Claim 10:
11. The method of claim 1:
further comprising, during the second time period, detecting an incline angle of the trailer;
wherein calculating the first target preload force opposite the first direction of motion of the trailer and proportional to the tractor-trailer angle comprises calculating the first target preload force opposite the first direction of motion of the trailer and inversely proportional to the incline angle of the trailer; and
further comprising, during a third time period:
detecting a third longitudinal force applied to the kingpin;
detecting a third lateral force applied to the kingpin;
detecting a decline angle and a third direction of motion of the trailer;
calculating a third total force applied to the kingpin by the hitch of the tow vehicle based on the third longitudinal force and the third lateral force;
calculating a third target preload force opposite the third direction of motion and proportional to the decline angle of the trailer; and
in response to the third total force exceeding the third target preload force, triggering the motor to regeneratively brake a driven axle to slow motion of the trailer and to decrease a third difference between the third total force and the third target preload force.
