Patent ID: 8179070

Claim:
A method of preparing a reversible electrical machine with a phase for starting a thermal engine of a vehicle equipped with an automatic starting/stopping system, the reversible electrical machine comprising a rotor coupled to said thermal engine, said method comprising the steps of detecting an action prior to a start instruction to start the thermal engine, and applying an electrical magnetization current to the reversible electric machine as soon as said prior action is detected; wherein said prior action is a pressing of a control pedal driving the thermal engine; wherein said pedal is a clutch pedal and/or an accelerator pedal; wherein said reversible electric machine further comprises at least one sensor, said method further comprising the step of detecting said pressing of said pedal using said at least one sensor, wherein said detection of a first pressing level triggering the application of said magnetization electric current to the rotor of the reversible electrical machine, and the detection of a second pressing level triggering said start instruction; wherein said first pressing level is at least equal to approximately 10% of a total pressing and the said second pressing level is at least equal to approximately 90% of the total pressing.
