Abstract: A hydraulic suspension system includes: a central control apparatus and height adjustment apparatuses respectively corresponding to wheels of a vehicle. The central control apparatus includes a housing and a moving member movably disposed in the housing and dividing the housing into a first region and a second region in a moving direction of the moving member. The first region includes a first chamber and a second chamber isolated from each other. The second region includes a third chamber and a fourth chamber isolated from each other. The first, second, third, and fourth chambers respectively communicated with the height adjustment apparatuses. The height adjustment apparatuses communicated with the first chamber and the second chamber correspond to wheels located on a first diagonal of the vehicle. The height adjustment apparatuses communicated with the third chamber and the fourth chamber correspond to wheels located on a second diagonal of the vehicle.
