PROBLEM TO BE SOLVED: To improve the persuasive power of the explanation on the quality of the fuel consumption of a user vehicle by calculating and comparing the collection of the instantaneous fuel consumption by the basic mode travel of a maker standard vehicle and the collection of the instantaneous fuel consumption by the general road travel of the user vehicle with a specific equation. SOLUTION: A vehicle travel characteristic analyzing device 10 is fitted to a maker standard vehicle, the standard vehicle is traveled on a chassis mount in a basic mode, and the fuel consumption data are stored and inputted in a personal computer 30 in advance. The analyzing device 10 is fitted to a user vehicle, and data are recorded during a travel on a general road and inputted in the personal computer 30. A calculation and a judgment are made by the personal computer 30 with equations 1, 2, whereτis the instantaneous fuel consumption, (p) is the instantaneous negative pressure, (r) is the instantaneous revolving speed, andαis a constant determined in consideration of the fuel consumption difference between the standard vehicle and the user vehicle. The persuasive power is improved, sincerity is transferred, and a technical explanation can be made. Fuel consumption data can be simply recorded and analyzed.
