摘　　要：随着汽车行业的发展,对汽车的性能检测、维修、管理提出更高的要求。通过分析多传感器数据融合技术故障诊断方法及汽车诊断系统(故障预测与健康管理)的特点,在不改变当前汽车智能检测系统硬件组成的情况下,将多传感器信息融合技术运用到汽车诊断系统,并且比较智能化分析系统的故障,以及记录下全部传感器和驱动器的数据,实现对汽车系统的实时状态监测、健康评估和故障诊断。In order to integrate detection, maintainanee and management of the car, a higher demand is needed on its economy, security and comfortableness. On the basis of analyzing the fault diagnosis method of muhi-sensor data fusion technique and the characteristics of diagnostic system for vehicles （forecast and health administration）, without changing the hardware of current intelligent system for vehicles, applying the multi-sensor information fusion technology to the diagnostic system for vehicles, comparing the shortages of intelligent system, and recording data of all the sensors and drivers, the real-time status surveillance, health evaluation and fault diagnosis are implemented.
