Title
(EN) AXIAL MISALIGNMENT ESTIMATION DEVICE
(FR) DISPOSITIF D'ESTIMATION DE DÉSALIGNEMENT AXIAL
(JA) 軸ずれ推定装置
Abstract
(EN) An axial misalignment estimation device (60) repeatedly calculates axial misalignment angles on the basis of detection results from a radar device (1). From a plurality of calculated misalignment angles, the axial misalignment estimation device extracts axial misalignment angles included in a preset extracted angle range, and calculates the average value of the plurality of extracted axial misalignment angles as an axial misalignment angle average value. On the basis of the axial misalignment angle average value, the axial misalignment estimation device determines whether or not preset adoption conditions have been satisfied. If the adoption conditions are determined to have been satisfied, the axial misalignment estimation device adopts the calculated axial misalignment angle average value as axial misalignment angle estimation results.
(FR) Dispositif d'estimation de désalignement axial (60) calculant de manière répétée des angles de désalignement axial sur la base de résultats de détection provenant d'un dispositif radar (1). Parmi une pluralité d'angles de désalignement calculés, le dispositif d'estimation de désalignement axial extrait des angles de désalignement axial inclus dans une plage d'angle extraite prédéfinie et calcule la valeur moyenne de la pluralité d'angles de désalignement axial extraits en tant que valeur moyenne d'angle de désalignement axial. Sur la base de la valeur moyenne d'angle de désalignement axial, le dispositif d'estimation de désalignement axial détermine si des conditions d'adoption prédéfinies ont été satisfaites ou non. Si les conditions d'adoption sont déterminées comme ayant été satisfaites, le dispositif d'estimation de désalignement axial adopte la valeur moyenne d'angle de désalignement axial calculée en tant que résultats d'estimation d'angle de désalignement axial.
(JA) 軸ずれ推定装置(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。軸ずれ推定装置は、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。軸ずれ推定装置は、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。軸ずれ推定装置は、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。
