The invention provides an electric vehicle retarding control method and device, electronic equipment and a storage medium, under the condition that an electric vehicle meets a retarding braking condition, a retarding set vehicle speed is output, and the retarding set vehicle speed is the vehicle speed of the electric vehicle at the beginning of a speed raising trend in a sliding state; the method comprises the following steps of: performing incremental PID (Proportion Integration Differentiation) calculation on a motor torque of the electric vehicle by taking a slow-moving set vehicle speed as a speed target to obtain a speed regulation required torque; and with the speed regulation required torque as a torque target, the sliding energy recovery torque of the electric vehicle is adjusted to obtain the retarding required torque. The retarding braking function can be automatically triggered in the running process of the electric automobile, the sliding intention of a driver under the normal working condition is not interfered, meanwhile, the method is suitable for torque setting of different retarding requirements under different gradients, the motor participates in braking energy recovery to the maximum extent, and power consumption is reduced.

    本发明提供一种电动汽车缓速控制方法、装置、电子设备及存储介质,在电动汽车满足缓速制动条件的情况下,输出缓行设定车速,该缓行设定车速为电动汽车在滑行状态下、升速趋势开始时的车速;以缓行设定车速为速度目标,对电动汽车的电机扭矩进行增量型PID计算得到调速需求扭矩;以调速需求扭矩为扭矩目标,对电动汽车的滑行能量回收扭矩进行调整得到缓速需求扭矩。本发明可以在电动汽车行驶过程中自动触发缓速制动功能,而不干涉正常工况下驾驶员滑行意图,同时适用于不同坡度下不同缓速需求的扭矩设定,并且最大程度电机参与制动能量回收、降低电耗。
