Beschreibung
Zusammenfassung:	A method for controlling an electrical assembly for a hybrid motor vehicle comprising a hybrid transmission gearbox, a high-voltage electrical network (1) comprising a bank of electrical accumulators (13), a high-voltage alternator-starter connected to an inverter (11), an electrical machine connected to another inverter (10), the hybrid motor vehicle further comprising a low-voltage electrical network (14, 17), and a DC-DC converter (12) able to power, from the high-voltage network (1), the low-voltage electrical network (14), the method comprising a step (21) of detecting a change of mode or of gear on said gearbox, requiring the opening of the battery relays, the method being characterised in that, when such a change of gear or of mode is detected, it further comprises: - a step (22) of acquiring voltage and current values at the terminals of the DC-DC converter (12); - a first step (23) of computing the input power of the DC-DC converter (12) as a function of the acquired values of the voltages and currents; - a second step (24) of computing a minimum power value as a function of said input power and of a correction value; - a step (25) of controlling the DC-DC converter (12) so as to supply said minimum computed power as output.
