Title
(EN) AXIAL DEVIATION ESTIMATION DEVICE
(JA) 軸ずれ推定装置
Abstract
(EN)

PROBLEM TO BE SOLVED: To improve the accuracy in estimating an axial deviation angle.

SOLUTION: A processing unit 60 repeatedly calculates an axial deviation angle based on a detection result by a radar system 1. The processing unit 60 extracts an axial deviation angle included in a preset extraction angle range from among a plurality of calculated axial deviation angles, and calculates an average of a plurality of extracted axial deviation angles as an axial deviation angle average. The processing unit 60 determines whether a preset adoption condition is satisfied based on the axial deviation angle average. The processing unit 60 adopts the calculated axial deviation angle average as an estimation result of the axial deviation angle when it is determined that the adoption condition is satisfied.

【課題】軸ずれ角度の推定精度を向上させる。
【解決手段】処理ユニット60は、レーダ装置1による検出結果に基づいて軸ずれ角度を繰り返し算出する。処理ユニット60は、算出された複数の軸ずれ角度のうち、予め設定された抽出角度範囲に含まれる軸ずれ角度を抽出し、抽出された複数の軸ずれ角度の平均値を軸ずれ角度平均値として算出する。処理ユニット60は、軸ずれ角度平均値に基づいて、予め設定された採用条件が成立したか否かを判断する。処理ユニット60は、採用条件が成立したと判断した場合に、算出された軸ずれ角度平均値を、軸ずれ角度の推定結果として採用する。
