The present disclosure relates to a method for operating a hybrid electric vehicle. According to the method, route information is received in the form of a plurality of parameter sets, each parameter set relating to a segment of the route (S1). Subsequently, the power demand for each segment is estimated (S3), and a portion of the amount of energy stored in the power storage device is allocated to at least one of the segments. Alternatively or additionally, an amount of energy to be transmitted into the electricity storage device is distributed to at least one of the segments (S4). Furthermore, at least one reference trajectory describing the energy state of the electrical storage device on the route is derived, said reference trajectory being derived from the energy distribution (S5). The operation of the hybrid electric vehicle is controlled according to a slope between the current energy state and an upcoming control point on the reference trajectory (S7). The invention further relates to a data processing
