Abstract： In order to reduce the energy consumption of the air-conditioning and refrigeration system of new energy vehicles and improve the ability of the system to run smoothly and efficiently, a set of intelligent air-conditioning and refrigeration control system for new energy vehicles was designed and developed from both software and hardware aspects. In terms of software system design, it covers multiple program design parts such as main program, motoResearch and Application of Intelligent Control Systems for New Energy Vehicle Air Conditioning Coolingr start program, current detection program, position sensorless control program, compressor control algorithm program, etc. The hardware circuit design includes the minimum control system circuit, the drive circuit, the rotor position detection circuit, etc. Finally, the work is carried out from the two dimensions of software and hardware, and the entire air-conditioning and refrigeration system is built with the compressor as the core, which effectively controls the speed fluctuation of the motor, improves the anti-interference ability and dynamic control performance, and promotes the development of the intelligent control system of air conditioning and refrigeration of new energy vehicles.
