Air conditioning system for hybrid electric vehicle and control method thereof

Abstract

The invention relates to an air conditioning system for a hybrid electric vehicle and a control method thereof and can solve the problem that the temperature in a vehicle cannot be improved in advance in the prior art. According to the key points of the technical scheme, the air conditioning system for a hybrid electric vehicle comprises a direct current regulated power supply, a vehicle air conditioner, an vehicle engine, as well as hybrid storage battery, an air conditioner controller and a controllable selective switch, wherein the mechanical driving front end of a compressor is driven by the vehicle engine through mechanical linkage, the output end of the hybrid storage battery is connected with the controllable selective switch electrically, the control end of the controllable selective switch is connected with the direct current regulated power supply respectively through controllable switches TL1 and TL2, the first output end of the controllable selective switch is electricallyconnected with an electric drive end, the second output end of the controllable selective switch is connected with an electromagnetic clutch through a controllable switch TL3, the control ends of thecontrollable switches TL1, TL2 and TL3 are all connected with the air conditioner controller electrically. The air conditioning system can be used for adjusting the operation state of an air conditioner according to the use conditions of different vehicles.

Description

technical field [0001] The invention relates to an automobile air-conditioning system and a control method thereof, in particular to a hybrid electric automobile air-conditioning system and a control method thereof capable of automatically adjusting the operating state of the air conditioner according to different automobile usage conditions and interior temperatures. Background technique [0002] As we all know, in today's more and more developed automobile industry, users have put forward higher and higher requirements for the comfort of automobiles. It is very cold in winter in the north and scorching hot in summer in the south. The temperature inside the car makes users very uncomfortable at the beginning of the car start-up. At this time, if the air-conditioning system can be activated in advance to improve the temperature inside the car, it can greatly improve the user's initial experience when starting the car. However, under the existing technical conditions, the po...
