On/off semi-active suspension control

机译:开/关半主动悬挂控制

摘要

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.
