ABSTRACT:
A suspension controller for controlling the suspension characteristic of a vehicle having a suspension which supports a vehicle body on plural wheels, wherein the distance between the vehicle body and at least one of the wheels is measured and a corresponding signal indicating the height of the vehicle is produced. This height signal is compared against preset reference signals and the characteristic of the suspension is altered, e.g., the suspension is made harder or softer, in dependance on the comparison. Additionally, the preset reference signals themselves are changed depending upon the alteration in the characteristic of the suspension. Changing the reference signals eliminates influence of the change in the amplitude of vibration of the height of the vehicle as a result of altering of the suspension characterisitc, whereby exact detection of a change in the amplitude of the vibration due to irregularities of the road surface is enabled to prevent overcontrol and hunting.
