The presence or position of a traffic sign, a lane or a pedestrian may be detected through a forward image of the vehicle outputted from the image photographing unit 110. [

The radar unit 130 may be installed in front of the vehicle. The radar unit 130 may generate information about the distance to the front vehicle located ahead of the vehicle and the speed (or speed) And the measurement result can be output.

The ultrasonic sensor unit 150 may include a plurality of ultrasonic sensors. The ultrasonic sensor unit 150 may detect presence or absence of other vehicles or obstacles around the vehicle or around the vehicle by using the reflected ultrasonic signals generated from each of the plurality of ultrasonic sensors have.

The receiver 600 can receive signal information of a traffic light close to the vehicle through a Vehicle to Infrastructure (V2I), Vehicle to Everything (V2X), or Vehicle to Vehicle (V2V) communication. Also, the receiving unit 600 may receive the speed limit information of the road on which the vehicle is traveling.

Hereinafter, the concrete operation of the behavior detection unit 300 will be described in detail.

1) Violation of signal

The signal violation detecting unit 310 detects a traffic light of the vehicle from the forward image of the vehicle outputted from the image capturing unit 110 and detects the color of the signal light that is currently lit to detect a signal violation (or signal violation) It can detect. For example, the signal violation detecting unit 310 may determine that a signal violation has occurred when the vehicle passes the traffic light even though the color of the detected signal is red.

In another embodiment, the signal violation detection unit 310 may detect a signal violation based on the signal information received through the reception unit 600. [ For example, even if the traffic light in the front determined by the signal information is red, it can be determined that a signal violation has occurred if the vehicle violates the traffic light and enters the vehicle. At this time, whether or not the vehicle passed the traffic light can be determined using the forward image output through the image capturing unit 110, the traveling state of the vehicle (that is, the speed of the vehicle), or the location information of the vehicle. The location information of the vehicle can be received from a separate GPS device.

2) Center Line Infiltration Act

The center line invasion detection unit 320 may determine that a center line invasion has occurred when the center line that is detected by the vehicle is invaded. The center line may be determined based on the color of the sensed lane. That is, when the detected lane is yellow, the lane can be determined as a center line. That is, the center line invasion detection unit 320 may determine that the center line invasion operation is performed when the vehicle senses the center line and the vehicle invades the center line. According to an embodiment, the centerline invasion detection unit 320 may include a lane-keeping assist device or may mean the lane-keeping assist device itself.

3) Speeding

The overspeed detecting unit 330 may recognize a traffic sign from a forward image output from the image capturing unit 110 or a forward image output from a separate image capturing unit during driving of the vehicle. In addition, the overspeed detecting unit 330 can extract the speed limit of the section in which the vehicle is running from the recognized traffic sign. Then, the overspeed detecting unit 330 may detect the overspeed action by comparing the speed limit of the section in which the vehicle is running with the speed of the vehicle. That is, when the running speed of the vehicle is greater than the limit speed, it can be determined that the vehicle speed is excessive.

In another embodiment, the overspeed detecting unit 330 receives the limiting speed information of the road under driving from the receiving unit 600, compares the received limiting speed with the traveling speed, and when the traveling speed of the vehicle is greater than the limiting speed, It can be judged. At this time, the traveling speed of the vehicle may be received from the vehicle or measured using a separate gps device.

According to an embodiment, the overspeed detection unit 330 may include a traffic sign recognition device or a traffic sign recognition device.

4) Violation of crossing, U-turn and reverse prohibition

The traverse, U-turn, and reverse prohibition violation detection unit 340 can detect a traffic light and a sign from a forward image output from the image capturing unit 110 or a forward image output from a separate image capturing unit during driving of the vehicle. The traverse, turn-on and turn-back prohibition violation detecting unit 340 may detect traversal, U-turn, and backward prohibition violation detection unit 340 based on the signal information of the detected traffic lights, signboard information, And a reverse violation violation act.

In another embodiment, the traversing, U-turn and reverse prohibition violation detecting unit 340 receives signal information, traffic sign information (for example, prohibition of traverse, prohibition of U-turn or prohibition of backwarding) from the receiving unit 600, The information can be used to judge whether or not it is in violation of the synod, U-turn, and backward ban.

5) Violation of career change prohibition act

The course change prohibition violation detection unit 350 can determine that the course change prohibition violation is performed when the vehicle changes the lane in the section where the course change is prohibited. The lane change prohibited period can be recognized by detecting a lane which is a solid line instead of a dotted line. That is, the career change prohibition violation detecting unit 350 may detect a lane while driving, and may determine that it is a career change prohibition violation if an act of changing the lane is detected even though the lane is a solid line. According to an embodiment, the career change prohibition violation detection unit 350 may include a lane-keeping assist device or may be implemented as a lane-keeping assist device, and may detect a lane using a forward image output from the image photographing unit 110 It is possible.

6)

The rapid-motion detection unit 360 may determine that the rapid braking operation is performed when a sudden braking operation that is not suitable for a road running situation (such as an emergency or an accident) occurs while the vehicle is running. For example, when the distance from the preceding leading vehicle is equal to or greater than a predetermined distance (or a safety distance corresponding to the traveling speed or the limiting speed of the traveling section) or the degree of decrease in the distance from the leading vehicle does not exceed a predetermined degree It is possible to judge the sudden braking action when the degree of braking exceeds a predetermined level. At this time, the distance from the preceding vehicle ahead can be measured using the front image output from the image capturing unit 110, the output signal output from the ultrasonic sensor unit 150, the infrared sensor, or the radar unit 130.

7) Preceding Violation

The leading edge violation detecting unit 370 can detect the leading edge violating action. More specifically, the predilection violation detection unit 370 can determine whether to advance or not based on the distance to the preceding vehicle, and can detect whether or not it is violating the forwarding based on the direction of the predilection when detecting the predilation of the vehicle. If the lane is changed while the distance between the preceding vehicle and the side ahead is kept smaller than the predetermined reference value, it can be determined that the lane change prevention period If the lane is a solid line), it can be judged that it is a breach. In addition, if the lane change does not correspond to the lane change prohibition section, it can be judged that the lane change is violation. (However, in the case of the UK or Japan, it is possible to apply the relative standard.

8) Safety Distance Uncertainty Act

When the distance to the front vehicle is smaller than a predetermined distance, the distance to the preceding vehicle is smaller than the safety distance determined based on the traveling speed of the vehicle, It can be determined that the safety distance uncertainty action is smaller than the safety distance determined based on the speed limit. In addition, since the safety distance may not be temporarily secured, the safety distance uncertainty detector 380 may determine that the safety distance is not ensured continuously for a predetermined time period as the safety distance uncertainty.

9) Whether a horn occurs without justifiable reason

The horn occurrence occurrence detecting unit 390 can detect the occurrence of a horn even though there is no reason why the horn occurred. For example, if the obstacle (pedestrian) is detected ahead of the obstacle (or a pedestrian), if the adjacent vehicle is not detected, the incidence detection unit 390 can detect the incidence of the incidence . At this time, the occurrence of the horn may be detected using a sensor (for example, a voice recognition sensor, a noise detection sensor, or the like) included in the sensing unit 100 or a separate sensor.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
