The invention discloses an electric vehicle dragging torque control method and device and a storage medium, and the method comprises the steps: building the oil pressure of a hydraulic braking system when a vehicle speed threshold value is met, enabling the hydraulic braking system and a DTC to work cooperatively so as to generate expected braking force, and when the vehicle is recognized to step from a low-adhesion road condition to a high-adhesion road condition, controlling the hydraulic braking system to work cooperatively. The braking force is gradually smaller than that of a hydraulic braking system; and the braking force of electric braking is correspondingly increased. According to the invention, sufficient braking force can be obtained when the vehicle enters the high-pressure vehicle, the kinetic energy of the vehicle can be fully recovered, and the energy efficiency of the vehicle is improved.

    本发明公开了一种电动汽车拖滞扭矩控制方法、装置及存储介质,包括在满足车速门限值时通过建立液压制动系统的油压使液压制动系统与DTC协同工作,以产生预期的制动力,并且在识别到车辆由低附路况阶跃到高附路况时,逐渐小于液压制动系统的制动力以及相应的增加电制动的制动力。本发明既能保证车辆进入高附时获得足够的制动力,并且可以充分的回收车辆的动能,提高车辆的能效。
