Abstract: A vehicle suspension system has at least one leveling device with a leveling sensor on each side of the vehicle. Leveling action is initiated when a sensor indicates height out of a dead band around the calibrated level for the sensor. Once initiated, leveling action occurs independently for all devices in closed loop to target levels, different for intake and exhaust, which allow overshoot to a common intermediate level, the intermediate level allowing settling to the calibrated level. Order of leveling is rear first with intake before exhaust and then front with exhaust before intake to prevent the rear from falling below the front. Leveling is prevented when the vehicle is not moving but has moved since the last opening of one or more selected vehicle doors.

Abstract: An active vibration control (AVC) system is disclosed for attenuating vibrational frequency components generated by an engine and transferred through an engine mounting unit to vibrate a motor vehicle body. The motor vehicle is characterized by sprung mass and unsprung mass natural resonant frequencies at which the body also vibrates when the vehicle is driven over an undulating road surface. The AVC system operates by generating input signals representing different vibrational frequency components generated by the engine based upon sensed changes in engine rotation. Each input signal is filtered by an adaptive filter to produce a respective output signal. The output signals are summed to produce a canceling signal for driving an inertial mass shaker mounted on the body. The shaker inversely vibrates the body with respect to the different vibrational frequency components transferred to the body from the engine. A vibration sensor mounted to the body proximate the shaker monitors body vibration and develops a representative error signal. Vibrational components associated with the sprung and unsprung mass natural resonant frequencies are substantially removed from the error signal using a dual notch filter. The filtered error signal is then used to adjust the filtering characteristics of the adaptive filter to minimize vibration of the body caused by the different vibrational frequency components transferred to the body from the engine.

Abstract: A full vehicle suspension control for a wheeled vehicle includes a suspension actuator and an absolute accelerometer at each corner of the vehicle body. The actuators are controlled in response to vehicle body pitch and roll velocity signals which are derived from nominally vertical acceleration signals from the accelerometers by first deriving vehicle body pitch and roll acceleration signals and then integrating these signals into vehicle body roll and pitch velocity signals. The process of converting the body corner acceleration signals to pitch and roll acceleration signals reduces any non-vertical error of the signals before integration to reduce saturation of the integrator.

Abstract: 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.

Abstract: A vehicle has a real time suspension control which requires, as inputs, a set of absolute body modal velocity signals. Accurate estimates of these signals are derived from relative position sensors at the body suspension points by converting the relative vertical position signals from these sensors to relative body modal (e.g. heave, pitch and roll) velocity signals and passing each of these signals through a second order low pass filter including an additional phase inversion for compensation of the 180 degree filter phase lag. Thus, the necessity of absolute body accelerometers is eliminated, for a significant cost reduction. In a vehicle having significant front to rear flexing or flexing within the front or rear suspension that can affect the accuracy of the estimated absolute body roll velocity, the normal roll velocity transformation equation is modified to include only the front or the rear pair of relative velocity signals.

Abstract: A full vehicle suspension control derives the vertical wheel and vertical body corner velocities at each corner of the vehicle body and derives therefrom a set of at least three body state velocity variables descriptive of vertical body motions and attitude. These body state velocity variables may be the body heave, roll and pitch velocities or a plurality of the vertical body corner velocities. The suspension control computes desired forces between each body corner and its corresponding wheel from a linear combination of the vertical wheel velocity of that wheel and the body state velocity variables and derives control signals from the desired forces and, in a semi-active system, the sign of demand power. The control signals are applied to vertical force actuators connected to exert vertical forces between the vehicle body and wheel at the vehicle body corners and capable of response at frequencies sufficient to control wheel as well as body vibrations in real time.
