Abstract

A method for operating a hybrid drive device, which includes a first drive unit and a second drive unit is disclosed, wherein a drive torque of the hybrid drive device is produced only by means of the first drive unit in a first operating mode and is produced jointly by the first drive unit and the second drive unit in a second operating mode, and wherein an actual rotational speed of the second drive unit is brought into line with a target rotational speed upon a switchover from the first operating mode to the second operating mode. In order to bring the actual rotational speed into line, a target rotational speed gradient is determined and a target torque determined on the basis of the target rotational speed gradient is set at the second drive unit.
