摘要:
The invention relates to a method for managing the power of a hybrid vehicle selectively driven by an electric motor and a heat engine, the electric motor being supplied with power by a power storage unit capable of being recharged by the heat engine, wherein according to the method the level of charge of the power storage unit is monitored so as to select the mode in which the vehicle is driven by the heat engine or that in which the vehicle is driven by the electric motor, said method including the steps of: determining a travelling profile of the vehicle associated with a path of said vehicle; and determining (36), according to said travelling profile, a threshold level of charged (S2), referred to as authorised threshold, below which the mode in which the vehicle is driven by the heat engine is activated.

The invention relates to a method and a device for controlling an engine operating with direct fuel injection, notably direct petrol injection, into a combustion chamber (3) of the engine. According to the invention: - an engine operating phase is determined, - the fuel is heated before it is introduced into the combustion chamber (3), according to said phase. The invention also relates to the combination of such a control device with an engine fuel supply circuit.
摘要:
Method for managing the speed of a hybrid vehicle comprising: - an electric motor (3), - a combustion engine (4), and - a clutch system (7) selectively coupling at least the electric motor (3) to driven wheels (2) of the vehicle, in which method: - absence of a demand to accelerate the vehicle is detected, and - using only the electric motor (3), the speed of the vehicle is maintained about at least one given setpoint value.
摘要:
Method for cutting off an electric motor (3) of a hybrid vehicle that further comprises a combustion engine (4), in which method: - the magnitude of a parameter indicative of the speed of the electric motor (3) as delivered by a sensor is compared against a predefined threshold value, and - the electric motor (3) is cut off when the value delivered by the sensor is below said threshold value.
摘要:
The invention relates to a method for controlling the operation of a vehicle engine (1) using error parameter values that are updated during the normal operation of the engine. Said error parameters relate to an opening of an intake-gas valve (21) and/or injectors (22) of the engine. New values are calculated for the error parameters according to an engine manifold pressure and/or an oxygen content of an exhaust gas of said engine. In a preferred embodiment of the invention, the new error parameter values are obtained using a recursive Kalman filter.

The invention mainly relates to a method for determining the mass flow rate (D 1 ) of air entering the intake manifold (3) of an internal combustion engine (2) provided with an exhaust-gas recirculation system (10), wherein said intake manifold (3) has a water-cooled air exchanger (6) built therein, the method being characterized in that it includes at least the steps of: determining the mass flow rate (D 2 ) of the recirculated gases (D 2 ) entering the intake manifold (3); determining the flow rate (D 3 ) of gas entering the intake manifold (3) using the Saint-Venant formula; and determining the mass flow rate (D 1 ) of air entering the intake manifold (3) by means of the difference between the mass flow rate (D 3 ) of gas entering the intake manifold (3) and the mass flow rate (D 2 ) of the recycled gas entering the intake manifold (3). The invention also relates to a device implementing said method.
