Electric adjusting steering column device and control method

Abstract

The invention relates to an electric adjusting steering column device and a control method, and the electric adjusting steering column device comprises an upper column body assembly, a lower column body assembly, a mounting bracket, a controller, a telescopic direction adjusting motor, a second nut lead screw transmission assembly, an inclination direction adjusting motor and a first nut lead screw transmission assembly. A steering wheel is mounted on the upper column body assembly; the inclination direction adjusting motor drives the upper pipe column body and the lower pipe column body to rotate relative to the installation support around a connecting rotating shaft of the lower pipe column body and the installation support through the first nut lead screw transmission assembly, and electric adjustment in the inclination direction is achieved. A telescopic direction adjusting motor drives the upper pipe column body to do linear reciprocating motion relative to the telescopic direction of the lower pipe column body along the axis of the lower pipe column body through the second nut lead screw transmission assembly, so electric adjustment in the telescopic direction is realized; a driver can electrically adjust the position of the steering wheel through the adjusting button, operation convenience and man-machine comfort of the driver are improved, and adjustment of the steering wheel is more intelligent and personalized.

Description

[technical field] [0001] The invention relates to the technical field of automobile manufacturing, in particular to an electric adjustment steering column device and a control method. [Background technique] [0002] With the development of electrification and intelligence in the automobile industry, intelligent driving and intelligent cockpit have become the core technologies that major automobile companies will vigorously develop in the next few years. Among them, the steering column, as an important part of the smart cockpit, is arranged in the cockpit, connecting the steering wheel in the cockpit and the steering gear in the engine compartment, and the driver's steering torque is transmitted to the steering wheels through the steering column and the steering gear. , to realize the steering of the car. In addition to the basic function of the steering column to convey the driver's intentions, another indispensable function is to adjust the position of the steering wheel i...

Problems solved by technology

[0004] This adjustment method requires manual release of the adjustment handle and manual pull of the steering wheel to adjust the position of the steering wheel, which is inconvenient to adjust. At the same time, the position of the steering wheel cannot be customized and controlled by software, which does not match the development concept of the smart cockpit.
