1 is a schematic block diagram of an endless crossing prevention system according to an embodiment of the present invention.

Referring to FIG. 1, an endless anti-traction system in accordance with the present embodiment includes an infrastructure device 100 and a vehicle 400.

The infrastructure device 100 can detect a pedestrian crossing the roadway and send a warning signal to the pedestrian crossing the roadside. The infrastructure device 100 is a device that transmits an unauthorized traverse detection signal to a nearby vehicle when it detects an unauthorized traversing pedestrian and controls the transmission of an alarm signal in synchronization with the vehicle. The infrastructure device 100 may be included in any one of a pedestrian signal lamp and / or a vehicle signal lamp, but the present invention is not limited thereto. The infra-structure device 100 may be configured as a separate device to detect a pedestrian crossing unauthorizedly, . A more detailed description of the infrastructure device 100 will be described later with reference to FIGS.

The vehicle 400 may be a two-wheel and / or four-wheel drive device that generally travels on the road, and is described as an automobile in this embodiment.

The vehicle 400 can send and receive signals through communication with the above-described infrastructure device 100, receive signals from the infrastructure device 100 that can recognize the endless pedestrian, have. A more detailed description regarding the vehicle 400 will be described later with reference to Figs.

2 is a block diagram of an infrastructure device according to an embodiment of the present invention.

The infrastructure device 100 can detect a walker crossing the driveway and generate a warning signal to recognize the danger to the walker. In addition, the infrastructure device 100 transmits an unauthorized traverse sense signal to the vehicle 400 through communication with the vehicle 400, and controls the warning signal by synchronizing the warning device that transmits the warning signal with the vehicle 400 It is possible to recognize the risk situation more effectively by the walker crossing the driveway. In the present embodiment, it is assumed that the person is a person.

2, the infrastructure device 100 includes a sensing unit 210, a walking alert unit 220, a device communication unit 230, and a device control unit 240.

The sensing unit 210 senses a pedestrian crossing the roadway.

The sensing unit 210 may include a thermal imaging camera, an infrared camera, and an ultrasonic sensor. The sensing unit 210 may sense a pedestrian crossing the road through a camera and a sensor. For example, the sensing unit 210 may recognize a person as a person when the walker entering the roadway using a thermal imaging camera or an infrared camera is a human shape, and sense the walker. At this time, the sensing unit 210 may sense the walker in consideration of conditions such as the size, moving direction, and moving speed of the object. The sensing unit 210 may determine whether the walker is a person or a vehicle in consideration of the above-described conditions. Meanwhile, the sensing unit 210 may store the position information in a separate storage (not shown) in advance.

Meanwhile, the sensing unit 210 may be connected to a pedestrian signal lamp and / or a vehicle signal lamp. When the signal of the pedestrian signal lamp is red and the signal of the vehicle signal lamp is blue, the sensing unit 210 can identify the pedestrian and detect whether the passenger is crossing.

When the sensing unit 210 senses the endless pedestrian, the walking warning unit 220 sends a warning signal to the pedestrian who crosses the endlessly.

The walking warning unit 220 can send a warning signal to the pedestrian who crosses through the lighting and the speaker. The warning signal emitted through the loudspeaker may be a pre-stored hazard notification, and the illumination may be an illumination with universal joint function capable of moving in multiple axes that can be rotated in accordance with the direction of movement of the endless transversal. On the other hand, the walking warning section 220 may include an illumination and a speaker having a supergain characteristic. The super-directional characteristic is a characteristic that can radiate (emit) sound or light only to a specific area. For example, supergain speakers emit (emit) an audio signal into an ultrasonic band (20 kHz to 80 kHz) signal to produce a narrow steering angle, and the air reproduces the audio signal within the ultrasound directing angle, Sound can be emitted (emitted) only to the area. The lighting and the speaker may be installed in a vehicle signal lamp and / or a pedestrian signal lamp, but the present invention is not limited to this, and the lighting and the speaker may be installed in a separate position as long as the warning signal can be transmitted to the pedestrian and the vehicle.

