    摘要: A vehicle vibration control apparatus in which springs (3A) and (3B) for supporting the vehicle body place in juxtaposition with cylinders (4A) and (4B) for damping the vertical vibrations and a cylinder (4C) for damping the lateral vibrations. The detection signal from the vibration acceleration detectors (5A), (5B) and (5C) are compensated for by compensator circuits (6A), (6B) and (6C), and further amplified by amplifiers (7A), (7B) and (7C) thereby to control the internal pressure of the cylinders (4A), (4B) and (4C) by servo valves (8A), (8B) and (8C). The compensator circuit is comprised in a such manner that the transfer function thereof takes the form of the product of an integration response element, first order lead response elements and first order lag response elements, and therefore the response characteristic of the vehicle body on the vibration acceleration has no peak over a wide range of frequencies.
