Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a locking device,

The present invention relates to an apparatus and method for controlling a locking state of an automobile door, and more particularly, to an apparatus and method for controlling a locking state of an automobile door, The present invention relates to an automatic door lock state control device and a control method for automatically controlling a lock state of an automotive door.

Due to the development of the automobile industry and the improvement of the standard of living, a number of advanced technologies have been applied to automobiles in order to improve the safety of the automobile and the convenience of the driver in proportion to the surge of the automobile supply. Hereinafter, the convenience of such advanced technology will be briefly described.

AVM

(Hereinafter referred to as " AVM "), which allows a driver to easily visually confirm the surrounding environment of a vehicle by photographing and displaying the surrounding environment of the vehicle.

The vehicle surroundings image display system captures the surrounding environment through cameras installed on the front, rear, left, and right sides of the vehicle, corrects the overlapped areas to look natural based on the captured images, (See Fig. 1).

Accordingly, the driver can quickly and conveniently recognize the surroundings of the vehicle through the screen, and can easily drive and park the vehicle comfortably without looking at the side mirrors or the rearview mirror.

DSM

Accidents that cause the greatest damage during a car accident occur during driving, and most of them are usually caused by drowsiness driving, drunken driving, and dispersion of attention.

As a method for preventing such accidents in advance, in the past, the driver himself or herself has been forced to rely on self-awareness and carefulness. However, in recent years, technically, the driver's condition is monitored and the driver is warned , And a typical example thereof is a Driven-State Monitoring Device (hereinafter referred to as " DSM ").

The driver condition monitoring system monitors the driver 's face and determines the state similar to drowsiness by an algorithm that prioritizes the characteristics of the eye blinking, that is, the blinking frequency and the number of times, and assigns weight to elements close to drowsiness. Also, the detection of the state of dispersion of the state of attention is based on the recognition result of the face direction and the eye state, and a warning is given when the user does not look forward for a designated time (refer to FIG. 2).

Therefore, when the driver neglects or looks forward, the driver will not make an alarm or release the lane through his / her own control.

PAS

In the past, the driver used the side mirror or the back mirror mounted on the vehicle to move the vehicle while checking the rear or side obstacles. However, in the rear corner of the vehicle, there is a blind spot that the driver can not recognize, and even if the driver recognizes the obstacle, the distance between the vehicle and the obstacle can not be calculated It may come in contact with obstacles.

In order to solve such a problem, a sensor is mounted on the rear and front bumper of a vehicle, and a warning signal indicating that the distance between the object to be sensed by the sensor and the vehicle is close to each other A parking assist system (hereinafter referred to as " PAS ") was introduced (see Fig. 3).

In this device, an ultrasonic sensor or the like is installed on a bumper or the like to measure a distance to an object near the object, and the measured value is transmitted to the ECU, and the ECU sends an alarm to the driver. Such a PAS sensor is usually measured to a distance of about 2.5 meters, and it is helpful to recognize the distances from the obstacle when parking by changing the state of the alarm at different distances.

BSD

Generally, a side mirror of a vehicle is used as a basic component of a vehicle that secures left and right rear vision of a vehicle. The side mirrors of a car have a blind spot of the driver's visual observation and a certain angle by the B-pollar. The blind spot of the car is generally defined as a 13 ° ~ 45 ° area with respect to the side of the car.

Therefore, when the trailing vehicle enters the blind spot, the leading vehicle may not recognize the trailing vehicle. In this case, there is a problem that the leading vehicle tries to change the lane in the direction of the trailing vehicle.

Blind Spot Detection (hereinafter referred to as "BSD") is a system in which a radar is mounted on the left and right sides of a rear bumper of a vehicle to detect a trailing vehicle approaching the side of the vehicle, (See FIG. 4), or may be displayed on the head-up display as an advanced specification.

However, the above-mentioned various convenience specifications faithfully perform only the original function pursued by the apparatus or system, and it is very rare to use new functions together with other convenience functions.

In other words, the AVM can visually check the situation outside the car and supports the parking. The PAS recognizes the distance from the surroundings to support the front / rear parking, the DSM prevents the driver from drowsy driving, It is an essential function of detecting an automobile within a certain distance at the time of driving and notifying a driver of the vehicle. Considering that these convenience specifications require relatively expensive equipment, it can be said that it provides only a very simple function.

