Abstract
A trailer reversing assist system for controlling reversing operations of a vehicle and trailer connected to the vehicle includes a module that detects an angle of the trailer relative to the vehicle, and outputs a trailer angle signal corresponding to the detected angle. The system also includes a human machine interface (HMI) device that provides an output signal based upon an input of the user, where the generated output signal includes information regarding magnitude and direction of a desired change to the angle. The system calculates a trailer trajectory that positions the trailer at a target location or calculates a trailer trajectory correction, wherein the calculation is performed using the output signal as corresponding to a change relative to the detected angle, and the detected angle corresponds to the trailer angle signal generated at the time of operation of the HMI device by the user.
