A method of controlling a vehicle hybrid propulsion system is provided. The propulsion system includes an internal combustion engine, first and second clutches, an electric motor, and a gearbox having an input shaft and an output shaft connected to drive wheels. The method includes a first operating mode of starting the engine by the motor, a second operating mode of actuating a gear shift, and a third operating mode which actuates starting of the engine and the gear shift. The method includes passing from the first to the third operating modes even if starting of the engine has not been completed, or passing from the second to the third operating modes even if actuation of the gear shift has not been completed, so that the transition from one operating mode to another can be freely actuated at any time, depending upon operating conditions of the hybrid propulsion system.