FIG. 5 is a block diagram schematically showing the configuration of an apparatus for controlling a locked state of an automotive door according to an embodiment of the present invention. As shown in FIG. 5, An output unit 40, a passenger recognition and storage device 50, and a control unit 60. [

The surrounding situation sensing unit 30 is a unit for sensing an object approaching the automobile and detects various peripheral conditions input from various sensors 10 and a camera 20 mounted on the automobile.

The ambient condition sensing unit 30 senses an object approaching from the front or rear of the automobile, for example, a person or another automobile, with the sensor 10 of the PAS system mounted on the vehicle, To the control unit (60). The sensor of such a PAS system can detect objects approaching within 1 to 1.5 meters from automobile.

Alternatively, the peripheral situation sensing unit 30 is configured to sense an object approaching from the rear of the vehicle as a sensor of a BSD system mounted on the vehicle, and transmit the sensing signal to the control unit 60. [ The sensors in the BSD system can detect objects approaching within 3 meters of the vehicle.

Such a sensor may be one of an ultrasonic sensor, an infrared sensor or a radar, and may be different depending on the type of the mounted convenience. However, any sensor may be used as long as it can recognize an object approaching the automobile in basic functions.

The passenger recognition and storage unit 50, which is one of the characteristic components of the present invention, performs a function of recognizing and storing the appearance of a passenger who has boarded the automobile. The passenger recognizing and storing section 50 can use, for example, a DSM apparatus mounted on an automobile.

That is, since the DSM device is a convenience specification configured to recognize the characteristic of the blinking of the eyes on the driver's face in order to monitor the driver's face originally, the face recognition camera can recognize each person's face . Therefore, by recognizing not only the driver but also the appearance of the passenger, the appearance of a person who has boarded the vehicle is recognized and stored in the storage device. If the object to be accessed to the vehicle is a person later, So that people can be distinguished.

The output unit 40 may include a video output unit and an audio output unit, and the video output unit may be an indoor camera installed in a car, for example, a camera used for an AVM, a DSM, or a black box . The audio output unit can use ordinary car audio.

The control unit 60 controls the above-described constituent units to control the lock state of the vehicle door according to the present invention, and a control method thereof will be described with reference to FIG.

First, as described above, the passenger recognition and storage device 50 recognizes and stores the appearance of a passenger who has boarded the vehicle, for example, using the DSM system (S101). Of course, all passengers may be able to recognize and store their appearance, and selectively recognize and store only those who need it.

When the driver is in the vehicle and the vehicle is in the IGN or START state when the passenger recognizes and stores the appearance and thus the passenger leaves the vehicle and returns from the vehicle, Is sensed by the sensors 10 of the vehicle 10, the approach of the passenger approaching the vehicle is also detected (S102).

In this way, when the vehicle or a person approaches the vehicle within a predetermined distance, for example, within 1.5 meters, the surrounding situation sensing unit 30 senses it and transmits a signal to the control unit 60. [

Upon receipt of the detection signal from the surrounding situation sensing unit 30, the control unit 60 confirms the current door lock state of the vehicle (S103).

If the door of the automobile is locked, the appearance of the passenger whose approach is detected by the surrounding situation monitoring unit 30 is recognized by the AVM camera 20 installed outside the automobile, Lt; / RTI >

The control unit 60 receiving the signal compares the appearance of the approaching person coming from the surrounding situation sensing unit 30 with the appearance of the passenger recognized and stored by the passenger recognition and storage unit 50 in step S104. Then, an alarm sound is issued through the audio output unit (S106).

At this time, if the door is not locked, the controller 60 locks the door once (S105). Then, an alarm sound is issued through the audio output unit as described above (S106).

The reason why the approaching person confirms that the passenger is the passenger who has boarded the automobile is that if the passenger leaves the automobile and is scheduled to be re-boarded in the future, if the door is already locked, This is to enable the driver in the car to have an emotional experience in terms of allowing the driver to open the door by notifying the driver in advance that the driver of the vehicle is approaching by the vehicle.

Also, for example, if a driver or other passenger who has not been aware of the approach from another vehicle or someone else from behind the vehicle is attempting to get off, there is a possibility of being exposed to a dangerous situation.

Accordingly, when there is an object approaching by an automobile, the control unit 60 locks the door at one time (S105) and emits an alarm (S106), thereby notifying passengers attempting to get off, . In order to achieve this purpose, the locking state of the door is maintained for at least 5 seconds to 10 seconds. Thereafter, when the passenger including the driver attempts to release the door again, recognizing that the intention is to intentionally release the locked state of the door, the locked state of the door is released (S108), and if not, The locked state is maintained (S109).

The foregoing detailed description should not be construed in all aspects 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.
