    Abstract: Methods and systems are provided for a vehicle towing a trailer. In an exemplary embodiment, one or more sensors onboard a vehicle are configured to provide sensor data, and a processor onboard the vehicle is configured to at least facilitate: monitoring a trailer sway of the trailer using the sensor data, based on one or more parameters of the sensor data representing the trailer sway and application of a band-pass filter to the one or more parameters; and mitigating the trailer sway, via instructions provided by the processor to one or more braking systems of the vehicle, the trailer, or both, when it is determined that the trailer sway of the trailer is sufficient to warrant mitigation based on the one or more parameters of the sensor data representing the trailer sway and the application of the band-pass filter to the one or more parameters.

    Abstract: A vibration monitoring system includes a plurality of encoders and an analyzer. The encoders are configured to generate multiple pulse train signals for multiple wheels. Each encoder is coupled to a respective one of the multiple wheels and generates a single one of the pulse train signals. The analyzer is coupled to the encoders and is configured to generate multiple pulse per revolution signals and multiple angular velocity signals for the wheels in response to the pulse train signals. Each pulse per revolution signal conveys a single pulse per rotation of the respective wheel. The analyzer is further configured to generate an input phasor array representative of the pulse per revolution signals, generate a response phasor array in response to the angular velocity signals for the wheels, and generate a report that identifies at least one vibrating wheel in response to the input phasor array and the response phasor array.

    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.
