The invention relates to a control method and device of a vehicle and a storage medium, and the control method of the vehicle comprises the steps that according to the fact that a hydraulic retarder of the vehicle is in a starting state, environment parameters of the current vehicle are obtained; determining a cooling liquid temperature threshold according to the environmental parameters of the current vehicle; the cooling liquid temperature of the vehicle is obtained; and according to the condition that the cooling liquid temperature of the vehicle is not higher than the cooling liquid temperature threshold value, a cooling fan of the vehicle is controlled to enter a non-full-rotation state. According to the control method of the vehicle provided by the embodiment of the invention, the control strategy of the cooling fan can be corrected according to the relation between the current environment condition and the temperature of the cooling liquid while the hydraulic retarder of the whole vehicle is started, so that accurate control of the strategy can be realized according to different boundary conditions; therefore, the problem that accessory power consumption is increased due to the fact that the rotating speed of the cooling fan is in a two-stage mode is solved, and the economical efficiency of the whole vehicle is improved. And meanwhile, the heat preservation difficulty of engine aftertreatment can be reduced.

    本发明涉及一种车辆的控制方法、装置及存储介质,其中,该车辆的控制方法包括:根据所述车辆的液力缓速器处于开启状态,获取当前车辆的环境参数;根据当前车辆的环境参数确定冷却液温度阈值;获取车辆的冷却液温度;根据车辆的冷却液温度不高于所述冷却液温度阈值,控制所述车辆的冷却风扇进入非全转状态。根据本申请实施例提供的车辆的控制方法,可以在整车开启液力缓速器的同时,根据当前环境状况同冷却液温度的关系对冷却风扇的控制策略进行修正,以能够根据不同边界条件实现策略的精准控制,从而避免冷却风扇的转速呈现出两级形式,导致增加附件功率消耗的问题出现,进而提升整车的经济性。同时,也可以减少发动机后处理的保温难度。
