The invention relates to a strategy for operating an electrical machine (2) connected by a jaw clutch system (6) to the wheels (10) of a hybrid electric vehicle which implements a speed control method for controlling the electrical machine (2) with a synchronising speed set point value (18) in order to adjust with a margin the speeds of the two elements of the clutch (6) to be interconnected, in preparation for closing the clutch, this strategy being distinguished in that it prevents the control of the speed of the electrical machine (2) in preparation for closing the jaw clutch (6) from being implemented if the speed difference between the two elements of the clutch (6) is lower than a speed threshold and if, for this electrical machine (2), the difference between the speed set point value (18) and the actual speed (16) is higher than a speed threshold.
