The present disclosure related to a travel stop assembly for preventing rotation, and undesired locking, of a shaft. The travel stop assembly may comprise a shaft that extends along an axis and is rotatable about the axis. A lead screw may extend along the axis and be operatively engaged, and rotatable, with the shaft about the axis. A nut may be in threaded engagement with the lead screw and axially movable along a length of the lead screw upon rotation of the lead screw. At least one stop pin may operatively engaged the lead screw and the at least one stop pin may extend from the lead screw perpendicularly relative to the axis. The stop pin may be positioned on the lead screw to stop rotation of the lead screw and the stop pin may prevent locking of the nut to the lead screw.

A steer by wire type steering apparatus according to the present embodiments comprises a rotating shaft that rotates in conjunction with a steering shaft, a housing provided with a ball seating portion at one end and a ball is coupled and supported between the ball seating portion and an inner circumferential surface of the rotating shaft, a support member disposed inside the housing and provided with a protruding support portion for supporting the ball to one side in a circumferential direction while protruding in an axial direction, a ball support elastic member coupled to the housing and elastically supporting the ball to another side in the circumferential direction, and an actuator for moving the support member in the axial direction.

A method includes determining a current slew rate associated with a motor of the steering column, determining a speed slew rate associated with the motor, determining a current and speed slew rate threshold for the motor, and determining whether the current slew rate or the speed slew rate indicates a pinch event based on a comparison of the current slew rate, the speed slew rate, and the current and speed slew rate threshold. The method also includes, in response to a determination that at least one of the current slew rate and the speed slew rate indicates a pinch event, selectively instructing the motor to one of stop operation and reverse operation for a calibration period and, in response to the pinch event having a magnitude that is less than a pinch event threshold, selectively instructing the motor to continue operation.

An apparatus of limiting a steering angle in a steer-by-wire (SBW) system, may include a steering column rotating in association with a steering wheel; a striker which is provided to penetrate the steering column and rotates together with the steering column, and has a guide pin and a stopper pin; and a disk member that has a spiral sliding slot formed on a surface facing the guide pin, and a stopper formed on a position limiting a maximum steering angle of the steering column in a process of the guide pin rotating along the sliding slot and the striker being translated with respect to the steering column, so that the stopper pin is caught by the stopper in the rotation and translation motions of the striker.

The disclosure relates to a steering apparatus with a blocking device for limiting a steering angle of rotation, wherein the blocking device has a blocking element movable between a locking position and a release position, and with a shaft which is mounted rotatably about its centre longitudinal axis. When in the locking position, the blocking element interacts with a blocking contour in order to stop a rotational movement of the shaft. The blocking element is movable by the actuator for interaction with the blocking contour. The steering angle of rotation for the steering apparatus can be limited in two directions of rotation directed facing away from each other by the blocking element, wherein both a first end stop position in a first direction of rotation and a second end stop position in a second direction of rotation opposed to the first direction of rotation can be predefined by the blocking element and in interaction with the blocking contour.

A steering column assembly includes a jacket extending longitudinally about a jacket axis, the jacket defining an opening extending radially completely through the jacket. The steering column assembly also includes an end stop assembly disposed in the opening and protruding radially inwardly. The steering column assembly further includes a steering shaft, at least a portion of the steering shaft disposed within the jacket and extending longitudinally about the jacket axis. The steering column assembly yet further includes a stop ring mounted to the steering shaft, the stop ring positioned to contact the end stop assembly at an end of rotational travel position of the steering shaft.

A steer-by-wire rudder system includes a first system having a first motor unit that drives a rudder mechanism and a first control unit that controls the first motor unit, and a second system having a second motor unit that drives the rudder mechanism and a second control unit that controls the second motor unit. The first control unit and the second control unit perform cooperative control for controlling the first motor unit and the second control unit to cooperate with each other. When the cooperative control is not performed, one of the control of the first motor unit by the first control unit and the control of the second motor unit by the second control unit continues, and the other thereof stops.

The embodiments relate to a steering control device and method of a vehicle. A steering control device may include a receiver configured to receive absolute steering angle information, relative steering angle information, and rack position information of the vehicle, a determiner configured to determine absolute steering angle estimation information based on the rack position information and the relative steering angle information if there is an abnormality in the absolute steering angle information, and a controller configured to, if an adjustment condition is satisfied for at least one of a rack limit position and a steering wheel limit position, perform a position adjustment control based on the rack position information and the absolute steering angle estimation information.

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.

A steer-by-wire steering system for a motor vehicle may include a rotatably supported steering spindle, a feedback actuator with a feedback motor for acting on the steering spindle, a steering actuator with a steering motor for acting on steered wheels of the motor vehicle based on rotation of the steering spindle, and two control units for controlling the feedback motor and the steering motor. A first control unit of the two control units and a second control unit of the two control units have different levels of complexity relative to each other, in particular such that the first control unit is more powerful than the second control unit. Also, a method can be utilized to operate such a steer-by-wire steering system, whereby the first control unit and the second control unit execute procedures of different complexity relative to each other.
