The invention relates to a dynamic adjust gyroscope life forecasting method based on gray model. By data collection of vibration effective value, random drift and environmental temperature parameter which are preprocessed using radial neural networks, influence of environmental temperature on vibration effective value and random drift is eliminated and random drift and effective value just related to time are obtained by subtracting drift constant value term, then trend term of vibration effective value and random drift are extracted by using wavelet transformation and gray model are built separately for their trend term. The smaller data in two values of life predicted of dynamic adjust gyroscope unless two predicted values exceeding performance parameter limitation when dynamic adjust gyroscope is considered losing effect. The invention uses performance parameter of life probative period of product to predict its life, showing discipline of performance parameter and life of dynamic adjust gyroscope. It is easy and convenient economical and reliable.

The invention provides an automobile air conditioner control method and device, a storage medium and an automobile air conditioner. The automobile air conditioner control method comprises the following steps of obtaining current environment temperature outside an automobile and current heating accumulation operation time of the air conditioner; and determining whether an air outlet and / or an airinlet of the air conditioner are covered with ice and snow or not according to the current environment temperature outside the automobile and the current heating accumulation operation time. The scheme provided by the invention can be used for solving the problem that due to the fact that the air outlet and / or the air inlet of the automobile air conditioner are covered with ice and snow, the problem that the heating effect of the air conditioner is reduced is solved.
