TORQUE FEEDBACK SYSTEM FOR A STEER-BY-WIRE VEHICLE, VEHICLE HAVING STEERING COLUMN, AND METHOD OF PROVIDING FEEDBACK IN VEHICLE

摘要

A torque feedback system for a vehicle includes a steering shaft having a longitudinal axis, a jacket surrounding the shaft, the shaft rotatable with respect to the jacket, and at least one mechanical energy storing element arranged to provide torque feedback when the steering shaft is rotated. The at least one mechanical energy storing element includes a first mechanical energy storing element having a first end engageable with the jacket and a second end engageable with the shaft, and a second mechanical energy storing element having a first end engageable with the jacket and a second end engageable with the shaft. The first mechanical energy storing element provides resistance to rotation of the shaft in a first rotational direction, and the second mechanical energy storing element provides resistance to rotation of the shaft in a second rotational direction.
