A method for controlling the electric drive train (1) of a vehicle, said train comprising: - a polyphase electrical machine (4), comprising a stator electrical winding having a plurality of coils each forming an electrical phase of the stator, - a self-contained electric power source (2) powering the stator electrical winding of the machine (4), and - a switching system (3) interposed between the self-contained electric power source (2) and the stator electrical winding and comprising a plurality of switching cells (10), method which involves: - applying a control to the switching system (3) in order to operate the electric drive train (1) according to a predefined mode, - detecting a difference between the actual operating mode of the drive train (1) and the predefined operating mode, and - applying an auxiliary control to the switching system (3), said auxiliary control short-circuiting only a portion of the coils of the stator electrical winding such that the voltage at the terminals of each non-short-circuited coil is lower than a given threshold value.
