1. A process for triggering an actuator in cycles, the process comprising the steps of:
- detecting an engine speed value;
determining whether the engine speed value is within a predetermined value range; and
when the engine speed value is within the predetermined value range, varying a triggering signal frequency over time according to a predetermined function, the predetermined function being independent of the engine speed value, wherein the triggering signal frequency is varied to prevent resonance effects.

Abstract
A process and device for triggering an actuator are described, in particular an actuator triggered in cycles for an internal combustion engine. The triggering signal frequency can be changed to prevent resonance effects. The triggering signal frequency is varied between a first and a second limit value over time according to a preselected function.
