Steering control methods, devices, vehicles and storage media

Abstract

This application relates to the field of vehicle technology, and particularly to a steering control method, device, vehicle, and storage medium. The method includes: acquiring vehicle data, including current vehicle speed and current steering wheel angle; determining a target steering wheel rotation amplitude based on the current steering wheel angle's rotation angle range, and determining a target gear ratio calculation strategy based on the current vehicle speed's speed range and the target steering wheel rotation amplitude; calculating the front wheel angle based on the target gear ratio calculation strategy and the vehicle data, and controlling the vehicle to perform steering control based on the front wheel angle. This solves the problem that a fixed angular gear ratio cannot simultaneously achieve both low-speed agility and high-speed stability at different vehicle speeds. It provides a smaller gear ratio at low speeds to enhance agility and a larger gear ratio at high speeds to improve stability, ultimately providing optimal handling stability for the vehicle under all operating conditions.
