Abstract:
1. Suspension control method for a motor vehicle body on its wheels, having a computer (CSS) adapted to calculate a control magnitude (ER) for an actuator (M) of at least one variable damper (AM) of the suspension (S) as a function of at least one modal setpoint force of the damper, calculated as a function of at least an absolute body modal speed V mod determined on the vehicle, wherein the method comprises: detecting the wheel displacement with respect to the body for each wheel, calculating, as a function of at least the displacement measurements of the wheels provided by said displacement sensors, a variable damping modal gain b calculating the setpoint force of the damper as a function of the first setpoint modal force F wherein the mode is at least one among vertical heave b and wherein the variable damping modal gain comprises at least one reset multiplier coefficient b the reset multiplier coefficient b the reset multiplier coefficient b the reset multiplier coefficient b where k k k I I MREF is a constant reference mass, I I MSUS is a vehicle sprung mass, calculated as a function of at least the displacements, k k k
