Abstract
The invention relates to a method for synchronising the common speed (ω p) of two concentric primary shafts () of a hybrid transmission in a hybrid operating mode wherein said two shafts are rotatably connected by a first coupling means (), with the speed (ω s) of a secondary transmission shaft () comprising at least one idler pinion for allowing the coupling of one of said pinions () to the shaft () thereof by closing a second coupling means () that does not have mechanical synchronisation bodies, the torque (Te) of the electric machine being temporarily reduced during the synchronisation phase in order to meet the conditions of a perfect coupling when the value thereof caps at an upper limit value (T) or a lower limit value (T).
