Summary:PURPOSE: A state transition monitoring method of software is provided to output an error event if state change of a processor path is not effective according to the execution of software. CONSTITUTION: An electronic control unit stores an effective process path of software. The electronic control unit obtains state change information about state change of a process path. The electronic control unit determines a process path. If it is not effective state change, the electronic control unit outputs an error event(S33,S35). [Reference numerals] (AA) End; (S17) Setting path valid verification factor as 0; (S19) Path sequence factor of a corresponding process valid path < maximum value?; (S21) Counting path sequence factors; (S23) Counted path sequence factor < a maximum value?; (S25) Is a state of a counted path sequence factor corresponded to a converted state?; (S27) Setting counted path sequence factor as a maximum value; (S29) Setting a path valid factor as 1; (S31) Setting a state of a process target again; (S33) Path valid verification factor = 1?; (S35) Generating an error event
