Abstract
A control system for a hydraulic suspension on a road vehicle comprises a common hydraulic connection for the suspensions of the wheels in a group, the vehicle being supported on a plurality of such wheel groups. Each said wheel group has a control valve for regulating fluid flow between its common hydraulic connection and a pressure source. The system includes means for generating first electrical signals corresponding to the vertical accelerations of the respective groups, means responsive to the first signals for generating second signals corresponding to the calculated vertical displacements of the respective wheel groups as a result of their vertical accelerations, means for generating third electrical signals corresponding to measured vertical displacements of the wheel groups, and means, responsive to differences between corresponding ones of the second and third signals for operating the respective control valves.
