PROBLEM TO BE SOLVED: To provide a suspension control device capable of securing an excellent dither effect regardless of a product error. SOLUTION: A dither adjusting acceleration signal corresponding to dither frequency, that is, the vibration component of a vehicle caused by the application of a dither current, is extracted from an acceleration signal detected by an acceleration sensor 7 (step S10). Dither amplitude is determined on the basis of the adjusting acceleration signal (steps S11-S14 and steps S16-S19), and the dither amplitude is used for driving a proportional solenoid valve (actuator). The dither amplitude can be appropriately adjusted with respect to an object product even with a product error, that is, the product error can be absorbed, and in its turn, an excellent dither effect can be ensured for every product regardless of the product error. The generation of sound and vibration, and worsening of responsiveness and hysteresis can be suppressed to provide an excellent riding comfort. |
