A hand-wheel actuator for preventing over rotation of a hand-wheel shaft. The hand-wheel actuator comprises a housing that defines an opening aligned about an axis. The hand-wheel shaft extends along and is rotatable about the axis. A drive gear is rotationally coupled to the hand-wheel shaft, wherein the drive gear is at least partially disposed in the opening and includes a drive gear tooth. A stop gear is coupled to the housing and includes a plurality of stop gear teeth for engagement with the drive gear tooth and prevents rotation of the drive gear over a predetermined threshold.

A linear actuator for a steer-by-wire system including a component, in particular an axle or a shaft, that can be moved along a linear trajectory, and including a measuring device for determining a position of the component. The measuring device has a coil for inductively determining the position of the component, and the coil is arranged coaxially relative to the linear trajectory of the component.

A steer-by-wire steering system for a vehicle, comprising: an operation member operable by a vehicle driver; an urging device configured to generate an urging force to urge the operation member; a steering device configured to steer a wheel; and a controller configured to control the urging device and the steering device. In a normal operation, the controller enables the wheel to be steered in accordance with an operation of the operation member and causes the urging force to function as an operation reaction force against the operation of the operation member. In an automatic steering operation in which the wheel is steered without depending on the operation of the operation member, the controller enables the operation member to be moved in accordance with steering of the wheel by the urging force and causes at least part of the urging force generated in the normal operation not to be generated.

According to the present embodiments, it is possible to enhance the driver's steering feel by limiting the maximum steering angle of the steering wheel and easily change the maximum steering angle of the steering wheel in real-time or with a minimum structure change as necessary.

A steering system includes a rotary shaft to which an operation member is coupled; a first actuator; a second actuator; a control unit; and a moving unit configured to move the operation member between a normal position and a storage area. The control unit is configured to switch between a manual drive mode and an autonomous drive mode. The control unit is configured to, when moving the operation member from the storage area to the normal position, start synchronous control when the operation member satisfies a predetermined condition before the operation member reaches the normal position, the synchronous control being control in which the control unit controls the first actuator to change a rotation angle of the rotary shaft to an angle corresponding to a steered angle of steered wheels driven by the second actuator.

An independent suspension system includes a wheel knuckle engaged with a wheel and configured to be rotated in response to a steering input; a motor assembly disposed at one end of the wheel knuckle and configured to rotate the wheel knuckle; an upper arm engaged with the motor assembly; a lower arm having a first end engaged with a vehicle body and a second end engaged with the wheel knuckle; a connection arm configured to be engaged with the upper arm; a rotation pin disposed at a connection portion between the upper arm and the connection arm to enable integral rotation of the upper arm and the connection arm; and a shock absorber disposed between the connection arm and the lower arm and engaged with the connection arm so as to be perpendicular to the connection arm.

The present disclosure provides a vehicle steering device and a vehicle steering method capable of ensuring safety of a passenger and a vehicle when a steering abnormality of the vehicle occurs. The vehicle steering device includes a steering input unit, a steering output unit connected to the steering input unit and a wheel, and a control unit configured to control the steering input unit and the steering output unit, in which, when a steering abnormality occurs in the steering input unit, the control unit directly controls the steering output unit regardless of the operation of the steering input unit.

A steer by wire type steering apparatus according to the embodiments of the present disclosure comprises an output shaft provided with fixing grooves on both sides, a moving member which moves in the axial direction when the output shaft is rotated and is provided with a guide portion protruding in the radial direction on an outer circumferential surface, a pair of guide stoppers for guiding the axial movement of the moving member, an elastic ring for elastically supporting the guide stoppers in a radial direction, and housing.

A vehicle steering assembly comprising an input shaft to be connected to a steering device, a first electric motor connected to the input shaft and arranged to provide a steering device torque and/or a steering device angle, an output shaft connected via a steering linkage to a number of ground engaging members, a rod placed between the input shaft and the output shaft, a first arm rotatably connected to the input shaft and rotatably connected to the rod, and a second arm rotatably connected to the rod and rotatably connected to the output shaft, a second electric motor connected to the output shaft and arranged to provide a steering control torque and/or a steering control angle, wherein the rod comprises a flexible drag link, which in combination with the first and second arm provide for forces in longitudinal direction to be absorbed.

Described is a rotation limitation module for a steer-by-wire steering system. Said rotation limitation module comprises a housing in which a shaft portion that is rotatable about a central axis and is able to be rotatably coupled to a steering wheel shaft or is configured as a portion of the steering wheel shaft is received. Furthermore provided is a limiter disk which by way of a sliding guide is coupled in a rotationally fixed and axially displaceable manner to the shaft portion and has an external thread which is driven into an internal thread of the housing. Moreover, the rotation limitation module comprises a first detent ring having a first detent wing, and a second detent ring having a second detent wing, both detent wings for limiting a rotation of the shaft portion being able to cooperate with the limiter disk. A steering wheel module for a steer-by-wire steering system is also disclosed, which comprises such a rotation limitation module.
