The present disclosure provides a "steering column retraction actuator". A steering wheel actuator for a steering-by-wire system of a vehicle may include: a column for operably coupling a steering wheel to other components of the steering-by-wire system; and a feedback actuator operably coupled to the column to provide haptic feedback to the operator in response to movement of the steering wheel. The column may include a lower column portion and an upper column portion that are movable relative to each other to alternately retract the steering wheel away from an operator seated in the vehicle or extend the steering wheel toward the operator. The column may also include a frictional engagement assembly and a time-specific release actuator. The friction engagement assembly may be engaged to secure the lower column portion at a selected distance from the operator relative to the upper column portion, and disengaged to enable movement of the upper column portion relative to the lower column portion. The time-specific release actuator may be actuated by an electrical trigger signal to disengage the lower column portion and the upper column portion at a selected time after a trigger event.

    本公开提供了“转向柱缩回启动器”。一种用于车辆的线控转向系统的方向盘致动器可以包括:用于将方向盘可操作地联接到所述线控转向系统的其他部件的柱;以及反馈致动器,所述反馈致动器可操作地联接到所述柱以响应于所述方向盘的移动而向所述操作员提供触觉反馈。所述柱可以包括下柱部分和上柱部分,所述下柱部分和所述上柱部分可相对于彼此移动以交替地使所述方向盘远离坐在所述车辆中的操作员缩回或使所述方向盘朝向所述操作员伸展。所述柱还可以包括摩擦接合总成和时间特定的释放启动器。所述摩擦接合总成可以被接合以相对于所述上柱部分在距所述操作员的选定距离处固定所述下柱部分,并且脱离接合以使得所述上柱部分能够相对于所述下柱部分移动。所述时间特定的释放启动器可以由电触发信号致动,以使所述下柱部分和所述上柱部分在触发事件之后的选定时间脱离接合。
