Intelligent control method of air-conditioner

Abstract

The invention discloses an intelligent control method of an air-conditioner. The intelligent control method comprises the steps of connecting the air-conditioner to the entire vehicle CAN network, obtaining an air-conditioner set temperature T1 and an environment temperature T2 by an entire vehicle controller, and calculating the temperature difference delta T of the two temperatures, when the temperature difference delta T is greater than the set temperature difference limiting value, starting the air-conditioner, otherwise, comparing the environment temperature T2 with the set environment temperature limiting value, when the environment temperature T2 I s greater than the set environment temperature limiting value, controlling the air-conditioner to be started, otherwise, comparing the previous response time of the air-conditioner with the set response time limiting value, and when the previous response time of the air-conditioner exceeds the set response time limiting value, starting the air-conditioner, otherwise, prohibiting the starting of the air-conditioner. The intelligent control method of the air-conditioner has the advantages that the energy source is reasonably and effectively distributed and intelligent control is performed on the air-conditioner according to the actual conditions of the air-conditioner (the set temperature, the temperature and the like) and the entire vehicle on the basis of information interaction between the entire vehicle controller and the air-conditioner controller, and furthermore, the effects of energy conservation and emission reduction can be achieved.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning control, in particular to an air-conditioning intelligent control method. Background technique [0002] In the new energy vehicle system: the control of the air conditioner is mainly completed by the air conditioner controller; the air conditioner controller turns on and off the air conditioner according to the user's set temperature and the detected ambient temperature. During the period when the air conditioner is turned on, the engine must be started. Drive the air conditioner compressor to work normally and provide the power required by the air conditioner. Therefore, when the air conditioner is turned on, the start-stop function cannot be realized. lead to a lot of waste of energy. [0003] The existing technology adopts the method of air conditioner request: when the air conditioner needs to be turned on, the air conditioner controller sends out an air conditioner request signal,...

AI Technical Summary

Problems solved by technology

Since the vehicle controller does not understand the actual operating status of the air conditioner, it only passively receives the request signal, resulting in the formation of an information island between the vehicle control and the air conditioner controller, and the vehicle control cannot accurately control the air conditioner, which also causes energy waste