The walking warning unit 220 can immediately transmit a warning signal when the sensing unit 210 senses a pedestrian crossing the driveway. For example, when the sensing unit 210 senses a pedestrian crossing a road, the walking warning unit 220 can transmit a warning signal to the endless crossing object through the illumination and / or the speaker to recognize the dangerous situation have.

The device communication unit 230 can transmit the endless crossing detection signal to the surrounding vehicle when the sensing unit 210 senses a pedestrian crossing the endlessly. For example, when the sensing unit 210 senses a pedestrian crossing at an end, the device communication unit 230 can broadcast an endless crossing detection signal to surrounding vehicles in real time or at a preset cycle. The endless crossing detection signal may include position information of the sensing unit 210. Meanwhile, the device communication unit 230 can transmit an unauthorized traverse detection signal to the vehicle 400 based on V2I (Vehicle to Infrastructure) communication. V2I communication is a wireless communication technology between a vehicle and an infrastructure (base station). By exchanging change information of a rapidly changing operating environment in real time, it is possible to change lane change warning, collision line warning, danger situation warning, The same service can be provided. Meanwhile, the device communication unit 230 may transmit the endless crossing detection signal to the vehicle 400 when the vehicle 400 enters within a predetermined radius. At this time, the entrance of the vehicle can be detected by the sensing unit 210 through the infrared sensor or the like. For example, when the sensing unit 210 senses a pedestrian crossing the vehicle, the infrared sensor senses the vehicle 400 entering the vehicle within a predetermined radius, and transmits an unauthorized crossing detection signal to the vehicle 400. At this time, it is preferable that the infrared sensor is installed so as to detect the vehicle 400 entering the crosswalk direction. For example, when the preset radial range is 1 Km, the device communication unit 230 senses a pedestrian crossing the sensing unit 210, enters the vehicle 400 within a radius range by the infrared sensor, It is possible to transmit an unauthorized traverse detection signal to the vehicle.

The device control unit 240 controls the above-described components as a whole. The device control unit 240 can control the transmission of the warning signal when the device communication unit 230 receives the vehicle proximity signal from the vehicle.

Meanwhile, the infrastructure device 100 according to another embodiment of the present invention may further include a synchronization unit 310.

3 is a configuration diagram of an infrastructure device according to another embodiment of the present invention.

In the description of FIG. 3, the components having the same reference numerals as those of FIG. 2 include both functions and operations described with reference to FIG. 2, and therefore, description thereof will be omitted.

Referring to FIG. 3, the infrastructure device 100 according to the present embodiment may further include a synchronization unit 310.

When the device communication unit 230 receives the vehicle proximity signal from the vehicle as a response signal after the device communication unit 230 transmits the endless crossing detection signal to the surrounding vehicle, the synchronization unit 310 transmits and receives a synchronization signal with the vehicle, 220 can be synchronized. For example, when the device communication unit 230 transmits an unauthorized traverse detection signal to the vehicle, the synchronization unit 310 may receive the vehicle proximity signal from the vehicle as a response signal. At this time, the vehicle proximity signal may be a signal transmitted from the device communication unit 230 in response to the vehicle receiving the endless crossing detection signal. That is, when the sensing unit 210 senses a pedestrian crossing a road, the device communication unit 230 may be a signal that broadcasts to surrounding vehicles in real time or at a predetermined cycle. At this time, the endless crossing detection signal can be transmitted within the communication radius range in which the device communication unit 230 can transmit the signal. The communication radius range can be preset and can be set arbitrarily by the user. For example, the communication radius range may be a range in which the vehicle receiving the unauthorized traverse detection signal may be aware of the danger, and it will be described as 1 km in the present embodiment. On the other hand, the vehicle proximity signal may include position information of the vehicle, direction information of the vehicle, and the like. For example, when the sensing unit 210 senses a pedestrian crossing the vehicle, the device communication unit 230 may broadcast an unauthorized crossing detection signal to vehicles within a range of 1 km. At this time, the unauthorized traverse detection signal can be received by all vehicles within a range of 1 km. However, as will be described later, the vehicle 400 receiving the unauthorized crossing detection signal transmits the vehicle proximity signal to the infrastructure device (not shown) based on the location of the infrastructure device 100, the location information of the vehicle 400, 100). In another embodiment, the vehicle 400 having received the unauthorized traverse detection signal may send a vehicle proximity signal to the infrastructure device 100 based on distance information and direction information calculated based on the location of the infrastructure device 100 and its location information, (100). For example, a vehicle that receives an unauthorized traverse detection signal from the infrastructure device 100 may calculate the distance based on the location of the infrastructure device 100 and its own location information, and based on the calculated distance information, When approaching the structure device 100, the vehicle proximity signal may be transmitted to the infrastructure device 100. Meanwhile, the vehicle 400 receiving the unauthorized crossing detection signal from the infrastructure device 100 calculates a distance based on the location of the infrastructure device 100 and its own location information, and based on the calculated distance information If the vehicle is away from the infrastructure device 100, it may not transmit a vehicle proximity signal.

