Abstract

A method for operating a hybrid drive of a motor vehicle in particular. An internal combustion engine is connected to a generator via a force-conducting connection. In a learning mode, the generator is operated as a motor and drives the internal combustion engine. In this learning mode, a so-called zero quantity calibration is performed.
