3. The anti-collision control device of claim 1 , wherein the processor determines that the neighboring vehicle intends to change lanes when the horizontal separation distance is calculated to be less than or equal to a predetermined reference warning distance.

4. The anti-collision control device of claim 3 , wherein the processor determines that the neighboring vehicle intends to change lanes when a state in which the horizontal separation distance is calculated to be less than or equal to the predetermined reference warning distance is continued during a predetermined period of time.

5. The anti-collision control device of claim 1 , wherein the processor determines whether the neighboring vehicle intends to change lanes by further using lighting information associated with a blinker of the neighboring vehicle, which is sensed by a camera sensor.

6. The anti-collision control device of claim 1 , wherein, when it is determined that the neighboring vehicle intends to change lanes to the lane in which the vehicle drives, processor identifies the existence of an area that overlaps the location of the vehicle when the neighboring vehicles enters the lane, and determines the risk of collision.

7. The anti-collision control device of claim 1 , wherein, when it is determined that the risk of collision exists, the processor outputs the warning control signal such that a warning signal is generated via a display device or a sound device of the vehicle, or outputs the warning control signal such that collision warning information is transmitted to the neighboring vehicle via an inter-vehicle communication device.

8. The anti-collision control device of claim 1 , wherein, when it is determined that the risk of collision exists, the processor outputs the movement control signal for controlling steering and speed of the vehicle such that the vehicle moves along the collision-free path.

9. The anti-collision control device of claim 1 , the processor is further configured to determine initiation of operation of an anti-collision control mode,

wherein the processor calculates the horizontal separation distance when the anti-collision control mode is initiated.

10. The anti-collision control device of claim 9 , wherein the processor determines initiation of operation of the anti-collision control mode when the vehicle exists in a blind spot of the neighboring vehicle, and

the blind spot of the neighboring vehicle is calculated based on at least one from among height information of the neighboring vehicle, length information of the neighboring vehicle, location information of the neighboring vehicle, location information of the vehicle, and model information of the neighboring vehicle.

11. The anti-collision control device of claim 10 , wherein the processor determines a blind spot size corresponding to the neighboring vehicle using a plurality of pieces of blind spot size information which are previously stored in accordance with at least one piece of information from among the height information of the neighboring vehicle, the length information of the neighboring vehicle, and the model information of the neighboring vehicle, and

the blind spot of the neighboring vehicle is calculated based on the blind spot size and the location information of the neighboring vehicle.

12. The anti-collision control device of claim 9 , wherein the processor determines initiation of operation of the anti-collision control mode when the neighboring vehicle enters a blind spot detection area of the vehicle.

13. An anti-collision control method, comprising:

calculating a horizontal separation distance between a vehicle and a neighboring vehicle that drives in a lane next to a lane in which the vehicle drives;

detecting an intention to change lanes of the neighboring vehicle using separation distance information;

calculating a risk of collision of the vehicle based on at least one piece of information from among lane change intention information of the neighboring vehicle, location information of the neighboring vehicle, location information of the vehicle, and relative speed information of the vehicle and the neighboring vehicle;

outputting a movement control signal or a warning control signal for the vehicle based on a result of calculating the risk of collision of the vehicle; and

comparing distance information calculated by each distance measuring sensor among two or more distance measuring sensors installed on one lateral side of the vehicle, and calculating a collision-free path of the vehicle based on location information of a distance measuring sensor which approaches within a reference warning distance first.