When the device communication unit 230 receives the vehicle proximity signal, the synchronization unit 310 can synchronize the vehicle 400 and the walking alert unit 220 by transmitting and receiving a synchronization signal with the vehicle 400. [ For example, the illumination included in the walking warning unit 220 is synchronized with the headlight of the vehicle 400, and the speaker included in the walking warning unit 220 can be synchronized with the speaker of the vehicle. The synchronized gait warning unit 220 may be controlled by a device control unit 240 to be described later to emit (emit) a warning signal.

4 is a functional block diagram of a control apparatus for a vehicle according to an embodiment of the present invention.

The vehicle 400 may communicate with the infrastructure device 100 as shown in Figs. 2-3. The vehicle 400 may communicate with an infrastructure device 100 that includes a sensing unit 210 that senses a pedestrian crossing the driveway. Communication can be performed through V2I communication technology.

4, the vehicle 400 according to the present embodiment includes a vehicle communication unit 410, a position display unit 420, a distance calculation unit 430, a vehicle warning unit 440, and a vehicle control unit 450 can do.

The vehicle communication unit 410 can receive the endless crossing detection signal from the infrastructure device 100. [ The endless crossing detection signal may include position information of the sensing unit 210.

The position display unit 420 may include navigation for displaying the position of the sensing unit 210 based on the position information of the sensing unit 210 included in the endless transit sensing signal received by the vehicle communication unit 410. Navigation may be to display a map or navigate a route to a destination and guide the navigated route. The navigation may be a terminal such as a navigation-only device and / or a smart phone equipped with a navigation program (for example, an application). The navigation may be pre-installed in the vehicle or carried by the driver.

The relative position confirmation unit 430 can check the relative position and movement direction of the sensing unit 210 and the vehicle 400 and can determine whether the vehicle 400 is close or not according to the confirmed information. At this time, the current position of the vehicle 400 can receive and store location information from the GPS satellites. In addition, the position of the sensing unit 210 may be included in the endless transit detection signal received by the vehicle communication unit 410 and may be confirmed. For example, when the vehicle 400 moves toward the sensing unit 210 and the distance from the sensing unit 210 is shortened, the position determining unit 430 determines that the vehicle 400 approaches the sensing unit 210 Able to know. On the contrary, when the vehicle 400 moves in the direction opposite to the sensing unit 210 and the distance from the sensing unit 210 is increased, the position determining unit 430 moves the vehicle 400 away from the sensing unit 210 .

When the vehicle communication unit 410 receives the endless crossing detection signal from the infrastructure device 100, the vehicle warning unit 440 receives an operation (e.g., a headlight operation operation) from the driver of the vehicle, A warning signal can be transmitted. At this time, the vehicle warning section 440 may include a headlight, an emergency light, a horn, and the like. However, the present invention is not limited to this, and the vehicle warning unit 440 may be configured to emit (emit) light or light through a light to recognize a danger.

