Control modes for a trailer backup assist system
First Claim
1. A method for reversing a trailer with a vehicle, comprising:
- placing the vehicle and trailer in a static orientation;
providing a mode selection device for selecting between a trailer straight routine and a vehicle straight routine;
based on the selection, generating a reference path in line with longitudinal direction of the trailer or vehicle in the static orientation; and
autonomously steering the vehicle to guide the trailer on the reference path.

Abstract
A trailer backup assist system, according to one embodiment, provides a sensor that senses a hitch angle between a trailer and a vehicle. The trailer backup assist system also provides a selection device for selecting a longitudinal direction of the trailer or the vehicle in a static orientation. Further, the trailer backup assist system provides a controller that generates a steering command to the vehicle when reversing based on the hitch angle to guide the trailer in the selected longitudinal direction. The controller determines a kinematic relationship of the trailer and the vehicle based on a length of the trailer and a wheelbase of the vehicle, whereby the steering command is generated based on the kinematic relationship.
