Abstract: A steer-by-wire assembly for a steering system in a vehicle is described. The system includes a shaft rotatable in response to a steering input, a clutch that includes a brake member rotatable with the shaft and a reaction member, and an electromagnetic actuator that is selectively actuated to selectively provide a force to selectively engage the brake and reaction members. When the actuator is not actuated, the force between the brake and reaction members limits or prevents rotation of the brake member relative to the reaction member. And when the actuator is actuated, the force between the brake and reaction members is reduced or removed to permit rotation of the brake member relative to the reaction member.

Abstract: A steer-by-wire assembly for a steering system in a vehicle is disclosed. The assembly includes a first shaft rotatable in response to a steering input, a second shaft adapted to rotate in response to rotation of the first shaft, a first gear (with a sensed element) that rotates in response to rotation of the first shaft, a second gear (with a sensed element) that rotates in response to rotation of the second shaft, a first sensing element adapted to sense the element carried by the first gear and provide an output associated with an angular position of the first gear, and a second sensing element adapted to sense the element carried by the second gear and provide an output associated with an angular position of the second gear. When the second shaft rotates relative to the first shaft, the outputs provide position and torque data associated with the steering input.
