Abstract

A method for triggering an electromechanical coupling unit having at least two coupling windings, and a steering system for implementing the method, are provided. The coupling unit selectively closes, and in this manner provides a mechanical coupling, only if both coupling windings are no longer supplied with electrical energy.
