Heavy vehicle health state assessment method and system, and data storage system

The invention relates to the technical field of vehicles, and provides a heavy vehicle health state assessment method and system, and a data storage system. The health status assessment method comprises the following steps: acquiring monitoring data; judging whether the working condition of the system is stable or not based on the monitoring data; if yes, calculating a part-level health index, a system-level health index and a whole vehicle-level health index in sequence; according to the component-level health index, determining a component health level; determining a system health level according to the system-level health index; determining the vehicle health level according to the vehicle level health index; otherwise, ending. 本发明涉及车辆技术领域，提供了一种重型车辆健康状态评估方法及系统、数据存储系统。健康状态评估方法包括，获取监测数据；基于监测数据，判断系统所处工况是否稳定；若是，依次计算部件级健康指数、系统级健康指数和整车级健康指数；根据部件级健康指数，确定部件健康等级；根据系统级健康指数，确定系统健康等级；根据整车级健康指数，确定整车健康等级；否则，结束。