The vehicle control unit 450 can synchronize the infrastructure device 100 and the vehicle warning unit 440 to control the transmission of the warning signal by the operation input from the user. For example, when the illumination of the infrastructure device 100 and the headlight of the vehicle warning section 440 are synchronized, the vehicle control section 450 controls the vehicle warning section 440 A warning signal such as light can be transmitted through the headlight of the vehicle. At this time, the infrastructure device 100 synchronized with the vehicle warning unit 440 may also send a warning signal by the control operation of the device control unit 240. [ For example, when the headlights of the vehicle and the illumination of the infrastructure device 100 are synchronized, the device control unit 240 can control the warning signal to be transmitted through the illumination.

The vehicle control unit 450 controls the vehicle communication unit 410 to transmit the vehicle proximity signal 100 to the infrastructure device when the relative position determination unit 430 recognizes that the vehicle 400 is approaching the infrastructure device 100 To be transmitted. The vehicle control unit 450 controls the vehicle communication unit 410 to transmit and receive the synchronization signal. After synchronization, the vehicle control unit 450 can control the vehicle warning unit 440 to transmit the warning signal. That is, the vehicle control unit 450 recognizes that the vehicle is approaching an unauthorized crossing pedestrian, transmits a vehicle proximity signal to the infrastructure device 100, synchronizes the warning device between the vehicle and the infrastructure device 100, By sending a signal, it is possible to more effectively recognize the danger situation to an unauthorized traverse pedestrian.

On the other hand, when the relative position determination unit 430 recognizes that the vehicle 400 is distant from the infrastructure device 100, the vehicle control unit 450 can immediately release the synchronization between the infrastructure device 100 and the vehicle.

The synchronization between the infrastructure device 100 and the vehicle warning section can be released. Thereafter, the vehicle control section 450 can control the vehicle warning section 440 to stop sending the warning signal. In other words, the vehicle control unit 450 can stop the transmission of the vehicle proximity signal in recognition of the fact that the vehicle is moving away from the endless pedestrian, and can stop the transmission of the warning signal.

Meanwhile, when the vehicle receives the unauthorized crossing detection signal from the infrastructure device 100 as described above, it can transmit the unauthorized crossing detection signal to another vehicle using a V2V (Vehicle to Vehicle) communication technique.

5 is a functional block diagram of a control apparatus for a vehicle according to another embodiment of the present invention.

In describing FIG. 5, the components having the same reference numerals as those in FIG. 5 include both functions and operations described with reference to FIG. 4, and therefore, description thereof will be omitted.

Referring to FIG. 5, the vehicle 400 according to the present embodiment further includes a synchronization mode setting unit 510.

The synchronization mode setting unit 510 sets the synchronization mode setting unit 510 to the position display unit 420 so that the vehicle communication unit 410 can set the device to be synchronized by the selection of the vehicle occupant when the vehicle communication unit 410 receives the endless crossing detection signal from the infrastructure device 100 The setting mode can be output on the included navigation. The setting mode may include an automatic mode and / or a manual mode. When the automatic mode is selected by the vehicle occupant, the vehicle warning unit 440 included in the vehicle and the infrastructure device 100 are synchronized. At this time, matching information of objects to be synchronized with each other may be preset and stored. Specifically, the vehicle warning unit 440 included in the vehicle and the walking warning unit 220 included in the infrastructure device 100 can be synchronized. On the other hand, when the passenger mode is selected by the vehicle occupant, the list of the devices included in the vehicle warning unit 440 to be synchronized with the walking warning unit 220 included in the infrastructure device 100 is output on the navigation system . At this time, the list of the devices included in the vehicle warning unit 440 may be a headlight, an emergency light, a horn, or the like. At this time, if at least one of the output list is selected, the walking warning unit 220 of the selected device and the infrastructure device 100 may be synchronized.

The trotting pedestrian sensing step detects 610 a pedestrian that the infrastructure device 100 crosses the roadway.

