Description

Anti-theft device for vehicle

Technical Field

The invention belongs to the technical field of anti-theft devices of vehicles, and particularly relates to a vehicle anti-theft device.

Background

In general, a vehicle is provided with a plurality of function operation units, and a switch assembly is provided at a plurality of places inside the vehicle in order to activate the function operation units. The plurality of function operation units herein means a concept including all devices operated by predetermined electric signals generated by the above-described switch unit, such as an audio device, an air conditioner, and a navigation device of a broadcasting system installed in a vehicle.

With the pursuit of advanced and convenience of vehicles, there are more functional operations that require additional execution of new functions, and there is an inevitable need to additionally install a switch assembly for starting the functions.

However, the additional installation of the switch module in the vehicle requires a complicated design, and the degree of freedom in the design of the vehicle is greatly impaired, and there is a problem in that the design of the wiring arrangement for electrically energizing between the switch module and the control unit (BCU) for controlling the switch module is complicated.

Recently, a switch system has been developed which installs a plurality of motion detection sensors in a vehicle for detecting movement of a user without the user directly contacting a switch assembly, and when the user covers each of the installed motion detection sensors for a predetermined period of time, a corresponding function operation unit is activated. However, such a switching system has a problem in that not only the movement detection sensors corresponding to the number of each functional operation unit are provided, but also the above-described wiring layout and the like are still in existence for energizing each movement detection sensor.

In addition, in recent vehicles, when the vehicle is not in use (i.e., an unmanned vehicle in which passengers including a driver are not at all in the vehicle cabin), in order to identify a person who has forced intrusion into the vehicle cabin, a movement detection sensor that detects the vehicle cabin is provided, and the detected vehicle cabin interior is immediately subjected to mobile communication to the vehicle owner, thereby preventing theft of the vehicle. In particular, in the motion detection sensor for detecting the motion between vehicles, in order to secure image information of an intruder who intrudes into a workshop, a camera is additionally provided to secure a decisive cue that an intruder or a vehicle can be arrested after being stolen.

In the vehicle intrusion detection device according to the related art, however, since a separate camera for identifying an intruder must be provided, the cost increases. Meanwhile, when the vehicle interior is darkened, there is still a problem in that it is difficult to provide a decisive cue even if an image or images of an intruder are ensured.

Further, the control unit compares an image obtained by a camera in the gesture detection unit with a specific gesture image as a reference to apply an electric signal for operating a predetermined function operation unit when an engine of the operation vehicle is started, and the specific gesture image generates a corresponding electric signal according to an input pattern algorithm to control different function operation units;

the operating state of the camera is selectively controlled when the vehicle engine is not started.

While the control unit continuously transmits a warning sound through at least one of an alarm or a horn mounted on the vehicle to control the intrusion intention of the intruder.

Further, when the vehicle engine is not started and locks the side door and the vehicle interior is completely free of passengers, the vehicle interior is entirely scanned by using the camera of the gesture detection unit for photographing to ensure a basic image of whether or not the intrusion object detected later intrudes into the vehicle interior;

meanwhile, the control unit filters the internal images of the vehicle shot according to the set times at set time intervals to distinguish the fixed object inside the vehicle from the dynamic object outside the vehicle.

Further, the vehicle intrusion detection system further comprises a black box camera, wherein after the motion detection unit judges that the vehicle intrusion is detected, if the control unit does not detect that the vehicle inside moves further, the black box camera is started, the escape direction information of an intruder escaping after the vehicle intrusion is recorded into a video, and meanwhile, the information of other intruders is collected.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1 and 2, an embodiment of the present invention provides a vehicle anti-theft device, including:

When the gesture detection unit is located at the front end of the center console (when the gesture detection unit is used for a switch described later), not only a specific gesture of a passenger (including a driver) can be easily detected, but also when the gesture detection unit is used for photographing described later, not only all seats inside the vehicle but also the outside of the vehicle (outside of the window) can be recognized using image recognition software, so that the inside of the vehicle can be accurately intruded. That is, since an intruder can break a window at the outside without directly invading the inside of the vehicle and then put a hand or the like into the inside of the vehicle to steal an important item stored in the inside of the vehicle, it is preferable to be disposed at a position capable of recognizing the outside of the vehicle by the gesture detection unit.

As shown in fig. 3, the gesture detection unit is composed of a camera provided in the vehicle interior, the camera including a lens 41 that obtains a predetermined image, an infrared LED43 provided in a ring shape along an edge of the lens 41 and emitting a predetermined infrared ray, and an infrared heat generating body that enters into a radiation angle of the infrared LED43 is photographed through the lens 41.

The infrared LED43 is configured to include a light emitting portion that transmits infrared light at a predetermined illuminance. Here, the predetermined illuminance may be understood as the brightness of light, but may be understood as the intensity of infrared rays emitted from the light emitting portion, as the case may be.

