Particularly, in the present invention, it is desirable to understand that the vehicle driving control is such that a person aboard a vehicle other than a car is prevented from being trapped in the vehicle, moved or prevented from being operated.

FIG. 3 is an explanatory view of a scenario illustrating a video recording and a vehicle theft prevention according to the theft event of the present invention.

The following proximity image data, the theft attempt image data, the theft end image data, and the escape image data are defined to help understand the explanation. These image data are used to detect camera images captured before, after, it means.

When a thief steals valuables in the inside of a car as shown in FIG. 3, there may be a case in which a thief enters the inside of a car (not shown in the drawing) and tries to escape by driving the car .

The thief strolled around the vehicle while checking to see if there were any people around him, and after he approached the vehicle, he attempted to steal the vehicle window by breaking the vehicle window or by opening the door with a duplicate vehicle key. They steal valuables or start a car with a replica car key to try to steal the car. Afterwards, the thief steals valuables and escapes or escapes if the vehicle fails to operate.

In the present invention, If the proximity of the vehicle is detected, the camera may be booted and the image may be continuously photographed.

Then, the image data (that is, the proximity image data) being photographed by the camera is temporarily stored.

If aft robbery event such as vehicle shock caused by a thief, vehicle body inclination or movement change, door opening, window breakage, or locks the vehicle with a smart key and the vehicle is unlocked with a physical key is sensed, The image data (that is, the theft attempted image data), which is continuously photographed by the camera and temporarily stored, is stored as write data.

When the theft attempt event is sensed, the mobile communication terminal periodically transmits a character or camera shot image (that is, stolen trial image data temporarily stored) to a smartphone or the like through a wireless communication unit to notify the occurrence of a vehicle stolen event.

In addition, when the theft attempt event is sensed, a warning broadcast is periodically transmitted to the thief through a speaker.

In addition, when the theft attempt event is sensed, the vehicle driving control such as prohibition of starting is performed through a driving locking unit (38).

Then, when the theft end event is sensed through various sensors, the image data continuously captured by the camera for a predetermined time after the occurrence of the theft end event and the temporary stored image data (i.e., theft end and escape image data) are stored by writing , And after the theft of the vehicle, the thief's theft end image and escape image are secured. Here, the theft end event sensing may be a case where a predetermined time has elapsed from the time when the last vehicle impact occurred, a door that has been opened is closed, a physical vehicle key is taken out, a thief has entered the vehicle, .

Hereinafter, an event image recording and recording apparatus and method of the present invention, a vehicle theft prevention system using the same, and a method thereof will be described in detail with reference to FIG.

FIG. 4 is a flowchart illustrating an event video recording method and an anti-theft method according to an embodiment of the present invention.

First, the control unit 17 monitors the driving state of the vehicle through interlocking with the vehicle system, that is, monitors whether the vehicle is in the vehicle parking state, the vehicle parking state is maintained, and the vehicle parking state is released. In the present invention, the process of determining the driving state of the vehicle is not an essential component, and it may be started from the following process without performing the process of determining the driving state of the vehicle. That is, the present invention is preferably performed in the vehicle parking state, and can be performed even when the vehicle is in a running state. On the other hand, there are various methods for determining the driving state of the vehicle, but any method may be used in the present invention. For example, in the case of using GPS, it is determined that the vehicle is parked when there is a change in the current position with the lapse of time, and the vehicle is parked if there is no change in the current position even after a predetermined time elapses. As another example, if the vehicle battery power is applied, it is determined that the vehicle is parked. If the vehicle battery power supply is blocked, the vehicle is parked. As another example, the case where the vehicle speed becomes zero (zero) using the vehicle cluster information or the event sensing information using the acceleration sensing function of the motion sensor is determined as the vehicle parking state. As another example, the case where the start switch-off is continued for a predetermined time is determined as the vehicle parking state, the case where there is no change in the cluster traveling distance is determined as the vehicle parking state, , The case where the wheel sensor does not change the wheel rotation is judged to be the vehicle parking state, or the case where the camera photographing image frames are not compared is judged as the vehicle parking state. As another example, a parking mode menu may be provided in the event video recording apparatus so that the user can selectively set the parking mode menu. In addition, in the present invention, it is sufficient to grasp the parking state without vehicle movement in determining the driving state of the vehicle, so that accurate positioning is not necessary. That is, although it is possible to use GPS, since it is only necessary to determine whether or not the position is changed, the parking status of the vehicle can be determined by an impact sensor, an acceleration sensor, a geomagnetism sensor, a gyroscope, a distance sensor and a proximity sensor.

