Method And Apparatus For Calibration Of No-Compensation And Universal Wheel Adapters Utilized In Vehicle Wheel Alignment Procedures

View page
US Patent:
6427346, Aug 6, 2002
Filed:
Jun 1, 2000
Appl. No.:
09/585006
Inventors:
Michael T. Stieff - Wentzville MO
Timothy A. Strege - Ballwin MO
James W. McClenahan - Hazelwood MO
Assignee:
Hunter Engineering Company - Bridgeton MO
International Classification:
G01C 2500
US Classification:
33203, 3320318
Abstract:
A method and apparatus for the calibration of vehicle wheel alignment sensors or optical targets and for the detection and correction of wear or damage to no-compensation type wheel adapters to which the vehicle wheel alignment sensors are attached during a vehicle wheel alignment procedure. A first aspect of the present invention is a method for electronically storing separate calibration values associated with a vehicle wheel alignment sensor or optical target for a variety of types of vehicle wheel adapters. A second aspect of the present invention is a method and apparatus for detecting and compensating for wear or damage to no-compensation type wheel adapters by utilizing a known flat surface against which the contact points of the adapter are placed, any misalignment of the sensor mounting shaft axis from the plane is detected and corrected for, either by adjustment of the contact points or by adjustment of the sensor mounting shaft. An additional aspect of the present invention is the inclusion of more than three contact points on the wheel adapter to which the vehicle wheel alignment sensor is attached to facilitate detection of damage or wear to the wheel adapter by providing a visual indication of the damage or wear when the wheel adapter is placed on the flat surface.

US Patent:
6483577, Nov 19, 2002
Filed:
Mar 16, 2001
Appl. No.:
09/810357
Inventors:
Michael T. Stieff - Wentzville MO
Assignee:
Hunter Engineering Company - Bridgeton MO
International Classification:
G01B 1126
US Classification:
35613909, 3320312
Abstract:
A vehicle alignment sensor system includes a first sensor assembly for measuring at least a first angle with respect to a fixed reference, that angle being related in a predetermined manner to an alignment angle of a vehicle whose alignment is to be measured, and a second sensor assembly for mounting in a known geometrical relationship to a wheel of a vehicle whose alignment is to be measured. The first sensor assembly has at least one detector, and the second sensor assembly has at least a pair of emitters in fixed geometrical relationship with respect to each other. The detector is capable of measuring the apparent geometrical relationship of the pair of emitters to determine a relative alignment angle of the vehicle, so that a true alignment angle of the vehicle is determinable from the first angle and the relative alignment angle. A calibration method using the present invention is also disclosed.

US Patent:
7043396, May 9, 2006
Filed:
Dec 19, 2003
Appl. No.:
10/741501
Inventors:
Timothy A. Larson - Ferguson MO, US
Dennis D. Bowen - St. Peters MO, US
Michael T. Stieff - Wentzville MO, US
Assignee:
Hunter Engineering Company - Bridgeton MO
International Classification:
G01C 9/00
G01B 11/275
G01B 5/24
US Classification:
702151, 3320314, 3320318, 73122, 73146, 340 28, 340442, 340933, 701 36, 703 8, 702 94, 702 95, 702150
Abstract:
A method and apparatus for guiding an operator in the alignment of the wheels of an automotive vehicle which has been either modified from a original manufacturer configuration, or for which no previously established alignment settings are known. Initially, the operator identifies known information about the vehicle and selects a desired characteristic of the vehicle for which the vehicle alignment is to be optimized. A set of initial alignment settings are presented to the operator, based upon the selected characteristic for the vehicle, and the vehicle alignment is adjusted thereto. One or more subsequent measurements of the vehicle are acquired. Alignment adjustments to further improve the selected characteristic, identified in response to the vehicle measurements are presented to the operator. The process of alignment adjustment, measurement, and presented adjustments is repeated until an optimal alignment setting for the selected characteristic is reached.

Microelectronic Vehicle Service System Sensor

US Patent:
7100289, Sep 5, 2006
Filed:
Dec 22, 2004
Appl. No.:
11/024215
Inventors:
Timothy A. Strege - Sunset Hills MO, US
Michael T. Stieff - Wentzville MO, US
Assignee:
Hunter Engineering Company - Bridgeton MO
International Classification:
G01B 7/30
US Classification:
33203, 3320312
Abstract:
Compact and robust sensors for utilization with vehicle wheel alignment angle sensor units and vehicle service devices. The sensors incorporate one or more micro-electromechanical devices configured to measure movement and/or orientation of the sensor about one or more orthogonal axes, such as when a wheel alignment angle sensor unit is coupled to a vehicle wheel during a vehicle wheel alignment angle measurement procedure, or when a vehicle lift system is articulated to raise or lower a vehicle. The sensor are further configured to provide output signals representative of the measured movement and/or orientation to a vehicle wheel alignment system processor or vehicle service device controller.

International Classification:
G01B 11/275
G01B 5/255
US Classification:
3320318, 33288
Abstract:
A machine vision vehicle wheel alignment system optical target assembly incorporating an adaptor for attachment of an optical target to a vehicle wheel assembly. The adaptor includes at least three contact points for abutment against surfaces of a vehicle wheel assembly, and an attachment mechanism configured to grip surfaces of a tire mounted to the wheel rim to hold the optical target assembly in contact with the wheel assembly surface. The optical target is secured to the adaptor, and maintained in a fixed relationship to the wheel assembly thereby during a vehicle wheel alignment measurement procedure.

Appl. No.:
12/120460
Inventors:
Michael T. Stieff - Wentzville MO, US
Gregory F. Meyer - St. Louis MO, US
Dennis M. Linson - St. Charles MO, US
Assignee:
Hunter Engineering Company - Bridgeton MO
International Classification:
G01B 11/275
G01B 5/255
US Classification:
3320318, 33288
Abstract:
A machine vision vehicle wheel alignment system optical target assembly which incorporates an adaptor for attachment of an optical target to a vehicle wheel assembly. The adaptor includes a circular sinusoidal edge for seating in a non-determined position against surfaces of a vehicle wheel assembly, and a pair of pivoting arm assemblies capable of independent movement which are configured to position tire hooks for gripping the tread surfaces of a tire mounted to the wheel rim. Forces exerted between the pivoting arms are transferred to the tire hooks to hold the optical target assembly in contact with the wheel assembly surface. The optical target is integrated into the adaptor, and maintained in a stationary relationship to the wheel assembly thereby during a vehicle wheel alignment procedure.
