A mobile system and method of calibrating an ADAS sensor of a vehicle by aligning a target with the sensor, where a transport vehicle is equipped with a target adjustment stand for transporting to the vehicle, which is initially nominally positioned in front of the target adjustment stand that includes a movable target mount configured to support a target, with the target adjustment stand including one or more actuators for adjusting the position of the target mount. A computer system is used to determine an orientation of the vehicle relative to the target adjustment stand, with the position of the target mount being adjusted based on the determined orientation of the vehicle relative to the target adjustment stand. Upon properly orienting the target mount, and the target supported thereon, a calibration routine is performed whereby the sensor is calibrated using the target.

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.

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.

System for diagnosing the wheel alignment of a vehicle includes a measuring device configured to measure a characteristic parameter of the wheel alignment, wherein the measuring device comprises a wireless communication device to remotely transmit a signal related to the characteristic parameter. The system further comprises a portable remote device, distinct and separate from the measuring device, having a wireless communication device to remotely receive the signal related to the measured characteristic parameter, and a control unit adapted to receive the related signal from the wireless communication device and to carry out a step of processing the signal to derive a value of the characteristic parameter. The portable remote device further has a screen to display a characteristic information representative of the value of the characteristic parameter, and a battery connected to the wireless communication device, to the control unit and to the screen to allow their respective operation.

A system and method for aligning a floor target relative to a vehicle, the floor target including a calibration pattern for observation by a vehicle safety system sensor during calibration. The system includes at least one optical projection system consisting of at least one optical projector having an orientable projection axis. The optical projection system is operatively controlled by a processor to orient said projection axis towards a selected location on the floor surface relative to the vehicle, and to activate the optical projected to illuminate a point, a line, or a boundary, against which the floor target is aligned.

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 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 non-contact sensor for determining orientation of an object, such as a tire and wheel assembly of a vehicle, includes a projector assembly having a light emitter, a lens assembly and a mask, with the mask including mask apertures and the light emitter configured to project light through the lens assembly and mask apertures and onto the object, and with the mask apertures creating a light pattern of projected light onto the object. The sensor also includes an imager configured to image reflections of the light pattern from the object, and a processor. The projector assembly and imager are angled with respect to one another, and the processor is configured to process imaged reflections of the light pattern to derive the orientation of the object, such as the alignment orientation of the tire and wheel assembly.

A vehicle service system including a set of cameras and a processing system configured to access a database of vehicle-specific information, which includes data identifying vehicle-specific targets and/or service fixtures. The processing system is configured with a user interface to convey instructions to an operator, including the identification of vehicle-specific targets and/or service fixtures required to carry out a selected vehicle service. The processing system subsequently evaluates images acquired from the set of cameras to identify features present within the images, including placed vehicle-specific targets, from which identification of, and verification of correctly selected, vehicle-specific targets is made.

A vehicle wheel alignment system includes a pair of wheel mounted targets, a pair of reference targets mounted to a stationary reference, a pair of gravity sensors, and a pair of vehicle-mounted active heads mounted on first and second sides of the vehicle. The active heads each have an image sensor for producing image data of one of the reference targets and one of the wheel mounted targets. The gravity sensors are disposed on each side of the vehicle in a known relationship to either the respective reference targets or the image sensors. A data processor calculates, using the image data, a plurality of poses of the wheel mounted targets as the vehicle wheels rotate; calculates a vehicle drive direction using the target poses and a measured orientation relative to gravity from the gravity sensors; and calculates a wheel alignment measurement using the vehicle drive direction.
