Electric-adjusting steering column control method and device and electric-adjusting steering column

Abstract

The invention discloses an electric-adjusting steering column control method. The method includes acquiring a vehicle switch signal; judging whether the vehicle switch signal meets a first preset condition or second preset condition or not; when the first preset condition is met, controlling a first motor to operate to allow the steering column to move in the direction far from a driving position till a first limiting position, and controlling a second motor to operate to allow the steering column to move in the direction far from the driving position till a second limiting position; when the second preset condition is met, controlling the first motor to operate to allow the steering column to move towards the driving position till a third limiting position, and controlling the second motor to operate to allow the steering column to move towards the driving position till a fourth limiting position. By the aid of the control method, the automatic control of the electric-adjusting steering column can be implemented. The invention further discloses a control device of the electric-adjusting steering column and the electric-adjusting steering column.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle steering control, and in particular relates to a control method and device for electrically adjusting a steering column and an electrically adjusting steering column system. Background technique [0002] The position of the steering wheel in a traditional motor vehicle is fixed, because the steering wheel is close to the driving position, which causes the driver to avoid sideways in the process of getting on and off the car, so as to get on and off the car smoothly. [0003] In order to make it easier for the driver to get on and off the car, there is currently an electrically adjustable steering column, which includes a steering column and two motors, one motor can drive the steering column to move telescopically along its axis, such as figure 1 As shown, another motor can drive the steering column to rotate around the connection with the chassis direction drive mechanism, as shown in fig...

AI Technical Summary

Problems solved by technology

[0004] However, at present, the driver must manually control the operation of the two motors during the process of getting on and off the vehicle. How to automatically control the operation of the electric adjustment steering column is a problem that those skilled in the art need to solve.
