摘要： Vehicle alignment systems and methods are disclosed which operate based on a calculation of “drive direction,” or the direction in which a vehicle is moving. Since a vehicle can be assumed to be a rigid body, each wheel has the same drive direction. Consequently, an alignment parameter of one wheel can be compared to the same parameter of another wheel by equating their drive direction, eliminating the need for the aligner to “see” both sides of the vehicle at the same time. Embodiments include a system having one or more cameras on a fixture carrying a calibration element for an ADAS system, and one or more targets placed on the vehicle to measure the drive direction of the vehicle. The drive direction is assumed to be parallel to the vehicle thrust line and can be used as the line for orientation of the fixture to the vehicle.

摘要： The present invention relates to a device for determining the wheel geometry and/or the axle geometry of motor vehicles in an inspection room, using an optical measuring apparatus having at least one image-taking device which records a marking device including at least one body feature and one reference feature system, and having an evaluating device, the position of the reference features in the inspection room being known in the evaluating device, and the recording of the marking device taking place during travel of the motor vehicle. The image-taking device is connected to a wheel to be measured, at its wheel rim in pivot joint fashion, and follows the rotating motion of the wheel, the optical axis of the image-taking device always being aligned essentially perpendicular to the roadway plane and the axis of rotation of the pivot joint being aligned in all wheel positions essentially parallel to the roadway plane. The reference feature system is situated in the roadway plane in the field of view of the image-taking device, and the at least one body feature is always situated in the field of view of the image-taking device and follows the movement of the motor vehicle. The position of the axis of rotation and/or the plane of rotation of the wheel is able to be determined in the light of the position of a wheel feature that is to be ascertained.

摘要： A target system for determining the location of a position on a vehicle comprises a target body, one or more target elements, a trigger, and a point definer. The target elements are disposed on the target body and are detectable by a position determination system. The trigger is positioned on the target body and is remote from the position determination system. The trigger operates the position determination system by selectively changing the detection of one or more of the target elements by the position determination system. The point definer extends from the target body, and the point definer includes a point its a distal end. The point is capable of being located adjacent the position on the vehicle and is at a known location from the target body. The position determination system determines a location of the target body after detecting the target elements disposed on the target body. Methods of using the target system are disclosed.

摘要： A method and system for providing an improved camber adjustment technique. The method comprises the steps of: turning the steerable wheel to a first position in which the steerable wheel is either toe-in or toe-out, then turning the steerable wheel to a second position in which the steerable wheel is toe-out if the steerable wheel is toe-in in the first position, and in which the steerable wheel is toe-in if the steerable wheel is toe-out in the first position. Toe angles and camber angles during the turning of the steerable wheel from the first position to the second position are measured. An adjustment amount of camber at any toe angle is determined by the difference between the camber angle at zero toe and a specification camber angle.

摘要： An improved position determination system that is resistant to interference caused by glint, such as from the Sun. The position determination system for determining positional parameters of an object has a target device comprising a base configured for attaching to the object, first and second target surfaces connected to the base; wherein the planes on which the first target surface and the second target surface are located are non-parallel to each other. The position determination system further comprises an image sensing device configured for forming a viewing path intersecting the target device and generating image information indicative of the geometric characteristics of the target device, and a data processing device configured to couple to the image sensing device for determining the orientation of the object based on the image information. If one of the target surfaces becomes obscured as a result of glint, the image of the other target surface alone is sufficient to determine object orientation.

摘要： Apparatus and method for determining the alignment positions and orientations of vehicle wheels includes optical targets mounted on the wheels and optical targets mounted in a fixed relationship with respect to the surface on which the wheels are disposed. Video cameras are used to obtain images of the various optical targets and a computer is responsive to the images of the targets to determine values of wheel alignment parameters of the vehicle relative to said surface on which the vehicle wheels roll. The surface on which the wheels are disposed may be an automotive lift, and apparatus is disclosed for keeping the optical targets in the same position in the field of view of the camera(s) whether the lift is in its rest or in an elevated or reclined position.
