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.
