Abstract: A device for electronically controlling adjusting devices in an internal combustion engine in which the adjusting devices can be controlled, by comparing differentiated engine speed signals with predetermined threshold values in such a way that shuddering oscillations of the internal combustion engine are counteracted. The engine speed variable (n) is derived by means of a sensor (10) which provides a plurality of pulses per revolution of the engine crankshaft or camshaft. A first divider (14) divides the pulses from the sensor (10) by a fixed ratio. The output of the divider (14) is further divided in a divider arrangement which provides different divider ratios in dependence upon engine speed, the divider ratios being chosen so that measurement at engine speed is made over a complete combustion period of the engine, or a multiple thereof.

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.
