According to the embodiments of the present invention, the drive feel suitable to given conditions is provided to a driver by generating friction when a steering shaft is rotated to enhance the drive feel of the driver, limiting the maximum steering angle, restoring the steering wheel automatically, and controlling friction on the steering shaft in accordance with the steering angle, vehicle speed and road conditions.

A steering system and a vehicle are provided. The steering system includes a steering wheel end shaft, a steering device end shaft, and an electric driving mechanism configured to drive decoupling or coupling of the steering wheel end shaft and the steering device end shaft that are coaxially disposed.

Disclosed are a clutch mechanism, a steering system, and an automobile. The clutch mechanism includes a slidable block and a driving component. The slidable block can be accommodated in a radial spacing between a first end shaft and a second end shaft that are coaxially arranged and radially spaced apart from each other, and is configured to translate along an axial direction of the first end shaft and the second end shaft to realize decoupling or coupling between the first end shaft and the second end shaft. The driving component is configured to drive the slidable block to translate along the axial direction of the first end shaft and the second end shaft.

The disclosure relates to a steering device comprising an end stop device for limiting a steering angle of rotation. The end stop device has a rotation device that has at least one rotary element which is rotatable about a central longitudinal axis of a shaft and/or is rotatable together with the shaft. The end stop device has a locking device which cooperates with the rotation device for stopping a rotational movement of the shaft about the central longitudinal axis and with respect to two directions of rotation oriented opposite each other. In order to be able to reliably absorb and transmit high forces and/or torques when the steering device is in a stop position, the locking device has a locking element, the locking element that limits the steering angle of rotation from being movable by the rotation device at least with a first movement component in the axial direction of the central longitudinal axis of the shaft.

An electric power steering apparatus and a control method thereof. A motor includes a first motor providing power to move a rack and a second motor providing power to move the rack in synchronization with the first motor. A sensor includes a torque angle sensor detecting a torque value and a steering angle in response to manipulation of a steering wheel and an angle sensor detecting an angle of rotation of a sector shaft. A controller controls the motor in response to the manipulation of the steering wheel, calculates an amount of compensation rotation of the motor by comparing the steering angle and the angle of rotation, and controls an amount of rotation of the motor in accordance with an amount of compensation rotation. The amount of rotation of a vehicle's wheel is controlled, so that actual intention of the driver in steering is accurately reflected.

A steering reaction force generation device for a vehicle may include a housing; a transfer shaft part rotatably installed in the housing, and disposed coaxially with a steering shaft; a stator part fixed to the inside of the housing; a rotor part connected to the transfer shaft part, and configured to rotate the transfer shaft part through an electromagnetic interaction with the stator part; and a power transfer part installed in the rotor part, and configured to transfer a rotational force of the transfer shaft part to the steering shaft.

A motor driven power steering control method may include setting a virtual steering system model including a column connecting a steering wheel to a rack gear, determining a column stiffness torque using torsional displacement of the column in the set virtual steering system model, and determining a target steering torque based on the determined column stiffness torque.

According to the embodiments of the present invention, the drive feel suitable to given conditions is provided to a driver by generating friction when a steering shaft is rotated to enhance the drive feel of the driver, limiting the maximum steering angle, restoring the steering wheel automatically, and controlling friction on the steering shaft in accordance with the steering angle, vehicle speed and road conditions.

A steer-by-wire steering system for a motor vehicle may include a steering column having a support unit and a steering shaft rotatably mounted in the steering column, a steering handle disposed in a rotationally fixed manner on the steering shaft, and a feedback actuator that is configured to apply a torque to the steering shaft. The feedback actuator here may be disposed outside the support unit, as a result of which installation space is available in the region of the steering column. The feedback actuator of the steer-by-wire steering system may in some cases be disposed on a bulkhead of a motor vehicle body.

A steering actuator for a steering system for a motor vehicle may include an actuator rod that can be displaced in translation in a longitudinal direction thereof and a position sensor apparatus that is constructed to detect a linear position of the actuator rod. In order to enable less complex production and a higher level of operational reliability, the position sensor apparatus may include a rotation sensor that has a sensor shaft that can be rotated about an axis and that has a running wheel that can roll on a corresponding linear track of the actuator rod to convert a translational movement of the actuator rod into a rotation of the sensor shaft.
