PROCESS FOR MANAGING A TRANSITIONAL PHASE OF STARTING A THERMAL MOTOR BY AN ELECTRIC MACHINE

摘要

The present invention relates to a method for managing the starting of a heat engine of a hybrid drive system comprising a heat engine and an electric machine (BSG), as well as a motor shaft (X), the electric machine ( BSG) producing a torque to ensure the starting of the heat engine and drive the motor shaft (X) at least during an initial phase of starting, said method having a transient starting phase during which the heat engine drives the motor shaft (X) ) and at the end of which the electric machine (BSG) is stopped, the electric machine (BSG) being regulated, during the initial phase (ELEC) and during the transient phase, with a first engine speed setpoint (N_SP_IS), said phase transient starting when the motor shaft (X) reaches the first engine speed setpoint (N_SP_IS) in a stabilized manner, the control of the torque produced by the electrical machine (BSG) during said transient starting phase being configured so that the electric machine (BSG) is stopped therefore said control determines that the torque produced by the electric machine (BSG) tends towards zero torque.
