Zusammenfassung:The invention concerns a method for starting an internal combustion engine of a hybrid vehicle comprising a starter, a DC-DC converter, and a low-voltage battery connected in parallel to said on-board network, said method comprising the steps of: -activating (E1) the starter, -comparing (E4) the supply voltage (Valim) of the on-board network with a first predetermined low threshold (S1), -opening (E5) a switch (COM) comprising at least one transistor to isolate the on-board network from said low-voltage battery and from the starter when said supply voltage (Valim) of the on-board network is less than or equal to said first predetermined low threshold (S1), said step of opening (E5) being followed by steps of: -deactivating (E6) said starter, -and closing (E7) said switch (COM).
