Abstract: A controller area network (CAN) packet automatic analysis method according to the present invention, which comprises the steps of sorting packets related to the performance of a specific function among data packets used in CAN, and comparing and analyzing the change of packet data values with time on the graph, enables a simple and efficient analysis on the function, the type and the operation method of the packet. [Reference numerals] (AA) Start; (BB) End; (ST10) Input data and perform a function?; (ST11) Read a log file and write ID array; (ST12) Calculate a data variation value (A) before performing the function; (ST13) Calculate a difference (B) of average data amount by section before and during performing the function; (ST14) Record and store the variation according to the time relative to a packet satisfying with 'B/A > Threshold value'; (ST15) Performing analysis?; (ST16) Display an analysis result; (ST17) Section '1' increase; (ST18) Section end?
