Summary:The present invention relates to a method for detecting a malfunction of an electric driving unit and an apparatus for responding to the malfunction of the electric driving unit. The method comprises the steps of: determining a current characteristic curve (1) of the electric driving unit (S17); detecting a slope change of the current characteristic curve (1) at a first time point (t = n) (S33); comparing the slope change and a pre-configurable slope change range (S35, S39); and verifying the malfunction of the electric driving unit when the slope change is beyond the pre-configurable gradient change range (S45).
