Abstract
A method controls the startup of a heat engine of a hybrid power train of a vehicle. The power train includes the heat engine and an electric drive machine, two concentric main shafts coupled one to the heat engine and one to the electric machine, at least one step-down gear of each of the main shafts on a secondary shaft connected to wheels of the vehicle, and a coupling of the two main shafts. The method includes coupling the two main shafts, inhibiting fuel injection of the heat engine, launching the heat engine by the electric machine, synchronizing a speed of the heat engine and a speed of the electric machine without fuel injection, activating the fuel injection and turning off the electric machine and decoupling the two main shafts.
