Abstract
A method for controlling an internal combustion engine provides that the internal combustion engine is operated based on a first injection pattern in a first operating state, and based on a second injection pattern in a second operating state. At least one parameter of the injection patterns in the transition from the first to the second operating state is selected in such a way that the noise emission remains constant. In the transition to the injection pattern having greater noise, first the at least one parameter of the first injection pattern is varied, whereupon the switchover takes place. In the transition to the injection pattern having the lower noise, first the switchover is implemented, whereupon the at least one parameter of the second injection pattern is varied.
