CONTROL APPARATUS, RADAR DETECTION SYSTEM, AND RADAR DETECTION METHOD
First Claim
1. A control apparatus comprising:
- a radar detection storage unit which stores information of radar detection;
an acquisition unit which acquires coordinates of a detection starting position and coordinates of a detection ending position detected by a radar, for each of a plurality of moving vehicles moving in a moving direction on a road, the radar provided so as to have a detection area in the moving direction on the road;
a calculation unit which calculates an average value of the coordinates of the detection starting positions acquired by the acquisition unit and an average value of the coordinates of the detection ending positions acquired by the acquisition unit and which stores the information of radar detection including the calculated average values in the radar detection storage unit;
a comparison unit which compares the average value of the coordinates of the detection starting positions indicated by the information of radar detection stored in the radar detection storage unit with a determined reference value for the detection starting positions and which compares the average value of the coordinates of the detection ending positions indicated by the information of radar detection stored in the radar detection storage unit with a determined reference value for the detection ending positions; and
an abnormality determination unit which determines on the basis of results of the comparisons by the comparison unit whether or not an abnormality has occurred in the radar.

Abstract
In a control apparatus, an acquisition unit acquires the coordinates of a detection starting position and detection ending position detected by a radar, for each of a plurality of moving vehicles moving along a road. A calculation unit calculates an average value of the coordinates of the detection starting positions and an average value of the coordinates of the detection ending positions, and stores information of radar detection including the calculated average values in a radar detection storage unit. A comparison unit compares the average values of the coordinates of the detection starting positions and detection ending positions with respective determined reference values. An abnormality determination unit determines based on the comparison results whether or not an abnormality has occurred in the radar, and outputs, if determining that an abnormality has occurred, information indicative of the occurrence of the abnormality.
