Patent ID: 7542838

Claim:
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.
