The invention relates to a method for diagnosing an operating status of a drive device (5,7) in a drive system (1), particularly of a motor vehicle (2), having at least two drive devices (4), particularly an electric motor (8) and an internal combustion engine (6), and at least one clutch (17) which couples the drive devices (4) in an adjustable manner. According to the invention, target rotational speeds of the drive devices (4) are adjusted to predetermined values, and the operating status is determined from the arising actual rotational speed of the drive device (5,7). The invention further relates to a diagnostic device and a drive system (1). |
