초록 ▼

A controlled suspension for a wheeled vehicle includes a damper between the vehicle body and wheel, the damper being switchable, at a frequency sufficient for the control of resonant wheel vibrations, between a first mode of operation characterized by a high damping force and a second mode of operation having a low damping force. A control repeatedly derives from sensed vehicle suspension related operating variables desired force to be applied between the body and wheel in order to produce a desired suspension behavior determines whether that force result in active or dissipative suspension power. The control further stores a threshold and controls the damper for each derivation so that (1) the damper operates in its second mode of operation when the desired force would produce active power, (2) the damper operates in its first mode of operation when the desired force exceeds the threshold and would produce dissipative power, and (3) the damper operates in its second mode of operation when the desired force is less than the threshold and would produce dissipative power.

A controlled suspension for a wheeled vehicle having a body suspended by at least one suspension spring on an unsprung, road contacting wheel, the suspension comprising, in combination: a damper connected to apply a damping force between the body and wheel, the damper including apparatus providing a first mode of operation characterized by a high damping force and a second mode of operation having a low damping force and including a valve capable of switching the actuator between the first and second modes of operation at a frequency sufficient for control of resonant wheel vibrations; and control means effective to repeatedly derive from one or more sensed vehicle suspension related operating variables, at the rate sufficient to control resonant wheel vibrations, a desired force to be applied between the body and wheel in order to produce a desired suspension behavior and to further determine for each such derivation whether the application of the desired force would result in active or dissipative suspension power, the control means being further effective to store a threshold and to control the valve for each such derivation so that (1) the damper operates in its second mode of operation when the desired force would produce active power, (2) the damper operates in its first mode of operation when the desired force exceeds the threshold and would produce dissipative power, and (3) the damper operates in its second mode of operation when the desired force is less than the threshold and would produce dissipative power.
