1. A method for operating a trailer reverse assist system of a tow vehicle coupled to a trailer, the trailer reverse assist system including data processing hardware, the method comprising:
receiving, at the data processing hardware, vehicle sensor system data from one or more sensors supported by the vehicle;
estimating, based upon the received vehicle sensor data, a trailer pitch angle and a trailer roll angle, relative to the tow vehicle;
estimating, at the data processing hardware, surface unevenness of a surface traversed by the tow vehicle and the trailer, based upon the estimated trailer pitch angle and the estimated trailer roll angle;
adjusting, at the data processing hardware, one or more parameters of the trailer reverse assist system or of the tow vehicle based upon the estimated surface unevenness;
operating, by the data processing hardware, the trailer reverse assist system of the tow vehicle using the adjusted one or more parameters; and,
determining, at the data processing hardware, trailer pitch angle variance based upon the estimated trailer pitch angle, and determining, at the data processing hardware, trailer roll angle variance based upon the estimated trailer roll angle, wherein estimating the surface unevenness is based upon the trailer pitch angle variance and the trailer roll angle variance.
