Back-sideways alarming system for vehicle and alarming control method thereof
View Patent ↗Provided are a back-sideways alarming system and an alarming control method, which are capable of reducing the generation of a false alarm by detecting a driving road environment of a vehicle and preventing an unnecessary alarm caused by target information generated at a centerline of a road and an outside of a road. The back-sideways alarming system includes: an image acquiring unit configured to acquire road information of a vehicle; a collecting unit configured to collect target information on targets located around the vehicle; and an electronic control unit configured to recognize a lane based on the road information acquired by the image acquiring unit, reset an alarm area according to information on the recognized lane and the road information, and generate an alarm when the target information is located in the reset alarm area.
1. A back-sideways alarming system comprising:
an image acquiring unit configured to acquire road information of a vehicle;
a collecting unit configured to collect target information on one or more target vehicles or target objects located around the vehicle; and
an electronic control unit configured to recognize a lane based on the road information acquired by the image acquiring unit, generate an alarm when the one or more target vehicles or target objects located around the vehicle are located in a variably settable alarm area, and change the variably settable alarm area according to information on the recognized lane and the road information.
2. The back-sideways alarming system according to claim 1 , wherein the electronic control unit comprises:
a receiving unit configured to receive the road information acquired by the image acquiring unit and the target information collected by the collecting unit;
a determining unit configured to recognize a lane from the road information received by the receiving unit and analyze a color and shape of the recognized lane to determine on which lane the vehicle is running; and
an alarm area resetting unit configured to reset the variably settable alarm area by deleting a left alarm area of the vehicle when it is determined that the vehicle is running on a most left lane and deleting a right alarm area of the vehicle when it is determined that the vehicle is running on a most right lane.
3. The back-sideways alarming system according to claim 2 , wherein the electronic control unit comprises a target deleting unit configured to delete target information when the target information is collected from the deleted alarm area.
4. The back-sideways alarming system according to claim 1 , wherein when the target information entering the alarm area reset by the alarm area resetting unit is received, the electronic control unit outputs a preset alarm generation signal to an alarm generating unit.
5. The back-sideways alarming system according to claim 1 , wherein the electronic control unit comprises:
a receiving unit configured to receive the road information acquired by the image acquiring unit and the target information collected by the collecting unit;
a determining unit configured to recognize a lane from the road information received by the receiving unit and analyze a color and shape of the recognized lane to determine on which lane the vehicle is running; and
an alarm area resetting unit configured to reset the variable settable alarm area by deleting an alarm area disposed outside a centerline when it is determined that the vehicle is running on a first lane and deleting an alarm area disposed outside a last lane when it is determined that the vehicle is running on the last lane.
6. An alarming control method of a back-sideways alarming system, comprising:
receiving road information of a vehicle which is acquired by an image acquiring unit installed in the vehicle;
receiving target information on one or more target vehicles or target objects located around the vehicle, the target information being collected by an information collecting unit installed in the vehicle;
recognizing a lane based on the received road information;
changing a variably settable alarm area according to information on the recognized lane and the road information; and
generating an alarm when the one or more target vehicles or target objects located around the vehicle are located in the variably settable alarm area.
7. The alarming control method according to claim 6 , wherein the step of generating the alarm comprises:
recognizing a lane from the received road information and analyzing a color and shape of the recognized lane to determine on which lane the vehicle is running; and
resetting an alarm area by deleting a left alarm area of the vehicle when it is determined that the vehicle is running on a most left lane and deleting a right alarm area of the vehicle when it is determined that the vehicle is running on a most right lane.
8. The alarming control method according to claim 7 , further comprising, after the step of resetting the alarm area, deleting target information when the target information is collected from the deleted alarm area.
9. The alarming control method according to claim 6 , wherein the step of generating the alarm comprises outputting a preset alarm generation signal to an alarm generating unit when the target information entering the variably settable alarm area is received.
10. The alarming control method according to claim 6 , wherein the step of generating the alarm comprises:
recognizing a lane from the received road information and analyzing a color and shape of the recognized lane to determine on which lane the vehicle is running; and
resetting an alarm area by deleting an alarm area disposed outside a centerline when it is determined that the vehicle is running on a first lane and deleting an alarm area disposed outside a last lane when it is determined that the vehicle is running on the last lane.
11. The back-sideways alarming system of claim 1 , wherein the electronic control unit removes an area, which should not generate the alarm, from the variably settable area according to the information on the recognized lane and the road information.
12. The back-sideways alarming system of claim 1 , wherein the collecting unit comprises a radar.
13. The back-sideways alarming system of claim 1 , wherein the collecting unit collects the target information including at least one of a distance, an angle, a course angle and a relative speed with respect to the one or more target vehicles or target objects located around the vehicle.
14. The alarming control method according to claim 6 , wherein the changing the variably settable alarm area comprises removing an area, which should not generate the alarm, from the variable stable area according to the information on the recognized lane and the road information.
15. The alarming control method according to claim 6 , wherein the information collecting unit comprises a radar.
16. The alarming control method according to claim 6 , wherein the receiving the target information comprises collecting the target information including at least one of a distance, an angle, a course angle and a relative speed with respect to the one or more target vehicles or target objects located around the vehicle.
