ABSTRACT OF THE DISCLOSURE An engine revolution control apparatus for a vehicle, in which revolutions of an engine when the engine is in the idling state, that is, when the vehicle is being stopped and a throttle valve is totally enclosed, is controlled by con- trolling opening of an air control valve which is provided in a by-pass conduit for by-passing the throttle valve ac- cording to the revolution feedback correction volume which was calculated according to the deviation between the-actual revolutions of the engine and its target revolutions which was set according to the load of the engine, increasing, in the non-idling state of the engine, the revolution feedback correction volume, which is calculated when the engine has shifted from the idling state to the non-idling state as well as when the deviation between the actual revolutions and the target revolutions is small, so that, when the engine is shifted to the idling state again, it is not li- able to be affected by such an undetected current consumer as an ON signal of a headlight which was injected when the engine was in the non-idling state and the actual revolu- tions can smoothly be converged on the target revolutions with better responsibility.
