The invention relates to a water leakage diagnosis method, device and equipment and a storage medium, and the method comprises the steps: controlling an electronic water pump in a cooling system in a vehicle to operate under the condition that an oil-electric hybrid vehicle is powered on and the vehicle meets a first preset condition, so as to drive cooling liquid of a heating ventilation cooling cycle in the cooling system to circulate; the first preset condition comprises one or more of the conditions that the shutdown duration of the vehicle is longer than the preset duration, the temperature of the cooling liquid is smaller than a preset temperature threshold value, and the upper circulation water leakage fault flag bit is true; under the condition that the obtained first operation parameter of the electronic water pump meets a second preset condition, it is determined that cooling liquid leakage occurs in the cooling system; the second preset condition is that the rotating speed in the first operation parameter is larger than a first preset rotating speed threshold value, and the current in the first operation parameter is smaller than a first preset current threshold value. The cooling liquid leakage diagnosis is carried out through the operation parameters of the original electronic water pump in the cooling system, additional parts do not need to be added, the cooling liquid leakage diagnosis can be carried out in advance after the vehicle is powered on, the cooling liquid leakage of the cooling system can be predicted in time, and the timeliness of water leakage diagnosis is improved.

    本发明涉及一种漏水诊断方法、装置、设备及存储介质,方法包括:在油电混动的车辆上电且车辆满足第一预设条件的情况下,控制车辆内冷却系统中的电子水泵运转,以驱动冷却系统中暖通冷却循环的冷却液流通;第一预设条件包括车辆的停机时长大于预设时长、冷却液的温度小于预设温度阈值,上循环漏水故障标志位为真中的一项或者多项;在获取到的电子水泵的第一运转参数满足第二预设条件的情况下,确定冷却系统出现冷却液泄漏;第二预设条件为第一运转参数中的转速大于第一预设转速阈值,且第一运转参数中的电流小于第一预设电流阈值。本发明通过冷却系统中原有的电子水泵的运转参数来进行冷却液泄漏诊断,无需增加额外部件,且在车辆上电后即可预先执行,能够及时预见冷却系统的冷却液泄漏,提高了漏水诊断的及时性。
