Abstract
A device for detecting the movement of a movable component in that the position signals furnished by two position sensors are added to a signal that is conducted through a signal line to an evaluation arrangement. The position ranges associated with the position sensors have an overlapping region. From the position signals, a signal processing arrangement determines a direction signal and a speed signal. Two current sources are actuated by the direction signal and the speed signal to impress predetermined currents in the signal line. The currents are added in the signal line. In a first embodiment, a signal transmitted over the signal line has four different levels. In another embodiment, the signal transmitted over the signal line has three different levels. The device according to the present invention is particularly suitable for use in an adjustment drive provided in a motor vehicle.
