Abstract

In a method of a start-stop control for an internal combustion engine including briefly stopping and starting the internal combustion engine using an electric machine as a starter, the internal combustion engine is switched off by an engine control when switch-off conditions obtain, and the start-stop control queries whether a start signal exists on the basis of switch-on conditions. In order to ensure that a restart of the internal combustion engine is able to be performed more quickly, the start-stop control acts on the internal combustion engine using an operating strategy within a time period t until the internal combustion engine comes to a standstill.
