Vehicle steering system having a user experience based automated driving to manual driving transition system and method
First Claim
1. A steer by wire steering system for a vehicle, comprising:
- a steering wheel selectively coupled to a steering shaft, the steering wheel and steering shaft axially movable between a deployed position and a retracted position;
an advanced driver assist system configured to steer one or more steerable wheels of a vehicle that is in communication with the steering wheel and steering shaft, the advanced driver assist system configured to selectively control the steering of the one or more steerable wheels in an autonomous driving mode that does not require steering input of a vehicle operator and a manual driving mode that does require steering input of a vehicle operator;
a steering system controller in communication with the advanced driver assist system, the steering system controller programmed to, while the steering wheel is in the retracted position, move the steering wheel to the deployed position in an automatic and motorized manner and operatively couple the steering wheel to the steering shaft, in response to a vehicle operator request to deactivate a portion of the advanced driver assist system and transition from the autonomous driving mode to the manual driving mode; and
an input device for receiving the operator request, the input device comprising a force sensor in communication with the controller, the operator request comprising application of an axial force to the steering wheel.

Abstract
A steer by wire steering system includes a steering wheel selectively coupled to a steering shaft, the steering wheel and steering shaft axially movable between a deployed position and a retracted position; an advanced driver assist system configured to steer the steerable wheels of a vehicle that is in communication with the steering wheel and steering shaft, the ADAS configured to selectively control the steering of the steerable wheels in an autonomous driving mode and a manual driving mode; and a steering system controller in communication with the ADAS, the steering system controller programmed to, while the steering wheel is in the retracted position, move the steering wheel to the deployed position and operatively couple the steering wheel to the steering shaft, in response to a vehicle operator request to deactivate a portion of the ADAS and transition from the autonomous driving mode to the manual driving mode.

9. A selectively autonomously controllable vehicle comprising a steer by wire steering system, comprising:
-
a steering shaft axially movable between a deployed position and a retracted position; an advanced driver assist system configured to steer one or more steerable wheels of a vehicle that is in communication with the steering shaft, the advanced driver assist system configured to selectively control the steering of the one or more steerable wheels in an autonomous driving mode that does not require steering input of a vehicle operator and a manual driving mode that does require steering input of a vehicle operator; a steering system controller in communication with the advanced driver assist system, the steering system controller programmed to, while the steering shaft is in the retracted position, move the steering shaft in an automatic and motorized manner to the deployed position in response to a vehicle operator request to deactivate a portion of the advanced driver assist system and transition from the autonomous driving mode to the manual driving mode; and an input device for receiving the operator request, the input device comprising a force sensor coupled to the steering shaft and in communication with the controller.

11. A Steering Wheel Stow Assist System (SWSAS) for a steering system of a vehicle, comprising:
-
a steering wheel selectively coupled to a steering shaft, the steering wheel and steering shaft axially movable between a deployed position and a retracted position in an automatic and motorized manner; an advanced driver assist system configured to steer one or more steerable wheels of a vehicle that is in communication with the steering wheel and steering shaft, the advanced driver assist system configured to selectively control the steering of the one or more steerable wheels in an autonomous driving mode that does not require steering input of a vehicle operator and a manual driving mode that does require steering input of a vehicle operator; an axial force sensor operatively coupled to the steering shaft; and a steering system controller in communication with the advanced driver assist system and the axial force sensor, the steering system controller programmed to, while the steering wheel is in the retracted position, move the steering wheel to the deployed position and operatively couple the steering wheel to the steering shaft, in response to a vehicle operator request to deactivate a portion of the advanced driver assist system and transition from the autonomous driving mode to the manual driving mode. - View Dependent Claims (12, 13)
