  • Method for improving the steering feel in the case of a recirculating ball steering system
    Patent number: 10308281
    Abstract: The invention relates to a method for compensating a stick-slip effect in the case of a recirculating ball steering system (20) having a steering housing (22), in which a steering piston (24) is supported between a first working chamber (34) and a second working chamber (36), wherein the steering piston (24) has a toothed region (26) on the steering-piston outer wall of the steering position, with which toothed region teeth (28) of a segment shaft (30) mesh, the steering piston (24) can be moved along a longitudinal axis X-X, the working chambers (34, 36) are connected to a control valve (39) by means of pressure-medium lines in order to provide steering assistance, the control valve (39) is connected to a processor unit (40), by means of which valves of the control valve (39) can be actuated, and the processor unit (40) is connected to a sensor (42), which determines rotation of the steering column both in a first direction of rotation and in a second, opposite direction of rotation.

  • Method for compensating the play in the gearing between a steering wheel and a steering valve
    Patent number: 9744991
    Abstract: An operating method for a hydraulic servo steering system of a motor vehicle includes a steering cylinder that applies the supporting force to a steering gearing is integrated into a hydraulic circuit by means of a steering valve. The steering valve opening specifies the supporting force, wherein the supporting force is set by the steering valve in accordance with a steering torque applied to a steering wheel, by means of a gearing having play. The steering system further includes an actuator that acts on the gearing in order to cause relative adjustment of the gearing. The opening method provides for a compensation step in which, provided that a steering direction reversal is detected, the gearing is relatively adjusted by means of the actuator in a direction opposite the prior engagement direction of the gearing for a predefined duration or a predefined adjustment distance.
