Patent ID: 8360183

Claim:
A method for operating a drive system for a motor vehicle that has an electric drive device, an internal combustion engine and a transmission connected to the internal combustion engine, the transmission having at least two component transmissions on which different transmission ratios can be selected at the same time, each component transmission having a shifting element for connecting the component transmission to the internal combustion engine, the internal combustion engine and the electric drive device being connected to the transmission so that a torque can be transmitted from the electric drive device and the internal combustion engine to at least one drive axle of the motor vehicle, and a torque can be transmitted from the at least one drive axle to the electric drive device and the internal combustion engine, the internal combustion engine being adjustable from a deactivated state to an energized state, the method comprising: transmitting a torque to the internal combustion engine by the drive axle or the electric drive device via one of the two shifting elements to increase the rotational speed of the internal combustion engine; adjusting the internal combustion engine to a target rotational speed via one of the two shifting elements; and connecting the internal combustion engine and the drive axle via one of the two shifting elements when the target rotational speed is reached.
