    摘要: 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.
