A process for operating a hybrid vehicle in an internal-combustion-engine-driven mode and/or in an electric-motor-driven mode, wherein, on a route section to be traveled and considered for driving in the electric-motor-driven mode, a change to the electric-motor-driven mode will take place only when a threshold value is exceeded which represents, or correlates with the efficiency advantage achievable on the route section by a change from the internal-combustion-engine-driven mode to the electric-motor-driven mode. Starting from the instantaneous position of the hybrid vehicle, the route is examined in an anticipatory manner with respect to such a route section, wherein the threshold value is adapted when such a route section was recognized and a driving through the route section in the electric driving mode would likely lead to a lowering of the state of charge of an electric energy accumulator into a critical state of charge range.
