurement to the driver. If the passenger measures respiration instead, the passenger's hip may be seated off the seat. When the passenger is seated, even if the respiration is measured, the respiration measurement can be induced in the system without judging the measured respiration as the respiration of the driver.

Also, inducing direct breathing measurement to the driver is a process of measuring the driver's body information in the breath measurement to judge whether the breathing person is a driver or a passenger, and can direct breath measurement. The driver's body information may be previously measured and stored information, which may include pupil information and the like.

That is, when the number of passengers is two or more, it is possible to continuously check the driver's drinking measurement in a shorter pattern (short time interval) even after the driver's direct breathing is detected on the system. In this case, if the measured value of alcohol drinking is unstable, it is possible to induce repetitive direct breath measurement at a predetermined time interval on the system, and automatically switch to the autonomous mode when it is rejected.

As described above, the method of controlling the vehicle when the passenger is present is to measure the respiration of the passenger rather than the driver, or to measure the respiration of the passenger by the passenger so as to prevent the objectivity from being deteriorated in the judgment of the driver's drinking status. For this, the drinking state determination unit 100 may be installed in the driver's seat of the vehicle V to increase objectivity.

On the other hand, if there is a passenger who has not drunk through the passenger drunk state determination unit 400, it is advisable to drive the passenger. At this time, the recommendation method can be done by notifying. If the passenger refuses to drive and the drunk driver is constantly sitting in the driver's seat, the vehicle can be controlled in autonomous mode.

FIG. 6 is a flowchart of an autonomous driving control method for improving user safety according to the first embodiment of the present invention. FIG. 7 is a flowchart illustrating an autonomous driving control method for improving user safety according to a second embodiment of the present invention.

6 and 7, an autonomic driving control method for improving user safety according to an embodiment of the present invention includes a step S100 for determining a drinking state, a step S200 for setting a driving mode, and a step S300 for controlling a vehicle .

At this time, the vehicle V for performing the autonomous driving control method for improving user safety according to the embodiment of the present invention may be a vehicle capable of operating in an operating mode in which the driver directly operates the vehicle or in an autonomous driving mode. In addition to the mode for directly operating the vehicle, the autonomous driving mode is also configured as a possible vehicle, which is a factor for preventing the debate and accident of drinking driving in future vehicles. In this case, the vehicle (V) is intended for the autonomous driving mode to implement the autonomous driving mode, but it can be applied to various smart vehicles that are future cars.

In the drinking state determination step, the drinking state determination unit 100 mounted on the vehicle V may sense the driver's breath to determine the drinking state (S100). This is a step for providing a more objective drinking condition determination result by using the method of determining the drinking state through the respiration of the driver used for the alcohol interception.

At this time, the alcohol status determination step S100 may include a driver recognition step S110, an amount measurement step S130, and an alcohol concentration value measurement step S150.

In the driver recognizing step, the driver recognizing unit 110 detects whether a driver is seated and recognizes a driver who wants to detect breathing (S110). This is a step for sensing breathing when the driver is seated in the vehicle V, that is, when he / she wants to drive. Or if the passenger has a passenger other than the driver in the vehicle V, it is a step for accurately identifying the person who intends to drive. At this time, S110 can be utilized by combining various auxiliary measuring means such as a method of measuring the alcohol by the skin.

Meanwhile, in step S110, the driver's seat is detected by a seat occupancy measuring sensor, and various sensors may be used depending on the user's setting, such as a pressure-reducing sensor, which can be installed inside the vehicle.

In the step of measuring the amount of exhalation, the amount of exhalation of the driver recognized by the exhale amount measuring unit 130 may be measured (S130). This is a step for objective measurement of blood alcohol concentration using exhalation.

In the step of measuring the alcohol concentration value, the alcohol concentration value included in the driver's exhalation measured by the alcohol concentration value measuring unit 150 may be measured (S150). This is a step for measuring the alcohol concentration value included in the exhalation and ascertaining the driver's drinking status as a numerical value.

The driving mode setting step may be set to a driving mode for limiting the driving mode of the driver based on the drinking state determined by the driving mode setting unit 200 (S200). This can be said to be a step for preventing the debate and accident of drunk driving through the control of the vehicle itself, that is, the autonomous driving control.

S200 can be performed in the self-driving mode setting step S210 or the performance mode setting step S230 according to the determined drinking status.

