The invention discloses a vehicle braking anti-skid control method and system, a vehicle and a storage medium, and the method comprises the steps that driving data and basic data of the vehicle are obtained, the driving data comprise the vehicle speed, the acceleration, the steering wheel angle, the yaw velocity and the actual wheel speed, and the basic data comprise the wheelbase and the wheel track; according to the driving data and the basic data, the slippage state of the electric vehicle is determined, and the slippage state comprises braking slippage and non-slippage; in response to the fact that the slip state is brake slip, target single-wheel output brake torque is determined; determining a target braking torque limit value of the power motor in response to the condition that the slip state is braking slip; and controlling the electric vehicle according to the target single-wheel output brake torque and the target brake torque limit value. The technical problem that in the prior art, due to the fact that large delay exists in hydraulic response, the control effect is poor, and the increasingly-improved requirements of users for driving quality and driving safety are difficult to meet is solved.

    本发明公开了一种车辆制动防滑控制方法、系统、车辆及存储介质,其中,方法包括:获取车辆的行驶数据和基础数据,其中,行驶数据包括车速、加速度、方向盘转角、横摆角速度和实际轮速,基础数据包括轴距和轮距;根据行驶数据和基础数据,确定电动车辆的滑移状态,其中,滑移状态包括制动滑移和未滑移;响应于滑移状态为制动滑移,确定目标单轮输出制动扭矩;响应于滑移状态为制动滑移,确定动力电机的目标制动扭矩限值;根据目标单轮输出制动扭矩和目标制动扭矩限值,对电动车辆进行控制。本发明解决了现有技术中,由于液压响应存在较大延迟,控制效果差,已难以满足用户日益提升的对于驾驶品质和行驶安全的要求的技术问题。
