A steering device which is configured as a steer-by-wire steering device includes a steering shaft disposed for rotation in a circumferential direction, a casing tube at least partially encompassing the steering shaft where the steering shaft is fixed in relation to the casing tube in an axial direction of the steering shaft, a sleeve encompassing the steering shaft, and a locking device. The steering shaft has an external thread which meshes with an internal thread of the sleeve. The sleeve is form-fitted into the casing tube such that the sleeve is displaceable in relation to the casing tube in the axial direction and is fixed in the circumferential direction. A lateral surface of the sleeve has a recess. The locking device and the recess are disposed such that the locking device is engageable into the recess in an axial position of the sleeve.

Steering device, motor vehicle having such a steering device, and method for operating such a steering device

A spindle drive for the height adjustment of an electrically adjustable steering column and the steering includes an adjustment spindle rotatably mounted in two bearings. The adjustment spindle includes two clamping elements, which have a centering cone on their sides facing one another, and the adjustment spindle is arranged in a tensioned manner on the two bearings by means of the clamping element, in that the clamping elements abut on the outer sides of the centering cones facing away from one other. The outer sides of the bearings are formed having a counter contour to the respectively abutting centering cone.

A steering column arrangement for motor vehicles with a vehicle-side console, on which an outer tube of a steering column carrying a steering shaft is attached in a releasable manner by means of a clamping device. The clamping device comprises at least one clamping wedge arrangement by which an increased holding force of the clamping device can be achieved during an axial displacement of the outer tube caused by an accident.

A method and a device are for detecting the initiation of the driving off process by a driver of a vehicle. The time derivatives of the engine torque and of the engine speed are determined, and the initiation of the driving off process is then inferred from an evaluation of these time derivative values. The detection of the driving off process can be used for releasing a brake while avoiding unintentional rolling of the vehicle when making a hill start.
