A stationary steering wheel assembly includes a steering wheel connected to an axially extending column. The assembly also includes a steering wheel locking component engageable with the steering wheel and moveable between a first position and a second position, the first position locking the steering wheel to prevent rotation and the second position unlocking the steering wheel to allow rotation of the steering wheel.

A lock device includes a locking member, a movable member, and a transmission mechanism. The locking member is moved between a lock position at which it locks a locking subject and an unlock position at which it unlocks the locking subject. The transmission mechanism transmits a drive force to the movable member and moves the movable member. A movement state of the movable member is shifted between a relative movement state in which it is moved relative to the locking member and an integral movement state in which it is moved together with the locking member to move the locking member toward the lock or unlock position. The lock device further includes a detector of which an output value varies in accordance with movement of the movable member or the transmission mechanism, and a controller that performs a failure determination based on a change in the output value.

A steering wheel control apparatus of an SBW (Steer-By-Wire) system may include a dominant controller configured to generate a wake-up signal, in response to an ignition switch of a vehicle being off, a motor driver configured to generate a steering reaction force against a steering wheel through a motor, and a steering wheel controller configured to generate the steering reaction force to interrupt a turn of the steering wheel, by controlling the motor driver according to the wake-up signal.

A steering shaft decoupling assembly includes a steering shaft. The assembly also includes a lower shaft mechanically coupled to the steering shaft. The assembly further includes a steering shaft locking component engageable with the steering shaft and moveable between a first position and a second position, the first position locking the steering shaft to prevent axial translation and the second position unlocking the steering shaft to allow axial translation of the steering shaft, the steering shaft locking component being in the second position in an autonomous driving mode, the autonomous driving mode comprising an advanced driving assist system controlling road wheels of a vehicle resulting in rotation of the lower shaft.

A system for estimating torque in a locked vehicle system may include a locking mechanism comprising a stiff material. The system may further include a controller configured to estimate an amount of torque in the locked vehicle system based on a deformation of the stiff material.

A steering lock device includes a position detector that detects a position of a lock member. The position detector includes a first unlock detecting portion of a digital output type that detects that the lock member is located in an unlock position and a second unlock detecting portion of an analog output type that detects that the lock member is located in an intermediate position, which is between a lock position and the unlock position. A position determination portion determines whether or not the lock member is located in the unlock position based on a detection signal of the first unlock detecting portion and a detection signal of the second unlock detecting portion, which has a parabolic output waveform that changes in accordance with movement of the lock member.

A steering column for a motor vehicle may include a steering shaft that is rotatably mounted in a boxed swing arm, a latching element connected to the steering shaft in a torsion-resistant manner, a locking element that may be brought into engagement with the latching element for temporary blocking of the steering shaft, a sensor arrangement that detects a steering parameter such as an angle of rotation of the steering shaft or a torque acting on the steering shaft, and an electromechanical actuator for actuating the locking element depending on a control. The sensor arrangement may comprise first sensors for detecting the steering parameter and at least one second sensor for detecting a position of the locking element in a structural unit (13).

A lock apparatus includes a bracket, an engagement module, and an actuation module. The engagement module is supported in the bracket and has an engagement member configured to move to a first position or a second position in a first axial direction along the first axial direction. The actuation module is connected to the bracket and includes a pushing member. The actuation module drives the pushing member to move to a first position or a second position in the second axial direction along the second axial direction. When the pushing member is at the first position in the second axial direction, the engagement member is at the first position in the first axial direction. When the pushing member is at the second position in the second axial direction, the engagement member is at the second position in the first axial direction.
