Abstract
An electronically controlled fluid suspension system detects an average longitudinal or lateral acceleration within a predetermined period, computes an acceleration difference between a maximum average acceleration and a minimum average acceleration. Based on the acceleration difference, an estimated longitudinal or lateral acceleration is computed. In response to the estimated longitudinal or lateral acceleration, computed are a height-raising quantity of a lowered portion of a vehicle and a height-lowering quantity of a raised portion thereof. The supply and release of a fluid to and from fluid springs is rapidly controlled so that the height-raising quantity of the lowered portion of the vehicle is less than the height-lowering quantity of the raised portion thereof. The electronically controlled fluid suspension system, thus, prevents the vehicle from inclining due to changes in driving status, and enhances a road-adherence ability on an uneven road as well as a steering stability.
