The invention relates to an apparatus and a method for estimating a suspension stroke-related value. And a control means (30) that controls the control current supplied to the dampers (24FL-24RR) that generate a damping force on the basis of the control current. The coefficients of two functions are determined on the basis of the relationship between the control current and the coefficients of the two functions in which the equivalent damping coefficient (ce (I)) and the equivalent spring constant (ke (I)) of each suspension, which change in accordance with the control current and the frequency of the relative vibration, are subjected to sign regression, and the control current supplied to the damper. The relative displacement (zsi) or the relative velocity (dzsi) between the sprung and the unsprung is calculated on the basis of two functions in which the vertical acceleration on the sprung detected by the detection devices (32FL-32RR) and the coefficient are determined.
