A vehicle suspension device for controlling the vertical deflection between a suspended mass and a non-suspended mass, including an elastic link mounted between the suspended mass and the non-suspended mass, the said elastic link embodying a spring, a reversible electric actuator acting in parallel with the spring for controlling the relative-deflection movements between suspended mass and non-suspended mass, Zcr being the distance between the suspended mass and the non-suspended mass, and means for controlling the electric actuator, from an observed variation of the distance Zcr between the suspended mass and the non-suspended mass due to a deflection of the elastic link, in order that the electric actuator develops a force F having a mass compensation component F1=Ca.Mr.Acr oriented like the acceleration Acr of the deflection of the non-suspended mass with respect to the suspended mass, with Mr being the non-suspended mass and Ca a coefficient, and having a damping component F2=-Cv.Vcr opposing the speed Vcr of the said deflection, Cv being a coefficient.
