The invention relates to the technical field of vehicle control, and discloses a vehicle steering control method and system, a vehicle and a storage medium, the method is applied to the vehicle provided with a front wheel hydro-pneumatic suspension, a rear wheel hydro-pneumatic suspension and a hydro-pneumatic suspension central controller, and the hydro-pneumatic suspension central controller is connected with an electric power steering system. The method comprises the steps that a steering wheel steering angle transmitted by the electric power steering system is obtained; predicting a target roll angle according to the steering wheel steering angle; and the target roll angle is sent to a target hydro-pneumatic suspension in the front and rear wheel hydro-pneumatic suspensions, and the target hydro-pneumatic suspension is controlled to adjust the vehicle to a preset balance state according to the target roll angle. The whole vehicle steering roll angle of the vehicle is predicted through the steering wheel steering angle, and then the front and rear wheel hydro-pneumatic suspensions of the vehicle are actively controlled based on the predicted target roll angle, so that it is guaranteed that the vehicle is stable during steering. The steering characteristics of the whole vehicle can be actively balanced, the steering control efficiency of the vehicle is improved, and the steering stability and driving safety of the vehicle are improved.
本申请涉及车辆控制技术领域,本申请公开了一种车辆转向控制方法、系统、车辆和存储介质,该方法应用于设置有前后轮油气悬架和油气悬架中央控制器的车辆,油气悬架中央控制器与电动助力转向系统连接,该方法包括:获取电动助力转向系统传输的方向盘转向角;根据方向盘转向角预测目标侧倾角;将目标侧倾角发送至前后轮油气悬架中的目标油气悬架,根据目标侧倾角控制目标油气悬架将车辆调节至预设平衡状态。本申请通过方向盘转向角预测车辆的整车转向侧倾角,再基于预测的目标侧倾角主动对车辆的前后轮油气悬架进行控制,以保证车辆在转向时平稳。本申请可主动平衡整车转向特性,提高车辆转向控制效率,提升车辆转向稳定性和驾驶安全性。
