A system and method for aligning a target to a vehicle for calibration of a sensor equipped on the vehicle includes multiple non-contact wheel alignment sensors configured for use in determining the orientation of tire and wheel assemblies of the vehicle. A target adjustment frame includes a target mount moveably mounted on a base frame, and includes multiple actuators configured to selectively move the target mount relative to the base frame, where the base frame is in a known orientation to the non-contact wheel alignment sensors. A computer system selectively actuates the actuators to position a target relative to the vehicle, with the target mount being moveable about a plurality of axes based on the determination of the orientation of the vehicle relative to the target adjustment frame to position the target relative to a sensor of the vehicle whereby the sensor is able to be calibrated using the target.

The present disclosure relates to the field of automobile engineering and provides a system for simultaneous measurement of “Wheel runout” and “Wheel alignment angles” of a multi-axle vehicle having a plurality of axles and wheels. The system includes a plurality of wheel targets, at least two camera modules, and an alignment control module. The plurality of wheel targets is respectively mounted on the axle wheels. Each of the camera modules has a camera that is configured to capture images of the plurality of wheel targets. The alignment control module has a processor co-operating with each of the camera module and configured to capture and analyze the images of the Targets to compute the “Runout”and “Wheel Alignment angles” of all the wheels of all the axles simultaneously. The processor is further configured to compare the analyzed wheel alignment angles with a predetermined range of acceptable wheel alignment angles.

A vehicle service system comprising a calibration apparatus, which is designed to calibrate an ADAS sensor of a vehicle, a calibration device and a position detection system, which comprises, in turn, two optical apparatuses, which are arranged on opposite sides of the vehicle and are configured to capture first images containing images of the vehicle. The optical apparatuses have respective positioning targets, which are oriented so as to face the calibration apparatus. The position detection system further comprises two cameras, which are mounted on the calibration apparatus so as to be arranged in lateral positions on opposite sides with respect to the calibration device. The two cameras are optically oriented towards the optical apparatuses so as to capture the images of the positioning targets.

A vehicle service system incorporating a pair of gimbal-mounted optical projection systems enables an operator to selectively orient each optical emitter of the optical projection system to illuminate a location on a vehicle surface in proximity to the system. Signals indicative of an orientation of each optical emitter about three-axes of rotation are received at a controller programmed with software instructions to utilize the received signals, together with known locations for the systems, to calculate a three-dimensional coordinate for the illuminated location within an established frame of reference. The controller is further programmed to utilize the calculated three-dimensional coordinate of the illuminated location as an origin point for determining one or more placement locations within the established frame of reference for ADAS sensor calibration or alignment targets.

A target installation apparatus for installing a target for aiming equipment mounted on a vehicle comprises: a reference point setting unit configured to set vehicle-side reference points on both exterior sides in a vehicle width direction of the vehicle, wherein the reference point setting unit includes: a rod-shaped member that extends in the vehicle width direction with respect to the vehicle and that is arrangeable to abut both tires of the vehicle; and a pair of reference point forming units that are attached to the rod-shaped member to be positioned on both the exterior sides of the vehicle in the case of being arranged with respect to the vehicle and that include marks formed to respectively indicate the reference points, and wherein the pair of reference point forming units respectively include moving portions that move the reference points in a front-and-rear direction of the vehicle.

An advanced driver assistance calibration device for vehicle comprises a target device, and a first laser wheel clamp and a second laser wheel clamp respectively disposed on two front wheels of the vehicle; a first scale and a second scale disposed on the target device, which are symmetrically distributed on both sides of a center of a crossbeam of the target device; wherein a third scale and a fourth scale are disposed on the first laser wheel clamp and the second laser wheel clamp respectively, and a first laser and a second laser are disposed on the first scale and the second scale respectively. The advanced driver assistance calibration device for vehicle provided by the disclosure uses two pairs of lasers respectively mounted on the wheel clamps and the target device, so the structure is simple, the installation and adjustment are convenient.

A method for calibrating an ADAS sensor of an advanced driver assistance system of a vehicle (9) comprises the following steps: (A) deriving an attitude parameter of the vehicle (9); receiving the derived attitude parameter in a control unit (11); (B) comparing the derived attitude parameter with a corresponding reference parameter; (C) aiding with the positioning of a support structure (3) near the service area (8), where a calibration device (41) is mounted on the support structure (3); sending a calibration command from the control unit (11) to an electronic control unit (95) of the vehicle (9) to determine an interaction between the ADAS sensor and the calibration device (41); processing data received from the electronic control unit (95) of the vehicle (9) in the control unit (11).

The present disclosure relates to a method determining wheel alignment parameter of a vehicle comprising a vehicle body. In particular, the method is performed by attaching a measuring arrangement to positions at a first and second longitudinally extending side portions of the vehicle body, respectively. A first and a second lateral center position are determined whereby a wheel alignment parameter in the form of a longitudinally extending centerline of the vehicle is determined.

A sensor calibration tool, in particular for calibrating sensors on a vehicle, includes a vertical rail defining a first axis, and first and second carriage assemblies. The first 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. The second carriage assembly is supported by the horizontal rail, movable along the second, and has a target mount that releasably supports a calibration target. A calibration tool includes a horizontal rail defining a first axis, a first carriage assembly movable along the first axis, a mounting bar defining a second axis and pivotable about a pivot axis transverse to the first and second axes, and a target mount positioned on the mounting bar. The first carriage assembly and the mounting bar move independently.

A system for checking the attitude angles of wheels is provided, in a manner that is known per se, with a vertical measuring or column 1 on which some transmitters and receivers of electromagnetic signals are installed—for example coherent light illuminators (typically lasers) and associated reflected light sensor—which overall define a group of distance sensors.

According to the disclosure, the proposed system is produced using distance sensors appropriately fitted on a single vertical measuring structure which is positioned, on a side of a movement path, where the vehicle equipped with wheels moves, that has a substantially transverse direction with respect to the acquisition direction of the distance sensors.
