Belt pulley slipping diagnosis method and device, vehicle and storage medium

The invention belongs to the technical field of vehicles, and discloses a belt pulley slipping diagnosis method and device, a vehicle and a storage medium. The belt pulley slipping diagnosis method comprises the steps that an engine is started, a slipping standard value before wading is obtained, and a wading control mode is entered; the siphon automatically sucks water from the water tank and sprays the water to the belt pulley, the current slip value after wading is obtained, it is determined that the current slip value after wading is not equal to the slip standard value before wading, and it is judged that the belt pulley is in a slip state for eliminating potential faults of an engine. And the problem that the wading belt pulley and belt are condensed and frosted due to extremely low temperature in winter in northern China is solved, and whether the belt pulley slips or not can be diagnosed in an outdoor field in winter. 本发明属于车辆技术领域，公开了一种皮带轮打滑诊断方法、装置、车辆及存储介质，该皮带轮打滑诊断方法包括启动发动机，获取涉水前的打滑标准值，进入涉水控制模式，涉水控制模式包
