Abstract
Official abstract text for this publication.
A method for temperature compensating an air spring of an air spring suspension of a motor vehicle after engine shut-off. A desired trim height is obtained. At engine shut-off, the ambient temperature is measured and the temperature of air in the air spring determined. After a wait time (for loading/unloading), a start trim height is measured. A predicted trim height is determined for when the air in the air spring is at the ambient temperature. Finally, the volume of the air in the air spring is selectively adjusted so that when the air in the air spring arrives at the ambient temperature, the trim height will be about the desired trim height.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for temperature compensating an air spring of an air spring suspension of a motor vehicle after engine shut-off, comprising the steps of: obtaining a desired trim height; shutting off the engine; measuring ambient temperature; determining temperature of air in the air spring; measuring a start trim height at a predetermined time after the engine shut-off; determining after the engine shut-off, via a dedicated computer, a predicted tr…
