Abstract:
A method for monitoring an automated drive train of a motor vehicle, in particular of a passenger car. The drive train comprises a drive engine, a friction clutch arrangement and a multi-speed transmission. The friction clutch arrangement connects or disconnects the drive engine to/from the multi-speed transmission. The method comprises the step of determining at least one rotational speed parameter of the drive train; checking whether the rotational speed parameter is greater than a first threshold value for a first predetermined time interval, and initiating a measure in the drive train in order to lower the rotational speed parameter if the rotational speed parameter is greater than the first threshold value for the first predetermined time interval.
