A steer-by-wire steering system for a vehicle is disclosed, having a steering wheel, at least one sensor for capturing a steering angle of the steering wheel, a processing logic unit for determining a wheel setting angle requirement on the basis of the captured steering angle, and an actuator unit for setting a wheel setting angle at wheels of the vehicle according to the wheel setting angle requirement determined by the processing logic unit. The sensor is electrically connected directly to the vehicle electrical system and is supplied with electrical energy via the latter.
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.
The invention relates to a device for simulating seatbelt slack and/or for simulating seatbelt forces, with a guide (12) for a safety belt (20), which guide (12) comprises static guide elements (14) and a movable deflection element (16) which is adjustable relative to these from an initial state to an end state by way of an intermediate state, and with at least one inertial mass (18), wherein the guide path (17) predetermined for the safety belt (20) by the deflection element (16) and by the adjacent guide elements (14) is V-shaped in the initial state and the deflection element (16) and the inertial mass (18) do not interact, and is more weakly V-shaped in the intermediate state and the deflection element (16) and the inertial mass (18) interact, and the predetermined guide path (17) in the end state is at least approximately rectilinear.
