Title
(EN) MOBILE VEHICULAR ALIGNMENT FOR SENSOR CALIBRATION
(FR) ALIGNEMENT DE VÉHICULE POUR ÉTALONNAGE DE CAPTEUR
Abstract
(EN)
A mobile system and method of calibrating an ADAS sensor (30) of a vehicle (22) by aligning a target (26) with the sensor (30), where a transport vehicle (21) is equipped with a target adjustment stand (24) for transporting to the vehicle (22), which includes a movable target mount (124) configured to support a target (26), with the target adjustment stand (24) including one or more actuators (31, 104, 112, 120, 126) for adjusting the position of the target mount (124). A computer system (42, 170) is used to determine an orientation of the vehicle (22) relative to the target adjustment stand (24), with the position of the target mount (124) being adjusted based on the determined orientation of the vehicle (22) relative to the target adjustment stand (24). Upon properly orienting the target (26), a calibration routine is performed whereby sensor (30) is calibrated using target (26).

L'invention concerne un système et un procédé d'étalonnage d'un capteur de système d'aide à la conduite (30) d'un véhicule (22) par alignement d'une cible (26) avec le capteur (30), dans lequel un véhicule de transport (21) est équipé d'un socle d'ajustement de cible (24) servant à transporter le véhicule (22), qui comprend un support de cible mobile (124) configuré pour supporter une cible (26), le socle d'ajustement de cible (24) comprenant un ou plusieurs actionneurs (31, 104, 112, 120, 126) pour ajuster la position du support de cible mobile (124). Un système informatique (42, 170) est utilisé pour déterminer l'orientation du véhicule (22) par rapport au socle d'ajustement de cible (24), la position du support de cible mobile (124) étant réglée sur la base de l'orientation déterminée du véhicule (22) par rapport au socle d'ajustement de cible (24). Lors de l'orientation correcte de la cible (26), une routine d'étalonnage est effectuée, au cours de laquelle le capteur (30) est étalonné à l'aide de la cible (26).
