PROBLEM TO BE SOLVED: To provide a damper control device capable of restricting low frequency vibration of a sprung member of a vehicle.SOLUTION: A damper control device 1 for controlling damping forces of dampers D1, D2, D3 and D4 interposed between a sprung member B and unsprung members W1, W2, W3 and W4 of a vehicle includes: a sprung speed detecting section capable of detecting one or both of the roll speed Vr and the pitching speed Vp of the sprung member B; and a damper speed detecting section capable of detecting the stroke speed Vd, Vd, Vdand Vdof the dampers D1, D2, D3 and D4. The damper control device 1 obtains required damping force F1, F2, F3 and F4 of the dampers D1, D2, D3 and D4 based on the stroke speed Vd, Vd, Vdand Vd, and obtains damping force target values F1, F2, F3and F4of the dampers D1, D2, D3 and D4 based on one or both of the roll speed Vr and the pitching speed Vp and the required damping force F1, F2, F3 and F4 to control the damping force of the dampers D1, D2, D3 and D4. |
