PROBLEM TO BE SOLVED: To reduce energy consumption by a simple structure in a suspension control device. SOLUTION: Left and right suspension units 2 of the vehicle are connected to each other through a dual-direction hydraulic pump 3. A motor 4 for driving the dual-direction hydraulic pump 3 is controlled by a controller 6 based on the vehicle state detected by a lateral acceleration sensor 11, a steering angle sensor 12 and a vehicle height sensor 17, and rolling of the vehicle body at turning is suppressed by transferring an oil liquid between the left and right suspension units 2. At this time, in the controller 6, high-pass filter processing is performed relative to a control signal based on detection of the vehicle height sensor 17. Thereby, the control signal of low frequency can be cut relative to steady inclination of the vehicle body due to variation of loading load caused by getting in/out of an occupant, unnecessary attitude control is prevented from being performed and energy consumption can be reduced.
