摘　　要：汽车空调动态负荷的准确计算对提高汽车行驶过程中乘员的舒适性和降低整车能耗具有重要意义,目前多数热负荷计算软件只是一种线下计算工具,不具有实时性。采用STM32单片机与CAN总线通讯模块,实现了汽车空调动态热负荷的实时计算,并通过试验测得动态热负荷计算时长小于24 s,满足动态热负荷计算的实时性要求。同时提出将动态热负荷计算与热负荷控制相结合,在提高舒适性的同时降低汽车的能耗。Accurate calculation of the dynamic load of automobile air conditioners is of great significance for improving the passenger comfort and reducing the energy consumption of the entire vehicle during the actual driving process.However,the calculation process of dynamic vehicle thermal load is complicated.Most thermal load calculation software is only an offline calculation tool and does not have real-time performance.In this paper,the STM32 single-chip microcomputer and CAN bus communication module are used to realize the real-time calculation of the dynamic heat load of the automobile air conditioner.The test shows that the dynamic heat load calculation process takes less than 24 s and meets the real-time requirements of the dynamic heat load calculation.At the same time,the combination of dynamic heat load calculation and heat load control is proposed to improve the comfort of automobile air conditioning systems and reduce energy consumption.
