Abstract

A method for operating a drive device of a motor vehicle, which includes at least one internal combustion engine and at least one electric machine, a driving resistance, in particular an uphill gradient, being ascertained and the internal combustion engine being operated as a function thereof. The internal combustion engine is operated as a function of a driving resistance to be expected, which is determined as a function of an instantaneous driving resistance. A drive device for a motor vehicle is also described.
