1. A method for estimating weight-related parameter values of a vehicle, the method comprising:
receiving, from a sensor system of the vehicle, 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;
estimating, with a processor operably coupled to the sensor system and while the vehicle is stationary, one or more weight-related parameter values using a suspension model and the static sensor data;
determining, with the processor, degradation of the suspension system over time using a suspension sag estimation model and the dynamic sensor data;
updating, with the processor, the suspension model to accommodate for the degradation of the suspension system; and
displaying the one or more weight-related parameter values on a display device of the vehicle.