In the warning signal transmitting step, the infrastructure device 100 sends an alarm signal to the pedestrian crossing 620. In the warning signal transmitting step, when the infrastructure device 100 detects a pedestrian crossing the traffic lane, the warning signal can be transmitted immediately. For example, as shown in FIG. 8, a warning signal can be transmitted to a pedestrian who crosses the street. FIG. 8 is a diagram illustrating an example in which an alert signal is transmitted in the infrastructure device 100 according to an embodiment of the present invention. Referring to FIG. 8, the infrastructure device 100 is provided in a separate device, and when detecting an unauthorized crossing pedestrian, the pedestrian may be illuminated to recognize a danger due to crossing. On the other hand, the illumination may be installed in a pedestrian signal lamp and / or a vehicle signal lamp, and may be an illumination with a universal joint function capable of moving in multiple axes which can be rotated in accordance with the moving direction of the endless cross member. In addition, the infrastructure device 100 may include a speaker in a configuration for transmitting a warning signal. At this time, the alarm sound previously stored through the speaker can be sent out as a warning signal. Lighting and speakers can have super-directional characteristics, which can radiate (emit) sound or light only to specific areas.

When the infrastructure device 100 senses a pedestrian crossing unauthorizedly, the step of transmitting an unauthorized crossing detection signal transmits an unauthorized crossing detection signal to the vehicle 400 (630).

The warning signal transmission control step controls the transmission of the warning signal after synchronizing the vehicle 400 and the infrastructure device 100 (630) (640).

On the other hand, when the infrastructure device 100 receives the vehicle proximity signal from the vehicle 400 as the response signal after transmitting the endless crossing detection signal to the vehicle 400 before sending the warning signal, the infrastructure device 100 transmits the synchronization signal So that the vehicle 400 and the walking warning unit 220 can be synchronized. Infrastructure device 100 may control the transmission of an alert signal after synchronization.

7 is a flowchart illustrating a method of determining a walking object in an infrastructure device according to an embodiment of the present invention.

Referring to FIG. 7, the infrastructure device 100 according to the present embodiment can determine whether the detected object is a person or a vehicle.

First, the infrastructure device 100 may recognize the object through the thermal imaging camera (710). At this time, it is explained that the device for recognizing the object is a thermal camera, but it is not limited thereto, and it may be any device capable of recognizing an object such as a thermal infrared camera or an ultrasonic sensor.

Then, the infrastructure device 100 may determine 720 whether the vehicle is a person or a vehicle considering the size, moving direction, moving speed, etc. of the object (720) (740).

The infrastructure device 100 can determine a person as a person if the subject moves in a direction that crosses between the lead and the destination, and the traveling speed is less than 20 km. On the other hand, the infrastructure device 100 can discriminate the vehicle when the object moves in a direction perpendicular to the direction (i.e., the direction crossing the direction between the vehicle and the vehicle) and the traveling speed is 20 km or more.

FIG. 9 is a view illustrating an example in which a synchronization setting mode is shown in a navigation system of a vehicle according to an embodiment of the present invention. FIG. Fig.

According to an embodiment of the present invention, when the vehicle 400 receives an unauthorized traverse sense signal from the infrastructure device 100, it can select the synchronization mode by selection of the vehicle occupant.

9 and 10, when the vehicle 400 receives an unauthorized crossing detection signal from the infrastructure device 100, the synchronization setting mode may be displayed on the screen of the navigation provided in the vehicle. The synchronization setting mode may be an automatic mode or a manual mode.

When the passenger of the vehicle selects the automatic mode, synchronization between the vehicle 400 and the infrastructure device 100 is performed according to a predetermined synchronization procedure, so that the warning signal generation operation can be performed at the same time. For example, when the illumination included in the infrastructure device 100 and the headlight of the vehicle are synchronized, when an alarm signal is generated by either the infrastructure device 100 or the vehicle, an alarm signal is sent to the infrastructure device 100 ) And the headlights of the vehicle 400. [0054] That is, when the infrastructure device 100 generates a warning signal for emitting light by illumination, a warning signal for emitting light simultaneously occurs in the headlight of the vehicle 400. Conversely, if a user of the vehicle 400 generates a warning signal that activates the headlights of the vehicle 400 to emit light, the illumination of the synchronized infrastructure device 100 also causes light A warning signal may be generated.
