Abstract: A method for operating a motor vehicle, wherein the motor vehicle has a steering system for steering at least one wheel of the motor vehicle by means of a drive. In doing so, it is provided that a time span is determined for at least one countermeasure limiting a hazard to a vehicle occupant upon an at least partial failure of the steering system, within which time span the countermeasure deploys an effect, and that a state variable (T) influencing the operating capacity of the steering system is determined and extrapolated over time and a point in time (t1) is calculated in which the state variable (T) exceeds a limit value (T1), wherein the countermeasure is introduced when the point in time (t1) is less than the time span in the future.

Abstract: A redundant mechatronic system. The redundant mechatronic system is formed with two channels and is or can be connected for the output of a varying mechanical power to a mechanical arrangement, wherein each of the two channels includes an energy supply and an actuation circuit or a common energy supply is connected upstream of both channels, and both channels can be controlled by at least one control unit. The control unit acts on the actuation circuits in such a manner that the actuation circuits in each case switch an electric power specified by the control unit and drawn from the energy supply through to in each case a winding set of at least one electrically operated actuator, in order to generate the mechanical power. The two channels are operated in parallel during normal operation, in such a manner that each channel provides half of the mechanical power to be instantaneously output.
