Title (EN) A SYSTEM FOR ENHANCED OBJECT TRACKING
(FR) SYSTÈME POUR L'AMÉLIORATION DU PISTAGE D'UN OBJET
Abstract:
(EN) The present disclosure relates to a vehicle radar system (3) comprising a control unit arrangement (8) and at least one radar sensor arrangement (4) that is arranged to transmit signals (6) and receive reflected signals (7). The vehicle radar system (3) is arranged to acquire a plurality of measured radar detections (10, 11, 12, 13) at different times. The control unit arrangement (8) is arranged to engage a tracking algorithm using the present measured radar detections (10, 11, 12, 13) as input such that at least one track is initialized. For each track, the control unit arrangement (8) is arranged to calculate a calculated previous radar detection (14) that precedes the present measured radar detections (10, 11, 12, 13), and to re-initialize the tracking algorithm using the present measured radar detections (10, 11, 12, 13) in combination with the calculated previous radar detection (14).
(FR) La présente invention concerne un système radar de véhicule (3) comprenant un agencement d'unité de commande (8) et au moins un agencement de capteur radar (4) qui est conçu pour émettre des signaux (6) et recevoir des signaux réfléchis (7). Le système radar de véhicule (3) est conçu pour acquérir une pluralité de détections radar mesurées (10, 11 12, 13) à différents moments. L'agencement d'unité de commande (8) est conçu pour coopérer avec un algorithme de pistage en utilisant les présentes détections radar mesurées (10, 11 12, 13) comme entrée, de façon qu'au moins un pistage soit initialisé. Pour chaque pistage, l'agencement d'unité de commande (8) est conçu pour calculer une détection radar précédemment calculée (14) qui précède les présentes détections radar mesurées (10, 11, 12, 13), et pour réinitialiser l'algorithme de pistage à l'aide des présentes détections radar mesurées (10, 11 12, 13) en combinaison avec la détection radar précédemment calculée (14).
