Title
(EN) VEHICLE ENCOUNTER DETERMINATION APPARATUS
(FR) APPAREIL DE DÉTERMINATION DE RENCONTRE DE VÉHICULES
(JA) 遭遇車両判定装置
Abstract
(EN)
Provided is a vehicle encounter determination apparatus comprising the following: an own-vehicle intersection entering probability estimation unit (33) that estimates the probability of the own-vehicle entering an own-vehicle intersection in an own-vehicle path on a map; a different-vehicle intersection extraction unit (35) that, on the basis of vehicle information acquired from a different-vehicle using vehicle-to-vehicle communication, extracts an intersection of the different-vehicle on a path travelling towards the own-vehicle path, the different-vehicle matching any of the own-vehicle path and a connection road in a constant range which connects to the own-vehicle intersection; a different-vehicle intersection entering probability estimation unit (36) that estimates the probability of entering the extracted different-vehicle intersection; an encounter probability calculation unit (37) that calculates the probability of the own-vehicle and the different-vehicle encountering each other in the own-vehicle intersection, such calculation being made from the estimated probability of the own-vehicle entering the own-vehicle intersection and the estimated probability of the different-vehicle entering the different-vehicle intersection; and an encounter determination unit (38) for determining that a different-vehicle for which the calculated encounter probability is at least a threshold value is a different-vehicle that will encounter the own-vehicle.
(FR)
L'invention concerne un appareil de détermination de rencontre de véhicules comprenant les éléments suivants : une unité d'estimation de la probabilité de parvenir à un croisement du véhicule personnel (33) qui estime la probabilité du véhicule personnel à parvenir à un croisement du véhicule personnel lors d'un trajet du véhicule personnel sur une carte ; une unité d'extraction de croisement d'un autre véhicule (35) qui, sur la base d'informations de véhicule acquises d'un autre véhicule à l'aide d'une communication de véhicule à véhicule, extrait un croisement de l'autre véhicule sur un trajet allant vers le trajet du véhicule personnel, l'autre véhicule s'adaptant soit au trajet du véhicule personnel, soit à un itinéraire de liaison selon une autonomie constante qui rejoint le point de croisement du véhicule personnel ; une unité d'estimation de la probabilité de parvenir à un croisement d'un autre véhicule (36) qui estime la probabilité de parvenir au croisement extrait d'un autre véhicule ; une unité de calcul de probabilité de rencontre (37) qui calcule la probabilité que le véhicule personnel et l'autre véhicule se rencontrent lors du croisement du véhicule personnel, un tel calcul étant réalisé à partir de la probabilité estimée du véhicule personnel de parvenir au croisement du véhicule personnel et de la probabilité estimée d'un autre véhicule de parvenir au croisement d'un autre véhicule ; et une unité de détermination de rencontre (38) destinée à déterminer qu'un autre véhicule pour lequel la probabilité de rencontre calculée est au moins une valeur de seuil, est un autre véhicule qui rencontrera le véhicule personnel.

 遭遇車両判定装置(apparatus)は、地図上での自車進路における自車交叉点への自車の進入確率を推定する自車交叉点進入確率推定部(33)と、車車間通信で他車から取得した車両情報をもとにして、自車進路と自車交叉点に接続する一定範囲の接続道路とのいずれかにマッチングされる他車について、自車進路に向かって走行する進路上の他車交叉点を抽出する他車交叉点抽出部(35)と、抽出した他車交叉点への進入確率を推定する他車交叉点進入確率推定部(36)と、推定した自車交叉点への自車の進入確率と他車交叉点への他車の進入確率とから、自車交叉点での自車と他車との遭遇確率を算出する遭遇確率算出部(37)と、算出した遭遇確率が閾値以上となる他車を、自車と遭遇する他車と判定する遭遇判定部(38)とを備える。