The autonomous mode setting step may set the driving mode of the vehicle V to the autonomous driving mode when the alcohol concentration value measured by the autonomous driving mode setting unit 210 is equal to or greater than a preset concentration value (S210) .

The execution mode setting step may set the running mode of the vehicle V to the execution mode when the alcohol concentration value measured by the execution mode setting unit 230 is smaller than a predetermined concentration value at step S230.

S210 and S230 may be a step for providing an optimal driving mode by comparing the numerical drunk driver's drinking state with a predetermined comparison target value.

On the other hand, when the vehicle V is controlled in the run mode, the running mode of the vehicle V can be changed or maintained by repeating S100. This is a feature that allows you to maintain safety until the end of the journey through continuous drinking measurement. Particularly, the repetition of step S100 is a feature for preventing the driver from performing drunken driving after drinking the driving mode among the modes in which the driver directly operates the vehicle.

Accordingly, in the vehicle control step, the vehicle V can be controlled according to the driving mode set in the vehicle control unit 300 (S300).

If the control of the vehicle V is not performed even after a predetermined time has elapsed, S300 may change the running mode of the vehicle V to the autonomous running mode so as to control the vehicle to move to the address preset by the user. This is a feature for letting the driver return home through autonomous driving when it is determined that the driver is in the dull state when there is no adjustment for the vehicle V for a predetermined time.

At this time, the control of the vehicle V may be referred to as a direct control of the driver including an engine button, a handle, and a brake operation.

Meanwhile, the autonomic driving control method for improving user safety according to the embodiment of the present invention further includes a passenger drinking state determination step in addition to the drinking state determination step S100, the driving mode setting step S200, and the vehicle control step S300 can do.

In the passenger drunk state determination step, the passenger drunk state determination unit 400 can determine the drunk state of the passenger traveling on the vehicle V other than the driver. This is a step that takes into consideration the fact that the person boarding the vehicle V is not limited to one driver. At this time, the step of determining the passenger's drinking state can be performed in the same manner as the driver recognition step S110, the amount of exhalation measurement step S130, and the alcohol concentration value measurement step S150 included in the drinking state determination step S100. Although S110 refers to the driver as the object, it is possible to target the passenger.

If there is no passenger at this time, S100 to S300 can be performed. That is, the driver's breathing is sensed to determine a drinking state, and the driving mode is set to limit the driver's mode of operation based on the determined breathing state, so that the vehicle V can be controlled.

If the passenger has one passenger, breathing of the actual driver may be detected based on breathing characteristics including the intensity and direction of breathing, and then steps S100 to S300 may be performed.

When the number of passengers is two or more, it is possible to conduct the breath measurement directly to the driver, and then perform steps S100 to S300. In this case, it is possible to utilize a seat detection sensor built in the passenger seat to direct breath measurement to the driver. If the passenger measures respiration instead, the passenger's hip may be seated off the seat. When the passenger is seated, even if the respiration is measured, the respiration measurement can be induced in the system without judging the measured respiration as the respiration of the driver.

Also, inducing direct breathing measurement to the driver is a process of measuring the driver's body information in the breath measurement to judge whether the breathing person is a driver or a passenger, and can direct breath measurement. The driver's body information may be previously measured and stored information, which may include pupil information and the like.

That is, when the number of passengers is two or more, it is possible to continuously check the driver's drinking measurement in a shorter pattern (short time interval) even after the driver's direct breathing is detected on the system. In this case, if the measured value of alcohol drinking is unstable, it is possible to induce repetitive direct breath measurement at a predetermined time interval on the system, and automatically switch to the autonomous mode when it is rejected.

As described above, the method of controlling the vehicle when the passenger is present is to measure the respiration of the passenger rather than the driver, or to measure the respiration of the passenger by the passenger so as to prevent the objectivity from being deteriorated in the judgment of the driver's drinking status. For this purpose, in order to perform S100, the drinking state determination unit 100 is installed in the driver's seat of the vehicle V, thereby increasing the objectivity of the driver in determining the drinking state.

On the other hand, if there is a passenger who has not drunk through the step of determining the state of drunk driving, it is advisable to drive the passenger. At this time, the recommendation method can be done by notifying. If the passenger refuses to drive and the drunk driver is constantly sitting in the driver's seat, the vehicle can be controlled in autonomous mode.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated by those skilled in the art that numerous changes and modifications may be made without departing from the invention.
