Abstract

A method and a device for controlling a controller having a capacitive element. An ohmic resistor is connected in parallel to the capacitive element. The value of the ohmic resistor is determined at certain times, and then the type and/or temperature of the capacitive element is deduced on the basis of the value of the resistor.
