1. A method comprising:
- a. equipping a vehicle with an electronic stability program (“
ESP”
) system having nominal threshold values (Sv) for triggering the ESP system at different known speeds;
b. acquiring in real time, on said vehicle in a rolling situation, at various moments, setpoint yaw angles (LC);
c. acquiring in real time, in a rolling situation, at the same moments, the yaw angles measured on the vehicle (LM);
d. measuring the ESP triggering threshold (St) at these various moments;
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);
f. modifying the nominal threshold values (Sv) by a percentage that is proportional to the consumption values (Cesp); and
g. adjusting one or more characteristics of a vehicle component based on the modified nominal threshold values.

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).
