Title: METHOD FOR CONTROLLING THE INCLINATION OF A TILTING VEHICLE BY ACTING ON A HYDROPNEUMATIC SUSPENSION DEVICE
Abstract:
A method for controlling the inclination of a tilting motor vehicle (V) having an axle unit (T1) comprising two wheels (RD, RG) and a hydropneumatic suspension device (DS1) comprising two dampers (AMD, AMG) coupled to the wheels. This method comprises a step that involves determining the current speed and inclination of the vehicle (V), then, if the current speed is less than a first threshold, acting on a hydraulic circuit linking the two dampers (AMD, AMG) together, in order that it blocks them in the current states of same, and, if the current speed is greater than the first threshold, determining if the difference between the current inclination and the necessary inclination is greater than a second threshold, and, if so, acting on the hydraulic circuit in order that it prevents the damper located on the current inclination side from reaching a chosen state corresponding to a chosen inclination greater than or equal to the current inclination.
