Abstract: A towing configuration of a vehicle coupled to a trailer may be evaluated by rolling a tire of the coupled vehicle and trailer over a compressible region of a pressure vessel filled with a hydraulic fluid. A peak pressure of the hydraulic fluid as the tire rolls over the compressible region of the pressure vessel may be determined. The tire load may be determined based upon the peak pressure. Based at least in part on the tire load, a determination may be made whether the towing configuration satisfies a predetermined set of criteria.

Abstract: A method for dampening trailer sway, includes: receiving, by a controller of a vehicle system that is coupled to a trailer, a vehicle speed signal of the vehicle system, wherein the vehicle speed signal is indicative of a vehicle speed of the vehicle system; determining a friction force to be applied to the trailer by an actuator using the vehicle speed of the vehicle system and a graph that establishes a relationship between the friction force to be applied to the trailer and the vehicle speed; and adjusting, by the controller, the graph that establishes the relationship between the friction force and the vehicle speed using the decay rate of the plurality of oscillation amplitudes to create an updated graph.

Abstract: Methods and systems are provided for controlling deceleration of a vehicle towing a trailer. In an embodiment, a method includes: generating, by a processor, trailer brake command data to pulsate brakes of the trailer; in response to the generating the trailer brake command data, storing, in a data storage device of the vehicle, a first set of deceleration data; generating, by the processor, vehicle brake command data to pulsate brakes of the vehicle; in response to the generating the vehicle brake command data, storing, in the data storage device, a second set of deceleration data; determining, by the processor, a maximum vehicle brake torque threshold where a maximum trailer brake output occurs based on the first set of deceleration data and the second set of deceleration data; and controlling, by the processor, the brakes of the trailer based on the maximum vehicle brake torque threshold.

Abstract: In exemplary embodiments, methods and systems are provided that include: sensors configured to obtain sensor data for a vehicle having both friction braking and regenerative braking capabilities and coupled to a trailer, the sensor data including: friction braking data as to a vehicle friction braking force for the vehicle; and regenerative braking sensor data as to a vehicle regenerative braking force for the vehicle; and a processor coupled to the sensors and configured to at least facilitate controlling braking of the trailer by providing trailer braking force, via instructions provided by the processor, based on both the friction braking data and the regenerative braking sensor data, with a sensitivity toward the vehicle regenerative braking force such that the trailer braking force is affected differently by the vehicle regenerative braking force versus the vehicle friction braking force.
