Abstract
A trailer reverse assist system includes a coupler angle detection sensor to detect a zero degree angle of the trailer relative to the vehicle. A drift controller receives signals from vehicle dynamics sensors. The drift controller is electrically connected with a trailer reverse assist module. When the vehicle is backing up the trailer on the intended straight line implied path and since the coupler angle sensor, detecting the zero degree angle, is not perfectly calibrated, based in the signals from the vehicle dynamics sensors, the drift controller 1) estimates a distance that the trailer has drifted from the straight line desired path and 2) in a closed-loop feedback manner, provides a drift correction signal to the trailer reverse assist module for modifying the value of the zero degree angle and thus cause adjustment of the steering system to realign the trailer towards the straight line implied path without manual steering intervention.
