Abstract:
(EN) A radar system in which the characteristic of filter processing can be varied in consideration of the relative velocity of an object as well. A relative position and relative velocity with the object such as another vehicle, a pedestrian and on-road installation are measured by a measurement part. On the basis of the relative position and relative velocity with the object measured by the measurement part, a time until the object collides with a user's vehicle is calculated. On the basis of the calculated time, a filter coefficient for filter-processing a measured position obtained by converting the relative position of the measured object is varied. Thereby, the characteristic when filtering processing the measured position is varied between stability and response.
(FR) L'invention concerne un système radar utilisant une opération de filtrage dont il est possible de moduler la caractéristique en fonction de la vitesse relative d'un objet. L'invention consiste à mesurer par un moyen de mesure une position relative et une vitesse relative d'un objet, tel qu'un autre véhicule, un piéton ou une installation sur une route; à calculer en fonction de la position relative et de la vitesse relative de l'objet mesurées par le moyen de mesure un intervalle de temps séparant l'objet du véhicule d'un utilisateur; à modifier en fonction de l'intervalle de temps calculé un coefficient de filtrage associé au filtrage d'une position mesurée obtenu par conversion de la position relative de l'objet mesuré. L'invention permet donc de moduler la caractéristique de l'opération de filtrage de la position mesurée pour privilégier la stabilité ou la sensibilité.
(JA)  対象物の相対速度をも考慮して、フィルタ処理の特性を変化させることのできるレーダ装置を提供する。他車両、歩行者、及び路上設置物などの対象物との相対位置、及び相対速度を測定部で測定する。測定部で測定した対象物との相対位置、及び相対速度に基づいて当該対象物と自車両とが衝突するまでの時間を算出し、算出した時間に基づいて、測定した対象物の相対位置を変換した測定位置をフィルタ処理するときのフィルタ係数を変化させることによって、当該測定位置をフィルタ処理するときの特性を安定性と、応答性との間で変化させる。
