Abstract: A steer-by-wire steering system for a vehicle is described, with a driver-operable control element for steering angle input, an actuating mechanism for setting a wheel setting angle, and with a control unit which is configured, on the basis of a steering angle of the control element and a vehicle speed, to output a map for the setpoint of a position of the actuating mechanism. A defined maximum steering angle is assigned to a maximum wheel setting angle. A method is also described for producing a map for the setpoint of a position of the actuating mechanism in a steer-by-wire steering system.

Abstract: In a method for producing a haptic feedback force by setting a manual torque at a steering intention input device of a steering system of a motor vehicle, a first and a second rack force value are obtained from two different models. The rack force values originating from the two models are processed to form a quotient, which determines a feedback force value, by the second rack force value being modified by the quotient, and the feedback force value is transferred to a steering reference torque generator of the steering system, which sets the manual torque at the steering intention input device in dependence on the feedback force value.

Abstract: A steering column assembly for a motor vehicle has a bearing housing and a steering shaft which is mounted in the bearing housing, and an adjusting apparatus, by which the steering shaft can be adjusted. The adjusting apparatus has a drive with a drive element, a motor with a drive shaft, and a first flexible guide element which runs in a tensioned manner in a first tensioning direction between two first tensioning points. Here, furthermore, the drive element is wrapped around at least once without play by the first guide element and is coupled to it in a torque-transmitting manner such that the drive moves along the first guide element in or counter to the first tensioning direction when the drive shaft rotates in or counter to a rotational direction. Furthermore, a motor vehicle with a steering column assembly of this type is provided.

Abstract: A method for operating an electromechanically assisted steering system of a motor vehicle is described. The steering system has a steering arrangement and at least one electromechanical actuator.
