A procedure for calibrating a vehicle onboard sensorby facilitating the placement of a calibration fixtureon a floor relative to a stationary vehicleusing a laser emittersecured to a front steerable wheelof the vehicle on the same lateral side as the vehicle onboard sensor. A beam projection axis X of the laser projector is aligned at a known orientation relative to a geometric characteristic of the vehicle, such that the beam projection axis X is directed over a placement location P of the calibration fixture on the floor, either inherently or by guided steering of the supporting steerable wheel. A distance between the calibration fixtureand a reference point associated with the vehicleis measured, and a current position of the calibration fixture on the floor along the beam projection axis X is adjusted as required to position the calibration fixture for calibration of the vehicle sensorat a selected distance from the reference point along the beam projection axis X.

Method and apparatus for alignment of vehicle blind spot monitoring sensor

A vehicle wheel service system configured with a load roller assembly to apply a generally radial load to a vehicle wheel assembly during rotation, and which is configured with sensors to obtain one or more measurements of lateral forces associated with the vehicle wheel assembly during the loaded rotation, from which a quantified representation of lateral force for the tire of the vehicle wheel assembly is determined.