If the driving state of the vehicle is determined as the vehicle parking state, The door sensor 33, the window sensor 34, the vehicle key sensor 35, and the sensor 35. The control unit 17 controls the operation of the door sensor 33, the proximity sensor 31, the impact sensor 32, the door sensor 33, The tire air pressure sensor 36, and the like are operated so that theft detection event sensing monitoring is operated (402). Here, since there is a problem of vehicle battery discharge in the vehicle parking state, it is preferable that the sensing operation of various sensors is performed in a predetermined time period in order to minimize power consumption. In addition, it is preferable not to immediately drive the camera 11 when initializing the event video recording apparatus. Here, it is desirable to understand that the camera is not driven (termination of driving) as a sleep mode, a state in which the camera is not initialized, or a state in which no power is supplied.

When the proximity sensor 31 senses proximity of the vehicle, the control unit 17 drives the camera 11 through a boot process to continuously capture the image (404).

Then, the control unit 17 temporarily stores the image data photographed by the camera 11 (i.e., the proximity image data before the theft occurrence event) in the temporary storage unit 12 by buffering (405). Here, the proximity image data before the stolen event is temporarily stored, which is not the thief since the proximity sensing is performed by the passerby passing around the vehicle, so that the image data is not permanently stored in the nonvolatile storage medium 13 . Since the nonvolatile storage medium 13 such as a flash memory has a limited number of data writing operations, it is possible to prevent shortening of the life of the flash memory due to unnecessary image storage instead of an event image.

Subsequently, within a predetermined time, a vehicle striking such as a vehicle shock, vehicle body inclination or movement change, door opening, window breakage, or a smart key is used to lock the vehicle through the various sensors 31 to 36 When the event is sensed 406, the control unit 17 stores the proximity image data temporarily stored in the temporary storage unit 12 and the image data continuously captured by the camera 11 and stored temporarily The data is stored in the nonvolatile storage medium 13 by writing (407).

If the theft attempt event is sensed 406, the control unit 17 periodically transmits a character or camera photographed image (i.e., stolen trial image data temporarily stored) to the mobile phone through a wireless communication unit 15 And notifies the occurrence of the vehicle stolen event (408).

If the theft attempt event is sensed 406, the control unit 17 periodically transmits a warning broadcast to the thief through the speaker 37 (409).

If the theft attempt event is sensed 406, the control unit 17 performs driving control such as prohibition of starting through a driving lock unit 38 (410). At this time, the vehicle drive control may be prohibited such as start prohibition, steering wheel lock, foot (side or hand) brake, vehicle battery power cutoff, gas supply shutoff, driver seat folding, side mirror folding, gear shift locking, have. Particularly, in the present invention, it is desirable to understand that the vehicle driving control is such that a person aboard a vehicle other than a car is prevented from being trapped in the vehicle, moved or prevented from being operated.

Then, when a theft end event is sensed through the various sensors 31 to 36 (step 411), the controller 17 continuously records the image data temporarily stored in the camera for a predetermined time from the time of the theft end event sensing, (I.e., theft end and escape image data) are also stored in the nonvolatile storage medium 13 by writing data (412). Here, the theft end event sensing may be a case where a predetermined time elapses from the last vehicle shock occurrence time, a door that has been opened is closed, a physical vehicle key is taken out, a thief who has entered the vehicle comes out and a tire air pressure change occurs . By doing so, after the theft of the vehicle, the thief is also able to obtain the image of the end of the theft and the escape image.

