This paper demonstrates the ride comfort performance enhancement of the new road vehicle series active variable-geometry suspension (SAVGS) concept using a Fuzzy-logic control technique. In this study utilizes a nonlinear full-car model, for a Grand Tourer (GT) car, that represents accurately the dynamics and geometry of a high-performance car with the new double-wishbone active suspension concept. The proposed controller is installed on the nonlinear full-car model, and its performance is examined for the parameters, e.g. center of mass (CM) height, roll, and pitch angles. The height of the CM would stay at the desired amount (0.35m) at every bump or hole there are on the path of the vehicle. The controller has four output for each wheel suspension systems. The proposed system improves the CM height fluctuations by about 30%.
