PURPOSE:To obtain a vehicle suspension device in which sufficient vibration damping is obtained even to the inclination of a car body by inertia moment, and comfortableness and operation stability are improved. CONSTITUTION:There are provided a dumping characteristic control means e having a basic control part d for controlling the damping characteristic of each shock absorber b based on a control signal obtained from sprung vertical speed, and a roll correction part f provided in the damping characteristic control means e and for controlling a correction rate obtained from the product of a difference in sprung vertical speed and sprung vertical speed based on a control signal added to the control signal obtained from the sprung vertical speed, when the direction of the sprung vertical speed and the direction of a difference in sprung vertical speed between the right car body and the left car body are the same in direction. There is provided a pitch correction control part g provided in the damping characteristic control means e and for controlling a correction rate obtained from the product at a difference in sprung vertical speed and sprung vertical speed based on a control signal added to the control signal obtained from the sprung vertical speed, when the direction of the sprung vertical speed and the direction of a difference in sprung vertical speed between the front car body and the rear car body are the same in direction. |