After storing the image data after the stolen end event, the controller 17 stops driving the camera 11 (413). Thereafter, the control unit 17 carries out a vehicle proximity sensing and aft detection event sensing monitoring process. At this time, the process of ending the storage of the image data is performed by writing all the image data temporarily stored in the temporary storage unit 12 to the nonvolatile storage medium 13 after a predetermined time from the point of time of the theft end event sensing The data writing can be terminated after a predetermined time from the point of time when the theft end event sensing is performed regardless of the image data temporarily stored in the temporary storage unit 12. [

On the other hand, when the proximity of the vehicle is sensed and an event such as a vehicle shock is not sensed within a predetermined time, the control unit 17 drives the camera 11 to be shut down. Thereafter, the control unit 17 carries out a vehicle proximity sensing and aft detection event sensing monitoring process. In addition, when the proximity of the vehicle is sensed and an event such as a vehicle impact is not sensed within a predetermined time, the control unit 17 may discard or retain the image data stored in the temporary storage unit 12.

Even if the proximity of the vehicle is not sensed, the control unit 17 may drive the camera 11 to store the acquired image data in the nonvolatile storage medium 13 when the event such as a vehicle shock is detected.

Next, various extended embodiments of the present invention will be described.

In the present invention, when photographing a thief's impression, behavior, etc. with the camera 11, it is possible to photograph the image in various ways in order to increase the stolen image recognition rate. For example, it is possible to take an image of the direction of the vehicle interior with the camera, use an approach-view camera shooting method, or photograph the image while rotating the camera.

Meanwhile, in the present invention, a camera photographed image is stored according to a robbery attempt event such as proximity sensing and / or shock sensing. In storing an image before / after an event, all image frames are not stored, Only the image frame containing the object can be stored in the nonvolatile storage medium. As another example, only a predetermined area including an object in an image frame, a vehicle, and the like may be stored in the nonvolatile storage medium, not the scene itself of the image frame including the object. By doing so, it is possible to reduce the number of data writing times of the nonvolatile storage medium and to reduce the waste of the storage capacity, and there is an advantage that real time processing is ensured and unnecessary signal processing is not performed.

In the case where multiple event sensors and cameras such as a proximity sensor and a shock sensor are mounted, in the present invention, a sensor having a sensing operation using sensor mounting position / direction information and camera mounting position / direction information and a camera corresponding to the sensor Only captured images can be stored in a nonvolatile storage medium.

Meanwhile, according to the present invention, it is possible to set an object as a distance change approaching a vehicle or an event image recording apparatus under a proximity sensing condition. If the proximity sensing distance is set farther, old image data before an event can be secured Pull the previous video point forward].

In the present invention, it is preferable that the proximity sensor is implemented by an ultrasonic method or the like. However, it is preferable that the distance between the camera and the object is measured using at least one camera installed in the vehicle, It is possible. As another example, an infrared type proximity sensor may be used in a dark environment.

On the other hand, in the case of using an ultrasonic proximity sensor, an error in proximity sensing operation may occur due to ambient noise during driving and signal interference of an ultrasonic sensor of another vehicle. Therefore, in the present invention, a magnetic identification code is inserted in the ultrasonic wave of the proximity sensor and transmitted, or a separate infrared sensor is further installed, so that only the data when the sensing result of the ultrasonic sensor matches the sensing result of the infrared sensor is used as the correct proximity sensing data It is possible.

On the other hand, when the event sensor such as the proximity sensor fails, the operation of the event image recording apparatus may not be performed properly. In this case, in the present invention, when the failure of the sensor is determined, it is preferable to switch to the normal continuous image shooting recording mode without performing the above-described event image shooting recording process and to store the image shot by the camera in the nonvolatile storage medium. Of course, when the sensor is determined to be faulty, the user is informed to receive the sensor replacement / repair, and the user can be informed that the normal image capture recording mode is performed until the sensor operates normally.
