Abstract
An assembly consisting of a control member which comprises a carrier, an operating part movably supported on the carrier, an electromagnetic actuator comprising an armature and a coil for driving the operating part movingly relative to the carrier is provided. The assembly further comprises an electronic control system connected in an electrically conductive manner with the electromagnetic actuator for applying a control voltage to the electromagnetic actuator for a predetermined control period in a control step in order to generate a haptic feedback; a measuring circuit connected in an electrically conductive manner to the electromagnetic actuator for measuring a current present at the electromagnetic actor and for generating a measuring signal proportional thereto; and an evaluation unit connected in an electrically conductive manner at least to the measuring circuit and designed, in a measuring step offset in time relative to the control step, to apply a measuring voltage to the electromagnetic actuator by the electronic control system for a predetermined test period shorter than the control period, in order to measure by the measuring circuit the current which arises at the ele…
