The invention discloses a vehicle retarded braking control method and system, electronic equipment, a storage medium and a vehicle, and the method comprises the steps: responding to an auxiliary braking switch state, judging whether a retarded braking mode entering condition is met, and when the retarded braking mode entering condition is met, controlling the retarded braking mode on the basis of a current road condition and a driving demand. The corresponding retarding braking mode is selected, and the selected retarding braking mode is matched with the current vehicle state; in response to the selected retarding braking mode, the required braking power is calculated according to the vehicle state; and on the basis of the required braking power, a driving motor and a hydraulic retarder are controlled in a coordinated mode to conduct retarding braking, and the retarding braking mode is quitted according to quitting conditions. Motor braking and hydraulic retarder braking can be simultaneously or independently controlled according to specific working conditions, the retarding braking performance of the pure electric engineering vehicle is enhanced, meanwhile, electric energy can be recycled as much as possible through motor braking, and power consumption of the whole vehicle is reduced.

    本发明公开了一种车辆缓速制动控制方法、系统、电子设备、存储介质及车辆,包括响应于辅助制动开关状态,判断是否满足进入缓速制动模式条件,当满足所述进入缓速制动模式条件时,基于当前道路条件以及驾驶需求,选择相应的所述缓速制动模式,其中,选择的所述缓速制动模式与当前车辆状态相匹配;响应于选择的所述缓速制动模式,根据所述车辆状态计算需求制动功率;基于所述需求制动功率,协调控制驱动电机以及液力缓速器进行缓速制动,并根据退出条件,退出所述缓速制动模式。本发明可根据具体工况同时或单独控制电机制动和液力缓速器制动,增强纯电动工程车辆缓速制动性能,同时能尽量通过电机制动回收电能,降低整车电耗。