The lens 41 is configured to collect an image of an object to be photographed and photographed by an image sensor, not shown, and then image-processed by an image processing board, and functions as a converging unit that again collects infrared rays emitted from the above-described light emitting unit. The camera will shoot the infrared heater through the lens 41 into the emission angle of the infrared LED 43.

The gesture detection unit as described above may be installed in a built-in form in a vehicle for detecting a specific gesture of a driver or a passenger on the vehicle, and may be used for photographing the interior of the vehicle. Such gesture detection units may be manufactured separately and arbitrarily fixed in the vehicle. That is, the gesture detection unit may be configured such that the rotatable user manually adjusts the detection angle.

A preferred embodiment of the apparatus for preventing intrusion of a vehicle according to the present invention includes: generating and applying a predetermined electric signal for starting a predetermined function operation unit provided in the vehicle at the time of starting the vehicle engine based on the movement detected by the gesture detection unit; and a control unit that determines whether the vehicle intrudes into the vehicle interior and alerts the owner when the vehicle engine is not started.

Here, the control unit may be a BCM that controls the entire vehicle body, or may be an intrusion prevention device-specific control unit that controls only the structure directly related to the vehicle intrusion prevention device according to the present invention.

The motion detection unit may be at least one of a G sensor for detecting a tilt of the vehicle and an ultrasonic sensor that transmits ultrasonic waves inside the vehicle and receives the ultrasonic waves. Of course, a combination of both the G sensor and the ultrasonic sensor may be provided in the vehicle to detect movement in the vehicle.

The motion detection unit may indirectly identify an object invading the vehicle interior by using a G sensor that detects the inclination of the vehicle, and may detect by directly identifying a frequency change of the ultrasonic wave irradiated to the vehicle interior. For example, even if the G sensor detects a change in inclination of the vehicle body caused by an external factor such as strong cyclone, the vehicle interior may not move, in which case, of course, more accurate detection can be performed by the ultrasonic sensor.

In a preferred embodiment of the apparatus for preventing intrusion of a vehicle according to the present invention constructed as described above, the control unit may apply an electric signal for operating a portion of the plurality of functional operation units mounted in the vehicle by comparing an image obtained by the camera with a specific gesture image when the vehicle engine is operated, and the control unit may selectively operate the camera when the vehicle engine is operated.

In particular, according to a preferred embodiment of the vehicle intrusion prevention device of the present invention, although not shown, it may further include an analysis module for analyzing the image detected by the gesture detection unit in a pattern and transmitting a predetermined electric signal according to the analyzed pattern to operate the plurality of function operation units.

The analysis module may be an image processing PC capable of processing the image detected by the gesture detection unit, or may be a PC for a self-service machine.

The analysis module is mainly used for comparing the shot and stored infrared images with the input mode algorithm through the perception of the gesture detection unit and generating an electric signal corresponding to the result value of the matching algorithm. The generated electric signal performs a function as an operation ON (ON) or an operation OFF (OFF) signal of the corresponding function operation unit.

For example, when an image (hereinafter, for convenience of explanation, simply referred to as a "first image") of a specific passenger (including a driver) in a specific region in a vehicle is captured by a gesture sensing unit and then developed, an electric signal (hereinafter, for convenience of explanation, simply referred to as a "first signal") for turning ON the operation of one of the functional operation units is generated by a pattern algorithm corresponding to the captured first image, and when another image (hereinafter, for convenience of explanation, simply referred to as a "second signal") of the specific passenger in a case of developed finger is generated by the specific passenger, it is assumed that an electric signal (hereinafter, for convenience of explanation, simply referred to as a "second image") for turning ON the operation of one of the functional operation units is generated by a pattern algorithm corresponding to the captured first image, and when an electric signal (hereinafter, for convenience of explanation, simply referred to as a "second signal") for turning OFF one of the functional operation units is generated, the analysis module applies the first signal to the first image by using the inputted pattern algorithm and controls the second signal to be applied by the inputted pattern algorithm.

As described above, the inputted pattern algorithm may be configured to pattern an image of a hand of a specific passenger to generate a corresponding electric signal, and among the plurality of functional operation units, if a signal different from the specific functional operation unit to be switched can be generated, as long as the limiting condition of the detection object emitting infrared rays is satisfied, even an image conforming to the present invention, and in order not to cause confusion in controlling the operation of each functional operation unit, various variables such as the degree of finger bending, the kind of finger spread, and the like may be considered.

Here, the plurality of functional operation units are all applicable to concepts such as an acoustic device including a radio, an air conditioner capable of adjusting the temperature in the vehicle, and a navigation device linked to a GPS, as long as the functional units are mounted on the vehicle, but are not directly related to the running of the vehicle, and are intended to be convenient for the user.

Therefore, in a preferred embodiment of the vehicle intrusion prevention device according to the present invention, the gesture detection unit may be used to detect a specific gesture (hereinafter, referred to as "switch use") of a passenger (including a driver) as a precondition for approval of operation signals of various function operation units of the vehicle at the time of starting of the vehicle engine, or may be used to capture and photograph an intruded object (including a third intruder) intruded into the vehicle interior at the time of not starting the vehicle engine, as will be described later.

