Abstract
A suspension system for use on a motor vehicle includes a suspension having a leaf spring as a resilient member, and a plurality of strain gauges mounted on the leaf spring in suitable locations thereon. The value of a strain of the leaf spring in a particular position where one of the strain gauges is disposed is estimated on the basis of the measured value of a strain which is detected by another strain gauge. The difference between the estimated strain value and the value of a strain detected by the strain gauge in the particular position is then calculated. A deteriorated condition of the leaf spring can now be determined according to the calculated difference which is checked according to a preset reference or criterion.
