Abstract

A method for controlling at least one switchable valve, a brake impulse that slows down the valve movement being produced during the controlling of the at least one valve. At least one parameter of the brake impulse determines the position and/or the duration of the brake impulse. A parameter is modified, and the reaction of a measurement quantity or of a characteristic feature derived from the measurement quantity is evaluated.
