Method of diagnosing a valve, diagnosis module, and valve

Abstract

A method of diagnosing a valve is described, which has an electrodynamic actuator, which includes a magnet arrangement for generating a magnetic field and a control element which is movable relative to the magnet arrangement and is coupled to a movably arranged coil. At least one electrical variable of the electrodynamic actuator is measured over a measurement period to detect a time course of the electrical variable. The time course of the electrical variable is evaluated over an evaluation period to determine at least one induction-dependent valve variable which is assigned to the motion profile of the electrodynamic actuator. A diagnosis module and a valve are furthermore described.

Dependencies are inferred from the claim text.
