To provide a vehicle active suspension device that facilitates adjustment of attenuation force of an attenuation force variable damper with respect to rotational behavior of a vehicle, can suppress adjustment cost and adjust the same with high completeness, and suppressing production cost.SOLUTION: A vehicle active suspension device has a roll suppression control portion 26 that computes a sprung roll angle and unsprung roll angle from a sprung vertical behavior of a vehicle detected by acceleration sensors 15, 16, and 17, and computes a roll attenuation force control value on the basis of a difference between the sprung roll angle and the unsprung roll angle, and a pitch suppression control portion 27 that computes a sprung pitch angle and an unsprung pitch angle from the sprung vertical behavior, and computes a pitch attenuation force control value on the basis of a difference between the sprung pitch angle and the unsprung pitch angle. On the basis of the roll attenuation force control value and the pitch attenuation force control value, attenuation force of a plurality of attenuation variable dampers 12a to 12d is controlled.SELECTED DRAWING: Figure 2
