The invention provides a vehicle steering method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that when obtained current operation information of a vehicle meets a preset triggering condition, the steering direction of the vehicle is determined according to the current operation information; based on a preset braking strategy, first braking force corresponding to the target front wheel and second braking force corresponding to the target rear wheel are determined; the target front wheel is controlled based on the first braking force, the target rear wheel is controlled based on the second braking force, and the vehicle is controlled to steer in the steering direction, so that the first slip rate of the target front wheel is smaller than the second slip rate of the target rear wheel. Precise control over the target front wheel and the target rear wheel through the first braking force and the second braking force is achieved through the preset braking strategy, the steering radius is reduced, meanwhile, the direction guiding capacity provided by the target front wheel and the transverse stability improving effect brought by the target rear wheel can be taken into account, and the steering efficiency is improved. The cooperative control advantage of the target front wheel and the target rear wheel is exerted to the maximum extent.
本发明提供了一种车辆转向方法、装置、车辆及存储介质,涉及车辆技术领域。该方法包括:当已获取的车辆的当前运行信息满足预设触发条件时,根据当前运行信息确定车辆的转向方向;基于预设制动策略分别确定目标前轮对应的第一制动力和目标后轮对应的第二制动力;基于第一制动力控制目标前轮,基于第二制动力控制目标后轮,并控制车辆朝转向方向进行转向,以令目标前轮的第一滑移率小于目标后轮的第二滑移率。本发明通过预设制动策实现第一制动力和第二制动力对目标前轮和目标后轮的精准控制,降低转向半径的同时,还能兼顾目标前轮提供的方向引导能力,以及目标后轮带来的横向稳定性的提升效果,最大程度上发挥目标前轮与目标后轮的协同控制优势。
