1 is a schematic view of an embodiment of the present invention.

The vehicle 10 can communicate with the telematics center 20. The vehicle 10 is traveling on a single lane. An obstacle 30 may be present on the primary lane. The obstacle 30 may be a parachute away from the preceding vehicle, and may be a road crack, a dent, or the like.

The driver of the vehicle 10 can detect the obstacle 30 and change the lane into a two-lane road while braking.

In this case, when the brakes are stepped on by the driver, the electronic system of the vehicle 10 can shoot the obstacle 30 through the camera mounted on the vehicle and recognize the obstacle 30 from the photographed image.

The electronic system of the vehicle 10 can specify the position of the obstacle 30 in conjunction with the navigation system. The electronic system of the vehicle 10 may also transmit the location of the obstacle 30 to the telematics center 20.

When the telematics center 20 receives the predetermined number of the obstacle 30 information, the telematics center 20 transmits the information to the following vehicle passing the point of the obstacle 30 to prevent an accident.

2 is a view showing the positions of a plurality of cameras mounted on a vehicle according to an embodiment.

The vehicle 10 may include at least one photographing unit 110-1 to 110-4. At least one photographing unit 110-1 to 110-4 can be activated by a trigger command. For example, when the vehicle pedal is depressed while the vehicle 10 is running, the photographing units 110-1 to 110-4 can be triggered. However, although the photographing unit is shown as a plurality of photographing units, the photographing unit may be composed of a single number, and the mounting position may vary.

3 is a block diagram of an electronic system according to an embodiment.

3, the electronic system 100 may include a photographing unit 110, a communication unit 120, a memory 130, and a control unit 140. In addition, the electronic system 100 may include or be configured separately from the navigation system 50.

The photographing unit 110 may be disposed on the front, the side, the rear, and the like of the vehicle as shown in FIG. The photographing unit 110 can mainly photograph an obstacle in front of the vehicle.

The communication unit 120 may be connected to the external center 200. The external center 200 may be a telematics center, but is not limited thereto.

The memory 130 stores necessary data under the control of the controller 140.

The control unit 140 is an element for controlling the electronic system 100 as a whole. The control unit 140 may control the photographing unit 110 to photograph an obstacle and recognize the position of the obstacle by recognizing the obstacle.

For example, the control unit 140 may recognize that the obstacle is located in a specific lane on the road based on the image photographed by the photographing unit 110. [

The control unit 140 can transmit the position information of the obstacle to the center 200 through the communication unit 120 when the position of the obstacle is specified.

At this time, the control unit 140 may receive a trigger command for triggering the shooting. The trigger command may be input when a brake pedal is depressed, when a voice command is input, when a command through a button operation is input while the vehicle is running, or the like.

In order to determine the position of the obstacle, the control unit 140 may correct the position of the obstacle through the side and rear cameras in addition to the movement of the steering wheel or the front camera.

It is assumed that the control unit 140 is equipped with a module for recognizing an obstacle on the road (e.g., a parchment).

The center 200 receives obstacle information from the electronic system 100. When the center 200 receives obstacle information from a plurality of vehicles over a predetermined number of times for a specific point, the center 200 can determine that the specific point is a place where the obstacle is located.

In this case, the center 200 transmits the obstacle information to the trailing vehicle for driving the specific point. The center 200 may transmit the obstacle information to the vehicle that has been set to navigate to the specific point.

The center 200 may transmit the lane information in which the obstacle is located together with the obstacle information. The center 200 can receive the lane information from the preceding vehicle and provide it to the trailing vehicle.

Hereinafter, a driving method of an electronic system for recognizing an obstacle will be described with reference to FIG. 3 will be referred to together.

First, the electronic system 100 mounted on the vehicle receives a shooting trigger command during driving (S410).

The electronic system 100 may include at least one photographing unit as described above, and at least one photographing unit may perform photographing according to a photographing trigger command. The shooting trigger command may include a brake pedal depressed, a voice recognition command (e.g., "take a picture" by the driver), and a user operation command in response to a specific button input.

