Patent ID: 6889645

Claim:
A method for starting a hybrid drive including a battery, an internal combustion engine, and at least two electric machines including at least one first electric machine and at least one second electric machine, the method comprising: coupling the at least one first electric machine, which is used to start the internal combustion engine, to the internal combustion engine at a beginning of a starting phase, before an actual starting of the internal combustion engine, while at least one second electric machine is brought to a specifiable rotational speed in a state that is uncoupled from the internal combustion engine and while electric power is being supplied from the battery; switching the at least one second electric machine to a generator operation at a point in time; supplying an electric power generated by the at least one second electric machine in the generator operation after reaching the specifiable rotational speed to the at least one first electric machine; and using the at least one first electric machine to start the internal combustion engine; wherein the specifiable rotational speed of the at least one second electric machine is specified as a function of a detected battery state.
