Abstract
In a method for diagnosing an operating status of a drive device in a drive system of a motor vehicle having at least two drive devices configured as an electric machine and an internal combustion engine, and having at least one separating clutch which couples the drive devices in an adjustable way, setpoint rotational speeds of the drive devices are set to predetermined values and the operating status is determined from the resulting actual rotational speed of the one drive device.
