    Abstract: A method for implementing directional control of a motor vehicle is disclosed. In an exemplary embodiment, the method includes determining whether a failure of a primary steering system of the motor vehicle exists. If a failure of the primary steering system exists, then a yaw moment is created on the vehicle by causing a differential longitudinal force to be applied with respect to a first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle, thereby causing the vehicle to turn in a commanded direction.

    Abstract: Disclosed is a method for assisting the parking of a vehicle. The method includes determining a vehicle position relative to an obstacle. When the relative position meets a first set of criteria, a first torque pulse is delivered to the steering wheel in the first direction to cue an operator of the vehicle to turn the steering wheel in the first direction. When the relative position meets a second set of criteria, a second torque pulse is delivered to the steering wheel in the second direction, opposite to the first direction to cue the operator to turn the steering wheel in the second direction. A system for assisting the parking of a vehicle is also disclosed.
