    allowing a management section to store pieces of frequency distribution information transmitted by means of the radio communication function of the dynamic state management controller; and

    detecting a decrease in engine output by arranging the pieces of frequency distribution information in time series and by comparing these pieces of frequency distribution information with each other.
