Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to and the benefit of Korean Patent Application No. 10-2018-0160988, filed on Dec. 13, 2018, which is incorporated herein by reference in its entirety.

FIELD

The present disclosure relates to an apparatus for managing a vehicle intrusion, a system having the same, and a method thereof.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

In general, an intrusion detection device is installed in a vehicle to inhibit theft of the vehicle and the articles in the vehicle. Conventionally, the intrusion detection device uses an ultrasonic sensor, an infrared sensor, or the like.

However, since the conventional intrusion detection device focuses only on detecting an unauthorized occupant who intrudes into the vehicle at a time when the user is not present, we have discovered that a dangerous situation may occur when a user gets in the vehicle while an unauthorized occupant is present in the vehicle.

Thus, we have discovered a need for not only detecting an occupant who intrudes into a vehicle, but also promptly and accurately informing a user of information about the unauthorized occupant who intrudes into the vehicle immediately before or while the user gets in the vehicle.

The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure, and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

The present disclosure discloses a configuration which is capable of detecting an occupant who intrudes into a rear seat of a vehicle before, after or while a user gets in the vehicle and immediately informing the user of the fact, thereby allowing the user to cope with the intrusion.

FIG. 1 is a block diagram illustrating the configuration of a vehicle system including a vehicle intrusion management apparatus according to a form of the present disclosure.

Referring to FIG. 1, a vehicle system 10 may include a vehicle intrusion management apparatus 100 and a sensing module 200. The vehicle system 10 may communicate with a user terminal 500 and the user terminal 500 may include a smart key 510 and a mobile terminal 520. The mobile terminal 520 may include all portable mobile communication terminals such as a smartphone, a pad, a PDA, and the like.

The vehicle intrusion management apparatus 100 may determine the presence of an occupant who intrudes into a vehicle, and may notify the user of the presence of the occupant who intrudes into the vehicle. In this case, when the vehicle intrusion management apparatus 100 detects that an occupant intrudes into the vehicle before the user boards the vehicle, even though the user does not recognize the fact and presses a unlock button through a smart key, the vehicle intrusion management apparatus 100 may control the vehicle to maintain a locked state.

The vehicle intrusion management apparatus 100 may include a communication device 110, storage 120, a display 130, and a processor 140.

The communication device 110 is a hardware device implemented with various electronic circuits for transmitting and receiving a signal through a wireless or wired connection. In the forms, the communication device 110 may perform communication in the vehicle through CAN communication, LIN communication, or the like, may communicate with the sensing module 200, and may wirelessly communicate with the user terminal 500 outside the vehicle through wireless communication. The communication device 110 may be controlled by the processor 140 and may transmit a notification text to the user terminal 500 when it is determined that an occupant who intrudes into the vehicle is present before the user gets in the vehicle. Although the communication device 110 included in the vehicle intrusion management apparatus 100 is illuminated in FIG. 1, the form is not limited thereof and the communication device 110 may be separately implemented as a telematics terminal or the like of a vehicle. The communication device 110 may be controlled by the vehicle intrusion management apparatus 100 and request a SOS to a police server or the like in a dangerous situation.

The storage 120 may store a sensing result of the sensing module 200 and intruding occupant information (presence, position information, and the like) obtained by the processor 140, and previously registered occupant information (occupant image information, occupant volume information, the number of occupants, and the like). The storage 120 may include a storage medium having at least one type of a flash memory type, a hard disk type, a micro type, a card type of a memory (for example, an SD, XD memory, or the like), RAM (Random Access Memory), SRAM (Static RAM), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), MRAM (Magnetic RAM), a magnetic disc, and an optical disc.

The display 130 may be controlled by the processor 140 to display an informing screen when it is determined that an occupant who intrudes into the vehicle after the user gets in the vehicle. In this case, the informing screen may display the presence information of the intruding occupant, the location information of the intruding occupant, and the like. An example in which the informing screen is displayed on the display 130 will be described later with reference to FIGS. 6 and 7. In the present disclosure, although the display 130 is included in the vehicle intrusion management apparatus 100, the display 130 may be implemented as a head-up display (HUD) of the vehicle, a cluster, an audio video navigation (AVN) or the like. In addition, the display 130 may include at least one of a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), a light emitting diode (LED), an organic light emitting diode (OLED), an active matrix OLED (AMOLED), a flexible display, a bended display, and a three-dimensional (3D) display. Some of these displays may be implemented as transparent displays that are transparent or optically transparent to allow viewing of an outside. In addition, the display 130 may be provided as a touch screen including a touch panel, and may be used as an input device as well as an output device.

