Abstract
(EN)
A driving assistance device (10), wherein a required starting space estimating unit (12) estimates a required starting space, which is the space required by a host vehicle for completion of starting. A required starting time estimating unit (14) calculates an estimated required starting time, which is an estimated value of the time required for completion of starting during starting of the host vehicle. A collision time estimating unit (13) calculates an estimated collision time, which is an estimated value of the time until an obstacle reaches the required starting space. A starting margin calculating unit (15) calculates a starting margin on the basis of the estimated required starting time and the estimated collision time, the starting margin indicating a temporal margin for completing the starting of the host vehicle by the time the obstacle reaches the required starting space. A notification processing unit (16) notifies the driver of the host vehicle of the starting margin.

L'invention concerne un dispositif d'assistance à la conduite (10), dans lequel une unité d'estimation d'espace de démarrage requis (12) estime un espace de démarrage requis, qui est l'espace requis par un véhicule hôte pour mener à bien le démarrage. Une unité d'estimation de temps de démarrage requis (14) calcule un temps de démarrage requis estimé, qui est une valeur estimée du temps requis pour mener à bien le démarrage pendant le démarrage du véhicule hôte. Une unité d'estimation de temps de collision (13) calcule un temps de collision estimé, qui est une valeur estimée du délai jusqu'à ce qu'un obstacle atteigne l'espace de démarrage requis. Une unité de calcul de marge de démarrage (15) calcule une marge de démarrage sur la base du temps de démarrage requis estimé et du temps de collision estimé, la marge de démarrage indiquant une marge temporelle pour mener à bien le démarrage du véhicule hôte par le délai d'atteinte par l'obstacle de l'espace de démarrage requis. Une unité de traitement de notification (16) notifie au conducteur du véhicule hôte la marge de démarrage.

運転支援装置(10)において、発進所要空間推定部(12)は、発進完了のために自車両が必要とする空間である発進所要空間を推定する。発進所要時間推定部(14)は、自車両の発進時に、発進完了までに要する時間の推定値である推定発進所要時間を算出する。衝突時間推定部(13)は、障害物が発進所要空間に達するまでの時間の推定値である推定衝突時間を算出する。発進余裕度算出部(15)は、推定発進所要時間および推定衝突時間に基づいて、自車両の発進を障害物が発進所要空間に達するまでに完了させる時間的余裕を示す発進余裕度を算出する。通知処理部(16)は、発進余裕度を自車両の運転者に通知する。
