Abstract
A method for controlling a drive () of a motor vehicle having an internal combustion engine () and an electric motor (). A main transmission () having an output shaft () is connected to a driveshaft () of the motor vehicle, and an input shaft () is connected to the internal combustion engine (). The electric motor () is coupled to the input shaft () or the output shaft () of the main transmission () by an intermediate transmission () having at least two transmission ratio steps. In order to accelerate the motor vehicle from rest, the drive is initially effected solely by the electric motor () with the intermediate transmission () in its lowest transmission ratio step. The drawing is then taken over by the internal combustion engine () before a shift operation in the intermediate transmission (). In this case, the intermediate transmission () is preferably a claw shift transmission.
