The invention relates to the technical field of vehicle control, and discloses a vehicle braking nodding 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 a brake pedal position sensor. The method comprises the steps that the current pedal stroke collected by a brake pedal position sensor is obtained; predicting a target nodding angle according to the current pedal travel; and the target nodding 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 nodding angle. The whole vehicle braking nodding angle of the vehicle is predicted according to the current pedal travel, and finally, the front and rear wheel hydro-pneumatic suspensions of the vehicle are actively controlled based on the target nodding angle, so that dynamic stability during vehicle braking is ensured. The vehicle braking nod characteristic is actively balanced, the vehicle braking control efficiency is improved, and the vehicle control stability and the braking smoothness 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制动点头控制方法、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制动踏板位置传感器连接,该方法包括:获取制动踏板位置传感器采集的当前踏板行程;根据当前踏板行程预测目标点头角;将目标点头角发送至前后轮油气悬架中的目标油气悬架,根据目标点头角控制目标油气悬架将车辆调节至预设平衡状态。本申请根据当前踏板行程预测车辆的整车制动点头角,最后基于目标点头角主动对车辆的前后轮油气悬架进行控制,保证车辆制动时动态平稳。本申请主动平衡整车制动点头特性,提高车辆制动控制效率,提升车辆操控稳定性和制动平顺性。
