Document Type and Number:
Japanese Patent JP3374208
Kind Code:
B2
Abstract:
A suspension control system for use with shock absorbers provided between sprung and unsprung masses of an automotive vehicle at the positions of the respective vehicle road wheels for providing variable damping force characteristics. Sprung mass vertical velocities at the respective road wheel positions are derived from a sensed sprung mass vertical behavior. Relative velocities between the sprung and unsprung masses at the respective road wheel positions are derived from the sensed sprung mass vertical behavior with the use of a predetermined transfer function including terms related to damping coefficients of the respective shock absorbers. A control unit is provided for producing control signals based on the derived sprung mass vertical velocities and the derived relative velocities to control the damping force characteristics of the respective shock absorbers. Damping coefficients of the respective shock absorbers are determined based on the corresponding control signals. The terms related to the damping coefficients of the respective shock absorbers are varied according to the determined damping coefficients.
