Research on Validation and Research Platform for Automotive Air-Conditioning Control Strategy

In order to improve the efficiency of verification and optimization of control strategies for air-conditioning systems, a thermal management platform is established based on a rapid control prototyping (RCP) approach in the article. The platform is composed of a HVAC hardware bench, a real-time control system, and a control software model. This article describes the overall architecture of the platform, the control strategy, and an efficient method for development and optimization of air-conditioning control strategies. The cooling and heating modes of the air conditioner are tested. The results show that the control strategy can be directly modified via the platform to improve the performance of the whole system. The experimental results show that after modifying the control strategy, the cooling effect of the air conditioner is optimized and the cooling time is reduced by 10.6%. The CLTC cycle is also tested in this work to verify the dynamic control performance of the air-conditioning system. This approach provides a solution for optimizing the control strategy of air-conditioning systems in the future and make a significant contribution to the development of thermal management system testing.
