The invention relates to a method for controlling a hybrid drive train (10) of a motor vehicle, wherein the hybrid drive train (10) comprises an internal combustion engine (12), an electric machine (26) used to drive the motor vehicle, a dual clutch transmission having a first friction clutch (16) and a first partial transmission (20) associated with the first friction clutch (16) and the second friction clutch (18), and a second partial transmission (22) associated with the second friction clutch (18) and an electrical starter motor (30) for the internal combustion engine (12). The electric machine (26) is connected to an input of the second partial transmission (22). Starting from a state in which the motor vehicle is stationary, in which the internal combustion engine (12) is stopped, in which at least the second friction clutch (18) is opened and in which a starting gear step (2) is inserted into the second partial transmission (22), the method comprises the following steps: detecting (S1 - S5) whether a driver is experiencing problems; if the driver is experiencing problems, switching (S12) the second partial transmission (22) into a neutral state, closing (S13) the second friction clutch (18), starting (S14) the internal combustion engine (12) using the electric machine (26), opening (S15) the second friction clutch (18) and inserting the starting gear step (2) into the second partial transmission (22), and subsequently asking (S6) if starting is desired; and if the driver is not experiencing problems, asking (S6) which starting is desired.
