A vehicle with soft hydropneumatic suspension of the body from the wheel base including facilities for suppressing roll-out on turns without binding free independent movement of the wheels. The roll-out is suppressed by the cooperation of a pendular hydraulic controller mounted on the body and hydraulic actuators, which suspend the body resiliently from the wheel base, and the spring accumulator of the hydropneumatic suspension. Pressure is supplied to the accumulator and to the actuators from an hydraulic power source. The actuators exert a force couple on the body. The pendular controller has a pendulum which, responsive to the movement of the body, reacts in the controller so that the controller varies the couple produced by the actuators in such a sense and with such magnitude as to suppress roll-out on turns. The actuators also provide integral leveling or height control of the body. A significant feature is that one of the actuators has a pair of pressure chambers and the other, only one chamber. The force couple is exerted by the force produced by the pressure in one of the pair of chambers and in the one chamber. Integral leveling is provided by the forces exerted by the pressure in the other of the pair of chambers and in the one chamber.
