A method to control an active shock absorber of a road vehicle. The active shock absorber is part of a suspension connecting a frame of the road vehicle to a hub of a wheel and has: a first element, which defines an end of the active shock absorber, a second element, which defines another end of the active shock absorber and is mounted so as to slide relative to the first element; and an actuator, which is configured to generate a force, which is applied between the two elements. The control method comprises the steps of: determining a vertical acceleration of the hub; determining a speed of translation between the two elements of the active shock absorber; determining a target force for the actuator of the active shock absorber based on the vertical acceleration of the hub and based on the speed of translation between the two elements of the active shock absorber; and controlling the actuator () of the active shock absorber so as to pursue the target force.

Method to control active shock absorbers of a road vehicle. Each active shock absorber is part of a suspension connecting a frame to a hub of a wheel and is provided with an actuator. The control method comprises the steps of: determining a longitudinal acceleration and a transverse acceleration of the road vehicle; establishing a desired roll angle based on the transverse acceleration; and establishing a desired pitch angle based on the longitudinal acceleration.

Method to control active shock absorbers of a road vehicle. Each active shock absorber is part of a suspension connecting a frame to a hub of a wheel and is provided with an actuator. The control method comprises the steps of: determining a longitudinal acceleration and a transverse acceleration of the road vehicle; establishing a desired lowering of a centre of gravity of the road vehicle depending on the longitudinal acceleration and on the transverse acceleration; and controlling the actuator of each active shock absorber so as to obtain the desired lowering of the centre of gravity.
