1. Method of adjusting an electronic stability program for a motor vehicle, characterized in that it comprises the following steps:
- step a;
equipping a vehicle with an ESP system having nominal threshold values (Sv) for triggering the ESP system at different known speeds,step b;
acquiring in real time, on said vehicle in a rolling situation, at various moments, setpoint yaw angles (LC),step c;
acquiring in real time, in a rolling situation, at the same moments, the yaw angles measured on the vehicle (LM),step d;
measuring the ESP triggering threshold (St) at these various moments,step e;
establishing a curve of consumption values (Cesp) as a function of time, said curve being representative of the differences (dCM) of the measured yaw angles and the setpoint yaw angles (dCM=LM-LC) versus the measured triggering threshold values (St),step f;
modifying the nominal threshold values (Sv) by a percentage that is proportional to the consumption values (Cesp).

Abstract
The invention relates to a method of adjusting an electronic stability program (ESP) for a motor vehicle. This method comprises various steps, including in particular: establishing the curve of the consumption values (Cesp) as a function of time, said curve being representative of the differences (dCM) of the measured yaw angles and the setpoint yaw angles (dCM=LM−LC) versus the measured triggering threshold values (St), modifying the nominal threshold values (Sv) by a percentage that is proportional to the consumption values (Cesp).
