This device is intended for a vehicle in which the wheels (1) are each equipped with a damper (2) and with a suspension spring (3); it comprises, for each wheel, an actuator (4) interacting with the spring, and provided with a position sensor (5), an electro-hydraulic interface (6) for controlling the actuator, this interface being connected to the actuator, to a hydraulic unit (8) of the vehicle and to a source of electrical energy, and a computer (7) for trim management, connected to the interfaces, and programed to take account of each parameter of the driving of the vehicle, especially its speed and the angle of its steering wheel; on the basis of these parameters, the computer controls the interfaces (6) and the actuators within the context of loops for slaving the latter to reference output travels, corresponding to maintaining the vehicle in predetermined trim stored in the memory of the computer. This trim system makes it possible to prevent rolling and pitching during the phases of acceleration, braking and cornering, without affecting the comfort of the occupants.
