A method for aligning a calibration device with a vehicle based on a wheel aligner and a calibration system are provided. The wheel aligner includes an image sensor and a computer. The computer controls at least one image sensor to image a vehicle-mounted target on a vehicle, and processes the obtained image to determine a position of the vehicle. The computer controls the at least one image sensor to image a reference target on a calibration device, and processes the obtained image to determine a position of the calibration device. The computer determines an adjusting mode of the calibration device according to the position of the vehicle and the position of the calibration device, so that the calibration device is aligned with the vehicle according to an anticipated position or direction. The method can guide an operator to accurately align the calibration device with the vehicle.

The vehicle inspection device is used to adjust an optical axis of a radar device R in a vehicle in which the radar device R that acquires external environment information is attached to a vehicle body. The vehicle inspection device includes: a target robot T including a corner reflector 75 that reflects an electromagnetic wave emitted from the radar device R, and an electromagnetic wave characteristic measurement device 76 that measures characteristics of the electromagnetic wave emitted from the radar device R; and a control device 6 that controls the target robot T. The control device 6 calculates an attachment position of the radar device R and a direction of an optical axis on the basis of electromagnetic wave characteristics measured by the electromagnetic wave characteristic measurement device 76, and moves the target robot T to an inspection position that is determined on the basis of the calculation result.

A heavy-duty vehicle measurement system utilizing displacement sensor modules disposed in housings on opposite sides of a vehicle inspection lane to acquire a set of displacement measurements associated with a moving heavy-duty vehicle. Displacement data along one or more measurement axes is acquired independently by each of the displacement sensor module to measure corresponding distances between the sensor module and points on a surface of the passing heavy-duty. A processing system is configured to receive and evaluate the set of displacement measurements, together with known parameters of the measurement system, to identify heavy-duty vehicle features, such as configuration, body panels, wheel assemblies, and tire surfaces, and to calculate heavy-duty vehicle parameters such as velocity, wheel rim or tire dimensions, axle relative orientations (scrub angles) and wheel assembly spatial orientations.

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 device for wheel alignment measurement comprises at least two sensors which are configured to record each time at least two images of the front wheels and the rear wheels of a vehicle passing by; and an evaluation device which is configured to evaluate the images recorded by the sensors in order to determine whether the vehicle has traveled along a straight line. The sensors are arranged such that a vehicle to be measured can pass between the at least two sensors. The evaluation device is configured to determine the geometric travel axis of the vehicle and/or the individual tracks of the wheels on the front axle and/or the rear axle of the vehicle when the evaluation of the images recorded by the sensors reveals that the vehicle has traveled along a straight line.

A vehicle measurement station utilizing one or more displacement sensors disposed on each opposite side of an inspection region of a vehicle inspection lane to acquire displacement measurement data along associated measurement axes. At least a portion of the displacement measurement data is associated with the outermost wheel assemblies on an axle of a moving vehicle passing through the inspection region, and utilized to determine one or more vehicle characteristics, such as an axle total toe condition.

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.

A wheel alignment system includes a side-to-side reference including an active reference pod and a passive reference pod disposed on opposite sides of the vehicle. The active reference pod includes a reference image sensor fixedly attached to a reference target, for mounting on a first side of the vehicle such that the reference image sensor produces image data including a perspective representation of the passive reference pod disposed on a second/opposite side of the vehicle. In operation, alignment cameras on the opposite sides of the vehicle capture perspective representations of targets mounted to vehicle wheels and of targets of the active and passive reference pods. A computer processes the image data to compute an alignment measurement of the vehicle based on a spatial relationship between the active reference pod and the passive reference pod determined according to the image data produced by the reference image sensor.
