Abstract
A trailer reverse assist (TRA) system for a tow vehicle aids in reversing an attached trailer. The TRA system includes a processor circuit; at least one camera to obtain images of the trailer; and vehicle dynamic sensors to obtain vehicle dynamics data from the vehicle. The processor circuit, while the TRA system is in a standby, non-active state and while the vehicle is in Drive and traveling forward at a speed above a threshold speed: learns parameters and/or image features of an attached trailer based on data from the at least one camera and the vehicle dynamic sensors; causes the learned parameters and/or image features of the attached trailer to be stored in a database; and informs the driver via the infotainment system that the TRA system can be activated.
