Claim 0:
1. A system for vehicle stabilization, the system comprising:
a processor; and
a memory that includes instructions that, when executed by the processor, cause the processor to:
in response to a determination that a fault occurred in a rear steering mechanism, identify a fault type associated with the fault;
determine whether a position of a rack of the rear steering mechanism is controllable based on the fault type;
in response to a determination that the position of the rack is controllable:
selectively position the rack to a center position; and
hold, using a motor control system of the rear steering mechanism, the rack in the center position using a rack position controller and a zero target position command; and

in response to a determination that the position of the rack is not controllable, disable the rack position controller by shorting, via an inverter, one or more phases of a motor associated with the rear steering mechanism to ground to hold, using the motor control system of the rear steering mechanism, the rack in a current position, wherein the current position includes a position of the rack associated with the fault and wherein holding the rack in the current position incudes not moving the rack out of the current position.