The processor 140 may be electrically connected to the communication device 110, the storage 120, the display 130, and the like, and may electrically control each component. The processor 140 may be an electric circuit that executes software commands and may perform various data processing and calculations described below.

When the presence of the occupant who intrudes into the vehicle is detected before the user gets in the vehicle, the processor 140 may notify the user by controlling an external lamp or horn of the vehicle. The processor 140 may control the external lamp to illuminate only in one direction. The control of the vehicle lamp will be described in detail later with reference to FIG. 5.

When the user is away from the vehicle by a preset distance or more, an ambient light is present, or the vehicle is located at an outdoor place, the processor 140 may turn on the exterior lamp at a bright intensity or control the flickering or turning on/off operation in a preset pattern. In addition, the processor 140 may control the external lamp of the vehicle to be turned on at a dark intensity or to be flickered or turned on or off in a preset pattern when the user is located within the preset distance from the vehicle, when the ambient light is dark, or when the vehicle is located at an indoor place. In this case, the exterior lamp of the vehicle may include at least one of a head lamp, a fog light, a tail light, a brake light, an emergency light, a room lamp, a daytime headlight, a welcome lamp, and a vehicle side light.

The processor 140 may inform the user by using at least one of an in-vehicle mood lamp, the display 130, and seat vibration when the intrusion of the occupant occurs after the user gets in the vehicle.

That is, the processor 140 may inform of whether the occupant who intrudes into the vehicle is present or the location of the occupant as a lighting position or lighting color of the in-vehicle mood lamp. The processor 140 may display whether the occupant who intrudes into the vehicle is present or the location of the occupant on the display to inform the user of the fact. The processor 140 may inform the user of whether the occupant who intrudes into the vehicle is present or the location of the intruding occupant as a vibration position or vibration intensity of a seat of the user.

The processor 140 may sense a change in the location of the occupant after a door is opened, determining whether the occupant who intrudes into the vehicle is present. The processor 140 may store occupant information and compare image information or volumetric information obtained by photographing the occupant who sits on a rear seat of the vehicle with information about the occupant registered in advance. When the image information or volumetric information does not correspond to the information about the occupant registered in advance, the processor 140 may determine the occupant as an intruder and inform the user of the fact. In this case, the processor 140 may obtain photographed image information of the occupant of the vehicle through a black box or the like.

When the number of occupants sitting on the rear seat of the vehicle is greater than or less than the number of persons stored in advance, the processor 140 may inform the user of the fact. Thus, the processor 140 may know whether an occupant such as a family, or the like properly gets in the vehicle, whether an occupant other than the family gets in the vehicle after the vehicle door is opened.

The sensing module 200 may sense the presence of an occupant who intrudes into the vehicle, sense the opening and closing of the door, and sense the presence of an occupant who is located close to the vehicle.

To this end, the sensing module 200 may include a door sensor 210, a radar sensor 220, and a camera 230, and if desired, may further include an ultrasonic sensor, a laser scanner and/or a corner radar, a Lidar, and the like.

The door sensor 210 senses the opening or closing of the vehicle door and provides it to the vehicle intrusion management apparatus 100.

The radar sensor 220 may be controlled by the vehicle intrusion management apparatus 100 and activated when the opening and closing of the door is sensed. The radar sensor 220 may detect the presence or absence of an occupant based on the movement and breathing of a human body in the vehicle, and detect the location of the occupant. The radar sensor 220 may be installed into a vehicle, and may be installed at the center of a vehicle rear seat, the end of a vehicle rear seat, or the like. In addition, the radar sensor 220 may sense whether an occupant is present, the location of an occupant, the volume of an occupant, or the like. The technique for detecting a change in the location and volume of an occupant by using the radar sensor 220 will be described in detail with reference to FIGS. 4A to 4D.

The camera 230 photographs the face of an occupant sitting at the rear seat of a vehicle and provides it to the vehicle intrusion management apparatus 100.

As described above, according to the present disclosure, it is possible to sense whether an intruder who intrudes into a vehicle before, after or while a user gets in the vehicle is present and inform the user of the fact, thereby assuring safety of the user and safety of the vehicle.

When an intruder gets in the vehicle before the user gets in the vehicle, the user may be informed of the fact. In this case, before the user gets in the vehicle, it is possible to perform the notification by utilizing an external lamp of the vehicle such as a smart key display, an emergency light, a horn, or the like before the user gets in the vehicle, and to perform the notification through a cluster display of the vehicle and an illumination color change after the user gets in the vehicle.

