The invention discloses a vehicle health management method and system, and the method comprises the steps that a main health monitoring node collects various types of vehicle fault information, and the various types of vehicle fault information comprise vehicle standard diagnosis information, wiring harness fault information, ECU health state information and key predictability index information; obtaining fault levels and corresponding weights of the various types of vehicle fault information; the main health monitoring node judges whether the fault level of the collected vehicle fault information meets a triggering condition for generating a vehicle health report or not, and if the fault level of any type of vehicle fault information meets the triggering condition, a vehicle health report containing a whole vehicle health index is generated; the whole vehicle health index is obtained through calculation of the vehicle fault information and the weight. According to the invention, a more valuable reference basis is provided for further after-sales problem investigation, the vehicle health condition is visually and clearly expressed through the vehicle health index, and the fault diagnosis efficiency and experience are improved.
本发明公开一种车辆健康管理方法及系统,其中,车辆健康管理方法包括:主健康监控节点收集各类车辆故障信息,所述各类车辆故障信息包括车辆标准诊断信息、线束故障信息、ECU健康状态信息和关键预知性指标信息,以及所述各类车辆故障信息的故障等级和对应的权重;主健康监控节点判断收集的车辆故障信息的故障等级是否满足生成车辆健康报告的触发条件,若任一类别的车辆故障信息的故障等级满足所述触发条件,则生成含有整车健康指数的车辆健康报告,所述整车健康指数通过所述车辆故障信息和所述权重计算获得。本发明对售后进一步问题排查提供了更有价值的参考依据,通过车辆健康指数直观明了地表达车辆健康状况,提升了故障诊断效率和体验。
