Abstract
(EN)
A pitch angle acquisition unit acquires the pitch angle of a vehicle body. A blade position calculation unit calculates the position of a blade using the vehicle body as a reference. A travel direction specification unit specifies the travel direction of the vehicle body on the basis of the pitch angle and the position of the blade.
(FR)
Selon l'invention, une unité d'acquisition d'angle de tangage acquiert l'angle de tangage d'une carrosserie de véhicule. Une unité de calcul de position de lame calcule la position d'une lame en utilisant la carrosserie de véhicule en tant que référence. Une unité de spécification de direction de déplacement spécifie la direction de déplacement de la carrosserie de véhicule en se basant sur l'angle de tangage et la position de la lame.
(JA)
ピッチ角取得部は、車体のピッチ角を取得する。ブレード位置算出部は、車体を基準としたブレードの位置を算出する。進行方向特定部は、ピッチ角およびブレードの位置に基づいて、車体の進行方向を特定する。
