Abstract
A control apparatus for a suspension apparatus, includes: a vehicle speed acquiring section which acquires a vehicle speed as a speed of a vehicle; an acquisition section which acquires a stroke velocity of the suspension apparatus; a contribution ratio determining section which determines a contribution ratio between a first parameter and a second parameter based on the vehicle speed, the first parameter serving for controlling a damping force in a first speed region of the vehicle, the second parameter serving for controlling the damping force in a second speed region which is a speed region higher in speed than the first speed region; a change amount restricting section which restricts a change amount of the contribution ratio; and a damping force controlling section which controls the damping force of the suspension apparatus based on the restricted contribution ratio and the stroke velocity.
