Abstract

A method for operating a hybrid vehicle having a first driven axle (10) that can be driven exclusively electrically by at least one first electric machine (14) assigned to the first axle (10), and having a second driven axle (12) that can be driven by at least one second electric machine (16) assigned to the second axle (12) and/or by an internal combustion engine (15) assigned to the second axle (12). During each current driving cycle of the hybrid vehicle a kilometer reading/mileage reading, or a variable representing the kilometer reading/mileage reading, of the hybrid vehicle is determined, and an operating strategy is determined for a subsequent new driving cycle of the hybrid vehicle on the basis of the kilometer reading/mileage reading, or the variable representing the kilometer reading/mileage reading, of the previous driving cycle.
