Abstract: The invention relates to a method for controlling the start-up of a vehicle comprising an engine start-stop system, wherein the method includes the actuation of the start-up of the vehicle. The invention is characterized in that the method comprises the steps: an autonomous engine state is indicated in response to the simultaneous occurrence of (i) the injection of fuel into the combustion chambers of the engine and (ii) an engine speed above a pre-defined threshold S1 which is equal to an engine speed that cannot be achieved without combustion in the combustion chambers during the start-up of the vehicle; and, in response to the aforementioned autonomous engine state indication, the closing of a clutch is controlled according to a pre-defined engine speed set value in order to control the engine speed to the pre-defined set value.

Abstract: The invention relates to a method for controlling the start-up of a vehicle comprising an engine start-stop System, said method including the actuation (52) of the start-up of the vehicle. The invention is characterised in that the method also comprises the following steps: an autonomous engine state is indicated (62) in response to the simultaneous occurrence of (i) the injection of fuel into the combustion chambers of the heat engine and (ii) a heat engine speed above a pre-defined threshold S1, said threshold SI being equal to an engine speed that cannot be achieved without combustion in the combustion chambers during the start-up of the vehicle; and, in response to the aforementioned autonomous engine state indication, the closing of a clutch is controlled (66) according to a pre-defined motor speed set value in order to slave the motor speed to said pre-defined set value.
