Abstract: The control calibration of air-conditioning systems is typically conducted during realvehicle testing phases, spanning spring (or autumn), summer, and winter, with a calibration cycle as long as 10 months, significantly impacting the vehicle's launch timeline. To shorten the airconditioning system calibration cycle while ensuring vehicle quality, this paper introduces a digital twin-based virtual calibration technology for air-conditioning, which replaces real-vehicle calibration. The real-vehicle test under a single operating condition takes 5 000 s, while the virtual calibration only requires 400 s, making the virtual simulation speed more than ten times faster than real-vehicle testing. During the project development phase, the control calibration of the entire vehicle's airconditioning system can be achieved, allowing for early functional testing of the air-conditioning system, improving the maturity of the air-conditioning system control, significantly reducing the real-vehicle calibration cycle, and enhancing product competitiveness.
Key words: air conditioning system; virtual calibration; grade of maturity; calibration cycle
摘要: 空调系统的控制标定通常在实车测试阶段开展,持续的测试时间经过春(秋)、夏和冬 季,其标定周期长达 10 个月,严重影响车辆上市时间。为了在缩短空调系统标定周期的同时 保障车辆的质量,文章提出一种数字孪生的空调虚拟标定技术代替实车标定,通过测试可知, 实车单工况用时 5 000 s,通过虚拟标定只需 400 s,虚拟仿真速度是实车试验的十倍以上。在 项目开发阶段,使用虚拟标定可实现整车空调系统的控制标定,并提前进行空调系统的功能 性测试,提高空调系统控制的成熟度,大大削减实车标定周期,提升产品竞争力。
