Coordination Strategies for Combined Steering and Individual Wheel Braking Actuated Vehicle Yaw Stability Control

Abstract

The road vehicle yaw stability controller is an important element of the vehicle active safety system. Yaw stability control systems operate within the panic reaction time of the driver and generate corrective yaw moments through either steering or individual wheel braking. While yaw stability controllers based on steering or individual wheel braking have been formulated quite frequently, controllers that make coordinated use of both methods of actuation are not so common. This paper addresses the combined and coordinated use of both methods of actuation in a model regulator based yaw stability controller for improved performance
