    摘要： A method for determining a trailer detection parameter of a trailer including receiving an image from at least one camera at a controller. The at least one camera defines a field of view including at least a portion of a vehicle trailer. The method determines a trailer angle of the vehicle trailer relative to a tractor, identifies at least one feature in an image of the trailer, determines a two-dimensional distance from the at least one feature to a predefined position on the image, and converts the two-dimensional distance to a three-dimensional distance based at least in part on the determined angle. The three-dimensional distance is a trailer detection parameter of the trailer.

    摘要： A method for reversing an articulated vehicle (100, 300, 700, 800) comprising a tractor (110) and one or more towed vehicle units (120, 130, 140, 150), the method comprising arranging (S1) an electrified trailer, e-trailer, (200) comprising one or more electric machines, EM, (410) and a steering function (420) as a rearmost towed vehicle unit (130) of the articulated vehicle,
    obtaining (S2) a reversal command indicative of a desired reversal maneuver by the articulated vehicle (100, 300, 700, 800),
    configuring (S3) the e-trailer in a reverse towing mode of operation, in which mode the e-trailer is arranged to use the one or more EMs and the steering function to reverse according to the reversal command while towing the tractor (110) and any further trailer units (120, 140, 150) of the articulated vehicle,
    configuring (S4) the tractor (110) and the further trailer units (120, 140, 150) of the articulated vehicle in a passive towed mode of operation, in which mode the tractor (110) and the further trailer units (120, 140, 150) are arranged to be towed by the e-trailer, and reversing (S5) the articulated vehicle (100, 300, 700, 800) by issuing the reversal command to the e-trailer.
