Claim 4:
5. The method of claim 1:
further comprising, during the first time period, detecting a first duration of the trailer exhibiting the first speed;
wherein calculating the first target preload force opposite the direction of motion of the tow vehicle and proportional to the tractor-trailer angle comprises calculating the first target preload force opposite the direction of motion of the tow vehicle and inversely proportional to the first duration; and
further comprising, during a third time period:
detecting a third speed corresponding to the first speed and a third direction of motion of the trailer;
detecting a second duration of the trailer exhibiting the first speed;
detecting a third total force applied to the kingpin by the hitch;
in response to the second duration exceeding the first duration, calculating a third target preload force, less than the first target preload force, opposite the direction of motion and inversely proportional to the second duration; and
in response to the third total force falling below the third target preload force, triggering the motor to reduce torque output in the third direction of motion to decrease a third difference between the third total force and the third target preload force.