In addition, in an environment where it is difficult to identify the rear seat in the night or in a dark environment, in case where an unauthorized intrusion suddenly occurs after the user gets in the vehicle, when the intruder sneaks into the rear seat, the door opening is displayed through the cluster, and the user is informed of the fact that an occupant gets into the rear seat by changing the rear seat lighting color pattern.

In addition, according to the present disclosure, when it is desired to identify whether the boarding of an occupant on the rear seat is properly performed, by informing the user of whether the boarding is completed, it is possible to identify the boarding even if the user would like to identify whether the rear seat door is opened or an occupant such as a family or like properly boards the vehicle.

FIG. 2 is a diagram illustrating a method of sensing the presence or absence of an occupant in a rear seat according to a form of the present disclosure. As indicated by reference numeral 201 of FIG. 2, when an occupant is present in the rear seat inside the vehicle, it is possible to sense whether an occupant is present in the vehicle through the radar sensor 220 placed at an end of the vehicle rear seat or middle portion of the vehicle.

That is, the radar sensor 220 may be installed at the center of the rear seat in the interior of the vehicle to transmit a radar signal, and the vehicle intrusion management apparatus 100 may determine whether an occupant exists in the vehicle based on the intensity of a radar signal reflected by the occupant, the seat, or the like in the vehicle. That is, the vehicle intrusion management apparatus 100 may compare a combining value of the intensity of the radar signal reflected by at least one seat and the intensity of the signal reflected by the occupant sitting on at least one seat with a previously stored reference value to determine the presence or absence of an occupant. In addition, the intensity or distance information of a radar signal reflected and returned from a seat, a space right behind a drive seat and a passenger seat, and the like when the occupant is not present in the vehicle interior may be stored in advance, and the stored intensity or distance information may be compared with the intensity or distance information of a radar signal transmitted and reflected from the radar sensor 220 after the door opening is sensed, thereby sensing presence or absence of an occupant. Thus it is possible to sense an intruder even when the intruder hides under a seat without sitting in the seat.

Referring to reference numeral 202, an example of imaging a radar signal in a space between front and rear seats and in a rear seat area.

FIG. 3A is an exemplary diagram illustrating a screen of detecting and warning the location change of an occupant according to a form of the present disclosure. Referring to FIG. 3A, the vehicle intrusion management apparatus 100 may recognize a case where an occupant approaches the vehicle, and when the occupant approaching the vehicle is aboard the vehicle, the vehicle intrusion management apparatus 100 may sense the change of an occupant 301 to determine whether the occupant 301 gets in the vehicle. In this case, the vehicle intrusion management apparatus 100 may know the location of the occupant approaching the vehicle through an ultrasonic sensor, a camera photographing an outside of the vehicle, and the like, and may know the location of the occupant in the interior of the vehicle through an in-vehicle radar sensor, a camera for photographing the interior of the vehicle, or the like when the occupant gets in the vehicle.

FIG. 3B is a diagram illustrating an exemplary operation for determining an occupant by comparing and analyzing an occupant and occupant information stored in advance according to a form of the present disclosure.

Referring to FIG. 3B, children are usually boarded on the rear seat of a vehicle. The vehicle intrusion management apparatus 100 may store information about occupants mainly boarding on a vehicle in advance and determine whether the current occupant is the registered occupant in comparison with the information every time when an occupant is sensed. In this case, the vehicle intrusion management apparatus 100 may perform the occupant authentication based on the image information and the like, but may perform the occupant authentication based on the volume change of the occupant. That is, the vehicle intrusion management apparatus 100 may store the volumes (weights) of frequently boarding occupants 302 in advance and may compare it with the volume 303 of the currently boarding occupant to determine whether the occupant is unregistered or registered.

In addition, the vehicle intrusion management apparatus 100 may register the number of occupants who frequently get in the rear seats, and notify the user when all the occupants corresponding to the number of occupants do not get in the vehicle. For example, in case of a bus, a minibus, or the like, for a child care center, a nursery school, or the like, when the preset number of occupants do not board or get off, it is possible to inform the user of it, thereby allowing the number of occupants to be checked. In addition, when the number of occupants is greater than the number of occupants registered in advance, the vehicle intrusion management apparatus 100 may determine that unauthorized occupants exist in the vehicle and inform the user of the fact.

Hereinafter, a method of sensing the location and volume of an occupant in a vehicle will be described in detail with reference to FIGS. 4A to 4D.

