Control method, device and system for vehicle-mounted air conditioner

Abstract

The invention provides a control method, device and system for a vehicle-mounted air conditioner. The control method comprises the steps that the total mileage and the road section road conditions, sent by a vehicle-mounted navigation, of this-time driving are received; the retained driving time reaching a destination is acquired according to a pre-stored average driving speed corresponding to the road conditions of road sections which are not driven on; if the retained driving time is smaller than a first preset value, the vehicle-mounted air conditioner is controlled to stop refrigerating, and a natural wind function of the vehicle-mounted air conditioner is started. According to the control method, device and system for the vehicle-mounted air conditioner, the retained driving time reaching the destination is acquired according to the pre-stored average driving speed corresponding to the road conditions of the road sections, refrigerating of the air conditioner is stopped and the natural wind function of the air conditioner is started a few minutes before reaching the destination, therefore, the temperature change in a vehicle is small, and the taking comfort is not influenced; the temperature in pipelines of the air conditioner rises back to eliminate the temperature difference with the outside, and therefore relative dryness of an air conditioning system is kept to prevent mold from reproducing; meanwhile, ventilating can save more energy resources than refrigerating.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method, device and system for a vehicle air conditioner. Background technique [0002] According to the operation process of the existing car air conditioner, if the air conditioner is turned off after arriving at the destination in summer, the air conditioner system will become moldy, threatening the health of the passengers; therefore, the owner should turn off the air conditioner a few minutes before arriving at the destination and turn on the natural wind. Make the temperature in the air-conditioning pipeline rise up, eliminate the temperature difference with the outside world, so as to keep the air-conditioning system relatively dry and prevent mold from multiplying. [0003] However, in the prior art, after the driver reaches the destination, he usually leaves directly after closing the door of the air-conditioning car. The huge temperature difference in the c...
