Abstract

A vehicle engine control apparatus has a driver-operated engine operation preset control element and a speed regulation stage and/or limiting stage for regulating or limiting, respectively, the speed of travel using an engine-power-related nominal preset signal and emitting an engine-power-related speed regulation or speed limiting control signal. A torque characteristic stage emits an engine-torque related nominal preset signal as a function of the operation of the engine operation preset control element and of engine rotation speed information. This nominal preset signal is supplied to an engine/power characteristic stage which is provided on the input side of the speed regulation or limiting stage and determines the engine-power-related nominal preset signal from this as a function of the engine rotation speed. The engine-power-related speed regulation or speed limiting control signal is transformed to an engine-torque-related control signal by means of a power/torque characteristic stage on the output side.