FIG. 4A is a diagram illustrating a method of sensing the location of an occupant according to a form of the present disclosure.

Referring to FIG. 4A, it is assumed that a radar signal is reflected in a sensing range 411 of a radar sensor after being transmitted from a transmitter Tx as shown by reference numeral 401 and then received by receivers Rx1 to Rx4, when the vehicle intrusion management apparatus 100 enters the sensing range 411 of the radar sensor in which an object 412 is set as shown by reference numeral 402, by using the difference between the distance values of the object 412 and the receivers Rx1 to Rx4 based on the signals received by the receivers Rx1 to Rx4, the coordinates of the object 412 may be calculated. In such a manner, the vehicle intrusion management apparatus 100 of the vehicle may calculate the coordinates of the object located in a specific space (radar sensor detection range).

FIG. 4B is a diagram illustrating a method of sensing the location of an occupant in a rear seat of a vehicle according to a form of the present disclosure. FIG. 4C is a diagram illustrating a method of sensing the location of an occupant through a radar sensor according to a form of the present disclosure.

As shown by reference numeral 403 of FIG. 4B, the radar sensor 220 may be installed in the vehicle, and may calculate the distance value based on the light transmitted and reflected to the rear seat space.

As shown by reference numeral 404 of FIG. 4B, when any occupants are not in the rear seat space, the distances to the specific area 430 of the rear seat space have values of 189, 179, 169, 178, 185, and 172. As shown by reference numeral 405, when an occupant enters the rear seat space, the distances from the radar sensor 220 to the rear seat space are reduced to 65, 75, 85, 77, and so on.

As shown by reference numeral 406 of FIG. 4C, when any occupants do not exist in the rear seat space, the distance from the radar sensor 220 to the rear seat space is 180. As shown by reference numeral 407, when an occupant exists, the distance from the radar sensor 220 to the rear seat space is 75, so that the distance from the radar sensor 220 to the rear seat space is shortened to 75 when an occupant exists.

FIG. 4D is a diagram illustrating a method of classifying the volume of an occupant according to a form of the present disclosure.

In FIG. 4D, reference numeral 408 of FIG. 4 denotes a distance value when a child is aboard, and reference numeral 409 of FIG. 4D denotes a distance value when an adult or a physically large person is aboard.

The vehicle intrusion management apparatus 100 may divide a field-of-view (FOV) space of a radar into various coordinates (each grid line) by using several radar transmitters Tx and a radar receiver Rx. The vehicle intrusion management apparatus 100 may utilize the numerical value of the radar reflected wave (distance) in the empty space which is shorter when an occupant is present. The area varying with the volume of an occupant may be large and the vehicle intrusion management apparatus 100 may know the volume of the occupant based on the area. That is, since the size of the area 421 in which the distance value of reference numeral 408 is changed is smaller than the area 422 in which the distance value of reference numeral 409 is changed, it may be determined that a child boards in the area 421 in which the distance value of reference numeral 408 is changed and an adult boards in the area 422 in which the distance value of reference numeral 409 is changed. In addition, the vehicle intrusion management apparatus 100 may grasp more finely than the exemplary image corresponding to the resolution of the radar sensor 220.

Hereinafter, an example of a method of notifying the user of the presence of an unauthorized occupant will be described in detail with reference to FIGS. 5 to 11.

FIG. 5 is a diagram illuminating an example of performing an intruder notification through a vehicle lamp control according to a form of the present disclosure. The vehicle intrusion management apparatus 100 may control the operation of the vehicle lamp based on vehicle setting values, a location of an occupant who intrudes into the vehicle, a degree of risk, and the like.

Referring to reference numeral 501 of FIG. 5, the vehicle intrusion management apparatus 100 controls a lamp to be lightened brightly and strongly when a user tries to open the door from a distance (e.g., distance of 5 m or more), an ambient light exists, or it is in an outdoor condition. For example, when the user tries to open the door at a distance of 5 m or more, the vehicle intrusion management apparatus 100 may allow a head lamp 511, a daytime running light (DRL), a fog light 512, a rear lamp, a brake light, and the like to be turned on or flickered to perform a pattern recognizable by the user, such that the user may recognize the fact before getting in the vehicle. For example, the pattern recognizable by a user may include a flicker of a headlamp, lightening only for one second once, and the like.

The vehicle intrusion management apparatus 100 performs notification to the user in dark illumination under conditions in which the user approaches the vehicle (e.g., within a distance of 5 m), the vehicle is in a dark place without ambient light, or an indoor parking lot. For example, the vehicle intrusion management apparatus 100 may operate a welcome lamp 514, a vehicle side lamp 513, and the like to perform a notification to the user.

