1. A hitch assist system comprising:
- a detection system for determining a vehicle heading and a trailer heading;
a user-input device for accepting a specified angle of a vehicle heading relative a trailer heading; and
a controller coupled to the detection system for generating a path in response to the inputted specified angle along which the vehicle is autonomously maneuvered toward a trailer, the path ending at a final position based on the specified angle.

Abstract
A hitch assist system and method are provided herein. A detection system determines a vehicle heading and a trailer heading. A controller is coupled to the detection system for generating a path along which the vehicle is autonomously maneuvered toward a trailer. The path ends at a final position in which the vehicle and trailer headings are related by a specified angle therebetween.

12. A hitch assist system comprising:
-
a user-input device configured to receive user an inputted specified angle from a plurality of potential angles between a vehicle heading and a trailer heading after detecting a trailer; and a controller configured to generate a path in response to receiving the specified angle along which the vehicle is autonomously maneuvered and ending at a final position in which the vehicle and trailer headings are relatively positioned at the specified angle and instruct a user to input a different specified angle if the path is insufficient to avoid collision with an object. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A hitch assist method comprising the steps of:
-
providing a user-input device for inputting a first specified angle between a vehicle heading and a trailer heading to a controller; setting an allowable deviation range for the specified angle via the user-input device after inputting the first specified angle; and using the controller to generate a path in response to the inputted first specified angle and commands for autonomously maneuvering the vehicle along the path, the path ending at a final position in which the vehicle and trailer headings are related by the first specified angle or another angle encompassed by the allowable deviation range; and instructing input of a second specified angle if an object is disposed along the generated path.
