ABSTRACT:
A driving device for a plurality of sensors or a plurality of actuators comprises a measuring unit for measuring currents flowing through the sensors or the actuators, and a switching arrangement for selectively energizing the sensors or the actuators. The driving device measures a current flowing through each of the sensors or the actuators by means of a single measuring unit, which is time shared.
