Inflation method for a vehicle provided with a centralised tyre inflation system

A method for adjusting the tyre pressure of a vehicle by means of a central tyre inflation system, CTIS;

• the vehicle comprising at least a first group and a second group of tyres, each group comprising at least one tyre;
• each group having an initial pressure;
• a predetermined target pressure corresponding to each group;
• the method involving carrying out a sequence for adjusting the pressure of each group from the initial pressure to the target pressure;
• the sequence comprising at least one increment for each group;
• each increment being defined by an air volume to be added to the tyres of the group;
• the sequence involving adjusting the pressure of the groups increment by increment, by switching to another group once one increment has been carried out until each group has reached its target pressure,
• wherein a number of increments of a group is determined from a pressure difference between the target pressure and the initial pressure of the group:
• either by dividing the pressure difference by a maximum pressure variation per increment;
• or by converting the pressure difference into an adjustment time and dividing this time by a maximum increment time.
