Abstract

A method and system for operating a vehicle's trailer reverse assist system is disclosed, including receiving vehicle sensor system data from one or more sensors supported by the vehicle. Based upon the received vehicle sensor data, a trailer pitch angle and a trailer roll angle of a coupled trailer are estimated relative to the vehicle. Surface unevenness of a surface traversed by the vehicle and the trailer is estimated, based upon the estimated trailer pitch angle and the estimated trailer roll angle. One or more parameters of the trailer reverse assist system or of the tow vehicle are adjusted based upon the estimated road surface variance. The trailer reverse assist system of the tow vehicle is subsequently operated using the adjusted one or more parameters.
