1. A method for ascertaining a movement of an armature of an electric intake valve, the method comprising the following steps:
controlling an electrical variable of the electric intake valve to predefined values using a two-position controller;
determining a longest deactivation phase of the intake valve based on a deactivation phase duration calculation that depends on at least one deactivation time for the two-position controller and at least one activation time for the two-position controller; and
ascertaining a characteristic point in time of the movement of the armature based on switching behavior of the two-position controller, wherein a start of only the longest deactivation phase is used as the characteristic point in time.
