The invention discloses a switch solenoid valve fault diagnosis method, device and equipment, a storage medium and a product, and relates to the technical field of vehicle detection, and the method comprises the steps: sending a detection instruction to a to-be-detected vehicle, so as to detect a cooling and lubricating loop of a cooling and lubricating system in the to-be-detected vehicle; when the cooling and lubricating loops pass the detection, the current driving working condition of the to-be-detected vehicle is obtained; the switch solenoid valve of the to-be-detected vehicle is diagnosed based on the current driving working condition, whether the switch solenoid valve has faults or not is judged based on the diagnosis result, and the faults of the switch solenoid valve comprise valve element clamping stagnation, coil short circuit and coil open circuit. When the cooling and lubricating loop of the cooling and lubricating system in the to-be-detected vehicle is determined to be normal, the on-off solenoid valve of the to-be-detected vehicle is diagnosed based on the current driving working condition of the to-be-detected vehicle, so that whether the on-off solenoid valve has a fault or not is judged, and fault diagnosis can be accurately performed on the on-off solenoid valve in the face of a complex oil way.

    本申请公开了一种开关电磁阀故障诊断方法、装置、设备、存储介质及产品,涉及车辆检测技术领域,所述方法包括:向待检车辆发送检测指令,以对待检车辆中冷却润滑系统的冷却润滑回路进行检测;当冷却润滑回路均通过检测时,获取待检车辆的当前行车工况;基于当前行车工况对待检车辆的开关电磁阀进行诊断,并基于诊断结果判断开关电磁阀是否存在故障,开关电磁阀的故障包括阀芯卡滞、线圈短路和线圈断路。本申请在确定待检车辆中冷却润滑系统的冷却润滑回路正常时,基于待检车辆的当前行车工况对待检车辆的开关电磁阀进行诊断,从而判断开关电磁阀是否存在故障,因此在面对复杂油路时也能准确地对开关电磁阀进行故障诊断。
