Hydrogen energy automobile air conditioner control system and method based on discomfort index

Abstract

The invention provides a hydrogen energy automobile air conditioner control method based on an uncomfortable index, and relates to the technical field of hydrogen energy automobiles. The control method comprises the steps: S1, collecting the actual temperature of an air conditioner evaporator and the sunlight intensity outside the hydrogen energy automobile and obtaining the actual air volume of an air conditioner air blower; s2, calculating the sunlight intensity around a driver and passengers in the hydrogen energy automobile; s3, calculating an actual discomfort index Id according to the discomfort index model, wherein when Id is smaller than 60 or larger than 72, calculating the target temperature, corresponding to the target discomfort index Id0, of an air conditioner evaporator according to the sunlight intensity around a driver and passengers in the hydrogen energy automobile and the actual air volume of an air conditioner air blower, and controlling the rotating speed of an air conditioner compressor according to the target temperature of the air conditioner evaporator. The invention further provides a hydrogen energy automobile air conditioner control system based on the discomfort index, the microclimate around the human body of a driver and passengers serves as a regulation and control target and means, control is more comfortable and intelligent, only a sunlight sensor needs to be added, and hardware cost is saved.

Description

technical field [0001] The invention relates to the technical field of air conditioning control, in particular to an air conditioning control system and method based on discomfort index. Background technique [0002] With the deepening of the electrification process of the whole vehicle, more and more air-conditioning system platforms for fuel vehicles need to be considered. In the process of "oil-to-electricity", the compressor is switched from the direct mechanical drive of the original engine through the transmission belt to the electric drive of the controller. question. The speed of the traditional automotive air-conditioning compressor changes with the engine speed, and the control is simple, but precise control cannot be achieved. In the process of "oil to electricity", higher requirements are put forward for the control of electric air-conditioning compressors, but at the same time it brings room for system optimization and improvement. The current electric air con...
