摘要： A non-contact method and system for analyzing tire conditions. The system includes an emitter source for emitting radiation signals towards a tire having a treaded surface between two sidewalls. A detector is provided to receive signals reflected by the tire in response to the emitted radiation signals. A data processing system, coupled to the emitter source and the detector, obtains geometrical information, such as height, of a plurality points on the tire based on the signals received from the detector. The data processing system determines a condition of the tire by comparing geometrical information for a designated portion of the plurality points with other portion points on the tire. A color-coded surface profile showing a height distribution of the tire is also generated to assist diagnosis of the tire.

摘要： The present disclosure provides a method and system for determining symmetry and Ackermann geometry status of the steering system of a vehicle. A system according to the disclosure determines symmetry of the steering system based on toe angle differences of the steerable wheels. Thus, no specification is required for determining symmetry of the steering system. A system according to the disclosure determines symmetry of the steering system based on normalized toe angles. Consequently, the steerable wheel does not have to be positioned at a specific angle. Additionally, the present disclosure determines symmetry in the steering system of a vehicle without requiring turning steering wheels through a large angular range. Hence, technician efforts in steering the wheel are reduced. The disclosure also provides an improved alignment procedure that implements determination of symmetry of the steering system into the alignment procedure. The present disclosure provides a novel machine-implemented procedure to determine Ackermann geometry status of a steering system based on theoretical Ackermann angles.

摘要： In a vehicle alignment system an optical sensing mechanism is structurally coupled to a vehicle supporting lift for movement in unison with the lift so that the field of view of the sensing mechanism encompasses a wheel of a vehicle positioned on the lift during lift movement. Sensing modules may be selectively placed so that they are in correspondence with the vehicle wheel base. Modules may be deployed to extend outwardly from the lift, for viewing the wheel during an alignment procedure, or retract to a adjacent the lift for stowing. A protective cover extends above the sensing modules in the retracted position.

摘要： A four sensor wheel aligner has a single omnidirectional angle sensor mounted on each of four vehicle support wheels. Each sensor is in optical communication with the other sensors. Data is produced from which toe, camber, caster and steering axis inclination angles are computed. No reference is made to vertical. Redundant data sets are produced which provide system reliability and error tracking features and maximum accuracy from available data sets. Frame distortion measurements are made to facilitate collision repair in coordination with wheel alignment.

摘要： An apparatus and method for monitoring and automatically calibrating the primary sensors of a vehicle wheel aligner comprises secondary sensors for signaling the control means of the wheel aligner when the wheels are in known angular orientations. The outputs from the primary angle determining sensors of the wheel aligner are recorded when the secondary sensors signal the control means, and the control means calculates a calibration relationship between the outputs and the known angles to apply to future outputs of the primary sensors.
