Abstract

Provided are a method and a device for controlling a vehicle approaching an intersection, and more particularly, a method and a device for controlling a vehicle approaching an intersection, which controls a vehicle approaching an intersection by selecting a traffic signal for the vehicle. The method of controlling a vehicle approaching an intersection includes: collecting traffic light information including signal cycles and positional coordinates of traffic lights installed at the intersection; selecting a corresponding traffic light among the traffic lights in consideration of positional information of the vehicle at the intersection and the positional coordinates of the traffic lights; and controlling the vehicle on the basis of the signal cycle of the corresponding traffic light.

Claims

1. A method of controlling a vehicle approaching an intersection, the method comprising:

collecting traffic light information including signal cycles and positional coordinates of traffic lights installed at the intersection;

selecting a corresponding traffic light among the traffic lights in consideration of positional information of the vehicle at the intersection and the positional coordinates of the traffic lights; and

controlling the vehicle on the basis of the signal cycle of the corresponding traffic light.

2. The method of claim 1, wherein the selecting the corresponding traffic light determines a travel direction on the basis of the positional information of the vehicle at the intersection and selects the corresponding traffic light among the traffic lights by matching the positional coordinates of the traffic lights with the travel direction of the vehicle in a coordinate plane.

3. The method of claim 2, wherein the corresponding traffic light is selected among traffic lights at the intersection in the travel direction.

4. The method of claim 2, wherein the corresponding traffic light is a traffic light farthest away from the vehicle among traffic lights at the intersection in the travel direction.

5. The method of claim 2, wherein the corresponding traffic light is a traffic light at left among traffic lights at the intersection in the travel direction.

6. The method of claim 1, wherein the controlling the vehicle starts or stops an engine of the vehicle on the basis of the signal cycle of the corresponding traffic light in order to prevent idling of the vehicle.

7. The method of claim 6, further comprising collecting signal lamp information of the vehicle,

wherein the controlling the vehicle starts or stops the engine of the vehicle in consideration of the signal lamp information and the signal cycle of the corresponding traffic light.

8. A device for controlling a vehicle approaching an intersection, the device comprising:

a traffic light information process unit that collects traffic light information including signal cycles and positional coordinates of traffic lights installed at the intersection;

a traffic light selecting unit that selects a corresponding traffic light among the traffic lights in consideration of positional information of the vehicle at the intersection and the positional coordinates of the traffic lights; and

a vehicle control unit that controls the vehicle on the basis of the signal cycle of the corresponding traffic light.

9. The device of claim 8, wherein the traffic light selecting unit determines a travel direction on the basis of the positional information of the vehicle at the intersection, and selects the corresponding traffic light among the traffic lights by matching the positional coordinates of the traffic lights with the travel direction of the vehicle in a coordinate plane.

10. The device of claim 9, wherein the traffic light selecting unit selects the corresponding traffic light among traffic lights at the intersection in the travel direction.

11. The device of claim 9, wherein the traffic light selecting unit selects a traffic light farthest away from the vehicle among traffic lights at the intersection in the travel direction as the corresponding traffic light.

12. The device of claim 9, wherein the traffic light selecting unit selects a traffic light at left among traffic lights at the intersection in the travel direction as the corresponding traffic light.

13. The device of claim 8, wherein the vehicle control unit starts or stops an engine of the vehicle on the basis of the signal cycle of the corresponding traffic light in order to prevent idling of the vehicle.

14. The device of claim 13, wherein the vehicle control unit collects the vehicle signal lamp information and starts or stops the engine of the vehicle in consideration of the signal cycle of the corresponding traffic light and the signal lamp information of the vehicle.