More specifically, when the engine of the vehicle is not started and locks the side door mounted on the vehicle, the control unit first photographs and analyzes the number of times inside the vehicle at set time intervals using the camera of the gesture detection unit (in order to secure a more accurate basic image, it is preferable to set the photographing time using the camera to 10 minutes but photograph 60 times within 10 minutes), and when the movement of the inside of the vehicle is detected by the movement detection unit, photographs the inside of the vehicle using the camera of the gesture detection unit.

Here, the vehicle engine not being started refers to a state in which the vehicle engine is turned OFF (OFF) after being started for running, and further, a switching use for preventing a vehicle safety accident is not required during running, and therefore, the camera of the gesture sensing portion is changed to a precondition for the shooting use.

In particular, when the vehicle engine is not started and the side door is locked, there is no passenger at all in the vehicle interior, and therefore, the vehicle interior is scanned entirely by using the camera of the gesture detection unit for photographing to ensure a basic image of whether or not the intrusion object detected later intrudes into the vehicle interior.

By analyzing the basic image obtained as described above, it is determined whether or not a movable object having repeatability by external or internal factors exists inside the vehicle, and whether or not a movable object having non-repeatability exists, and then intrusion of an intruded object photographed by a camera of the gesture detection unit can be compared.

That is, the control unit filters the internal images of the vehicle photographed at set times at set time intervals to distinguish a fixed object inside the vehicle from a dynamic object outside the vehicle, thereby generating an important algorithm for judging intrusion in the future.

At this time, the control unit may assume various illuminances of the infrared LEDs of the gesture detection unit, shoot and store in the vehicle interior, and then analyze through the stored images under the various illuminances to achieve more accurate detection of the intrusion object.

As described above, the control unit photographs the set number of times at set time intervals by the gesture detection unit, and if no movement is found in the vehicle, the control unit first performs operation control in the slide mode in which the operation of the gesture detection unit is stopped.

In addition, when the detection value detected by the motion detection unit is determined to be an intrusion to the vehicle, the control unit may ensure a definitive clue for the following of the intruder by operating the camera of the gesture detection unit to photograph the intruder object.

At this time, when the intruded object photographed by the camera is determined as a human, the control unit may capture the face of the intruder and improve the image quality and immediately transmit it to the portable terminal of the owner.

The mobile terminal may be a mobile phone equipped with a display unit capable of displaying an image, or a mobile phone capable of transmitting and receiving data using broadband mobile communication, and is not limited to a mobile phone, and any mobile terminal is included in the scope of the mobile terminal of the present invention.

When the gesture detection unit is used for photographing, as shown in fig. 2, all seats disposed at the rear of the vehicle interior may be detected by being disposed at the front end of the center console, and a photographed image may be obtained by an intruder shielded in the vehicle interior by a particular band or more of the radiation infrared rays.

That is, the gesture detection unit that switches to the slide mode switches to the Wake up mode (Wake up mode) that is ON when it is determined that the intrusion of the intrusion object is detected by the motion detection unit detecting the motion of the vehicle interior, and continuously photographs the vehicle interior until no movement of the vehicle interior is detected by the motion detection unit.

On the other hand, a preferred embodiment of the vehicle intrusion prevention device according to the present invention may include at least one black box camera for photographing at least one of the front or rear of the vehicle.

After the control unit determines that the vehicle is intruded, if the movement detection unit does not detect that the vehicle is moving further, the control unit starts the black box camera, records information on the direction of escape of an intruder who escapes after the vehicle is intruded into a video, and can collect information of other intruders.

Further, when it is determined by the movement detection unit that the value is intrusion into the vehicle interior, the control unit may control the intrusion intention of the intruder by continuously transmitting a warning sound through at least one of an alarm or a horn mounted on the vehicle, thereby fundamentally blocking the intrusion intention of the intruder.

The operation of the vehicle intrusion prevention device according to the present invention constructed as described above is briefly described below with reference to the accompanying drawings.

As shown in fig. 4, the gesture detection unit is used as a switch when the vehicle engine is started, i.e., while the vehicle is running.

When the vehicle engine is not started, that is, when the vehicle is parked in the parking lot for a long time without a passenger sitting therein, the gesture sensing unit is started for shooting.

The gesture detection unit photographs the inside of the vehicle at set time intervals to collect information about the basic image while closing (OFF) the vehicle engine and locking the side door.

At this time, as a basic image for determining more accurate intrusion into the vehicle interior, the vehicle interior may be photographed by changing a predetermined illuminance of the infrared LED of the gesture detection unit, and external photographing may be simultaneously performed to secure an image related to an indoor object according to a change in vehicle interior illumination.

As described above, after storing the collected basic image of the inside of the vehicle and the basic image of the outside of the vehicle, the gesture detection unit is switched to the sleep mode, and the motion detection unit is turned ON (ON).

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
