The invention belongs to the technical field of fault diagnosis, and particularly relates to a valve fault diagnosis method, a heat management device, a storage medium and a controller. On the basis of a cooling liquid coupling heat exchange structure, through a first temperature rise detection step (100) and/or a second temperature rise detection step (200), in combination with the dynamic response/change of a first temperature (019) and a second temperature (029), and on the basis of comparison with a preset threshold value, a fault judgment method of a valve (099) to be diagnosed, a heat management device (600), a storage medium (903), a controller (901) and other products are provided; according to the scheme, a sensor and an actuator do not need to be additionally arranged, judgment can be conducted in combination with the temperature and the statistical value of the temperature such as the integral value, the false alarm problem caused by heat radiation of an engine cabin can be avoided, the method is particularly suitable for function upgrading of a VCU (Vehicle Control Unit) and/or an EMS (Engine Management System) of a hybrid power vehicle, and the method has the advantages of being high in practicability and easy to popularize and use. The method is suitable for an electronic thermostat, an intelligent thermal management module (TMM), a coupling proportion three-way valve and the like.
本发明属于故障诊断技术领域,尤其涉及一种阀故障诊断方法、热管理装置、存储介质及控制器;基于冷却液耦合热交换结构,通过第一温升检测步骤(100)和/或第二温升检测步骤(200),结合第一温度(019)和第二温度(029)的动态响应/变化,在比对预设阈值的基础上,给出了待诊断阀门(099)的故障判定方法和热管理装置(600)、存储介质(903)和控制器(901)等产品;其方案无须添置传感器和执行器,可结合温度及其统计值,如积分值进行判定,并可规避发动机机舱热辐射引起的误报问题,特别适用于混合动力车辆整车控制单元VCU(Vehicle Control Unit)和/或发动机控制单元EMS(Engine Management System)的功能升级,对电子节温器、智能热管理模块TMM(Thermal Management Module)、耦合比例三通阀等均可适用。
