    摘要： A method for estimating the insulation resistance between a terminal of a battery (Batt) and an electrical earth, comprising: -connection of a measuring circuit (CM) to one terminal of the battery (Batt), said measuring circuit comprising a resistance (R) of known value and a capacitance (CE); and -application (1) of a known input signal having an input voltage (Ue). The method further comprises: -measurement (2) of an output voltage between the earth and a point (P) located between the resistance (R) of known value and the capacitance (CE); -determination (3) of a complex impedance of a dipole consisting of the capacitance (CE) and the insulation resistance (Risol) or determination of the parameters of a differential equation; and -determination (4) of the insulation resistance (Risol) from the parameters of the differential equation or said complex impedance.

    摘要： Electrical architecture of a hybrid motor vehicle comprising a combustion engine (19) driving an alternator (21) that recharges a low-voltage on-board battery (22) connected to the starter (24) of the combustion engine and to the vehicle on-board network (24), an electric traction machine (7) powered by a high-voltage traction battery (18), and a hybrid transmission (17) having coupling means (5) that can occupy at least a first position in which the combustion engine (19) is uncoupled from the drive train connecting the electric machine (7) to the wheels, a second position in which the wheels are driven by the combustion engine (19) with or without top-up from the electric machine (7), and a third position in which the combustion engine (19) and the electric machine (7) are coupled in such a way as to combine their respective torques, bound for the wheels. This architecture is characterized in that the combustion engine (19) and the alternator (21) constitute an electricity generator set capable of supplying the energy requirements of the traction electric machine (7) in electric mode.
