1. An autonomous steering system for a vehicle, comprising:
- a park assist system configured to generate a first steering angle command across a communication network of the vehicle;
a trailer backup assist system configured to generate a second steering angle command across the communication network of the vehicle; and
a steering angle controller configured to receive the first and second steering angle commands and generate a third steering angle command for controlling a steered wheel of the vehicle based on steering column torque conditions of the vehicle being acceptable for the park assist and trailer backup assist systems, respectively.

Abstract
An autonomous steering system for a vehicle includes a park assist steering module configured to generate a first steering angle command across a communication network of the vehicle. A backup assist steering module is also configured to generate a second steering angle command across the communication network of the vehicle. A steering angle controller is configured to receive the first and second steering angle commands and generate a third steering angle command for controlling a steered wheel of the vehicle based on acceptable steering column torque conditions for the respective steering module.

8. A method for steering angle control of a vehicle, comprising:
-
generating a first steering angle command with one of park assist system and a trailer backup assist system, each of which has an open state arbitration condition; and providing a steering angle controller configured to generate a second steering angle command for steering the vehicle based on the first steering angle command and acceptable steering column torque conditions for the one of the park assist system and the trailer backup assist system. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An autonomous steering system for a vehicle, comprising:
-
a park assist system and a trailer backup assist system, each configured to generate a steering angle command when an open state condition is present for independently steering the vehicle; and a steering angle controller configured to control a steered wheel of the vehicle based on the generated steering angle commands when a sensed steering torque of the vehicle is less than a threshold torque. - View Dependent Claims (16, 17, 18, 19, 20)
