特徴とするシヨツクアブソーバ装置。 A shock absorber whose damping force can be electrically varied; a relative displacement detecting means between an unsprung portion and an unsprung portion of a vehicle body; and a control circuit that issues a signal to the shock absorber to change the damping force in response to a signal from the relative displacement detecting means. In a shock absorber device consisting of
a low pass filter that passes a component near the sprung mass resonance frequency of the signal from the relative displacement detection means to the control circuit; and a high pass filter that passes a component near the sprung mass resonance frequency of the signal from the relative displacement detection means to the control circuit. and the control circuit softly controls the damping force when the output signal of the high-pass filter is less than a predetermined value and the output signal of the low-pass filter changes in a direction away from the neutral position. When the output signal of the high-pass filter is greater than a predetermined value, the damping force is switched to hard when the output signal of the high-pass filter changes toward the neutral position, and then the damping force is switched to hard when the high-pass filter output signal changes toward the neutral position. A shock absorber device characterized by being configured to softly control time damping force.
