Abstract
[Object] The present invention provides a suspension control apparatus that allows miniaturization of a solenoid valve. [Solution] When a controller is started up by a power source controller (a power source unit), the controller switches a control current from 0 ampere to a maximum current value Iat the same time as the startup. After that, the control shifts to normal control. As a result, even if a hysteresis of a damping force characteristic is large relative to the control current, it is possible to promptly move a solenoid valve to a position to be used in the normal control.
