Abstract
(EN)
Provided is an object detection device for a vehicle, which makes it possible for the spatial location of an obstacle to be accurately judged. At least two ultrasonic sensors (21a, 21b) for example are arranged as distance measurement units, and based on the distance to an object which is measured before and after a vehicle moves directly ahead, and the movement distance when the vehicle moves directly ahead which is measured by a movement distance acquisition unit (wheel speed sensor (22)) that detects the movement distance of the vehicle, the spatial location of the obstacle which is detected from the geometric relationship of the distances is calculated.
(FR)
L'invention porte sur un dispositif de détection d'objet pour un véhicule, lequel dispositif rend possible d'estimer avec précision l'emplacement spatial d'un obstacle. Au moins deux capteurs d'ultrasons (21a, 21b), par exemple, sont disposés sous la forme d'unités de mesure de distance, et, sur la base de la distance par rapport à un objet qui est mesurée avant et après qu'un véhicule se déplace directement vers l'avant, et de la distance de déplacement quand le véhicule se déplace directement vers l'avant, qui est mesurée par une unité d'acquisition de distance de déplacement (capteur de vitesse de roue (22)) qui détecte la distance de déplacement du véhicule, l'emplacement spatial de l'obstacle qui est détecté à partir de la relation géométrique des distances est calculé.
