Abstract
A damping force characteristic variable type shock absorber which takes a mode of operation into a first mode, a second mode, a third mode, and a fourth mode is connected to a damping force characteristic basic mode switching block and a damping force characteristic special mode switching block. This first mode is such that when the vehicular vertical direction determined by the vehicular vertical behavior determinator is upward, an extension phase provides a relatively high damping force characteristic and a compression phase provides a relatively low damping force characteristic. The second mode is such that when the vehicular vertical direction determined by the vehicular vertical behavior determinator is downward, the extension phase provides a relatively low damping force characteristic and the compression phase provides a relatively highly damping force characteristic. The third mode is such that when the vehicular vertical behavior determinator is neither upward nor downward, both of extension and compression phases provide the relatively low damping force characteristics. The fourth mode is such that when a predetermined condition of a vehicular motion is satisfied, the dam…
