Abstract: Methods, systems, and apparatuses are provided for a vehicle tethered by a hitch to a trailer. The method includes generating sensor data from one or more sensors that are responsive to forces applied to the hitch by a vehicle mechanically coupled to the hitch; receiving sensor data to compute a direction for the guidance of the trailer; monitoring a set of parameters reflecting forces in a lateral and traverse direction derived from data generated by the sensors wherein the set of parameters include at least one parameter of a magnitude of force, and at least one parameter of the direction of force acting upon the hitch; and calculating at least a rate-of-change of the magnitude of force and direction over time to determine a trajectory for the trailer that enables the trailer to follow the lead vehicle without a tractive effort of the lead vehicle.
