First Claim
Patent Images
1. A suspension control system for an automotive vehicle comprising:
- means for adjusting suspension characteristics of a suspension system disposed between a vehicle body and a suspension member on which a vehicular wheel is supported;
means for monitoring lateral acceleration exerted on the vehicular body and for producing a lateral acceleration indicative signal;
means for deriving a variation rate of lateral acceleration on the basis of said lateral acceleration indicative signal;
means for detecting a vibration mode of the vehicular body on the basis of the variation rate of lateral acceleration, for producing a suspension control signal representative of one of a plurality of suspension characteristics on the basis of the detected vibration mode of the vehicular body, for controlling said suspension characteristics adjusting means.

Abstract
A suspension control system monitors a lateral acceleration exerted on a vehicular body. Based on the lateral acceleration, discrimination of mode of vibration of a vehicular body is performed by deriving variation rate of magnitude of lateral acceleration. The variation rate of lateral acceleration is then compared with a reference value so that suspension characteristics can be controlled on the basis of the variation rate of the lateral acceleration.
