The invention relates to a control method, device and equipment of an electronic water pump, a storage medium and a vehicle, and relates to the technical field of vehicle control. The method is applied to an electronic water pump in a vehicle, the electronic water pump is connected with an electronic control unit through a first communication interface, the electronic water pump is connected with a relay through a second communication interface, the relay is connected with a storage battery, and the relay is used for being switched on when the vehicle is in a power-on state and switched off when the vehicle is in a power-off state. The method comprises the steps that under the condition that communication connection between the electronic water pump and the electronic control unit is interrupted, a level signal sent by the relay is obtained through the second communication interface, and the operation state of the electronic water pump is determined according to the level signal. The relay selected by the invention is a low-power-level relay, so that the cost can be effectively reduced, and the arrangement space is saved. Meanwhile, the implementation mode of arranging the second communication interface is simple, and the method can be suitable for more vehicles.

    本申请涉及一种电子水泵的控制方法、装置、设备、存储介质及车辆,涉及车辆控制技术领域。该方法应用于车辆中的电子水泵,电子水泵通过第一通信接口与电子控制单元连接,电子水泵通过第二通信接口与继电器连接,继电器与蓄电池连接,继电器用于在车辆处于上电状态下导通,以及在车辆处于下电状态下断开。该方法包括:在电子水泵与电子控制单元之间的通信连接中断的情况下,通过第二通信接口获取继电器发送的电平信号,并根据电平信号,确定电子水泵的运行状态。由于本申请选取的继电器为低功率层级的继电器,可以有效降低成本,并且节省布置空间。同时,布置第二通信接口的实施方式简单,可以适用于更多车辆。
