Abstract
A system and method of calibrating an ADAS sensor of a vehicle by aligning a target with the sensor using a target adjustment stand that includes a 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. The position of the target mount is adjusted based on the 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.
Claims7
A system for aligning a target to a vehicle for calibration of a sensor equipped on the vehicle, said system comprising:
- a vehicle stand upon which a vehicle is configured to be positioned;
- a target adjustment frame movably mounted to a rail with said rail extending longitudinally with respect to said vehicle stand and to a longitudinal axis of the vehicle when positioned on said vehicle stand, said target adjustment frame including a base frame movably mounted to said rail, a target mount moveably mounted on said target adjustment frame with said target mount configured to support a target, said target adjustment frame further including a plurality of actuators configured to selectively move said target mount relative to said base frame;
- a computer system, said computer system configured to selectively actuate said actuators to position said target relative to the vehicle positioned in front of said target adjustment frame, with said target mount being moveable by said actuators vertically and laterally with respect to the longitudinal axis of the vehicle when positioned in front of said target adjustment frame;
- wherein said target adjustment frame is moved on said rail into a longitudinal orientation relative to the vehicle and said computer system selectively actuates said actuators to position said target based on a known orientation of the vehicle on said vehicle stand to position said target relative to a sensor of the vehicle whereby the sensor is able to be calibrated using the target.
