Appl. No.:

16/926664

International Classification:

G01B 11/275

Abstract:

A system and method for aligning a target to a vehicle for calibration of a sensor equipped on the vehicle includes multiple non-contact wheel alignment sensors configured for use in determining the orientation of tire and wheel assemblies of the vehicle. A target adjustment frame includes a target mount moveably mounted on a base frame, and includes multiple actuators configured to selectively move the target mount relative to the base frame, where the base frame is in a known orientation to the non-contact wheel alignment sensors. A computer system selectively actuates the actuators to position a target relative to the vehicle, with the target mount being moveable about a plurality of axes based on the determination of the orientation of the vehicle relative to the target adjustment frame to position the target relative to a sensor of the vehicle whereby the sensor is able to be calibrated using the target.

International Classification:

G01B 11/275

Abstract:

A mobile system and method of calibrating an ADAS sensor of a vehicle by aligning a target with the sensor, where a transport vehicle is equipped with a target adjustment stand for transporting to the vehicle, which is initially nominally positioned in front of the target adjustment stand that includes a movable target mount configured to support a target, with the target adjustment stand including one or more actuators for adjusting the position of the target mount. A computer system is used to determine an orientation of the vehicle relative to the target adjustment stand, with the position of the target mount being adjusted based on the determined orientation of the vehicle relative to the target adjustment stand. Upon properly orienting the target mount, and the target supported thereon, a calibration routine is performed whereby the sensor is calibrated using the target.

Abstract:

A system and method of calibrating an ADAS sensor of a vehicle by aligning a target with the sensor, where the vehicle is initially nominally positioned in front of a target adjustment stand that includes a stationary base frame and a movable target mount configured to support a target, with the target adjustment stand including one or more actuators for adjusting the position of the target mount. A computer system is used to determine an orientation of the vehicle relative to the target adjustment stand, with the position of the target mount being adjusted based on the determined orientation of the vehicle relative to the target adjustment stand. Upon properly orienting the target mount, and the target supported thereon, a calibration routine is performed whereby the sensor is calibrated using the target.
