Abstract
A vehicle measurement station utilizing one or more displacement sensors disposed on each opposite side of an inspection region of a vehicle inspection lane to acquire displacement measurement data along associated measurement axes. At least a portion of the displacement measurement data is associated with the outermost wheel assemblies on an axle of a moving vehicle passing through the inspection region, and utilized to determine one or more vehicle characteristics, such as an axle total toe condition.
Claims5
A vehicle measurement system, comprising:
- a pair of sensor units disposed in proximity to a vehicle inspection lane through which a moving vehicle passes, with one sensor unit of said pair on each opposite lateral side of said vehicle inspection lane;
- a plurality of displacement sensors mounted within each sensor unit, each of said displacement sensors having at least one associated measurement axis, and each of said associated measurement axis oriented towards said vehicle inspection lane;
- wherein at least two of said plurality of displacement sensors within each sensor unit are horizontally displaced from each other;
- wherein each said plurality of displacement sensors is configured to acquire a plurality of distance measurements associated with points on surfaces of the moving vehicle intersecting said associated measurement axis as the vehicle moves through said vehicle inspection lane;
- wherein each of said plurality of displacement sensors is operatively coupled to convey said plurality of distance measurements to a processing system configured with software instructions to determine at least one vehicle characteristic from said conveyed distance measurements;
- and
- wherein said processing system is further configured to generate a report of said at least one vehicle characteristic.
