Classification: CPC G  B | IPC B  G

Claim 11:
12. The method of claim 11:
wherein detecting the direction of motion of the tow vehicle comprises detecting the direction of motion of the trailer in a forward direction;
wherein calculating the first target preload force opposite the first direction of motion and proportional to the tractor-trailer angle comprises calculating the first target preload force, in a reverse direction, opposite the forward direction and inversely proportional to the incline angle;
wherein triggering the motor to reduce torque output in the first direction of motion comprises triggering the motor to reduce torque output in the forward direction to decrease the first difference between the first total force and the first target preload force;
wherein triggering the motor to increase torque output in the second direction of motion to decrease the second difference comprises triggering the motor to increase torque output in the forward direction to decrease the second difference between the second total force and the second target preload force;
wherein calculating the third target preload force opposite the third direction of motion comprises calculating the third target preload force in a reverse direction, opposite the forward direction, and proportional to the decline angle of the trailer; and
wherein triggering the motor to regeneratively brake the driven axle to increase torque output to slow motion of the trailer comprises triggering the motor to regeneratively brake the driven axle to increase torque output in the reverse direction to decrease the third difference between the third actual force and the third target preload force.
