Electromagnetic semi-automatic clutch steering column for intelligent driving of vehicle

Abstract

The invention discloses an electromagnetic semi-automatic clutch steering column for intelligent driving of vehicle. The steering column comprises a fixed steering part, a floatable steering part, a return spring and an electromagnetic coil; the fixed steering part comprises a steering column body, a center guide rod arranged in the center of the steering column body and a non-magnetic-attractionspring guide rod arranged on the center guide rod, the return spring sleeves the non-magnetic-attraction spring guide rod, and the upper portion of the steering column body is provided with a meshed groove; the floatable steering part comprises a floatable steering sleeve and steering wheels, the center guide rod penetrates through the floatable steering sleeve, the inner wall of the floatable steering sleeve is provided with a first step surface and a second step surface, the electromagnetic coil is arranged on the first step surface, and the lower end of the floatable steering sleeve is provided with a meshed gear matched with the meshed groove; the center guide rod is provided with a third step surface; clutching of the steering wheels and the steering column body can be achieved, thatis to way, in an automatic driving mode, the steering wheels and the steering column body separately move; in a manual driving mode, the steering wheels and the steering column body synchronously move.

Description

Technical field [0001] The invention belongs to the field of automobile control, and in particular, relates to an electromagnetic semi-automatic clutchable steering column for intelligent driving automobiles. Background technique [0002] The steering column is an indispensable component in the vehicle steering system, and its role is to transmit the rotational movement of the steering wheel to the steering gear, thereby realizing the steering of the vehicle. During the operation of intelligent driving vehicles, it is often necessary to switch between automatic driving and manual driving. In the current intelligent driving vehicles, the steering wheel and the steering column are directly connected, regardless of whether it is in automatic driving mode or manual driving mode, the movement between the two is synchronized, that is, once the steering wheel rotates, the steering column will rotate; Once the steering column is turned, the steering wheel will turn, so when the vehicle ...

AI Technical Summary

Problems solved by technology

In the current intelligent driving vehicles, the steering wheel and the steering column are directly connected. Whether it is in the automatic driving mode or the manual driving mode, the movement between the two is synchronized, that is, once the steering wheel is turned, the steering column will turn; Once the steering column is turned, the steering wheel turns, so that when the vehicle is in autonomous mode, the steering wheel passively turns as the vehicle turns, compromising both aesthetics and the comfort and safety of the alternate driver
