Patent number: 9001189Abstract: A method and a device are provided for the optical axle alignment of wheels of a motor vehicle. At the wheels that are to be aligned, targets are mounted, having optically recordable marks, the targets being recordable by measuring units that have stereo camera devices. In a referencing process, using a referencing device that is integrated into the measuring units, a measuring position reference system is established for the measuring units. In a calibration process, in which a local 3D coordinate system is established using at least three marks of the target, the determination of a reference plane is carried out, using a significant mark of the target. Finally, using the reference plane, a vehicle longitudinal center plane is ascertained, while taking into account the measuring location reference system.Type: GrantFiled: August 26, 2009Date of Patent: April 7, 2015Assignee: Robert Bosch GmbHInventors: Guenter Nobis, Stefan Schommer, Adriano Macchia, Christian Wagmann, Jochen Backes, Volker Uffenkamp

Patent number: 8948444Abstract: A method for determining the tumbling motion of a vehicle wheel and/or a measurement object attached to the vehicle wheel in the context of an axle measurement. The tumbling motion is executed relative to the precise wheel axis of rotation of the vehicle wheel and at least one orientation value is determined between the precise wheel axis of rotation and a reference axis. Using at least one image recording unit, at least two wheel features that are present on the vehicle wheel or are attached for the measurement are acquired as the vehicle travels past and are evaluated by an evaluation device situated downstream. Using the wheel features recorded as the vehicle travels past, a wheel coordinate system and a feature coordinate system are determined. The wheel coordinate system and the feature coordinate system are set into relation to one another in order to determine the orientation value.Type: GrantFiled: March 2, 2011Date of Patent: February 3, 2015Assignee: Robert Bosch GmbHInventors: Guenter Nobis, Steffen Abraham, Volker Uffenkamp
