Abstract
(EN)
A travel track creation device (2) includes a travel track creator (42) that creates a travel track including an inlet straight track, an inlet clothoid track formed by connecting a first group of clothoid curves, an arc track, an outlet clothoid track formed by connecting a second group of clothoid curves, and an outlet straight track, wherein the travel track creator (42) includes an arc creator (42a) that creates the arc track which is located further on a side opposite to the center side of the arc portion than a passing target point and a radius of which is as large as possible, the passing target point being separated from an inner edge of the arc portion by a predetermined distance toward the side opposite to the center side of the arc portion, and a clothoid creator (42b) that creates the inlet clothoid track in which a radius of a last tangential arc corresponds to a radius of the arc track and a start point of which is in contact with the inlet straight track and in which a direction angle of the start point corresponds to a direction angle of the inlet straight track, and the outlet clothoid track in which a radius of a last tangential arc corresponds to a radius of the arc track and which is in contact with the outlet straight track and in which a direction angle of a start point corresponds to a direction angle of the outlet straight track.

(FR)
Dispositif de préparation de trajectoire de déplacement (2) pourvu d'une unité de préparation de trajectoire de déplacement (42) pour préparer une trajectoire de déplacement qui comprend une section d'approche linéaire, une section d'approche clothoïde dans laquelle un premier groupe de courbes clothoïdes sont reliées, une section d'arc, une section de clothoïde d'échappement dans laquelle un deuxième groupe de courbes clothoïdes sont reliées, et une section d'échappement linéaire, l'unité de préparation de trajectoire de déplacement (42) comprenant : une unité de préparation d'arc (42a) pour préparer une section d'arc qui est positionnée plus près du côté anticentre d'un intervalle d'arc qu'un point cible de passage qui est séparé d'une distance prédéfinie sur le côté anticentre de l'intervalle d'arc par rapport au bord intérieur de l'intervalle d'arc, la section d'arc ayant un rayon aussi grand que possible; et une unité de préparation de clothoïde (42b) pour préparer une section d'approche clothoïde ayant le rayon de la section d'arc comme rayon d'un arc tangentiel final, le point de départ étant en contact avec la section d'approche linéaire, et l'angle de direction de la section d'approche linéaire étant utilisé comme angle de direction du point de départ, et une section de clothoïde d'échappement ayant le rayon de la section d'arc comme rayon d'un arc tangentiel final, étant en contact avec la section d'échappement linéaire, et ayant l'angle de direction de la section d'évacuation linéaire comme angle de direction du point de départ.
