Abstract

A method and device for driving an electromagnetic valve, in particular an electromagnetic valve of a braking system having antilock protection and/or a traction control system. When switched over into the position that permits the passage of flow, the valve is so driven that, in a first phase for a specifiable time (DT), the current falls off in accordance with a first function and remains nearly constant over time in a second phase.
