Embodiment Construction

[0010] Referring now to the drawings, in which the invention will be described with reference to, but not limited to, specific embodiments, figure 1 Depicted is a steering column disengagement system 10 for a vehicle that benefits from selectively switching the state of the steering column 12 between a coupled position and a disengaged position. For example, a vehicle having a steering system that includes steer-by-wire and / or autonomous driving features may benefit from the embodiments described herein.

[0011] A steer-by-wire system employs a control system and servos that interface with the vehicle so that the vehicle can be steered without a mechanical connection to the steering wheel 14, but instead relies on an electrical connection between the steering wheel 14 and the steering gear.

[0012] In some embodiments, the steering column disengagement system 10 may be part of an autonomous driver assisted steering (ADAS) system capable of steering and controlling other para...

Abstract

A steering column decoupling system includes a steering shaft. Also included is an intermediate shaft. Further included is a driving disk operatively coupled to the steering shaft and rotatable therewith. Yet further included is a driven disk operatively coupled to the intermediate shaft and rotatable therewith, the driven disk disposed adjacent the driving disk. Also included is a slot defined by the driven disk. Further included is a coupling element coupled to the driving disk and disposed within the slot, the driven disk moveable relative to the coupling element between a column coupled position and a column decoupled position.

Description

technical field [0001] Embodiments described herein relate to vehicle steering systems, and more particularly, to a steering column disconnect system. Background technique [0002] It is desirable to switch between a mechanically coupled and decoupled steering column in a vehicle steering system. For example, vehicles equipped with Advanced Driver Assistance Steering (ADAS) systems may allow the steering column and steering wheel assembly to retract into a stowed position to enable the driver to perform non-steering activities such as reading, working, etc. When the steering wheel is stowed, it may be desirable to have the wheels in a non-rotatable state. This enables the vehicle to be steered with the aid of an ADAS system with a split steering axle. However, automatically transitioning between coupling and decoupling the steering column is challenging. Contents of the invention [0003] According to an aspect of the present disclosure, a steering column release system...
