When a vehicle runs in such an environment, snow easily intrudes into a passenger compartment, an engine compartment, a luggage compartment, a cooling fan, an air filter, and the like of the vehicle. The dry snow is accumulated on the cooling fan and moving parts around the engine, because the temperature around the engine is higher, the accumulated snow is adhered to fan blades, the motor and other engine accessories after melting, when the temperature of each part is reduced after the engine stops working, snow water adhered to the part is condensed into ice blocks, and after the engine is restarted, the ice blocks condensed on the part seriously influence the normal work of rotating parts such as the fan, a belt and the like and corrode metal parts. If dry snow invades and accumulates in the air filter box and is further solidified, the air inlet performance of the engine is affected, the dynamic property of the engine is reduced, and the engine is flamed out and the vehicle stops running in severe cases. Therefore, the vehicle needs to be subjected to a snow raising test for checking the influence of snow entering each cabin of the vehicle on the vehicle when the vehicle is running in a dry snow environment.

In addition, the existing snow raising test is lack of the assessment on the performance of the whole vehicle except for assessing whether an obvious failure mode exists.
