Patent ID: 7510500

Claim:
A method for controlling a drive ( 16 ) of a motor vehicle having an internal combustion engine ( 10 ) and an electric motor ( 24 ), a main transmission ( 16 ) having an output shaft ( 18 ), which is connected to a driveshaft ( 19 ) of the motor vehicle, and an input shaft ( 14 ), which is connected to the internal combustion engine ( 10 ), the electric motor ( 24 ) being coupled to the input shaft ( 14 ) or the output shaft ( 18 ) of the main transmission ( 16 ) by means of an intermediate transmission ( 22 ) having at least two transmission ratio steps, where, to accelerate the motor vehicle from rest, the drive is initially effected solely by the electric motor ( 24 ), the intermediate transmission ( 22 ) being in its lowest transmission ratio step, and the provision of drive then being taken over by the internal combustion engine ( 10 ) before a shift operation in the intermediate transmission ( 22 ), characterized in that an energy store which is connected to the electric motor ( 24 ) is intermediately discharged, the electric motor ( 24 ) is operated in a regenerative mode, the electric motor ( 24 ) is operated in a booster mode and the like only in at least the second transmission ratio step of the intermediate transmission ( 22 ).
