Abstract
A method for vehicle stabilization includes, in response to a determination that a fault occurred in a rear steering mechanism, identifying a fault type associated with the fault. The method also includes determining whether a position of a rack of the rear steering mechanism is controllable based on the fault type. The method also includes, in response to a determination that the position of the rack is controllable, selectively positioning the rack to a center position and holding, using a motor control system of the rear steering mechanism, the rack in the center position. The method also includes, in response to a determination that the position of the rack is not controllable, holding, using the motor control system of the rear steering mechanism, the rack in a current position.
