Warning condition adjusting apparatus and method

1. A warning condition adjusting apparatus comprising:

a determination unit configured to determine whether a parking direction of an ego vehicle is a first direction or a second direction, using traveling information of a target vehicle; and

a change unit configured to maintain a preset warning condition of a rear cross collision warning (RCCW) system when the parking direction of the ego vehicle is the first direction, and change the warning condition of the RCCW system when the parking direction of the ego vehicle is the second direction, which is different from the first direction.

2. The warning condition adjusting apparatus of claim 1 , wherein the determination unit determines the parking direction of the ego vehicle by comparing a preset reference axis to a radar axis generated through a radar signal reflected from the target vehicle in response to a radar signal transmitted from a radar sensor installed in the ego vehicle.

3. The warning condition adjusting apparatus of claim 2 , wherein the determination unit determines that the parking direction of the ego vehicle is the first direction, when the comparison result indicates that the radar axis is similar to the reference axis, and determines that the parking direction of the ego vehicle is the second direction, when the comparison result indicates that the radar axis is different from the reference axis.

4. The warning condition adjusting, apparatus of claim 3 , further comprising a compensation unit configured to calculate an entry angle at which the ego vehicle enters a parking space in the second direction, with respect to the reference axis, and compensate for detection information of the ego vehicle, included in the warning condition of the RCCW system, by the entry angle.

5. A warning condition adjusting method comprising:

determining, by a determination unit, Whether a parking direction of an ego vehicle is a first direction or a second direction, using traveling information of a target vehicle; and

maintaining, by a change unit, a preset warning condition of an RCCW system when the parking condition of the ego vehicle is the first direction, and changing the warning condition of the RCCW system when the parking direction of the vehicle is the second direction, which is different from the first direction.

6. The warning condition adjusting method of claim 5 , wherein the determining of whether the parking direction of the ego vehicle is the first or second direction comprises:

comparing a preset reference axis to a radar axis generated through a radar signal reflected from the target vehicle in response to a radar signal transmitted from a radar sensor installed in the ego vehicle; and

determining the parking direction of the ego vehicle according to the comparison result of the comparing of the preset reference axis to the radar axis.

7. The warning condition adjusting method of claim 6 , wherein the determining of the parking direction of the ego vehicle comprises:

determining that the parking direction of the ego vehicle is the first direction, when the radar axis and the reference axis are similar to each other, and

determining that the parking direction of the ego vehicle is the second direction, when the radar axis and the reference axis are different from each other.

8. The warning condition adjusting method of claim 7 , further comprising:

calculating, by a compensation unit, an entry angle at which the ego vehicle enters a parking space in the second direction, with respect to the reference axis; and

compensating for, by the compensation unit, detection information of the ego vehicle, included in the warning condition of the RCCW system, by the entry angle.

9. A computer program stored in a computer readable recording medium to execute the method of claim 5 , using a computer.
