摘要： A system and process for aligning wheels of a three-wheel cycle include mounting targets to two wheels on an axle of the three-wheel cycle and positioning an alignment device relative to a single wheel of the three-wheel cycle to create a virtual axle and assess thrust angle. Once targets are in place, thrust angle is reduced to zero, and camber, caster, and toe measurements are taken and adjusted as needed to achieve three-wheel alignment.

摘要： An improved method and system are provided for performing rolling runout compensation for vehicle wheel alignment. A plurality of sets of camber and toe measurements are acquired for a pair of vehicle wheels, each at a different, relatively small rollback angle between measurements; e.g., rolling the vehicle more than 0° and less than 180° from the last wheel position. Best fit sine waves are computed for each of the camber and toe measurements using the acquired data, and the best fit parameters are applied to compute runout at the current wheel angle. The computed runouts are subtracted from the measured camber and toe values to get true camber and toe values of the pair of wheels.

摘要： A hybrid wheel alignment system and methodology use passive targets for a first pair of wheels (e.g. front wheels) and active sensing heads for another pair of wheels (e.g. rear wheels). The active sensing heads combine image sensors for capturing images of the targets with at least one spatial relationship sensor for sensing a relationship between the active sensing heads. One or both of the active sensing heads may include inclinometers or the like, for sensing one or more tilt angles of the respective sensing head. Data from the active sensing heads may be sent to a host computer for processing to derive one or more vehicle measurements, for example, for measurement of parameters useful in wheel alignment applications.

摘要： The invention relates to a method for optically measuring a chassis at a testing station. According to said method, radiation that is reflected by several optically distinguishable characteristic structures on a vehicle, comprising at least one wheel and a surrounding bodywork section, is detected by a measuring device with the aid of an image capture unit and at least the wheel plane and the wheel centre point are determined by an evaluation of the positional data obtained by means of the detected radiation. To obtain reliable measurement results relatively simply, several planes are projected at least onto the wheel (5) and the surrounding bodywork using structured light that is emitted by at least one radiation source of the measuring device, and the intersection of the planes with the wheel (5) and the surrounding bodywork or with a sub-section of the wheel and bodywork is captured as profile lines (3D point cloud) by means of at least one image capture unit, on the basis of a known geometrical assignment of the radiation source or sources to the image capture unit or units. From the intersection points of the profile lines with e.g. the edge of the rim or other rotationally symmetrical contours on the wheel and the wheel opening, the spatial position of characteristic surface points is determined, said points being used to directly determine the relevant chassis data.

摘要： An apparatus and method is provided for measuring the caster angle of a steerable wheel assembly without contact with the vehicle. An image capture device, preferably a CCD type video camera or sensor, views a vehicle wheel mounting and steering assembly that is illuminated by a light source. Information from the captured image is transmitted to a computer based control, such as a computer or processor, that determines the angle of a preformed line or preselected physical features on the wheel assembly in the captured image, and determines the caster angle of the steering axis based on the fixed angular relationship of the line or physical features to the steering axis that is stored or accessed by the control. Preferably, the image capture device is mounted below the vehicle on a vehicle alignment machine that supports the vehicle.
