摘要： A steer-by-wire steering system for a motor vehicle or a steering system for an autonomous driving motor vehicle includes a controller configured or programmed to control steering of steerable road wheels depending on a driver's input or an input of an autonomous driving unit and to include a normal mode of operation with full steering functionality and no quality problems, and at least two degraded modes with degraded operation of the steering system. The steering system includes an evaluator to evaluate a state of performance degradation of the steering system and to set the operation mode of the controller based on an evaluation result from the evaluator.

摘要： A steering gear for a steer-by-wire steering system of a motor vehicle may include a hollow shaft motor with a stator that is fixed to a housing and a rotatably supported rotor that is arranged coaxially with respect to a longitudinal axis. A worm gear may extend through the rotatably supported rotor. The worm gear comprises a spindle nut that is arranged coaxially relative to the longitudinal axis, that is connected in terms of driving to the rotor, and that is located on a spindle that is displaceable by way of the hollow shaft motor along the longitudinal axis. The angle of inclination of the worm gear may be less than 4.5°.

摘要： A steering gear for a steer-by-wire steering system of a motor vehicle may include an electric motor having a motor shaft. The motor shaft drives a spindle of a worm gear, and the worm gear comprises a spindle nut in such a manner that a rotational movement originating from the motor shaft is converted into a linear movement of the spindle nut along an axis. The spindle nut, for purposes of steering wheels of the motor vehicle, is connected to at least one tie rod. The worm gear may be a ball screw drive, a trapezoidal drive, or a roller screw drive.

摘要： A method to control a steering system or a sub-system of a road vehicle including a controller to operate in a normal mode with full steering functionality and no quality problems and at least two degraded operation modes with degraded operation of the steering system, the controller including an evaluator including an allocation between degradation levels of the steering system or the sub-system and operation modes, and the method includes determining an overall degradation level for the steering system or the sub-system by collecting single individual degradation levels of the steering system or the sub-system in the evaluator and determining an overall degradation level as a level with a highest degradation of the single individual degradation levels which in a corresponding operation mode provides enough performance of the steering system for an expected maximum power request.

摘要： A steering gear for a steer-by-wire steering system of a motor vehicle may include a coupling rod which is supported in a steering gear housing and on which a threaded spindle is formed, with the threaded spindle being surrounded by a spindle nut. The threaded spindle and the spindle nut may be part of a helical gearing, and the coupling rod is movable along a longitudinal axis by way of the helical gearing. The coupling rod is movably mounted in the steering gear housing along the longitudinal axis by way of a pressure piece having two bearing elements arranged on opposite sides of the coupling rod in a circumferential direction of the longitudinal axis.

摘要： A method for calibrating a position of a feedback actuator of a steer-by-wire steering system of a road vehicle includes moving the feedback actuator to a first end stop of the feedback actuator and from there moving the feedback actuator to a second end stop, recording a position of the two end stops and based thereon determining a newly defined center position, moving the feedback actuator to the newly defined center position, and storing the newly defined center position in a memory as an offset value of an absolute steering wheel angle.

摘要： A steer-by-wire steering system for a road vehicle includes a road wheel actuator to act on steerable wheels and electronically controlled as a function of a driver's steering request, a feedback actuator to transmit reactions of a road to a steering wheel, and a single steering wheel angle sensor to measure a steering wheel angle. The steering wheel angle sensor is an external sensor able to communicate on a second vehicle communication channel or via a private communication with the road wheel actuator. The steer-by-wire steering system also includes an external road wheel actuator position sensor to measure a position of the road wheel actuator and to communicate on the second vehicle communication channel or via the private communication with the road wheel actuator.

摘要： A steering column for a motor vehicle may include an inner casing in which a steering spindle is mounted rotatably about a longitudinal axis that extends in a longitudinal direction and is received in an outer casing in a slidingly adjustable manner in the longitudinal direction. A pretensioning apparatus may have a pressure piece that can be braced from an outside in a tensioning direction transversely to the longitudinal axis against the inner casing. The pressure piece is held in the longitudinal direction on the outer casing and is supported against a fixing element counter to the tensioning direction. The fixing element is fixed in a recess of the outer casing. The fixing element has a forming means that is plastically furrowed into the recess, and/or the recess has a forming means that is plastically furrowed into the fixing element.

摘要： A clamping apparatus may include a stroke-generating disk that is rotatable about a clamping axis and is connected via a first stroke-generating gearing and a second stroke-generating gearing to a pressure disk, which is stationary relative to the rotation of the stroke-generating disk. The first stroke-generating gearing converts a relative rotation of the stroke-generating disk in a first actuating angle range in the clamping direction into a first axial stroke relative to the pressure disk. The second stroke-generating gearing converts a further rotation of the stroke-generating disk following the first actuating angle range in a second actuating angle range into a second axial stroke between the stroke-generating disk and the pressure disk. At least one of the stroke-generating gearings is a tilting pin gearing, with at least one tilting pin supported in the direction of its pin axis between corresponding bearing points on the stroke-generating disk and the pressure disk.
