Method for controlling the electrical power supply of solenoid fuel injectors for a hybrid motor vehicle comprising on the one hand an internal combustion propulsion engine (MCI) and on the other hand an electric motor (ME), said hybrid motor vehicle being equipped with a first electrical network powered under a first DC voltage (V1) and in particular intended to power an engine controller of the internal combustion propulsion engine (MCI) and with a second electrical network powered under a second DC voltage (V2), said second DC voltage (V2) being higher than the first DC voltage (V1) and in particular intended to power the electric motor (ME), said method comprises the following steps: i. connecting the second DC voltage (V2) to the electrical power supply of the solenoid fuel injectors, ii. reading the value of the second DC voltage (V2m), and reading an engine speed (N) of the internal combustion propulsion engine (MCI), reading a temperature of a coolant of the internal combustion propulsion engine representative of a temperature (Tm) of said internal combustion propulsion engine (MCI), and reading an injection pressure (Pm) upstream of the solenoid fuel injectors, iii. adapting drive parameters of the solenoid fuel injectors on the basis of the value (V2m) read in step ii, of an engine speed (N) of the internal combustion propulsion engine (MCI), of the temperature (Tm) of the internal combustion propulsion engine (MCI) deduced from the read temperature of the coolant of the internal combustion propulsion engine (MCI) and of the injection pressure (Pm) upstream of the solenoid fuel injectors, iv. driving the solenoid fuel injectors by means of the second DC voltage (V2) with: iv.a. no modification of the drive parameters of the injectors in the case where the value (V2m) is higher than a threshold value, and iv.b. modification of at least one of the drive parameters of the injectors in the case where the value (V2m) is lower than the threshold value. i. connecting the second DC voltage (V2) to the electrical power supply of the solenoid fuel injectors, ii. reading the value of the second DC voltage (V2m), and reading an engine speed (N) of the internal combustion propulsion engine (MCI), reading a temperature of a coolant of the internal combustion propulsion engine representative of a temperature (Tm) of said internal combustion propulsion engine (MCI), and reading an injection pressure (Pm) upstream of the solenoid fuel injectors, iii. adapting drive parameters of the solenoid fuel injectors on the basis of the value (V2m) read in step ii, of an engine speed (N) of the internal combustion propulsion engine (MCI), of the temperature (Tm) of the internal combustion propulsion engine (MCI) deduced from the read temperature of the coolant of the internal combustion propulsion engine (MCI) and of the injection pressure (Pm) upstream of the solenoid fuel injectors, iv. driving the solenoid fuel injectors by means of the second DC voltage (V2) with: iv.a. no modification of the drive parameters of the injectors in the case where the value (V2m) is higher than a threshold value, and iv.b. modification of at least one of the drive parameters of the injectors in the case where the value (V2m) is lower than the threshold value. iv.a. no modification of the drive parameters of the injectors in the case where the value (V2m) is higher than a threshold value, and iv.b. modification of at least one of the drive parameters of the injectors in the case where the value (V2m) is lower than the threshold value. <EOS>
