Abstract: A soft target movement platform (1) which comprises at least one drive unit (11), each unit having a motor carrier (12). The drive motor (21) is preferably journaled in the motor carrier about an axis central and longitudinal of the motor. A drive wheel (6) is drivingly connected to the drive motor, with the wheel's axis of rotation offset from the central longitudinal axis by a lever arm (31). The lever arm having a horizontal extent in use, whereby wheel load tends to rotate the motor with respect to the carrier about the longitudinal axis. A spring (32) acting between the drive motor and the carrier counteracts the wheel load rotation.

Abstract: 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.

Abstract: A ball screw mechanism includes a ball nut member that threadedly engages with a rack shaft via a plurality of balls, and a rolling bearing including an outer ring retained by a housing, an inner ring retained by the ball nut member, and a plurality of rolling elements. The ball screw mechanism moves the rack shaft in an axial direction relative to the housing through rotation of the ball nut member. A method for inspecting the ball screw mechanism includes fixing the outer ring to a fixing jig, pressing the rack shaft in the axial direction while restricting its rotation to rotate the ball nut member together with the inner ring relative to the outer ring, measuring an amount of a run-out of the rack shaft along with the rotation of the ball nut member, and determining whether the amount of the run-out satisfies a predetermined condition.

Abstract: A device for checking the wheel suspension of a vehicle, in particular, of a motor vehicle, includes: a device for determining the wheel normals and/or the center of rotation of a wheel of the vehicle; a device for determining the movement trajectory of the wheel normals and/or of the center of rotation of the wheel during a movement of the vehicle; and a comparison and evaluation device, which is configured to compare the determined movement trajectory of the wheel normals and/or of the center of rotation of the wheel to a predefined movement trajectory, and to output a defect message when the deviation of the determined movement trajectory from the predefined movement trajectory exceeds a predefined limiting value.

Abstract: A method of tuning a calibration table for an electric power steering system includes connecting the electric power steering system to an actuator machine, and communicating a control input from a vehicle simulator to the actuator machine. Input forces and steering angles are applied to the electric power steering system with the actuator machine, based on the control input. The electric power steering system is controlled with a steering controller, to apply a steering setting, i.e., and assistive torque. The steering controller uses the calibration table to define the steering setting, based on the applied input forces and steering angles. A steering torque in the electric power steering system generated in response to the applied steering setting is sensed, and communicated to the vehicle controller, thereby establishing a closed loop, feedback system. The calibration table may then be re-defined based on the sensed steering response for the applied input forces.

Abstract: A multi-turn angular position sensor includes a fixed magnet non-rotationally coupled to a fixed structure. A shaft is configured to rotate multiple complete rotations from a reference position, where each complete rotation front the reference position in a rotational direction defines a unique rotation zone of the shaft. Rotatable magnets surround the shaft and are disposed between the shaft magnet and the fixed magnet and are configured to rotate a different number of angular degrees than the shaft magnet. One of the rotatable magnets is a zone sensor magnet that rotates no more than one complete rotation from the reference position. A rotational zone sensor supplies a zone sensor output signal that indicates the unique rotation zone of the shaft. A shaft rotation sensor supplies a shaft rotation output signal representative of a number of angular degrees that the shaft rotates within each unique rotation zone.

Abstract: A time series myoelectric potential signal is acquired, which is representative of time series activity amount of a muscle of a driver when the driver is performing a driving operation on the vehicle, the muscle being involved in the driving operation. Based on the acquired time series myoelectric potential signal, a parameter value indicative of a fluctuation amount of the time-series myoelectric potential signal and an average value of the myoelectric potential signal are obtained. Drivability of the vehicle is evaluated based on the obtained parameter value and the obtained average value.
