AI Technical Summary

Technical Problem

In existing technology, when the steering wheel of a vehicle is not in the correct zero position, the steering wheel needs to be disassembled for mechanical adjustment, which makes the adjustment process cumbersome and prone to damaging parts.

Method used

The system employs an electric variable drive motor in the front wheel active steering system. By determining the deviation angle, it triggers the corresponding adjustment mode and uses the electric variable drive motor to assist the steering wheel in returning to center. Combined with the wheel steering gear locking, this allows for steering wheel alignment without disassembly.

Benefits of technology

It simplifies the steering wheel alignment process, reduces maintenance costs, avoids parts damage, and improves driving safety and adjustment efficiency.

Abstract

This invention provides a method, device, and vehicle for aligning a vehicle steering wheel, belonging to the field of vehicle technology. It aims to adjust the steering wheel position without disassembling it when the steering wheel is misaligned. Applied to a front-wheel active steering system, the system includes an electric variable transmission motor for adjusting the angular transmission ratio between the steering wheel and the wheel steering mechanism. The method includes: determining the deviation angle between the current position and the preset position when the wheel is in the center position and the current position of the steering wheel deviates from the preset position; determining the triggered adjustment mode when the deviation angle is less than or equal to the preset angle; triggering a preset return-to-center strategy corresponding to the adjustment mode in response to the adjustment mode; controlling the electric variable transmission motor to assist the steering wheel in returning to the preset position based on the preset return-to-center strategy; and controlling the wheel steering mechanism to lock so that the wheel remains in the center position during the steering wheel return-to-center process.
