Abstract (en)
[origin: WO2018041586A1] The invention relates to a method for determining a coupling state (128a - 138a) of a drive train (2) of a motor vehicle (1) coupled to a clutch (4) on an internal combustion engine (112). Said method comprises the following steps: detecting the temporal course of a rotational speed (n) correlated to the rotational speed (nΒΚΜ) of the internal combustion engine (112); detecting at least one speed pattern (128 -138), produced by the internal combustion engine (112), from the temporal course of the rotational speed (nΒΚΜ), that has an oscillation (O) with at least one amplitude (A) superimposed over the temporal course of the mean value (DMD) of the rotational speed (nΒΚΜ), then it is closed in a coupling state (128a - 138a) when within a time interval (Δt), a characteristic change of the rotational speed (nΒΚΜ) and a characteristic behavior of the amplitudes (A) is detected. Furthermore, the invention relates to a corresponding computing unit (118) which is configured to carry out the method, to an electric machine comprising the computing unit and to a corresponding computer program for carrying out said method.
