For the purpose of drive control for a hybrid vehicle, a journey route (FR1, FR2) to be taken which lies ahead is calculated between a current geographical starting position (AP) for the hybrid vehicle (FZ) and a geographical destination position (ZP) which is to be reached by the hybrid vehicle (FZ). Information relating to road and traffic situation is ascertained for the journey route (FR1, FR2) to be taken which lies ahead. On the basis of this information, a route segment (S1, S2,..., S8) which lies immediately ahead is determined from the journey route (FR1, FR2) to be taken which lies ahead. Information relating to driver, vehicle, road and/or traffic situation is ascertained for this current ascertained route segment (S1, S2,..., S8) which lies immediately ahead. On the basis of this information, the internal combustion engine (VM) and the electric motor (EM) are controlled when travelling on this route segment (S1, S2, ..., S8).