Referring to reference numeral 502 of FIG. 5, it is possible to control the vehicle lamp corresponding to the location of an intruder. For example, when the occupant intruding into the vehicle is located at the right side 521 of the vehicle, the vehicle intrusion management apparatus 100 may turn on or flicker the lamp on the right side of the vehicle, and when the occupant is located at the left side 522 of the vehicle, the vehicle intrusion management apparatus 100 may turn on or flicker the lamp on the left side of the vehicle, such that the user may estimate the location of the occupant in the vehicle.

FIG. 6 is a diagram illustrating an example of performing an intruder notification through an in-vehicle mood lamp and a display according to a form of the present disclosure.

In a dangerous situation such as the presence of an unauthorized intruder, a weak notification which is identified only by the user is desired rather than a strong notification. Referring to reference numeral 601 of FIG. 6, the vehicle intrusion management apparatus 100 may perform a notification through a small brightness change of in-vehicle mood lamps 611, 612, and 613, a color change, a cluster lamp, and the like, thereby allowing the user to be noticed.

In addition, referring to reference numeral 602 of FIG. 6, the vehicle intrusion management apparatus 100 may output a text “Identify occupant sitting on rear seat” to a display window 621 of a cluster, thereby allowing the user to identify it.

FIG. 7 is a diagram illustrating an example of displaying a location of an occupant in a vehicle rear seat according to a form of the present disclosure.

Referring to reference numeral 701 of FIG. 7, it may be understood that the vehicle intrusion management apparatus 100 displays a vehicle rear seat state on a display window 711 in a cluster.

Referring to FIG. 11, when an occupant existence notification is performed through the user terminal 500 that does not include a display as indicated by reference numeral 1101, the vehicle intrusion management apparatus 100 may display the presence or absence of an occupant through vibration or a lamp. As indicated by reference numeral 1102, the presence or absence of an occupant may be known by using whether state indication lamps 1112 and 1113 are turned on or off. In addition, it is possible to know the location of the intruding occupant based on the lighting location of the state indication lamp. For example, when the state indication lamp 1112 on the left is turned on, the vehicle intrusion management apparatus 100 may determine that the occupant is located at the left side of the vehicle, when the state indication lamp 1113 on the right is turned on, the vehicle intrusion management apparatus 100 may determine that the occupant is located at the right side of the vehicle, and when all the state indication lamps 1112 and 1113 on the left and right are turned on, the vehicle intrusion management apparatus 100 may determine that the occupant is located in the middle. In addition, it is possible to recognize the intrusion and the location by changing the flicker pattern of the left and right state indication lamps 1112 and 1113. For example, when the state indication lamps 1112 and 1113 are flickered every interval of two seconds, the vehicle intrusion management apparatus 100 may determine that the occupant is located at the left. When the state indication lamps 1112 and 1113 are flickered every interval of one second, the vehicle intrusion management apparatus 100 may determine that the occupant is located at the right. When the state indication lamps 1112 and 1113 are rapidly flickered every interval of 0.5 seconds, the vehicle intrusion management apparatus 100 may determine that the occupant is located in the middle.

Hereinafter, a vehicle intrusion management method for detecting an occupant before the user gets in the vehicle according to a form of the present disclosure will be described in detail with reference to FIG. 12.

In addition, in the description of FIG. 12, it may be understood that the operation described as being performed by the apparatus is controlled by the processor 140 of the apparatus 100.

Referring to FIG. 12, in operation S110, the vehicle intrusion management apparatus 100 stores and memorizes a getting off state. Thereafter, the vehicle is parked and is turned off.

In a state in which the vehicle is in the turned-off state, when the opening of the door is recognized in operation S120, the vehicle intrusion management apparatus 100 may detect the presence of an occupant in the vehicle interior and may perform a text notification to the user in operation S130. In this case, the vehicle intrusion management apparatus 100 may detect whether the door is opened through the door sensor 210, and detect whether the occupant is present in the vehicle through the radar sensor 220 or the camera 230. In addition, the vehicle intrusion management apparatus 100 may continuously monitor the occupant who does not move while hiding in the vehicle rear seat through the radar sensor 220, and may obtain biometric information of the occupant such as respiration, heartbeat, and the like rather than a simple movement, thereby continuously monitoring the occupant state.

