Abstract: It is well understood that the driver's steering input strongly affects lateral vehicle dynamics, and excessive steering command may result in unstable vehicle motion. In a certain driving condition, it is possible for a skilled driver to prevent vehicle rollover with better perceptive capability of judging conditions and responding faster with smooth compensatory actions. This paper investigates the possibility of using active steering and wheel torque control to assist drivers in avoiding vehicle rollovers in emergency situations. The effectiveness of steering control alone and the combination of steering/wheel torque control in recovery from an unstable roll condition were demonstrated through simulation of both low and high vehicle speeds.
