A new type of automobile meter system is developed.CAN bus is used as the vehicle communication network which connected the display node and the measurement node in the system

and LCD as display screen.The embeded microcontroller and the PIC singlechip processor are respectively the hard cores of the display node and the measurement node.Two-level data fusion technique

including original data fusion and decision-making data fusion

is utilized to enhance data measurment precision with the former and to provide safety decision assitant with the latter

namly to add a new function to the vehicle meter system.The measurement examples show the availablity and the veracity of these technique and methods used in the meter system.
