  • Patent number: 5948027
    Abstract: A method of enhancing vehicle stability and response in a vehicle having an active roll control system with front and rear suspensions each including an anti-roll bar, and the control system including a hydraulic system for providing an anti-roll moment which acts on the vehicle by means of hydraulic cylinders connected to the anti-roll bars, includes the following steps: a) determining the vehicle speed; b) determining the steering wheel angle; c) calculating the desired vehicle yaw rate based upon the determined speed and steering wheel angle; d) sensing the actual yaw rate; e) comparing the desired yaw rate to the actual yaw rate; f) increasing the percentage of the anti-roll moment provided to the rear anti-roll bar if the actual yaw rate is less than the desired yaw rate, thereby decreasing understeer, increasing yaw rate, and enhancing vehicle response; and g) increasing the percentage of the anti-roll moment provided to the front anti-roll bar if the actual yaw rate is greater than the desired yaw rate
