する電子制御シヨツクアブソーバ装置。 It has a shock absorber whose damping force can be electrically varied and a means for detecting relative displacement between the sprung portion and the unsprung portion of the vehicle body, and when the vehicle body is displaced in the direction away from the neutral position of the relative displacement between the sprung portion and the unsprung portion. In a shock absorber device that controls the damping force to be soft and hard when the damping force is displaced in the direction approaching the neutral position/The cutoff frequency of the detection signal of the relative displacement detection means is from twice to three times the unsprung resonance frequency. An electronically controlled shock absorber device characterized in that the shock absorber device passes through a double low-pass filter and performs the control based on the amount of relative displacement after passing through.
