The invention discloses a vehicle braking air pressure early warning method, device and equipment and a storage medium. The method comprises the steps that whether the current driving working condition air pressure of a vehicle is larger than the set air pressure or not is judged; if yes, the actual driving early warning air pressure is output based on the current vehicle load signal and the calibrated load-air pressure MAP; and based on the loop air pressure before and after driving, fitting to obtain a curve of theoretical pressure and actual pressure after leakage, and calculating a vehicle brake air pressure early warning value through the curve and the actual driving early warning air pressure so as to perform early warning. Different self-adaptive calibration early warning values can be carried out according to working conditions, a user is effectively reminded of the braking air pressure at the current stage, the driving deceleration requirement is met, and the risk of misinformation is reduced.

    本发明公开了一种车辆制动气压预警方法、装置、设备及存储介质,其中该方法包括步骤:判断车辆当前的行车工况气压是否大于设定气压;若是,则基于当前车辆载重信号以及标定的载重‑气压MAP图,输出实际行车预警气压;基于行车前后回路气压,拟合得到理论压力与泄漏后实际压力的曲线,并通过所述曲线和所述实际行车预警气压,计算车辆制动气压预警值,以进行预警。本申请能够根据工况进行不同的自适应标定预警值,有效提醒用户现阶段制动气压,支撑行车减速度需求,并且降低了误报的风险。