Thereafter, when a user having the user terminal 500 such as the smart key 510, the mobile terminal 520, or the like capable of communicating with the vehicle system 10, approaches the vehicle, the vehicle intrusion management apparatus 100 may detects the approach of the user in operation S140, and in operation S150, may output a warning to the user that the occupant is present in the vehicle interior. In this case, the vehicle intrusion management apparatus 100 may perform an alarm by performing output of a horn, a head lamp, a speaker, and the like of the vehicle. As described above, when the presence of the occupant intruding into the vehicle is detected, the vehicle intrusion management apparatus 100 may maintain the door lock state to protect the user even when the user approaches the vehicle and presses an unlock button. In addition, when the user presses the unlock button, the vehicle intrusion management apparatus 100 notifies the presence of the occupant who intrudes into the room through vibration, the state indication lamp, the mobile terminal, or the like again. Thereafter, after the user identifies the intruder or the problem situation is terminated, the vehicle intrusion management apparatus 100 releases the unlock mode lock by pressing the unlock button for a long time or a smartphone intrusion detection confirmation button.

As described above, according to the present disclosure, it is possible to identify an intrusion of an occupant who intrudes into the vehicle, inhibiting an accident that may occur due to it, and identify an occupant in the vehicle in a dark parking lot or in a dark night time in which it is difficult to identify the occupant, thereby giving the user peace of mind. Specifically, for female drivers or elder people who may surprise even a sign of a person being around, it is possible to identify the vehicle state in advance, thereby giving peace of mind.

Hereinafter, a method of detecting an occupant before a user gets into a vehicle illustrated in FIG. 12 will be described in more detail with reference to FIG. 13. FIG. 13 is a flowchart illustrating a method of detecting an occupant before a user gets into a vehicle according to a form of the present disclosure.

Referring to FIG. 13, in operation S111, the vehicle intrusion management apparatus 100 activates the radar sensor 220 when door opening and closing are detected by the door sensor 210.

Thereafter, in operation S112, the vehicle intrusion management apparatus 100 may detect the presence or absence of an occupant in the interior of the vehicle by the radar sensor 220. In operation S113, when there is an occupant in the interior of the vehicle, the vehicle intrusion management apparatus 100 transmits a notification text to the user terminal 500. Accordingly, the user may recognize in advance that there is an unauthorized occupant in the interior of the vehicle through the notification text received by the user terminal 500.

In addition, when the user having the user terminal 500 approaches the vehicle in operation S114, the user terminal 500 and the vehicle intrusion management apparatus 100 transmit and receive user authentication, a start-on signal, a door unlocking signal in operation S115. In operation S116, the vehicle intrusion management apparatus 100 recognizes the approach of the user and outputs a warning. Thus, the user may intuitively recognize the presence of an intruder through a warning lamp or a warning sound.

As described above, according to the present disclosure, it is possible to allow the user to identify in advance whether an intruder is present in a vehicle, so that a dangerous situation such as a vehicle theft or a human accident may be inhibited in advance.

Hereinafter, a method of managing a vehicle intrusion while or after a user gets into a vehicle according to another form of the present disclosure will be described in detail with reference to FIG. 14.

That is, FIG. 14 illustrates an example of a case where a user gets into a vehicle before another occupant intrudes into the vehicle.

Referring to FIG. 14, when the user recognizes door opening through the door sensor 210 in operation S220 after the user gets into the vehicle in operation S210, in operation S230, the vehicle intrusion management apparatus 100 detects whether an occupant is present in the rear seats through the radar sensor 220 or the camera 230. When there is an occupant in the rear seat, the vehicle intrusion management apparatus 100 informs the user of information about the rear seat occupant in operation S240. The vehicle intrusion management apparatus 100 may perform a notification of the presence of the occupant in the rear seat through a cluster, a speaker, and the like of the vehicle.

In this case, the vehicle intrusion management apparatus 100 may determine whether the occupant in rear seat is a registered occupant based on the previously stored occupant information, and may inform the user of it. That is, when the occupant in the rear seat is not registered, the user may be informed that there is an unauthorized occupant in the vehicle, and when the occupant is a registered passenger, the vehicle intrusion management apparatus 100 may not perform a separate notification to the user.

The vehicle intrusion management apparatus 100 may notify the user of the presence of an occupant who intrudes into the rear seat while the user gets in the vehicle, and at the same time, request an SOS to the police to quickly cope with it.

Hereinafter, a vehicle intrusion management method for identifying occupant information and providing the information to a user according to another form of the present disclosure will be described in detail with reference to FIG. 15.
