Disclosed is a method for managing the starting of a combustion engine of a hybrid drive system including a combustion engine and an electric machine, as well as a drive shaft, the electric machine producing torque to start the combustion engine and drive the drive shaft at least during an initial phase of the start. In a transient starting phase, the combustion engine drives the drive shaft and the electric machine is stopped. The electric machine is regulated, during the initial phase and transient phases, with a first engine speed setpoint. The transient phase begins when the drive shaft reaches the first engine speed setpoint and remains steady. Torque control produced by the electric machine during the transient starting phase being configured so that the electric machine is stopped as soon as the control determines that the torque produced by the electric machine is tending toward zero torque.

Method for managing a transient phase of the starting of a heat engine by an electric motor

A starting assistance method and device for an internal combustion engine supplied with a fuel that may contain ethanol, and including a fluid connection pipe between an intake manifold and a braking assistance device. The method including determining the engine temperature, determining the outdoor air temperature, blocking the pipe between the intake manifold and the braking assistance device for a given duration during a phase of starting the engine when the temperature of the engine is lower than a first threshold value and the outdoor air temperature is lower than a second threshold value, and freeing the pipe between the intake manifold and the braking assistance device when the engine is rotating autonomously.
