A vehicle has an internal combustion engine, an electric drive device and a transmission with two component transmissions that can be selected simultaneously. Torque can be transmitted from the electric drive device and/or the internal combustion engine to at least one axle of the vehicle, and a torque can be transmitted from the axle to the electric drive device and/or the internal combustion engine. The internal combustion engine is adjusted from a deactivated state to an energized state. Torque is transmitted to the internal combustion engine by the axle and/or the electric drive device via one of two shifting elements to increase rotational speed of the internal combustion engine. The internal combustion engine is adjusted to a target rotational speed via one of the shifting elements. The connection between the internal combustion engine and the axle is produced via one of the shifting elements upon reaching the target rotational speed.
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:
