End of travel feature for steer by wire vehicle
First Claim
1. A system for providing an end of travel feedback from a road wheel to a driver of a vehicle, the vehicle including a steer by wire system, the system comprising:
- a steering wheel configured to control the steer by wire system;
a steering shaft coupled to the steering wheel;
a clutch adapted to couple the steering shaft with the road wheel based on an end of travel condition; and
a controller adapted to sense when the road wheel has reached an end of travel position based on the controller or a sensor and to engage the clutch in response thereto.

Abstract
The present invention provides a system for generating an end of travel feedback to the driver of a vehicle where the vehicle includes a steer by wire system. The system includes a steering wheel, a steering shaft, a motor, and a clutch. The steering wheel is configured to control the steer by wire system. The steering shaft is coupled to the steering wheel and rotates in conjunction with the steering wheel. To provide road feel resistance to the driver, the motor is coupled to the steering shaft. Further, the clutch is configured to mechanically couple the steering shaft to the road wheel to provide mechanical resistance when the road wheel is at an end of travel position.

14. A method for providing an end of travel feedback to a driver of a vehicle, the vehicle including a steer by wire system and a road wheel, the method comprising the steps of:
-
controlling the steer by wire system with a steering mechanism;
sensing that a road wheel angle of the road wheel is at an end of travel position; andcoupling the steering mechanism to the road wheel mechanically based on the step of sensing that the road wheel angle is at an end of travel position. - View Dependent Claims (15, 16, 17, 18, 19, 25)

20. A method for providing an end of travel feedback to a driver of a vehicle, the vehicle including a steer by wire system and a road wheel, the method comprising the steps of:
-
controlling the steer by wire system with a steering mechanism; sensing a road wheel angle of the road wheel is at an end of travel position; coupling the steering mechanism to the road wheel mechanically; and decoupling the steering mechanism from the road wheel when the steering wheel is manipulated to rotate the wheel away from the end of travel position. - View Dependent Claims (21, 22, 23)
