Abstract: Methods and systems are provided for estimating weight-related parameter values of a vehicle. The system includes a sensor system, a display device, and a controller configured to, by a processor, receive, from the sensor system, static sensor data sensed while the vehicle is stationary and coupled to a trailer and dynamic sensor data while the vehicle is being driven and not coupled to the trailer, wherein the static sensor data includes a deflection value associated with a suspension system of the vehicle, estimate, while the vehicle is stationary, one or more weight-related parameter values using a suspension model and the static sensor data, determine degradation of the suspension system over time using a suspension sag estimation model and the dynamic sensor data, update the suspension model to accommodate for the degradation of the suspension system, and display the one or more weight-related parameter values on the visual display.

Abstract: A monocular camera system for a vehicle includes a front mono camera, a side mono camera, and one or more controllers in electronic communication with the front mono camera and the side mono camera. The one or more controllers execute instructions to determine an ideal lagged distance the vehicle travels between a current time step and a previous time step as two asynchronous camera frames are captured by the front mono camera and the side mono camera, determine a number of delayed frames captured by either the front mono camera or the side mono camera between the current time step and the previous time step based on the ideal lagged distance. The controllers determine a direction of travel of the vehicle that indicates which mono camera is selected to provide a previous camera frame captured at the previous time step.

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 determining a tire tread wear estimation of a tire includes receiving, by a controller, a direct tire tread wear measurement, when available, performing an indirect tire tread wear estimation, performing a data fusion of the indirect tire tread wear estimation with the direct tire tread wear measurement when available, estimating a percentage tire life remaining and a mileage to end of tire life, and estimating a refined tire tread wear calibration coefficient for performing future indirect tire tread wear estimations.
