Suspension apparatus for changing characteristics of a vehicle suspension by controlling hydraulic cylinders

摘要

A suspension apparatus for vehicles capable of changing the characteristic of the suspension by controlling supply/release of fluid into/from hydraulic cylinders which are respectively provided between a vehicle body and-at least two wheels provided on the right and left side of the vehicle body. The suspension apparatus includes a pressure detection sensor for detecting a pressure in the hydraulic cylinders and an acceleration detection sensor for detecting a lateral acceleration signal of the vehicle body. A target pressure difference is set to control supply/release of the fluid into/from the right and left cylinders based on the detected pressure differences of the right and left cylinders. The target pressure difference is corrected based on the detected lateral acceleration, and a flow amount supplied into and drawn from control-objective cylinders of the hydraulic cylinders is controlled using signals detected so that a pressure difference within the right and left cylinders goes toward the corrected target pressure difference.
