  • Method for controlling motion using a two-stage adjustable damper
    Patent number: 5732370
    Abstract: The relative motion and force between two interconnected elements can be controlled by a semi-active two-stage adjustable damper to maximize isolation between the elements, while minimizing the instances of the motion exceeding acceptable limits. An algorithm determines when to apply the high force state of the damper to provide excellent isolation from input vibration and shocks. The dampers and control algorithms are useful in primary vehicle suspension systems, cab mounts, seat mounts and engine mounts.
    Type: Grant

    Abstract: The relative motion and force between two interconnected elements can be controlled by a semi-active damper to minimize the instances of the motion exceeding acceptable limits, while maximizing isolation between the elements. Applying an algorithm to the control parameters of the damper provides excellent isolation from input vibration and shocks. The dampers and control algorithms are useful in primary vehicle suspension systems, cab mounts, seat mounts, and engine mounts.
