Control method for vehicle air-conditioning system and vehicle

Abstract

The invention discloses a control method for a vehicle air-conditioning system and a vehicle. The air-conditioning system comprises an air inlet duct, the air inlet duct is provided with an air inletand an air outlet communicated with a cab; an air door is arranged at the air inlet and is suitable for adjusting the proportion of the airflow flow of the inner circulating air duct to the airflow flow of the outer circulating air duct in the air inlet, and an air blower is arranged in the air inlet duct; the control method for the vehicle air conditioning system comprises the steps that the vehicle speed and/or the working state of an air blower are/is detected; the air door adjusts the proportion of the internal circulation air flow rate to the external circulation air flow rate in the airinlet according to the vehicle speed and/or the working state of the air blower. According to the control method for the vehicle air conditioning system, the vehicle speed and/or the working state ofthe air blower are/is detected, the air door is controlled according to the working state to adjust the ratio of the internal circulation air flow to the external circulation air flow in the air inlet, the heating effect in winter is further improved, and cold air is prevented from entering a cab.

Description

Technical field[0001]The present invention relates to the field of vehicle, and more particularly to a control method and a vehicle for a vehicle air conditioning system.Background technique[0002]In the relevant technique, the vehicle air conditioning system on the market is controlled by the external cycle in the winter, which causes the system cold load due to low ambient temperature, and thus the heating effect is not good. Some of the vehicle air conditioning systems use partial circulation in winter, under high speed conditions, there is a cold wind from the outside circulating air, and the intra-circulating air is entered into the crest, which affects the driver's driving experience.Inventive content[0003]The present invention is intended to address at least one of the technical problems present in the prior art. For this reason, it is an object of the present invention to propose a control method for a vehicle air conditioning system, which controls the vehicle speed and / or...

AI Technical Summary

Problems solved by technology

[0002] In related technologies, most of the vehicle air conditioning systems on the market adopt the control method of external circulation in winter, and the cooling load of the system is large due to the low ambient temperature, so the heating effect is not good

Some vehicle air-conditioning systems use partial internal circulation in winter. Under high-speed operating conditions, cold air enters the passenger compartment from the outer circulation air outlet through the inner circulation air outlet, which affects the driving experience of the driver.
