Abstract
A system for measuring the orientation angle of automotive collision avoidance sensors. An adaptive spacer is supported to conformably interengage the collision avoidance sensor module of a vehicle being repaired. The adaptive spacer extends outwardly from the sensor module and the orientation angle of the sensor module is transposed by the adaptive spacer to form an angular guideline on an underlying calibration board, mat or other surface. The angle between the angular guideline and a base guideline parallel to the center line of the vehicle and the angular guideline is measured to provide the orientation angle of the vehicle's sensor module.
Claims14
A system for measuring the horizontal angular inclination between an automotive collision avoidance sensor module and a longitudinal centerline of a motor vehicle to which the automotive collision avoidance sensor module is mounted, said system comprising:
- a calibration component disposed below the sensor module, said calibration component having a horizontal upper surface, said horizontal upper surface carrying a base guideline that is aligned with or parallel to the longitudinal centerline of the motor vehicle;
- a vertical support post engaging and extending upwardly from said horizontal upper surface of said calibration component;
- said vertical support post being positioned outwardly of the sensor module;
- a spacer component carried by said support post, said spacer component having an inner end configured for engaging an outer surface of the sensor module such that the spacer component extends outwardly from the sensor module to said support post;
- said support post having a longitudinal side that is parallel to and spaced outwardly of the outer face of the sensor module, said longitudinal side of said support post defining an angular guideline at a lower end of said support post on said calibration component, said angular guideline being extendable across said horizontal surface of said calibration component to intersect said base guideline at a horizontal angular inclination that matches the horizontal angular inclination between the automotive collision avoidance sensor module and the longitudinal centerline of the motor vehicle;
- and
- an angle measuring gauge for engaging the base guideline and the angular guideline to determine the angle at which the angular guideline intersects the base guideline and the matching horizontal angular inclination between the sensor module and the centerline of the motor vehicle.
