Abstract:
A suspension control apparatus selectively performs at least one of: compression-stroke control performed when a wheel load is increased, for setting a damping-force characteristic of at least one of damping-force variable dampers, which is provided on a side of at least one wheel whose wheel load is to be increased among a plurality of wheels, to a hard side in an early stage of a compression stroke and switching the damping-force characteristic to a soft side in a latter stage of the compression stroke; extension-stroke control performed when the wheel load is increased, for setting the damping-force characteristic to the soft side in an early stage of an extension stroke and switching the damping-force characteristic to the hard side in a latter stage of the extension stroke; compression-stroke control performed when the wheel load is reduced, for setting the damping-force characteristic of at least one of the damping-force variable dampers, which is provided on a side of at least one wheel whose wheel load is to be reduced, to the soft side in the early stage of the compression stroke and switching the damping-force characteristic to the hard side in the latter stage of the compression stroke; and extension-stroke control performed when the wheel load is reduced, for setting the damping-force characteristic to the hard side in the early stage of the extension stroke and switching the damping-force characteristic to the soft side in the latter stage of the extension stroke.
