Abstract

A sameness judgment unit of an object recognition apparatus sets a threshold value for a relative distance between the first object and the second object, for judging whether or not the first object and the second object are the same. If at least a portion of the first object exists on a travel path of a vehicle, and the second object exists outside of the travel path, the sameness judgment unit judges that the first object and the second object are different objects, even if the relative distance is less than or equal to the threshold value.

First claim

What is claimed is:

1. An object recognition apparatus comprising:
a camera configured to detect a first object existing in a traveling direction of a vehicle;
a radar configured to detect a second object existing in the traveling direction; and
a processor configured to provide a sameness judgment unit configured to judge whether the first object and the second object are the same, by comparing a position of the first object and a position of the second object;
wherein:
the sameness judgment unit sets a threshold value for a relative distance between the first object and the second object, for judging whether or not the first object and the second object are the same;
if at least a portion of the first object exists on a travel path of the vehicle, and the second object exists outside of the travel path, the sameness judgment unit judges that the first object and the second object are different objects, even if the relative distance is less than or equal to the threshold value, and
in response to the judgment of the sameness judgment unit, the processor is further configured to execute driving support including at least one of velocity control, stability assist control, collision mitigation brake control, and steering assist control.

2. The object recognition apparatus according to claim 1 , wherein if the camera has detected at least a portion of the first object on the travel path, and the second object outside of the travel path and the second object on the travel path, for which the relative distances thereof, respectively, with the first object are less than or equal to the threshold value, are detected, the processor executes the driving support with respect to the second object on the travel path, even if the relative distance of the second object outside of the travel path is shorter than that of the second object on the travel path.

3. The object recognition apparatus according to claim 1 , wherein if the camera has detected at least a portion of the first object on the travel path, and the radar has detected the second object outside of the travel path, for which the relative distance thereof with the first object is less than or equal to the threshold value, and the second object on the travel path, for which the relative distance with the first object is not less than or equal to the threshold value, the processor executes the driving support with respect to the second object on the travel path.

4. The object recognition apparatus according to claim 1 , wherein if the camera has detected at least a portion of the first object on the travel path, and the second object outside of the travel path and the second object on the travel path, for which the relative distances thereof, respectively, with the first object are less than or equal to the threshold value, are detected, the sameness judgment unit determines that the first object and the second object on the travel path are the same, even if the relative distance of the second object outside of the travel path is shorter than that of the second object on the travel path.

5. The object recognition apparatus according to claim 1 , wherein if the camera has detected at least a portion of the first object on the travel path, and the radar has detected the second object outside of the travel path, for which the relative distance thereof with the first object is less than or equal to the threshold value, and the second object on the travel path, for which the relative distance with the first object is not less than or equal to the threshold value, the sameness judgment unit determines that the first object and the second object on the travel path are the same.
