Abstract

The effects of suspension properties, particularly roll steer and compliance steer, on vehicle stability in a cross wind are examined using measurements of the vehicle's roll angle and steer angles of the front and rear wheels when the vehicle is subjected to a lateral wind. Further consideration is made with a simulation model. The following main results are obtained: The roll angle and the cornering forces of the front and rear wheels exhibits a transient reversal of direction in a cross wind. Accompanying this vehicle behaviour, the roll steer and compliance steer of the rear wheels, in particular have substantially different effects on cross wind stability.
