The invention discloses a fuel cell vehicle purging control method and device, and relates to the technical field of fuel cell vehicles. The method comprises the steps that after a vehicle fuel cell system is shut down, the environment temperature of a vehicle is obtained; if the environment temperature is higher than the preset threshold value, whether the vehicle is powered off or not is judged; if the vehicle is powered off, judging whether the vehicle is temporarily parked or not; if the vehicle is parked temporarily, the fuel cell system is not purged; and if the vehicle is not parked temporarily, purging the fuel cell system. Under the conditions that the environment temperature is high and the vehicle is powered off, whether the vehicle is temporarily parked or not is judged, if the vehicle is temporarily parked, the vehicle can still be started to run within a short time, shutdown purging is not needed, a fuel cell system is not purged, the situation that the energy of the whole vehicle is excessively consumed due to frequent purging can be avoided, and the endurance of the whole vehicle can be improved.

    本发明公开了燃料电池汽车吹扫控制方法及装置,涉及燃料电池汽车技术领域。所述方法包括:车辆燃料电池系统停机后,获取车辆所在的环境温度;若环境温度高于预设阈值,则判断车辆是否已下电;若车辆已下电,则判断车辆是否为临时停车;若车辆为临时停车,则不对燃料电池系统进行吹扫;若车辆非临时停车,则对燃料电池系统进行吹扫。本发明在环境温度较高且车辆下电的情况下,判断车辆是否为临时停车,如果车辆为临时停车,车辆短时间内还会启动运行,无停机吹扫的必要,不对燃料电池系统进行吹扫,可以避免频繁吹扫过分消耗整车能量,有利于提高整车续航。
