Abstract
A rear suspension controller for controlling the suspension characteristic of a vehicle having a suspension which supports a vehicle body on plural wheels, wherein the acceleration of the vertical movement of at least one of the front wheels is measured and a corresponding signal is produced for detecting sporadic irregularities on a road surface. This acceleration signal is compared against preset reference signals and the characteristic of the rear suspension is altered, e.g., the suspension is made harder or softer, in dependence on the comparison in order to keep the controllability and stability or to maintain a good ride comfort according to demand. Additionally, the preset reference signals themselves are changed depending upon the vehicle speed because the influence of the shock caused by the irregularities changes according to the vehicle speed.
