<p>PURPOSE: To provide the vehicle operation information gathering and analyzing system that generates an output enabling unnecessary long idling operation, engine racing, etc., that can not be evaluated from only speed variation to easily be analyzed and evaluated. CONSTITUTION: This system is equipped with an on-vehicle device 3 which gathers vehicle operation information by writing data on the speed and engine rotating speed measured at constant intervals of time on a portable storage medium 4 and an analyzing device 5 which reads in the data on the speed and engine rotating speed out of the storage medium 4, finds speed time-series data and engine rotating speed time-series data showing time-series variations in the speed and engine rotating speed at unit intervals of times T0 -TN from the read data on the speed and engine rotating speed, and draws a graph having the found speed time-series data and engine rotating speed time-series data plotted on the same time scale.</p> |
