The invention relates to the technical field of thermal management system control diagnosis, in particular to a fault diagnosis method and device for a thermal management system, a vehicle, a medium and a product, and the method comprises the steps: obtaining a refrigerant side related parameter, an air side related parameter and a cooling liquid side related parameter; the refrigerant side performance of the heat management system is estimated according to the refrigerant side related parameters; estimating the air side performance of the thermal management system according to the air side related parameters; the cooling liquid side performance of the thermal management system is estimated according to the cooling liquid side related parameters; and calculating a heat exchange ratio between any two of the refrigerant side, the air side and the cooling liquid side according to the refrigerant side performance, the air side performance and the cooling liquid side performance, and determining a fault diagnosis result of the thermal management system. Therefore, the problems of limited diagnosis range, excessive dependence on specific system empirical data, lack of performance virtual estimation and system-level fault diagnosis algorithms, insufficient algorithm universality, lack of actual control and diagnosis application and the like in the prior art are solved.

    本发明涉及热管理系统控制诊断技术领域,特别涉及一种热管理系统的故障诊断方法、装置、车辆、介质及产品,其中,方法包括:获取冷媒侧相关参数、空气侧相关参数和冷却液侧相关参数;根据冷媒侧相关参数估算热管理系统的冷媒侧性能;根据空气侧相关参数估算热管理系统的空气侧性能;根据冷却液侧相关参数估算热管理系统的冷却液侧性能;根据冷媒侧性能、空气侧性能和冷却液侧性能计算冷媒侧、空气侧和冷却液侧中任意两个之间的换热比,并确定热管理系统的故障诊断结果。由此,解决了现有技术中存在诊断范围有限、过度依赖特定系统经验数据、缺乏性能虚拟估算和系统级故障诊断算法、算法泛用性不足以及缺乏实际控制和诊断应用等问题。
