The DC motor is supplied by an on-board system DC voltage, in which the armature current and the motor voltage of the DC motor are detected and the actuating position of an actuating element is determined from a time profile of the armature current by counting the current ripple contained therein. During an initial phase, the armature current which rises over time is replicated by a function which is determined from pairs of values for the motor voltage and the armature current which are detected in a time interval. A current value of the armature current expected at a later point in time is extrapolated. In the event of a discrepancy between the armature current detected at this later point in time and the extrapolated armature current, a ripple count is started."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Processing a motor variable of a DC motor and actuating device for a motor vehicle","description":"A method processes a motor variable of a DC motor of an actuating device for a motor vehicle.
