Abstract
A method for stopping an internal combustion engine, in which an air flow supplied via an air metering device, in particular a throttle valve of the internal combustion engine, is reduced after a stopping request has been ascertained, an undershoot point in time is ascertained, at which an ascertained speed of the internal combustion engine falls below a pre-definable speed threshold value, after the undershoot point in time, the air flow supplied via the air metering device of the internal combustion engine is increased again, the predefinable speed threshold value being selected in such a way that an intake cylinder no longer enters a compression stroke after the increase of the supplied air flow until the internal combustion engine is at a standstill, a degree of opening of the air metering device to increase the supplied air flow being selected as a function of a coasting speed of the internal combustion engine.
