Automobile internal and external circulation adaptive switching method and device

Abstract

The invention relates to the field of automobile control, in particular to an automobile control method. The method includes the steps that the intra-automobile temperature and the extra-automobile temperature are obtained; whether the extra-automobile temperature is higher than a first preset temperature or not is judged; if the extra-automobile temperature is higher than the first preset temperature, whether the temperature difference between the intra-automobile temperature and the extra-automobile temperature is higher than a preset temperature difference or not is judged, if the temperature difference between the intra-automobile temperature and the extra-automobile temperature is higher than the preset temperature difference, the circulation mode of an automobile is automatically switched into an external circulation mode, and if the extra-automobile temperature is not higher than the first preset temperature, whether the extra-automobile temperature is lower than a second presettemperature or not is judged; and if the extra-automobile temperature is lower than the second preset temperature, the circulation mode of the automobile is automatically switched into an internal circulation mode. The invention further relates to an automobile control device which comprises a temperature acquisition module, a judgment module, a detection module and a mode switching module. The temperature reduction rate is increased, and the problems of the low oxygen content in the automobile and the quick electric quantity consumption are solved.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a method and device for self-adaptive switching between internal and external cycles of an automobile. Background technique [0002] We all know that every car is equipped with an air-conditioning system, which can ensure that we can have a better driving environment in severe cold and heat. The air-conditioning system is divided into external circulation and internal circulation. The external circulation refers to absorbing air from the outside of the car, directing it to the air-conditioning system for heating or cooling, and then blowing it out from the air outlet to replenish fresh air into the car and improve the air quality in the car. The main function of the internal circulation is to effectively prevent external dust and harmful gases from entering the car in a timely and effective manner, and perform air circulation in the car to better maintain the temperature inside ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that in the prior art, after the vehicle is exposed to the sun, the temperature in the vehicle cools down slowly, and the cooling efficiency is low. Execution of the same cycle mode for a long time is likely to cause hypoxia, and the same cycle switching mode is executed when the temperature is suitable, which wastes electric energy. The problem
