An active, computerized, adaptive control system is discussed for the control of vehicle vibrations by means of adjustment of suspension parameters during the ride. The problem is subdivided into two basic parts. One, optimization of vehicle suspension parameters if forward speed, terrain statistics and vehicle descriptors are known a-priori. This information is developed off board and stored on board in the computer memory. Two, methods of evaluating terrain data received from sensors on board the vehicle and subsequently processing it for comparison with the stored data contained in the memory. Methods of signaling the selection of best parameters by means of amplifiers, solenoids and valves to the suspension system Conceptual design. The use of fluid suspension elements is shown to permit automatic height control static deflection control relative to payload together with dynamic deflection control based on root mean square values of the input displacements. The theoretical problem treatment refers to linear suspension systems subject to random inputs. Included is an analog computer program and results of trial runs. Author
