Abstract

A device for the electronically controlled influencing of actuating devices of an internal combustion engine is proposed in which actuating devices can be influenced by comparing differentiated sensor signals with predeterminable threshold values. The actuating devices are directly accessed without a detour via any regulating devices. The system corresponding to the method thus becomes very simple and inexpensive in its construction. Control-loop-related oscillations are avoided by the direct influencing of the actuating device.
