Abstract

The invention discloses a vehicle steering ratio adjusting method and device and a storage medium, relates to the technical field of vehicle steering, and solves the technical problem that the steering ratio needs to be repeatedly debugged in an existing steering-by-wire system, so that the user experience is improved. The method comprises the steps: receiving steering operation of a driver on a steering wheel, and acquiring a first steering wheel corner extreme value; based on the first steering wheel corner extreme value, determining a corresponding relation between a steering ratio and a working condition by combining a corresponding relation between a front wheel corner extreme value and the working condition; and in the vehicle driving process, adjusting the steering ratio of the vehicle according to the working conditions of the vehicle based on the corresponding relation between the steering ratio and the working conditions.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vehicle steering, and in particular, to a method, device and storage medium for adjusting a vehicle steering ratio. Background technique [0002] In a traditional automobile steering system, the steering wheel of the vehicle is mechanically connected to the front wheels, and the ratio between the steering wheel's rotation angle and the vehicle's front wheel's rotation angle (ie, the steering ratio) is a constant value when the driver manipulates the steering wheel. This steering system with a fixed steering ratio cannot meet the manipulation demands of different users. The proposal of the steer-by-wire system cancels the mechanical connection between the steering wheel and the front wheels, so that the steering ratio can be adjusted according to user needs, thus making the control of the vehicle more flexible. [0003] In the existing steer-by-wire system, the driver can input...
