A method for controlling a hydropneumatic suspension of a mobile crane having at least four wheels that are each allocated a spring cylinder, having at least four spring circuits in which at least one spring cylinder is incorporated in each case, each spring circuit being allocated a pressure measurement sensor and a path measurement sensor, in which signals of the pressure measurement sensors and of the path measurement sensors are processed by a control unit, and the spring cylinders are actuated. To optimize control of a hydropneumatic suspension for road travel operation of the mobile crane the mobile crane is levelled using preset suspension height set values of the spring circuits, then, in the control unit, on the basis of pressures detected by pressure sensors, pressure set values are calculated per spring circuit and pressures in the spring circuits are readjusted with the aid of pressure set values.
