摘要：
A hydraulic shock absorber is provided a capability of quick response in such an extent that harder damping characteristics is provided during bounding stroke in each vibration cycle and softer damping characteristics is provided during rebounding stoke in each vibration cycle. The hydraulic shock absorber is controlled the damping characteristics for damping road shock by switching damping characteristics between harder damping characteristics and softer damping characteristics during normal mode operation. On the other hand, in attitude change suppression mode, suspension characteristics for suppressing vehicular body attitude change irrespective of the vibration mode.
