    Abstract: A method for reversing an articulated vehicle comprising a tractor and one or more towed vehicle units, the method comprising arranging an electrified trailer (e-trailer) comprising one or more electric machines (EMs) and a steering function as a rearmost towed vehicle unit of the articulated vehicle, obtaining a reversal command indicative of a desired reversal maneuver by the articulated vehicle, configuring the e-trailer in a reverse towing mode of operation, wherein the e-trailer uses the one or more EMs and the steering function to reverse according to the reversal command while towing the tractor and any further trailer units of the articulated vehicle, configuring the tractor and the further trailer units of the articulated vehicle in a passive towed mode of operation, wherein the tractor and the further trailer units are towed by the e-trailer, and reversing the articulated vehicle by issuing the reversal command to the e-trailer.

    Abstract: A multi-vehicle control system (MVCS) for dynamic stability and control of a multi-vehicle system having a lead vehicle and a trailer vehicle each with independent propulsion and control. The MVCS includes a controller in signal communication with the lead vehicle and a trailer vehicle advanced driver assistance system (ADAS) or autonomous driving system via a controller area network (CAN) bus. The controller is configured to (i) receive throttle, brake, and steering signals respectively from a throttle-by-wire system, a brake-by-wire system, and a steer-by-wire system of the trailer vehicle ADAS or autonomous driving system, (ii) receive lead vehicle control inputs from the lead vehicle, and (iii) modify a throttle, a steering, and a braking of the trailer vehicle, based on the received lead vehicle control inputs, to dynamically stabilize the multi-vehicle system such that the trailer vehicle does not induce forces that accelerate or slow the lead vehicle.

    Abstract: A human machine interface (HMI) system for a multi-vehicle system having a lead vehicle and a trailer vehicle with independent propulsion and control includes a display disposed in the lead vehicle, a lead vehicle sensor suite, a trailer vehicle sensor suite, and a controller configured to generate a trailer reverse screen on the display. The trailer reverse screen includes (i) a trailer rear view showing a view from one or more cameras located on a rear of the trailer vehicle, (ii) a multi-vehicle system top view showing a view from above the multi-vehicle system based on signals from one or more cameras located on the multi-vehicle system, and (iii) a lead vehicle backup camera view from a lead vehicle backup camera, to thereby provide a driver of the lead vehicle with an intuitive perspective for reversing the trailer vehicle without aid from another person outside of the lead vehicle.

    Abstract: A method S100 can include: determining a set of inputs S110; determining a vehicle state estimate S120; determining a vehicle command based on the vehicle state estimate S130; and optionally controlling the vehicle based on the vehicle command S140. However, the method S100 can additionally or alternatively include any other suitable elements. The method S100 functions to facilitate vehicle reversal and/or tractable vehicle control (e.g., during reversal). Additionally or alternatively, the method can function to reduce and/or eliminate unrecoverable vehicle state incidence during vehicle reversal (a.k.a., vehicle backing). Additionally or alternatively, the method can function to autonomously augment and/or assist vehicle control (e.g., during vehicle reversal).

    Abstract: Systems, apparatus, and methods for steering one or more wheels of a flat-towed vehicle moving in reverse. A system may include a power steering mechanism configured to steer the one or more wheels. The system may further include a connector configured to carry one or more signals from a towing vehicle to the flat-towed vehicle. The system may further include an electronic control unit (ECU) coupled to the power steering mechanism and the connector. The ECU may receive a signal that one or more reverse lights of the towing vehicle are lit or on. The ECU may be configured to actuate the power steering mechanism to steer the one or more wheels to a straight position upon receiving the signal.
