Abstract: The disclosure relates to a steer-by-wire steering system for a vehicle and with a steering device, the steering device having a manual steering handle, a steering sensor system and a feedback actuator, and with a wheel positioning device, the wheel positioning device having a positioning actuator for steering at least one wheel, and with at least one control device, the control device electrically connecting the steering device and the wheel positioning device to one another, and with at least one acceleration sensor, the feedback actuator and the acceleration data acquired by the acceleration sensor being used to provide haptic feedback at the steering handle.

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: An attitude control apparatus for a satellite includes: at least three electric motors, wherein the at least three electric motors are arranged in such a way that a torque may be generated with any orientation of an associated torque vector, and a controller, wherein the controller is configured to drive the at least three electric motors based on a torque controller. The torque controller is adapted to operate the at least three electric motors outside a rest state only when an acceleration torque and a braking torque are required to execute an agile attitude change maneuver. There is also described an associated method.

Abstract: The present disclosure relates to a method for determining a steering return moment requirement of a steering device of a vehicle, to a steering system, to a computer program product, and to a computer-readable storage medium.
