Abstract

An actuating device for an operating element such as a clutch (4) in the power train between the engine (2) and the driven wheels (12) of a motor vehicle consists of a parallel arrangement of at least two actuators (25a, 25b) that are controlled by an electronic control device (31) so that they can work simultaneously or one after the other, or with a partial time overlap where one starts to work after an initial current surge to the other has subsided.
