Abstract:
1. A method of controlling a vehicle roll control system comprising the steps of: (a) monitoring the position of a steering mechanism of a vehicle; (b) determining a rate of change of the position of the steering mechanism; (c) comparing the rate of change of the position of the steering mechanism to a first steering threshold value; (d) monitoring the lateral acceleration of a vehicle; (e) comparing the lateral acceleration to a first acceleration limit value; (f) monitoring a vehicle stability index; and (g) controlling a vehicle roll control system having front and rear actuators based at least in part upon the comparisons of the rate of change to the first steering threshold value and the lateral acceleration to the first acceleration limit value, wherein the front and rear actuators are controlled independently of each other based upon a state of understeer/oversteer of the vehicle stability index.
