A sensor calibration system includes a calibration tool with a vertical rail defining a first axis, and two carriage assemblies. One carriage assembly is supported by the vertical rail, movable along the first axis, and has a horizontal rail defining a second axis transverse to the first axis. Another carriage assembly is coupled to the horizontal rail, and has a transverse mounting bar with a plurality of target mounts, each target mount configured to releasably support a respective calibration target.

The invention relates to a method for maintenance of a vehicle, comprising—determining (S2, S8) the position, in a fixed coordinate system, of at least one first part (2011, 4, 3011) of a vehicle, —characterized by determining (S3) the identity of the vehicle, —retrieving (S4, S10), by means of the vehicle identity, spatial data indicating how a second part (202, 2011, 4) of the vehicle is spatially related to the first part (201), and—determining (S8, S11) the position, in the fixed coordinate system, of the second part (202, 2011, 4) based at least partly on the first part position and the spatial data.

A wheel holder (2) for fastening to a wheel (1), in particular to a wheel (1) of a motor vehicle, comprises at least two arms (22, 23, 24) extending outward from a center (28) of the wheel holder (2) in a radial direction; each of the arms (22, 23, 24) having at least one movable element (32, 33, 34) that is movable in the radial direction; a rotation element (40) that is arranged in the center (28) of the wheel holder (2) such that it can rotate; at least two coupling elements (52, 53, 54) each extending between one of the movable elements (32, 33, 34) and the central rotation element (40) such that the movable elements (32, 33, 34) are movable in the radial direction by rotation of the rotation element (40); and at least one drive device (63, 64) which is connected to one of the movable elements (32, 33, 34) via a force transmitting element (73, 74) and which is designed to apply, via the force transmitting element (73,74), a force to the movable element (32, 33, 34) that is directed towards the center (28) of the wheel holder (2).

An apparatus (1) for calibrating an ADAS sensor of a vehicle (9) comprises: a base unit (2) including a plurality of wheels (20); a support structure (3) integral with the base unit (2); a vehicle calibration assistance structure (4), mounted on the support structure (3) and including a calibration device (41, 42) configured to facilitate aligning or calibrating the ADAS sensor; a position detector, configured to capture values of a position parameter representing a position of the support structure (3) relative to the vehicle (9); a processing unit, configured to process the values of the position parameter in real time to derive information regarding an actual position of the support structure (3) relative to the vehicle (9).

A support structure having a vertical element supporting a set of cameras associated with a vehicle measurement or inspection system together with at least one target structure required for realignment or recalibration of onboard vehicle safety system sensors. A camera crossbeam carried by the support structure locates the set of cameras as required to view a vehicle undergoing measurement or inspection. The target structure is affixed to the vertical element of the support structure, at an elevation suitable for observation by at least one vehicle onboard sensors during a realignment or recalibration procedure. A set of rollers facilitates positioning of the target structure on a supporting floor surface during a realignment or recalibration procedure.

A portable laser emitter, laser target, and method for measuring the toe angle of a commercial truck steer axle are disclosed. The laser emitter is mounted to the wheel of a truck steer axle while the laser target is placed in front of the truck. Measurements are taken of the laser dot position on the target with the emitter mounted at either end of the steer axle. The process is then repeated with the target positioned behind the truck. The measurements taken from either end of the steer axle with both front and rear target positions are compared to determine the toe angle of the steer axle.

The present invention relates to the fields of automobile maintenance and device calibration technologies and discloses an automobile calibration device. The automobile calibration device includes: a stand apparatus; a supporting assembly, mounted at the stand apparatus and movable in a vertical direction with respect to the stand apparatus; and a drive assembly, configured to drive the supporting assembly to move in the vertical direction with respect to the stand apparatus. In the foregoing manner, the supporting assembly can automatically ascend or descend and manual adjustment of the supporting assembly is avoided.

A calibrating method is provided including the following steps. A type of a first sensor and a type of a first sensor carrier are determined according to an external shape of a first object. The first sensor is carried by the first sensor carrier, and a relative coordinate of the first object is measured by the first sensor. The relative coordinate of the first object is compared with a predetermined coordinate of the first object to obtain a first object coordinate error, and the first object coordinate error is corrected. After the first object coordinate error is corrected, the first object is driven to perform an operation on a second object or the second object is driven to perform the operation on the first object. A calibrating system is also provided.

A target alignment system for calibrating a safety sensor mounted on a vehicle with front and rear wheels by locating an optimum target position upon a horizontal surface for accurate calibration of the sensor. The target alignment system comprises a plurality of visual guide projectors and a pair of target assemblies which project a visible guide line perimeter around the vehicle, the perimeter including parallel longitudinal lines on either side of the vehicle, a lateral alignment guide line crossing the longitudinal lines in front of the vehicle, and a center guide line colinear with the vehicle center line. The front and rear wheels of the vehicle are longitudinally aligned causing the vehicle thrust line to match the vehicle center line. One of the visual guide projectors projects a transverse line across the center guide line, creating an intersection point which marks the optimum target position.
