    Abstract: An axially adjustable steering column assembly includes an upper jacket. And a lower jacket. The steering column assembly further includes a column mounting bracket, wherein the lower jacket is operatively coupled to the column mounting bracket and translates relative to the column mounting bracket, wherein the column mounting bracket defines a first set of tapered rail slots, each of the first set of tapered rail slots disposed on opposite sides of the column mounting bracket and extending longitudinally along the column mounting bracket, wherein the lower jacket defines a second set of tapered rail slots, each of the second set of tapered rail slots disposed on opposite sides of the lower jacket and extending longitudinally along the lower jacket. The steering column assembly yet further includes a first pair of sliding wedge bushings disposed within the first set of tapered rail slots.

    Abstract: A method of controlling a dual wound synchronous machine (DWSM) includes: determining virtual current commands based on a current command associated with each of two winding sets of the DWSM; determining virtual half-motor currents by applying a mathematical transformation on measured output currents; determining half-motor difference currents based on differences between the corresponding virtual current command and the virtual half-motor current; calculating forward path voltage commands based on the corresponding difference currents and using first and second gain factors; determining feedback voltage commands by applying third and fourth gain factors to the virtual half-motor currents; determining virtual final voltage commands based on the corresponding forward path and feedback voltage commands; determining final voltage commands by applying a second mathematical transformation to the virtual final voltage commands; commanding, based on the final voltage commands, inverters to apply corresponding voltages to the two winding sets and thereby generating the output currents.

    Abstract: A method for providing reverse directional polarity steering in a vehicle includes, in response to receiving a reverse position polarity steering mode signal indicating selection of a reverse position polarity steering mode: determining a selected gear of a transmission of the vehicle; determining a vehicle speed; and, in response to a determination that the selected gear includes a reverse gear and the vehicle speed is within a range of a predetermined vehicle speed, selectively controlling at least one roadwheel actuator of the vehicle in a direction opposite to a direction indicated by a handwheel actuator associated with a handwheel of the vehicle.

    Abstract: An adjustment actuator assembly for a vehicle steering system includes a leadscrew having a threaded outer surface and at least one pocket recessed radially inwardly from an outer diameter of the threaded outer surface. The adjustment actuator assembly also includes a nut having a threaded inner surface engaged with the threaded outer surface of the leadscrew, the nut axially moveable along the leadscrew during rotation of the leadscrew. The adjustment actuator assembly further includes a travel stop limiter operatively coupled to the nut, the travel stop limiter having a leg extending through an opening of the nut and spring biased into contact with the threaded outer surface of the leadscrew and moveable into the pocket of the leadscrew to limit axial translation of the nut.
