An image processing type aligner enables proper set-up of one of two adjustment elements used to align an adaptive cruise control sensor or the like mounted on a vehicle. One element, such as a laser beam source, is mounted with the sensor on the vehicle; and the other element, such as a mirror, is mounted on a stand. A carrier on the stand positions at least one image sensor of the aligner system. The stand is positioned in front of the vehicle and manipulated until the aligner indicates that the axis of the adjustment element on the stand is aligned relative to a desired line of the vehicle, for example, the thrust line. A beam of light is transmitted between the two adjustment elements, and the technician adjusts the sensor until the beam position indicates a desired alignment of the sensor relative to the line of the vehicle.

Camera technique for adaptive cruise control (ACC) sensor adjustment

To determine a ride height dimension of a vehicle involves determining a set of spherical co-ordinates in three-dimensional space, for two points related to the vehicle, with respect to a datum point. The vehicle manufacturer designates a reference point and a point related to the vehicle body as the two points that correspond to the ride height specified for the measured ride height dimension. Determining the actual ride height dimension of the vehicle entails computing the dimension from the measured spherical co-ordinates of the two points, for example, as a distance between the points or as a difference in vertical height of the points. Examples of equipment include sensor modules for taking measurements of the co-ordinates of the points and processors for determining the desired ride height dimension from measurements taken by a sensor module.

Method and apparatus for determining ride height of a vehicle

An image processing type aligner enables proper set-up of one of two optical adjustment elements used to align an adaptive cruise control sensor or the like mounted on a vehicle. One element, such as a laser beam source, is mounted with the sensor on the vehicle; and the other element, such as a mirror, is mounted on a stand. A carrier on the stand positions two optical targets of the aligner at transversely spaced apart locations. The stand is positioned between the vehicle and the aligner and manipulated until the aligner indicates that the axis of the adjustment element on the stand is aligned relative to the thrust line of the vehicle. A beam of light is transmitted between the two adjustment elements, and the technician adjusts the sensor until the beam position indicates a desired alignment of the sensor relative to the thrust line.

Apparatus for use with a 3D image wheel aligner for facilitating adjustment of an adaptive cruise control sensor on a motor vehicle

A diagnostic method and system for determining an operational status of a multiple-link steering system for steering an object attached thereto. The system includes a position determination system for obtaining positional signals related to a steering system, and a data processing system to calculate positional parameters of the steering system based on the positional signals. The data processing system includes a data processor for processing data and a data storage device for storing data. The data storage device bears instructions upon execution by the data processor causing the data processing system to receive a first, second and third positional signal of the steering system when the object being steered to a first, second and third steering angle respectively. The data processing system calculates a first positional parameter for the steering system based on the first and second positional signals, and a second positional parameter for the steering system based on the second and third positional signals. An operational status of the steering system is determined based on the first and second positional parameters, and reference positional parameters.
