Estimating the term…
The invention relates to a method for controlling an operating characteristic (for example ground clearance or acceleration) of a vehicle (100) resting on a contact surface (200) by means of at least one landing gear (150) comprising means of actuating (160) adapted to vary a behaviour of the landing gear when the latter is in contact with the contact surface, whereby the said method makes the operating characteristic of the vehicle dependent upon a given set-point by generating a command intended for the means of actuating as a function of a difference (ε) between the operating characteristic and the set-point. According to the invention, the control system comprises the use of an estimation (Pest) of a load (P) seen by the landing gear to generate a modification of the command so as to minimise a variation in the deviation caused by a variation in the load.
