Abstract
A method for operating a hybrid drive system of a vehicle in which an internal combustion engine and/or at least one electrical machine drive the vehicle, the electrical machine being supplied with energy from an energy reservoir or the electrical machine supplying the energy reservoir with electrical energy, and an operating point of the hybrid drive system being set in the context of a predefined operating strategy which depends on minimization variables that take into account the fuel consumption of the internal combustion engine and the energy made available by the energy reservoir. In order to configure the operating strategy of the hybrid drive system in as variable a manner as possible, energy from an external energy source is delivered to the energy reservoir, the minimization variables to be taken into account as a result of the delivery of energy from the external energy source into the energy reservoir being evaluated in the operating strategy.
