Abstract

A method is provided for operating a hybrid vehicle (1) having an internal combustion engine (2), an electric machine (4) and having a regenerable filter device that absorbs fuel vapors from a fuel tank of the internal combustion engine. To improve the reproducible operation of a hybrid vehicle with an internal combustion engine and an electric machine, in a purely electric driving mode in which the hybrid vehicle (1) is driven only by the electric machine (4), the regenerable filter device is rinsed by switching on the internal combustion engine (2) with a scavenging strategy that is dependent on the velocity of the hybrid vehicle (1).