The electronic system 100 may receive the GPS information of the current vehicle from the navigation system 50 when the photographing trigger command is input (S420).

Then, the electronic system 100 can photograph the vehicle front, side, and rear through a plurality of photographing units (S420).

The electronic system 100 recognizes an obstacle in the photographed image (S430).

For example, the electronic system 100 recognizes an obstacle in an image input through a front camera. It is assumed that the obstacle recognition method employs one of known recognition methods.

Next, the electronic system 100 receives the map information from the navigation system 50, analyzes the camera image, and determines the lane position (S440, S450). Through this step, the electronic system 100 can obtain lane information on the road of the obstacle.

The electronic system 100 may perform the obstacle position correction in steps S460 and S470. Specifically, after recognizing the obstacle visually, the electronic system 100 can grasp the movement of the vehicle steering wheel, and correct the position of the parchment with the side camera.

For example, when the obstacle is deviated from the front camera, the electronic system 100 can photograph the obstacle with the side camera and correct the position of the obstacle in consideration of both the image captured by the front camera and the image captured by the side camera.

Also, the electronic system 100 can correct the position of the obstacle by measuring the movement of the steering wheel when the obstacle comes off the front camera. It is possible to determine the position of the perch on the road based on the motion value of the steering wheel. For example, when the steering wheel rotates to the left, an obstacle can be photographed through the right-side camera, and when the steering wheel rotates in the right direction, the obstacle can be photographed through the left camera. However, just moving the steering wheel can help to recognize the position of the obstacle.

Then, the electronic system 100 transmits the obstacle location information to the center 200 (S480).

The center 200 receives and processes the obstacle information will be described with reference to FIG.

The center 200 may receive the obstacle location and the photograph information from the preceding vehicles that have passed the specific point first (S510).

The center 200 compares the obstacle previous position data (S520).

For example, the center 200 can determine the same specific point when receiving the previous data and the GPS signal within (+) (-) 10 meters, but it is not limited thereto.

When it is determined that the obstacle has not existed before, the center 200 stores the new obstacle location information (S540).

If the obstacle is previously received, the center 200 increments the number of times of transmission of the obstacle position information at the currently received specific position by one (S530). If the number of times of reception of the obstacle position information exceeds three times, To the following vehicle (S560).

Here, if the number of obstacle location information transmissions is three or less, the center 200 may wait to receive obstacle information again.

6 is a flowchart showing an electronic system mounted on a trailing vehicle that is provided with obstacle information;

First, when the trailing vehicle receives a message indicating that the obstacle is near (e.g., 30 meters) from the center in the running (S610), the trailing vehicle drives the plurality of photographing sections to photograph the front / rear / left / From the navigation device 50 (S620).

The electronic system of the trailing vehicle confirms the obstacle through the front camera (S625).

If the electronic system of the trailing vehicle is identified as an obstacle (S630), the obstacle lane information is compared (S645).

At this time, when it is determined that the electronic system of the trailing vehicle has changed the lane of the obstacle, it can be determined that the position of the obstacle is changed according to the external environment. In this case, the changed obstacle location information should be transmitted to the center. The process corresponds to S650 to S670.

If the lane is not changed first, the obstacle location information and the image can be transmitted to the center 200.

If it is determined that the lane has been changed, the electronic system receives the navigation MAP information and confirms the road lane information while driving on the photographed image (S650). Next, the camera image is analyzed to confirm the lane position.

Then, the steering wheel movement analysis is performed, and the specific obstacle position information is updated through the side camera image (S660, S665) and transmitted to the center 200. [

7 is a view showing a navigation screen provided by the trailing vehicle electronic system.

According to Fig. 7 (a), the electronic system of the trailing vehicle provides the guidance service.

For example, the electronic system of the trailing vehicle can receive information from the center 200 that the falling object is on a three-lane forward line of 20 meters and display it on the navigation screen.

Further, it may be indicated by a lane mark 710 that there is an obstacle in the corresponding three lanes.

The trailing vehicle's electronic system may be guided to the absence of obstacles when searching for a destination.
